PART I ITEM 1. BUSINESS FactSet Research Systems Inc. ("the Company" or "FactSet") is a leading provider of online integrated database services to the global financial community. The Company provides a comprehensive, one-stop source of financial information and analytics for investment managers, investment bankers, and other financial professionals. FactSet combines over 100 databases into a single mainframe information system which is accessible by clients through their personal computers. The Company acquires financial information from over 30 database vendors and when possible, strives to maintain contractual relationships with a minimum of two database providers for each type of financial data. Database vendor charges may be billed directly to FactSet or its clients. Data charges to FactSet are on a fixed or royalty (per client) fee basis, with contracts generally renewable annually and cancelable on one year's notice. Many of the database information providers compete with one another and in some cases, with the Company. The Company is a significant distributor for many of the databases offered by FactSet to its clients. FactSet's advanced proprietary communication and software tools enable users to access the Company's mainframe centers and its integrated data library in order to create investment analyses using easy-to-use Windows-based programs. Wide area network connections provide a direct, high-speed data transmission link between the Company's mainframes and the client's network. Through the Company's proprietary software tools, clients can download, screen, manipulate, and analyze data in a virtually infinite array of formats, allowing for custom reports and charts designed by and for the user. By charging annual flat fees, the Company encourages its clients to make full use of the FactSet system. Other than the data charges described above, there are no extra usage charges or telecommunication costs and FactSet includes extensive support and training at no additional charges. An integral part of FactSet's service is its superior consulting and training services. The Company's client support consultants create lasting and profitable client relationships by providing hands-on training and continuous technical support to clients. Clients gain a stronger understanding of FactSet's system by working with client support consultants in developing custom applications and spreadsheets that meet their information needs. Due to the vast array of financial data that financial service professionals depend on, the Company believes that it has become increasingly important for financial service firms to integrate different types of financial information from multiple databases in order to reach their investment decisions. Financial information databases are maintained by a large number of vendors who provide the information to clients through the Internet, online dial-up connections, CD-ROM, and print formats. Without being able to integrate financial data from many different sources, individual users must access and retrieve data from different sources, often in varied formats, and manually integrate the data to complete their objective. The financial information services industry is competitive and characterized by rapid technological change containing both large and well-capitalized companies as well as smaller competitors. In a broad sense, the Company competes or may compete directly and indirectly in the United States and internationally with well-established news and information providers, market data suppliers, and with many of the database providers from whom FactSet obtains data for inclusion in the FactSet system. FactSet's most direct competitors include online and CD-ROM database suppliers and integrators such as OneSource Inc., COMPUSTAT PC Plus, Baseline Inc., StockVal Incorporated, Disclosure Inc., and IDD Information Services primarily in the United States, and Datastream and Randall-Helms primarily in international markets. A large number of these competitors offer services that, in one form or another, are similar to those offered by the Company, which in some cases are at lower prices. Although many of FactSet's competitors offer similar applications, the Company believes that none of its competitors offer a package of services as comprehensive and powerful as those offered by FactSet. -3-

The most important new feature on the FactSet system developed during fiscal 1998 was the new FactSet interface called Directions. Directions incorporates the breadth and power of the FactSet system with several enhancements and a more intuitive, easy-to-use interface. The new interface represents a complete reorganization of the user's road map so that a line of inquiry can now be pursued intuitively and easily. Directions is a major advance by the Company toward an easier-to-use system which is expected to help broaden the Company's potential user base. The Company's new interface has completed the beta test phase and is expected to be released in fiscal 1999. The number of employees of FactSet and its subsidiaries totaled 265 as of August 31, 1998, up from 193 at August 31, 1997.

To Our Shareowners We are pleased to submit FactSet's annual report for the fiscal year ended August 31, 1998. By all measures, it was a very good year. Beyond our attainment of record-breaking financial results, the period was marked by substantial progress in company building. Great strides were made in engineering, professional staffing, product development, and expansion of our physical plant. Every one of our operating units participated. We are consequently today better equipped than ever before to face the challenges and capitalize on the opportunities that lie ahead. Fiscal 1998's revenues and profits continued to surge. Revenues rose 35.2% to a new high of $78.9 million. Operating profit margins maintained an upward slope, rising another 100 basis points to 26.5%. Operating profits jumped 40.5% to $20.9 million. Net income, aided by a small gain on disposition of an investment, increased 43.9% to $12.9 million. Earnings per share, including the $0.02 of nonrecurring income, were up 42.7% to $1.17 from $0.82 in fiscal 1997. In view of the current turmoil and uncertainties occurring in global financial markets, we felt obliged to offer our shareowners a better understanding of the metrics behind FactSet's growth and stability. The table below, "Anatomy of Growth," sketches out a simple formula of the factors underlying recent growth. Anatomy of Growth 2-Year Years ended August 31, 1996 1997 1998 %Change ...................................................................................... Number of clients 439 498 564 28.5 Average users per client 14.2 21.6 29.5 107.7 Total number of users 6,245 10,771 16,647 166.6 ...................................................................................... Avg. $ commitment per client $ 116,000 $ 138,000 $ 164,000 41.4 Year-end commitments $ 50,815,000 $ 68,551,000 $ 92,479,000 82.0 ...................................................................................... As you can see, we managed to create growth at every stage. In the past two years the number of clients rose 28.5%. This is where our client retention rate, which once again exceeded 95%, played a deciding role. With the average number of passwords per account more than doubling in just two years, the total number of passwords has skyrocketed from 6,000 to nearly 17,000, for a gain of 166.6%. The number of passwords accessing our computer centers can be viewed as an indicator of the level of services we are currently delivering and reflects the rising demand for our services. More new databases and more new applications obviously translate to a broader potential audience. A recent example of this was the creation of Portfolio Management Workstation, which opened an entirely new market for FactSet and which has generated hundreds of new users. In addition, recent years have been witness to a sea change in the breadth of our business. A fair number of client additions in the last few years have been global in scope, entailing vast numbers of new users. This process is continuing. Another factor is a movement toward greater consolidation and control of -3-

data flowing into client offices. Consequently, as a supplier of more than 100 integrated databases, FactSet is evolving into a primary conduit for much of this data. Our continual addition of databases (18 in the past year alone) facilitates the process. We should also like our shareowners to gain a clearer understanding of the relationship between client "commitments" and subsequent revenue growth. "Commitments" simply means the forward billing rate. It is a freeze frame of total billings for all the services being delivered to clients at any point in time. This statistic increases essentially every month (it declined only once in the past 96 months and that was several years ago). In the table below, "Client Commitments and Reported Revenues," we display commitments at two time periods, namely at the beginning of the fiscal year and then six months later. Juxtaposed against the latter number are the actual revenues reported for that fiscal year. At least for the past few years, February commitments proved to be very reliable forecasters of full-year revenues. Client Commitments and Reported Revenues Years Ended August 31, 1996 1997 1998 1999 ........................................................................ Commitments: Beginning of year $40,223 $50,815 $68,551 $92,479 Ensuing February 44,099 58,357 78,652 Full-year revenues 44,348 58,358 78,911 ........................................................................ [Picture of Howard E. Wille, Chairman and Chief Executive Officer, and Charles J. Snyder, President and Chief Technology Officer] We of course, do not know what the near-term future holds, particularly in view of recent world events. We do, however, know that we start the new fiscal year comfortably ahead of fiscal 1998. We begin with client commitments of $92.5 million, which is 34.9% above the $68.6 million of a year ago. We cannot predict what client commitments will be next February or, for that matter, whether that month's level will again produce a good forecast of fiscal 1999 revenues; we will deal with these short-term considerations as they unfold. But we remain confident in the efficacy of our business model and the soundness of the long-term strategies we are pursuing. Reference to long-term strategies gives rise to one of our pet peeves; namely, the market's focus on quarterly performance. We believe that it is our fundamental obligation to serve the best long-term interests of shareowners. We are thus troubled by the near obsession many people have with quarterly financial results. How can you sustain a long-term plan while managing the -4-

business to meet someone else's short-term "expectations"? The foregoing comments notwithstanding, we have produced ten quarterly reports since becoming a public company in June 1996. The first was the May 1996 report in which revenues showed a gain of 26.1%. That gain was smaller than any of the nine subsequent quarters. In fact, in each of the last seven quarters revenue growth has exceeded 32%. And for these same seven quarters, the smallest rise in earnings per share was just under 36%. In our most recent three-month report (August 1998), E.P.S. were up 43.5% on revenue growth of 34.7%. While we do not manage for quarterly results, the underlying strength of our secular growth and the consistency of profit margins have helped generate strong interim results. Quarterly Performance Year-to-Year % Change Operating Revenues E.P.S. Profit Margin .............................................................. 1996: May 26.1% 45.5% 24.6% August 28.3 33.3 24.3 November 26.5 28.6 26.0 .............................................................. 1997: February 32.4 35.7 25.0 May 32.0 37.5 25.8 August 34.7 43.8 25.0 November 36.4 38.9 26.3 .............................................................. 1998: February 36.3 42.1 25.5 May 33.8 36.4 26.8 August 34.7 43.5 27.1 .............................................................. Our high profit margins have devolved from a combination of factors, prominent among which is our record of client retention. We have successfully kept client retention above 95% ever since we started measuring this factor. Maintenance of client loyalty is reliant on service integrity, on superior technology, and on basic business fairness. High profitability is also a function of corporate style. We try hard to control costs, to avoid overstaffing, and to run a generally tight ship. We do not stint on making investments in new technology and on building pleasant work environments. We strive to attract talented personnel willing to work hard for good recompense. Average revenues per employee have held at $345,000 for each of the past two years in the face of heavy investment in infrastructure. Employees contributing to the Company's success are afforded wealth-building opportunities through stakes in stock ownership. This philosophy has served the Company well in the past and should continue to do so. With profit margins at their current levels, we cannot realistically anticipate significant additional improvements. The only sustainable source of earnings growth is expanding revenues. We have generated most of our growth by adding clients, passwords, and -5-

applications, with a resultant increase in revenues per client. The majority of growth has been developed from within our existing client base. We intend that this process be maintained. Longer-term we will need to create new markets for our services both within markets we already serve and new ones that can be exploited through application of FactSet's demonstrably superior computer and database technologies. An example of new market niches within our existing client base is our Portfolio Management Workstation, or PMW. This application allows a client to examine a portfolio's fundamental structure and to identify the sources of investment returns. It produces this analysis in both absolute and benchmark relative terms. In addition, PMW's integration with FactSet's other suite of services provides advance information for decision support. Introduced late in fiscal 1997, this service is giving strong evidence of protracted growth opportunities for FactSet. We have two dedicated teams of product designers and applications engineers addressing the development needs of this innovative service. Judging from the speed of client acceptance, we appear to have identified a void in the services available to the investment management community. The most important 1998 contribution of our product development group was completion of FactSet's new "front end." We named it DIRECTIONS as a code word for easy passage from one FactSet application to another. It represents a complete reorganization of the user's road map so that a line of inquiry can now be pursued intuitively and easily. If a client, for example, has an interest in a specific company, all the data we have on that company is now organized to be a mouse click away from all of our other data sources. Thus, a user might want to see a brief company overview or an in-depth look at that company's financials, its EDGAR* filings, a business description, recent news, a security price record, or an earnings estimate. They are all immediately at hand. DIRECTIONS is ready for deployment, having already passed the beta test phase. Installation will entail considerable effort and time. Our systems engineering and consulting staffs are geared up to accomplish the task. It is our expectation that this major advance toward ease-of-use will help broaden our potential user base. Year 2000 FactSet is now prepared to manage the millennium date change systemwide. Our compliance with a four-digit year format will not affect clients using our system. The behavior of no existing request codes, screening items, or FactSet formulas will be altered. Futhermore, wherever a date can be entered, whether in an online application or within a data request code, either two- or four-digit years will be correctly interpreted. As of June 30, 1998, we completed our "Year 2000" transition related to our mainframe systems and applications interface. This means that any enhancements or modifications to the behavior of the online system resulting from our compliance effort are now complete and available to users. Having achieved this a full 18 months prior to the turn of the millennium has given FactSet's users ample time for their remediation efforts. It also insures that the code, which will be in place in the year 2000, will be thoroughly tested and stable. * EDGAR is a registered trademark of the U.S. Securities and Exchange Commission. -6-

Euro Currency Conversion Eleven countries from the 15-member European Union are scheduled to transition to the new currency, the euro, on January 1, 1999. Due to the extensive number of global databases offered through FactSet, the shift to the new currency will have a broad impact. On December 31, 1998, the conversion rate between each of these 11 currencies and the euro will be irrevocably fixed. Going forward from that date, converting from one participating country's currency to any other currency will be a simple calculation with the fixed rate and the floating euro rate. How to view pre-euro data requires some debate. To provide the most flexible solution, we will by default convert all legacy currency data to the euro via the fixed rates. Therefore, after the conversion, all data in any of the 11 former national currencies will be displayed in euros unless otherwise specified. To summarize where we stand, 1998 was a great year. Record-breaking financial performances were topped off with major strides in staffing, product development, technological achievement, and facilities expansion. While there might be a few bumps in the road ahead due to unsettled world conditions, we start this next leg of the journey well ahead of year-earlier levels, which should translate to another good year. And beyond short-term considerations, FactSet has never been in stronger shape. We have the strategies, the technology, and the professional personnel to advance resolutely into the new millennium.

With explosive growth in the number of FactSet users, the past year required extraordinary growth in systems resources. [Picture] The system architecture at FactSet is unique in the industry. Both applications and databases are developed and executed from the Alpha platform and are accessed via FactSet's communications program installed on client workstations. As a consequence of this architecture, updates and enhancements to the system are reflected instantaneously across our entire client base, and in fact, are a daily occurrence. The result is a system that is highly responsive to the ever-evolving and -expanding needs of FactSet clients. [Picture] Data center systems, wide area networking, Lotus Notes, desktop PC systems and support, as well as telephony systems were all successfully scaled to meet the additional demand. Our data centers in Greenwich and New York were each upgraded to five clustered COMPAQ-Digital 8480 AlphaServers, each with 10 gigabytes of RAM and 1.6 terabytes of disk space. This produced an 80% increase in CPU power, a 108% increase in memory, and a 60% expansion in disk space. [Picture] -8-

[Picture] DIRECTIONS required several enhancements to our graphical user interface toolkit. Among these were the ability to generate presentation-quality output directly from our online applications as well as a complete overhaul of our charting system to allow for interactivity and a broader variety of chart styles. We also added the ability to encrypt our communications stream, allowing us to offer clients more security options when using our system to manipulate their own sensitive data. The Portfolio Management Workstation in particular will benefit enormously from these enhanced security features. [Picture] The most important engineering effort in the past year was DIRECTIONS, our completely redesigned user interface. Another intriguing application release was Company Web Site, which provides clients with a seamless window into the Internet. We created a database of Web site addresses for all major companies worldwide. With this database, FactSet DIRECTIONS becomes a Web browser leading the user to the Web site of a company for more detailed information-normally its annual report. [Picture] -9-

MANAGEMENT'S DISCUSSION AND ANALYSIS Revenues Revenues for fiscal 1998 increased 35.2% to a record $78.9 million. Fiscal 1997 revenues rose 31.6% to $58.4 million versus $44.3 million in the prior fiscal year. Increased service subscriptions and users, client additions, and continued rapid expansion of international operations drove this growth. Further penetration of existing clients accounted for approximately two-thirds of the revenue growth in fiscal 1998 and 1997. Passwords. Passwords, a measure of the number of users, grew more than 50% during fiscal 1998, totaling more than 16,000 at August 31, 1998. Fiscal 1997 saw client passwords increase over 70%. Client Count. The number of clients serviced by FactSet expanded to 564 as of August 31, 1998. Fiscal 1998 marked the first year in which market penetration exceeded 50% among the top 300 U.S. investment managers. The Company also counted among its clients all top ten U.S. investment banks. The net increase of 66 clients over the past 12 months was slightly more than the 59 net client additions in fiscal 1997. International. The Company's overseas revenues rose nearly 60% in fiscal 1998 to $10.0 million. In fiscal 1997, international revenues were $6.3 million, more than double the prior year. The continuing revenue growth over the past two fiscal years reflects the strong demand for the Company's broadening array of services and data available to its international clients. Revenues from international sources accounted for nearly 13% of consolidated revenues for the 12 months of fiscal 1998, up from 11% for the comparable period a year earlier. Commitments. Client commitments at August 31, 1998 rose 34.9% to $92.5 million. At fiscal year end 1997, commitments improved 35.0% over the prior year to $68.6 million. ("Commitments" at a given point in time represent the forward-looking revenues for the next 12 months from all services currently being supplied to clients.) During the past three fiscal years, commitments grew in every month. These increases translated into an average commitment per client of $164,000 and $138,000 at the end of fiscal 1998 and 1997, respectively. As a matter of policy, the Company does not seek to enter into written contracts with its clients. Clients are free to add to, delete from, or terminate the service at any time. Historically, revenues at the end of the fiscal year have been higher than total commitments reported at the beginning of the fiscal year. Client Concentration. As of and for the fiscal year ended August 31, 1998, no individual client accounted for more than 4% of total commitments or total revenues. The ten largest clients did not account for as much as 15% of either revenues or commitments. Client Retention. Client retention in fiscal 1998 continued, as it has for the past nine years, at a rate in excess of 95%.

Operating Expenses % of Revenues Years Ended August 31, 1998 1997 1996 ................................................................................ Cost of services 38.8% 40.0% 40.6% Selling, general, and administrative 30.9 30.9 32.1 Other expenses 3.9 3.6 3.2 Income taxes 12.5 11.7 11.1 Retained earnings 13.9 13.8 13.0 ----- ----- ----- 100.0% 100.0% 100.0% ===== ===== ===== ................................................................................ Cost of Services. Cost of services represented 38.8% of total revenues in fiscal 1998, a decline of 1.2% from the prior fiscal year. As a result of the growth of the Company's business, cost of services in fiscal 1998 increased 31.1% to $30.6 million versus a 29.6% rise in fiscal 1997. These increases were due mainly to higher compensation and benefit expenses of employees in the applications engineering and consulting groups and increased depreciation expense. Employee compensation and benefits for the aforementioned groups increased $3.5 million in fiscal 1998 and $2.4 million in fiscal 1997. Employee additions and merit raises drove these increases. To meet the growing programming and support requirements of the Company, the applications engineering and consulting departments increased staff by 42% during fiscal 1998. In fiscal 1997, these departments grew by 41%. Depreciation expense on computers increased by $1.5 million in both fiscal 1998 and 1997. Such increases were the result of higher levels of computer equipment capital spending to upgrade and increase mainframe capacity in support of an expanded user base. Fiscal 1998's and 1997's computer-related equipment purchases exceeded the prior year's by $5.0 million and $200,000, respectively. Selling, General, and Administrative. Selling, general, and administrative expenses ("SG&A") was 30.9% of total fiscal 1998 and 1997 revenues. For fiscal 1998, SG&A grew by 35.0% to $24.4 million. In fiscal 1997, SG&A rose 26.6% to $18.0 million. These increases were attributable to higher employee compensation in the sales, product development, and various other support departments; increased promotional expenses; and the expansion of office facilities. During fiscal 1998, employee compensation and benefits increased $4.1 million over the prior year. In fiscal 1997, employee compensation and benefits grew by $1.8 million. During fiscal year 1998, the sales, product development, and various other support departments increased staff by 30%. At fiscal year end 1997, headcount grew by 23% from the year before. Promotional expenses rose $1.1 million during the 12 months of fiscal 1998. Higher travel costs to support a larger, more diverse client base drove the increase. In fiscal 1997, office space additions caused occupancy expenses to increase by $850,000. Foreign Currency. The majority of international clients pay for services in U.S. dollars and the net monetary assets held by the Company's foreign offices are insignificant. More than 95% of fiscal 1998 revenues were billed in U.S. dollars. Accordingly, the Company's exposure to foreign currency fluctuations is immaterial. -14-

Operating Margins Operating margins rose 100 basis points, from 25.5% in fiscal 1997 to 26.5% for fiscal 1998. Fiscal 1997 operating margins increased 150 basis points from fiscal 1996. Margin improvement was the result of declining clearing fees, data costs, and rent as a percentage of sales partially offset by increased compensation costs and depreciation expenses. Clearing Fees. Cash fees generate higher margins than commission revenues, although net revenues to the Company are approximately the same under both payment methods. Clients electing to settle obligations using commissions on securities transactions pay a higher amount than cash-paying clients in order to cover clearing charges paid by the Company. Over the past three fiscal years, commissions as a percentage of total revenues have been declining. Cash fees represented 57% of total revenues in fiscal 1998, 53% in fiscal 1997, and 47% in fiscal 1996. Data Costs. During fiscal 1998, data costs declined as a percentage of revenues due to a combination of strong top-line growth and certain database charges formerly paid through FactSet moving to direct billing by the database supplier. This changeover had the effect of raising FactSet's operating margins. Rent. Improved utilization of office space in fiscal 1998 increased operating margins. Depreciation. Operating margin improvement in fiscal 1997 was also partially offset by added depreciation on computer equipment. Profitability Net Income. Fiscal 1998 net income increased 43.9% to $12.9 million. Included in net income was a $242,000 extraordinary gain from the sale of an investment in a limited partnership. Excluding this sale, net income was $12.6 million for the 12 months of fiscal 1998, an increase of 41.2% over the prior year period. Fiscal 1997 net income rose 38.0% to $8.9 million compared to fiscal 1996. Earnings Per Share. Diluted earnings per share were $1.17 for fiscal 1998. Excluding the extraordinary gain, diluted earnings per share were $1.15, up 40.2% from the year earlier. For fiscal 1997, diluted earnings per share were $0.82 compared to $0.60 for fiscal 1997. Liquidity Cash from Operations. Cash generated by operating activities was $21.2 million for the 12 months of fiscal 1998 compared to $17.0 million in the same period a year ago. This increase primarily reflected higher levels of profitability as well as additional depreciation and amortization expenses. Capital Expenditures. Cash used in investing activities was $10.6 million in fiscal 1998 with capital expenditures of $12.0 million partially offset by the sale of a $1.4 million limited partnership investment. Major capital expenditures included the purchase of two COMPAQ-Digital 8480 AlphaServer systems for each data center, more than doubling RAM to 100 gigabytes and increasing both I/O capacity and disk storage capacity by approximately 60%.

Financing Operations and Capital Needs. Capital and operating expense requirements have been financed, in their entirety, by cash from operations. FactSet has no outstanding debt. Cash and cash equivalents at August 31, 1998 totaled $37.6 million, which represented 53% of the Company's total assets. The Company is in the process of negotiating revolving credit facilities totaling $25 million for working capital and general corporate purposes, including certain acquisitions. There are no present plans to utilize any portion of the available credit facilities upon signing of the agreements. Forward-Looking Factors Recent Market Trends. Until the fourth quarter of fiscal 1998, the strength of the U.S. and European financial markets over the past three fiscal years supported a robust business environment for both investment management and investment banking firms. In Asia, the equity markets have been more volatile, particularly during the 1998 fiscal year, with the Nikkei index recently hitting a 13-year low. Despite these difficult conditions, revenues from the Company's Pacific Rim operations grew 32% in fiscal 1998 from the prior fiscal year. The Company has a very small share of a market in which companies spend annually more than $10 billion on financial information. While the buoyant global economies and increased activity in the U.S. and international stock markets have positively impacted FactSet, the Company believes that there is only a moderate correlation between performance of the financial markets and its results of operations. A continuing downward trend in the global stock markets would likely impact the profitability of some FactSet clients adversely. With that, the possibility of personnel reductions among clients increases, as does the likelihood that more clients would reduce or cancel services. Therefore, a protracted bear market could interrupt Company revenue growth and could adversely impact future results of operations. Capital Spending. The Company, in its continuing effort to expand in the global marketplace, has made significant investments in its infrastructure, particularly in technology and people. Capital spending in fiscal 1998 ($12 million) was approximately twice that of fiscal 1997 and is likely to exceed $15 million in fiscal 1999. Investments in People. Expansion of the Company's workforce and strong employee retention continues. Fiscal 1998's annual employee retention rate exceeded 92%. At August 31, 1998, the Company employed 265 individuals, an increase of 37% from the end of fiscal 1997. Office Facility Expansion. In order to accommodate the growth of its business, the Company signed leases during the fiscal year for new office space in New York, Stamford (Connecticut), San Mateo (California), Hong Kong, and Tokyo. During fiscal 1999, incremental SG&A from additional occupancy costs is not expected to be material. Year 2000. Almost all companies are confronted with business risks associated with the Year 2000 because many computer hardware and software systems use only two digits to indicate a year. These systems and programs, therefore, may incorrectly process dates beyond 1999, which may result in information errors or system failures. -16-

The Year 2000 issue extends beyond the Company's internal back-office systems to its mainframe centers and related application programs that support the entire client base. Given the relative importance of this issue, the Company recognizes the need to remain vigilant and is vigorously pursuing its analysis, assessment, and planning for the Year 2000. The Company has completed testing of its mainframe systems and application interface and believes no further Year 2000 alterations to these systems are necessary. The assessment of Year 2000 readiness of data from third-party suppliers and data storage capabilities is in progress. The Company maintains ongoing discussions with its data suppliers and has been encouraging them to prepare and transmit data that is Year 2000 compliant. The extent of preparation and readiness varies among suppliers. Contingency plans have been arranged with a view that the Company will not rely on the ability of data suppliers to provide Year 2000 compliant data. Programs have been tested and are planned to adjust data to be Year 2000 compliant if a data supplier does not provide it in the proper format. The suppliers of significant internal back-office systems (accounting and payroll) have been queried for confirmation that their software is Year 2000 ready. The Company has received written confirmations from these suppliers and to date there has been no indication that these suppliers will not be Year 2000 compliant. The Company also faces Year 2000 issues with third-party telecommunications systems over which its products and services are accessed by clients. The Company has reviewed correspondence from each of its significant telecommunications providers concerning Year 2000 compliance. There has been no indication from such review that Year 2000 issues are anticipated to cause a significant failure or interruption of telecommunications services. However, a significant service interruption on the telecommunications networks over which the Company conducts its business may result in a material adverse effect on the Company's financial condition, results of operations, and cash flows. Past and estimated costs to prepare all FactSet systems to be Year 2000 compliant have not been and are not expected to be material. Year 2000 changes take place at the Company's mainframe centers and do not require a separate program installation on each user's personal computer or supporting network. Year 2000 compliance matters have not delayed and are not expected to delay any significant information technology projects. There can be no assurances that the databases distributed by the Company, or related applications, mainframe, telecommunications, and back-office systems, do not contain undetected errors or defects associated with the Year 2000 date functions. Although the Company believes its efforts will be successful and does not anticipate the cost of compliance to be material, any failure or delay to address Year 2000 issues could result in major disruption of its business, damage to the Company's reputation, and a material, adverse change in its results of operations. The Euro. Effective January 1, 1999, 11 of the 15 member countries of the European Union will shift to a new single currency, the euro. The exchange rates for the participating currencies will be irreversibly fixed against the euro. The impact on the Company's results of operations from the euro conversion are not expected to be material. There are no competitive implications to the Company from increased price transparency, as all -17-

European clients are billed in U.S. dollars. In addition, the euro is expected to have minimal impact on the Company's products and services. Income Taxes. At August 31, 1998, employees held vested stock options to purchase 982,000 shares of the Company's common stock. The majority represents incentive stock options with an exercise price of $2.70. The exercise of nonqualified stock options or disqualifying disposition of incentive stock options has a positive impact on the Company's effective tax rate. The extent and timing of such exercises are beyond the control of the Company. However, it is likely that the Company's future effective tax rate will decrease as a result of option exercises. The Company's tax filings are subject to audit by federal and state tax authorities in the normal course of business. While the Company does not anticipate that any such audits currently in process will result in tax assessments that would have a material adverse effect on the results of operations or financial position of the Company, there is inherent uncertainty in this process. Accounting Pronouncements. In June 1997, Statement of Financial Accounting Standards ("SFAS") No. 130, Reporting Comprehensive Income, and SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, were issued. Neither statement will have any effect on the Company's financial position or results of operations, as they require only changes in or additions to current disclosures. In March 1998, Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use, was issued and is effective for the Company's fiscal year 2000. The potential impact on the Company's results from adopting this statement is under review. Refer to Note 2, "Accounting Policies" for further information on new accounting pronouncements. Forward-Looking Statements. This Management's Discussion and Analysis contains forward-looking statements that are based on management's current expectations and beliefs. The phrases "commitments," "believes," "would likely," "could," "is likely," "continues," "will not," "is expected," "may," "are planned," "is not expected," "may result," "are not expected," "does not anticipate," "could result," "remains uncertain," "are uncertain," and "will have," are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties, and assumptions which are difficult to predict ("future factors"). Therefore, actual results may differ materially from what is expressed or forecasted in such forward-looking statements. The Company undertakes no obligation to publicly update any forward-looking statements as a result of new information, future events, or otherwise. Future factors include the ability to hire qualified personnel; maintenance of the Company's leading technological position; the impact of global market trends on the Company's revenue growth rate and future results of operations; the success of the Year 2000 and euro compliance activities; the negotiation of contract terms supporting new and existing databases; the successful resolution of ongoing audits by tax authorities; the continued employment of key personnel; the absence of U.S. or foreign governmental regulation restricting international business; and the sustainability of historical levels of profitability and growth rates in cash flow generation. -18-

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FactSet Research Systems Inc. August 31, 1998, 1997, and 1996 1. ORGANIZATION AND NATURE OF BUSINESS FactSet Research Systems Inc. (the "Company") provides online integrated database services to the financial community. The Company's revenues are derived from subscription charges. Solely at the option of each client, these charges may be paid either in commissions on securities transactions (in which case subscription revenues are recorded as commissions) or on a cash basis (in which case subscription revenues are recorded as cash fees). To facilitate the receipt of subscription revenues on a commission basis, the Company's wholly owned subsidiary, FactSet Data Systems, Inc. ("FDS"), is a member of the National Association of Securities Dealers, Inc. and is a registered broker-dealer under Section 15 of the Securities Exchange Act of 1934. FDS's only function is to facilitate the receipt of commission payments with respect to subscription charges and it does not otherwise engage in the securities business. Subscription revenues paid in commissions are derived from securities transactions introduced and cleared on a fully disclosed basis primarily through two clearing brokers. That is, a client paying subscription charges on a commission basis directs the clearing broker, at the time the client executes a securities transaction, to credit the commission on the transaction to FDS's account. FactSet Limited and FactSet Pacific, Inc. are wholly owned subsidiaries of the Company and are U.S. corporations with foreign branch operations in London, Tokyo, and Hong Kong. 2. ACCOUNTING POLICIES The significant accounting policies of the Company and its subsidiaries are summarized below. Financial Statement Presentation. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany activity and balances have been eliminated from the consolidated financial statements. Cost of services is composed of employee compensation and benefits for the applications engineering and consulting groups, clearing fees, data costs, computer maintenance and depreciation expenses, and communication costs. Selling, general, and administrative expenses include employee compensation and benefits for the sales, product development, and various other support departments, promotional expenses, rent, amortization of leasehold improvements, depreciation of furniture and fixtures, and office expenses. The components of other expenses are professional fees and miscellaneous expenses. Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. -26-

Revenue Recognition. Subscription charges are quoted to clients on an annual basis, but are earned monthly as services are provided. Subscription revenues recorded as commissions and subscription revenues recorded as cash fees are each recorded as earned each month, based on one-twelfth of the annual subscription charge quoted to each client. Amounts that have been earned but not yet paid through the receipt of commissions on securities transactions or through cash payments are reflected on the Consolidated Statements of Financial Condition as receivables from clients. Amounts that have been received through commissions on securities transactions or through cash payments that are in excess of earned subscription revenues are reflected on the Consolidated Statements of Financial Condition as deferred cash fees and commissions. Clearing Fees. When subscription charges are paid on a commission basis, the Company incurs clearing fees, which are the charges imposed by the clearing brokers used to execute and settle clients' securities transactions. Cash and Cash Equivalents. Cash and cash equivalents consists of demand deposits and money market investments. Investments. Investment securities are classified as available-for-sale securities in accordance with Statement of Financial Accounting Standards ("SFAS") No. 115, Accounting for Certain Investments in Debt and Equity Securities, and are reported at market value or fair value as determined by management. Unrealized gains and losses on available-for-sale securities are recognized as a separate component of stockholders' equity, net of tax. Property, Equipment, and Leasehold Improvements. Depreciation of computers and related equipment acquired before September 1, 1994 is recognized using the double declining balance method over estimated useful lives of five years. Computers and related equipment acquired after September 1, 1994 are depreciated on a straight-line basis over estimated useful lives of three years. Depreciation of furniture and fixtures is recognized using the double declining balance method over estimated useful lives of five years. Leasehold improvements are amortized on a straight-line basis over the terms of the related leases or estimated useful lives of the improvements, whichever period is shorter. Deferred Taxes. Deferred taxes are determined by calculating the future tax consequences associated with differences between financial accounting and tax bases of assets and liabilities. A valuation allowance is established to the extent management considers it more likely than not that some portion or all of the deferred tax assets will not be realized. The effect on deferred taxes from income tax law changes is recognized immediately upon enactment. The deferred tax provision is derived from changes in deferred taxes on the balance sheet and reflected on the Consolidated Statements of Income as a component of income taxes. The Company records deferred taxes for such items as accrued compensation, deferred cash fees and commissions; deferred rent; and property, equipment, and leasehold improvements. -27-

Earnings Per Share. The computation of basic earnings per share in each year is based on the weighted average number of common shares outstanding. The weighted average number of shares outstanding includes shares issued to the Company's employee stock ownership plan at the date authorized by the Board of Directors. Diluted earnings per share is based on the weighted average number of common shares and common share equivalents outstanding. Shares available pursuant to grants made under the Company's stock option plans are included as common share equivalents using the treasury stock method. Stock-Based Compensation. The Company follows the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation. See Note 13, "Stock Option Plans," for further information. New Accounting Pronouncements. In June 1997, SFAS No. 130, Reporting Comprehensive Income, and SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, were issued. Both statements will have no effect on the Company's financial position or results of operations, as they require only changes in or additions to current disclosures. SFAS No. 131 was adopted in fiscal 1998. See Note 14, "Segments" for further information. SFAS No. 130 will be adopted in fiscal 1999. In March 1998, Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use, was issued and is effective for the Company's fiscal year commencing in the year 2000. The potential impact from adopting this statement on the Company's results is under evaluation. 3. SUBSCRIPTION REVENUES Each client has the option to pay subscription charges either in the form of commissions on securities transactions or on a cash basis, regardless of the nature or amount of the services provided by FactSet to such client. When a client elects to pay subscription charges in the form of commissions, the Company incurs clearing fees, which are charges imposed by the clearing broker used to execute and settle clients' securities transactions. For commission transactions, the dollar amount payable to the Company is higher than the fee that would be payable for the same services on a cash basis because of the associated clearing fees incurred by the Company. However, commissions net of related clearing fees are approximately equal to the fees that would be paid by a client on a cash basis. -28-

NET CAPITAL As a registered broker-dealer, FDS is subject to Rule 15c3-1 under the Securities Exchange Act of 1934, which requires that FDS maintain minimum net capital equal to the greater of $5,000 or 6.67% of aggregate indebtedness and a ratio of aggregate indebtedness to net capital of not more than 15 to 1 (the "minimum net capital requirement"). FDS may be prohibited from paying cash dividends to the Company if such dividends would result in its net capital falling below the minimum net capital requirement or its ratio of aggregate indebtedness to net capital exceeding 15 to 1. At all times during the years presented, FDS had net capital in excess of its minimum net capital requirement. At August 31, 1998, FDS had net capital of $3,854,417, which was $3,584,675 in excess of its minimum net capital requirement of $269,742. The ratio of aggregate indebtedness to net capital was 1.05 to 1. 11. LEASE COMMITMENTS The Company leases office space in Greenwich, Connecticut under a lease agreement which expires in August 2003 and which contains certain escalation clauses. The Company is required to pay minimum annual rental fees averaging $1,376,617 through the end of the lease. The total minimum rental payments associated with the lease are being recorded as rent (a component of selling, general, and administrative expenses) on a straight-line basis over the period commencing with the occupancy of the premises in August 1990 through the end of the lease. In fiscal 1998, the Company entered into new lease agreements in connection with opening offices in New York, Hong Kong, and Stamford (Connecticut), as well as expanding office space in Tokyo and San Mateo (California). The new leases expire at various dates through the period ending November 2008, have a weighted average term of 8.2 years, and require a minimum annual aggregate rental payment of $1,235,888. -32-

At August 31, 1998, the Company's lease commitments for office space, with noncancelable lease terms in excess of one year, provide for the following minimum annual rentals: Years Ended August 31, ................................................................................ 1999 $2,906,551 2000 2,805,723 2001 3,086,386 2002 2,948,575 2003 2,919,862 Thereafter 2,704,991 --------- Minimum lease payments $17,372,088 ========== ................................................................................ At August 31, 1998, standby letters of credit aggregating approximately $279,417 have been issued on behalf of the Company serving as security deposits for leased premises. 12. EMPLOYEE STOCK OWNERSHIP PLAN The Company sponsors an Employee Stock Ownership Plan (the "Plan" or "ESOP"). The Company may make optional annual contributions for the benefit of participating employees in such amounts as designated by the Board of Directors. The Board of Directors authorized contributions in the amounts of $750,000, $600,000, and $500,000 for the years ended August 31, 1998, 1997, and 1996, respectively. Such contributions are recorded in cost of services and selling, general, and administrative as compensation expense at the time they are authorized; issuance of the related shares occurs shortly thereafter, generally in the following fiscal year. Employees of the Company and its subsidiaries who have performed at least 1,000 hours of service during the year are generally eligible to participate in the Plan. The Company contribution allocated to an individual account begins to vest upon completion of the employee's third year of service at the rate of 20% in each successive year of service. Forfeited non-vested interests in the Plan are allocated to the other participants' accounts. The Plan owned 828,834, 806,966, and 787,824 shares of the Company's common stock at August 31, 1998, 1997, and 1996, respectively. 13. STOCK OPTION PLANS The Company's 1994 Stock Option Plan (the "1994 Plan") was adopted by the Board of Directors on December 21, 1994, and approved by the Company's stockholders on December 22, 1994. Under the 1994 Plan, stock options were made available to purchase up to 1,481,000 shares of common stock. In fiscal year 1995, incentive and non-qualified stock options to purchase up to 1,481,000 shares of common stock at prices which range from $2.50 to $2.70 per share were granted to employees of the Company. -33-

The Company's 1996 Stock Option Plan (the "1996 Plan") was adopted by the Board of Directors on April 29, 1996, and approved by the Company's stockholders on May 1, 1996. Under the 1996 Plan, stock options were made available to purchase up to 950,000 shares of common stock. In fiscal years 1998, 1997, and 1996, incentive and non-qualified stock options to purchase up to 317,000, 211,000, and 40,000 shares of common stock, respectively, at prices which range from $17.00 to $30.00 per share were granted to employees of the Company. The Company's Non-Employee Director Stock Option Plan was adopted by the Board of Directors and ratified by the Company's stockholders in fiscal 1998. Non-qualified options to purchase 40,000 of common stock at $28.19 were granted to non-employee directors of the Company. Options granted under the 1994 Plan, the 1996 Plan, and the Non-Employee Director Plan (the "Plans") expire not more than ten years from the date of grant and, in most cases, vest at a rate of 20% per year beginning one year after the grant date. The option exercise prices equal the fair market value of the Company's stock on the date the option was granted. Options are not transferable or assignable other than by will or the laws of descent and distribution. During the grantee's lifetime, they may be exercised only by the grantee. A summary of the status of the Company's stock option plans at August 31, 1998, 1997, and 1996, and changes during each of the years then ended is presented below: 1998 1997 1996 Wtd. Avg. Wtd. Avg.

In fiscal 1997, the Company adopted SFAS No. 123, Accounting for Stock-Based Compensation. As permitted by SFAS No. 123, the Company accounts for the Plans under APB Opinion No. 25, under which no compensation cost has been recorded. Had compensation cost for the 1996 Plan been determined pursuant to the measurement principles under SFAS No. 123, the Company's net income and earnings per share would have been reduced to the following pro forma amounts for fiscal years 1998 and 1997: Years Ended August 31, 1998 1998 1997 1997 Thousands, except per share data As Reported Pro Forma As Reported Pro Forma ................................................................................

Disclosure of the pro forma impact from the method of accounting prescribed by SFAS No. 123 is effective for fiscal years beginning after December 15, 1994. As such, options granted in fiscal 1995 are excluded from the calculations of compensation costs included in the pro forma net income and earnings per share amounts above. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used for grants in fiscal years 1997 and 1998: Years Ended August 31, 1998 1997 ................................................................................ Risk-free interest rate 5.51% 6.10% Expected lives of options 4.2 years 4 years Expected volatility 38% 31% Dividend yield - - ................................................................................ 14. SEGMENTS The Company has two reportable segments based on geographic operations: the United States ("U.S.") and International. Each segment markets online integrated database services to investment managers, investment banks, and other financial services professionals. The U.S. segment services financial institutions throughout North America while the International segment serves investment professionals primarily in Europe and the Pacific Rim. The International segment consists of two foreign branch operations that are primarily staffed by sales and consulting personnel. Segment revenues reflect direct sales of products and services to clients based on their geographic location. There are no intersegment or intercompany sales. Each segment records compensation, travel, office, and other direct expenses related to its employees. Expenses for software development, expenditures related to the Company's computing centers, data costs, clearing fees, -35-

income taxes, and corporate headquarters charges are recorded by the U.S. segment and are not allocated to the foreign segments. The accounting policies of the segments are the same as those described in Note 2, "Accounting Policies."

Two separate regions (Europe and the Pacific Rim) were aggregated to form the International segment. The Europe and Pacific Rim segments have similar market characteristics and each offers identical products and services through a common distribution method to financial services institutions.

Fees quoted by the Company are based on subscriptions to its products and services. Around-the-clock consulting, unlimited client training, and payment of daily communication costs are significant services provided to all clients. Fees for these services are included in subscription charges and are not separately stated in client invoices or in the Company's accounting records. Accordingly, disclosure of revenues by products and services is not practicable. For the fiscal year ended August 31, 1998, no individual client accounted for more than 4% of total revenues. Revenues from the top ten clients did not exceed 15% of the total. 15. OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF CREDIT RISK In the normal course of business, securities transactions of clients of FDS are introduced and cleared through correspondent brokers. Pursuant to agreements between FDS and its correspondent brokers, the correspondents have the right to charge FDS for unsecured losses that result from a client's failure to complete such transactions. The Company seeks to control the credit risk of nonperformance by evaluating the creditworthiness of its clients and by reviewing their trading activity on a periodic basis. Receivable from clearing brokers represents a concentration of credit risk and relates to securities transactions cleared through two correspondent brokers. -37-
