NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — INTERIM CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related notes that appear in the Annual Report of Forrester Research, Inc. (“Forrester”) as reported on Form 10-K for the year ended December 31, 2005. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations, and cash flows as of the dates and for the periods presented have been included. The results of operations for the nine months ended September 30, 2006 may not be indicative of the results that may be expected for the year ended December 31, 2006, or any other period.

Stock-Based Compensation

Effective January 1, 2006, Forrester adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment “ (“SFAS No. 123R”). All of Forrester’s stock-based compensation is accounted for as equity instruments and Forrester has five equity plans required to be evaluated under SFAS No. 123R: two equity incentive plans, two directors’ stock option plans and an employee stock purchase plan. Under the provisions of SFAS No. 123R, Forrester recognizes the fair value of stock-based compensation in net income over the requisite service period of the individual grantee, which generally equals the vesting period. Prior to January 1, 2006, Forrester followed Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations in accounting for its stock-based compensation.

Forrester has elected the modified prospective transition method for adopting SFAS No. 123R. Under this method, the provisions of SFAS No. 123R apply to all awards granted or modified after the date of adoption. The unrecognized expense of awards not yet vested at the date of adoption is recognized in net income in the periods after the date of adoption using the same valuation method and assumptions determined under the original provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” as disclosed in previous filings. Periods prior to January 1, 2006 will not include compensation costs calculated under the fair value method. Under the provisions of SFAS No. 123R, Forrester recorded approximately $2.5 million and $6.0 million of stock-based compensation in the accompanying consolidated statements of income for the three months and nine months ended September 30, 2006, respectively, included in the following expense categories (in thousands):

	Three Months Ended		Nine Months Ended
	September 30, 2006		September 30, 2006
Cost of services and fulfillment.	$	1,065	$	2,639
Selling and marketing		722		1,709
General and administrative		732		1,695
Total	$	2,519	$	6,043

Forrester utilized the Black-Scholes valuation model for estimating the fair value of the stock-based compensation granted after the adoption of SFAS No. 123R. The weighted-average fair values of the options granted under the stock plans and shares subject to purchase under the employee stock purchase plan were $12.16 and $6.13 for the three months ended September 30, 2006 and $7.58 and $4.78 for the nine months ended September 30, 2006, respectively, using the following assumptions:

6

	Three Months Ended		Three Months Ended		Nine Months Ended		Nine Months Ended
	September 30, 2006		September 30, 2006		September 30, 2006		September 30, 2006
			Employee Stock				Employee Stock
	Stock Option Plans		Purchase Plan		Stock Option Plans		Purchase Plan
Average risk-free interest rate		5.1%		5.3%		4.8%		4.8%
Expected dividend yield	None		None		None		None
Expected life	6.3 Years		0.5 Years		4.0 Years		0.5 Years
Expected volatility		35%		26%		35%		24%

The dividend yield of zero is based on the fact that Forrester has never paid cash dividends and has no present intention to pay cash dividends. Expected volatility is based, in part, on the historical volatility of Forrester’s common stock as well as management’s expectations of future volatility over the expected term of the awards granted. The risk-free interest rate used is based on the U.S. Treasury Constant Maturity rate with an equivalent remaining term. Where the expected term of a stock-based award does not correspond with a term for which the interest rates are quoted, Forrester uses the rate with the maturity closest to the award’s expected term. With the exception of the April 3, 2006 grant referenced below, the expected term assumption is calculated using the simplified method outlined in SEC Staff Accounting Bulletin No. 107.

Based on Forrester’s historical experience for grants with varying vesting terms, estimated forfeiture rates ranging from 0% to 6.5% have been used to determine current period expense. Forrester will record additional expense if the actual forfeiture rate is lower than estimated, and will record recovery of prior expense if the actual forfeiture rate is higher than estimated.

On April 3, 2006, Forrester issued to its employees options to purchase 587,500 shares of common stock (“the April 3, 2006 grant”). These options vest only if certain pro-forma operating margin targets related to full year 2006 performance are achieved. The vesting of these options is over 24 or 36 months, or the options could be forfeited, depending on the actual pro-forma operating margin achieved for 2006. These options do not meet the criteria of “plain vanilla” options and therefore the simplified method for calculating the expected term of these options could not be used. Based on historical exercise patterns for options with similar vesting, Forrester used an expected term of 2 years for the year one vest, 3 years for the year two vest and 4 years for the year three vest to value these options. As of September 30, 2006, Forrester’s management believes that 2006 operating performance will result in the options vesting over 36 months and has recognized the expense to date over that assumed vesting period. Management will adjust compensation expense as necessary based on the actual vesting term at the end of the fourth quarter of 2006.

On March 31, 2005, Forrester issued to its employees options to purchase 940,500 shares of common stock, with vesting contingent upon achievement of certain pro-forma earnings per share (“EPS”) goals for the year ended December 31, 2005. The vesting of these options was over 24 or 36 months, or the options could have been forfeited, depending on the actual pro-forma EPS achieved. Under APB No. 25, these stock options were accounted for as options with variable terms until the achievement of the performance criteria were determinable based upon 2005 financial performance, as the awards contained performance criteria that could have resulted in the forfeiture of all the stock options granted. For the three and nine months ended September 30, 2005, Forrester recorded non-cash stock-based compensation expense of $729,000 and $1.0 million, respectively. The compensation expense represented the vested portion of the intrinsic value of the options granted and was based on an assumed vesting period of 36 months. The total non-cash stock-based compensation expense included in the consolidated statements of income for the three and nine months ended September 30, 2005 is included in the following expense categories (in thousands):

	Three Months Ended		Nine Months Ended
	September 30, 2005		September 30, 2005
Cost of services and fulfillment	$	400	$	559
Selling and marketing		158		221
General and administrative		171		239
Total	$	729	$	1,019

7

SFAS No. 123R requires the presentation of pro forma information for the comparative period prior to the adoption as if all of Forrester’s outstanding stock options and shares subject to purchase under the employee stock purchase plan had been accounted for under the fair value method of the original SFAS No. 123. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based employee compensation to the prior-year period (in thousands, except per-share data).

	Three Months			Nine Months

Diluted income per share — as reported	$	0.12		$	0.36

The weighted-average fair values of the options granted under the stock plans and shares subject to purchase under the employee stock purchase plan were $7.54 and $3.84 for the three months ended September 30, 2005 and $5.90 and $4.03 for the nine months ended September 30, 2005, respectively, using the following assumptions:

	Three Months Ended		Three Months Ended		Nine Months Ended		Nine Months Ended

Expected volatility		46%		21%		46%		25%

The following table summarizes stock option activity under the equity incentive plans and directors’ stock option plans for the nine months ended September 30, 2006 (in thousands, except per share and average life data):

				Weighted		Weighted
				Average		Average Remaining		Aggregate
				Exercise Price		Contractual Life		Intrinsic
	Number of Shares			Per Share		(In Years)		Value

Exercisable as of September 30, 2006		1,648		$	22.30		5.16	$	6,608

The total intrinsic value of options exercised during the nine months ended September 30, 2006 was $19.9 million.

In connection with the adoption of SFAS No. 123R, Forrester was required to change the classification, in the consolidated statements of cash flows, of any tax benefits realized upon the exercise of stock options in excess of that which is associated with the expense recognized for financial reporting purposes. These amounts are presented as a financing cash inflow rather than as a reduction of income taxes paid in the consolidated statements of cash flows.

On November 10, 2005, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position No. FAS 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.” Forrester is considering whether to adopt the alternative transition method provided in the FASB Staff Position for calculating the tax effects of stock-based compensation pursuant to SFAS 123(R). The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (“APIC pool”) related to the tax effects of employee stock-based compensation, and to determine the subsequent impact on the APIC pool and statements of cash flows of the tax effects of employee stock-based compensation awards that were outstanding upon adoption of SFAS 123(R).

Income Taxes

Forrester provides for income taxes on an interim basis according to management’s estimate of the effective tax rate expected to be applicable for the full fiscal year ending December 31.

NOTE 2 — DISCONTINUED OPERATIONS

On September 26, 2006, Forrester completed the sale of its Ultimate Consumer Panel (“UCP”) product line to Lightspeed Online Research, Inc. for $2.5 million in cash of which $2.25 million was paid at the closing date subject to a working capital adjustment, with the remainder due nine months after the closing date. The sale resulted in a gain on the disposal of discontinued operations of $1.4 million, net of $1.0 million of taxes. The sale included the transfer of certain assets, including all UCP customer contracts, historical data, intellectual property, six employees, and licenses as well as certain liabilities arising in the normal course of business. Forrester sold the product line as it was no longer a fit with its core focus on broad, global business and consumer technology data.

In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”), the financial results of the UCP product line are reported as discontinued operations for all periods presented. The UCP Panel product line had revenues for the three months ended September 30, 2006 and 2005 of $537,000 and $431,000, respectively, and revenue for the nine months ended September 30, 2006 and 2005 of $1.8 million and $1.4 million, respectively. Net income from the discontinued operations was $51,000, net of $33,000 of taxes, for the three months ended September 30, 2006 and $300,000, net of $204,000 of taxes, for the nine months ended September 30, 2006. Net loss from the discontinued operations was $82,000, net of $55,000 of tax benefit, for the three months ended September 30, 2005 and $314,000, net of $214,000 of tax benefit, for the nine months ended September 30, 2005.

Net assets and net liabilities of the UCP product line were $447,000 and $974,000 at September 30, 2006, respectively, and $1.3 million and $1.8 million at December 31, 2005, respectively. Net assets consisted primarily of accounts receivable and net liabilities consisted primarily of deferred revenue. The net assets and net liabilities of the discontinued operations were not separately stated on the December 31, 2005 balance sheet as management determined the amounts to be immaterial. The financial results of the UCP product line have been reflected as discontinued operations in the underlying financial statements and related disclosures for all periods presented. The operating results of the UCP product line have previously been included in the Americas operating segment.

NOTE 3 — INTANGIBLE ASSETS

A summary of Forrester’s amortizable intangible assets as of September 30, 2006 is as follows:

	GROSS CARRYING		ACCUMULATED		NET
	AMOUNT		AMORTIZATION		CARRYING AMOUNT

NOTE 4 — REORGANIZATIONS

In November 2003, Forrester acquired the assets of GigaGroup S.A. (“GigaGroup”). In 2004, in connection with the integration of GigaGroup’s operations, Forrester reduced its workforce by approximately 15 positions and vacated and subleased office space. In 2004, Forrester recorded reorganization charges of approximately $2.5 million related to the workforce reduction, approximately $4.7 million related to the excess of contractual lease commitments over the contracted sublease revenue and $1.9 million related to the write-off of related leasehold improvements and furniture and fixtures.

The activity related to the January 2004 reorganization during the nine months ended September 30, 2006 is as follows:

	Accrued as of				Accrued as of
	December 31,		Cash		September 30,
	2005		Payments		2006

Workforce reduction	$	78	$	—	$	78
Facility consolidation and other related costs		2,950		1,616		1,334
Total	$	3,028	$	1,616	$	1,412

The accrued costs related to the 2004 reorganizations are expected to be paid in the following periods:

	TOTAL		2006		2007

Facility consolidation and other related costs		1,334		273		1,061
Total	$	1,412	$	351	$	1,061

In connection with prior reorganizations of its workforce, Forrester has consolidated its office space. As a result of these consolidations, Forrester had aggregate accrued facility consolidation costs of $75,000 as of December 31, 2005. These accrued costs were paid in 2006 and accordingly there was no accrual remaining at September 30, 2006.

NOTE 5 — NET INCOME PER COMMON SHARE

Basic net income per common share for the three and nine months ended September 30, 2006 and 2005 was computed by dividing net income by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share for the three and nine months ended September 30, 2006 and 2005 was computed by dividing net income by the diluted weighted average number of common shares outstanding during the period. The weighted average number of common equivalent shares outstanding has been determined in accordance with the treasury-stock method. Common stock equivalents consist of common stock issuable on the

10

exercise of outstanding options when dilutive. A reconciliation of basic to diluted weighted average shares outstanding is as follows:

	THREE MONTHS ENDED				NINE MONTHS ENDED
	SEPTEMBER 30,				SEPTEMBER 30,
	2006		2005		2006		2005
			(IN THOUSANDS)
Basic weighted average common shares outstanding		22,637		21,287		21,937		21,470
Weighted average common equivalent shares		780		644		747		402
Diluted weighted average shares outstanding		23,417		21,931		22,684		21,872

During the three and nine months ended September 30, 2006 and 2005, approximately 964,000 and 1.1 million and 753,000 and 2.4 million stock options, respectively, were excluded from the calculation of diluted weighted average shares outstanding as the effect would have been anti-dilutive.

NOTE 6 — COMPREHENSIVE INCOME

The components of total comprehensive income for the three and nine months ended September 30, 2006 and 2005 are as follows:

NOTE 7 — NON-MARKETABLE INVESTMENTS

In June 2000, Forrester committed to invest $20.0 million in two technology-related private equity investment funds with capital contributions required to be funded over an expected period of five years. During the three months ended September 30, 2006 and 2005, Forrester contributed approximately $50,000 and $425,000 to these investment funds, respectively. During the nine months ended September 30, 2006 and 2005, Forrester contributed approximately $613,000 and $738,000 to these investment funds, respectively, resulting in total cumulative contributions of approximately $19.4 million to date. One of these investments is being accounted for using the cost method and, accordingly, is valued at cost unless an other than temporary impairment in its value occurs or the investment is liquidated. The other investment is being accounted for using the equity method as Forrester has an ownership interest in the investee in excess of 20% and, accordingly, Forrester records its share of the investee’s operating results each period. During the three and nine months ended September 30, 2006, gross distributions of $175,000 and $673,000, respectively, were recorded and resulted in gains of $119,000 and $488,000, respectively, in the consolidated statements of income. During the three and nine months ended September 30, 2005, gross distributions of $375,000 and $863,000, respectively, were recorded and resulted in gains of $241,000 and $532,000, respectively, in the consolidated statements of income. During the three and nine months ended September 30, 2006 and 2005 there were no impairments recorded. During the three months and nine months ended September 30, 2006 and 2005, fund management charges of approximately $84,000 and $253,000, respectively, were included in other income, net for each period in the consolidated statements of income, bringing the total cumulative fund management charges paid by Forrester to approximately $2.5 million as of September 30, 2006. Fund management charges are recorded as a reduction of the investments’ carrying value.

11

In December 2003, Forrester committed to invest an additional $2.0 million in an annex fund of one of the two private equity investment funds. As of September 30, 2006, $2.0 million had been contributed to the annex fund. The annex fund investment is outside the scope of the bonus plan described below. This investment is being accounted for using the cost method and, accordingly, is valued at cost unless an other than temporary impairment in its value occurs or the investment is liquidated. In the nine months ended September 30, 2006, Forrester determined that its investment had been permanently impaired. As a result, Forrester recorded write-downs of approximately $183,000 which were included in realized gains on securities, net, in the consolidated statements of income.

In March 2000, Forrester invested $1.0 million in the common stock of Doculabs, Inc. (“Doculabs”), an independent technology research firm. In March 2001, Forrester invested an additional $2.0 million, resulting in approximately a 10.4% ownership interest in Doculabs. This investment is being accounted for using the cost method and, accordingly, is being valued at cost unless an impairment in its value that is other than temporary occurs or the investment is liquidated. During the three and nine months ended September 30, 2006 and 2005 there were no impairments recorded. During the three months ended September 30, 2006 Forrester received an approximate $67,000 cash dividend which was recorded as a reduction of the investment’s carrying value.

Forrester has adopted a cash bonus plan to pay bonuses, after the return of invested capital, measured by the proceeds of a portion of its share of net profits from these investments, if any, to certain key employees, subject to the terms and conditions of the plan. The payment of such bonuses would result in compensation expense with respect to the amounts so paid. To date, no bonuses have been paid under this plan. The principal purpose of this cash bonus plan was to retain key employees by allowing them to participate in a portion of the potential return from Forrester’s technology-related investments if they remained employed by the Company. The plan was established at a time when technology and internet companies were growing significantly, and providing incentives to retain key employees during that time was important.

The timing of the recognition of future gains or losses from these investment funds is beyond Forrester’s control. As a result, it is not possible to predict when Forrester will recognize any gains or losses, if Forrester will award cash bonuses based on the net profit from such investments, or when Forrester will incur compensation expense in connection with the payment of such bonuses. If the investment funds realize large gains or losses on their investments, Forrester could experience significant variations in its quarterly results unrelated to its business operations. These variations could be due to significant gains or losses or to significant compensation expenses. While gains may offset compensation expenses in a particular quarter, there can be no assurance that related gains and compensation expenses will occur in the same quarters.

NOTE 8 — STOCK REPURCHASE

In October 2001, Forrester announced a program authorizing the repurchase of up to $50 million of its common stock. In February 2005, the Board of Directors authorized the repurchase of up to an additional $50.0 million of common stock. The shares repurchased may be used, among other things, in connection with Forrester’s stock plans and for potential acquisitions. As of September 30, 2006, Forrester had repurchased approximately 4.8 million shares of common stock at an aggregate cost of approximately $85.8 million.

NOTE 9 — OPERATING SEGMENT AND ENTERPRISE WIDE REPORTING

Forrester’s operations are managed within the following three operating groups (“Operating Groups”): (i) Americas, (ii) Europe, Middle East and Africa (EMEA) and (iii) Asia Pacific. All of the Operating Groups generate revenues through sales of the same research and advisory and other service offerings. Each of the Operating Groups is composed of sales forces responsible for clients located in such Operating Group’s region and research personnel focused primarily on issues generally more relevant to clients in that region. Forrester evaluates reportable segment performance and allocates resources based on direct margin. Direct margin, as presented below, is defined as operating income excluding certain selling and marketing expenses, non-cash stock-based compensation expense, general and administrative expenses, depreciation expense and amortization of intangibles. The accounting policies used by the reportable segments are the same as those used by Forrester.

Forrester does not identify or allocate assets, including capital expenditures, by operating segment. Accordingly, assets are not being reported by segment because the information is not available by segment and is not reviewed in the evaluation of performance or in making decisions in the allocation of resources.

NOTE 10 — RECENT ACCOUNTING PRONOUNCEMENTS

In July 2006, the FASB issued FIN 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109,” which seeks to reduce the significant diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006. Upon adoption, the cumulative effect of any changes in net assets resulting from the application of FIN 48 will be recorded as an adjustment to retained earnings. Forrester is currently evaluating the impact, if any, that FIN 48 will have on its financial position and results of operations.

In September 2006, the SEC issued Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” to provide guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of the materiality assessment. Under SAB No. 108, companies should evaluate a misstatement based on its impact on the current year income statement, as well as the cumulative effect of correcting such misstatements that existed in prior years existing in the current year’s ending balance sheet. SAB No. 108 is effective for fiscal years ending after November 15, 2006. We have not yet determined the effect the adoption of SAB No. 108 will have on our financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The standard applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. The standard does not expand on the use of fair value in any new circumstances. SFAS No. 157 is effective for financial statements issued for fiscal years beginning November 15, 2007, and interim periods within those fiscal years. We have not yet determined the effect the adoption of SFAS No. 157 will have on our financial position, results of operations or cash flows.

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

OVERVIEW

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects,” “believes,” “anticipates,” “intends,” “plans,” “estimates,” or similar expressions are intended to identify these forward-looking statements. These statements include, but are not limited to, statements about the success of and demand for our research and advisory products and services, and our ability to achieve success as the industry consolidates. These statements are based on our current plans and expectations and involve risks and uncertainties that could cause actual future activities and results of operations to be materially different from those set forth in the forward-looking statements. Important factors that could cause actual future activities and results to differ include, among others, trends in technology spending, business and economic conditions, market trends, competition, the ability to attract and retain professional staff, our dependence on renewals of our membership-based research services and on key personnel, as well as risks associated with our ability to offer new products and services, variations in our quarterly operating results, and the actual amount of the charge and any cost savings related to reductions in force and associated actions. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events, or otherwise.

We derive revenues from memberships to our research product offerings and from our advisory services and events available through what we refer to as Research, Data, Consulting, and Community offerings. We offer contracts for our research products that are typically renewable annually and payable in advance. Research revenues are recognized as revenue ratably over the term of the contract. Accordingly, a substantial portion of our billings are initially recorded as deferred revenue. Clients purchase advisory services offered through our Data, Consulting and Community products and services to supplement their memberships to our research. Billings attributable to advisory services are initially recorded as deferred revenue and are recognized as revenue when the services are delivered. Event billings are also initially recorded as deferred revenue and are recognized as revenue upon completion of each

14

event. Consequently, changes in the number and value of client contracts, both net decreases as well as net increases, impact our revenues and other results over a period of several months.

Our primary operating expenses consist of cost of services and fulfillment, selling and marketing expenses, general and administrative expenses, depreciation, and amortization of intangible assets. Cost of services and fulfillment represents the costs associated with the production and delivery of our products and services, and it includes the costs of salaries, bonuses, and related benefits for research personnel and all associated editorial, travel, and support services. Selling and marketing expenses include salaries, employee benefits, travel expenses, promotional costs, sales commissions, and other costs incurred in marketing and selling our products and services. General and administrative expenses include the costs of the technology, operations, finance, and strategy groups and our other administrative functions. Overhead costs are allocated over these categories according to the number of employees in each group. Amortization of intangible assets represents the cost of amortizing acquired intangible assets such as customer relationships.

Deferred revenue, agreement value, client retention, dollar retention and enrichment are metrics we believe are important to understanding our business. We believe that the amount of deferred revenue, along with the agreement value of contracts to purchase research and advisory services, provide a significant measure of our business activity. Deferred revenue reflects billings in advance of revenue recognition as of the measurement date. We calculate agreement value as the total revenues recognizable from all research and advisory service contracts in force at a given time (but not including advisory-only contracts), without regard to how much revenue has already been recognized. No single client accounted for more than 3% of agreement value at September 30, 2006 or 2005. We calculate client retention as the number of client companies who renewed with memberships during the most recent twelve month period as a percentage of those that would have expired during the same period. We calculate dollar retention as a percentage of the dollar value of all client membership contracts renewed during the most recent twelve month fiscal period to the total dollar value of all client membership contracts that expired during the period. We calculate enrichment as a percentage of the dollar value of client membership contracts renewed during the period to the dollar value of the corresponding expiring contracts. Client retention, dollar retention, and enrichment are not necessarily indicative of the rate of future retention of our revenue base. A summary of our key metrics is as follows:

	As of						Absolute			Percentage
	September 30,						Increase			Increase
	2006			2005			(Decrease)			(Decrease)
Deferred Revenue (in millions)	$	74.9		$	67.7		$	7.2			11	%
Agreement Value (in millions)	$	158.7		$	133.9		$	24.8			19	%
Client Retention		79	%		78	%		1	%		1	%
Dollar Retention		87	%		88	%		(1	)%		(1	)%
Enrichment		110	%		105	%		5	%		5	%
Number of clients		2,273			1,957			316			16	%

The increase in deferred revenue and agreement value from September 30, 2005 to September 30, 2006 is primarily due to increases in the number of clients and in the average contract size of research only contracts. The average contract size for annual memberships for research only contracts at September 30, 2006 was approximately $42,000, an increase of 5% from $40,000 at September 30, 2005. Increases in average contract sizes and enrichment in 2006 reflect increasing demand for our products, reduced discounting and increased prices.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 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 ongoing basis, we evaluate our policies and estimates,

15

including but not limited to, those related to our revenue recognition, non-cash stock-based compensation, allowance for doubtful accounts, non-marketable investments, goodwill and other intangible assets and income taxes. Management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We consider the following accounting policies to be those that require the most subjective judgment or those most important to the portrayal of our financial condition and results of operations. If actual results differ significantly from management’s estimates and projections, there could be a material effect on our financial statements. This is not a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP, with no need for management’s judgment in its application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. For further discussion of the application of these and our other accounting policies, see Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2005, previously filed with the SEC.

• REVENUE RECOGNITION. We generate revenues from licensing research, performing advisory services, hosting events and selling annual memberships. We execute contracts that govern the terms and conditions of each arrangement. Revenues from contracts that contain multiple deliverables are allocated among the separate units based on their relative fair values, the estimate of which requires us to make estimates of such fair values; however, the amount recognized is limited to the amount that is not contingent on future performance conditions. Research service revenues are recognized ratably over the term of the agreement. Advisory service revenues are recognized during the period in which the customer receives the agreed upon deliverable. Forrester Teleconferences revenue and reimbursed out of pocket expenses are recorded as advisory service revenues. Event revenues are recognized upon completion of the event. Annual memberships which include access to our research, unlimited phone or email analyst inquiry, unlimited participation in Forrester’s Teleconferences, and the right to attend one event, are accounted for as one unit of accounting and recognized ratably as research services revenue over the membership period. While our historical business practice had been to offer contracts with a non-cancelable term, effective April 1, 2005, we began to offer our clients a money back guarantee, which gives them the right to cancel their contracts prior to the end of the contract term. For contracts that are terminated during the contract term, refunds would be issued for unused products or services. Furthermore, our revenue recognition determines the timing of commission expenses that are deferred and recorded as expense as the related revenue is recognized. We evaluate the recoverability of deferred commissions at each balance sheet date.

• NON-CASH STOCK-BASED COMPENSATION. Effective January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”). SFAS No. 123R requires the recognition of the fair value of stock-based compensation in net income. To determine the fair value, SFAS No. 123R requires significant judgment and the use of estimates, particularly surrounding assumptions such as stock price volatility and expected option lives and expected option forfeiture rates, to value equity-based compensation. SFAS No. 123R also requires us to estimate future forfeitures of stock-based compensation. There is little experience or guidance with respect to developing these assumptions and models. There is also uncertainty as to how the standard will be interpreted and applied as more companies adopt the standard, and companies and their advisors gain experience with applying the standard.

• ALLOWANCE FOR DOUBTFUL ACCOUNTS. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make contractually obligated payments that totaled approximately $699,000 as of September 30, 2006. Management specifically analyzes accounts receivable and historical bad debts, customer concentrations, current economic trends, and changes in our customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required, and if the financial condition of our customers were to improve, the allowances may be reduced accordingly.

16

• NON-MARKETABLE INVESTMENTS. We hold minority interests in technology-related companies and equity investment funds. These investments are in companies that are not publicly traded, and, therefore, because no established market for these securities exists, the estimate of the fair value of our investments requires significant judgment. We have a policy in place to review the fair value of our investments on a regular basis to evaluate the carrying value of the investments in these companies which consists primarily of reviewing the investee’s revenue and earnings trends relative to predefined milestones and overall business prospects. We record impairment charges when we believe that an investment has experienced a decline in value that is other than temporary. Future adverse changes in market conditions or poor operating results of underlying investments could result in losses or an inability to recover the carrying value of the investments that may not be reflected in an investment’s current carrying value, thereby possibly requiring an impairment charge in the future.

• GOODWILL AND INTANGIBLE ASSETS AND OTHER LONG-LIVED ASSETS. We have goodwill and identified intangible assets with finite lives related to our acquisitions. SFAS No. 142, “Goodwill and Other Intangible Assets,” requires that goodwill and intangible assets with indefinite lives no longer be amortized but instead be measured for impairment at least annually or whenever events indicate that there may be an impairment. In order to determine if an impairment exists, we compare the reporting unit’s carrying value to the reporting unit’s fair value. Determining the reporting unit’s fair value requires us to make estimates on our market conditions and operational performance. Absent an event that indicates a specific impairment may exist, we have selected November 30th as the date of performing the annual goodwill impairment test. As of September 30, 2006, we believe that the carrying value of our goodwill is not impaired. Future events could cause us to conclude that impairment indicators exist and that goodwill associated with our acquired businesses is impaired. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations.

Intangible assets with finite lives are valued according to the future cash flows they are estimated to produce. These assigned values are amortized on an accelerated basis which matches the periods those cash flows are estimated to be produced. Tangible assets with finite lives consist of property and equipment, which are depreciated and amortized over their estimated useful lives. We continually evaluate whether events or circumstances have occurred that indicate that the estimated remaining useful life of our identifiable intangible and long-lived tangible assets may warrant revision or that the carrying value of these assets may be impaired. To compute whether intangible assets have been impaired, the estimated undiscounted future cash flows for the estimated remaining useful life of the assets are compared to the carrying value. To the extent that the future cash flows are less than the carrying value, the assets are written down to the estimated fair value of the asset.

• INCOME TAXES. We have deferred tax assets related to temporary differences between the financial statement and tax bases of assets and liabilities as well as operating loss carryforwards (primarily from stock option exercises and the acquisition of Giga Information Group). In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and before the carryforwards expire. Although realization is not assured, based upon the level of our historical taxable income and projections for our future taxable income over the periods during which the deferred tax assets are deductible and the carryforwards expire, management believes it is more likely than not that we will realize the benefits of these deferred tax assets. The amount of the deferred tax asset considered realizable, however, could be reduced if our estimates of future taxable income during the carry-forward periods are incorrect. In July 2006, the FASB issued FIN 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109,” which seeks to reduce the significant diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006. Upon adoption, the cumulative effect of any changes in net assets resulting from the application

17

of FIN 48 will be recorded as an adjustment to retained earnings. We are currently evaluating the impact, if any, that FIN 48 will have on our financial position and results of operations.

The increase in total revenues is attributable to increased demand for certain of our syndicated research products, reduced discounting and increased prices. Advisory services and other revenues increased 3% due to two events having been held in the third quarter of 2006, compared with one event in the comparable period in 2005.

International revenues increased 11% to $12.5 million in the three months ended September 30, 2006 from $11.3 million in the three months ended September 30, 2005 primarily due to the effects of foreign currency translation.

The decrease in international revenues as a percentage of total revenues is primarily attributable to sales of our products and services growing at a faster rate domestically than internationally.

The increase in general and administrative expenses is primarily attributable to increased compensation and benefits costs resulting from an increase in average headcount, the recording of non-cash stock-based compensation expense related to the adoption of SFAS No. 123R and annual increases in compensation costs.

DEPRECIATION. Depreciation expense increased 10% to $947,000 in the three months ended September 30, 2006 from $859,000 in the three months ended September 30, 2005. The increase is primarily attributable to depreciation expense related to purchases of computer equipment and leasehold improvements during 2005 and 2006.

AMORTIZATION OF INTANGIBLE ASSETS. Amortization of intangible assets decreased 40% to $474,000 in the three months ended September 30, 2006 from $786,000 in the three months ended September 30, 2005. This decrease in amortization expense is attributable to the accelerated method we are using to amortize our acquired intangible assets according to the expected cash flows to be received from these assets.

OTHER INCOME, NET. Other income, net, consisting primarily of interest income, increased 135% to $1.7 million in the three months ended September 30, 2006 from $722,000 in the three months ended September 30, 2005. The increase is primarily due to an increase in the average cash and investment balances available for investment in 2006 as compared to 2005 and to higher returns on invested capital.

REALIZED GAINS ON SECURITIES, NET. Gains on distributions from non-marketable investments totaled $119,000 and $241,000 in the three months ended September 30, 2006 and 2005, respectively. Impairments of non-marketable investments resulted in a charge of $21,000 during the three months ended September 30, 2006.

PROVISION FOR INCOME TAXES. During the three months ended September 30, 2006, we recorded an income tax provision of $2.8 million on income from continuing operations, which reflected an effective tax rate of 42%. During the three months ended September 30, 2005, we recorded an income tax provision of $2.5 million on income from continuing operations, which reflected an effective tax rate of 49%. The decrease in our effective tax rate for Q3 2006 resulted from a revised estimate of the full year 2006 effective tax rate to 46% from 49% during the third quarter of 2006.

The increase in total revenues is attributable to increased demand for certain of our syndicated research products, reduced discounting and increased prices. The increase in advisory services and other revenues is principally due to six events having been held in the nine months ended September 30, 2006, compared with five events in the comparable period in 2005, as well as increased demand for our consulting services.

International revenues increased 15% to $39.0 million in the nine months ended September 30, 2006 from $33.9 million in the nine months ended September 30, 2005 primarily due to increased demand for our products internationally.

DEPRECIATION. Depreciation expense increased 4% to $2.7 in the nine months ended September 30, 2006 from $2.6 million in the nine months ended September 30, 2005. The increase is primarily attributable to depreciation expense related to purchases of computer equipment and leasehold improvements during 2005 and 2006.

AMORTIZATION OF INTANGIBLE ASSETS. Amortization of intangible assets decreased 41% to $1.6 million in the nine months ended September 30, 2006 from $2.7 million in the nine months ended September 30, 2005. This decrease in amortization expense is attributable to the accelerated method we are using to amortize our acquired intangible assets according to the expected cash flows to be received from these assets.

OTHER INCOME, NET. Other income, net, consisting primarily of interest income, increased 77% to $3.9 million in the nine months ended September 30, 2006 from $2.2 million in the nine months ended September 30, 2005. The increase is primarily due to an increase in the average cash and investment balances available for investment in 2006 as compared to 2005 and to higher returns on invested capital.

REALIZED GAINS ON SECURITIES, NET. Gains on distributions from non-marketable investments totaled approximately $488,000 and $532,000 during the nine months ended September 30, 2006 and 2005, respectively. Impairments of non-marketable investments resulted in a charge of $183,000 during the nine months ended September 30, 2006. In the three months ended March 31, 2005, we sold the remaining total of approximately 89,000 shares of Greenfield Online, Inc. (“Greenfield”), an Internet-based market research firm that we held an

21

approximately 1.1% ownership interest in prior to their initial public offering in July, 2004. As a result of the sale we received net proceeds of approximately $1.7 million and recognized a gain of approximately $1.5 million.

PROVISION FOR INCOME TAXES. During the nine months ended September 30, 2006, we recorded an income tax provision of $7.5 million on income from continuing operations, which reflected an effective tax rate of 46%. During the nine months ended September 30, 2005, we recorded an income tax provision of $6.2 million on income from continuing operations, which reflected an effective tax rate of 43%. The increase in our effective tax rate for fiscal year 2006 resulted primarily from the creation of a permanent tax difference for the projected annual non-cash stock-based compensation expense related to the adoption of SFAS No. 123R.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations primarily through funds generated from operations. Memberships for research services, which constituted approximately 64% of our revenues during the nine months ended September 30, 2006, are annually renewable and are generally payable in advance. We generated cash from operating activities of $35.8 million and $18.7 million during the nine months ended September 30, 2006 and 2005, respectively. The increase in cash provided from operations is primarily attributable to the increase in cash received from payment of accounts receivable.

During the nine months ended September 30, 2006, we used $76.7 million of cash in investing activities, consisting primarily of $76.4 million used in net purchases of available-for-sale securities. During the nine months ended September 30, 2005, we generated $4.8 million of cash from investing activities, consisting primarily of $6.2 million received from net sales of marketable securities, offset by $2.4 million for capital expenditures. We regularly invest excess funds in short-and intermediate-term interest-bearing obligations of investment grade.

In June 2000, we committed to invest $20.0 million in two private equity investment funds over an expected period of five years. As of September 30, 2006, we had contributed approximately $19.4 million to the funds. The timing and amount of future contributions are entirely within the discretion of the investment funds. In July 2000, we adopted a cash bonus plan to pay bonuses, after the return of invested capital, measured by the proceeds of a portion of the share of net profits from these investments, if any, to certain key employees who must remain employed with us at the time any bonuses become payable under the plan, subject to the terms and conditions of the plan. The principal purpose of this cash bonus plan was to retain key employees by allowing them to participate in a portion of the potential return from Forrester’s technology-related investments if they remained employed by the Company. The plan was established at a time when technology and internet companies were growing significantly, and providing incentives to retain key employees during that time was important. To date, we have not paid any bonuses under this plan.

In December 2003, we committed to invest an additional $2.0 million over an expected period of two years in an annex fund of one of the two private equity investment funds. As of September 30, 2006, we had contributed $2.0 million to the annex fund.

We generated cash from financing activities of $23.5 million during the nine months ended September 30, 2006 and we used $7.8 million of cash in financing activities during the nine months ended September 30, 2005. The increase in cash provided from financing activities is primarily attributable to an increase in proceeds from exercises of employee stock options and a decrease in repurchases of our common stock.

In October 2001, Forrester announced a program authorizing the repurchase of up to $50.0 million of its common stock. In February 2005, our Board of Directors authorized an additional $50.0 million to purchase common stock under the stock repurchase program. During the three months ended September 30, 2006, we repurchased approximately 335,000 shares of common stock at an aggregate cost of approximately $9.4 million. As of September 30, 2006, we had cumulatively repurchased approximately 4.8 million shares of common stock at an aggregate cost of approximately $85.8 million.

As of September 30, 2006, we had cash and cash equivalents of $31.6 million and available-for-sale securities of $159.9 million. We do not have a line of credit and do not anticipate the need for one in the foreseeable future. We plan to continue to introduce new products and services and expect to make minimal investments in our

22

infrastructure during the next 12 months. We believe that our current cash balance, available-for-sale securities, and cash flows from operations will satisfy working capital, financing activities, and capital expenditure requirements for at least the next two years.

As of September 30, 2006, we had future contractual obligations as follows for operating leases:

	FUTURE PAYMENTS DUE BY YEAR
CONTRACTUAL OBLIGATIONS*	TOTAL		2006		2007		2008		2009		2010		Thereafter
	(IN THOUSANDS)
Operating leases	$	34,150	$	1,675	$	8,670	$	6,819	$	6,752	$	6,618	$	3,616

* The above table does not include future minimum rentals to be received under subleases of $596,000. The above table also does not include the remaining $650,000 of capital commitments to the private equity funds described above due to the uncertainty as to the timing of capital calls made by such funds.

We do not maintain any off-balance sheet financing arrangements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about our market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use derivative financial instruments for speculative or trading purposes.

INTEREST RATE SENSITIVITY. We maintain an investment portfolio consisting mainly of federal, state and municipal government obligations and corporate obligations, with a weighted-average maturity of less than one year. These available-for-sale securities are subject to interest rate risk and will decline in value if market interest rates increase. We have the ability to hold our fixed income investments until maturity (except for any future acquisitions or mergers). Therefore, we would not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates on our securities portfolio. The following table provides information about our investment portfolio. For investment securities, the table presents principal cash flows and related weighted-average interest rates by expected maturity dates.

Principal amounts by expected maturity in U.S. dollars (in thousands) are as follows:

	FAIR VALUE
	AT
	SEPTEMBER 30, 2006			FY 2006			FY 2007			FY 2008			FY 2009

Weighted average interest rate		3.70	%		3.77	%		3.47	%		3.67	%		3.62	%

FOREIGN CURRENCY EXCHANGE. On a global level, we face exposure to movements in foreign currency exchange rates. This exposure may change over time as business practices evolve and could have a material adverse impact on our results of operations. To date, the effect of changes in currency exchange rates has not had a significant impact on our financial position or our results of operations. Accordingly, we have not entered into any hedging agreements. However, we are prepared to hedge against fluctuations that the Euro, or other foreign currencies, will have on foreign exchange exposure if this exposure becomes material. As of September 30, 2006,

23

the total assets related to non-U.S. dollar denominated currencies that are subject to foreign currency exchange risk were approximately $23.3 million.

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of September 30, 2006. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable SEC rules and forms and were effective.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended September 30, 2006 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

     5. Withholding.

     6. Termination. Notwithstanding Paragraph 3 above, this Option, to the extent unexercised, shall terminate immediately upon the earliest to occur of the following:

     (a) The Expiration Date of the Option;

     (b) The expiration of three months from the date of termination of the Holder’s employment by the Company or any of its subsidiaries (other than a termination described in subparagraph (c), (d), or (e) below); provided, that if the Holder shall die during such three-month period, the time of termination of the unexercised portion of the Option shall be determined under the provisions of subparagraph (d) below, subject to subparagraph (a) above;

     (c) The expiration of one year from the date of termination of the employment of the Holder due to permanent and total disability within the meaning of Section 22(e)(3) of the Internal Revenue Code of 1986, as amended (other than a termination described in subparagraph (e) below);

     (d) The expiration of one year following the Holder’s death if it occurs while Holder is employed by the Company or its subsidiaries; or

     (e) The termination of the Holder’s employment by the Company or any of its subsidiaries if such termination constitutes or is attributable to a breach by the Holder of an employment agreement with the Company or its subsidiaries, or if the Holder is discharged for cause. The Committee shall have the right to determine whether the Holder has been discharged for breach or for cause and the date of such discharge, and such determination of the Committee shall be final and conclusive.

     7. Reservation of Shares. The Company hereby agrees that at all times there shall be reserved for issuance and/or delivery upon exercise of the Option such number of Shares as shall be required for issuance or delivery upon exercise hereof.

     8. Rights of Holder. Nothing contained herein shall be construed to confer upon the Holder any right to be continued in the employ of the Company or any of its subsidiaries, or derogate from the right of the Company or any of its Subsidiaries to retire, request the resignation of, or discharge the Holder at any time, with or without cause. The Holder shall not, by virtue hereof, be entitled to any rights of a stockholder in the Company or its subsidiaries, either at law or equity, and the rights of the Holder are limited to those expressed herein and in the Plan and are not enforceable against the Company or its subsidiaries, except to the extent set forth herein.

     9. Exclusion from Pension Computations. By acceptance of the grant of the Option, the Holder hereby agrees that any income realized upon the receipt or exercise hereof, or upon the disposition of the Shares received upon its exercise, is special incentive compensation and will not be taken into account as “wages,” “salary,” or “compensation” in determining the amount of any payment under any pension, retirement, incentive, profit-sharing, bonus, or deferred compensation plan of the Company, or its subsidiaries.

     10. Registration; Legend. Without limiting the generality of Section 8 of the Plan, the Company may postpone the issuance and delivery of Shares upon any exercise of the Option until (a) the admission of such Shares to listing on any stock exchange or exchanges on which Shares of the Company of the same classes are then listed and (b) the completion of such registration or other qualification of such Shares under any state or federal law, rule or regulation as the Company shall determine to be necessary or advisable. The Holder shall make such representations and furnish such information as, in the opinion of counsel for the Company, may be appropriate to permit the Company to issue the Shares in compliance with the provisions of the Securities Act of 1933, as amended, or any comparable act. The Company may cause an appropriate legend to be set forth on each certificate representing Shares or any other security issued or issuable upon exercise of the Option unless counsel for the Company is of the opinion as to any such certificate that a legend is unnecessary.

     11. Amendment. The Committee may, with the consent of the Holder in the case of an amendment that adversely affects the Holder’s rights under the Option, at any time or from time to time, amend the terms and conditions of the Option.

     12. Notices. Any notice which either party hereto may be required or permitted to give to the other shall be in writing, and may be delivered personally or by mail, postage prepaid, addressed as follows: to the Company, at its office at 400 Technology Square, Cambridge, Massachusetts 02139, or at such other address as the Company by notice to the Holder may designate in writing from time to time; to the Holder, at the address shown below his signature on this Option certificate, or at such other address as the Holder by notice to the Company may designate in writing from time to time. Notices shall be effective upon receipt.

     13. Incorporation of Plan; Interpretation. The Option and this Option certificate are issued pursuant to and are subject to all of the terms and conditions of the Plan, the terms, conditions, and definitions of which are hereby incorporated as though set forth at length, and the receipt of a copy of which the Holder hereby acknowledges by his signature below.

Issued Pursuant to the Forrester Research, Inc. 2006 Equity Incentive Plan (“Plan”)

     THIS CERTIFIES that on ___XX, 200___(“Issuance Date”) First Last (the “Holder”) was granted an option (the “Option” or this “Option”) to purchase all or any part of X,XXX fully paid and non-assessable shares (“Shares”) of Common Stock (par value of $.01 per share) of Forrester Research, Inc.

     1. Nature of Option. This Option is to be treated for all purposes as an option that does not qualify as an incentive stock option as defined in Section 422 of the Code. This Option is intended not to constitute or provide for “nonqualified deferred compensation” subject to Section 409A of the Code. The right and option to purchase shares hereby granted shall be exercisable as provided in Paragraph 3 hereof, in accordance with the determination made by the Compensation and Nominating Committee (the “Committee”) of the Company’s Board of Directors administering the Plan.

     2. Expiration. This Option shall expire on X, 20___(“Expiration Date”).

     3. Vesting and Exercise. This Option may be exercised or surrendered during the Holder’s lifetime only by the Holder. This Option shall not be transferable by the Holder otherwise than by will or by the laws of descent and distribution.

     Except as provided below in this Paragraph 3, this Option will not vest and may not be exercised unless the Holder shall have been continuously employed by the Company or any of its subsidiaries for a period of twelve (12) months after the Issuance Date with regard to one-fourth of the total Shares that can be purchased under the Option (rounded to the nearest whole Share), for twenty-four (24) months after the Issuance Date with regard to an additional one-fourth of the total Shares under the Option (rounded to the nearest whole Share), for thirty-six (36) months after the Issuance Date with regard to an additional one-fourth of the total Shares under the Option (rounded to the nearest whole Share), and for forty-eight (48) months after the Issuance Date for the balance of the total Shares under the Option. Upon and after such dates, the applicable portion of this Option shall vest and shall be exercisable. Except as otherwise permitted herein, if the Holder’s employment is terminated prior to the full vesting of the Option, all rights with respect to any unvested portion shall be forfeited and the remaining portion shall remain exercisable, if at all, in accordance with Paragraph 6 below.

     Notwithstanding the foregoing, the unvested portion of this Option shall vest to the extent, if any, provided in and in accordance with the provisions of Section 7(a) of the Plan (pertaining to “Covered Transactions”) in the circumstances described in said Section 7(a).

page 1

     This Option shall be exercised by the delivery of a written notice duly signed by the Holder, together with this Option certificate, and the full purchase price of the Shares purchased pursuant to the exercise of this Option, to the Committee or an officer of the Company appointed by the Committee for the purpose of receiving the same. This Option may not be exercised at any time when such Option, or the exercise or payment thereof, may result in the violation of any law or governmental order or regulation.

     Payment for the Shares purchased pursuant to the exercise of this Option shall be made in full at the time of the exercise of the Option (a) by check payable to the Company, or (b) by delivery of an unconditional and irrevocable undertaking by a broker to deliver promptly to the Company sufficient funds to pay the exercise price.

     4. Delivery of Shares. Within a reasonable time after the exercise of the Option, the Company shall cause to be delivered to the person entitled thereto the number of Shares purchased pursuant to the exercise of the Option.

     5. Withholding. In the event that the Holder elects to exercise this Option or any part thereof, and if the Company or its subsidiaries shall be required to withhold any amount by reason of any federal, state, or local tax rules or regulations in respect of the issuance of Shares to the Holder pursuant to the Option, the Company or any such subsidiary shall be entitled to satisfy such withholding obligations in accordance with the terms of Section 6 of the Plan.

     6. Termination. Notwithstanding Paragraph 3 above, this Option, to the extent unexercised, shall terminate immediately upon the earliest to occur of the following:

     (a) The Expiration Date of the Option;

     (b) The expiration of three months from the date of termination of the Holder’s employment by the Company or any of its subsidiaries (other than a termination described in subparagraph (c), (d), or (e) below); provided, that if the Holder shall die during such three-month period, the time of termination of the unexercised portion of the Option shall be determined under the provisions of subparagraph (d) below, subject to subparagraph (a) above;

     (c) The expiration of one year from the date of termination of the employment of the Holder due to permanent and total disability within the meaning of Section 22(e)(3) of the Internal Revenue Code of 1986, as amended (other than a termination described in subparagraph (e) below);

     (d) The expiration of one year following the Holder’s death if it occurs while Holder is employed by the Company or its subsidiaries; or

     (e) The termination of the Holder’s employment by the Company or any of its subsidiaries if such termination constitutes or is attributable to a breach by the Holder of an employment agreement with the Company or its subsidiaries, or if the Holder is discharged for cause. The Committee shall have the right to determine whether the Holder has been discharged for breach or for cause and the date of such discharge, and such determination of the Committee shall be final and conclusive.

     7. Reservation of Shares. The Company hereby agrees that at all times there shall be reserved for issuance and/or delivery upon exercise of the Option such number of Shares as shall be required for issuance or delivery upon exercise hereof.

     8. Rights of Holder. Nothing contained herein shall be construed to confer upon the Holder any right to be continued in the employ of the Company or any of its subsidiaries, or derogate from the right of the Company or any of its Subsidiaries to retire, request the resignation of, or discharge the Holder at any time, with or without cause. The Holder shall not, by virtue hereof, be entitled to any rights of a stockholder in the Company or its subsidiaries, either at law or equity, and the rights of the Holder are limited to those expressed herein and in the Plan and are not enforceable against the Company or its subsidiaries, except to the extent set forth herein.

     9. Exclusion from Pension Computations. By acceptance of the grant of the Option, the Holder hereby agrees that any income realized upon the receipt or exercise hereof, or upon the disposition of the Shares received upon its exercise, is special incentive compensation and will not be taken into account as “wages,” “salary,” or “compensation” in determining the amount of any payment under any pension, retirement, incentive, profit-sharing, bonus, or deferred compensation plan of the Company, or its subsidiaries.

     10. Registration; Legend. Without limiting the generality of Section 8 of the Plan, the Company may postpone the issuance and delivery of Shares upon any exercise of the Option until (a) the admission of such Shares to listing on any stock exchange or exchanges on which Shares of the Company of the same classes are then listed and (b) the completion of such registration or other qualification of such Shares under any state or federal law, rule or regulation as the Company shall determine to be necessary or advisable. The Holder shall make such representations and furnish such information as, in the opinion of counsel for the Company, may be appropriate to permit the Company to issue the Shares in compliance with the provisions of the Securities Act of 1933, as amended, or any comparable act. The Company may cause an appropriate legend to be set forth on each certificate representing Shares or any other security issued or issuable upon exercise of the Option unless counsel for the Company is of the opinion as to any such certificate that a legend is unnecessary.

     11. Amendment. The Committee may, with the consent of the Holder in the case of an amendment that adversely affects the Holder’s rights under the Option, at any time or from time to time, amend the terms and conditions of the Option.

     12. Notices. Any notice which either party hereto may be required or permitted to give to the other shall be in writing, and may be delivered personally or by mail, postage prepaid, addressed as follows: to the Company, at its office at 400 Technology Square, Cambridge, Massachusetts 02139, or at such other address as the Company by notice to the Holder may designate in writing from time to time; to the Holder, at the address shown below his signature on this Option certificate, or at such other address as the Holder by notice to the Company may designate in writing from time to time.

page 3

interpretation of the provisions of this Option and of the Plan shall be final. The Committee may authorize and establish such rules, regulations, and revisions thereof not inconsistent with the provisions of the Plan, as it may deem advisable.

     IN WITNESS WHEREOF, the parties have signed this certificate on the date first above written.
