B. Accounting Policies

Basis of Presentation

The condensed consolidated interim financial statements include the accounts of Teradyne and its subsidiaries. All significant intercompany balances and transactions have been eliminated. These financial statements reflect all normal recurring adjustments which are, in the opinion of management, necessary for the fair presentation of such interim financial statements. Certain prior years’ amounts were reclassified to conform to the current year presentation. The year-end condensed consolidated balance sheet data were derived from audited financial statements, but do not include all disclosures required by generally accepted accounting principles.

The accompanying financial information should be read in conjunction with the consolidated financial statements and notes thereto contained in Teradyne’s Annual Report on Form 10-K, filed with the United States Securities and Exchange Commission on March 15, 2004 for the year ended December 31, 2003.

Preparation of Financial Statements

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the amounts reported in the financial statements. Actual results may differ significantly from these estimates.

In the first quarter of 2003, Assembly Test Systems sold its manufacturing software product line and manual x-ray inspection and rework product line for total cash proceeds of $2.1 million. These transactions resulted in a loss of $5.8 million, which has been recorded in restructuring and other charges for the nine months ended September 28, 2003. Included in the $5.8 million loss is an intangible asset impairment charge of $3.7 million.

Aggregate amortization expense for the three months ended October 3, 2004 and September 28, 2003 was $0.9 million and $1.0 million, respectively. Aggregate amortization expense for the nine months ended October 3, 2004 and September 28, 2003 was $2.7 million and $3.5 million, respectively.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The computation of diluted income per common share for the three and nine months ended October 3, 2004 excludes the effect of the potential exercise of options to purchase approximately 28.9 million and 23.0 million shares, respectively, because the option price was greater than the average market price of the common shares and the effect would have been anti-dilutive. All options and equivalent shares related to the convertible notes outstanding in the three and nine months ended September 28, 2003 were excluded from the calculation of diluted net loss per share because the effect would have been anti-dilutive. As of October 3, 2004 and September 28, 2003 there were 34.6 million and 31.1 million options outstanding, respectively.

The effect of Teradyne’s outstanding convertible notes on diluted net income per share for the nine months ended October 3, 2004 was calculated using the “if converted” method as required by SFAS No. 128, “Earnings per Share” (“SFAS 128”). In using the “if converted” method, interest expense related to the convertible notes is added back to net income to arrive at diluted net income, and the incremental shares from the assumed conversion are included in diluted shares outstanding. For the computation of diluted net income per share for the nine months ended October 3, 2004, $11.1 million of net interest expense related to the convertible notes was added back to net income to arrive at diluted net income. In the three months ended October 3, 2004, 15.1 million shares related to the convertible notes outstanding have been excluded from the diluted shares outstanding, as their inclusion in the calculation would have been anti-dilutive.

E. Treasury Stock

Effective July 1, 2004, the Massachusetts Business Corporation Act was revised to eliminate the use of treasury shares by Massachusetts corporations. As a result, all of Teradyne’s treasury shares were automatically converted to unissued shares on July 1, 2004.

F. Restructuring and Other Charges

The tables below represent activity related to restructuring charges in the three and nine months ended October 3, 2004 and September 28, 2003. The accrual for severance and benefits is reflected in accrued employees’ compensation and withholdings. The accrual for lease payments on vacated facilities is reflected in other accrued liabilities and other long-term accrued liabilities and is expected to be paid out over the lease terms, the latest of which expires in 2012. Teradyne expects to pay out approximately $6 million against the lease accruals over the next twelve months. Teradyne’s future lease commitments are net of expected sublease income of $13 million as of October 3, 2004. Teradyne has subleased approximately 23% of its unoccupied space as of October 3, 2004 and is actively attempting to sublease the remaining space.

to the extent that such contributions are tax deductible. In addition, Teradyne has an unfunded supplemental executive defined benefit plan in the United States to provide retirement benefits in excess of levels allowed by the Employment Retirement Income Security Act and the Internal Revenue Code.

J. Segment Information

Teradyne has four principal reportable segments which include the design, manufacturing and marketing of Semiconductor Test Systems, Connection Systems, Assembly Test Systems, and Other Test Systems. These reportable segments were determined based upon the nature of the products and services offered by each. The Other Test Systems segment is comprised of Broadband Test Systems and Diagnostic Solutions.

Teradyne evaluates performance based on several factors, of which the primary financial measure is business segment income before taxes. The accounting policies of the business segments are the same as those described in Note B: “Accounting Policies” in Teradyne’s Annual Report on Form 10-K for the year ended December 31, 2003. Intersegment sales are accounted for at fair value as if sales were made to third parties. Segment information for the three and nine months ended October 3, 2004 and September 28, 2003 is as follows (in thousands):

K. Commitments and Contingencies

After the August 2000 acquisition of Herco Technology Corp. and Perception Laminates, Inc. the former owners of those companies filed a complaint on September 5, 2001 against Teradyne and two of its executive officers. The case is now pending in Federal District Court, in San Diego, California. Teradyne and the two individual defendants filed a motion to dismiss the complaint in its entirety. The court granted the motion in part, and the only remaining claims were that the sale of Teradyne’s common stock to the former owners violated certain California securities statutes and common law and that Teradyne breached certain contractual obligations in the agreements relating to the acquisitions. Teradyne’s subsequent motion for partial summary judgment with respect to the breach of contract claims was granted on November 7, 2002. On December 9, 2002, the plaintiffs filed a motion asking the court to reconsider its summary judgment ruling or, alternatively, for certification under Rule 54(b) which would grant the plaintiffs leave to appeal both the Court’s ruling regarding dismissal of claims and its ruling granting summary judgment to the Ninth Circuit Court of Appeals. Teradyne opposed these motions. On April 22, 2003, the Court denied the plaintiffs’ motion for reconsideration and the plaintiffs’ request for certification under Rule 54(b). The only claim still pending before the District Court from the original complaint relates to fraud in connection with the setting of the transaction price. Teradyne has answered and denied all liability.

Teradyne and two of its executive officers were named as defendants in three purported class action complaints that were filed in Federal District Court, Boston, Massachusetts, in October and November 2001. The court consolidated the cases and has appointed three lead plaintiffs. On November 8, 2002, plaintiffs filed and served a consolidated amended class action complaint. The complaint alleges, among other things, that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by making, during the period from July 14, 2000 until October 17, 2000, material misrepresentations and omissions to the investing public regarding Teradyne’s business operations and future prospects. The complaint seeks unspecified damages, including compensatory damages and recovery of reasonable attorneys’ fees and costs. Teradyne filed a motion to dismiss all claims asserted in the complaint on February 7, 2003. On January 16, 2004, the U.S. Magistrate Judge recommended to the U.S. District Court that Teradyne’s motion to dismiss the consolidated amended class action complaint in its entirety be allowed without prejudice. On February 2, 2004, the lead plaintiffs filed an objection to the U.S. Magistrate Judge’s recommendation. Teradyne filed its response to the lead plaintiff’s objection on March 2, 2004. On September 8, 2004, the U.S. District Court adopted the U.S. Magistrate Judge’s recommendation and dismissed the consolidated amended class action complaint in its entirety without prejudice.

In 2001, Teradyne was designated as a “potentially responsible party” (“PRP”) at a clean-up site in Los Angeles, California. This claim arises out of Teradyne’s acquisition of Perception Laminates, Inc. in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an

18

TERADYNE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

asset purchase agreement dated July 30, 1992. Neither Teradyne nor Perception Laminates have ever conducted any operations at the Los Angeles site. Teradyne has asked the State of California to drop the PRP designation, but California has not yet agreed to do so.

On April 30, 2004, Hampshire Equity Partners II, LP (“HEP”) filed a complaint against Teradyne and Teradyne’s Connection Systems segment (“TCS”) in the United States District Court of the Southern District of New York, relating to its February 21, 2001 investment of $55.0 million in Connector Service Corporation, aka AMAX Plating, Inc. (“CSC”), which was a supplier to TCS at the time. During the due diligence that HEP conducted prior to making that investment, an agent of HEP spoke with TCS, among other CSC customers, concerning CSC. On or about September 24, 2003, CSC filed for bankruptcy protection. HEP has now brought suit against Teradyne and TCS asserting fraud and negligence based claims, and a claim for intentional interference with economic opportunity, relating to statements that a TCS representative made to HEP’s agent prior to HEP’s February 2001 investment in CSC. HEP seeks to hold Teradyne and TCS responsible for its decision to invest in CSC and for the losses that it suffered upon the bankruptcy of CSC. HEP is now seeking damages for an unstated amount of not less than $55.0 million. On June 17, 2004, Teradyne and TCS filed a motion to dismiss HEP’s complaint in its entirety. On August 9, 2004, HEP filed its opposition to the motion to dismiss, and Teradyne filed its reply brief on September 22, 2004. Teradyne’s motion to dismiss remains pending.

Teradyne believes that it has meritorious defenses against the above unsettled claims and intends to vigorously contest them. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, Teradyne believes the losses associated with all of these actions will not have a material adverse effect on its consolidated financial position or liquidity, but could possibly be material to the consolidated results of operations of any one period.

In addition, Teradyne is subject to legal proceedings, claims and investigations that arise in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Although there can be no assurance, there are no such matters pending that Teradyne expects to be material with respect to its business, financial position or results of operations.

Results of Operations

Third Quarter 2004 Compared to Third Quarter 2003

Bookings

Net bookings for our four principal reportable segments were as follows (in millions, except percent change):

	For the Three Months Ended				% Change
	October 3, 2004		September 28, 2003
Semiconductor Test Systems	$	128.3	$	187.4	(31.5	)%
Connection Systems		97.4		95.1	2.4
Assembly Test Systems		38.0		37.6	1.1
Other Test Systems		20.4		16.2	25.9
	$	284.1	$	336.3	(15.5	)%

The Semiconductor Test Systems decrease in orders was primarily driven by excess inventory levels at a number of our customers.

The nominal overall growth in Connection Systems orders was primarily led by stronger customer demand in the wireless market segment.

The nominal overall increase in orders in Assembly Test Systems was attributable to a strong increase in commercial products and services, offset in large part by a decrease in our military/aerospace (“mil/aero”) business. Orders were also lower due to the sale of the manual X-ray, rework, and AOI product lines in the fourth quarter of 2003.

The increase in Other Test Systems’ orders resulted from an increase in Broadband Test Systems, while Diagnostic Systems bookings remained relatively flat year-over-year. Other Test Systems’ bookings are program related and have significant fluctuations.

Cancellations and backlog adjustments for our four principal reportable segments were as follows (in millions):

	For the Three Months Ended
	October 3, 2004		September 28, 2003
Semiconductor Test Systems	$	10.5	$	0.2
Connection Systems		—		0.2
Assembly Test Systems		—		0.3
Other Test Systems		—		—
	$	10.5	$	0.7

Semiconductor Test Systems experienced $10.5 million of cancellations and backlog adjustments in the three months ended October 3, 2004. Approximately 50% of this amount was related to cancellations, while the remainder was a backlog adjustment driven by management’s estimate of what may be cancelled in future periods based on current information.

21

Customers may delay delivery of products or cancel orders suddenly and without significant notice, subject to possible cancellation penalties. In the third quarter of 2004 and 2003, there were no significant cancellation penalties received. Due to possible changes in delivery schedules and cancellations of orders, our backlog at any particular date is not necessarily indicative of the actual sales for any succeeding period. Delays in delivery schedules and/or cancellations of backlog during any particular period could have a materially adverse effect on our business, financial condition and results of operations.

Revenue

Net revenues for our four principal reportable segments were as follows (in millions, except percent changes):

	For the Three Months Ended				% Change
	October 3, 2004		September 28, 2003
Semiconductor Test Systems	$	298.3	$	188.2	58.5	%

Other Test Systems		25.1		22.4	12.1
	$	457.8	$	329.2	39.1	%

Semiconductor Test Systems revenue made up 65.1% of total revenue for the third quarter of 2004, up from 57.2% a year ago, led by sales of our Catalyst and Flex systems. The increase in sales was led by the broadband market, but was also affected by sales in the wireless and mass storage/datacom markets as well. The improvement in the Asian markets is the most dominant factor in attributing growth by geographic region.

22

The growth in Connection Systems revenues was led by strong customer demand in the wireless market segment, mainly attributable to our connector business.

The increase in Assembly Test Systems sales was due primarily to an increase in the mil/aero business, offset, in part, by a nominal decrease in commercial products and services. The increase in mil/aero revenue was the result of earlier wins of large multi-year programs.

Our sales by region as a percentage of total net sales were as follows:

Gross Margin

Our gross profit was as follows (dollars in millions):

	For the Three Months Ended						Period Change
	October 3, 2004			September 28, 2003
Gross Profit	$	188.5		$	98.6		$	89.9
Percent of Total Revenue		41.2	%		29.9	%

The gross margin improvement from the third quarter of 2003 to 2004 was a result of several factors. An improvement of 10 points is credited to an increase in sales volume and a shift in our mix of revenues, with higher Semiconductor Test Systems content. The remainder is attributable to lower material costs and a reduction in fixed manufacturing costs, including depreciation and facility costs resulting from past restructuring actions.

We assess the carrying value of our inventory on a quarterly basis by estimating future demand and comparing that demand against on-hand and on-order inventory provisions. Forecasted revenue information is obtained from the sales and marketing groups and incorporates factors such as backlog and future revenue demand. This quarterly process identifies obsolete and excess inventory. Obsolete inventory, which represents items for which there is no demand, is fully reserved. Excess inventory, which represents inventory items that are not expected to be consumed during the next four quarters, is written down to estimated net realizable value.

The provisions for excess and obsolete inventory were $2.5 million and $3.5 million for the three months ended October 3, 2004 and September 28, 2003, respectively. During the three months ended October 3, 2004, we scrapped $4.4 million of inventory and sold $0.2 million of previously written-down or written-off inventory. As of October 3, 2004, we have inventory related reserves for amounts which had been written-down or written-off of $168.7 million. We have no pre-determined timeline to scrap the remaining inventory.

23

Engineering and Development

Engineering and development expenses were as follows (dollars in millions):

	For the Three Months Ended						Period Change
	October 3, 2004			September 28, 2003
Engineering and Development	$	67.2		$	61.2		$	6.0
Percent of Total Revenue		14.7	%		18.6	%

The increase of $6 million in engineering and development expenses is primarily the result of our strong commitment to sustained levels of investment in product research and development offset by the results of on-going actions to reduce fixed costs. The increase can be attributed to the following:

• $3 million increase due to variable employee compensation;

• $3 million increase in prototype material for engineering development projects; and

• $2 million from an increase in outsourced contract engineering.

These increases were offset in part by the following:

• $1 million net decrease for the salaries and fringe benefits due to a decrease in headcount partially offset by salary increases effective July 1, 2004; and

• $1 million in lower depreciation as a result of lower capital spending, asset write-downs and facility closures.

Selling and Administrative

Selling and administrative expenses were as follows (dollars in millions):

	For the Three Months Ended						Period Change
	October 3, 2004			September 28, 2003
Selling and Administrative	$	70.3		$	60.1		$	10.2
Percent of Total Revenue		15.3	%		18.2	%

The increase of $10 million in selling and administrative spending is due primarily to the following:

• $5 million increase due to variable employee compensation;

• $4 million from an increase in consulting expenses; and

• $2 million increase in salaries and fringe benefits due to salary increases effective July, 1 2004.

These increases were offset in part by the following:

• $1 million in lower depreciation costs due to asset write-downs and capital spending cutbacks.

Restructuring and Other Charges

The tables below represent activity related to restructuring charges for the three months ended October 3, 2004 and September 28, 2003. The accrual for severance and benefits is reflected in accrued employees’ compensation and withholdings. The accrual for lease payments on vacated facilities is reflected in other accrued liabilities and other long-term accrued liabilities and is expected to be paid out over the lease terms, the latest of

24

which expires in 2012. Teradyne expects to pay out approximately $6 million against the lease accruals over the next twelve months. Teradyne’s future lease commitments are net of expected sublease income of $13 million as of October 3, 2004. Teradyne has subleased approximately 23% of its unoccupied space as of October 3, 2004 and is actively attempting to sublease the remaining space.

The table below summarizes the liability and activity for the three months ended October 3, 2004 relating to restructuring and other charges (in thousands):

	Long-Lived Asset Impairment			Severance and Benefits			Facility Related			Other Charges			Total
Balance at July 4, 2004	$	—		$	2,264		$	23,400		$	1,157		$	26,821

Balance at October 3, 2004	$	—		$	1,580		$	21,689		$	710		$	23,979

During the three months ended October 3, 2004, Teradyne recorded the following activity related to restructuring and other charges:

• $0.6 million charge primarily for certain long-lived assets that were impaired as the estimated value of such assets was less than the carrying value. These charges pertain to the impairment of leasehold improvements in facilities vacated in the Assembly Test Systems segment.

• $0.1 million charge for severance and related benefits. There were approximately 12 employees terminated in the three months ended October 3, 2004 across Teradyne. As of October 3, 2004, $1.6 million in severance and benefits remains unpaid and is included in accrued employees’ compensation and withholdings.

• $0.7 million reversal of other charges for amounts earned under agreements related to the sale of product lines in prior reporting periods in the Assembly Test and Other Test Systems segments.

The table below summarizes the liability and activity for the three months ended September 28, 2003, relating to restructuring and other charges (in thousands):

	Long-Lived Asset Impairment			Severance and Benefits			Other Charges		Facility Related			Total
Balance at June 29, 2003	$	—		$	7,976		$	—	$	24,281		$	32,257

Balance at September 28, 2003	$	—		$	12,441		$	1,795	$	22,011		$	36,247

During the three months ended September 28, 2003, Teradyne recorded the following activity related to restructuring and other charges:

• $11.4 million of charges, consisting of $11.2 million primarily related to the sale and leaseback of certain manufacturing assets in the Connection Systems segment, and $0.2 million related to the impairment of manufacturing assets held for sale in the Assembly Test Systems segment.

• $10.2 million charge related to severance and related benefits. There were approximately 340 employees terminated in the third quarter of 2003 across Teradyne.

• $1.8 million charge primarily for contractual penalties associated with resizing the Connections Systems segment.

25

Interest Income and Expense

Interest income increased to $3.8 million for the third quarter of 2004 from $3.5 million in the third quarter of 2003 due to an overall increase in Teradyne’s cash and marketable securities balance. Interest expense decreased to $4.7 million in the third quarter of 2004 from $5.5 million in the third quarter of 2003 as a result of the prepayment of our mortgage for our California properties in the third quarter of 2003.

Other Income and Expense, Net

Other income and expense, net for the three months ended October 3, 2004 and September 28, 2003, respectively, includes the following (in thousands):

	For the three months ended
	October 3, 2004		September 28, 2003
Mortgage prepayment penalty (1)	$	—	$	(3,220	)
Fair value adjustment on warrants		—		(12	)
Total		—	$	(3,232	)

(1) Penalties related to the prepayment of a $45 million mortgage loan collateralized against certain California real estate properties, which was to mature on January 1, 2007.

Income Taxes

As a result of incurring significant operating losses from 2001 through 2003, we determined that it was more likely than not that our deferred tax assets may not be realized, and since the fourth quarter of 2002 we established a full valuation allowance for our net deferred tax assets. If we generate sustained future taxable income against which these tax attributes may be applied, some portion or all of the valuation allowance would be reversed. If the valuation allowance were reversed, a portion would be recorded as an increase to additional paid in capital, and the remainder would be recorded as a reduction to income tax expense. Similar to prior periods, the tax expense in the third quarter of 2004 is composed of amounts recorded for foreign taxes, however, it also includes an IRS settlement of $3.0 million related to the closing out of tax years 1999 through 2001, and an adjustment to our estimated annual tax rate from 10% to 10.5%. The tax expense for 2003 relates primarily to a tax provision for foreign taxes, and was recorded using an effective tax rate of 4%.

Nine Months of 2004 Compared to Nine Months of 2003

Bookings

Net bookings for our four principal reportable segments were as follows (in millions, except percent change):

	For the Nine Months Ended				Percent Change
	October 3, 2004		September 28, 2003
Semiconductor Test Systems	$	887.5	$	525.7	68.8	%
Connection Systems		308.1		230.6	33.6
Assembly Test Systems		115.2		108.6	6.1
Other Test Systems		82.4		65.0	26.8
	$	1,393.2	$	929.9	49.8	%

26

As total Semiconductor Test Systems orders increased from the first nine months of 2003 to the first nine months of 2004, Semiconductor Test’s percentage of total bookings grew as well, increasing from 56.5% of total bookings in the first nine months of 2003 to 63.7% for the first nine months of 2004. The growth in orders was spread across all products, but was primarily due to increased orders of our Flex and Catalyst products, and encompassed all geographic markets. This growth was spurred by higher demand from a variety of end-users, including the wireless, broadband and mass storage/datacom markets.

The growth in Connection Systems orders was led by stronger customer demand in the wireless market segment across both connector and backplane assembly products. New product growth accounted for approximately 22% of the growth in the connector business. This growth was partially offset by a decline in orders due to the decision to exit the lower margin portion of Connection Systems’ EMS business.

Orders in Assembly Test Systems increased in the mil/aero business, offset by a decline in commercial products and systems primarily due to the sale of the manual X-ray, rework and AOI product lines in 2003, resulting in an overall increase in bookings year over year.

Other Test Systems’ order growth resulted from an increase in Broadband Test Systems bookings, primarily a result of the timing of significant hardware orders for voice line test services in the first nine months of 2004, offset by a decrease in orders in Diagnostic Solutions. Other Test Systems’ bookings are program related and have significant fluctuations.

Cancellations for our four principal reportable segments were as follows (in millions):

	For the Nine Months Ended
	October 3, 2004		September 28, 2003
Semiconductor Test Systems	$	10.5	$	6.8
Connection Systems		—		16.0
Assembly Test Systems		0.2		0.7
Other Test Systems		—		0.1
	$	10.7	$	23.6

Semiconductor Test Systems experienced $10.5 million of cancellations and backlog adjustments in the nine months ended October 3, 2004. Approximately 50% of this amount was related to cancellations, while the remainder was a backlog adjustment driven by management’s estimate of what may be canceled in future periods.

The Connection Systems cancellations in the first nine months of 2003 were from major customers in the telecommunications and networking infrastructure industries, due principally to product program cancellations. Customers may delay delivery of products or cancel orders suddenly and without significant notice, subject to possible cancellation penalties. In the first nine months of 2004 and 2003 there were no significant cancellation penalties received. Due to possible changes in delivery schedules and cancellations of orders, our backlog at any particular date is not necessarily indicative of the actual sales for any succeeding period. Delays in delivery schedules and/or cancellations of backlog during any particular period could have a materially adverse effect on our business, financial condition and results of operations.

Other Test Systems		79.5		80.5	(1.2	)
	$	1,414.9	$	995.3	42.1	%

Semiconductor Test Systems revenue made up 66.0% of total revenue for the first nine months of 2004, up from 53.3% a year ago. The growth in sales came from both new and existing products, in particular sales of our Catalyst and Flex systems, and was spread over all regions, led by Singapore and Taiwan. The growth was led by the wireless market, but was also driven by growth in the broadband and mass storage/datacom markets as well.

The growth in Connection Systems sales was led by stronger customer demand in the wireless market when comparing the nine months ended October 3, 2004 to the same period in 2003. This growth was also partially offset by a decline in sales due to the decision to exit the lower margin portion of Connection Systems’ EMS business.

The decline in Assembly Test Systems sales was due primarily to a decrease in revenue in the commercial business from the sale of the manual X-ray, rework and AOI product lines offset by a small increase of in-circuit test sales. The decline in the sales of the commercial business were offset by a moderate increase in mil/aero sales.

Gross Margin

Our gross profit was as follows (dollars in millions):

	For the Nine Months Ended						Period Change
	October 3, 2004			September 28, 2003
Gross Profit	$	591.1		$	271.3		$	319.8
Percent of Total Revenue		41.7	%		27.3	%

The gross margin improvement from the first nine months of 2003 to the first nine months of 2004 was a result of several factors. An improvement of 12 points of gross margin is credited to an increase in sales volume and a shift in our mix of revenues, with higher Semiconductor Test Systems content coupled with a shift of Connection Systems business to higher connector content. The remainder is attributable to lower material costs and a reduction in fixed manufacturing costs, including depreciation and facility costs resulting from past restructuring actions.

We assess the carrying value of our inventory on a quarterly basis by estimating future demand and comparing that demand against on-hand and on-order inventory provisions. Forecasted revenue information is obtained from the sales and marketing groups and incorporates factors such as backlog and future revenue demand. This quarterly process identifies obsolete and excess inventory. Obsolete inventory, which represents items for which there is no demand, is fully reserved. Excess inventory, which represents inventory items that are not expected to be consumed during the next four quarters, is written down to estimated net realizable value.

The provisions for excess and obsolete inventory were $9.0 million and $9.1 million for the nine months ended October 3, 2004 and September 28, 2003, respectively. During the nine months ended October 3, 2004, we scrapped $21.2 million of inventory and sold $1.7 million of previously written-down or written-off inventory. As of October 3, 2004, we have inventory related reserves for amounts which had been written-down or written-off of $168.7 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows (dollars in millions):

	For the Nine Months Ended						Period Change
	October 3, 2004			September 28, 2003
Engineering and Development	$	198.9		$	193.6		$	5.3
Percent of Total Revenue		14.1	%		19.5	%

29

The increase of $5 million in engineering and development expenses can be attributed primarily to the following:

• $7 million increase due to variable employee compensation;

• $6 million increase in prototype material for engineering development projects; and

• $4 million increase in outsourced contract engineering.

These increases were offset in part by the following:

• $7 million decrease in the salaries and fringe benefits due to a decrease in headcount, offset by salary increases effective July 1, 2004; and

• $5 million decrease in depreciation as a result of facility closures and lower capital spending including a decrease of $2 million in accelerated depreciation related to asset write-downs and facility closures in the first nine months of 2003.

Selling and Administrative

Selling and administrative expenses were as follows (dollars in millions):

	For the Nine Months Ended						Period Change
	October 3, 2004			September 28, 2003
Selling and Administrative	$	206.5		$	189.0		$	17.5
Percent of Total Revenue		14.6	%		19.0	%

The increase of $18 million in selling and administrative spending is due primarily to the following:

• $16 million increase due to variable employee compensation;

• $5 million from an increase in consulting expenses; and

• $2 million increase in travel and training costs;

These increases were offset in part by the following:

• $4 million in lower depreciation costs due to asset write-downs and capital spending cutbacks; and

• $1 million net decrease in the salaries and fringe benefits due to a decrease in headcount offset by salary increases effective July 1, 2004.

Restructuring and Other Charges

During the nine months ended October 3, 2004, Teradyne recorded the following activity related to restructuring and other charges:

• $1.4 million reversal of revised estimates related to long-lived asset impairment charges that had previously been recorded, and $1.4 million of charges for certain long-lived assets that were impaired as the estimated value of such assets was less than the carrying amount.

• $1.9 million reversal of estimates on future benefits for severed employees. This revision is offset by charges taken for severance and related benefits of $1.2 million. There were approximately 48 employees terminated in the nine months ended October 3, 2004 across Teradyne.

• $2.1 million charge, consisting of $1.2 million of revised estimates of losses due to changes in the assumed amount and timing of sublease income on facilities that have been exited prior to the end of the lease term, and $0.9 million in the Connection Systems segment for a settlement of the remaining lease obligation on a facility.

• $1.2 million net reversal of other charges consisting of $1.0 million of amounts earned under agreements related to product lines that were sold, and $0.2 million of revisions of estimates of liabilities incurred during restructuring activities, both of which occurred in prior reporting periods in the Assembly Test and Other Test Systems segments.

• $0.9 million, as a gain on the sale of a business. This amount related to an earn-out provision from a divestiture in the Connection Systems segment in 1999, and has been classified as gain on the sale of business in the statement of operations for the nine months ended October 3, 2004.

The table below summarizes the liability and activity for the nine months ended September 28, 2003, relating to restructuring and other charges (in thousands):

	Long-Lived Asset Impairment			Severance and Benefits			Loss on Sale of Product Lines			Facility Related			Other Charges		Total
Balance at December 31, 2002	$	—		$	8,242		$	—		$	25,240		$	—	$	33,482

Balance at September 28, 2003	$	—		$	12,441		$	—		$	22,011		$	1,795	$	36,247

During the nine months ended September 28, 2003, Teradyne recorded the following activity related to restructuring and other charges:

• $25.4 million charge primarily for certain long-lived assets held for sale that were impaired as the estimated fair value was less than the carrying value of the assets, including $11.2 million for the sale and leaseback of certain manufacturing assets, and $8.2 million for a reduction in the fair value of properties held for sale in the Connection Systems segment. The charge for the Semiconductor Test Systems segment of $5.5 million related primarily to a reduction in the fair value of properties held for sale, and $0.5 million related to the impairment of manufacturing assets held for sale in the Assembly Test Systems segment.

• $19.7 million charge for severance and related benefits. There were approximately 800 employees terminated in the first nine months of 2003 across Teradyne.

• $8.1 million charge for the loss on sale of product lines, of which $6.9 million has been recorded in restructuring and other charges and $1.2 million in each period has been recorded in cost of sales. The product lines sold were in the Assembly Test and Other Test Systems segments. In the first quarter of 2003, the Assembly Test Systems segment sold its manufacturing software product line and manual x-ray inspection and rework product line for total cash proceeds of $2.1 million. These transactions

31

resulted in a loss of $6.7 million for the nine months ended September 28, 2003 of which $6.2 million has been recorded in restructuring and other charges, and $0.5 million has been recorded in cost of sales. In the nine months ended September 28, 2003, the Other Test Systems segment recorded a charge of $1.4 million to write down its net assets relating to the sale of the Autodiagnosis automotive after market product line of which $0.7 million has been recorded in restructuring and other charges and $0.7 million has been recorded in cost of sales.

• $2.4 million charge, consisting primarily of revised estimates of losses due to changes in the assumed amount and timing of sublease income on facilities that have been exited prior to the end of the lease term. The Connection Systems segment recorded $1.4 million of this charge and $1.0 million was recorded in the Assembly Test Systems segment.

• $1.8 million charge primarily for contractual penalties associated with resizing the Connections Systems segment.

Interest Income and Expense

Interest income decreased to $10.8 million for the first nine months of 2004 from $11.0 million in the first nine months of 2003, due primarily to a reduction in interest rates. Interest expense decreased to $14.2 million in the first nine months of 2004 from $16.3 million in the first nine months of 2003 as a result of the prepayment of our mortgage for our California properties in the third quarter of 2003.

Other Income and Expense, Net

Other income and expense, net for the nine months ended October 3, 2004 and September 28, 2003, respectively, includes the following (in thousands):

	For the nine months ended
	October 3, 2004			September 28, 2003
Mortgage prepayment penalty (1)	$	—		$	(3,220	)
Other than temporary impairment of investment		—			(2,592	)
Repayment of loan (2)		585			—
Gain on sale of an investment		1,058			1,250
Fair value adjustment on warrants		(366	)		31
Total	$	1,277		$	(4,531	)

(1) Penalties related to the prepayment of a $45 million mortgage loan collateralized against certain California real estate properties, which was to mature January 1, 2007.

(2) The loan had previously been valued at zero due to its uncertainty of collection.

Income Taxes

As a result of incurring significant operating losses from 2001 through 2003, we determined that it was more likely than not that our deferred tax assets may not be realized, and since the fourth quarter of 2002 we established a full valuation allowance for our net deferred tax assets. If we generate sustained future taxable income against which these tax attributes may be applied, some portion or all of the valuation allowance would be reversed. If the valuation allowance were reversed, a portion would be recorded as an increase to additional paid in capital, and the remainder would be recorded as a reduction to income tax expense. Similar to prior periods, the tax expense in the first nine months of 2004 is composed of amounts recorded for foreign taxes, however, it also includes an IRS settlement of $3.0 million related to the closing out of tax years 1999 through 2001, and an adjustment to our estimated annual tax rate from 10% to 10.5%. The tax expense for 2003 relates primarily to a tax provision for foreign taxes, and was recorded using an estimated annual effective tax rate of 3%.

32

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balance increased $89.6 million in the first nine months of 2004, to $675.6 million. Cash activity for the first nine months of 2004 and 2003 was as follows (in millions):

	For the Nine Months Ended
	October 3, 2004			September 28, 2003
Cash provided by (used for) operating activities:	$	197.2		$	(1.0	)
Cash provided by (used for) net income (loss), adjusted for non-cash items	$	265.2		$	(16.9	)
Changes in operating assets and liabilities, net of product lines sold		(68.0	)		15.9
Total cash provided by (used for) operating activities	$	197.2		$	(1.0	)
Cash used for investing activities		(182.0	)		(108.2	)
Cash provided by financing activities		20.4			44.7
Increase (decrease) in cash	$	35.6		$	(64.5	)

Changes in operating assets and liabilities, net of product lines sold used cash of $68.0 million in the first nine months of 2004 due to increased accounts receivable and inventory balances, offset by an increase in accounts payable, deferred revenue and accrued expenses. Accounts receivable balances increased $26.0 million, primarily in the Semiconductor Test segment, due to an increase in sales offset by a decrease in days sales outstanding (“DSO”) from 63 days as of September 28, 2003 to 51 days as of October 3, 2004. The decrease in DSO year over year is mainly related to increased collection efforts and the timing of sales during the nine-month period. Inventory increased $55.3 million in the first nine months of 2004 due primarily to volume increases in our Semiconductor Test Systems segment. Accounts payable, deferred revenue and accrued expenses had a net decrease of $3.2 million. We plan to contribute $10 million to the U.S. Qualified Pension Plan in the fourth quarter of 2004, and approximately $30 million during 2005. Changes in operating assets and liabilities, net of product lines sold provided cash of $15.9 million in the first nine months of 2003, primarily due to an increase in accounts receivable balances offset by a decrease in inventory and an increase in accounts payable, deferred revenue and accrued expenses.

Investing activities consist of cash paid for assets and purchases of capital assets, as well as the purchase, sale and maturity of marketable securities, and proceeds from asset disposals and the sale of product lines. Capital expenditures, including internally manufactured test equipment, increased by $68.8 million in the first nine months of 2004 compared to the first nine months of 2003 across all operating segments, primarily related to increased spending on internally constructed test systems and purchases of computer equipment. Lastly, during the nine months ended October 3, 2004, Teradyne received $1.5 million in proceeds for amounts earned under agreements related to product lines sold in prior reporting periods.

Financing activities represent the sale of our common stock and payments on long-term debt and our convertible senior notes. The decrease of $24.3 million from the first nine months of 2003 to the first nine months of 2004 is due primarily to a decrease in stock option exercises and the repurchase of $8.5 million of our convertible senior notes in the three months ended October 3, 2004. The decision to repurchase a portion of our notes was based on the fair market value of the notes being below face value during the period.

We believe our cash, cash equivalents and marketable securities balance of $675.6 million will be sufficient to meet working capital and expenditure needs for at least the next twelve months. Inflation has not had a significant long-term impact on earnings.

Employee Stock Options

Our equity compensation program is a broad-based, long-term retention program that is intended to attract and retain talented employees and align stockholder and employee interests. Of the stock options we granted in 2003, 87% went to employees other than the Chief Executive Officer and the five other most highly compensated executive officers.

Equity Compensation Plans

In addition to our 1996 Employee Stock Purchase Plan discussed in Note B: “Accounting Policies,” in our Annual Report on Form 10-K for the year ended December 31, 2003, we maintain three equity compensation plans under which equity securities are authorized for issuance to our employees, directors and/or consultants:

1) 1991 Employee Stock Option Plan;

2) 1997 Employee Stock Option Plan; and

3) 1996 Non-Employee Director Stock Option Plan.

35

The purpose of these plans is to promote our interests by attracting and retaining the services of qualified and talented persons to serve as employees, directors and/or consultants. Except for the 1997 Employee Stock Option Plan, each of the foregoing plans was approved by our shareholders.

The following table presents information about these plans as of October 3, 2004 (shares in thousands):

Upon the consummation of the Acquisition, these options became exercisable for shares of our common stock based on an exchange ratio of 0.1733 shares of Teradyne common stock for each share of GenRad common stock. No additional options will be granted pursuant to the GenRad Plans. As of October 3, 2004, there were outstanding options exercisable for an aggregate of 264 shares of our common stock pursuant to the GenRad Plans, with a weighted average exercise price of $70.67 per share.

Risk Factors

Certain Factors That May Affect Future Results

From time to time, information we provide, statements made by our employees or information included in our filings with the Securities and Exchange Commission (including this Form 10-Q) contain statements that are not purely historical, but are forward looking statements, made under Section 21E of the Securities Exchange Act of 1934, which involve risks and uncertainties. In particular, forward looking statements made herein include projections, plans and objectives for our business, financial condition, operating results, future operations, or future economic performance, statements relating to the sufficiency of capital to meet working capital requirements, capital expenditures, expectations as to customer orders and demand for our products and statements relating to backlog, bookings and cancellations, gross margins and pricing considerations. These statements are neither promises nor guarantees but involve risks and uncertainties, both known and unknown, which could cause our actual future results to differ materially from those stated in any forward looking statements. Factors that may cause such differences include, but are not limited to, the factors discussed below. These factors, and others, are discussed from time to time in our filings with the Securities and Exchange Commission, including in our Annual Report on Form 10-K for the year ended December 31, 2003.

Our Business Is Impacted by Worldwide Economic Cycles.

Capital equipment providers in the electronics and semiconductor industries, such as Teradyne, were negatively impacted by the slowdown in the global economies, and resulting reductions in customer capital

36

investments, that began in the second half of 2000. Future slowdowns in global economies and reductions in customer capital investments, which may adversely impact our business, are difficult to predict.

Acts of War, Terrorists Attacks and the Threat of Domestic and International Terrorist Attacks May Adversely Impact Our Business.

Acts of war and terrorists attacks may cause damage or disruption to our employees, facilities, customers, suppliers and distributors which could have a material adverse effect on our business, results of operation or financial condition. As we sell and manufacture products both in the United States and internationally, the threat of future terrorist attacks could lead to changes in security and operations at those locations which could increase our operating costs and which may adversely affect our business. Such conflicts may also cause damage or disruption to transportation and communication systems. All of these conditions make it difficult for us, and our customers, to accurately forecast and plan future business activities and could have a material adverse effect on our business, financial condition and results of operations.

Our Business is Dependent on the Current and Anticipated Market for Electronics.

Our business and results of operations depend in significant part upon capital expenditures of manufacturers of semiconductors and other electronics, which in turn depend upon the current and anticipated market demand for those products. The market demand for electronics was impacted by the economic slowdown that began in the latter portions of 2000 and the effects of the hostilities which began in September 2001. Historically, the electronics and semiconductor industry has been highly cyclical with recurring periods of over-supply, which often have had a severe negative effect on demand for test equipment, including systems we manufacture and market. We believe that the markets for newer generations of electronic products such as those that we manufacture and market will also be subject to similar fluctuations. We are dependent on the timing of orders from our customers and the deferral or cancellation of previous customer orders could have an adverse effect on our results of operations. We cannot assure that the level of revenues or new orders for a calendar quarter will be sustained in subsequent quarters. In addition, any factor adversely affecting the electronics industry or particular segments within the electronics industry may adversely affect our business, financial condition and operating results.

We Have Taken Measures to Address the Slowdown in the Market for Our Products Which Could Have Long-term Negative Effects on Our Business.

During 2001, 2002, 2003, and 2004, we took measures to address slowdowns in the market for our products. In particular, we reduced our workforce, closed and/or sold facilities, discontinued certain product lines, implemented material cost reduction programs and reduced planned capital expenditures and expense budgets. Each measure we took to address such slowdowns could have long-term negative effects on our business by reducing our pool of technical talent, decreasing or slowing improvements in our products, increasing our debt, and making it more difficult to respond to customers or competitors, as the market and customer orders turn around.

We May Not Be Able to Adequately Address a Rapid Increase in Customer Demand.

Because we took measures during the past four years to scale back operations and reduce expenses in response to decreased customer demand for products and services, we may not be able to satisfy a rapid increase in customer demand. Our ability to meet rapid increases in customer demand is also, to a certain extent, dependant upon the ability of our suppliers and contractors to meet increased product or delivery requirements, over which we have little or no control.

37

Our Business May Be Adversely Impacted by Acquisitions Which May Affect Our Ability to Manage and Maintain Our Business.

Since our inception, we have acquired a number of businesses. In the future, we may undertake additional acquisitions of businesses that complement our existing operations. Such past or future acquisitions could involve a number of risks, including:

• the diversion of the attention of management and other key personnel;

• the costs associated with and/or the inability to effectively integrate an acquired business into our culture, product and service delivery methodology and other standards, controls, procedures and policies;

• the inability to retain the management, key personnel and other employees of an acquired business;

• the inability to retain the customers of an acquired business;

• the possibility that our reputation will be adversely affected by customer satisfaction problems of an acquired business;

• potential known or unknown liabilities associated with an acquired business, including but not limited to regulatory, environmental and tax liabilities;

• significant underperformance of the acquired business relative to our expectations;

• the amortization of acquired identifiable intangibles, which may adversely affect our reported results of operations; and

• litigation which has or which may arise in the future in connection with such acquisitions.

For example, in connection with the August 2000 acquisition of each of Herco Technology Corp., a California company, and Perception Laminates, Inc., a California company, a complaint was filed on or about September 5, 2001 and is now pending in Federal District Court, San Diego, California, by the former owners of those companies naming as defendants Teradyne and two of our executive officers. This case is further described in “Item 1: Legal Proceedings” in this Form 10-Q.

Additionally, in 2001, we were designated as a “potentially responsible party” (“PRP”) at a clean-up site in Los Angeles, California. This claim arises out of our acquisition of Perception Laminates, Inc. in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an asset purchase agreement dated July 30, 1992. This case is further described in “Item 1: Legal Proceedings” in this Form 10-Q.

We Currently Are and in the Future May Be Subject to Litigation that Could Have an Adverse Effect on Our Business.

From time to time, we may be subject to litigation or other administrative and governmental proceedings that could require significant management time and resources and cause us to incur expenses and, in the event of an adverse decision, pay damages in an amount that could have a material adverse effect on our financial position or results of operations.

For example, on April 30, 2004, Hampshire Equity Partners II, L.P. (“HEP”), filed a complaint against Teradyne and Teradyne Connection Systems segment (“TCS”) asserting fraud and negligence based claims, and a claim for intentional interference with economic opportunity. In the complaint, HEP alleges that it relied upon statements made by a representative of TCS to a HEP agent during its due diligence prior to investing $55 million in Connector Services Corporation, aka AMAX Plating, Inc (“CSC”). HEP seeks to hold Teradyne and TCS responsible for its decision to invest in CSC and for the losses it has suffered upon the bankruptcy of CSC. HEP seeks damages in an unstated amount exceeding $55 million. The case is currently pending in the

38

U.S. District Court of the Southern District of New York. We believe we have meritorious defenses to the claims and will defend ourselves vigorously. Management does not believe that the outcomes of these claims will have a material adverse effect on our financial position or results of operations but there can be no assurance that any such claims would not have a material adverse effect on our financial position or results of operations. This case is further described in “Item 1: Legal Proceedings” in this Form 10-Q.

We Currently Face, and in the Future May Be the Subject of, Securities Class Action Litigation Due to Past or Future Stock Price Volatility.

Teradyne and two of our executive officers were named as defendants in three purported class action complaints that were filed in Federal District Court, Boston, Massachusetts, in October and November 2001. The court consolidated the cases and has appointed three lead plaintiffs. On November 8, 2002, plaintiffs filed and served a consolidated amended class action complaint. The complaint alleges, among other things, that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by making, during the period from July 14, 2000 until October 17, 2000, material misrepresentations and omissions to the investing public regarding our business operations and future prospects. The complaint seeks unspecified damages, including compensatory damages and recovery of reasonable attorneys’ fees and costs. A motion was filed to dismiss all claims asserted in the complaint on February 7, 2003. On January 16, 2004, the U.S. Magistrate Judge recommended to the U.S. District Court that our motion to dismiss the consolidated amended class action complaint in its entirety be allowed without prejudice. On February 2, 2004, the lead plaintiffs filed an objection to the U.S. Magistrate Judge’s recommendation. On March 2, 2004, we filed our response to the lead plaintiffs objection. On September 8, 2004, the U.S. District Court adopted the U.S. Magistrate Judge’s recommendation and dismissed the consolidated amended class action complaint in its entirety without prejudice. Management does not believe that the outcomes of these claims will have a material adverse effect on our financial position or results of operations but there can be no assurance that any such claims would not have a material adverse effect on our financial position or results of operations. These cases are further described in “Item 1: Legal Proceedings” in this Form 10-Q.

Our Business May be Adversely Impacted by Divestitures of Lines of Business Which May Affect Our Ability to Manage and Maintain Our Business.

Since our inception, we have divested certain lines of business. In the future, we may undertake additional such divestitures. Such past or future divestitures could involve a number of risks, including:

• the diversion of the attention of management and other key personnel;

• disruptions and other effects caused by the divestiture of a line of business on our culture, product and service delivery methodology and other standards, controls, procedures and policies;

• customer satisfaction problems caused by the loss of a divested line of business;

• restructuring, inventory and other charges which may affect our results of operations; and

• the decreased diversification of our product lines caused by the divestiture of a line of business which may make our operating results subject to increased market fluctuations.

If We Are Unable to Protect Our Intellectual Property, We May Lose a Valuable Asset or May Incur Costly Litigation to Protect Our Rights.

Our products incorporate technology that we protect in several ways, including patents, copyrights, trade secrets and by contract (“IP”). However, even with these protections, our IP may still be challenged, invalidated or subject to other infringement actions. While we believe that our IP has value in the aggregate, no single element of our IP is in itself essential. If a significant portion of our IP is invalidated or ineffective, our business could be materially adversely affected. In addition, we receive notifications from time to time that we may be in

39

violation of patents held by others. An assertion of patent infringement against us, if successful, could have a material adverse effect on our ability to sell our products, or require a significant use of management resources and necessitate a lengthy and expensive defense which could adversely affect our operating results.

If We Fail to Develop New Technologies to Adapt to Our Customers’ Needs and if Our Customers Fail to Accept Our New Products, Our Revenues Will Be Adversely Affected.

We believe that our technological position depends primarily on the technical competence and creative ability of our engineers. In a rapidly evolving market, such as ours, the development of new technologies, commercialization of those technologies into products and market acceptance and customer demand for those products are critical to our success. Successful product development and introduction depends upon a number of factors, including:

• new product selection;

• ability to meet customer requirements;

• development of competitive products by competitors;

• timely and efficient completion of product design;

• timely and efficient implementation of manufacturing; and

• assembly processes and product performance at customer locations.

We Are Subject to Intense Competition.

We face significant competition throughout the world in each of our operating segments. Some of our competitors have substantial financial and other resources to pursue engineering, manufacturing, marketing and distribution of their products. We also face competition from internal suppliers at several of our customers. Some of our competitors have introduced or announced new products with certain performance characteristics which may be considered equal or superior to those we currently offer. We expect our competitors to continue to improve the performance of their current products and to introduce new products or new technologies that provide improved cost of ownership and performance characteristics. New product introductions by competitors could cause a decline in revenues or loss of market acceptance of our products. Moreover, increased competitive pressure could lead to intensified price based competition, which could materially adversely affect our business, financial condition and results of operations.

We Are Subject to Risks of Operating Internationally.

A significant portion of our total revenue is derived from customers outside the United States. Our international sales and operations are subject to significant risks and difficulties, including:

• unexpected changes in legal and regulatory requirements and in policy changes affecting international markets;

• changes in tariffs and exchange rates;

• social, political and economic instability, acts of terrorism and international conflicts;

• difficulties in accounts receivable collection;

• cultural differences in the conduct of business;

• difficulties in staffing and managing international operations;

• potentially adverse tax consequences; and

• compliance with customs regulations.

40

In addition, an increasing portion of our products are sourced or manufactured in foreign locations, including China, and a large portion of the devices our products test are fabricated and tested by foundries and subcontractors in Taiwan, Singapore, China and other parts of Asia. As a result, we are subject to a number of economic and other risks, particularly during times of political or financial instability in these regions. Disruption of manufacturing or supply sources in these international locations could materially adversely impact our ability to fill customer orders and potentially result in lost business.

Our Business May Suffer if We Are Unable to Attract and Retain Key Employees.

Competition for employees with skills we require is intense in the high technology industry. Our success will depend on our ability to attract and retain key technical employees. The loss of one or more key or other employees, our inability to attract additional qualified employees, or the delay in hiring key personnel could each have a material adverse effect on our business, results of operations or financial condition.

If Our Suppliers do not Meet Product or Delivery Requirements, We Could Have Reduced Revenues and Earnings.

Certain components, including semiconductor chips, may be in short supply from time to time because of high industry demand or the inability of some vendors to consistently meet our quality or delivery requirements. Approximately 30% of material purchases require some custom work where having multiple suppliers would be cost prohibitive. If any of our suppliers were to cancel contracts or commitments or fail to meet the quality or delivery requirements needed to satisfy customer orders for our products, we could lose time-sensitive customer orders and have significantly decreased quarterly revenues and earnings, which would have a material adverse effect on our business, results of operations and financial condition. In addition, we rely on contract manufacturers for certain subsystems used in our products, and our ability to meet customer orders for those products depends upon the timeliness and quality of the work performed by these subcontractors, over whom we do not exercise any control.

We are also dependent on the financial strength of our suppliers and may be subject to litigation arising from our relationships with suppliers and others. There can be no assurance that the loss of suppliers either as a result of bankruptcy or otherwise will not have a material adverse effect on our business, results of operations or financial condition.

We May Incur Significant Liabilities if We Fail to Comply With Environmental Regulations.

We are subject to both domestic and international environmental regulations and statutory strict liability relating to the use, storage, discharge, site cleanup and disposal of hazardous chemicals used in our manufacturing processes. If we fail to comply with present and future regulations, or are required to perform site remediation, we could be subject to future liabilities or the suspension of production. Present and future regulations may also:

• restrict our ability to expand facilities;

• require us to acquire costly equipment; or

• require us to incur other significant costs and expenses.

Pursuant to present regulations and agreements, we are conducting groundwater and subsurface assessment and monitoring and are implementing remediation and corrective action plans for facilities located in California, Massachusetts and New Hampshire which are no longer conducting manufacturing operations. As of November 4, 2004, we have not incurred material costs as result of the monitoring and remediation steps taken at the California, Massachusetts and New Hampshire sites.

41

On January 27, 2003, the European Union adopted the following directives: (i) the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (the “RoHS Directive”); and (ii) the Waste Electrical and Electronic Equipment Directive (the “WEEE Directive”). Both the RoHs Directive and the WEEE Directive will alter the type and manner in which electronic equipment is imported, sold and handled in the European Union. Ensuring compliance with the RoHs Directive and the WEEE Directive could result in additional costs and disruption to operations and logistics and thus, could have a negative impact on the business, operations and financial condition. The RoHs Directive and the WEEE Directive will be become effective on July 6, 2006 and August 13, 2005, respectively.

We Have Substantially Increased Our Indebtedness.

On October 24, 2001, we completed a private placement of $400 million principal amount of 3.75% Convertible Senior Notes (the “Notes”) due October 15, 2006 and received net proceeds of $389 million. As a result, we have incurred approximately $400 million principal amount of additional indebtedness, substantially increasing our ratio of debt to total capitalization. The level of our indebtedness, among other things, could:

• make it difficult to make payments on our debt and other obligations;

• make it difficult to obtain any necessary future financing for working capital, capital expenditures, debt service requirements or other purposes;

• require the dedication of a substantial portion of any cash flow from operations to service for indebtedness, thereby reducing the amount of cash flow available for other purposes, including capital expenditures;

• limit our flexibility in planning for, or reacting to changes in our business and the industries in which we compete;

• place us at a possible competitive disadvantage with respect to less leveraged competitors and competitors that have better access to capital resources; and

• make us more vulnerable in the event of a downturn in our business.

During the quarter ending October 3, 2004, Teradyne has taken steps to reduce its indebtedness, including repurchasing $8.5 million of the Notes on the open market. There can be no assurance that we will be able to meet our debt service obligations, including our obligations under the Notes.

We May Not Be Able to Satisfy Certain Obligations in the Event of a Change in Control.

The indenture governing the Notes contains provisions that apply to a change in control of Teradyne. If a “change in control” occurs, the holders of the Notes have the right to require us to repurchase all of the Notes not previously called for redemption. The price that we are required to pay is 100% of the principal amount of the Notes to be repurchased, together with interest accrued but unpaid to, but excluding, the repurchase date. At our option and subject to the satisfaction of certain conditions, instead of paying the repurchase price in cash, we may pay the repurchase price in common stock valued at 95% of the average of the closing prices of common stock for the five trading days immediately preceding and including the third trading day prior to the repurchase date. If we are required to repurchase the Notes, there is no guarantee that we will have enough funds to pay such amounts.

As a result, a change in control could have a material adverse effect on our business, results of operations or financial condition.

We May Not Be Able to Pay Our Debt and Other Obligations.

If our cash flow is inadequate to meet our obligations, we could face substantial liquidity problems. If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments on the

42

Notes or certain of our other obligations, we would be in default under the terms thereof, which would permit the holders of those obligations to accelerate their maturity and also could cause defaults under future indebtedness we may incur. Any such default could have a material adverse effect on our business, prospects, financial position and operating results. In addition, we cannot assure that we would be able to repay amounts due in respect of the Notes if those obligations were to be accelerated following the occurrence of any other event of default as defined in the instruments creating those obligations. Moreover, we cannot assure that we will have sufficient funds or will be able to arrange for financing to pay the principal amount due on the Notes at maturity.

We May Need Additional Financing, Which Could Be Difficult to Obtain.

We expect that our existing cash and marketable securities and cash generated from operations will be sufficient to meet our cash requirements to fund operations and expected capital expenditures for the next twelve months. However, we have a finite amount of cash and in the event we may need to raise additional funds, due to losses or other reasons, we cannot be certain that we will be able to obtain such additional financing on favorable terms, if at all. Further, if we issue additional equity securities, stockholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of existing holders of common stock. Future financings may place restrictions on how we operate our business. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products and services, take advantage of future opportunities, grow our business or respond to competitive pressures, which could seriously harm our business.

If We Are Required to Account for Options Under Our Employee Stock Plans as a Compensation Expense, Our Reported Operating Results Will Be Adversely Affected.

There has been an increasing public debate about the proper accounting treatment for employee stock options. We currently disclose pro forma compensation expense quarterly and annually by calculating the grants’ fair value and disclosing the impact on net income (loss) and net income (loss) per share in a footnote to the consolidated financial statements. If future laws and regulations require us to record the fair value of all stock options as compensation expense in our consolidated statement of operations, our reported operating results will be adversely affected. Note B: “Accounting Policies,” of the consolidated financial statements reflects the impact that such a change in accounting treatment would have had on net income (loss) and net income (loss) per share if it had been in effect during the three months ended October 3, 2004 and September 28, 2003. Included in Item 2: “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are additional stock-based compensation disclosures.

Provisions of Our Charter and By-Laws and Massachusetts Law Make a Takeover of Teradyne More Difficult.

Our basic corporate documents, our stockholder rights plan and Massachusetts law contain provisions that could discourage, delay or prevent a change in control, even if a change in control might be regarded as beneficial to some or all of our stockholders.

Our Operating Results Are Likely to Fluctuate Significantly.

Our annual operating results are affected by a wide variety of factors that could materially adversely affect revenues and profitability.

The following factors set out below are expected to impact future operations:

• competitive pressures on selling prices;

• our ability to introduce and the market acceptance of new products planned for 2004 and beyond;

• changes in product revenue mix resulting from changes in customer demand;

43

• the level of orders received which can be shipped in a quarter resulting from the tendency of customers to wait until late in a quarter to commit to purchase due to capital expenditure approvals and constraints occurring at the end of a quarter, or the hope of obtaining more favorable pricing from a competitor seeking the business;

• engineering and development investments relating to new product introductions in 2004 and beyond, and the expansion of manufacturing and engineering operations in Asia;

• the ability of our suppliers and subcontractors to meet product quality or delivery requirements needed to satisfy customer orders for our products, especially if product demand increases rapidly;

• provisions for excess and obsolete inventory relating to the lack of demand for and the discontinuance of products; and

• impairment charges for certain long-lived assets.

In particular, due to the introduction of a number of new, complex test systems in 2003 and the planned introduction of other systems in 2004 and beyond, there can be no assurance that we will not experience delays in shipment of our products or that our products will achieve customer acceptance.

As a result of the foregoing and other factors, we have and may continue to experience material fluctuations in future operating results on a quarterly or annual basis which could materially and adversely affect our business, financial condition, operating results and stock price.

We have Significant Guarantees and Indemnification Obligations

From time to time we make guarantees to customers regarding the performance of our products, guarantee certain indebtedness obligations of our subsidiary companies and have agreed to provide indemnification to our officers, directors, employees and agents, to the extent permitted by law, arising from certain events or occurrences while the officer, director, employee or agent, is or was serving at our request in such capacity. If we become liable under any of these obligations, it could materially and adversely affect our business, financial condition and operating results. For additional information regarding “Guarantees and Indemnification Obligations” see Note J: “Commitments and Contingencies” in our Annual Report on Form 10-K for the year ended December 31, 2003. In addition to the guarantee and indemnification obligations set forth in our Annual Report, Teradyne occasionally guarantees the performance obligations and responsibilities of its subsidiary and affiliate companies.

Item 3: Quantitative and Qualitative Disclosures about Market Risk

For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Item 7a. “Quantitative and Qualitative Disclosures About Market Risks,” in our Annual Report on Form 10-K filed with the SEC on March 15, 2004. There were no material changes in our exposure to market risk from those set forth in our Annual Report for the fiscal year ended December 31, 2003.

Item 4: Controls and Procedures.

As of the end of the period covered by this report, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that material information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the

44

Securities and Exchange Commission’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

During the period covered by this report, there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. The design of a control system is based in part upon certain assumptions of the likelihood of certain future events, and there can be no assurance that any design will succeed in achieving its goals under all possible future conditions. Because of inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

Item 1: Legal Proceedings

After the August 2000 acquisition of Herco Technology Corp. and Perception Laminates, Inc. the former owners of those companies filed a complaint on September 5, 2001 against Teradyne and two of our executive officers. The case is now pending in Federal District Court, in San Diego, California. We filed a motion to dismiss the complaint in its entirety on behalf of Teradyne and the two individual defendants. The court granted the motion in part, and the only remaining claims were that the sale of our common stock to the former owners violated certain California securities statutes and common law and that we had breached certain contractual obligations in the agreements relating to the acquisitions. Our subsequent motion for partial summary judgment with respect to the breach of contract claims was granted on November 7, 2002. On December 9, 2002, the plaintiffs filed a motion asking the court to reconsider its summary judgment ruling or, alternatively, for certification under Rule 54(b) which would grant the plaintiffs leave to appeal both the Court’s ruling regarding dismissal of claims and its ruling granting summary judgment to the Ninth Circuit Court of Appeals. We opposed these motions. On April 22, 2003, the Court denied the plaintiffs’ motion from reconsideration and the plaintiffs’ request for certification under Rule 54(b). The only claim still pending before the District Court from the original complaint relates to an allegation of fraud in connection with the setting of the transaction price. We have answered and denied all liability.

Teradyne and two of our executive officers were named as defendants in three purported class action complaints that were filed in Federal District Court, Boston, Massachusetts, in October and November 2001. The court consolidated the cases and has appointed three lead plaintiffs. On November 8, 2002, plaintiffs filed and served a consolidated amended class action complaint. The complaint alleges, among other things, that the defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by making, during the period from July 14, 2000 until October 17, 2000, material misrepresentations and omissions to the investing public regarding our business operations and future prospects. The complaint seeks unspecified damages, including compensatory damages and recovery of reasonable attorneys’ fees and costs. We filed a motion to dismiss all claims asserted in the complaint on February 7, 2003. On January 16, 2004, the U.S. Magistrate Judge recommended to the U.S. District Court that our motion to dismiss the consolidated amended class action complaint in its entirety be allowed without prejudice. On February 2, 2004, the lead plaintiffs filed an objection to the U.S. Magistrate Judge’s recommendation. We filed our response to the lead plaintiff’s objection. On September 8, 2004, the U.S. District Court adopted the U.S. Magistrate Judge’s recommendation and dismissed the consolidated amended class action complaint in its entirety without prejudice.

In 2001, we were designated as a “potentially responsible party” (“PRP”) at a clean-up site in Los Angeles, California. This claim arises out of our acquisition of Perception Laminates, Inc. in August 2000. Prior to that date, Perception Laminates had itself acquired certain assets of Alco Industries Inc. under an asset purchase agreement dated July 30, 1992. Neither Teradyne nor Perception Laminates have ever conducted any operations at the Los Angeles site. We have asked the State of California to drop the PRP designation, but California has not yet agreed to do so.

On April 30, 2004, Hampshire Equity Partners II, LP (“HEP”) filed a complaint against Teradyne and Teradyne’s Connection Systems segment (“TCS”) in the United States District Court of the Southern District of New York, relating to its February 21, 2001 investment of $55 million in Connector Service Corporation aka AMAX Plating, Inc. (“CSC”), which was a supplier to TCS at the time. During the due diligence that HEP conducted prior to making that investment, an agent of HEP spoke with TCS, among other CSC customers, concerning CSC. On or about September 24, 2003, CSC filed for bankruptcy protection as discussed above. HEP has now brought suit against Teradyne and TCS asserting fraud and negligence based claims, and a claim for intentional interference with economic opportunity, relating to statements that a TCS representative made to HEP’s agent prior to HEP’s February 2001 investment in CSC. HEP seeks to hold Teradyne and TCS responsible for its decision to invest in CSC and for the losses that it suffered upon the bankruptcy of CSC. HEP is now seeking damages for an unstated amount of not less than $55 million. On June 17, 2004, Teradyne and TCS filed

46

a motion to dismiss HEP’s complaint in its entirety. On August 9, 2004, HEP filed its opposition to the motion to dismiss and Teradyne filed its reply brief on September 22, 2004. Teradyne’s motion to dismiss remains pending.

We believe that we have meritorious defenses against the above unsettled claims and intend to vigorously contest them. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, we believe the losses associated with all of these actions will not have a material adverse effect on our consolidated financial position or liquidity, but could possibly be material to our consolidated results of operations of any one period.

In addition, we are subject to legal proceedings, claims and investigations that arise in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Although there can be no assurance, there are no such matters pending that we expect to be material with respect to our business, financial position or results of operations.

Exhibit 10.45

AGREEMENT REGARDING TERMINATION BENEFITS

This “Agreement Regarding Termination Benefits” (“Agreement”) is entered into as of September 3, 2004 (the “Effective Date”) between Teradyne, Inc., a Massachusetts Corporation with a principal office at 321 Harrison Avenue, Boston, Mass. 02118 (the “Company”) and Michael A. Bradley with a residential address of XXXXXXXXXXXXXXXXX (“Executive”).

(an “Acquiror”) so long as (i) the Executive’s services do not involve products or services that are competitive to those that were produced, marketed, sold or rendered by Teradyne, Inc. or any of its subsidiaries (including actual or demonstratively anticipated research or development) before the acquisition (“Teradyne Product/Services”) and (ii) the Executive is not retained as an Officer of the Acquiror following the consummation of the acquisition to render services involving the Acquiror’s products and services which are not Teradyne Products/Services.

f) Establishing, funding, purchasing or managing a business which is competitive with the business of the Company or its subsidiaries.

3. Employment & Agreement Consideration: In consideration of (a) the Executive’s “at-will” employment with the Company following the Executive’s recent election to the position of Chief Executive Officer of the Company and the compensation payments made to the Executive as a consequence thereof and (b) the Company’s willingness to enter into an agreement regarding termination benefits, specifically this Agreement, the Executive covenants and agrees that during the Term of this Agreement and for two (2) years after the Executive’s Date of Termination resulting from the Executive’s Resignation, Retirement or a termination by the Company for Cause, the Executive will not directly or indirectly engage in any of the Restricted Activities.

4. Termination Benefits and Covenants:

4.1 For the Executive: In consideration of, and as condition to, the Executive providing to the Company the covenants and agreements set forth in Section

3

4.3 below, the Company shall provide the following Termination Benefits to the Executive if his employment with the Company is terminated by the Company for any reason other than for Death, Disability, or Cause, regardless of whether prior to, following or relating to a Change of Control.

(a) Continued Payments: The Company shall pay the Executive a monthly amount equal to 1/12^th of his current annual Model Compensation as of the Date of Termination for a period of twenty-four (24) months from the Date of Termination (the “Severance Period”). Except as otherwise expressly provided herein, under no circumstances shall the Executive receive more than a total of twenty-four (24) months of payments under this Agreement. All such continued payments shall be in accord with the Company’s usual model compensation pay practices.

(b) Benefits: During the Severance Period, the Company shall arrange for continued health, dental and vision insurance plan coverage for the Executive at the same levels of coverage in existence prior to the Date of Termination subject to the Company and Executive each contributing to the applicable insurance premium payments on the same basis and in the same proportions as in existence at the Date of Termination. If the Executive is not eligible for continued health, dental and vision insurance plan coverage for any portion of the Severance Period, the Company shall provide or reimburse the Executive for comparable individual insurance and, if such provision or reimbursement constitutes taxable income to the Executive, such additional amount as is necessary to place the Executive in substantially the same after tax position as he was while an employee of the Company with respect to such insurance plan coverages. All other benefits, including but not limited to flex/vacation time accrual, short and long term disability insurance, and life insurance, contributions (including company matches) into savings plan and savings plan plus, profit sharing payments and participation in the Executive stock purchase plan shall cease as of the Date of Termination.

(c) Stock Options: All stock options held by the Executive shall be governed exclusively by the terms of the applicable Stock Option Plan(s) and Stock Option Agreements (including any successor plans and agreements) under which the stock options were granted to the Executive and the Executive Officer Change in Control Agreement between the Executive and the Company dated October 19, 2001. Except as otherwise expressly stated herein, this Agreement shall not modify or alter any of the terms applicable to the Executive’s stock options, including but not limited to the vesting schedule.

The arbitrator shall be selected in accordance with the Employment Dispute Resolution Rules of the American Arbitration Association (“AAA”) pertaining at the time the dispute arises. The parties agree that such arbitration shall take place at the offices of the AAA in Boston, Massachusetts. In such arbitration proceedings, the arbitrator shall have the discretion, to be exercised in accordance with applicable law, to allocate among the parties the arbitrator’s fees, tribunal and other administrative and litigation costs and, to the prevailing party, reasonable attorneys’ fees. The award of the arbitrator may be confirmed before and entered as a judgment of any court having jurisdiction of the parties.

12. Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts without giving effect to the conflicts of law principles thereof, and this Agreement shall be deemed to be performable in Massachusetts.

14. Waivers and Modifications. This Agreement may be modified, and the rights, remedies and obligations contained in any provision hereof may be waived, only in accordance with this Section 14. No waiver by either party of any breach by the other or any provision hereof shall be deemed to be a waiver of any later or other breach thereof or as a waiver of any other provision of this Agreement. This Agreement may not be waived, changed, discharged or terminated orally or by any course of dealing between the parties, but only by an instrument in writing signed by the party against whom any waiver, change, discharge or termination is sought.

15. Assignment. Executive may not assign any of his rights or delegate any of his duties or obligations under this Agreement. The rights and obligations of the Company under this Agreement shall inure to the benefit of, and shall be binding upon, the successors and assigns of the Company.
