NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED

NOTE 1. OVERVIEW AND BASIS OF PRESENTATION

Trimble Navigation Limited (“we,” “Trimble” or the “Company”), incorporated in California in 1981, provides positioning product solutions to commercial and government users in a large number of markets. These markets include surveying, construction, agriculture, urban and resource management, military, transportation and telecommunications.

Trimble has a 52-53 week fiscal year, ending on the Friday nearest to December 31, which for fiscal 2005 was December 30. The first fiscal quarters of 2006 and 2005 ended on March 31, 2006 and April 1, 2005, respectively. Fiscal 2006 and 2005 are 53-week years. Unless otherwise stated, all dates refer to its fiscal year and fiscal periods.

The accompanying financial data as of March 31, 2006 and for the three months ended March 31, 2006 and April 1, 2005 has been prepared by the Company, without audit, 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 U.S. have been condensed or omitted pursuant to such rules and regulations. The following discussion should be read in conjunction with Trimble’s 2005 Annual Report on Form 10-K.

In first quarter of fiscal 2006, the Company revised its statements of cash flows for the first quarter of fiscal 2005. The changes relate to the Company’s classification of the foreign exchange impact on its cash and cash equivalents that was erroneously included in cash flows from operations. These corrections have been made retrospectively modifying the presentation for the first quarter of fiscal 2005. The changes resulted in an increase to cash flows used in operations of $0.9 million for the first quarter of fiscal 2005. This revision to the statements of cash flows had no impact on the Company’s cash and cash equivalents, balance sheet, or income statement.

In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of financial position as of March 31, 2006, results of operations for the three months ended March 31, 2006 and April 1, 2005 and cash flows for the three months ended March 31, 2006 and April 1, 2005, as applicable, have been made. The results of operations for the three months ended March 31, 2006 are not necessarily indicative of the operating results for the full fiscal year or any future periods.

The preparation of financial statements in accordance with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Trimble’s critical accounting policies are those that affect its financial statements materially and involve difficult, subjective or complex judgments by management. For the first quarter of fiscal 2006, the Company changed its critical accounting policy related to stock-based compensation. See Note 2 to the Notes to the Condensed Consolidated Financial Statements for additional information. For more information on the Company’s significant accounting principles, refer to Trimble’s 2005 Annual Report on Form 10-K.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

SFAS No. 123R “Share-Based Payment”

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Standard of Financial Accounting Standards No. 123(R), “Share-Based Payment” (“SFAS 123(R)”). SFAS 123(R) requires employee stock options and rights to purchase shares under stock participation plans to be accounted for under the fair value method, and eliminates the ability to account for these instruments under the intrinsic value method prescribed by APB Opinion No. 25, and allowed under the original provisions of SFAS 123.

Trimble has adopted SFAS 123(R) using the modified prospective method which requires the  adoption of the accounting standard for fiscal periods beginning after June 15, 2005. As a result, the Company's financial statements for fiscal periods after December 30, 2005 will include stock-based compensation expenses that are not comparable to financial statements of fiscal periods prior to December 30, 2005. SFAS 123(R) requires stock-based compensation to be estimated using the fair value on the date of grant using an option-pricing model. The value of the portion of the award that is expected to vest is recognized as expense over the related employees' requisite service periods in the Company’s Condensed Consolidated of Income. Prior to the adoption of SFAS 123(R), the Company accounted for stock-based compensation to employees and directors using the intrinsic value method in accordance with APB Opinion No. 25 as allowed under Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”). Under the intrinsic value method, no stock-based compensation expense had been recognized in the Company’s Condensed Consolidated Statement of Income because the exercise price of the Company’s stock options granted to employees and directors equaled the fair market value of the underlying stock at the date of grant.

See Note 3 to the Notes to the Condensed Consolidated Financial Statements for additional information.

NOTE 3. STOCK-BASED COMPENSATION

In accordance with the provisions of Statement of Financial Accounting Standards No. 123 (“SFAS 123”), "Accounting for Stock-Based Compensation" and “Statement of Financial Accounting Standards No. 148” (“SFAS 148”), “Accounting for Stock-Based Compensation - Transition and Disclosure,” Trimble applied Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (“APB 25”) and related interpretations in accounting for its stock option plans and stock purchase plan prior to fiscal 2006. Accordingly, Trimble did not recognize compensation cost for stock-based compensation prior to fiscal 2006. For periods subsequent to fiscal 2005, Trimble will recognize expense related to stock-based compensation in accordance with SFAS 123(R).

The following table summarizes stock-based compensation expense, net of tax, related to employee stock-based compensation included in the Condensed Consolidated Statements of Income in accordance with SFAS 123(R) for the three months ended March 31, 2006 and April 1, 2005.

OPTIONS

Stock option expense recognized during the period is based on the value of the portion of share-based payment awards that is expected to vest during the period. Stock option expense recognized in the Company’s Condensed Consolidated of Income for the three months ended March 31, 2006 included compensation expense for stock options granted prior to, but not yet vested as of December 30, 2005 based on the grant date fair value estimated in accordance with the provisions of SFAS 123 and compensation expense for the stock options granted subsequent to December 30, 2005 based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). In conjunction with the adoption of SFAS 123(R), the Company changed its method of attributing the value of stock option to expense from the accelerated multiple-option approach to the straight-line single option method. Compensation expense for all stock options granted on or prior to December 30, 2005 will continue to be recognized using the accelerated multiple-option approach while compensation expense for all stock options granted subsequent to December 30, 2005 is recognized using the straight-line single-option method. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Company’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred.

Stock Option Plans

Trimble issues new shares upon exercises of stock options related to the following plans.

2002 Stock Plan

In 2002, Trimble’s Board of Directors adopted the 2002 Stock Plan (“2002 Plan”). The 2002 Plan, as amended to date and approved by shareholders, approved by the shareholders provides for the granting of incentive and non-statutory stock options for up to 4,500,000 shares plus any shares currently reserved but unissued to employees, consultants, and directors of Trimble. Incentive stock options may be granted at exercise prices that are not less than 100% of the fair market value of Common Stock on the date of grant. Employee stock options granted under the 2002 Plan have 120-month terms, and vest at a rate of 20% at the first anniversary of grant, and monthly thereafter at an annual rate of 20%, with full vesting occurring at the fifth anniversary of the grant. The exercise price of non-statutory stock options issued under the 2002 Plan must be at least 85% of the fair market value of Common Stock on the date of grant.

1993 Stock Option Plan

In 1992, Trimble's Board of Directors adopted the 1993 Stock Option Plan (“1993 Plan”). The 1993 Plan, as amended to date and approved by shareholders, provided for the granting of incentive and non-statutory stock options for up to 9,562,500 shares of Common Stock to employees, consultants, and directors of Trimble. Incentive stock options may be granted at exercise prices that are not less than 100% of the fair market value of Common Stock on the date of grant. Employee stock options granted under the 1993 Plan have 120-month terms, and vest at a rate of 20% at the first anniversary of grant, and monthly thereafter at an annual rate of 20%, with full vesting occurring at the fifth anniversary of grant. The exercise price of non-statutory stock options issued under the 1993 Plan must be at least 85% of the fair market value of Common Stock on the date of grant.

1992 Management Discount Stock Option Plan

In 1992, Trimble's Board of Directors and shareholders approved the 1992 Management Discount Stock Option Plan ("Discount Plan"). Employee stock options granted under the 1992 Plan have 120-month terms, and vest at a rate of 20% at the first anniversary of grant, and monthly thereafter at an annual rate of 20%, with full vesting occurring at the fifth anniversary of the grant.

1990 Director Stock Option Plan

In December 1990, Trimble adopted a Director Stock Option Plan under which an aggregate of 570,000 shares of Common Stock have been reserved for issuance to non-employee directors as approved by the shareholders to date. Stock options issued under this plan vest generally over a three year period.

Option Activity

Activity during the first quarter of fiscal 2006 under the combined plans was as follows:

	March 31, 2006
Fiscal Years Ended	Options	Weighted average exercise price
(In thousands, except for per share data)
Outstanding at December 30, 2005	6,414	$18.70
Granted	70	36.47
Exercised	(536)	14.51
Forfeited/Cancelled/Expired	(16)	25.07
Outstanding at March 31, 2006	5,932	19.27

Options Outstanding and Exercisable

Exercise prices for options outstanding and exercisable as of March 31, 2006, ranged from $5.33 to $43.43. Options outstanding and exercisable consist of fully vested options and options expected to vest at March 31, 2006. The aggregate intrinsic value is the total pretax intrinsic value based on the Company’s closing stock price of $45.05 as of March 31, 2006, which would have been received by the option holders had all option holders exercised their options as of that date.

		Weighted-	Weighted-
		Average	Average	Aggregate
	Number	Exercise Price	Remaining	Intrinsic
	Of Shares	per Share	Contractual Term	Value
			(in years)	(in thousands)
Options Outstanding and Expected to Vest	5,776,734	$    19.01	5.9	$    150,413
Options Exercisable	3,495,154	14.71	5.0	106,026

As of March 31, 2006, the total unamortized stock option expense is $18.3 million with weighted-average recognition period of 1.6 years.

Valuation Assumptions

For options granted prior to October 1, 2005, the fair value for these options was estimated at the date of grant using the Black-Scholes option-pricing model. For stock options granted on or after October 1, 2005, the fair value of each award is estimated on the date of grant using a binomial valuation model. Similar to the Black-Scholes model, the binomial model takes into account variables such as volatility, dividend yield rate, and risk free interest rate. In addition,the binomial model incorporates actual option-pricing behavior and changes in volatility over the option’s contractual term. For these reasons, the Company believes that the binomial model provides a fair value that is more representative of actual experience and future expected experience than the value calculated using the Black-Scholes model.

Under the Black-Scholes and binomial models, the estimated values of employee stock options granted during the first quarter of fiscal 2006 and 2005 were $14.53 and $16.21, respectively. The value of each option grant is estimated on the date of grant using the binomial model for options granted during the first quarter of fiscal 2006 and the Black-Scholes option pricing model for options granted during the first quarter of fiscal 2005 and with the following assumptions:

Fiscal Years Ended	March 31, 2006	April 1, 2005
Expected dividend yield	--	--
Expected stock price volatility	42.0%	57.4%
Risk free interest rate	4.5%	4.2%
Expected life of options (in years)	4.6	4.7

Page 9

Expected Dividend Yield - The dividend yield assumption is based on the Company’s history and expectation of dividend payouts.

Expected Stock Price Volatility - The Company’s computation of expected volatility is based on a combination of implied volatilities from traded options on the Company’s stock and historical volatility. The Company used implied and historical volatility as the combination was more representative of future stock price trends than historical volatility alone.

Expected Risk Free Interest Rate - The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option.

Expected Life Of Option - The Company’s expected term represents the period that the Company’s stock options are expected to be outstanding and was determined based on historical experience of similar stock options with consideration to the contractual terms of the stock options, vesting schedules and expectations of future employee behavior.

EMPLOYEE STOCK PURCHASE PLAN

Stock-based compensation expense related to the Company’s employee stock purchase plan is recognized during the purchase vesting period which is generally six months.

Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (“Purchase Plan”) under which an aggregate of 5,325,000 shares of Common Stock have been reserved for sale to eligible employees as approved by the shareholders to date. The plan permits full-time employees to purchase Common Stock through payroll deductions at 85% of the lower of the fair market value of the Common Stock at the beginning or at the end of each six-month offering period. The Purchase Plan terminates on September 8, 2008.

Valuation Assumptions

The fair value of rights granted under the Employee Stock Purchase Plan is estimated at the date of grant using the Black-Scholes option-pricing model. The following weighted-average assumptions were used at March 31, 2006 and April 1, 2005:

Three Months Ended	March 31, 2006	April 1, 2005
Expected dividend yield	--	--
Expected stock price volatility	34.9%	35.1%
Risk free interest rate	4.4%	3.4%
Expected life of purchase	0.5	0.5

Expected Dividend Yield - The dividend yield assumption is based on the Company’s history and expectation of dividend payouts.

Expected Stock Price Volatility - The Company’s computation of expected volatility is based on implied volatilities from traded options on the Company’s stock. The Company used implied volatility because it is representative of future stock price trends during the six month purchase period.

Expected Risk Free Interest Rate - The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the purchase period.

Expected Life Of Purchase - The Company’s expected life of the purchase is based on the 6 month offering period of the purchase plan.

Trimble acts as a contract manufacturer for CTCT. Products are manufactured based on orders received from CTCT and are sold at cost plus a mark up to CTCT. CTCT resells products to both Caterpillar and Trimble for sales through their respective distribution channels. Generally, Trimble sells products to its after market dealer channel, and Caterpillar sells products for factory and dealer installation. CTCT does not hold inventory in that the resale of products to Caterpillar and Trimble occur simultaneously when the products are purchased from Trimble.

Beginning in the first fiscal quarter of 2006, Trimble included the impact of certain transactions with CTCT in revenue and cost of sales. Revenue and cost of sales were recorded for the manufacturing of products that are sold to CTCT and then sold through the Caterpillar distribution channel. Cost of sales transactions include purchasing products from CTCT at a higher price than Trimble's original manufacturing costs, partially offset by contract manufacturing fees charged to CTCT. Prior to the first fiscal quarter of 2006, these transactions were included in expenses for affiliated operations, net in the non-operating income (expense), net of the Consolidated Statements of Income. The change in presentation resulted from the Company’s assessment of CTCT’s advancement and ability to function as a stand-alone company. As a result of CTCT’s progression, the Company recognized the remaining deferred gain balance of $9.2 million in the fourth quarter of fiscal 2005. In addition, the Company’s exclusive manufacturing agreement with CTCT ended during the second half of fiscal 2005. As a result, the Company deemed transactions between CTCT and Trimble to be arms-length during the first quarter of fiscal 2006 and concluded they should be presented similarly to other vendor and customer relationships. The impact of this change in presentation during the first quarter of fiscal 2006 was a net impact of $5.2 million decrease in gross margins. There was no impact on net income.

Trimble received reimbursement of employee-related costs from CTCT for Trimble employees dedicated to CTCT or performing work for CTCT totaling $3.4 million and $2.6 million for the three months ended March 31, 2006 and April 1, 2005, respectively. The reimbursements were offset against operating expenses.

Trimble's 50% share of CTCT's reported gain (loss)	1.6	0.3
Total CTCT income (expense) for affiliated operations, net (1)	$1.6	$ (2.8)

(1) Due to the nature of the relationship between Trimble and CTCT, a related party, the impact of these agreements is classified under non-operating income (expense) under the heading of "Income (Expense) for affiliated operations, net."

At March 31, 2006, the net outstanding balance due to CTCT from Trimble was approximately $1.5 million recorded within heading of accounts payable. The net outstanding balance due from CTCT was $0.2 million at December 30, 2005 and is included in account receivables, net.

Nikon-Trimble Joint Venture

On March 28, 2003, Trimble and Nikon Corporation entered into an agreement to form a joint venture in Japan, Nikon-Trimble Co., Ltd., as described in Trimble’s 2005 Annual Report on Form 10-K. Nikon-Trimble began operations in July, 2003 and is equally owned by Trimble and Nikon, with equal voting rights.

Page 11

Nikon-Trimble is the distributor in Japan for Nikon and Trimble products. Trimble is the exclusive distributor outside of Japan for Nikon branded survey products. For products sold from Trimble to the Nikon-Trimble, revenue is recognized by Trimble on a sell-through basis from Nikon-Trimble to the end customer. Profits from these inter-company sales are eliminated.

The terms and conditions of the sales of products from Trimble to Nikon-Trimble are comparable with those of the standard distribution agreements which Trimble maintains with its dealer channel and margins earned are similar to those from third party dealers. Similarly, the purchases of product by Trimble from the Nikon-Trimble are made on terms comparable with the arrangements which Nikon maintained with its international distribution channel prior to the formation of the joint venture with Trimble.

Trimble has adopted the equity method of accounting for its investment in Nikon-Trimble, with 50% share of profit or loss from this joint venture to be reported by Trimble in the Non-operating section of the Condensed Consolidated Statement of Income under the heading of “Expenses for affiliated operations, net.” For the three months ended March 31, 2006 and April 1, 2005, Trimble reported a loss of $15,000 and $0.2 million, respectively, as its proportionate share of the net loss of the joint venture. At March 31, 2006 and December 30, 2005, the net payable by Trimble to Nikon-Trimble related to the purchase and sale of products from and to Nikon-Trimble is $3.8 million and $2.0 million, respectively, recorded within accounts payable on the Condensed Consolidated Balance Sheets. The carrying amount of the investment in Nikon Trimble was approximately $12.9 million at March 31, 2006 and $12.9 million at December 30, 2005.

NOTE 7. THE COMPANY AND SEGMENT INFORMATION:

Trimble is a designer and distributor of positioning products and applications enabled by GPS, optical, laser, and wireless communications technology. Trimble provides products for diverse applications in its targeted markets.

To achieve distribution, marketing, production, and technology advantages, Trimble manages its operations in the following four segments:

·   Engineering and Construction — Consists of products currently used by survey and construction professionals in the field for positioning, data collection, field computing, data management, and machine guidance and control. The applications served include surveying, road, runway, construction, site preparation and building construction.

·   Field Solutions — Consists of products that provide solutions in a variety of agriculture and geographic information systems (GIS) applications. In agriculture these include precise land leveling and machine guidance systems. In GIS they include handheld devices and software that enable the collection of data on assets for a variety of governmental and private entities.

·   Mobile Solutions — Consists of products that enable end users to monitor and manage their mobile assets by communicating location and activity-relevant information from the field to the office. Trimble offers a range of products that address a number of sectors of this market including truck fleets, security, and public safety vehicles.

·   Advanced Devices — The various operations that comprise this segment were aggregated on the basis that no single operation accounted for more than 10% of Trimble’s total revenue, operating income and assets. This segment is comprised of the Component Technologies, Military and Advanced Systems, Applanix and Trimble Outdoors businesses.

Page 13

Trimble evaluates each of its segment's performance and allocates resources based on segment operating income from operations before income taxes, and some corporate allocations. Trimble and each of its segments employ the same accounting policies.

In the first fiscal quarter of 2006, Trimble combined the operating results of Components Technologies and Portfolio Technologies and included the combined operating results in Advanced Devices. The change in presentation was made in recognition of the small size of each of the businesses relative to the total company. The presentation of prior period’s segment operating results has been changed to conform to the Company’s current segment presentation.  

The following table presents revenues, operating income (loss), and identifiable assets for the four segments. Operating income (loss) is net revenue less operating expenses, excluding general corporate expenses, amortization, restructuring charges, non-operating income (expense), and income taxes. The identifiable assets that Trimble's Chief Operating Decision Maker views by segment are accounts receivable and inventory.

NOTE 8. LONG-TERM DEBT:

Credit Facilities

On July 28, 2005, Trimble entered into a $200 million unsecured revolving credit agreement (“2005 Credit Facility”) with a syndicate of 10 banks with The Bank of Nova Scotia as the administrative agent. The 2005 Credit Facility replaced the Company’s $175 million secured 2003 Credit Facility. The funds available under the new 2005 Credit Facility may be used by the Company for general corporate purposes and up to $25 million of the 2005 Credit Facility may be used for letters of credit.

The Company may borrow funds under the 2005 Credit Facility in U.S. Dollars or in certain other currencies, and will bear interest, at the Company's option, at either: (i) a base rate, based on the administrative agent's prime rate, plus a margin of between 0% and 0.125%, depending on the Company's leverage ratio as of its most recently ended fiscal quarter, or (ii) a reserve-adjusted rate based on LIBOR, EURIBOR, STIBOR or other agreed-upon rate, depending on the currency borrowed, plus a margin of between 0.625% and 1.125%, depending on the Company's leverage ratio as of the most recently ended fiscal quarter. The Company's obligations under the 2005 Credit Facility are guaranteed by certain of the Company's domestic subsidiaries.

The 2005 Credit Facility contains customary affirmative, negative and financial covenants including, among other requirements, negative covenants that restrict the Company's ability to dispose of assets, create liens, incur indebtedness, repurchase stock, pay dividends, make acquisitions, make investments, enter into mergers and consolidations and make capital expenditures, and financial covenants that require the maintenance of leverage and fixed charge coverage ratios. The 2005 Credit Facility contains events of default that include, among others, non-payment of principal, interest or fees, breach of covenants, inaccuracy of representations and warranties, cross defaults to certain other indebtedness, bankruptcy and insolvency events, material judgments, and events constituting a change of control. Upon the occurrence and during the continuance of an event of default, interest on the obligations will accrue at an increased rate and the lenders may accelerate the Company's obligations under the 2005 Credit Facility, however that acceleration will be automatic in the case of bankruptcy and insolvency events of default. Trimble incurs a commitment fee if the 2005 Credit Facility is not used. The commitment fee is not material to the Company’s results during all periods presented.

Page 15

At March 31, 2006, the Company had a zero balance outstanding under the 2005 Credit Facility and was in compliance with all financial covenants.

Promissory Note

As of March 31, 2006, the Company had other notes payable totaling approximately $0.6 million consisting of government loans to foreign subsidiaries.

NOTE 9. PRODUCT WARRANTIES:

The Company accrues for warranty costs as part of its cost of sales based on associated material product costs, technical support labor costs, and costs incurred by third parties performing work on Trimble's behalf. The products sold are generally covered by a warranty for periods ranging from 90 days to three years, and in some instances up to 5.5 years.

While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, its warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage, or service delivery costs differ from the estimates, revisions to the estimated warranty accrual and related costs may be required.

Changes in the Company’s product warranty liability during the three months ended March 31, 2006 and April 1, 2005 are as follows:

	March 31, 2006		April 1, 2005
Three Months Ended

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

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to product returns, doubtful accounts, inventories, investments, intangible assets, income taxes, warranty obligations, restructuring costs, and contingencies and litigation. 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 amount and timing of revenue and expenses and the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. See the discussion of our critical accounting policies under the heading Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for fiscal 2005.

RESULTS OF OPERATIONS

Overview

The following table is a summary of revenue and operating income for the periods indicated and should be read in conjunction with the narrative descriptions below.

	Three Months Ended
	March 31,	April 1,
	2006	2005
(Dollars in thousands)
Total consolidated revenue	$ 225,854	$ 195,383
Gross Margin	107,463	97,807
Gross Margin %	47.6%	50.1%
Total consolidated operating income	33,065	30,200
Operating Income %	14.6%	15.5%

Revenue

In the fiscal quarter ended March 31, 2006, total revenue increased by $30.5 million or 15.6%, as compared to the same corresponding period in fiscal 2005. The increase was primarily due to stronger performances in our Engineering and Construction and Mobile Solutions segments. The Engineering and Construction and Mobile Solutions segments increased $26.5 million and $5.2 million, respectively, compared to the same corresponding period in fiscal 2005. Revenue growth within these segments was primarily driven by new product introductions and increased penetration of existing markets. Both the Engineering and Construction and Mobile Solutions segments also benefited from the impact of acquisitions. This was partially offset by a $4.3 million decrease due to foreign currency fluctuations, primarily the strengthening of the dollar versus the Euro year over year.

Page 19

During the first fiscal quarter of fiscal 2006, sales to customers in the United States represented 56%, Europe represented 25%, Asia Pacific represented 10% and other regions represented 9% of our total revenues. During the same corresponding period in fiscal 2005, sales to customers in the United States represented 54%, Europe represented 23%, Asia Pacific represented 11% and other regions represented 12% of our total revenues.

Gross Margin

Our gross margin varies due to a number of factors including product mix, pricing, distribution channel used, the effects of production volumes, new product start-up costs, and foreign currency translations. Gross margin as a percentage of total revenues was 47.6% and 50.1% for the first quarter of fiscal 2006 and 2005, respectively. The decrease was primarily due to the inclusion of CTCT transactions of $5.2 million that were not present in corresponding period in fiscal 2005, amortization of software-related acquired intangibles of $0.9 million and stock-based compensation expense of $0.3 million that were not included in gross margins during the first quarter of fiscal 2005. This was partially offset by improvements in product mix due to stronger sales of our new, higher margin products, and higher revenue.

Operating Income

Operating income as a percentage of total revenue was 14.6% and 15.5% for the first quarter of fiscal 2006 and 2005, respectively. The decrease is driven by the inclusion of CTCT transactions of $5.2 million that were not present in corresponding period in fiscal 2005 and stock-based compensation expense of $3.2 million that were not included in operating income during the first quarter of fiscal 2005. This was partially offset by an increase in revenues higher underlying gross margins and operating leverage.

Results by Segment

To achieve distribution, marketing, production, and technology advantages in our targeted markets, we manage our operations in the following four segments: Engineering and Construction, Field Solutions, Mobile Solutions, and Advanced Devices. Operating income (loss) equals net revenue less cost of sales and operating expenses, excluding general corporate expenses, amortization of purchased intangibles, restructuring charges, non-operating income (expense), and income taxes.

In the first fiscal quarter of 2006, we combined the operating results of Components Technologies and Portfolio Technologies and included the combined operating results in Advanced Devices. The change in presentation was made in recognition of the small size of each of the businesses relative to the total company. The presentation of prior period’s segment operating results has been changed to conform to our current segment presentation. We did not restate prior SEC filings to reflect this change in presentation.

The following table is a breakdown of revenue and operating income by segment (in thousands, except percentages):

Consolidated income before income taxes	$ 35,872	$ 26,423

Engineering and Construction

Engineering and Construction revenues increased by $26.5 million or 22.1% while segment operating income increased $4.9 million or 22.7% for the three months ended March 31, 2006 as compared to the same corresponding period in fiscal 2005. The revenue growth was driven by growth of existing products such as the Trimble S6, machine control products, and the Trimble R8 GPS System. Revenue growth was also attributed to the acquisitions during fiscal 2005. Segment operating income increased as a result of higher revenues and increased sales of higher margin products, partially offset by $4.9 million in net expenses related to CTCT transactions and $1.0 million in stock-based compensation expense that were not present in the first quarter of fiscal 2005.

Field Solutions

Field Solutions revenues decreased by $2.4 million or 5.2% while segment operating income decreased $1.7 million or 10.7% for the three months ended March 31, 2006 as compared to the same corresponding periods in fiscal 2005. Revenue decreased primarily due to lower sales of our agriculture products and the absence of strong introductory products such as the AgGPS® EZ-Guide® System and AgGPS® EZ-Steer™ Systems that were introduced in the first quarter of fiscal 2005, partially offset by increased sales of our geographic information systems products. The decrease in segment operating income was primarily due to lower revenues, shifts in product mix, $0.3 million in expenses related to CTCT transactions and $0.2 million in stock-based compensation expense that were not present in the first quarter of fiscal 2005.

Mobile Solutions

Mobile Solutions revenues increased by $5.2 million or 70.3% while segment operating income increased by $0.9 million or 135.1% for the three months ended March 31, 2006 as compared to the corresponding period in fiscal 2005. Revenues grew due to acquisitions made in fiscal 2005 that were not present in the first quarter of fiscal 2005, increased subscriber growth, an increase in sales to ready-mix suppliers, and increased sales from our dealer channel. Operating income increased for the first three months of fiscal 2006 versus the same period last year due to increased revenues, particularly high margin service revenues, partially offset by $0.2 million in stock-based compensation expense which was not present in the first quarter of fiscal 2005.

Page 21

Advanced Devices

Advanced Devices revenues increased by $1.1 million or 5.0% while operating income decreased by $0.9 million or 28.1% for the three months ended March 31, 2006 as compared to the corresponding period in fiscal 2005. The increase in revenue was primarily due to stronger performance in our Applanix airborne products and in-vehicle navigation businesses which were offset by lower revenue in our timing and military advanced systems products. The decrease in operating income was primarily due to unfavorable product mix and $0.5 million in stock-based compensation which was not present in the first quarter of fiscal 2005.

Research and Development, Sales and Marketing, and General and Administrative Expenses

Research and development (“R&D”), sales and marketing (“S&M”), and general and administrative (“G&A”) expenses are summarized in the following table (in thousands, except percentages):

	Three Months Ended
		March 31,		April 1,
		2006		2005
(In thousands)
Research and development	$	24,446	$	21,828
Percentage of revenue		10.8%		11.2%
Sales and marketing		32,706		30,371
Percentage of revenue		14.5%		15.5%
General and administrative		15,761		12,832
Percentage of revenue		7.0%		6.6%
Total	$	72,913	$	65,031
Percentage of revenue		32.3%		33.3%

Overall, R&D, S&M, and G&A expense increased by approximately $7.9 million in the first quarter of fiscal 2006 compared to the same corresponding period in fiscal 2005. Included in the increase was approximately $2.9 million of stock-based compensation not included in the prior year period.

The increase in R&D expenses in the first quarter of fiscal 2006 as compared with the first quarter of fiscal 2005 was primarily due to the inclusion of expenses from acquisitions not applicable in the prior year in the amount of $0.9 million, $0.8 million increase in R&D equipment and materials related expenses, $0.6 million in stock-based compensation expense which was not present in the first quarter of fiscal 2005, and $0.5 million increase in salaries, partially offset by $0.6 million decrease due to foreign currency fluctuations. All of our R&D costs have been expensed as incurred.

* We believe that the development and introduction of new products are critical to our future success and we expect to continue active development of new products.

The increase in S&M expenses in the first quarter of fiscal 2006 as compared with the first quarter of fiscal 2005 was primarily due to $1.0 million increase in tradeshow related expenses, $0.7 million in stock-based compensation expense which was not present in the first quarter of fiscal 2005, inclusion of expenses from acquisitions not applicable in the prior year in the amount of $0.6 million, and $0.2 million increase in salary related expenses, partially offset by $0.7 million decrease due to foreign currency fluctuations.

* Our future growth will depend in part on the timely development and continued viability of the markets in which we currently compete as well as our ability to continue to identify and develop new markets for our products.

The increase in G&A expenses in the first quarter of fiscal 2006 as compared with the first quarter of fiscal 2005 was primarily due to the inclusion of expenses from acquisitions not applicable in the prior year in the amount of $1.3 million and $1.6 million in stock-based compensation expense which was not present in the first quarter of fiscal 2005.

Amortization of Purchased Intangible Assets

Amortization of purchased intangible assets included in operating expenses was $2.4 million, of which $0.9 million was recorded in cost of sales in the first quarter of fiscal 2006, compared with $2.3 million in the first quarter of fiscal 2005. The decrease was primarily due to certain acquired intangible assets that were fully amortized during the third quarter of fiscal 2005.

Page 22

Restructuring Charges

We did not record any restructuring charge during the first quarter of fiscal 2006. In the comparable first quarter of fiscal 2005, we recorded a restructuring charge of approximately $0.3 million associated with closure of one of its offices as a result of integration efforts of a previous acquisition. Payments of $0.1 million and $0.1 million were made during the three months period ending March 31, 2006 and April 1, 2005 relating to previous restructuring plans.  As of March 31, 2006, the remaining restructuring accrual balance is $0.2 million which is related to the office closure expected to be paid over the next several years. The restructuring accrual is included on the Condensed Consolidated Balance Sheets under the heading of “Accrued Liabilities.”

Non-operating Income (Expense), Net

The components of non-operating income (expense), net, are as follows (in thousands):

	Three Months Ended
	March 31,	April 1,
	2006	2005
Interest income (expense), net	$ 434	$ (611)
Foreign currency transaction gain (loss), net	593	(157)
Income (expenses) for affiliated operations, net	1,616	(3,039)
Other income, net	164	30
Total non-operating income (expense), net	$ 2,807	$ (3,777)

Page 23

Non-operating income (expense), net increased by $6.6 million or 173.7% during the first quarter of fiscal 2006, as compared with the corresponding period in fiscal 2005 primarily due to an increase in net interest income of $1.0 million as a result of the repayment of debt and interest earned on higher cash balances, an $4.6 million increase in income for affiliated operations as a result of $1.5 million increase in gains from our joint ventures and the absence of $3.1 million in transfer pricing expense with CTCT that were included in the first quarter of fiscal 2005 but now included in operating income and an increase of $0.8 million in foreign currency transaction gain.

Income Tax Provision

Our income tax provision reflects an effective tax rate of 28% for the three months ended March 31, 2006 and 34% for the three months ended April 1, 2005. The 2006 first fiscal quarter tax rate of 28% is lower than the 2005 first fiscal quarter tax rate due to the favorable outcome of an income tax audit which was partially offset by the impact of the accounting for stock based compensation in accordance with SFAS 123R. The fiscal year 2006 tax rate without the favorable outcome of the tax audit approximates 34%, which is the annual estimated effective tax rate that we expect for the balance of FY 2006. The effective tax rate could be affected by stock option activity, geographic mix of our pre-tax income, legislative changes, or changes to our existing valuation allowance or contingent tax liabilities.

Critical Accounting Policies

Stock-based Compensation

We have adopted the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123R, “Share-Based Payment” (“SFAS 123(R)”) using the modified prospective method which requires the adoption of the accounting standard for fiscal periods beginning June 15, 2005. As a result, our financial statements for fiscal periods after December 30, 2005 will include stock-based compensation expenses that are not comparable to financial statements of fiscal periods prior to December 30, 2005. SFAS 123(R) requires stock-based compensation to be estimated using the fair value on the date of grant using an option-pricing model. The value of the portion of the award that is expected to vest is recognized as expense over the requisite service periods of the related employees’ in the Company’s Condensed Consolidated Statement of Income. Prior to the adoption of SFAS 123(R), the Company accounted for stock-based compensation to employees and directors using the intrinsic value method in accordance with APB Opinion No. 25 as allowed under Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”). Under the intrinsic value method, no stock-based compensation expense had been recognized in the Company’s Condensed Consolidated Statement of Income because the exercise price of the Company’s stock options granted to employees and directors equaled the fair market value of the underlying stock at the date of grant.

For options granted prior to October 1, 2005, the fair value for these options was estimated at the date of grant using the Black-Scholes option-pricing model. For stock options granted on or after October 1, 2005, the fair value of each award is estimated on the date of grant using a binomial valuation model. Similar to the Black-Scholes model, the binomial model takes into account variables such as volatility, dividend yield rate, and risk free interest rate. In addition,the binomial model incorporates actual option-pricing behavior and changes in volatility over the option’s contractual term. For these reasons, we believe that the binomial model provides a fair value for stock options that is more representative of actual experience and future expected experience than the value calculated using the Black-Scholes model. The fair value of rights granted under the Employee Stock Purchase Plan is estimated at the date of grant using the Black-Scholes option-pricing model.

For the first quarter of fiscal 2006, we recognized $2.9 million in net stock-based compensation expense. This is compared to the first quarter of fiscal 2005’s pro forma net stock-based compensation expense of $3.1 million. As of March 31, 2006, the total unamortized stock option expense is $18.3 million with a weighted-average recognition period of 1.6 years.

See Note 3 to the Notes to the Condensed Consolidated Financial Statements for additional information.

OFF-BALANCE SHEET FINANCINGS AND LIABILITIES

Other than lease commitments incurred in the normal course of business, we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in the condensed consolidated financial statements. Additionally, we do not have any interest in, or relationship with, any special purpose entities.

LIQUIDITY AND CAPITAL RESOURCES

As of	March 31, 2006	December 30, 2005
(dollars in thousands)
Cash and cash equivalents	$ 97,648	$ 73,853
Accounts receivable days sales outstanding	57	66
Inventory turns per year	4	4
Total debt	$ 603	$ 649
Three Months Ended	March 31, 2006	April 1, 2005
(in thousands)
Net cash provided by (used in) operating activities	$ 16,877	$ (2,135)
Net cash used in investing activities	(7,244)	(14,436)
Net cash used in financing activities	11,100	(4,449)
Net increase (decrease) in cash and cash equivalents	23,795	(21,679)

Cash and Cash Equivalents

Our financial condition further strengthened at March 31, 2006. Cash and cash equivalents totaled $97.6 million compared to $73.9 million at December 30, 2005. We essentially have no debt at March 31, 2006.

* For the first three months of fiscal 2006, cash provided by operating activities was $16.9 million, compared to $2.1 million in cash used in operating activities during the first three months of fiscal 2005. This increase of $19.0 million was driven by a $8.4 million increase in net income and a reduction in inventory of $6.3 million for the first quarter of fiscal 2006 compared to the fourth quarter of fiscal 2005. Our ability to continue to generate cash from operations will depend in large part on profitability, the rate of collections of accounts receivable, our inventory turns, and our ability to manage other areas of working capital. Our accounts receivable days for sales outstanding improved to 57 days at the end of the first quarter of fiscal 2006, from 66 days at the end of fiscal 2005. The decrease is due to increased collection efforts and improvement in monitoring of outstanding receivables. Our inventory turns was unchanged at four for the first three months of fiscal 2006 and at fiscal year end 2005.

Page 24

We used $7.2 million in net cash for investing activities during the first three months of 2006, compared to $14.4 million in the first three months of 2005. The $7.2 million decrease was primarily due to a decrease of $8.9 million in cash used for acquisitions partially offset by an increase of $1.8 million in investment in capital equipment.

* We expect fiscal 2006 capital expenditures to be approximately $15 million to $20 million, primarily for computer equipment, software, manufacturing tools and test equipment, and leasehold improvements associated with business expansion.Decisions related to how much cash is used for investing are influenced by the expected amount of cash to be provided by operations.

We generated $11.1 million in net cash from financing activities in the first three months of 2006, compared to $4.4 million in cash used during the first three months of 2005. The $15.5 million improvement was primarily due to a $10.1 million decrease in repayment of net debt, $3.9 million in excess tax benefits relating to stock-based compensation which was not present in the first quarter of fiscal 2005 and a $1.5 million increase in proceeds received from issuance of common stock.

* We believe that our cash and cash equivalents, together with our credit facilities ($200 million as of March 31, 2006), will be sufficient to meet our anticipated operating cash needs for at least the next twelve months.

Debt

At March 31, 2006, our total debt remained unchanged at approximately $0.6 million compared to the end of fiscal 2005. This relates to government loans to foreign subsidiaries.

On July 28, 2005, we entered into a $200 million unsecured revolving credit agreement (“2005 Credit Facility”) with a syndicate of 10 banks with The Bank of Nova Scotia as the administrative agent. The 2005 Credit Facility replaces our $175 million secured 2003 Credit Facility. The funds available under the new 2005 Credit Facility may be used for our general corporate purposes and up to $25 million of the 2005 Credit Facility may be used for letters of credit. We incur a commitment fee if the 2005 Credit Facility is not used. The commitment fee is not material to our results during all periods presented. At March 31, 2006 and as of the date of this report, the Company has a zero balance outstanding under the 2005 Credit Facility and was in compliance with all financial covenants.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We use certain derivative financial instruments to manage these risks. We do not use derivative financial instruments for speculative or trading purposes. All financial instruments are used in accordance with policies approved by our board of directors.

Market Interest Rate Risk

There has been no change to our market interest rate risk assessment.  Refer to our 2005 Annual Report on Form 10-K.

Foreign Currency Exchange Rate Risk

We enter into foreign exchange forward contracts to minimize the short-term impact of foreign currency fluctuations on certain trade and inter-company receivables and payables, primarily denominated in Australian, Canadian, New Zealand, and Swedish currencies, the Euro, and the British pound. These contracts reduce the exposure to fluctuations in exchange rate movements as the gains and losses associated with foreign currency balances are generally offset with the gains and losses on the forward contracts. These instruments are marked to market through earnings every period and generally range from one to three months in original maturity. We do not enter into foreign exchange forward contract for trading purposes.

Foreign exchange forward contracts outstanding as of March 31, 2006 are summarized as follows (in thousands):

	March 31, 2006
	Nominal Amount		Fair Value
Forward contracts:
Purchased	$	(11,601)	$	(194)
Sold	$	29,603	$	106

* We do not anticipate any material adverse effect on our consolidated financial position utilizing our current hedging strategy.

ITEM 4. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered by this report. Based on such evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company's disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act.

(b) Internal Control Over Financial Reporting.

The Company completed the implementation of a key module of its Enterprise Resource System during the fiscal quarter to which this report relates. The Company evaluated the potential impact to the effectiveness of the Company’s internal control over financial reporting prior to and subsequent to implementation. The Company has concluded that this change does not materially affect or is reasonably like to affect the Company’s internal control over financial reporting.

There were no other changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II.OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, the Company is involved in litigation arising out of the ordinary course of its business. There are no known claims or pending litigation expected to have a material effect on the Company’s overall financial position, results of operations, or liquidity.

ITEM 1A. RISK FACTORS

You should carefully consider the following risk factors, in addition to the other information contained in this Form 10-Q and in any other documents to which we refer you in this Form 10-Q, before purchasing our securities. The risks and uncertainties described below are not the only ones we face.

Our Inability to Accurately Predict Orders and Shipments May Affect Our Revenue, Expenses and Earnings per Share.

We have not been able in the past to consistently predict when our customers will place orders and request shipments so that we cannot always accurately plan our manufacturing requirements. As a result, if orders and shipments differ from what we predict, we may incur additional expenses and build excess inventory, which may require additional reserves and allowances. Any significant change in our customers’ purchasing patterns could have a material adverse effect on our operating results and reported earnings per share for a particular quarter.

Our Operating Results in Each Quarter May Be Affected by Special Conditions, Such As Seasonality, Late Quarter Purchases, Weather, and Other Potential Issues.

Due in part to the buying patterns of our customers, a significant portion of our quarterly revenues occurs from orders received and immediately shipped to customers in the last few weeks and days of each quarter, although our operating expenses tend to remain fairly predictable. Engineering and construction purchases tend to occur in early spring, and governmental agencies tend to utilize funds available at the end of the government’s fiscal year for additional purchases at the end of our third fiscal quarter in September of each year. Concentrations of orders sometimes also occur at the end of our other two fiscal quarters. Additionally, a majority of our sales force earns commissions on a quarterly basis which may cause concentrations of orders at the end of any fiscal quarter. If for any reason expected sales are deferred, orders are not received, or shipments are delayed a few days at the end of a quarter, our operating results and reported earnings per share for that quarter could be significantly impacted.

We Are Dependent on a Specific Manufacturer and Assembler for Many of Our Products and on Specific Suppliers of Critical Parts for Our Products.

We are substantially dependent upon Solectron Corporation in California, China and Mexico as our preferred manufacturing partner for many of our GPS products previously manufactured out of our Sunnyvale facilities. Under the agreement with Solectron, we provide to Solectron a twelve-month product forecast and place purchase orders with Solectron at least thirty calendar days in advance of the scheduled delivery of products to our customers depending on production lead time. Although purchase orders placed with Solectron are cancelable, the terms of the agreement would require us to purchase from Solectron all inventory not returnable or usable by other Solectron customers. Accordingly, if we inaccurately forecast demand for our products, we may be unable to obtain adequate manufacturing capacity from Solectron to meet customers’ delivery requirements or we may accumulate excess inventories, if such inventories are not usable by other Solectron customers. Our current contract with Solectron continues in effect until either party gives the other ninety days written notice.

In addition, we rely on specific suppliers for a number of our critical components. We have experienced shortages of components in the past. Our current reliance on specific or a limited group of suppliers involves several risks, including a potential inability to obtain an adequate supply of required components and reduced control over pricing. Any inability to obtain adequate deliveries or any other circumstance that would require us to seek alternative sources of supply or to manufacture such components internally could significantly delay our ability to ship our products, which could damage relationships with current and prospective customers and could harm our reputation and brand, and could have a material adverse effect on our business.

Page 27

Our Annual and Quarterly Performance May Fluctuate.

Our operating results have fluctuated and can be expected to continue to fluctuate in the future on a quarterly and annual basis as a result of a number of factors, many of which are beyond our control. Results in any period could be affected by:

·   changes in market demand,

·   competitive market conditions,

·   market acceptance of existing or new products,

·   fluctuations in foreign currency exchange rates,

·   the cost and availability of components,

·   our ability to manufacture and ship products,

·   the mix of our customer base and sales channels,

·   the mix of products sold,

·   our ability to expand our sales and marketing organization effectively,

·   our ability to attract and retain key technical and managerial employees,

·   the timing of shipments of products under contracts and

·   general global economic conditions.

In addition, demand for our products in any quarter or year may vary due to the seasonal buying patterns of our customers in the agricultural and engineering and construction industries. Due to the foregoing factors, our operating results in one or more future periods are expected to be subject to significant fluctuations. The price of our common stock could decline substantially in the event such fluctuations result in our financial performance being below the expectations of public market analysts and investors, which are based primarily on historical models that are not necessarily accurate representations of the future.

Our Gross Margin Is Subject to Fluctuation.

Our gross margin is affected by a number of factors, including product mix, product pricing, cost of components, foreign currency exchange rates and manufacturing costs. For example, sales of Nikon-branded products generally have lower gross margins as compared to our GPS survey products. Absent other factors, a shift in sales towards Nikon-branded products would lead to a reduction in our overall gross margins. A decline in gross margin could potentially negatively impact our earnings per share.

Failure to maintain effective internal controls in compliance with Section 404 of the Sarbanes-Oxley Act could have an adverse effect on our business and stock price.

Section 404 of the Sarbanes-Oxley Act requires us to include an internal control report of management in our Annual Report on Form 10-K. For fiscal 2004 and 2005 we satisfied the requirements of Section 404, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent auditors addressing these assessments.

A system of controls, however well designed and operated, cannot provide absolute assurance that the objectives of the system will be met. In addition, the design of a control system is based in part upon certain assumptions about the likelihood of future events. Because of the inherent limitations of control systems, there is only reasonable assurance that our controls will succeed in achieving their stated goals under all potential future conditions.

We Are Dependent on New Products.

Our future revenue stream depends to a large degree on our ability to bring new products to market on a timely basis. We must continue to make significant investments in research and development in order to continue to develop new products, enhance existing products and achieve market acceptance of such products. We may incur problems in the future in innovating and introducing new products. Our development stage products may not be successfully completed or, if developed, may not achieve significant customer acceptance. If we were unable to successfully define, develop and introduce competitive new products, and enhance existing products, our future results of operations would be adversely affected. Development and manufacturing schedules for technology products are difficult to predict, and we might not achieve timely initial customer shipments of new products. The timely availability of these products in volume and their acceptance by customers are important to our future success. A delay in new product introductions could have a significant impact on our results of operations.

Page 28

We Are Dependent on Proprietary Technology.

Our future success and competitive position is dependent upon our proprietary technology, and we rely on patent, trade secret, trademark and copyright law to protect our intellectual property. The patents owned or licensed by us may be invalidated, circumvented, and challenged. The rights granted under these patents may not provide competitive advantages to us. Any of our pending or future patent applications may not be issued within the scope of the claims sought by us, if at all.

Others may develop technologies that are similar or superior to our technology, duplicate our technology or design around the patents owned by us. In addition, effective copyright, patent and trade secret protection may be unavailable, limited or not applied for in certain countries. The steps taken by us to protect our technology might not prevent the misappropriation of such technology.

The value of our products relies substantially on our technical innovation in fields in which there are many current patent filings. We recognize that as new patents are issued or are brought to our attention by the holders of such patents, it may be necessary for us to withdraw products from the market, take a license from such patent holders, or redesign our products. We do not believe any of our products currently infringe patents or other proprietary rights of third parties, but we cannot be certain they do not do so. In addition, the legal costs and engineering time required to safeguard intellectual property or to defend against litigation could become a significant expense of operations. Such events could have a material adverse effect on our revenues or profitability.

Our products may contain errors or defects, which could result in damage to our reputation, lost revenues, diverted development resources and increased service costs, warranty claims and litigation.

Our devices are complex and must meet stringent requirements. We warrant that our products will be free of defect for various periods of time, depending on the product. In addition, certain of our contracts include epidemic failure clauses. If invoked, these clauses may entitle the customer to return or obtain credits for products and inventory, or to cancel outstanding purchase orders even if the products themselves are not defective.

We must develop our products quickly to keep pace with the rapidly changing market, and we have a history of frequently introducing new products. Products and services as sophisticated as ours could contain undetected errors or defects, especially when first introduced or when new models or versions are released. In general, our products may not be free from errors or defects after commercial shipments have begun, which could result in damage to our reputation, lost revenues, diverted development resources, increased customer service and support costs and warranty claims and litigation which could harm our business, results of operations and financial condition.

We Are Dependent on the Availability of Allocated Bands within the Radio Frequency Spectrum.

Our GPS technology is dependent on the use of the Standard Positioning Service (“SPS”) provided by the US Government’s GPS. The GPS SPS operates in radio frequency bands that are globally allocated for radio navigation satellite services. International allocations of radio frequency are made by the International Telecommunications Union (“ITU”), a specialized technical agency of the United Nations. These allocations are further governed by radio regulations that have treaty status and which may be subject to modification every two to three years by the World Radio Communication Conference.

Any ITU reallocation of radio frequency bands, including frequency band segmentation or sharing of spectrum, may materially and adversely affect the utility and reliability of our products. Many of our products use other radio frequency bands, together with the GPS signal, to provide enhanced GPS capabilities, such as real-time kinematic precision. The continuing availability of these non-GPS radio frequencies is essential to provide enhanced GPS products to our precision survey and construction machine controls markets. Any regulatory changes in spectrum allocation or in allowable operating conditions may cause a material adverse effect on our operating results.

In addition, unwanted emissions from mobile satellite services and other equipment operating in adjacent frequency bands or in-band from licensed and unlicensed devices may materially and adversely affect the utility and reliability of our products. The FCC continually receives proposals for novel technologies and services, such as ultra-wideband technologies, which may seek to operate in, or across, the radio frequency bands currently used by the GPS SPS and other public safety services. Adverse decisions by the FCC that result in harmful interference to the delivery of the GPS SPS and other radio frequency spectrum also used in our products may result in a material adverse effect on our business and financial condition.

Page 29

Many of Our Products Rely on the GPS Satellite System.

The GPS satellites and their ground support systems are complex electronic systems subject to electronic and mechanical failures and possible sabotage. The satellites currently in orbit were originally designed to have lives of 7.5 years and are subject to damage by the hostile space environment in which they operate. However, of the current deployment of 29 satellites in place, some have already been in operation for 12 years. To repair damaged or malfunctioning satellites is currently not economically feasible. If a significant number of satellites were to become inoperable, there could be a substantial delay before they are replaced with new satellites. A reduction in the number of operating satellites may impair the current utility of the GPS system and the growth of current and additional market opportunities.

In 2004, a Presidential policy affirmed a 1996 Presidential Decision Directive that marked the first time in the evolution of GPS that access for civilian use free of direct user fees. In addition, Presidential policy has been complemented by corresponding legislation, that was signed into law. However, there can be no assurance that the US Government will remain committed to the operation and maintenance of GPS satellites over a long period, or that the policies of the US Government for the use of GPS without charge will remain unchanged. Because of ever-increasing commercial applications of GPS, other US Government agencies may become involved in the administration or the regulation of the use of GPS signals. Any of the foregoing factors could affect the willingness of buyers of our products to select GPS-based systems instead of products based on competing technologies.

Many of our products also use signals from systems that augment GPS, such as the Wide Area Augmentation System (WAAS) and National Differential GPS System (NDGPS). Many of these augmentation systems are operated by the federal government and rely on continued funding and maintenance of these systems. In addition, some of our products also use satellite signals from the Russian Glonass System. Any curtailment of the operating capability of these systems could result in decreased user capability thereby impacting our markets.

The European governments have begun development of an independent satellite navigation system, known as Galileo. We have access to the preliminary signal design, which is subject to change. Although an operational Galileo system is several years away, if we are unable to timely develop a commercial product, it may have a materially adverse effect on our business and operating results.

We may be Materially Affected by New Regulatory Requirements.

We are subject to various federal, state and local environmental laws and regulations that govern our operations, including the handling and disposal of non-hazardous and hazardous wastes, and emissions and discharges into the environment. Failure to comply with such laws and regulations could result in costs for corrective action, penalties, or the imposition of other liabilities.

In particular, under certain of these laws and regulations, a current or previous owner or operator of property may be liable for the costs of remediating hazardous substances or petroleum products on or from its property, without regard to whether the owner or operator knew of, or caused, the contamination, as well as incur liability to third parties impacted by such contamination. In addition, we face increasing complexity in our product design and procurement operations as we adjust to new and upcoming requirements relating to the materials composition of many of our products. The European Union (“EU”) has adopted new directives to facilitate the recycling of electrical and electronic equipment sold in the EU. One of these is the Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) directive. The RoHS directive restricts the use of lead, mercury and certain other substances in electrical and electronic products placed on the market in the European Union after July 1, 2006.

Similar laws and regulations have been or may be enacted in other regions, including in the United States, China and Japan. Other environmental regulations may require us to reengineer our products to utilize components which are more environmentally compatible and such reengineering and component substitution may result in additional costs to us. Although we do not anticipate any material adverse effects based on the nature of our operations and the effect of such laws, there is no assurance that such existing laws or future laws will not have a material adverse effect on our business.

Our Business is Subject to Disruptions and Uncertainties Caused by War or Terrorism.

Acts of war or acts of terrorism could have a material adverse impact on our business, operating results, and financial condition. The threat of terrorism and war and heightened security and military response to this threat, or any future acts of terrorism, may cause further disruption to our economy and create further uncertainties. To the extent that such disruptions or uncertainties result in delays or cancellations of orders, or the manufacture or shipment of our products, our business, operating results, and financial condition could be materially and adversely affected.

Page 30

We Are Exposed to Fluctuations in Currency Exchange Rates.

A significant portion of our business is conducted outside the US, and as such, we face exposure to movements in non-US currency exchange rates. These exposures may change over time as business practices evolve and could have a material adverse impact on our financial results and cash flows. Fluctuation in currency impacts our operating results.

Currently, we hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. The hedging activities undertaken by us are intended to offset the impact of currency fluctuations on certain non-functional currency assets and liabilities. Our attempts to hedge against these risks may not be successful resulting in an adverse impact on our net income.

We Face Risks in Investing in and Integrating New Acquisitions.

We have recently acquired several companies and may in the future acquire other companies. Acquisitions of companies, divisions of companies, or products entail numerous risks, including:

·   potential inability to successfully integrate acquired operations and products or to realize cost savings or other anticipated benefits from integration;

·   diversion of management’s attention;

·   loss of key employees of acquired operations;

·   the difficulty of assimilating geographically dispersed operations and personnel of the acquired companies;

·   the potential disruption of our ongoing business;

·   unanticipated expenses related to such integration;

·   the correct assessment of the relative percentages of in-process research and development expense that can be immediately written off as compared to the amount which must be amortized over the appropriate life of the asset;

·   the impairment of relationships with employees and customers of either an acquired company or our own business;

·   the potential unknown liabilities associated with acquired business; and

·   inability to recover strategic investments in development stage entities.

As a result of such acquisitions, we have significant assets that include goodwill and other purchased intangibles. The testing of these intangibles under established accounting guidelines for impairment requires significant use of judgment and assumptions. Changes in business conditions could require adjustments to the valuation of these assets. In addition, losses incurred by a company in which we have an investment may have a direct impact on our financial statements or could result in our having to write-down the value of such investment. Any such problems in integration or adjustments to the value of the assets acquired could harm our growth strategy and have a material adverse effect on our business, financial condition and compliance with debt covenants.

We May Not Be Able to Enter Into or Maintain Important Alliances.

We believe that in certain business opportunities our success will depend on our ability to form and maintain alliances with industry participants, such as Caterpillar, Nikon, and CNH Global. Our failure to form and maintain such alliances, or the pre-emption of such alliances by actions of other competitors or us, will adversely affect our ability to penetrate emerging markets. No assurances can be given that we will not experience problems from current or future alliances or that we will realize value from any such strategic alliances.

We Face Competition in Our Markets.

Our markets are highly competitive and we expect that both direct and indirect competition will increase in the future. Our overall competitive position depends on a number of factors including the price, quality and performance of our products, the level of customer service, the development of new technology and our ability to participate in emerging markets. Within each of our markets, we encounter direct competition from other GPS, optical and laser suppliers and competition may intensify from various larger US and non-US competitors and new market entrants, some of which may be our current customers. The competition in the future may, in some cases, result in price reductions, reduced margins or loss of market share, any of which could materially and adversely affect our business, operating results and financial condition. We believe that our ability to compete successfully in the future against existing and additional competitors will depend largely on our ability to execute our strategy to provide systems and products with significantly differentiated features compared to currently available products. We may not be able to implement this strategy successfully, and our products may not be competitive with other technologies or products that may be developed by our competitors, many of whom have significantly greater financial, technical, manufacturing, marketing, sales and other resources than we do.

Page 31

We Must Carefully Manage Our Future Growth.

Growth in our sales or continued expansion in the scope of our operations could strain our current management, financial, manufacturing and other resources, and may require us to implement and improve a variety of operating, financial and other systems, procedures, and controls. We have recently implemented a new enterprise resource planning software system and we may experience in our financial and order management processing as a result of new procedures. Problems associated with any improvement or expansion of these systems, procedures or controls may adversely affect our operations and these systems, procedures or controls may not be designed, implemented or improved in a cost-effective and timely manner. Any failure to implement, improve and expand such systems, procedures, and controls in a timely and efficient manner could harm our growth strategy and adversely affect our financial condition and ability to achieve our business objectives.

We Are Dependent on Retaining and Attracting Highly Skilled Development and Managerial Personnel.

Our ability to maintain our competitive technological position will depend, in a large part, on our ability to attract, motivate, and retain highly qualified development and managerial personnel. Competition for qualified employees in our industry and locations is intense, and there can be no assurance that we will be able to attract, motivate, and retain enough qualified employees necessary for the future continued development of our business and products.

We Are Subject to the Impact of Governmental and Other Similar Certifications.

We market certain products that are subject to governmental and similar certifications before they can be sold. For example, CE certification for radiated emissions is required for most GPS receiver and data communications products sold in the European Union. An inability to obtain such certifications in a timely manner could have an adverse effect on our operating results. Also, some of our products that use integrated radio communication technology require an end user to obtain licensing from the Federal Communications Commission (FCC) for frequency-band usage. These are secondary licenses that are subject to certain restrictions. An inability or delay in obtaining such certifications or changes to the rules by the FCC could adversely affect our ability to bring our products to market which could harm our customer relationships and have a material adverse effect on our business.

We Are Subject to the Adverse Impact of Radio Frequency Congestion.

We have certain products, such as GPS RTK systems, and surveying and mapping systems that use integrated radio communication technology requiring access to available radio frequencies allocated by the FCC (or the NTIA in the case of federal government users of this equipment) for which the end user is required to obtain a license in order to operate their equipment. In addition, access to these frequencies by state agencies is under management by state radio communications coordinators. Some bands are experiencing congestion that excludes their availability for access by state agencies in some states. To reduce congestion, the FCC announced that it will require migration of radio technology from wideband to narrowband operations in these bands. The rules require migration of users to narrowband channels by 2011. In the meantime congestion could cause FCC coordinators to restrict or refuse licenses. An inability to obtain access to these radio frequencies by end users could have an adverse effect on our operating results.

The Volatility of Our Stock Price Could Adversely Affect Your Investment in Our Common Stock.

The market price of our common stock has been, and may continue to be, highly volatile. During the first fiscal quarter of 2006, our stock price ranged from $45.05 to $35.02. We believe that a variety of factors could cause the price of our common stock to fluctuate, perhaps substantially, including:

·   announcements and rumors of developments related to our business or the industry in which we compete;

·   quarterly fluctuations in our actual or anticipated operating results and order levels;

·   general conditions in the worldwide economy, including fluctuations in interest rates;

·   announcements of technological innovations;

·   new products or product enhancements by us or our competitors;

·   developments in patents or other intellectual property rights and litigation;

·   developments in our relationships with our customers and suppliers; and

·   any significant acts of terrorism against the United States.

Page 32

In addition, in recent years the stock market in general and the markets for shares of "high-tech" companies in particular, have experienced extreme price fluctuations which have often been unrelated to the operating performance of affected companies. Any such fluctuations in the future could adversely affect the market price of our common stock, and the market price of our common stock may decline.

Provisions in Our Charter Documents and Under California Law Could Prevent or Delay a Change of Control, which Could Reduce the Market Price of Our Common Stock.

Certain provisions of our articles of incorporation, as amended and restated, our bylaws, as amended and restated, and the California General Corporation Law may be deemed to have an anti-takeover effect and could discourage a third party from acquiring, or make it more difficult for a third party to acquire, control of us without approval of our board of directors. These provisions could also limit the price that certain investors might be willing to pay in the future for shares of our common stock. Certain provisions allow the board of directors to authorize the issuance of preferred stock with rights superior to those of the common stock.

We have adopted a Preferred Shares Rights Agreement, commonly known as a "poison pill." The provisions described above, our poison pill and provisions of the California General Corporation Law may discourage, delay or prevent a third party from acquiring us.
