PROSPECTUS SUMMARY

The following summary is qualified in its entirety by the more detailed information, historical and pro forma financial statements and risks factors appearing elsewhere in this Prospectus and should be read only in conjunction with the entire Prospectus. Unless otherwise specified, the information in this Prospectus (a) gives effect to the contribution to Realty Information Group, Inc. (the "Company") of all of the outstanding equity interests in its predecessors, OLD RIG, Inc. ("RIGINC") and Realty Information Group, L.P. ("RIGLP"), in exchange for the Company's shares at a rate of 3.113 shares of Company Common Stock for each share of RIGINC or unit of RIGLP, (b) except as otherwise noted, does not give effect to the contribution to the Company of all of the outstanding shares of Jamison Research, Inc. ("Jamison") in consideration of Company shares (the "Jamison Acquisition"), (c) assumes an initial public offering price of $11.00 per share and (d) assumes that the Underwriters' Over-Allotment Option is not exercised. See "Transactions in Connection with the Offering." The Company and Jamison are referred to collectively as the "Combined Company."

THE COMPANY

The Company is a leading provider of comprehensive, building-specific information to the United States commercial real estate industry and related industries. The Company has created a proprietary database (the "Database" and together with Jamison's database, the "Combined Database"), through internal development and strategic acquisitions, that the Company believes is significantly more comprehensive, accurate, and up-to-date than any other database of information detailing office and industrial space in the United States. The Database includes hundreds of data fields providing substantive information as well as digitized photographs and floor plan images on individual commercial buildings in the Company's markets. The Combined Database tracks over eight billion square feet of office and industrial space in more than 150,000 buildings, better than twice the coverage of the Combined Company's nearest competitor. The Combined Database also contains detailed information on 120,000 tenants and 14,000 buildings for sale and is supported by one of the largest office and industrial real estate research staffs in the nation. In addition, the Company has developed a portfolio of multimedia software products with Internet connectivity that allows clients to access the Database and from which the Company generates revenue in each of its markets.

The Combined Company is the market leader in providing comprehensive office and industrial real estate information in nine of the ten largest United States metropolitan areas. After establishing the Database and software products in the Washington, D.C. metropolitan area, the Company expanded to Baltimore (1992), and thereafter to New York City (1994), Westchester County, Long Island and Northern New Jersey (1995), Los Angeles, Orange County and Chicago (1996), and Philadelphia, San Francisco and Boston (1997). In connection with the Offering, the Company will acquire Jamison, the leading office and industrial real estate information provider in Atlanta and Dallas/Fort Worth. The Company plans to continue its aggressive geographic expansion in the United States and in select international markets. In most instances, the leading office and industrial real estate brokerage firms in a new market have become the Company's clients within six months of entry. The Company currently generates positive cash flow from operations in each regional market in which it has operated for at least 18 months.

The Company's clients access the Database using the Company's multimedia software products. These software products include (i) CoStar, a product primarily intended for office and industrial real estate professionals which allows them to use the Database to analyze leasing options, market conditions and competitive property positions, and to produce multimedia presentations, and
(ii) CrosTrac, a product primarily intended for participants in the office real estate industry which allows them to identify the most likely tenants to fill space vacancies, to find tenants needing representation for their space needs, and for business-to-business marketing. The Combined Company also derives significant revenue from Interactive Advertising and Jamison Reports. Interactive Advertising provides clients with a means of direct access to real estate professionals by allowing placement of advertisements of properties for lease or sale directly in the Company's software products and on the Company's web site. The Combined

3

Company plans to expand its distribution of Jamison Reports, a collection of quarterly market conditions reports, on a national basis. The Company is also developing several new software products to allow clients to better utilize the Database, including CoStar I/S, a software product that will provide extensive detail on commercial properties offered for sale.

The Company believes that it has a number of competitive advantages relative to its actual and potential competitors including:

o The significant cost of developing a database that is as comprehensive or up-to-date as the Database;

o Software products that have, as a result of extensive upgrades, market reseach and input from clients, become full service solutions to client needs;

o Being the first to capitalize on the trend to outsource research and data collection in a manner that would be difficult to duplicate;

o Data, software and methodologies that have become the standard for clients as well as a reliable third-party data source for the media;

o The ability to expand rapidly and efficiently into new markets at relatively low cost;

o A unique ability to offer consistent methodology and quality in multi-market office and industrial real estate information; and

o Long-standing formal and informal relationships with key participants in the office and industrial real estate market.

According to the Federal Reserve, the inventory of commercial real estate in the United States has been valued at approximately $3.3 trillion. The Company estimates that the value of annual transactions for the sale and lease of office and industrial real estate in the United States was $175 billion in 1997. The Company believes that the market for office and industrial real estate information, though undefined today, is vast based on the volume and value of commercial real estate transactions and the large number of parties involved in such transactions. To effect these transactions, real estate brokers representing lessors and tenants, and buyers and sellers, need comprehensive, accurate and consistent building-specific information to advise their clients. From its inception, the Company has sought to consolidate research and software development efforts and spread the costs of such efforts over its client base in order to deliver more comprehensive, accurate and timely information than any single client could obtain through its individual efforts.

Real estate brokers currently comprise a significant portion of the Company's clients and are the most active users of the Database. Other participants in the commercial real estate industry require and subscribe to various subsets of the building-specific information found in the Database. These clients include owners and investors, providers of goods and services to buildings and tenants, and public service agencies. The Combined Company has over 1,900 clients, including leaders of the commercial real estate industry such as CB Commercial Real Estate Group, Inc., Merrill Lynch & Co., Julien J. Studley, Inc., Jones Lang Wootton USA, and LaSalle Partners, Inc. Many of these national companies have multi-year, multi-market contracts with the Company. These multi-market contracts strengthen the Company's position within the industry and ease the Company's entry into new markets by providing an initial client base. In many instances, the Company's entry into new markets has been facilitated by demand from these industry leaders.

The Company's objective is to become the preeminent provider of building-specific information to the commercial real estate industry and related industries in the United States and in select international markets. There can be no assurance that the Company will achieve its objective. The principal components of the Company's strategy are:

4

o Maintain and Improve the Database. The Company intends to maintain the leading position of the Database by expanding its geographic coverage and depth and by consistently auditing and improving the Company's model for collecting the underlying data to help ensure it remains comprehensive and reliable.

o Maintain Technology Leadership. The Company intends to provide ongoing upgrades of its software products to incorporate advances in technology and to provide features and advantages to facilitate ease of use and flexibility for the Company's clients.

o Enter New Markets. The Company plans to continue its aggressive geographic expansion in the United States and in select international markets. The Company, independently, or in connection with strategic acquisitions of local providers, intends to gain an initial foothold in each new target market with one of the Company's products, and then over time, introduce all of its products in that target market.

o Increase Market Penetration and Revenue in Established Markets. The Company will seek to increase revenue from existing clients by increasing the performance and use of the Company's existing products. In addition, the Company has not yet introduced all of its products in all of its markets. Over the next several years, the Company intends to increase revenue by introducing its full complement of products in all of its markets.

o Introduce New Products to Satisfy Existing Client Needs and Reach New Clients. The Company believes the Database contains a wealth of information that can be packaged to create an array of new products to satisfy existing client needs and reach new clients. The Company currently has several new products under development.

The Company was formed in February 1998 by RIGINC and RIGLP to acquire, directly or indirectly, all of the outstanding equity interests in RIGINC, RIGLP and Jamison. RIGINC, which was incorporated and organized initially in the District of Columbia, operated the Company's business until November 1994 (RIGINC was reincorporated under the laws of Delaware in 1996). RIGINC was formerly known as "Realty Information Group, Inc."; in connection with the formation of the Company and this Offering, RIGINC was renamed "OLD RIG, Inc." RIGLP, a Delaware limited partnership, was organized by RIGINC in November 1994 to hold and operate the Company's business. The Company maintains its executive offices at 7475 Wisconsin Avenue, Bethesda, Maryland 20814. The Company's telephone number is (301) 215-8300.


The Company has filed applications in the United States, Canada and the United Kingdom for the CoStar(Reg. TM) and CrosTrac(Reg. TM) marks. All other trademarks and trade names referred to in this Prospectus are the property of their respective owners.

----------

(1) The allocation of the 2,700,000 shares in this Offering between the Company and the Jamison Selling Stockholders assumes an initial public offering price of $11.00, a purchase price for Jamison equal to $10.0 million, and that the Jamison Selling Stockholders will exercise their right to register and sell 65% of the shares received by them in the Offering. If the initial public offering price is higher or lower, the relative number of shares registered by the Jamison Selling Stockholders and the Company will be adjusted accordingly. The Company presently intends to issue and sell in the Offering the number of shares that is the difference between 2,700,000 and the number offered by the Jamison Selling Stockholders. However, the Company reserves the right prior to the closing of the Offering to adjust further the number of shares to be issued by it.

(2) Assumes an initial public offering price of $11.00 per share. This does not include (i) up to 270,000 shares of Common Stock issuable upon exercise of the Over-Allotment Option, (ii) 409,297 shares that will be reserved for issuance upon the exercise of Company options to be issued in exchange for currently outstanding options, exercisable at a weighted average exercise price of $3.30 per share, (iii) 46,695 shares that will be reserved for issuance upon exercise of Company warrants to be issued in exchange for currently outstanding warrants at an exercise price of 10% less than the price at which the shares are being offered hereby, and (iv) approximately 350,000 shares that will be reserved for issuance upon the exercise of options expected to be granted in connection with the Offering. See "Underwriting," "Management -- Employee Benefit Plans," "Description of Capital Stock" and "Certain Transactions."

(3) There is currently no market for the Common Stock, and there can be no assurance that a market for the Common Stock will develop or be sustained after the Offering. The Company has applied to have the Common Stock quoted on the Nasdaq National Market. There can be no assurance, however, that such application for quotation will be approved, or if approved, that listing of the Common Stock will be maintained. See "Risk Factors -- No Prior Public Market; Determination of Offering Price; Share Price Volatility."

TRANSACTIONS IN CONNECTION WITH THE OFFERING

The Company will consummate a series of related transactions in connection with the Offering. Pursuant to a Contribution Agreement dated March 5, 1998 (the "RIG Contribution Agreement"), RIGLP and RIGINC will be consolidated with the Company. Limited partners of RIGLP (other than RIGINC) and all of the stockholders of RIGINC will receive 3.113 shares of the Common Stock of the Company for each limited partnership unit or share of common stock exchanged. See "Certain Transactions." As a result, the Company will own (directly or indirectly) all of the capital stock of RIGINC and all of the equity of RIGLP.

Pursuant to a Contribution Agreement dated February 17, 1998 (the "Jamison Contribution Agreement"), Jamison will be consolidated with the Company in a transaction in which the stockholders of Jamison will contribute all of the outstanding capital stock of Jamison to the Company in exchange for $10 million of the Common Stock of the Company valued at the price at which Common Stock is sold in the Offering. As provided in the Jamison Contribution Agreement, the Company will offer for resale by the Jamison Selling Stockholders as part of the Offering up to 65% of the shares of the Common Stock issued to them pursuant to the Jamison Contribution Agreement.

The consolidations contemplated by the RIG Contribution Agreement and the Jamison Contribution Agreement and the Offering are an integrated transaction intended to qualify under Section 351 of the Internal Revenue Code of 1986, as amended (the "Transaction").

(1) The statement of operations and balance sheet data for 1993 through March 31, 1998 give effect to the contribution to the Company of all of the outstanding equity interests in its predecessors, RIGINC and RIGLP, in exchange for the Company's shares at a rate of 3.113 shares of Company Common Stock for each share of RIGINC or unit of RIGLP as if it had been consummated on January 1, 1993.

(2) The pro forma statement of operations and other operating data for the year ended December 31, 1997 and the three months ended March 31, 1998 gives effect to the Jamison Acquisition as if it had been consummated on January 1, 1997, while the pro forma balance sheet data as of March 31, 1998 assumes the Jamison Acquisition occurred on March 31, 1998.

(3) Reflects charges of approximately $1.1 million and $275,000 for 1997 and the three months ended March 31, 1998, respectively, resulting from the amortization of capitalized product development acquired through the Jamison Acquisition.

(4) Includes gain from sale of assets amounting to $893,000.

(5) Includes shares of the Company's predecessors converted at a rate of 3.113 shares per share of RIGINC or unit of RIGLP and the shares issued to the Jamison stockholders in connection with the Jamison Acquisition. Stock options and warrants outstanding have been excluded from the calculation because their effect is anti-dilutive.

(6) The Company anticipates a one time write-off of acquired in process research and development amounting to $3.0 million resulting from the Jamison Acquisition. This charge to earnings has been reflected in the pro forma Balance Sheet data, but has been excluded from the pro forma Statement of Operations data.

(7) Adjusted to reflect the sale of 2,109,091 shares of Common Stock offered by the Company and the application of the net proceeds from the Offering. Additionally, reflects the use of proceeds for the repayment of the RIGLP line of credit of $1,000,000 and its subordinated debt to RIGINC totaling $650,000 (which sum was loaned to RIGINC by one of its stockholders) and the advances from stockholders of Jamison of $110,000 and other long-term debt of Jamison amounting to $61,000. See "Certain Transactions."

AVAILABLE INFORMATION

As of the effective date of the Registration Statement, the Company will become subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and, in accordance therewith, will file reports, proxy statements and other information with the Securities and Exchange Commission (the "Commission"). The Company intends to furnish its stockholders with annual reports containing financial statements audited by independent accountants and other periodic reports as the Company may deem appropriate or as may be required by law.

RISK FACTORS

An investment in the shares of the Company's Common Stock involves a high degree of risk. The following factors, in addition to the other information in this Prospectus, should be carefully considered in evaluating the Company and its business before purchasing shares of Common Stock. Each of these factors could have a material adverse effect on the Company's business, financial condition and results of operations and on the price of the Common Stock.

This Prospectus contains forward-looking statements about business strategies, market potential, future financial performance and other matters. In addition, when used in this Prospectus, the words "intends to," "anticipates," "expects" and similar expressions are intended to identify forward-looking statements. Such statements involve many risks and uncertainties that could cause actual results to differ materially from such statements, including, without limitation, those risks and uncertainties described, in this Section on "Risk Factors."

History of Operating Losses and Accumulated Deficit; Expected Losses; Uncertainty of Future Profitability. By reason of its continuing investment in expansion and new products, the Company has never recorded an overall operating profit and had an accumulated deficit of approximately $11.8 million as of March 31, 1998. The Company intends to continue to invest in expansion and, therefore, to sustain substantial losses for the next several years. The ability of the Company to achieve overall profitability will largely depend on its ability to generate revenue from its products and services in excess of its investment in geographic and product expansion. There can be no assurance that the Company will be able to generate revenue that is sufficient to achieve profitability, to maintain profitability on a quarterly or annual basis or to sustain or increase its revenue growth in future periods.

Uncertainty of Operating Results. The Company's revenue and operating results may fluctuate as a result of a variety of factors, including: the loss of clients or revenue due to consolidation in the real estate brokerage and investment industry; changes in client budgets; investments by the Company in marketing or other corporate resources; acquisitions of other companies or assets; the timing of new product introductions and enhancements; sales and marketing promotional activities; and general economic conditions.

Uncertainties Associated with Planned Market and Product Expansion. The Company's future success and financial performance will depend in large part on its ability to enter several additional markets contemporaneously and successfully, while continuing to develop and market its products and services in a rapidly evolving information technology environment. To succeed, the Company believes it will be necessary to further increase its geographic coverage and broaden its product lines and client mix. These efforts are expected to impose additional burdens on the Company's research, systems development, sales and general managerial resources. There can be no assurance that the Company will be able to manage this growth successfully.

The Company's future success and financial performance also will depend on its ability to meet the increasingly sophisticated needs of its clients through the timely development and introduction of new and enhanced versions of its products and services. Continuing product development efforts have been and are expected to be required to sustain the Company's growth. Such efforts have inherent risks. There can be no assurance that the Company will be successful in entering new markets or in developing and marketing new or enhanced products and services, or will not experience significant delays in the introduction of new products and services. In addition, there can be no assurance that new or enhanced products or services developed by the Company will meet the requirements of its prospective clients and achieve market acceptance. See "Business -- Strategy," "-- Database" and "-- Products and Services."

Dependence on Integrity and Reliability of Software and the Database. The Company's success is highly dependent on its clients' confidence in the comprehensiveness, accuracy and reliability of the Database and the software accessing the Database. Although the Company believes that it takes adequate precautions to safeguard the completeness and consistency of the data in the Database, and that the information contained in the Database is generally current, comprehensive and accurate, the task of establishing and maintaining

9

such quality during growth is challenging. Similarly, it requires substantial effort and expense to maintain and improve the software that allows clients to access the Database. There can be no assurance that the Company can sustain those efforts. See "Business -- Strategy," "-- Database" and "-- Products and Services."

Dependence on the Real Estate Industry. The Company's business is dependent on the real estate industry and related industries that supply goods or services to, or invest in, the real estate industry. Therefore, changes in the real estate market may affect demand for the Company's products. The real estate industry traditionally has been subject to cyclical economic swings, which could adversely affect the Company's business. Moreover, the real estate industry is undergoing a period of consolidation, often motivated by a desire to reduce expenses. Such consolidation could erode the Company's existing client base, reduce the size of the Company's target market and create enterprises with sufficiently greater bargaining power to cause price erosion which could affect the Company's products and services.

Dependence on Key Personnel. The success of the Company and of its business strategy is dependent in large part on its ability to retain and attract key management and operating personnel, including its President and Chief Executive Officer, Andrew C. Florance. Highly skilled technical, sales, managerial and marketing personnel are in high demand and are often subject to competing offers. Given its plans to expand rapidly, the Company will have an ongoing need to increase the number of management and support personnel. The Company employs a variety of measures to retain and attract key management and operating personnel, including multi-year employment agreements containing confidentiality and non-competition agreements, a stock option plan and incentive bonuses for its key executive officers, and the Company is the beneficiary of a $1 million key person life insurance policy on Mr. Florance. These measures may not be sufficient to permit the Company to attract necessary personnel or to offset the impact of the Company's loss of Mr. Florance or other key employees. See "Management."

Dependence on Proprietary Rights. The Company has made significant investments in the Database, software, methodologies, and other technology and relies on a combination of trade secret and copyright laws, nondisclosure and other contractual provisions, and technical measures to protect its proprietary rights in those assets and technologies. There can be no assurance that these protections will be adequate or that the Company's competitors will not independently develop methodologies, databases or technologies that are substantially equivalent or superior to those of the Company. In addition, there can be no assurance that the legal protections and precautions taken by the Company will be adequate to prevent infringement or misappropriation of the Company's proprietary rights and assets. See "Business -- Proprietary Rights."

Risk of Third Party Claims for Infringement. There can be no assurance that third parties will not bring copyright or trademark infringement claims against the Company or claim that the Company's use of certain technologies violates a patent. Because the Company relies on certain technology which is licensed from third parties, including software integrated with the internally-developed software and used in the Company's products to perform key functions, the Company may be subject to litigation to defend against claims of infringement of the rights of others, or to determine the scope and validity of the intellectual property rights of others. Although the Company does not believe that its products infringe the proprietary rights of third parties, there can be no assurance that infringement or invalidity claims (or claims for indemnification resulting from infringement claims) will not be asserted or prosecuted against the Company or that any such assertions or prosecutions will not materially adversely affect the Company's business, operating results or financial condition. Regardless of the validity or the successful assertion of such claims, defending against such claims could result in significant costs and diversion of resources with respect to the defense thereof. In addition, the assertion of such infringement claims could result in injunctions preventing the Company from distributing certain products. If any claims or actions are asserted against the Company, the Company may seek to obtain a license to such intellectual property rights. There can be no assurance, however, that such a license would be available on reasonable terms or at all.

Identification and Integration of Acquisitions. Through the Jamison Acquisition, the Company is expanding its market and product line with complementary businesses, products, databases, and technologies. The strategy of acquisition versus internal development may be applied as the Company expands further. Acquisitions involve numerous risks, including managing the integration of personnel and products, managing geographically remote units, the diversion of management's attention from other

10

business concerns, the inherent risks in entering markets the Company has either limited or no direct experience in and the potential loss of key employees or clients of the acquired companies. There can be no assurance that the Company will not incur unforseen difficulties in connection with integration of any acquisition. Future acquisitions if pursued and consummated by the Company, could result in dilutive issuances of equity securities, the incurrence of additional debt, one-time write-offs and the creation of substantial amortization expenses arising from goodwill or other intangible assets.

Future Additional Capital Requirements; No Assurance Capital Will Be Available. Since its inception, the Company has financed its operations through cash provided by operations, the sale of equity and borrowings. If the Company proves unable to generate sufficient revenue to fund its operations in the future, the Company may be required to raise additional funds to meet its capital and operating requirements through public or private financing, including equity financing. Any additional equity financing may be dilutive to stockholders, and debt financing, if available, will require payment of interest and may involve restrictive covenants that could impose limitations on the operating flexibility of the Company. Adequate funds for the Company's operations may not be available when needed and, if available, may not be on terms attractive to the Company. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources."

Technological Change. Outsourcing the collection, storage, management and dissemination of commercial real estate information from a centralized database is a recent and evolving development. As a developing market, the requirements are rapidly evolving to meet changing and increasingly sophisticated client needs, frequent new product introductions, and new industry standards. In addition, as the computer and software industries continue to experience rapid technological change and the Internet continues to grow, the Company must be able to quickly and successfully adapt its products to allow them to continue to integrate well with the other computer platforms and software employed by its clients. There can be no assurance that the Company will avoid difficulties that could delay or prevent the successful development and introduction of product enhancements or new products in response to technological changes. See "Business -- Products and Services."

Competition. The market for information systems and services in general is highly competitive and rapidly changing, with the principal competitive factors including the quality and depth of the underlying databases, the responsiveness and flexibility of software, the proprietary nature of research methodologies and databases, the usefulness of the data and reports generated by the software, compatibility with the client's existing information systems, potential for product enhancement, price and the effectiveness of sales, client support, and marketing efforts. While the Company believes its products and services are differentiated favorably from those offered by competitors providing information in the office and industrial real estate industry, competitors may develop or acquire the capacity to narrow or eliminate these differences. Additional competitors may also enter the market and competition may intensify. The Company also faces competition from internal information services at individual real estate brokerage firms, real estate investment institutions and lenders, many of which have developed their own databases. See "Business -- Competition."

Business Interruption. The Company's operations are dependent upon its ability to protect the Company's Database, computers, telecommunications equipment, software systems and facilities against damage from fire, power loss, telecommunications interruption or failure, natural disaster and other similar events. In the event the Company experiences an interruption or permanent loss of one or more of these systems or facilities through casualty, equipment malfunction or otherwise, the Company's business could be adversely affected. The Company's core computer servers and networking systems are located in a climate-controlled, fire and security-protected central location and all data contained in the Database is subject to offsite backup storage. Such protections may not, however, adequately protect the Company or compensate the Company for all losses that it may incur.

Shares Eligible for Future Sale; Registration Rights. Sales of substantial amounts of Common Stock by any of the initial investors in the public market after the Offering could adversely affect the prevailing market price for the Common Stock and could impair the Company's future ability to raise capital through offerings of its equity securities. In addition to the 2,700,000 shares offered hereby, a total of

11

5,911,635 shares held by the directors, officers and other stockholders of the Company will become available for sale in the public market upon the expiration of certain agreements entered into between the stockholders and the Underwriters, subject to the provisions of Rule 144 of the Securities Act. In addition, the Company intends to file, as soon as practicable, a registration statement under the Securities Act to register an aggregate of 1,450,000 shares of Common Stock issued or reserved for issuance under the Company's employee benefit plans. See "Management," "Shares Eligible for Future Sale" and "Underwriting."

After the Offering, the holders of approximately 2,659,700 shares of Common Stock, will be entitled to certain rights to cause the Company to register the sale of such shares under the Securities Act, beginning six months after the Offering. Holders with such rights could cause a large number of shares to be registered and to become freely tradable without restrictions under the Securities Act. Such sales may have an adverse effect on the market price for the Common Stock and could impair the Company's ability to raise capital through an Offering of its equity securities. See "Description of Capital Stock -- Registration Rights."

No Prior Public Market; Determination of Offering Price; Share Price Volatility. There has been no public market for the Common Stock. There can be no assurance that an active public market for the Common Stock will develop or be sustained after the Offering. The initial public offering price will be determined by negotiations between representatives of the Company and the Representatives, consistent with the rules of the National Association of Securities Dealers, of which the Representatives are members, and may not be indicative of future market prices. See "Underwriting" for information related to the method of determining the initial public offering price. The trading price of the Common Stock could be subject to wide fluctuations in response to quarter-to-quarter variations in operating results, changes in earnings estimates by analysts, announcements of technological innovations or new products by the Company or its competitors, general conditions in the real estate or software industries, developments or disputes concerning copyrights or proprietary rights, regulatory developments and economic or other factors. In addition, in recent years the stock market in general, and the shares of information and software related companies in particular, have experienced extreme price fluctuations. This volatility has had a substantial effect on the market prices of securities issued by many companies for reasons unrelated to the operating performance of the specific companies. These broad market fluctuations may adversely affect the market price of the Common Stock. See "Underwriting."

Potential Influence by Principal Stockholder; Benefits of Offering to Current Shareholders. Following completion of the Offering, assuming that the Underwriters' Over-Allotment Option is not exercised, Michael R. Klein, the Chairman of the Board of the Company, will beneficially own 24.3% of the outstanding shares of Common Stock. As a result, Mr. Klein will have the potential ability to exercise substantial influence over the Company's business by virtue of his voting power with respect to the election of directors and all other matters requiring action by stockholders. Such concentration of share ownership may have the effect of discouraging, delaying or preventing a change in control of the Company. The existing shareholders of the Company and the Jamison Selling Stockholders will receive certain benefits from the sale of the Common stock offered hereby. The Offering may establish a public market for the Company Stock and provide increased liquidity for the Common Stock they will own after the Offering, subject to certain limitations. See "Shares Eligible for Future Sale." The existing shareholders of the Company and the Jamison Selling Stockholders will have a substantial unrealized gain in the Common Stock that they will continue to hold after the Offering over the original cost of the equity interests exchanged for such Common Stock. See "Dilution." The Jamison Selling Stockholders will receive approximately $6.5 million in gross proceeds from the sale of approximately 590,909 shares of Common Stock in the Offering. A portion of the net proceeds of the Offering to the Company will be used to repay approximately $650,000 of indebtedness owed to Mr. Klein, and the Jamison Selling Stockholders will be released from obligations of approximately $180,000 of indebtedness of Jamison that the Company intends to repay with proceeds from the Offering. See "Use of Proceeds" and "Certain Transactions."

Effect of Certain Charter and Bylaw Provisions. The Company's Certificate of Incorporation and Bylaws contain certain provisions that could discourage potential takeover attempts and make attempts by the Company's stockholders to change management more difficult. Such provisions include: (i) the

12

requirement that the Company's stockholders follow an advance notification procedure for certain stockholder nominations of candidates for the Board of Directors of the Company (the "Board") and for new business to be conducted at any meeting of the stockholders; (ii) certain limits on the ability of stockholders to call special meetings; and (iii) no stockholder action by written consent. The Certificate of Incorporation also allows the Board to issue up to 2,000,000 shares of preferred stock and to fix the rights, privileges and preferences of those shares without any further vote or action by the stockholders. The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred shares that may be issued by the Company in the future. While the Company has no present intention to issue any shares of preferred stock, any such issuance could have the effect of making it more difficult for a third party to acquire a majority of the outstanding voting stock of the Company. In addition, the Company is subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which prohibits the Company from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date on which the person first becomes an "interested stockholder," unless the business combination is approved in a prescribed manner. The application of these provisions could have the effect of delaying or preventing a change of control of the Company, which could adversely affect the market price of the Company's Common Stock. See "Description of Capital Stock."

Dilution to New Investors; Absence of Dividends. Purchasers of shares of Common Stock in the Offering will experience immediate and substantial dilution of $8.32 per share in pro forma net tangible book value per share. In addition, purchasers of shares of Common Stock in the Offering will incur additional dilution to the extent outstanding options and warrants are exercised. See "Dilution." The Company has never declared or paid any dividends on the Common Stock and does not anticipate paying any dividends on the Common Stock in the foreseeable future. See "Dividend Policy."

USE OF PROCEEDS

The gross proceeds to be received by the Company from the sale of an estimated 2,109,091 shares of Common Stock in the Offering are estimated to be $23.2 million, assuming an initial public Offering price of $11.00 per share. Net proceeds after deducting underwriting discounts and commissions and other expenses of the Offering will be approximately $20.6 million ($23.4 million if the Over-Allotment Option is exercised in full). The Company plans to use those net proceeds primarily to fund the continued geographic and product expansion of the Company's business and increasing its sales and marketing activities. The Company also intends to use the net proceeds to (i) repay certain indebtedness aggregating $1.83 million (consisting of (a) a $1.0 million loan from Silicon Valley Bank to RIGLP and RIGINC, bearing interest at a rate of prime plus two percent, and maturing on October 5, 1998 (this loan accelerates on, among other things, a transfer of all of the equity interests in the borrower), (b) three loans to RIGLP subordinate to the Silicon Valley Bank loan aggregating $650,000 from RIGINC (which sum was loaned to RIGINC by Michael R. Klein; see "Certain Transactions"), bearing interest at a rate of prime plus two percent, and maturing on December 31, 1998 (or upon the acceleration of the Silicon Valley Bank loan) and (c) debt of Jamison in the amount of approximately $180,000),
(ii) to develop corporate information systems and (iii) to provide funds for working capital and other general corporate purposes. Although the Company regularly reviews acquisition proposals involving other businesses, products or technologies complementary to the Company's business, there are currently no agreements or negotiations with respect to any acquisitions. Pending such uses, the Company intends to invest the net proceeds of this Offering in interest bearing, investment-grade securities. The Company will not receive any of the net proceeds from the sale of Common Stock by the Jamison Selling Stockholders.

DIVIDEND POLICY

The Company has never declared nor paid any dividends on its Common Stock, and does not plan to do so for the foreseeable future. Instead, the Company intends to invest any earnings in the operations, development and growth of its business. The holders of Common Stock are entitled to receive ratably such dividends as are declared by the Board of Directors out of funds legally available therefor. The payment of future dividends on the Common Stock and the rate of such dividends, if any, will be determined in light of any applicable contractual restrictions limiting the Company's ability to pay dividends, the Company's earnings, financial condition, capital requirements and other factors deemed relevant by the Board of Directors.

DILUTION

As of March 31, 1998, after giving pro forma effect to (i) the consolidation of the Company with its predecessors, RIGINC, and RIGLP, in exchange for the Company's shares at a rate of 3.113 shares of Company Common Stock for each share of RIGINC or unit of RIGLP and (ii) the consolidation of the Company with Jamison in exchange for approximately 909,091 shares of Company Common Stock, the Company had a pro forma net tangible book value of approximately $3.3 million or $0.49 per share of Common Stock. Pro forma net tangible book value per share represents the amount of the Company's total pro forma tangible assets, less total pro forma liabilities, divided by the 6,820,726 shares of Common Stock outstanding after the Jamison Acquisition but prior to the Offering. See Unaudited Pro Forma Condensed Combined Financial Statements and "Prospectus Summary -- Transactions in Connection with the Offering."

Without taking into account any other changes in the pro forma net tangible book value of the Company after March 31, 1998, other than to give effect to the sale of 2,109,091 shares offered hereby at the assumed initial offering price of $11.00 per share and receipt of the net proceeds therefrom and the application of a portion of the Offering to repay certain outstanding indebtedness as set forth under "Use of Proceeds," the Company's pro forma net tangible book value, as adjusted at March 31, 1998 would have been approximately $23.9 million or $2.68 per share. This represents an immediate increase in pro forma net tangible book value of $2.19 per share to existing stockholders and immediate dilution in pro forma net tangible book value of $8.32 per share to purchasers of Common Stock in the Offering, as illustrated in the following table:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements which involve risks and uncertainties. The Company's actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under "Risk Factors" and elsewhere in this Prospectus. See "Special Note Regarding Forward-Looking Statements and Risk Factors." The following discussion also should be read in conjunction with the Selected Consolidated Financial Data and the historical financial statements and related notes thereto appearing elsewhere in this Prospectus.

OVERVIEW

The Company is a leading provider of comprehensive, building-specific information to the United States commercial real estate industry and related industries. During the period from 1994 through 1997, the Company expanded the geographical coverage of its products and developed new products. This expansion included acquisitions made by the Company in 1996 and 1997 in Chicago and San Francisco, respectively. See "Business -- Overview." In connection with the Offering, the Company will acquire Jamison, a commercial real estate information provider with operations in Atlanta and Dallas/Fort Worth. See "-- Jamison Acquisition." See "Business -- Overview." The Company currently generates positive cash flow from operations in each region that has operated for at least 18 months. Costs associated with the introduction of new products into these established regions may result in net losses in such regions in the future. Because of the Company's growth strategy, costs incurred in expanding into new regions and introducing new products to existing markets have resulted in substantial overall net losses and negative cash flow from operations. As each regional operation and each product becomes established, the revenue produced generally exceeds operating costs and generates profits and cash flow from operations. Management expects that proceeds from the Offering will be used primarily to continue the rapid expansion into new regions and the development and introduction of new products. Therefore, while existing regions are expected to grow in profitability and provide substantial funding for the business, the expansion is expected to generate substantial losses and negative cash flow from overall operations for at least the next two years.

Approximately 95% of the Company's revenue in 1997 was derived from one-year to three-year contracts that generally renew automatically. Upon renewal, many of the contract rates increase automatically in accordance with contract provisions or as a result of renegotiation. The Company currently experiences CoStar contract renewal rates in excess of 90%. Clients pay contract fees on an annual, quarterly or monthly basis. The Company recognizes this revenue on a straight line basis beginning with the installation or renewal date over the life of the contract. Annual and quarterly advance payments result in deferred revenue, which substantially reduces the working capital requirements generated by the growth in the Company's accounts receivable. Approximately 5% of the Company's revenue in 1997 was derived from the sale of advertising products.

Comparison of March 31, 1997 and March 31, 1998

Revenue. Revenue increased 83% from $1.6 million for the three months ended March 31, 1997 to $2.8 million for the three months ended March 31, 1998. This increase in revenue resulted principally from growth of CoStar in the established regions and growth in new regions entered during 1997. Advertising revenue increased 174% from $69,000 for the three months ended March 31, 1997 to $189,000 for the three months ended March 31, 1998. This increase reflects the expansion of the advertising product in the established regions.

Gross margins. Gross margins increased 131% from $838,000 for the three months ended March 31, 1997 to $1.9 million for the three months ended March 31, 1998, improving from 54% to 68% of revenue, respectively. This increase resulted principally from the expanding revenue and profitability of the established regions, including Washington, D.C., New York, Los Angeles and Chicago.

Selling and marketing expenses. Selling and marketing expenses increased 46% from $863,000 for the three months ended March 31, 1997 to $1.3 million for the three months ended March 31, 1998, but decreased as a percentage of revenue from 55% to 45%, respectively. Selling and marketing expenses increased as the company expanded its sales organization into new markets and developed and introduced new products to its existing client base.

General and administrative expenses. General and administrative expenses increased 34% from $672,000 for the three months ended March 31, 1997 to $899,000 for the three months ended March 31, 1998, but decreased as a percent of revenue from 43% to 32%, respectively. General and administrative expenses increased due to additional personnel required to support an expanding organization and client base.

Interest and other income (expense). Interest income decreased from $31,000 for the three months ended March 31, 1997 to an expense of $38,000 for the three months ended March 31, 1998 as a result of borrowing on lines of credit used to fund the operations of the Company.

Comparison of 1997 and 1996

Revenue. Revenue grew 84% from $4.3 million in 1996 to $7.9 million in 1997. This increase in revenue resulted principally from growth in the Company's client base in all regions of the country, expansion into new regions, expansion of product lines into existing regions, and introduction of new products. Revenue from regions considered established at December 31, 1997 grew from $4.3 million in 1996 to $7.3 million in 1997, an increase of 70%. A portion of this growth resulted from a full year of operation in the Chicago region in 1997, which the Company entered on April 1, 1996 through the

20

acquisition of Chicago Resource, Inc. New regions entered and generating revenue during 1997 include San Francisco, through the purchase of 99.3% of the capital stock of NMS, Inc., and Philadelphia, both entered in the first quarter of 1997, and Boston, entered in the fourth quarter of 1997. Advertising revenue, generated primarily in established regions, increased 232% from $122,000 in 1996 to $405,000 in 1997, reflecting the initial impact of investments in the advertising product.

Gross margins. Gross margins increased from $2.1 million in 1996 to $4.5 million in 1997, improving from 50% to 57% of revenue. This increase resulted principally from the expanding revenue and profitability of established regions, including Washington, D.C., New York, Los Angeles and Chicago.

Selling and marketing expenses. Selling and marketing expenses increased 63% from $2.7 million in 1996 to $4.4 million in 1997, but decreased as a percentage of revenue from 63% in 1996 to 56% in 1997. Selling and marketing expenses increased as the Company expanded its sales organization into new markets and the Company invested in the development of the advertising sales area. Selling expenses declined as a percent of revenue due to sales growth during the year and the growing renewable contract base.

General and administrative expenses. General and administrative expenses increased 58% from $1.9 million in 1996 to $3.0 million in 1997, but decreased as a percentage of revenue from 43% in 1996 to 38% in 1997. General and administrative expenses increased due to new hires required to support the expanding organization and client base, as well as increases in occupancy and communication costs. General and administrative expenses decreased as a percentage of revenue due to the Company's ability to leverage these expenses over its growing revenue.

Interest and other income. Interest income increased from $30,000 in 1996 to $49,000 in 1997 due to higher average cash balances in 1997 resulting from a capital investment of $4.8 million in the Company in December 1996.

Comparison of 1996 to 1995

Revenue. Revenue increased 105% from $2.1 million in 1995 to $4.3 million in 1996. This increase in revenue resulted from rapid growth in the Company's client base, principally in the New York and Washington regions, which accounted for $1.2 million or 57% of the total growth, and the Company's expansion to new regions. New regions entered and generating revenue in 1996 included Chicago and Los Angeles.

Gross margins. Gross margins increased from $1.1 million in 1995 to $2.1 million in 1996 due to the growth in revenue. However, expansion to new regions including Los Angeles and Chicago resulted in new operating costs, primarily the cost of compiling, researching and updating the Company's Database. These costs reached significant levels for each new region and product in advance of revenue growth. Gross margins as a percentage of revenue were therefore reduced from 55% in 1995 to 50% in 1996.

Selling and marketing expenses. Selling expenses increased from $566,000 in 1995 to $2.7 million in 1996 as the Company substantially expanded its sales organization into new regions and enhanced its selling efforts in existing regions, particularly New York.

General and administrative expenses. General and administrative expenses increased 58% from $1.2 million in 1995 to $1.9 million in 1996. This increase is due to hiring additional personnel required to support the expanding number of regions and growing client base.

Interest and other income. Interest income decreased from $71,000 in 1995 to $30,000 in 1996 as a result of lower average cash balances in 1995.

SUPPLEMENTAL REVENUE AND CONTRIBUTION MARGIN ANALYSIS OF ESTABLISHED REGIONS

Since its inception, the development of the Company's business has required substantial investments for the expansion of products and establishment of operating regions, which has resulted in substantial net losses. These investments continue in certain regions, while other regions have become profitable. Additionally, existing profitable regions may experience reductions in profitability as a result of expansions in the scope of product offerings within the region.

Due to the varying degrees of maturity of the Company's operating regions, management measures a region's performance in relation to the length of time the region has been in operation, along with the relative size of the region and its product offerings. Management believes that financial data for regions that have been in operation for at least 18 months subsequent to the initial release of products can provide relevant information as to the performance and profitability of the Company. Such regions are considered by management to be established, and generally provide substantial operating cash flows that are then invested into the development of new regions.

As of March 31, 1998, the Company's operations in the following regions have been ongoing for more than eighteen months and are considered established:
Washington (includes Baltimore), Chicago, New York (includes Northern New Jersey, Long Island, Westchester, and Connecticut) and Los Angeles (includes Orange County). The following table sets forth supplemental quarterly financial information regarding the regions considered established as of March 31, 1998, which has been derived from the Company's unaudited interim financial statements. This information should be read in conjunction with the entire Prospectus and should not be considered in isolation or as an alternative to other financial measures. This information is not necessarily indicative of the results to be expected for any of the Company's other regions.

Management believes that EBITDA is an indicator of how established regions are performing. However, EBITDA should not be considered as an alternative to net income or loss (as an indicator of operating performance) or to cash flows generated from operating activities (as a measure of liquidity) determined in accordance with generally accepted accounting principles.

(3) EBITDA as a percentage of revenues.

JAMISON ACQUISITION

In connection with the Offering, the Company will acquire Jamison for Common Stock valued at $10.0 million. Jamison is a real estate information business that has been based in the Atlanta region since 1981 and that expanded to the Dallas region in 1995. In the Offering the stockholders of Jamison are selling up to 65% of the Common Stock received by them in the Jamison Acquisition. The Company will not receive any of the proceeds from the sale of the Common Stock of the Jamison Selling Stockholders. See "Jamison Selling Stockholders." The audited financial statements of Jamison are included elsewhere in this Prospectus. For the year ended December 31, 1997 and the three months ended March 31, 1998, Jamison generated cash from operating activities of $266,000 and $230,000, respectively. This positive cash flow principally results from continued profitable operations in Atlanta and substantial revenue growth in the Dallas region, which has largely eliminated negative cash flow associated with entry into that region.

As a result of the Jamison Acquisition, the Company will allocate $7.0 million of the Jamison purchase price to capitalized product development costs and intangible assets, that will be amortized using estimated lives of two to fifteen years, and $3.0 million to in process research and development which will be charged to operations immediately following the Jamison Acquisition. The estimated charges for amortization of the Jamison capitalized product development and intangible assets are approximately $1.5 million for the first two years, and are expected to decline to approximately $500,000 or less per year thereafter. Approximately $1.1 million of the amortization in each of the first two years relates to capitalized product development and will be charged to cost of sales, reducing gross margins substantially.

The Company will make significant investments to convert Jamison's data, upgrade Jamison's clients to the Company's products and complete the development of certain acquired technology into products which are commercially viable in the Company's other markets. These projects are expected to cost up to $1.0 million to complete, including the cost of programming, consulting, training and research, and are expected to be completed within two years. The Company anticipates that during this period, the positive cash flow expected from the Jamison operation will be largely offset by the costs of this conversion process. There can be no assurance that the conversion and development of Jamison's data, products and clients will be completed in the time planned, or that the cost of these projects will not be greater than estimated.

Comparison of March 31, 1997 and March 31, 1998 of Jamison

Revenue. Revenue increased 28% from $822,000 for the three months ended March 31, 1997 to $1.0 million for the three months ended March 31, 1998. This increase in revenue resulted principally from continued growth of the client base in Atlanta and Dallas.

Gross Margins. Gross margins increased 47% from $471,000 for the three months ended March 31, 1997 to $692,000 for the three months ended March 31, 1998, improving from 57% to 66% of revenue, respectively. This increase resulted principally from the expanding revenue and profitability of the Atlanta and Dallas regions.

Selling general and administrative expenses. Selling general and administrative expenses increased 14% from $461,000 for the three months ended March 31, 1997 to $526,000 for the three months ended March 31, 1998, but decreased as a percentage of revenue from 56% to 50%, respectively. Selling and marketing expenses increased as Jamison expanded its sales organization in Dallas and began focusing on the sale of Jamison Reports in that region. Selling expenses declined as a percent of revenue due to the sales growth experienced during the quarter and the growing renewable subscriber base.

Other income (expenses). Other income decreased from $5,000 for the three months ended March 31, 1997 to an expense of $3,000 for the three months ended March 31, 1998 due to an increase in interest expense.

Comparison of 1997 and 1996 of Jamison

Revenue. Revenue grew 48% from $2.5 million in 1996 to $3.7 million in 1997. This increase in revenue resulted principally from growth in Jamison's client base as well as expansion into the Dallas region. Atlanta, a market entered in 1981, grew approximately $300,000 or 17%, while Dallas revenue increased from approximately $400,000 in 1996 to $1.2 million in 1997.

Gross Margins. Gross margins increased $864,000 from $1.4 million in 1996 to $2.3 million in 1997, improving from 57% to 62% as a percent of sales. This increase resulted principally from the expanding revenue in the Dallas region.

24

Selling, general and administrative expenses. Selling, general and administrative expenses increased 29% from $1.7 million in 1996 to $2.2 million in 1997, but decreased as a percentage of revenue from 66% in 1996 to 60% in 1997. Selling expenses increased as the Company expanded its sales organization into Dallas and began focusing on the sale of Jamison Reports. Selling expenses declined as a percent of revenue due to the sales growth experienced during the year and the growing renewable subscriber base.

Other income (expense). Other expenses increased from $14,000 in 1996 to $35,000 in 1997 due to an increase in interest expense.

LIQUIDITY AND CAPITAL RESOURCES

To date, the Company has financed its operations through cash flow from established regions, the sale of partnership units and the establishment of credit lines with a bank and with a stockholder of the Company. Additionally, the Company receives advance payments from clients on a number of contracts, resulting in the generation of cash as reflected in deferred revenue balances of $969,000, $903,000, and $1.6 million as of December 31, 1996 and 1997 and March 31, 1998, respectively. Increases in accounts receivable due to sales growth expand working capital requirements and reliance on credit lines, but are substantially offset by deferred revenue. As a result of reduced losses and a significant increase in deferred revenue as of March 31, 1998, cash provided by operations for the three months ended March 31, 1998 was $22,000. The Company had a deficit in working capital at March 31, 1998 of $1.9 million, and continues to experience operating losses and negative cash flow as a result of its rapid expansion into new regions, while established regions continue to generate cash flow from operations.

Net cash used in operating activities was $454,000, $1.8 million, and $2.2 million, in 1995, 1996, and 1997, respectively, as a result of the operating losses of the Company. Net cash used in investing activities amounted to $1.7 million in 1997, including the acquisition of NMS, Inc. and capitalized product development, including the cost of building photography, and fixed asset purchases, consisting principally of computer and office equipment. The Company currently has no material commitments for capital expenditures. Management believes that the Company's current resources and commitments for funding are adequate to support its current operations, and based on its current plans, the proceeds of the Offering combined with positive cash flow from the Company's established regions will be sufficient to fund its planned operations and expansion into new regions and products for at least the next two years.

To date, the Company has generated substantial growth through the acquisition of other entities. The Company plans include further growth which may occur through the acquisition of other entities. Acquisitions may vary in size and could be material to the current operations of the Company. The Company expects that it will use cash, stock issuances, or other means of funding to effect such transactions.

To date the Company has operated as either a Subchapter S corporation or a limited partnership, and has not been subject to corporate income taxes. Currently, the Company is a taxable entity. Although the Company has experienced losses to date, future profitability, to the extent it is not offset by the benefits of loss carryforwards, would result in income tax liabilities. The Company does not expect to benefit substantially from tax loss carry forwards generated prior to its formation.

Management does not believe the impact of inflation has significantly affected the Company's operations. Management does not anticipate that the Year 2000 will have a significant impact on its information systems or result in a significant commitment of resources to resolve potential problems associated with this event.

The Combined Database tracks over eight billion square feet of office and industrial space in more than 150,000 buildings, better than twice the coverage of the Combined Company's nearest competitor. The Combined Database also contains detailed information on 120,000 tenants and 13,000 buildings for sale (with an aggregate asking price in excess of $15 billion). In addition, the Company has developed a portfolio of multimedia software products with Internet connectivity that allows clients to access the Database and from which the Company generates revenue in each of its markets.

The Combined Company is the market leader in providing comprehensive office and industrial real estate information in nine of the ten largest United States metropolitan areas. After establishing the Database and software products in the Washington, D.C. metropolitan area, the Company expanded to Baltimore (1992), and thereafter to New York City (1994), Westchester County, Long Island and Northern New Jersey (1995), Los Angeles, Orange County and Chicago (1996), and Philadelphia, San Francisco and Boston (1997). In connection with the Offering, the Company will acquire Jamison, the leading commercial real estate information provider in Atlanta and Dallas/Fort Worth. The Company plans to continue its aggressive geographic expansion in the United States and in select international markets. In most instances, the leading office and industrial real estate brokerage firms in a new market have become the Company's clients within six months of entry. The Company currently generates positive cash flow from operations in each regional market in which it has operated for at least 18 months.

The Company's clients access the Database using the Company's multimedia software products. These software products include (i) CoStar, a product primarily intended for office and industrial real estate professionals which allows them to use the Database to analyze leasing options, market conditions and competitive property positions, and to produce multimedia presentations, and
(ii) CrosTrac, a product primarily intended for participants in the office real estate industry which allows them to identify the most likely tenants to fill space vacancies, to find tenants needing representation for their space needs, and for business-to-business marketing. The Company also derives significant revenue from other products. Interactive Advertising provides clients with a means of direct access to real estate professionals by allowing placement of advertisements of properties for lease or sale, directly in the Company's software products and on the Company's web site. The Combined Company plans to expand its distribution of Jamison Reports, a collection of quarterly market conditions reports, on a national basis. The Company is also developing several new software products to allow clients to better utilize the Database, including CoStar I/S, a software product that will provide extended detail on office and industrial properties offered for sale.

INDUSTRY BACKGROUND

According to the Federal Reserve, the inventory of commercial real estate in the United States has been valued at approximately $3.3 trillion. The Company estimates that the value of annual transactions for the sale and lease of office and industrial real estate in the United States was $175 billion in 1997. The Company believes that the market for office and industrial real estate information, though undefined today, is vast based on the volume and value of commercial real estate transactions and the large number of parties involved in such transactions. Comprehensive and reliable information is a critical component of all transactions in the commercial real estate industry. To effect these transactions, real estate brokers representing lessors and tenants, and buyers and sellers need comprehensive, accurate and consistent building-specific information to enable them to advise their clients. A study by an inde-

26

pendent consulting firm commissioned by the Company found that commercial real estate professionals spend 40% of their work day collecting and analyzing information on the real estate market. In the United States there are currently an estimated 160,000 commercial real estate firms.

The importance of accurate, property-specific information to a broker's business translates both into time (as indicated by the consulting firm's study) and money. Traditionally, large brokerage firms maintained their own research departments to catalogue buildings, space availabilities, properties for sale, market statistics, and other building specific information. Smaller brokerage firms, unable to afford their own research departments, would periodically research the market in response to client requests. Each firm also spent significant resources adapting or developing software to analyze the information it had independently gathered. This fragmented approach resulted in duplication of effort in the collection and analysis of information, excessive internal costs, non-standard data with varying degrees of accuracy and comprehensiveness and, especially for smaller firms, a large information gap. From its inception, the Company has sought to consolidate research and software development efforts and spread the costs of such efforts over all its clients in order to deliver more comprehensive, accurate and timely information than any single client could obtain through its individual efforts.

COMPETITIVE ADVANTAGES

The Company believes that it has a number of competitive advantages relative to its actual and potential competitors including:

o Comprehensive Proprietary Database. The Company's Database is the accumulation of more than ten years of data collection by the Company. This effort includes both direct data collection by the Company and the acquisition of various real estate information providers in various markets who themselves (like Jamison) expended significant effort building their databases. The Combined Database tracks over eight billion square feet of office and industrial inventory and more than 120,000 tenants. The Combined Database also includes photographs of more than 70,000 buildings, believed by the Company to be the largest library of digitized building photographs in existence. The Combined Database is supported and maintained by one of the largest office and industrial real estate listings research staffs in the nation. Whereas the Company's Database costs are mostly related to maintaining the accuracy, currency and integrity of the Database and expanding the Database to cover new markets, the Company believes that any new competitor would have to make substantial expenditures over a number of years to develop a database as comprehensive as the Database.

o Full Service Software and Data Solutions. As the result of numerous upgrades over the last several years, the Company's software products have become a high value-added tool for its clients by providing them with full-service solutions to their needs. Through continuous feedback from clients and a highly sophisticated software platform, the Company has improved its software products to service more of its clients' needs. The Company believes that, because of its size and experience, it will be able to maintain and upgrade this software at a lower cost per client compared to its competitors.

o First to Capitalize on Outsourcing Trend. During the 1990s, many of the Company's clients began outsourcing the collection and assembly of commercial real estate data. A portion of the Company's Database was developed with data contributed by clients that had outsourced their real estate information needs to the Company. In addition, most of the databases that were contributed to the Company no longer exist, as the firms that originally built them (and provided them to the Company) ceased maintaining them when they subscribed to the Company's products and services. As a result, the Company believes that it would be difficult for any new competitor to duplicate this process.

o Standardization on Company Products. Many of the Company's clients have standardized their internal reporting systems on the Company's proprietary data structures. Users of the Company's software have invested significant time mastering the Company's products and understanding its methodologies, so that the Company's clients are likely reluctant to change information suppliers. In addition, a growing number of prominent print and other media outlets are routinely citing the Company as a source for office and industrial real estate data.

27

o Resources to Enter Markets Efficiently. The Company's market coverage, size and experience with geographic expansion allow it to expand rapidly into new markets at a relatively low cost compared to its competitors. New market entry is facilitated because, prior to entry, the Company already has the Database, software products that use the Database, established research and data collection procedures, existing administrative infrastructure, and marketing and sales procedures that have been successful in other markets.

o Sole National Information Provider. The Combined Company is the only provider of uniform, up-to-date and comprehensive data in all of the major markets encompassed by the Combined Database. As a result, the Combined Company has the unique ability to offer significant multi-market real estate information for those markets to national clients who find value in purchasing uniformly-presented data.

o Relationships with Key Clients. As a result of the Combined Company's presence in the nine regions it currently serves, it has developed long-standing formal and informal relationships with key participants in the office and industrial real estate market. The Company is able to capitalize on these relationships when entering new markets and when expanding product lines in existing markets.

STRATEGY

Building upon its competitive advantages, the Company's objective is to become the preeminent provider of building-specific information to the commercial real estate industry and related industries in the United States and select international markets. The principal components of the Company's strategy are:

o Maintain and Improve the Database. Management believes that the Database is the most comprehensive database of building-specific office and industrial real estate information available today. The Company intends to maintain this leading position by continuing to expand the Database's coverage and by constantly auditing and improving the Company's model for collecting the data underlying the Database to ensure it remains comprehensive and reliable.

o Maintain Technology Leadership. The Company intends to provide ongoing upgrades of its software products to incorporate advances in technology and to provide features and advantages to facilitate ease of use and flexibility for the Company's clients.

o Enter New Markets. The Company plans to continue its aggressive geographic expansion in the United States and select international markets. The Company, independently, or in connection with strategic acquisitions of local providers, intends to gain an initial foothold in each new target market with one of the Company's products, and then over time, introduce all of its products in that target market. In order to accomplish this, the Company intends to first expand the Database to include substantially more comprehensive information on office and industrial buildings in the target market than any competitor in that market. The Company believes that favorable references from reputable clients in established markets will enable the Company to accelerate the rate at which it can gain market acceptance in newly entered regions.

o Increase Market Penetration and Revenue in Established Markets. The Company believes that substantial opportunities exist in its established markets to both attract new clients and increase its revenue from existing clients. The Company also seeks to increase revenue from existing clients by increasing the performance and use of the Company's existing products. In addition, the Company has not yet introduced all its products in all of its markets. Over the next several years, the Company intends to increase revenue by introducing its full complement of its products in all of its markets.

o Introduce New Products to Satisfy Existing Client Needs and Reach New Clients. The Company believes its Database contains a wealth of information that can be packaged to create an array of new products, several of which are currently under development. Management intends to sell

28

these new products to satisfy both existing client needs and attract new clients. The Company also intends to attract new clients by expanding its Database to cover additional segments of the commercial real estate industry (such as retail, multi-family and hotels).

THE DATABASE

The Company believes that the Database is the largest and most sophisticated database of office and industrial real estate information available today. It is the basis for all of the Company's products and services. This highly complex database is a real-time information system comprised of more than 100 inter-related tables, containing hundreds of data fields of information. The data fields tracked include such categories as: location, site and zoning information; building characteristics; space availabilities; tax assessments; ownership; sale comparables; mortgage and deed information; for-sale information; and income and expense histories.

The Combined Database is the result of more than ten years of research by the Combined Company. It tracks more than eight billion square feet of office and industrial inventory in more than 150,000 buildings and 1.3 billion square feet of available space on a floor-by-floor, suite-by-suite level in increments as small as 100 square feet. The Combined Database archives valuable historical information such as leasing, occupancy, rental rate and ownership histories. It also contains detailed information on more than 32,000 commercial real estate companies that own, lease and manage properties tracked by the Company. In addition, the Combined Company actively tracks over 120,000 tenants and thousands of lease transactions.

The Combined Database also includes 124,000 building photographs, aerial photographs and floor plans. The Company believes this is the largest library of digitally stored property photographs in existence. These images were collected over a ten year period by dozens of staff and contract architectural photographers nationwide.

DATA COLLECTION

The Company has developed a highly evolved data collection organization, made up of a unique combination of researchers, management systems, computer and communications hardware, and software systems.

Research. The Combined Company has more than 133 researchers collecting and analyzing office and industrial real estate information. The Combined Company's research department updates, on a monthly basis, the majority of the more than 140,000 buildings tracked, through over 500,000 phone calls a year, e-mails, faxes, field inspections, news monitoring and direct mail.

The Company puts every new employee through an extensive training program to maintain a consistent research process. New employees must pass a series of examinations developed by the Company to ensure their technical proficiency in office and industrial real estate, as well as in the Company's internal data collection systems, which are described in greater detail below. The Company's research department is structured into geographic teams of Research Analysts, each led by a Research Manager. This team structure creates opportunities for upward employee mobility and provides the Company with the flexibility to easily redeploy research resources to cover new markets.

Management and Quality Control Systems. The Company has established both automated and non-automated controls to manage the data collection process and to ensure its integrity. Automated measures such as the Contact Management System (CMS) track every contact with individuals and firms in the Database and allow researchers to set call-backs for future data updates. There are a large number of automated data quality tests that check for potential errors including contiguous space, occupancy date conflicts, available square footage greater than building area, typical floor greater than land area, and expired leases.

The Company employs regular non-automated quality control measures as well, monitoring items such as the number of images scanned and photographs taken, to the number of tenants canvassed by tenant canvassers and the number of news stories submitted by researchers. The Company performs

29

regular auditing of all research to check for data accuracy, completeness and quality. Audit methods include calling the leasing contact on properties recently updated to re-verify information collected or reviewing commercial real estate periodicals and newspapers for transactions to determine whether they are reflected in the Database. Field research is performed to determine if buildings were canvassed correctly and to determine if any buildings were missed.

Finally, one of the most important and effective quality control measures is feedback from the thousands of commercial real estate professionals that use the Company's data every day. The Company regularly surveys clients regarding data quality and uses this information to target areas for improvement and to obtain early warnings about any problem areas.

Computer and Communications Hardware. The Company maintains six Novell and/or Windows NT servers in support of the Database and a national internal frame relay network to allow remote researchers real-time access to the Database. The servers are in a secured, firewall-protected environment. The Company also maintains redundant drive arrays and stockpiles hardware spare parts to minimize potential system downtime. The Company stores full data back-ups off site and is evaluating implementing fully-redundant server capacity following the Offering.

Software Systems. The Company uses client server software to manage the Company's internal data collection. In addition, the Company's own systems software has been developed over ten years and contains over 250,000 lines of code. This software enables the Company to continuously improve data integrity and research productivity even as the volume of data tracked has grown exponentially. The system has four primary functions: collecting building-specific data, tracking companies and individuals, facilitating the Company's operations and distributing data.

o Collects Building-Specific Data. Researchers can add or change data relating to buildings, space available for lease, buildings for sale, lease and sale comparables, and other historical data. The system goes well beyond simple data entry. It demands that researchers account for every square foot of available space they add, delete, or modify in the Database. It enforces commercial real estate business guidelines and compels the researcher to record and reconcile available space adjustments in vacancy and occupancy much like making offsetting entries in a general ledger. Though the number of data fields on a specific building has increased dramatically, the system has allowed average researcher productivity to double over the last five years through increased automation. The system enforces referential integrity by ensuring that changes made in one area of the Database are consistent with all related areas of the Database and utilizes comprehensive audit trails to allow management to understand how and why changes were made and by whom. The system is scalable to allow for continued growth in the size of the Database.

o Tracks Companies and Individuals Associated with Commercial Real Estate. The system tracks brokerage firms, tenants, owners, property managers, developers, architects and many others. The system allows employees to track contact and call histories and set automated and manual call-backs. This second function of the Company's software systems is highly integrated with the first. For example, it transforms available space listing updates into actual tenant and tenant deal transaction information.

o Facilitates the Company's Operations. The Company's software systems are utilized by the Company internally in a number of areas including sales, marketing, customer service, administration and accounting. For example, a new leasing agent entered in the system by a researcher is automatically flagged on the sales representative's system as a sales prospect. Later, this same leasing agent may be identified in a query by the marketing department as a direct mail target. After that leasing agent becomes a client, customer service will schedule installation and manage ongoing data delivery through this same system. Finally, the accounting department will handle contract management and accounts receivable communications, all within this same integrated system.

o Distributes Data. The software system automates packaging and delivery of subsets of the Database for client use. This is accomplished through a series of nightly, automated, triggered events. Quality control reports are generated for management, redundant online backups are made and database subsets are compressed for more efficient distribution. Finally, the Database subsets are transported over the Internet to client systems.

PRODUCTS AND SERVICES

The Company has developed advanced proprietary software products utilizing its Database. These products use sophisticated Windows-based programs with Internet connectivity to access the Company's Database and present information in a variety of formats.

CoStar. Introduced in 1991, CoStar is a software product heavily utilized by commercial real estate brokers and increasingly used by building owners, investors and lenders and by goods and service providers such as telecommunications providers, insurance companies and building services vendors. CoStar allows access to utilize the Database to research leasing options, analyze market conditions and competitive property positions, keep abreast of industry news, and produce multimedia client presentations.

The Company's clients use CoStar to find leasing options in office and industrial buildings. The user can query the Database with any combination of pertinent criteria, combining any of approximately one hundred CoStar data fields from categories such building size, location, building characteristics, space availabilities, ownership, or sales comparables. For example, if a CoStar user needs to find an office suite of 5,000 square feet in a high quality building in one of two specific submarkets, the client simply enters these requirements into CoStar and initiates a query. CoStar then searches through hundreds of millions of square feet of space in seconds to find all the available space meeting the search criteria.

The Company's clients also use CoStar to analyze market conditions by calculating up-to-the-minute vacancy rates, absorption rates, or average rental rates. This allows clients to gauge supply and demand balance and track market trends. Clients can also keep abreast of their competitor's market share and how competitors are positioning their properties. In addition, CoStar has a newswire feature that keeps clients informed of late breaking commercial real estate news such as major deals signed, acquisitions, ground breakings and other features.

CoStar allows users to create professional client presentations complete with high-resolution, digital color photographs and aerials of commercial buildings in minutes using a desktop computer and color printer. CoStar further details space availability by providing digital floor-plans indicating "as-built" conditions or typical floors. The user can select from over 50 customizable reports, presenting space availability, comparable sales, tenant activity, market statistics, photographs and floor plans. Preliminary space planning can also be performed on CoStar's floor-plans to help determine feasibility and use. The user can export and edit reports, photos, and floor plans in popular software packages like Microsoft Word, Power Point, WordPerfect, Excel, or Lotus 123. CoStar reports can be edited in Microsoft Word or WordPerfect for Windows to easily customize and print presentations.

CrosTrac. Introduced in 1996, CrosTrac is a software product that delivers detailed information profiling the tenants occupying office buildings to a wide variety of commercial real estate and other clients. Building owners rely upon the product as do commercial real estate brokers, providers of goods and services to building tenants, and providers of goods and services to building owners. These clients use the Database to identify and target the most likely tenants to lease space, to understand trends and the demand for commercial real estate, to identify and target the tenants most likely to need representation for their real estate requirements, and to identify and target the tenants most likely to buy a particular vendor's goods and services.

Commercial real estate professionals use CrosTrac to identify and target the tenants most likely to fill their space vacancies. For example, if a client owns or represents a high quality building in a certain area with an upcoming vacancy of 5,000 square feet, the client might enter two queries to develop both a list of prospects for direct mail marketing and a more focused list for telemarketing. For the first broad list, the client might query for all tenants with leases expiring within the next year who occupy 3,000 to 7,000 square feet of space in buildings that are within the same general area as the client's building. Within seconds, CrosTrac might identify several hundred prospective tenants from a list of tens of thousands of tenants and enable the client to print labels for a mailing to these prospects. For the second, more focused list, the client might use the same query as before, but add a parameter restricting

31

the list to those firms with SIC classifications typically found in high quality buildings, such as law firms or investment banking firms. With the resulting more focused list of dozens of prospective tenants, the client might use CrosTrac's call tracking features and data collection features to assist them in telemarketing the list.

The Company's other clients use CrosTrac to identify and target the tenants most likely to purchase goods and services from the client. For example, companies are more likely to make significant purchases in connection with a move. A furniture vendor specializing in selling economy furniture to mid-size companies therefore might use CrosTrac to query for all tenants who have, for ten years or more, occupied 10,000 to 20,000 square feet in mid-quality buildings and who are moving or who have recently moved into larger spaces. Within seconds, CrosTrac provides the client with a list of prospective firms most likely to need new or additional economy furniture. Before the furniture vendor contacts these prospects, the vendor can learn more about the prospects by using the web home page addresses of the prospects that are stored in CrosTrac and CrosTrac's ability to call up those web pages.

Interactive Advertising. In 1997, the Company began to derive significant revenue from the advertising of office and industrial real estate buildings for sale or lease on its software products. In the past, few effective vehicles for targeted marketing of office and industrial properties existed. For owners and agents representing buildings for lease or sale, reaching potential tenants directly was not effective because the tenants generally deferred to their commercial real estate broker to create the short lists of properties for them to consider. Brokers were difficult to reach with traditional marketing tools like advertising and direct mail, advertising was hindered because brokers did not rely on any single information source when researching properties for their clients, and direct mail also had limited effectiveness because brokers were deluged with marketing material.

Computerized information systems such as the Company's array of software products have significantly diminished the Company's clients' reliance on printed directories and materials. The Company introduced Interactive Advertising for its CoStar system as well as its web site to take advantage of this new trend toward electronic delivery and analysis of information. The Company's clients are made up in large part of commercial real estate professionals, who are normally the targeted market for advertisers. Since these professionals generally use the Company's products regularly, advertisers are realizing an opportunity to market in a more targeted fashion than previously possible. The multimedia aspects of the Company's products and web site permit multiple images, text and relevant information about a property for sale or lease to be delivered instantly to the user.

Each time a user performs a search, looks up a building, views a photograph or completes another task on one of the Company's products, a new interactive advertisement appears on a portion of the screen. If interested, the user can directly access further information on the property from the Company's Database. Full screen ads contain any combination of information, created and enhanced by professionally designed graphics. This includes floor plans, maps, photos, aerials or illustrations. On average, the Company believes an advertisement appears on one of its software products approximately 20 times per month. Interactive ads also appear on the Company's web site.

Jamison Reports. In connection with this Offering, the Company will acquire Jamison, a commercial real estate information provider based in Atlanta and Dallas/Fort Worth. Jamison has derived a substantial portion of its revenue from quarterly market conditions reports. The Company will create a new division, Jamison Reports, to expand this business to the Company's markets nationwide. This new division will be built upon Jamison's professionally trained analysts using the Company's Database to produce reports to help clients better understand the risks and opportunities inherent in real estate projects. Management believes Jamison Reports will provide institutional investors, Wall Street analysts and participants in the real estate market with consistent, independent analysis of real estate trends in each of the Company's markets.

Jamison Reports will be initially divided into two business groups: the Market Conditions Reporting Group and the REIT Reporting and Analysis Group. The Market Conditions Reporting Group currently publishes 80 quarterly and semiannual market conditions reports for the office, industrial, and

32

retail markets in Atlanta and the Dallas/Fort Worth markets. These reports are nationally recognized and include vacancy, absorption, effective rental forecasts, tenant profiles, and historical trends. The objective of this Group will be to expand the production of these same types of reports into all major U.S. commercial real estate markets. The REIT Reporting and Analysis Group intends to provide customized market reports to REITs and report on local and regional market trends potentially impacting a REIT's financial performance directly to Wall Street. The objective of the REIT Group is to provide access to market data to enable professional investors to value real estate with the support of systematic and comprehensive market data.

CLIENTS

Real estate brokers currently comprise a significant portion of the Company's clients and are the most active users of the Database. Other participants in the commercial real estate industry also require various subsets of the building-specific information found in the Database. Owners and investors are a significant and growing portion of the Company's client base and include institutions, banks, mortgage lenders, REITs, asset managers, investment banks and securities analysts. Another large and growing type of client is providers of goods and services to buildings and tenants such as property managers, developers, construction firms, architects, appraisers, building services vendors, tenant services vendors, telecommunication providers, office furniture vendors, space planners, insurance companies, utilities and moving companies. Public service agencies at the federal state and local level are also among the Company's clients, such as economic development agencies, the Federal Reserve, General Services Administration and Department of Commerce.

The Combined Company has over 1,900 clients, including leaders of the commercial real estate industry such as CB Commercial Real Estate Group, Inc., Merrill Lynch & Co., Julien J. Studley, Inc. and LaSalle Partners, Inc. Many of these national companies have multi-year, multi-market contracts with the Company. These multi-market contracts strengthen the Company's role within the industry and ease the Company's entry into new markets by providing an initial client base. In many instances, the Company's entry into new markets has been facilitated by demand from these leaders of the commercial real estate industry. No one client accounts for more than 5% of the Company's revenue and during the past five years, the Company's contract renewal rate has exceeded 90%.

SALES AND MARKETING

The Company sells its products through its own sales force, which is located at its Bethesda headquarters and at regional offices in each of the metropolitan areas in which the Company offers its products. All sales personnel have experience in the commercial real estate industry, so that they are able to position and employ the Company's products to create maximum value for each client's unique situation.

The Company has developed a multi-faceted marketing strategy that takes full advantage of the Database to effectively target its direct mail, advertising, trade show and public relations efforts. The Company uses the Database to identify and target the industry leaders in each of the markets it enters. The Company then builds upon this initial base through direct mailings, public relations and print advertising.

The Company has developed sales and marketing methods that achieve meaningful penetration in a new market within three months of entry. The Company has two specialized teams within its sales organization. The first is the National Sales Group, which places experienced account executives in new markets to make the first introductions. The second is a centralized Outbound Telemarketing Group, which has allowed the Company to leverage the time and experience of veteran senior-level sales people at a far lower cost than the incremental addition of new sales people. These sales resources also enable the Company to respond rapidly to competitive shifts in the marketplace, as their focus can quickly be shifted to different geographic areas or products as needed.

33

The Company has won several national awards over the last two years as a result of its in-house Marketing Group. The Company was the National Association of Industrial and Office Properties ("NAIOP") 1996 winner "Best Single Ad to Promote a Company," the 1997 1st Place winner "Ad Campaign to Promote a Company" for New York CoStar and the 1998 1st Place & Grand Award winner "Electronic Marketing" for the Company's web site. The Company's web site has received numerous awards including the NAIOP 1997 Grand Award in Electronic Marketing, the National Real Estate Investor/Internet Review Online Site of the Week, PikeNet 5-Star Superior Site Award, and the Web Marketing Association's Standard of Excellence Web Award.

As part of its marketing strategy, the Company seeks to make its products integral to its clients' transaction decision support processes. Therefore, unlike services that charge fees based in whole or in part on actual system usage time, the Company charges fixed monthly amounts which vary among clients based on the number of sites, organization size and number of accessible databases and other services to which a client subscribes. The Company believes this pricing policy encourages clients to use the Company's products regularly. Although the Company's subscription charges are quoted to clients in annual amounts, revenue is recognized on a monthly basis.

The basic CoStar contract consists of: (i) database including fundamental property and space availability data; (ii) local commercial real estate news and basic market statistics; (iii) basic application package with research and analytical capabilities; and (iv) client support and training. Additional components, such as additional data classes (office or industrial), other geographic areas, tenant information, and image databases, are available at additional cost. Over 80% of existing clients of the Company subscribe to additional components, the most popular of which are image databases and additional data classes.

COMPETITION

The market for information systems and services generally is competitive and rapidly changing. In the real estate industry, the principal competitive factors are the quality and depth of the underlying databases, the proprietary nature of methodologies, databases and technical resources, the usefulness of the data and reports generated by the software, client service and support, compatibility with the client's existing information systems, potential for product enhancement, vendor reputation, price and the effectiveness of marketing and sales efforts.

The Company has been in competition for many years with Black's Guide in Washington, Northern New Jersey and Los Angeles. Black's Guide primarily provides information through the print media but has periodically attempted to develop computer-delivered products and services competitive with those of the Company. In July 1996, Black's Guide, previously owned by McGraw-Hill Company and then by a group including CDA Technologies and Thompson Publishing Company, or their affiliates, was sold to Teleres, a joint venture between Dow Jones & Company, Inc. and Aegon (a Dutch insurance company). That joint venture targeted the investment and financial analyst community, through a product called "Teleres-Pro," that targeted primarily portfolio managers, and secondarily brokers and appraisers. In August 1997, the joint venture terminated, discharged its employees and returned Black's database to Black's Guide. In November 1997, Black's Guide reportedly entered into an arrangement, the terms of which are not known to the Company, with ReLocate, Inc. ReLocate, Inc. provides a database product that competes with the Company's product in New York City, Philadelphia and Boston. Further competition may result from that venture. Other competitors include: Smith's Guide and ILS in Orange County and the Association of Industrial Realtors in Los Angeles, CA; Loopnet Venture, Inc. which provides an Internet based listing service; and Leasetrends, a firm specializing in tenant information for Midwestern markets, Denver and South Florida. In addition, there are a number of firms with which the Company expects to compete as it expands into their areas. Other ventures may develop from which the Company will face competition.

While the Company faces competitors in individual markets, the Company believes that it does not presently face competition from any Company on a national basis. The Company has successfully competed with companies having greater financial, product development, technical and marketing resources than the Company with which to develop competitive databases, software and systems and other similar

34

competitors may arise in the future. The Company faces significant indirect competition from internal information services at some office and industrial brokerage firms, many of which developed their own databases. As the market for support systems develops, additional competitors may enter the market and competition may intensify. While the Company believes that it has successfully differentiated itself from competitors, there can be no assurance that future competition would not have a material adverse effect on the Company.

PROPRIETARY RIGHTS

The Company depends upon a combination of trade secret and copyright laws, nondisclosure and other contractual provisions and technical measures to protect its proprietary rights in its methodologies, Database and software. The Company has not filed any patent applications covering its methodologies and software. The Company distributes its software products under agreements that grant clients non-exclusive licenses and contain terms and conditions restricting the disclosure and use of its Database or software and prohibiting the unauthorized reproduction or transfer of its products. The products also include technical measures to prevent unauthorized copying. In addition, the Company attempts to protect the secrecy of its proprietary Database and other trade secrets and proprietary information through agreements with employees and consultants.

The Company also seeks to protect the source code of its software and its Database as trade secrets and under copyright law. Although copyright registration is not a pre-requisite for copyright protection, the Company has copyright registrations for certain of its software, user manuals and, portions of its Database. While the arrangement and selection of data are protectible, the actual data may not be, and others may be free to create databases that perform the same function. The Company believes, however, that the creation of competing databases would be very time-consuming and costly.

The Company has filed applications for the "CoStar" and "CrosTrac" marks in the United States and Canada and expects examination of such marks in due course. The Company believes that it has developed substantial goodwill in connection with these marks as an indicator of quality products and services.

The Company believes that, aside from the various legal protections of its proprietary information and technologies, factors such as the technological and creative skills of its personnel and its ongoing reliable product maintenance and support are integral to establishing and maintaining its leadership position within the real estate industry due to the rapid pace of innovation within the software industry.

EMPLOYEES

As of March 31, 1998, the Company employed a total of 145 full-time employees. Upon consummation of the acquisition of Jamison, the Company will employ approximately 190 full-time employees, including 133 researchers and 30 sales and marketing employees. None of the Company's employees is represented by a labor union. The Company has experienced no work stoppages and believes that its employee relations are excellent.

In addition to its corporate offices, the Combined Company leases office space in the following cities: New York; Los Angeles; Elmhurst, Illinois; San Francisco; Boston; Newport Beach; Philadelphia; Atlanta; and Dallas.

Options granted under the Stock Option Plan may be incentive or non-qualified stock options. The exercise price for a stock option may not be less than the fair market value of the Company's Common Stock on the date of grant. Stock options granted under the Stock Option Plan may not be transferred other than by will or by the laws of descent and distribution. Upon the occurrence of a Change of Control, as defined in the Stock Option Plan, all outstanding unexercisable options under the Stock Option Plan immediately become exercisable.

CERTAIN TRANSACTIONS

There have been no assets sold to or acquired from the Company and its officers or directors other than in connection with: (i) the acquisition of the Company's Chicago operations, (ii) routine compensation arrangements approved by the Board of Directors, (iii) subscriptions for additional equity to fund the Company's growth (iv) loans extended to the Company by certain of its stockholders from time to time, (v) the Jamison Acquisition from Henry D. Jamison, IV and Leslie Lees Jamison, and (vi) the RIG Contribution Agreement.

Warren H. Haber is chairman and chief executive officer of Founders Equity, Inc. ("Founders") and a director of the Company. On May 15, 1995, Founders/RIG, LLC ("FR LLC"), an affiliate of Founders acquired 296,652 limited partnership units of RIGLP for an aggregate purchase price of $3.1 million, or $10.45 per unit (equivalent to 923,478 shares of Common Stock of the Company at an effective price per share of $3.36). As part of the contractual arrangements that accompanied Founders' investment, Mr. Haber became a director and the Company agreed to register the securities FR LLC received for resale upon its demand at a future date. On December 3, 1996, FR LLC and certain of its affiliates acquired an additional 85,650.62 limited partnership units of RIGLP for an aggregate purchase price of $1.06 million, or $12.37 per unit (equivalent to 266,630 shares of Common Stock of the Company at an effective price per share of $3.97). In addition, pursuant to the RIG Contribution Agreement, FR LLC's registration rights were amended. See "Description of Capital Stock -- Registration Rights." FR LLC's right to designate a director of RIGINC will terminate upon consummation of the Transaction.

At the time of the Founders' investment in RIGINC and RIGLP in May 1995, those entities were indebted to Michael R. Klein, then and now the Chairman of the Company and a 31.8% stockholder, for loans he had extended with a then balance of $751,961. In connection with Founders' investment, $426,693 was repaid and the remaining balance of $325,268 was converted into 31,126 units of RIGLP (96,895 shares of Common Stock of the Company at an effective price per share of $3.36, the same price at which FR LLC purchased its interest in that transaction). In connection with that same transaction, the Company agreed to pay monthly fees to Founders of $10,000 and to Mr. Klein of $6,667, both of which will terminate in June 1998. During 1997, Mr. Klein committed to extend up to $1.0 million of credit to RIGINC, which in turn agreed to loan such amounts to RIGLP to support a $1.0 million credit facility RIGLP secured with Silicon Valley Bank ("SVB"), of which $650,000 has been extended and is outstanding. The RIGINC loan to RIGLP is contractually subordinated, and Mr. Klein's loans to RIGINC are structurally subordinated, to the SVB loan, interest on the balance is payable to RIGINC and Mr. Klein at the same rate (2% over prime) as the SVB loan and no principal may be repaid until the SVB loan is paid. Repayment of the SVB loan and the RIGINC/Klein loan are contemplated uses of the proceeds of this Offering. See "Use of Proceeds." As consideration for Mr. Klein's commitment, a committee of three independent directors authorized the issuance to Mr. Klein of warrants to purchase 15,000 units of RIGLP (effectively, 46,695 shares of the Company's Common Stock) at a price 10% less than the price at which the shares are being offered hereby, exercisable during the two years following the closing of this Offering. The Company has paid fees to the law firm of which Mr. Klein is a partner for legal services rendered; under the policies of his firm, Mr. Klein is not the partner responsible for supervising or billing for those services.

John Simon is a managing director of Allen and a director of the Company. On December 3, 1996, RIG Holdings, LLC ("RH LLC"), acquired 234,451.42 limited partnership units of RIGLP for an aggregate purchase price of $2.9 million, or $12.37 per unit (equivalent to 729,847 shares of Common Stock of the Company at an effective price per share of $3.97). RH LLC was granted the right to designate one member of the board of directors of RIGINC as well as certain registration rights in regards to the units it purchased. Pursuant to the RIG Contribution Agreement, RH LLC's registration rights were amended. See "Description of Capital Stock -- Registration Rights." Allen is the Member-Manager of RH LLC and, together with certain of its officers and affiliates, is the owner of approximately 26% of RH LLC; as Member-Manager, Allen is currently entitled to exercise voting power over all of the limited partnership units of RIGLP held by RH LLC. For these reasons, RH LLC may be deemed to be an affiliate of Allen. RH LLC's (and its members') right to designate a director of RIGINC will terminate upon consummation of the Transaction, at which time RH LLC will be dissolved and its ownership interests (and the registration rights connected therewith) will be distributed pro rata to its members. At

43

such time, Allen, together with certain of its officers and affiliates, will be the beneficial owner of 188,754 shares of Company's Common Stock. Allen, as a Representative, will receive certain underwriting discounts and commissions with respect to services rendered on behalf of the Company with respect to the Offering. See "Underwriting." Prior to making this investment, on November 5, 1996, Allen had loaned RIGLP $250,000, bearing interest at a rate of 8.5% per year. This loan was paid off in connection with RH LLC's investment.

Lanning Macfarland III is head of real estate publications at Law Bulletin Publishing Company ("LBPC") and a director of the Company. On March 29, 1996, RIGLP acquired all of the assets of ReSource from LBPC for 114,640.55 limited partnership units of RIGLP valued nominally at $10.45 per unit (equivalent to 356,876 shares of Common Stock of the Company at an effective price per share of $3.36). ReSource was a real estate information provider in the Chicago, Illinois area. On December 3, 1996, LBPC and certain of its affiliates acquired an additional 23,283.45 limited partnership units of RIGLP for an aggregate purchase price of $288,000, or $12.37 per unit (equivalent to 72,481 shares of Common Stock of the Company at an effective price per share of $3.97). In addition, pursuant to the RIG Contribution Agreement, LBPC's registration rights were amended. See "Description of Capital Stock -- Registration Rights." LBPC's right to designate a director of RIGINC will terminate upon consummation of the Transaction.

On February 17, 1998, the Company entered into the Jamison Contribution Agreement pursuant to which the Company agreed to acquire Jamison from Henry D. Jamison, IV and Leslie Lees Jamison for Company Common Stock valued at $10.0 million at the price per share of the Common Stock sold in this Offering. Consummation of the Jamison Contribution Agreement is contingent upon a number of factors, including completion of this Offering and consummation of the RIG Contribution Agreement. In connection with the consummation of the Jamison Contribution Agreement, Henry D. Jamison entered into an employment agreement with the Company to serve as an officer of the Company. This employment agreement will take effect upon consummation of the Jamison Acquisition. See "Management -- Employment Agreements." The Jamison Contribution Agreement includes terms such as: (i) usual and customary representations and warranties from the Jamison Selling Stockholders to the Company; (ii) usual and customary representations and warranties from the Company to the Jamison Selling Stockholders; (iii) survival of most representations and warranties for one year following the closing; (iv) an agreement by the Jamison Selling Stockholders not to compete with the Company for a period of two years following the closing; and
(v) indemnification by the Company and Jamison Selling Stockholders for breaches of their representations, warranties and covenants.

Effective as of March 5, 1998, all of the limited and general partners of RIGLP and all of the stockholders of RIGINC entered into the RIG Contribution Agreement. Pursuant to this agreement, each limited partner of RIGLP (other than RIGINC) agreed to contribute all of its limited partnership units to the Company, and all of the stockholders of RIGINC agreed to contribute all of their shares of RIGINC to the Company, all in exchange for 3.113 shares of Common Stock of the Company for each limited partnership unit or share of common stock. Consummation of the RIG Contribution Agreement is contingent upon a number of events, including completion of the Offering and consummation of the Jamison Contribution Agreement. All of the current officers and directors of the Company who will own shares of Common Stock after the Offering will exchange their units of RIGLP and their shares of RIGINC for Company Common Stock pursuant to the RIG Contribution Agreement.

DESCRIPTION OF CAPITAL STOCK

Immediately following the closing of the Offering, the authorized capital stock of the Company will consist of 30,000,000 shares of Common Stock, par value $.01 per share, and 2,000,000 shares of Preferred Stock, par value $.01 per share.

COMMON STOCK

The Company is authorized to issue 30,000,000 shares of Common Stock. As of February 28, 1998, the Company had no outstanding shares of Common Stock. Following the consummation of the Jamison Contribution Agreement and the RIG Contribution Agreement, the Company expects to have outstand-

44

ing 6,820,726 shares of Common Stock held of record by a total of 40 holders (assuming dissolution of RH LLC concurrent with the Offering). Upon the consummation of the Offering made hereby, there will be 8,929,817 shares of Common Stock outstanding, after giving effect to the sale of the shares of Common Stock offered hereby. Each stockholder of record is entitled to one vote for each outstanding share of Common Stock owned by him on every matter properly submitted to the stockholders for their vote. The holders of Common Stock are entitled to receive ratably such dividends as are declared by the Board of Directors out of funds legally available therefor. In the event of a liquidation, dissolution or winding up of the Company, holders of Common Stock have the right to a ratable portion of assets remaining after payment of liabilities. Holders of Common Stock have neither preemptive rights nor rights to convert their Common Stock into any other securities and are not subject to future calls or assessments by the Company. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are, and the shares offered hereby upon issuance and sale will be, fully paid and non-assessable.

PREFERRED STOCK

The Company is authorized to issue 2,000,000 shares of Preferred Stock in one or more series. As of February 28, 1998, the Company had no outstanding shares of Preferred Stock. The rights, preferences, privileges and restrictions, including dividend rights, voting rights, terms of redemption, retirement, sinking fund provisions, liquidation preferences, conversion rights and exchange rights, if any, of the Preferred Stock of each series will be fixed or designated pursuant to Articles Supplementary adopted by the Board of Directors or a duly authorized committee thereof.

REGISTRATION RIGHTS

The Company has granted certain registration rights to certain stockholders of the Company who will own in the aggregate 2,659,700 shares of Common Stock upon consummation of this Offering. Those holders have "piggyback" registration rights to request that the Company register any of their shares in the event that the Company proposes to register any of its securities under the Securities Act (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 of the Securities and Exchange Commission is applicable). However, if such piggyback rights are exercised in connection with an underwritten public offering of the Company's Common Stock, the managing underwriter of such an offering has the right to exclude or otherwise limit the number of such shares to be included in such public offering. Additionally, FR LLC and RH LLC and their successors share two "demand" registration rights to require the Company to prepare and file a registration statement so as to permit a public offering and sale of their shares of Common Stock, provided that at least 20% of the shares covered by the registration rights demand such registration. Likewise, the Jamison Selling Stockholders have one "demand" registration right to have the Company prepare and file a registration statement so as to permit a public offering and sale of their shares of Common Stock. None of the demand registration rights are exercisable until the date that is six months after the Offering.

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS

Section 203 of Delaware General Corporation Law. Section 203 of the Delaware General Corporation Law ("DGCL") prohibits certain transactions between a Delaware corporation and an "interested stockholder," which is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision prohibits certain business combinations (defined broadly to include mergers, consolidations, sales or other dispositions of such assets having an aggregate value in excess of 10% of the consolidated assets of the corporation, and certain transactions that would increase the interested stockholder's proportionate share ownership in the corporation) between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder, unless (i) the business combination is approved by the corporation's board of directors prior to the date the interested stockholder becomes an interested stockholder, (ii) the interested stockholder acquired at least 85% of the voting stock of the corporation (other than stock held by directors

45

who are also officers or by certain employee stock plan) in the transaction in which it becomes an interested stockholder or (iii) the business combination is approved by a majority of the board of directors and by the affirmative vote of 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

Certain Antitakeover Provisions. The Company's Certificate of Incorporation contains provisions that may have the effect of discouraging a third party from making an acquisition proposal for the Company. The Certificate of Incorporation of the Company, among other things, (i) permits the Board of Directors, but not the Company's stockholders, to fill vacancies and newly created directorships on the Board of Directors and (ii) provides that any action required or permitted to be taken by the stockholders of the Company must be effected at an annual or special meeting of stockholders and not by any consent in writing by such stockholders. Special meetings of stockholders may be called only by the Board of Directors. Such provisions would make the removal of incumbent directors more difficult and time-consuming and may have the effect of discouraging a tender offer or other takeover attempt not previously approved by the Board of Directors.

Indemnification and Limitation of Liability. The Company's Certificate of Incorporation provides that the Company shall, subject to certain limitations, indemnify its directors and officers against expenses (including attorneys' fees, judgments, fines and certain settlements) actually and reasonably incurred by them in connection with any suit or proceeding to which they are a party so long as they acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to a criminal action or proceeding, so long as they had no reasonable cause to believe their conduct to have been unlawful.

Section 102 of the DGCL permits a Delaware corporation to include in its certificate of incorporation a provision eliminating or limiting a director's liability to a corporation or its stockholders for monetary damages for breaches of fiduciary duty. DGCL Section 102 provides, however, that liability for breaches of the duty of loyalty, acts or omissions not in good faith or involving intentional misconduct, or knowing violation of the law, and the unlawful purchase or redemption of stock or payment of unlawful dividends or the receipt of improper personal benefits cannot be eliminated or limited in this manner. The Company's Certificate of Incorporation includes a provision which eliminates, to the fullest extent permitted, director liability for monetary damages for breaches of fiduciary duty.

Preferred Stock. Upon the completion of the Offering, the Company will have the authority to issue up to 2,000,000 shares of so-called "blank-check" preferred stock which authorizes the Board of Directors to establish one or more series of Preferred Stock and to fix and determine the relative rights, preferences and limitations of each class or series of Preferred Stock with voting and conversion rights which could adversely affect the voting power of the holders of Common Stock and have the effect of delaying or preventing a change of control of the Company. After the completion of the Offering, no shares of Preferred Stock will be outstanding. The Company has no current intention to issue any shares of Preferred Stock.

TRANSFER AGENT AND REGISTRAR

Upon consummation of the Offering, the transfer agent and registrar for the Common Stock will be American Stock Transfer & Trust Company.

SHARES ELIGIBLE FOR FUTURE SALE

Upon the completion of the Offering, the Company will have 8,929,817 outstanding shares of Common Stock. Of these shares, the 2,700,000 shares of Common Stock sold in this Offering will be freely tradable without restriction or further registration under the Securities Act unless purchased by affiliates of the Company (as defined under the Securities Act). 6,229,817 shares that will be held by existing stockholders, representing approximately 70% of the total number of shares of Common Stock to be outstanding upon the completion of this Offering, may not be resold except pursuant to an effective registration statement filed by the Company or an applicable exemption from registration, including an exemption under Rule 144. 318,182 of these shares are subject to contractual pledge or lock-up obliga-

46

tions to the Company. In addition, certain holders of Common Stock have agreed that they will not, without obtaining the prior written approval of the Representatives (as defined in "Underwriting"), directly or indirectly offer for sale, sell, transfer, encumber, contract to sell, grant any option, right or warrant to purchase or otherwise dispose (or announce any offer, sale, transfer, encumbrance, contract to sell, grant of an option to purchase or other disposition) of any shares of Common Stock, or any securities, subject to certain exceptions, convertible into, or exchangeable or exercisable for, shares of Common Stock, for a lock-up period of 240 days after the effective date of the Registration Statement of which this Prospectus forms a part. See "Underwriting."

In general, under Rule 144 as currently in effect, a person (or persons whose shares are aggregated), including an affiliate of the Company (as defined in Rule 144, an "Affiliate"), who has beneficially owned "restricted securities" (as that term is defined in Rule 144) for a period of at least one year from the later of the date such restricted securities were acquired from the Company or the date they were acquired from an Affiliate, is entitled to sell, within any three-month period, a number of such securities that does not exceed the greater of (i) 1% of the then outstanding shares of the Company's Common Stock (approximately 90,000 shares immediately after the Offering) or (ii) the average weekly trading volume in the Company's Common Stock during the four calendar weeks preceding the filing of notice of such sale. Sales under Rule 144 are also subject to certain restrictions on the manner of sale, notice requirements, and the availability of current public information about the Company. Under Rule
144(k), a person who is not deemed to have been an Affiliate of the Company at any time during the 90 days preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years (including the holding period of any prior owner except an affiliate), is entitled to sell such shares without complying with the manner of sale, notice, public information, or volume limitation provisions of Rule 144; therefore, unless otherwise restricted, "144(k) shares" may be sold immediately upon the completion of the Offering, subject to the lock-up periods described in the preceding paragraph.

Under Rule 701 under the Securities Act, certain shares issued pursuant to employee benefit plans or arrangements in effect prior to this Offering are eligible for resale 90 days after the Company becomes a reporting company under the Exchange Act and may be sold by persons other than Affiliates subject only to the manner of sale provisions of Rule 144 and by Affiliates without compliance with the holding period requirements of Rule 144.

As soon as practicable following the expiration of the lock-up periods described above, the Company intends to file a registration statement or statements on Form S-8 under the Securities Act to register the shares of Common Stock issuable pursuant to the Stock Option Plan. As of March 31, 1998, options for units of RIGLP and shares of RIGINC were outstanding that, when converted to options for shares of Common Stock under the Stock Option Plan, will result in options to purchase approximately 409,297 shares, of which options to purchase 256,128 shares will be exercisable. Shares issued upon the exercise of the options generally will be eligible for sale in the public market after the effective date of such registration, subject, in certain cases, to the lock-up agreements described herein and volume and other restrictions.

Prior to the Offering, there has been no public market for the Common Stock. No predictions can be made as to the effect, if any, that market sales of shares or the availability of shares for sale will have on the market price of the Common Stock prevailing from time to time. The Company is unable to estimate the number of shares that may be sold in the public market pursuant to Rule 144, since this will depend on the market price of the Common Stock, the specific circumstances of the sellers and other factors. Nevertheless, sales of significant amounts of the Common Stock of the Company in the public market could adversely affect the market price of the Company's Common Stock.

After the completion of the Offering, certain persons will be entitled to certain rights with respect to registration under the Securities Act of approximately 2,659,700 shares of Common Stock.

UNDERWRITING

The Underwriters named below (the "Underwriters"), through their representatives, Allen & Company Incorporated and Needham & Company, Inc. (the "Representatives"), have severally agreed, subject to the terms and conditions of the Underwriting Agreement, to purchase from the Company and the Jamison Selling Stockholders the number of shares of Common Stock set forth opposite their names below. The Underwriters are committed to purchase and pay for all such shares if any are purchased.

          NAME OF UNDERWRITER              NUMBER OF SHARES
---------------------------------------   -----------------
Allen & Company Incorporated ..........
Needham & Company, Inc. ...............
                                              ---------
 Total ................................       2,700,000
                                              =========

The Representatives have advised the Company that the Underwriters propose to offer the shares to the public at the offering price set forth on the cover page of this Prospectus and that the Underwriters may allow certain dealers who are members of the National Association of Securities Dealers, Inc. (the "NASD") concessions of not in excess of $ per share of Common Stock, of which not in excess of $ may be reallowed to other dealers who are members of the NASD. After the commencement of the Offering, the public offering price, concession and reallowance to dealers may be reduced by the Representatives. No such reduction shall change the amount of proceeds to be received by the Company as set forth on the cover page of this Prospectus.

In connection with the Offering and after the Offering, the Underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Stock. Specifically, the Underwriters may over allot the Offering, creating a syndicate short position. In addition, the Underwriters may bid for and purchase shares of Common Stock in the open market to stabilize the price of the Common Stock. These activities may stabilize, maintain or otherwise affect the market price of the Common Stock above independent market levels. The Underwriters are not required to engage in these activities and may end these activities at any time.

The Company has granted to the Underwriters the Over-Allotment Option, exercisable during the 45-day period after the closing date of the Offering, to purchase up to an aggregate of 270,000 additional shares of Common Stock at the initial public offering price, less underwriting discounts and commissions. The Underwriters may exercise such option only for the purpose of covering over-allotments made in connection with the sale of the Common Stock offered hereby.

As is customary for such arrangements, the Company has agreed to indemnify the Underwriters and each person who controls any Underwriter against certain liabilities in connection with the Registration Statement, such as liabilities under the Securities Act, including for material misstatements or omissions in the Registration Statement. In addition, the Underwriters have agreed to indemnify the Company for such liabilities arising from material misstatements or omissions in connection with disclosure for which the Underwriters are responsible. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the Underwriters, the Underwriters have been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The Company has agreed to reimburse the Representatives their out-of-pocket expenses incurred in connection with the Offering, which are estimated to be $150,000.

The foregoing discussion of the material terms and provisions of the Underwriting Agreement is qualified in its entirety by reference to the detailed provisions of the Underwriting Agreement, the form of which has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part.

48

The Company, certain of its officers and directors who own shares of Common Stock and certain other stockholders and option holders of the Company have executed agreements pursuant to which they have agreed not to offer, pledge, sell, contract to sell, grant any option for the sale of or otherwise dispose of any of the Company's securities held by them for a period of 240 days from the effective date of the Offering, without the prior written consent of Allen, subject to certain exceptions. See "Shares Eligible for Future Sale."

The Representatives have advised the Company that the Underwriters do not intend to confirm sales to any account over which they exercise discretionary authority.

Allen is the Manager-Member of RH LLC and, together with certain of its officers and affiliates, owns approximately 26% of RH LLC, which beneficially owns an aggregate of 234,451 units of RIGLP (effectively 729,847 shares of Common Stock of the Company). RH LLC will be dissolved concurrently with the consummation of the Offering. See "Certain Transactions" and "Principal Stockholders." John Simon, a managing director of Allen, may be deemed to be a beneficial owner of shares of Common Stock held by RH LLC or Allen and serves as a director of the Company.

Consistent with the rules of the NASD, of which Allen is a member, the Company may be deemed to be an affiliate of Allen, inasmuch as RH LLC (which will be dissolved in connection with the Offering) is the beneficial owner of more than 10% of the Company's Common Stock. The Offering is therefore being made in conformity with the applicable provisions of such rules, including Rule 2720 of the NASD Conduct Rules. Accordingly, the price of the Shares being offered hereby is no higher than that recommended by Needham as "qualified independent underwriter" as defined in the applicable provisions of the rules of the NASD; in connection with serving in such a capacity, Needham is assuming the responsibilities of acting as qualified independent underwriter in pricing the Offering and in exercising the usual standards of due diligence with respect thereto. As compensation for serving as a Representative, Needham will receive underwriting discounts and commissions as set forth on the front cover page of the Prospectus; Needham will not receive any additional compensation for serving as qualified independent underwriter.

Prior to the Offering, there has been no public market for the Common Stock. Consequently, the initial public offering price of the shares of Common Stock offered and sold in the Offering will be determined by negotiation among the Company and the Representatives and will not necessarily bear any relationship to the Company's book value, assets, past operating results, financial condition, or other established criteria of value. Factors to be considered in determining such price include the nature of the Company's business, its history and present state of development, an assessment of the Company's recent financial results and current financial condition, future prospects of the Company, the qualifications of the Company's management, the general condition of the securities markets at the time of the Offering, and other relevant factors.

LEGAL MATTERS

The validity of the Common Stock offered hereby will be passed upon for the Company by Wilmer, Cutler & Pickering, Washington, D.C. Mr. Klein is the Chairman of the Board of Directors of the Company and is a partner of Wilmer, Cutler & Pickering. After the Offering, Mr. Klein will be a 24.3% stockholder of the Company. See "Management," "Principal Stockholders" and "Certain Transactions." Certain legal matters in connection with the Offering will be passed upon for the Underwriters by Werbel & Carnelutti, a Professional Corporation, New York, New York.

EXPERTS

INTRODUCTION TO UNAUDITED PRO FORMA

CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial statements give effect to (i) the contribution to Realty Information Group, Inc. (the "Company") by the holders of units of Realty Information Group, L.P. ("RIGLP") and the stockholders of OLD RIG, Inc. ("RIGINC") of all of the units of RIGLP (other than units held by RIGINC) and the capital stock of RIGINC in return for certain shares of Common Stock of the Company, (ii) the acquisition of Jamison Research, Inc. ("Jamison"), and (iii) the Company's planned initial public offering of 2,700,000 shares of Common Stock. The acquisition of Jamison will occur simultaneously with the closing of the Company's initial public offering and will be accounted for using the purchase method of accounting.

The unaudited pro forma condensed combined balance sheet gives effect to the formation of the Company and the acquisition of Jamison as if they had occurred on March 31, 1998. The unaudited pro forma condensed combined statement of operations gives effect to the transactions as if they had occurred on January 1, 1997.

Unless otherwise specified, the information in the unaudited pro forma condensed combined financial statements (a) assumes that the Underwriters' Over-Allotment Option is not exercised, (b) gives effect to the contribution to the Company of all of the outstanding equity interests in its predecessors in exchange for the Company's shares at a rate of 3.113 shares of Company Common Stock for each unit of RIGLP and share of RIGINC.

The pro forma adjustments are based on estimates, available information and certain assumptions and may be revised as additional information becomes available. The pro forma financial data do not necessarily represent what the Company's financial position or results of operations would actually have been if such transactions in fact had occurred on those dates or the results of operations for any future period. The unaudited pro forma combined financial statements should be read in conjunction with Management's Discussion and Analysis and the other financial statements and notes thereto included elsewhere in this Prospectus.

NOTES TO UNAUDITED PRO FORMA
CONDENSED COMBINED FINANCIAL STATEMENTS

1. GENERAL

The Company was formed in February 1998 to succeed its predecessors, RIGLP and RIGINC, and to acquire Jamison in connection with an initial public offering of its common stock. The predecessors, RIGLP and RIGINC, will be combined on a historical cost basis with the Company as an exchange of interests of entities under common control. The acquisition of Jamison will occur simultaneously with the completion of the Company's initial public offering and will be accounted for using the purchase method of accounting.

The Company will consummate a series of related transactions in connection with the Offering. Pursuant to a Contribution Agreement effective March 5, 1998 (the "RIG Contribution Agreement"), RIGLP and RIGINC will be consolidated with the Company. Limited partners of RIGLP (other than RIGINC) and all of the stockholders of RIGINC will receive 3.113 shares of the Common Stock of the Company per each limited partnership unit or share of common stock exchanged. See "Certain Transactions." As a result, the Company will own (directly or indirectly) all of the capital stock of RIGINC and all of the equity of RIGLP.

Pursuant to a Contribution Agreement dated February 17, 1998 (the "Jamison Contribution Agreement"), Jamison will be consolidated with the Company in a transaction in which the stockholders of Jamison will contribute all of the outstanding capital stock of Jamison to the Company in exchange for $10 million of the Common Stock of the Company, valued at the price at which Common Stock is sold in this Offering. As provided in the Jamison Contribution Agreement, the Company will offer for resale by the Jamison Selling Stockholders as part of this Offering up to 65% of the shares of the Common Stock issued to them pursuant to the Jamison Contribution Agreement.

The historical financial statements included in the unaudited pro forma condensed combined balance sheet and statement of operations were derived from the separate financial statements of the Company, RIGINC (including its consolidated subsidiary, RIGLP) and Jamison as of December 31, 1997 and March 31, 1998 and for the year and the three months then ended. The related audited and unaudited historical financial statements are included elsewhere herein and should be read in conjunction with these pro forma condensed combined financial statements.

2. ACQUISITION OF JAMISON

The Company will adjust the carrying value of the acquired assets and liabilities of Jamison to fair market value as discussed below. The amounts and classifications are estimates, based on the current operations of Jamison, and the recorded book values of assets and liabilities at March 31, 1998. The allocation will include all existing recorded assets and liabilities of Jamison which currently approximate fair market value except for capitalized product development costs. These accounts are not shown here because they have no significant net book value.

                                                    ESTIMATED VALUE     ESTIMATED LIFE
                                                   -----------------   ---------------
Capitalized product development ................      $ 2,500,000      2-5 years
In process research and development ............        3,000,000
Intangible assets (customer base, in place work-
 force, and goodwill) ..........................        4,500,000      7-15 years
                                                      -----------
                                                      $10,000,000
                                                      ===========

Capitalized product development includes those developed software products and proprietary databases which are expected to produce revenues currently, until their conversion by the Company into products with a format consistent with the Company's products. This effort is expected to take up to 2 years. Certain underlying data elements of the Jamison products are expected to continue in use. These elements have a 5 year life.

F-5

REALTY INFORMATION GROUP, INC.
NOTES TO UNAUDITED PRO FORMA
CONDENSED COMBINED FINANCIAL STATEMENTS- (CONTINUED )

In process research and development includes certain unique products which are sold by Jamison in the Atlanta and Dallas regions and are expected to be further developed for use by the Company in all its covered regions. This development effort is expected to require significant funds and take up to two years to complete. As a result, the Company considers this technology in process and will take a one time charge to earnings for the $3,000,000 assigned to the acquired value of this technology in the period following completion of the acquisition.

Certain intangible assets have been identified within the business and are expected to have substantial value to the Company and have been assigned a portion of the purchase price based on their estimated fair market value. The remaining purchase price, estimated at approximately $2,000,000, is allocated to goodwill.

3. PRO FORMA ADUSTMENTS

The pro forma adjustments reflect the consolidation of the Company and its predecessors and the acquisition of Jamison. The offering adjustments reflect the issuance of common stock of the Company and the net proceeds from the initial public offering. The adjustments are as follows:

Pro forma condensed combined statement of operations:

(a) Estimated charges for amortization of the assets noted above, amounting to $1,100,000 and $275,000 to cost of sales for product amortization and $400,000 and $100,000 to operating expenses for amortization of other assets for the year ended December 31, 1997 and the three months ended March 31, 1998, respectively.

(b) A charge of $50,000 for financing costs is recorded to recognize 46,695 warrants issued in connection with the subordinated debt of the Company. Such warrants are exerciseable at 10% below the price of the stock in an initial public offering. This charge is offset by the net reduction of $26,000 in interest expense of RIGLP due to the planned repayment of debt from offering proceeds. This results in a net charge of $24,000 for the year ended December 31, 1997. The reduction in interest expense for the three months ended March 31, 1998 is $43,550.

(c) Minority interest-net loss allocated to limited partners of RIGLP recorded in the accounts of RIGINC is eliminated.

Pro forma condensed combined balance sheet:

(d) Minority interest -- RIGLP limited partners' equity recorded in the accounts of RIGINC is eliminated.

(e) The estimated purchase price of $10,000,000 is allocated to capitalized product development and intangible assets as indicated in Note 2.

F-6

Offering adjustment:

(f) Assuming an initial public offering price of $11.00 per share, the proceeds of the initial public offering amounting to approximately $20,600,000, net of expenses of the offering estimated at $950,000, are used initially to eliminate debts of RIGLP, RIGINC and Jamison, including the line of credit, subordinated debt to partner, advances from stockholders, and long term debt. The total elimination of debt is estimated at $1,789,420 in current debts and $31,382 in long term debt for a total of $1,820,802, resulting in an increase in cash of the Company from the Offering, after repayment of debt, of $18,779,198.

4. WEIGHTED AVERAGE SHARES OUTSTANDING

Includes 1,899,015 shares or units of the Company's predecessors converted at a rate of 3.113 shares per share of RIGINC or unit of RIGLP and the 909,091 shares issued to the Jamison stockholders in connection with the acquisition of Jamison, as if such shares were outstanding for the entire period. Stock options and warrants outstanding have been excluded from the calculation because their effect is anti-dilutive.

REALTY INFORMATION GROUP, INC.
NOTES TO BALANCE SHEET

1. ORGANIZATION

Realty Information Group, Inc. (the "Company") was formed in February 1998 to succeed its predecessors, Realty Information Group, L.P. ("RIGLP") and OLD RIG, Inc. ("RIGINC"), and to acquire Jamison Research, Inc. ("Jamison") in connection with an initial public offering of its common stock. The Company has not commenced operations, and all activities to date have related to its organization and the initial public offering. The Company is dependent upon the initial public offering to succeed its predecessor companies and execute the pending acquisition. Therefore, there is no assurance that the pending acquisition or related transactions will be completed.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 at the date of the financial statements and the associated amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates.

Unaudited Balance Sheet

The balance sheet as of March 31, 1998 is unaudited. In the opinion of management, such balance sheet reflects all adjustments necessary for a fair presentation.

3. PLANNED TRANSACTIONS

The Company has entered into the Agreement and Plan of Contribution with RIGINC, RIGLP, Jamison and the stockholders of Jamison (the "Agreement"), in which the various entities will contribute their stock or partnership units to the Company in exchange for a distribution of the common stock of the Company contingent upon the closing of the initial public offering. Pursuant to the Agreement, the Company intends to undertake an initial public offering of its common stock. In March, 1998, the Company filed a registration statement on Form S-1 for the initial public offering of its common stock. The offering costs will be netted against the proceeds of the offering. Simultaneously with and contingent upon the initial public offering, the Company will purchase Jamison at a price equal to $10 million in shares.

REALTY INFORMATION GROUP, L.P.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

Realty Information Group, L.P. ("RIGLP") has created a proprietary database (the "Database") of comprehensive office and industrial real estate information in seven major metropolitan areas throughout the United States. In addition, the Company has developed a portfolio of multimedia software products that allow clients to access the Database. The Database and software products are distributed to its clients under license agreements which are typically one to three years in duration.

Pursuant to the partnership agreement, the term of RIGLP will continue until December 31, 2094. Generally, the profits and losses of RIGLP will be allocated to the partners in proportion to their respective partnership percentages, which are generally based on contributions to RIGLP. There are certain limitations on the allocation of partnership losses such that any limited partner can not have a capital account deficit. The partnership agreement specifies that RIGLP shall have the option to require the initial limited partner to sell its partnership interest to RIGLP for fair value during the period from November 1, 2004 through November 30, 2004. Additionally, the agreement specifies that during this same period, the initial limited partner has the right to require RIGLP to repurchase its limited partnership interest for fair value.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements of RIGLP include the accounts of New Market Systems, Inc. ("NMS") acquired on March 1, 1997 (Note 3).

Unaudited Interim Statements

The consolidated financial statements as of March 31, 1998 and for the three months ended March 31, 1998 and 1997 are unaudited. In the opinion of management, such financial statements reflect all adjustments necessary for a fair presentation of the results of the respective interim periods. All such adjustments are of a normal recurring nature.

Reclassifications

Certain amounts in the 1995 and 1996 financial statements have been reclassified to conform with the 1997 presentation.

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 at the date of the financial statements and the associated amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates.

Revenue Recognition

Revenue from the sale of licenses to the proprietary software and the Database is recognized on a straight-line basis over the term of the license, which is typically from one to three years.

Cash and Cash Equivalents

RIGLP's cash and cash equivalents include highly liquid instruments purchased with an original maturity of less than three months.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

Property and Equipment

Property and equipment, including leasehold improvements, are stated at cost and depreciated using the straight-line method over estimated useful lives of three to seven years. Leasehold improvements are amortized over the lesser of the related lease term or the useful life.

Capitalized Product Development Costs

Initial costs to develop and produce the Database and software products, including direct labor, contractors and applicable overhead are capitalized from the time technological feasibility is determined until product release. Prior to technological feasibility, such costs are classified as software development and expensed as incurred. Amortization of capitalized costs is based on the greater of the amount computed using (a) the ratio of current gross revenues to the sum of current and anticipated gross revenues, or (b) the straight-line method over the remaining estimated economic life of the product, typically five years after product release. Included in amortization is approximately $75,000, $181,000, $287,000 and $112,000 of expense related to the capitalized product development costs for the years ended December 31, 1995, 1996 and 1997 and the three months ended March 31, 1998, respectively.

Intangible Assets

The value assigned to the customer base acquired through the purchase of NMS and Chicago Resource, Inc., and goodwill, resulting from the purchase of Space Datagraphics Systems, Inc., in December 1994, are being amortized on a straight-line basis over ten years. RIGLP continuously evaluates and adjusts, if necessary, the net realizable value of these assets.

Income Taxes

RIGLP is a partnership for federal income tax purposes under which income, losses, deductions and credits are allocated to and reported by the partners on their individual income tax returns. Accordingly, no provision for income tax has been recorded in the financial statements. Upon the effectiveness of the Registration Statement on Form S-1 (see note 10), the partnership will become part of Realty Information Group, Inc., the successor, and will be taxed as a C-Corporation. Had the Partnership operated as a C-Corporation for the year ended December 31, 1995, 1996 and 1997 and the three months ended March 31, 1998, their would be no income taxes recorded as a result of the losses for the periods. NMS is a corporation which provides for income taxes under the provisions of Statement of Financial Accounting Standards No. 109. As of December 31, 1997, NMS had net loss carryforwards of approximately $522,000. A valuation allowance has been established against the related net deferred tax asset in its entirety.

Unit Based Compensation

In October 1995, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation" which is effective for the RIGLP's financial statements after 1995. SFAS No. 123 allows companies to account for stock-based compensation under the provisions of either SFAS No. 123 or Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees", with pro forma disclosure as if the measurement provision of SFAS No. 123 had been adopted. RIGLP applies these principles and accounts for its unit based compensation in accordance with the provisions of APB No. 25. As such, the adoption of SFAS No. 123 does not impact the financial position or results of operations of RIGLP.

Advertising Costs

Advertising costs are expensed as incurred. Such costs included in selling and marketing expense totaled approximately $125,698, $203,659, $397,966 and $53,908 for the years ended December 31, 1995, 1996, and 1997 and the three months ended March 31, 1998, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

Concentration of Credit Risk

RIGLP performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral. RIGLP maintains reserves for credit losses, and such losses have been within management's expectations. The credit risk in accounts receivable is mitigated by the large and widespread customer base and lack of dependence on individual customers. The carrying amount of the accounts receivable approximates their net realizable value.

Recent Pronouncements

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Comprehensive Income", which is required to be adopted for the year ended December 31, 1998. SFAS 130 requires that an enterprise (a) classify items of other comprehensive income by their nature in the financial statements and (b) display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the Statements of Stockholders' Deficit. The implementation of SFAS 130, "Comprehensive Income", information on the financial statements is not expected to be material. For all periods presented, including the three months ended March 31, 1998, RIGLP had no items of comprehensive income and, accordingly, the Statement does not apply.

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related Information", which is required to be adopted for the year ended December 31, 1998. SFAS 131 changes the way public companies report segment information in annual financial statements and also requires those companies to report selected segment information in interim financial reports to stockholders. The disclosure for segment information on the financial statements is not expected to be material.

In October 1997, the AICPA issued SOP 97-2, Software Revenue Recognition, which changes the requirements for revenue recognition effective for transactions that the Company will enter into beginning January 1, 1998. The implementation of SOP 97-2 is not expected to have a material effect on the financial statements of RIGLP. As of January 1, 1998 the Company adopted AICPA SOP 97-2, Software Revenue Recognition, which was effective for transactions that RIGLP entered into in 1998. Prior years were not restated. The effect of adopting SOP 97-2 was not material in the financial statements of RIGLP. In March 1998, AcSEC issued SOP 98-4 which defers for one year the implementation of certain prevision of SOP 97-2. The issuance of SOP 98-4 had no effect on RIGLP.

Pro Forma Loss Per Share

Pro Forma per share information is presented as if the Partnership had operated as a C-Corpration for all perios presented. In February 1997, the Finacial Accounting Standards Board issued Statement No. 128, Earnings per Share. All pro forma earnings per share amounts for all periods have been presented to conform to the Statement 128 requirements.

3. ACQUISITIONS

On April 1, 1996, RIGLP expanded to the Chicago area by purchasing substantially all of the assets and liabilities of Chicago ReSource, Inc. ("CRI"), through the issuance of 114,640.55 partnership units valued at $1,200,000. On March 1, 1997 RIGLP expanded to the San Francisco area through a purchase of 99.3% of the outstanding shares of New Market Systems, Inc. ("NMS"), a California corporation, through the exchange of 14,710 partnership units valued at $206,000 and payment of $550,000 in cash. The accompanying statements of operations reflect the operating results of CRI and NMS since the effective date of the acquisition. Except for cash acquired, these transactions have been excluded from the statements of cash flows and have been accounted for using purchase accounting.

5. LINE OF CREDIT

In October, 1997, RIGLP entered into a $1,000,000 line of credit agreement with Silicon Valley East (a Division of Silicon Valley Bank). The line bears interest at the bank's prime rate plus 2%, and has a one year term. Borrowings under the line are secured by the assets of RIGLP. RIGLP is in compliance at December 31, 1997, with the terms of the line of credit agreement which includes covenants requiring minimum cash, working capital and partners' capital amounts, and limits operating losses of RIGLP. At December 31, 1997, $1,000,000 of borrowings were outstanding under the line. Interest paid in 1997 totaled $17,760.

6. RELATED PARTY TRANSACTIONS

During 1997, the general partner of RIGLP obtained a commitment from a partner for an additional $1,000,000 of subordinated, unsecured credit, bearing interest at a rate equal to that of the line of credit. In connection with the commitment, the individual contributing partner has received warrants for the purchase of 15,000 shares of stock of the general partner, exerciseable only in the event of an initial public offering or an equity funding in excess of $5.0 million ("a triggering event"). The warrants have a two year term beyond the triggering event and provide for the purchase of an equivalent number of shares at a price of 10% less than the price of the stock sold in an initial public offering or an equity funding in excess of $5.0 million. At December 31, 1997, $650,000 of borrowings were outstanding under the commitment and have been advanced to RIGLP. Interest paid in 1997 totaled $8,055.

Commencing in May 1995 RIGLP agreed to pay an investor $10,000 per month and the Chairman of RIGLP $6,667 per month for consulting services. During 1995, 1996 and 1997, RIGLP incurred fees of approximately $130,000, $200,000 and $200,000, respectively, related to such consulting services.

8. SALES OF PARTNERSHIP UNITS

During 1995 RIGLP sold 327,780 limited partnership units to two investors for total net proceeds of approximately $3.3 million. The transaction granted the investors liquidation preferences of the investment plus a 6% per annum return in the event of a liquidation. In addition, beginning April 15, 1999 through April 15, 2001, the transaction allows the investors to liquidate their investments under a range of alternative strategies and exit transactions. The proceeds of the transaction were used to retire a related party note payable and to fund RIGLP's working capital needs.

On December 3, 1996, RIGLP completed a private placement (the "Private Placement") in which RIGLP raised approximately $5.0 million through the sale of 338,580.2 partnership units. The proceeds of the transaction were used to fund RIGLP's working capital needs and the NMS acquisitions.

In May 1997, RIGLP issued 21,428 partnership units valued at $300,000 to provide compensation to an officer, $150,000 of which had been accrued at December 31, 1996.

Unit Option Plan

In March 1996 RIGLP adopted the 1996 Unit Option and Unit Purchase Plan (the "Plan"), under which 200,000 partnership units were reserved for issuance upon the exercise of options granted to officers, executive personnel, directors and key employees. Certain options previously granted were included in the Plan. The option plan is administered by the Board of Directors of RIGINC. Options are granted at prices which the Board of Directors of RIGINC believes approximate the fair market value of its limited partnership units. Individual grants become exercisable over a period of three years from the date of grant. The contractual term of the options range from three to ten years from the date of grant.

During 1996 RIGLP adopted the disclosure-only provisions of SFAS No. 123. Accordingly, no compensation cost has been recognized for the Plan. Had compensation expense related to the Plan been determined based on the fair value at the grant date for options granted in 1995, 1996 and 1997 consistent with the provisions of SFAS No. 123, RIGLP's pro forma net loss would have been $817,408, $2,690,009 and $3,337,420 as of December 31, 1995, 1996 and 1997, respectively. Such pro forma results are not representative of the effects on operations for future years.

The fair value of each option grant is estimated on the date of grant using the Minimum Value option-pricing model with the following weighted-average assumptions: dividend yield of 0%; risk-free interest rate of approximately 6.0%; and expected life of 3 years for 1995 grants and 4 years for 1996 and 1997 grants.

The following table summarizes information regarding unit options outstanding at December 31, 1997:

OLD RIG, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

OLD RIG, INC. ("RIGINC") is the majority owner of Realty Information Group, L.P. (RIGLP) and is its General Partner. RIGINC has no operations of its own. RIGLP has created a proprietary database (the "Database") of comprehensive office and industrial real estate information in seven major metropolitan areas throughout the United States. In addition, RIGLP has developed a portfolio of multimedia software products that allow clients to access the Database. The Database and software products are distributed to its clients under license agreements which are typically one to three years in duration.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements of RIGINC include the accounts of RIGLP and of New Market Systems, Inc.("NMS") acquired on March 1, 1997 (Note 3).

Unaudited Interim Statements

The consolidated financial statements as of March 31, 1998 and for the three months ended March 31, 1998 and 1997 are unaudited. In the opinion of management, such financial statements reflect all adjustments necessary for a fair presentation of the results of the respective interim periods. All such adjustments are of a normal recurring nature.

Reclassifications

Certain amounts in the 1995 and 1996 financial statements have been reclassified to conform with the 1997 presentation.

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 at the date of the financial statements and the associated amounts of revenues and expenses during the reporting period. Actual results could differ from the estimates.

Revenue Recognition

Revenue from the sale of licenses to the proprietary software and the Database is recognized on a straight-line basis over the term of the license, which is typically from one to three years.

Cash and Cash Equivalents

RIGINC's cash and cash equivalents include highly liquid instruments purchased with an original maturity of less than three months.

Property and Equipment

Property and equipment, including leasehold improvements, are stated at cost and depreciated using the straight-line method over estimated useful lives of three to seven years. Leasehold improvements are amortized over the lesser of the related lease term or the useful life.

Capitalized Product Development Costs

Initial costs to develop and produce the Database and software products, including direct labor, contractors and applicable overhead are capitalized from the time technological feasibility is determined until product release. Prior to technological feasibility, such costs are classified as software development and expensed as incurred. Amortization of capitalized costs is based on the greater of the amount computed using (a) the ratio of current gross revenues to the sum of current and anticipated gross

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

revenues, or (b) the straight-line method over the remaining estimated economic life of the product, typically five years after product release. Included in amortization is approximately $75,000, $181,000, $287,000 and $112,000 of expense related to the capitalized product development costs for the years ended December 31, 1995, 1996 and 1997, and the three months ended March 31, 1998, respectively.

Intangible Assets

The value assigned to the customer base acquired through the purchase of NMS and Chicago Resource, Inc., and goodwill, resulting from the purchase of Space Datagraphics Systems, Inc., in December 1994, are being amortized on a straight-line basis over ten years. RIGINC continuously evaluates and adjusts, if necessary, the net realizable value of these assets.

Income Taxes

RIGINC is a Subchapter S Corporation for federal income tax purposes under which income, losses, deductions and credits are allocated to and reported by the individual stockholders of the corporation. Accordingly, no provision for income tax has been recorded in the financial statements. Upon the effectiveness of the Registration Statement on Form S-1 (see note 10), RIGINC will become part of Realty Information Group, Inc., the successor, and will be taxed as a C-Corporation. Had the S-Corporation operated as a C-Corporation for the year ended December 31, 1995, 1996 and 1997 and the three months ended March 31, 1998, there would be no income taxes recorded as a result of the losses for the periods. NMS is a corporation which provides for income taxes under the provisions of Statement of Financial Accounting Standards No. 109. As of December 31, 1997, NMS had net loss carryforwards of approximately $522,000. A valuation allowance has been established against the related net deferred tax asset in its entirety.

Unit Based Compensation

In October 1995, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation" which is effective for the RIGLP's financial statements after 1995. SFAS No. 123 allows companies to account for stock-based compensation under the provisions of either SFAS No. 123 or Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees", with pro forma disclosure as if the measurement provision of SFAS No. 123 had been adopted. RIGINC applies these principles and accounts for RIGLP unit based compensation in accordance with the provisions of APB No. 25. As such, the adoption of SFAS No. 123 does not impact the financial position or results of operations of RIGINC.

Advertising Costs

Advertising costs are expensed as incurred. Such costs included in selling and marketing expense totaled approximately $125,698, $203,659, $397,966 and $53,908 for the years ended December 31, 1995, 1996, and 1997 and the three months ended March 31, 1998, respectively.

Concentration of Credit Risk

RIGINC performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral. RIGINC maintains reserves for credit losses, and such losses have been within management's expectations. The credit risk in accounts receivable is mitigated by the large and widespread customer base and lack of dependence on individual customers. The carrying amount of the accounts receivable approximates their net realizable value.

Earnings (loss) Per Share

In February 1997, the Financial Accounting Standards Board issued Statement No. 128, Earnings per Share. The effect of options, warrants or convertible securities are not included in the earnings per share calculation as they are anti-dilutive. All earnings per share amounts for all periods have been presented to conform to the Statement 128 requirements.

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Comprehensive Income", which is required to be adopted for the year ended December 31, 1998. SFAS 130 requires that an enterprise (a) classify items of other comprehensive income by their nature in the financial statements and (b) display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the Statements of Stockholders' Deficit. The implementation of SFAS 130, "Comprehensive Income", information on the financial statements is not expected to be material. For all periods presented, icluding the three months ended March 31, 1998, RIGINC had no items of Comprehensive Income and, accordingly, the Statement does not apply.

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related Information", which is required to be adopted for the year ended December 31, 1998. SFAS 131 changes the way public companies report segment information in annual financial statements and also requires those companies to report selected segment information in interim financial reports to stockholders. The disclosure for segment information on the financial statements is not expected to be material.

In October 1997, the AICPA issued SOP 97-2, Software Revenue Recognition, which changes the requirements for revenue recognition effective for transactions that the Company will enter into beginning January 1, 1998. The implementation of SOP 97-2 is not expected to have a material effect on the financial statements of RIGLP. As of January 1, 1998 the Company adopted AICPA SOP 97-2, Software Revenue Recognition, which was effective for transactions that RIGINC entered into in 1998. Prior years were not restated. The effect of adopting SOP 97-2 was not material in the financial statements of RIGINC. In March 1998, AcSEC issued SOP 98-4 which defers for one year the implementation of certain provisions of SOP 97-2. The issuance of SOP 98-4 had no effect on RIGINC.

3. ACQUISITIONS

On April 1, 1996, RIGLP expanded to the Chicago area by purchasing substantially all of the assets and liabilities of Chicago ReSource, Inc. ("CRI"), through the issuance of 114,640.55 partnership units valued at $1,200,000. On March 1, 1997 RIGLP expanded to the San Francisco area through a purchase of 99.3% of the outstanding shares of New Market Systems, Inc. ("NMS"), a California corporation, through the exchange of 14,710 partnership units valued at $206,000 and payment of $550,000 in cash. The accompanying statements of operations reflect the operating results of CRI and NMS since the effective date of the acquisition. Except for cash acquired, these transactions have been excluded from the statements of cash flows and have been accounted for using purchase accounting.

The pro forma unaudited results of operations for the years ended December 31, 1996 and 1997, assuming the purchase of CRI and NMS had been consummated as of January 1 of each year, respectively, are as follows:

5. LINE OF CREDIT

In October, 1997, RIGINC entered into a $1,000,000 line of credit agreement with Silicon Valley East (a Division of Silicon Valley Bank). The line bears interest at the bank's prime rate plus 2%, and has a one year term. Borrowings under the line are secured by the assets of RIGINC. RIGINC is in compliance at December 31, 1997, with the terms of the line of credit agreement which includes covenants requiring minimum cash, working capital and partners' capital amounts, and limits operating losses of RIGINC. At December 31, 1997, $1,000,000 of borrowings were outstanding under the line. Interest paid in 1997 totaled $17,760.

6. RELATED PARTY TRANSACTIONS

During 1997, RIGINC obtained a commitment from a shareholder for an additional $1,000,000 of subordinated, unsecured credit, bearing interest at a rate equal to that of the line of credit. In connection with the commitment, the individual has received warrants for the purchase of 15,000 shares of stock, exerciseable only in the event of an initial public offering or an equity funding in excess of $5.0 million ("a triggering event"). The warrants have a two year term beyond the triggering event and provide for the purchase of an equivalent number of shares at a price of 10% less than the price of the stock sold in an initial public offering or an equity funding in excess of $5.0 million. At December 31, 1997, $650,000 of borrowings were outstanding under the commitment and have been advanced to RIGINC. Interest paid in 1997 totaled $8,055.

Commencing in May 1995 RIGINC agreed to pay an investor $10,000 per month and the Chairman of RIGINC $6,667 per month for consulting services. During 1995, 1996 and 1997, RIGINC incurred fees of approximately $130,000, $200,000 and $200,000, respectively, related to such consulting services.

7. COMMITMENTS

RIGLP leases office space and equipment under operating lease agreements which expire at various dates through the year 2001. Lease agreements provide for various renewal terms and reimbursement of taxes, maintenance, insurance and other occupancy expenses applicable to the leased premises or property. In addition, RIGLP, as lessor, also subleases a portion of its office space to another tenant under a cancelable lease.

8. COMMON STOCK AND SALES OF PARTNERSHIP UNITS

In March 1996, the Company recorded a 40:1 stock split, and in January of 1997, a 1000:928 reverse stock split. All share amounts and transaction have been restated to reflect the stock splits as of January 1, 1995.

During 1995 RIGLP sold 327,780 limited partnership units to two investors for total net proceeds of approximately $3.3 million. The transaction granted the investors liquidation preferences of the investment plus a 6% per annum return in the event of a liquidation. In addition, beginning April 15, 1999 through April 15, 2001, the transaction allows the investors to liquidate their investments under a range of alternative strategies and exit transactions. The proceeds of the transaction were used to retire a related party note payable and to fund RIGLP's working capital needs.

On December 3, 1996, RIGLP completed a private placement (the "Private Placement") in which RIGLP raised approximately $5.0 million through the sale of 338,580.2 partnership units. The proceeds of the transaction were used to fund RIGLP's working capital needs and the NMS acquisitions.

In May 1997, RIGLP issued 21,428 partnership units valued at $300,000 to provide compensation to an officer, $150,000 of which had been accrued at December 31, 1996.

9. EMPLOYEE BENEFIT PLANS

Unit Option Plan

In March 1996 RIGLP adopted the 1996 Unit Option and Unit Purchase Plan (the "Plan"), under which 200,000 partnership units were reserved for issuance upon the exercise of options granted to officers, executive personnel, directors and key employees. Certain options previously granted were included in the Plan. The option plan is administered by the Board of Directors of RIGINC. Options are granted at prices which the Board of Directors of RIGINC believes approximate the fair market value of its limited partnership units. Individual grants become exercisable over a period of three years from the date of grant. The contractual term of the options range from three to ten years from the date of grant.

During 1996 RIGLP adopted the disclosure-only provisions of SFAS No. 123. Accordingly, no compensation cost has been recognized for the Plan. Had compensation expense related to the Plan been determined based on the fair value at the grant date for options granted in 1995, 1996 and 1997 consistent with the provisions of SFAS No. 123, RIGLP's pro forma net loss would have been $817,408, $2,690,009 and $3,337,420 as of December 31, 1995, 1996 and 1997, respectively. Such pro forma results are not representative of the effects on operations for future years.

The fair value of each option grant is estimated on the date of grant using the Minimum Value option-pricing model with the following weighted-average assumptions: dividend yield of 0%; risk-free interest rate of approximately 6.0%; and expected life of 3 years for 1995 grants and 4 years for 1996 and 1997 grants.

The following table summarizes information regarding unit options outstanding at December 31, 1997:

JAMISON RESEARCH, INC.
NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

Jamison Research, Inc. ("Jamison") was incorporated in the State of Georgia on January 19, 1984. Jamison develops and maintains a proprietary database of commercial real estate information in the Atlanta and Dallas metropolitan areas using proprietary software that permits access to its database. The database and software are distributed to its clients under monthly and annual license agreements. Jamison also provides various market specific reports using its database of information which are sold on an individual and subscription basis.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of the 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 at the date of the financial statements and the associated amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

Jamison recognizes revenue from the sale of licenses to the database on a straight line basis over the term of the license agreement which is typically one year or less. Revenue from market specific reports are recognized when delivered to the customer.

Cash and Cash Equivalents

Jamison's cash and cash equivalents include highly liquid investments purchased with an original maturity of less than three months.

Property and Equipment

Property and equipment, including leasehold improvements, are stated at cost and depreciated using the straight-line method over estimated useful lives of three to seven years. Leasehold improvements are amortized over the lesser of the related lease term or the useful life.

Capitalized Product Development Costs

Initial costs to develop and produce proprietary software and database products, including direct labor, contractors and applicable overhead are capitalized from the time technological feasibility is determined until product release. Prior to technological feasibility, such costs are classified as software development and expensed as incurred. Amortization of capitalized costs is based on the greater of the amount computed using (a) the ratio of current gross revenues to the sum of current and anticipated gross revenues, or (b) the straight-line method over the remaining estimated economic life of the product, typically five years, after product release.

Concentration of Credit Risk

Jamison performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral. Jamison maintains reserves for credit losses, and such losses have been within management's expectations. The credit risk in accounts receivable is mitigated by the large customer base and lack of dependence on individual customers. The carrying amount of the accounts receivable approximates their net realizable value.

NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

Income Taxes

Jamison provides for income taxes under the provisions of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes," which requires recognition of deferred tax assets and liabilities for expected future tax consequences of events that have been included in the financial statements or income tax returns. Under this method, deferred tax assets and liabilities are determined based upon the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Jamison recognizes revenue and expenses on a cash basis for tax purposes while using the accrual method for book purposes.

Earnings (loss) Per Share

In February 1997, the Financial Accounting Standards Board issued Statement No. 128, Earnings per Share. Jamison has no dilutive options, warrants or convertible securities. All earnings per share amounts for all periods have been presented to conform to the Statement 128 requirements.

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130 ("SFAS 130"), "Comprehensive Income", which is required to be adopted for the year ended December 31, 1998. SFAS 130 requires that an enterprise (a) classify items of other comprehensive income by their nature in the financial statements and (b) display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the Statements of Stockholders' Deficit. The implementation of SFAS 130, "Comprehensive Income", on the financial statements is not expected to be material. For all periods presented, including the three months ended March 31, 1998, RIGLP had no items of comprehensive income and, accordingly, the Statement does not apply.

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related Information", which is required to be adopted for the year ended December 31, 1998. SFAS 131 changes the way public companies report segment information in annual financial statements and also requires those companies to report selected segment information in interim financial reports to stockholders. The disclosure of segment information on the financial statements is not expected to be material.

In October 1997, the AICPA issued SOP 97-2, Software Revenue Recognition, which changes the requirements for revenue recognition effective for transactions that the Company will enter into beginning January 1, 1998. The implementation of SOP 97-2 is not expected to have a material effect on the financial statements of Jamison. As of January 1, 1998 the Company adopted AICPA SOP 97-2, Software Revenue Recognition, which was effective for transactions that Jamison entered into in 1998. Prior years were not restated. The effect of adopting SOP 97-2 was not material in the financial statements of Jamison. In March 1998 AcSEC issued SOP 98-4 which defers for one year the implementation of certain provisions of SOP 97-2. The issuance of SOP 98-4 had no effect on Jamison.

Operating Leases

Jamison leases office space in Atlanta and Dallas under non-cancelable operating lease agreements. The leases generally provide for renewal terms and Jamison is required to pay a portion of common area expenses including maintenance, real estate taxes and other expense. Rent expense for the years ended December 31, 1996 and 1997 was $108,114 and $128,529, respectively. As of December 31, 1997, payments due under non-cancelable operating leases are as follows:

1998 ........................  $ 170,200
1999 ........................    146,000

                               =========

Employment Agreements

During 1991 Jamison entered in an employment service termination agreement with a former employee of Jamison, whereby Jamison is required to pay the former employee up to $25,000 upon a change in ownership of Jamison. As of December 31, 1997, no amount has been recorded in the financial statements for this contingency.

In December 1997, Jamison entered into a one year employment agreement with an employee of Jamison. Pursuant to this agreement, upon the sale of a majority of Jamison's outstanding shares to a third party, Jamison is required to pay the employee 5.25 % of the amount of the sales price exceeding $7,500,000 less certain expenses. As of December 31, 1997, no amount has been recorded in the financial statements for this contingency.

4. RELATED PARTY TRANSACTIONS

During 1996 Jamison's two stockholders entered into a personal line of credit agreement with a bank. During 1996 and 1997 the stockholders used the proceeds from the line of credit agreement to advance Jamison cash to support operations and expansion. As of December 31, 1996 and 1997 outstanding advances due to the stockholders were approximately $180,000 and $111,000, respectively. Jamison repays principal and interest (approximately 8.25% annually), directly to the bank on behalf of the stockholders.

In December 1997, Jamison transferred title of two vehicles with a net book value of approximately $27,000 to the stockholders and recorded non-cash compensation.

Jamison paid interest of approximately $12,700 and $23,800 in 1996 and 1997, respectively.

5. INCOME TAXES

Jamison accounts for taxes under Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). Under SFAS 109, deferred tax liabilities and assets are determined based on the difference between financial statement and tax basis of assets and liabilities using enacted rates expected to be in effect during the year in which the differences reverse. Deferred taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes. These differences relate principally to reporting on the cash basis for tax purposes. Jamison paid no income taxes in 1996 or 1997 utilizing net operating losses in 1997.

Jamison's provision for income taxes resulted in effective tax rates that varied from the statutory federal income tax rate as follows:

6. NON CASH TRANSACTIONS

In 1996 and 1997 Jamison entered into arrangements with various vendors whereby such vendors provided various office equipment and office space in exchange for licenses to access Jamison's commercial real estate database. As a result of these transactions, Jamison recorded property and equipment of approximately $60,000 and $52,000, and expenses of approximately $42,000 and $53,000 in 1996 and 1997, with a corresponding credit to deferred revenue to be recognized in accordance with Jamison's revenue recognition policies. The value of the licenses has been determined to equal the fair value of the equipment received and office space used.

7. MANAGEMENT'S PLANS

Related to a filing of a Registration Statement on Form S-1 by Realty Information Group, Inc., Jamison and the stockholders of Jamison anticipate entering into an Agreement and Plan of Contribution ("Agreement") with Realty Information Group, Inc., OLD RIG, Inc., and Realty Information Group, L.P. to contribute all of Jamison's outstanding common stock to Realty Information Group, Inc. in exchange for common stock of Realty Information Group, Inc. Pursuant to the Agreement, the employment agreements (Note 3) will be paid by the current stockholders of Jamison prior to the completion of the transaction as described in the Agreement.

ITEM 13. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

Estimated expenses in connection with the issuance and distribution of the securities being registered, other than underwriting compensation, are as follows:

Securities and Exchange Commission registration fee ...............    $ 11,000
National Association of Securities Dealers, Inc. filing fee .......       4,000
Nasdaq National Market entry fee ..................................      50,000
Legal fees and expenses ...........................................     350,000
Accountants' fees and expenses ....................................     200,000
Printing and engraving expenses ...................................     150,000
Transfer Agent and Registrar fees and expenses ....................       2,500
Miscellaneous .....................................................     182,500
 Total ............................................................    $950,000
                                                                       ========

The Company will bear all of the foregoing fees and expenses.

The foregoing, except for the Securities and Exchange Commission registration fee, the National Association of Securities Dealers, Inc. filing fee and the Nasdaq National Market entry fee, are estimates.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

The Registrant's Certificate of Incorporation provides that the Registrant shall, subject to certain limitations, indemnify its directors and officers against expenses (including attorneys' fees, judgments, fines and certain settlements) actually and reasonably incurred by them in connection with any suit or proceeding to which they are a party so long as they acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to a criminal action or proceeding, so long as they had no reasonable cause to believe their conduct to have been unlawful.

Section 102 of the Delaware General Corporation Law permits a Delaware corporation to include in its certificate of incorporation a provision eliminating or limiting a director's liability to a corporation or its stockholders for monetary damages for breaches of fiduciary duty. The enabling statute provides, however, that liability for breaches of the duty of loyalty, acts or omissions not in good faith or involving intentional misconduct, or knowing violation of the law, and the unlawful purchase or redemption of stock or payment of unlawful dividends or the receipt of improper personal benefits cannot be eliminated or limited in this manner. The Registrant's Certificate of Incorporation includes a provision which eliminates, to the fullest extent permitted, director liability for monetary damages for breaches of fiduciary duty.

ITEM 17. UNDERTAKINGS

The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

EXHIBIT
EMPLOYMENT AGREEMENT

THIS AGREEMENT is executed as of the 24th day of April, 1998, and effective as of January 1, 1998 (the "Effective Date"), by and between OLD RIG, Inc. ("OLD RIG" and, prior to the Assignment (defined below), the "Company"), a Delaware corporation which is the general partner of Realty Information Group, L.P. ("RIGLP"), a Delaware pimited partnership, and ANDREW C. FLORANCE ("Executive").

WHEREAS, Executive has been heretofore employed as President and Chief Executive Officer of OLD RIG;

WHEREAS, OLD RIG desires to retain Executive in his capacity as President and Chief Executive Officer;

WHEREAS, Executive desires to remain President and Chief Executive Officer of OLD RIG upon the terms and conditions hereinafter set forth; and

WHEREAS, Executive and OLD RIG acknowledge that it is presently contemplated that, in connection with an initial public offering (the "Offering") of, or other significant transaction involving, the stock of Realty Information Group, Inc., a Delaware corporation ("RIG" and, after the Assignment (defined below), the "Company"), formerly known as Realty Information Group
(Delaware), Inc., (i) OLD RIG and RIGLP will be consolidated with RIG, and (ii)
this Employment Agreement will be automatically assigned to and assumed by RIG pursuant to Section 19 without further action by any party.

NOW, THEREFORE, the parties hereto, intending to be legally bound hereby, and in consideration of the mutual covenants herein contained, agree as follows:

1. Employment. As of the Effective Date, OLD RIG hereby continues the employment of Executive, and Executive hereby agrees to such continued employment, upon the terms and conditions set forth herein.

2. Duties. Executive shall be the President and Chief Executive Officer ("CEO") of the Company. Executive shall perform such executive duties as are consistent with the role of the President and CEO of the Company and the reasonable directions of the Board. Executive shall report to, and be subject to the authority of, the Board.

3. Extent of Services. Subject to this Section 3, Executive agrees to devote all his business time to the business of the Company. Executive shall not, without the prior written consent of the Company, during the term of his employment with the Company under this Agreement, be engaged in any other business activity whether or not such business activity is pursued for gain, profit, or other pecuniary advantage; but, subject to Section 8, this shall not be construed as preventing Executive from (i) investing his and his family's assets in such form or


manner as will not require the direct performance of services (except as a director, in the manner hereinafter permitted in clause (ii) below) by Executive in the operation of the affairs of the enterprises or companies in which said investments are made; (ii) acting as a director, trustee, or officer of, or participating as a member of a committee of, any firm or corporation other than the Company or an affiliate of the Company where such positions do not unreasonably interfere or conflict with the duties and responsibilities of Executive as the CEO of the Company; provided, however, that service in such capacity with each such entity has been approved by the Board; or (iii) acting as a director, trustee or officer of, or participating as a member of a committee of, any non-profit or community organization where such position does not unreasonably interfere or conflict with the duties and responsibilities of Executive as the CEO of the Company.

4. Compensation.

(a) The salary of Executive under this Agreement shall be at the rate of One Hundred Seventy-Five Thousand Dollars ($175,000) per year (the "Base Salary"). Base Salary shall be payable in biweekly or such other installments as shall be consistent with the Company's payroll procedures for its senior executives.

(b) The Company shall adopt as of January 1, 1998, and maintain for the benefit of Executive during the term of Executive's employment under this Agreement (and, where applicable, for such period thereafter as Executive is entitled to payments thereunder pursuant to this Agreement) a bonus program (the "Bonus Program"), which will provide Executive with an opportunity to receive an annual cash bonus of up to 100% of Base Salary based on the attainment of performance objectives set forth in Exhibit A. The annual bonus shall be paid within one hundred twenty calendar days of the end of the year for which it is earned. During the Term, the Bonus Program will be based on performance objectives established on a calendar year basis.

(c) RIG shall adopt as of the effectiveness of its initial public offering, and maintain for the benefit of Executive for as long as any options are outstanding, a Stock Option Plan (the "Stock Option Plan"). Under the Stock Option Plan, RIG will grant to Executive as of the effectiveness of the Offering an option to purchase 40,000 shares of RIG common stock with a strike price equal to the offering price of the stock in the Offering. Options granted to Executive under the Stock Option Plan may be non-qualified stock options or "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Such options shall have a life of not less than ten years and shall be exercisable in accordance with the terms of the Stock Option Plan, unless otherwise provided for in this Agreement. If Employee does not exercise an option on or prior to the date the option expires or is no longer exercisable, Employee shall be deemed to have made a "cashless exercise" and RIG shall pay to Employee within thirty days of the cashless exercise a cash payment equal to the total number of shares underlying the option or options multiplied by a number equal to the difference between the price of RIG's stock on the date of the cashless exercise and the exercise price of the option; provided, however, that the cashless exercise alternative shall not be available if Executive's employment has been terminated by RIG with cause (as defined in Section 7(b)) or by Executive without good reason (as defined in Section

- 2 -

7(c)). Such options shall vest: 25% upon the effectiveness of the Offering; 25% on December 31, 1998; 25% on December 31, 1999; and 25% on December 31, 2000.

(d) In addition to the options granted pursuant to Section
4(c), Executive shall be granted additional options under the Stock Option Plan to purchase 25,000 shares of RIG common stock with a strike price equal to the offering price of the stock in the Offering. Such options (the "Stub Period Bonus Options") shall be granted upon consummation of the Offering and shall be in lieu of Executive's right to receive from the Company a cash bonus for the period May 1, 1997 through December 31, 1997. The Stub Period Bonus Options shall be subject to the same vesting and exercise rules as the options granted to Executive under Section 4(c) of the Agreement.

(e) Nothing contained in this Section 4 shall prevent the Board from adopting additional compensation arrangements for Executive or providing additional benefits under any of the existing compensation arrangements.

5. Fringe Benefits. During the term of Executive's employment under this Agreement, the Company shall provide to Executive term life insurance coverage not to exceed a total of One Million Dollars ($1,000,000) (provided that Executive shall be insurable at a cost not exceeding $2,000 per year), which such benefits will be payable as designated by Executive, six weeks of paid vacation per year earned ratably over the year (provided, however, that Executive shall not accrue more than six weeks of paid vacation), and the same health insurance, accident and disability insurance, life insurance, and such other fringe benefits, as are provided to the most senior executives of the Company.

6. Term. The term of Executive's employment under this Agreement shall commence on the Effective Date and shall continue for an initial term (the "Initial Term") extending through December 31, 2000, and for automatic and successive renewal terms of one (1) year each (each, a "Renewal Term" and collectively, the "Renewal Terms"), unless either the Company or Executive elects not to extend the term beyond the Initial Term or any Renewal Term (herein, the Initial Term or a Renewal Term is sometimes referred to as the "Current Term") and gives to the other party hereto written notice of termination at least six (6) months prior to the end of the Initial Term, or three (3) months prior to the end of the Renewal Term, as applicable.

7. Termination.

(a) By the Company Without Cause. The Company may terminate Executive's employment at any time, without Cause (as defined herein), upon sixty (60) days written notice to Executive. If the Company terminates Executive's employment without Cause, Executive: (x) shall receive through the later of (i) the expiration of the Current Term or (ii) one year from the date of termination, the compensation provided for under paragraph 4(a) of this Agreement; (y) shall be entitled to receive the bonus he would have received under the Bonus Program (as in effect on the date of termination) as if he continued in the position he held immediately prior to termination for the balance of the calendar year in which such termination occurs; and (z) shall be, if not

- 3 -

otherwise, fully vested in all stock options granted to Executive under the Stock Option Plan (as in effect on the date of termination) and any predecessor stock option plan or program. Upon termination of Executive's employment without Cause, the exercise period for all vested options shall be one-hundred eighty
(180) days after cessation of employment.

(b) By the Company For Cause. Notwithstanding anything herein to the contrary, the Company shall have the right to terminate Executive's employment under this Agreement for "Cause." For the purposes of this Agreement, the term "Cause" shall mean (i) a material failure by Executive to perform his duties hereunder which shall persist uncured by Executive for a sixty (60) day period after written notice is given to Executive which details the duties which the Company alleges Executive has failed to perform; (ii) Executive being convicted of a felony or Executive pleading nolo contendere to a felony; or (iii) any other willful act or omission by Executive, which is materially injurious to the financial condition or business reputation of the Company or its affiliates, including without limitation any violation during the term of Executive's employment of Executive's obligations under Section 8 hereof. Executive will not receive Base Salary or Fringe Benefits with respect to any period after his termination for Cause. Upon termination of Executive's employment with Cause, (A) Executive shall forfeit (x) all right to participate in the Bonus Program and (y) all unvested stock options, and (B) the exercise period for all vested options shall be sixty (60) days after cessation of employment.

(c) By Executive For Good Reason. Executive shall have the right to voluntarily terminate his employment for Good Reason upon at least sixty (60) days prior written notice to the Company. For purposes of this Agreement, Good Reason shall mean (i) Executive is required to relocate his principal office more than forty-five (45) miles from its current location in Bethesda, Maryland; (ii) Executive ceases involuntarily to be CEO of the Company (or any successor) or is required to perform duties materially inconsistent with the duties normally performed by a chief executive officer; (iii) the Company (or any successor) takes actions which constitute a material diminution of Executive's position or title with the Company or in the nature of Executive's authority, duties or responsibilities; (iv) Executive is required to report to an individual or entity other than the Board; or (v) a material breach by the Company of its obligations hereunder which shall persist uncured by the Company for a ninety (90) day period after written notice is given to the Company which details the obligations which Executive alleges the Company has breached; (vi) there is a Material Change (as defined herein) with respect to the Company and Executive terminates his employment within one year after the Material Change. For purposes of this Agreement, a Material Change is defined as the occurrence of any of the following events:

(1) The acquisition (in one or more transactions) of beneficial ownership of more than 50% of the outstanding shares of common stock of the Company by any person or entity or by any group of persons or entities acting in concert for the purpose of acquiring, voting, holding or disposing of shares of the Company's common stock (other than as a result of (x) the consolidations of OLD RIG, RIGLP and Jamison Research, Inc. described in the recitals, (y) the completion of an initial public offering or (z) the acquisition of stock by any person who is a stockholder of OLD RIG or a partner of RIGLP as of the Effective Date);

- 4 -

(2) The election or appointment (in one or more elections or as a result of one or more appointments to fill vacancies) as directors comprising one-half (1/2) or more of the Board of persons who were not nominated, recommended or appointed by the Company's incumbent Board (including as incumbent directors all directors who were nominated, recommended or approved by a majority of the Board composed of persons who were incumbent directors);

(3) The Company's merging with any other entity in a transaction in which the Company is not the surviving entity;

(4) The sale by the Company (in one or more transactions) of all or substantially all of its assets. If Executive terminates his employment for Good Reason, Executive: (x) shall receive through the later of (i) the expiration of the Current Term or (ii) one year from the date of termination, the compensation provided for under paragraph 4(a) of this Agreement; (y) shall be entitled to receive the bonus he would have received under the Bonus Program (as in effect on the date of termination) as if he continued in the position he held immediately prior to termination for the balance of the calendar year in which such termination occurs; and (z) shall be, if not otherwise, fully vested in all outstanding Stock Options granted to Executive under the Stock Option Plan (as in effect on the date of termination) and any predecessor stock option plan or program. Upon termination of Executive's employment with Good Reason, the exercise period for all vested options shall be one-hundred eighty (180) days after cessation of employment.

(d) By Executive Without Good Reason. Executive shall have the right to voluntarily terminate, for any reason other than Good Reason, his employment with the Company upon one-hundred eighty (180) days written notice to the Company. Executive will not receive Base Salary or Fringe Benefits with respect to any period after his termination without Good Reason. Upon termination of Executive's employment without good reason, (i) Executive shall forfeit (x) all right to participate in the Bonus Program and (y) all unvested stock options, and (ii) the exercise period for all vested options shall be sixty (60) days after cessation of employment.

8. Confidentiality, Invention and Non-Compete Agreement.

(a) During the term of this Agreement, and thereafter for the duration of the period, if any, that Executive continues to be employed by the Company and/or any other entity owned by or affiliated with the Company or on an "at will" basis, and thereafter for the Non- Competition Period (defined below), Executive shall not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, company, partnership, corporation, business, group, or other entity (each, a "Person"):

(i) engage, as an officer, director, shareholder, owner, partner, member, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant, advisor, or sales representative, in any group or division of a business selling any

- 5 -

products or services in direct competition with the Company in the United States, Canada, the United Kingdom or other nations in which the Company is conducting or in which he was aware the Company had plans to conduct business within the twelve months following his termination (the "Territory"); provided, however, that the foregoing covenant shall not be deemed to prohibit Executive from acquiring as an investment not more than one percent (1%) of the capital stock of a competing business whose stock is traded on a national securities exchange or over-the-counter;

(ii) call upon any Person who is, at that time, within the Territory, an employee of the Company for the purpose or with the intent of enticing such employee out of the employ of the Company;

(iii) call upon any Person who or that is, at the time of termination, or has been, within one year prior to that time, a customer of the Company within the Territory for the purpose of soliciting or selling products or services in direct competition with the Company within the Territory; or

(iv) on Executive's own behalf or on behalf of any competitor, call upon any Person as a prospective acquisition candidate for an entity other than the Company or its affiliates who or that, during Executive's employment by the Company was, to Executive's knowledge, either called upon by the Company as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by the Company. Executive, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that the Company had called upon such candidate or made an acquisition analysis thereof.

(b) Executive acknowledges that during the course of his employment, he may develop and obtain access to trade secrets, proprietary software and other "confidential business information" of the Company, such as its software systems, sources of data, databases and other competitively sensitive information kept in confidence by the Company such as selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, and internal financial statements. Executive agrees to not use or disclose any trade secrets, proprietary software or confidential business information to which he is exposed or has access in the course of his employment with the Company, even if elements of any of them may belong to third parties, during his employment and for so long afterwards as the Company seeks to maintain as confidential the proprietary software, trade secrets or confidential business information, whether or not the software, trade secrets and confidential business information are in written or tangible form, except as required and authorized during the performance of Executive's duties for and with the Company. Executive agrees that, given the nature of the Company's business and business plans there will never come a time when disclosure of the Company's proprietary software, trade secrets or confidential information would not be seriously injurious to the Company.

(c) Executive acknowledges that he has been employed by the Company during its critical developmental and roll-out stages and that leaving the employ of the Company to

- 6 -

join any business competitor would seriously hamper the business of the Company. Accordingly, Executive agrees that the Company shall be entitled to injunctive relief to prevent him from violating this Section 8, in addition to all remedies permitted by law, to enforce the provisions of this Agreement. Executive further acknowledges that his training, experience and technical skills are of such breadth that they can be employed to Executive's advantage in other areas which are not in direct competition with the business of the Company on the date of termination of Executive's employment and consequently the foregoing obligations will not unreasonably impair Executive's ability to engage in business activity after the termination of Executive's employment.

(d) For purposes of this Section 8, the term "Company" shall mean the Company and each of its subsidiaries and predecessors in interest; the term "Non-Competition Period" shall mean the period commencing on the date hereof to and including the second anniversary of the date on which Executive ceases to be employed by the Company (provided, however, that the Non-Competition Period, during which the agreements and covenants of Executive made in this Section 8 shall be effective, shall be computed by excluding from such computation any time during which Executive is in violation of any provision of this Section 8).

(e) The covenants in this Section 8 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. If any provision of this Section 8 relating to the time period or geographic area of the restrictive covenants shall be declared by a court of competent jurisdiction to exceed the maximum time period or geographic area, as applicable, that such court deems reasonable and enforceable, said time period or geographic area shall be deemed to be, and thereafter shall become, the maximum time period or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination. Upon termination of this Agreement for any reason, the covenants specified in this Section 8 shall survive for the term specified herein.

(f) All of the covenants in this Section 8 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of such covenants.

9. Disability. In the event Executive shall become disabled so that he is unable to perform the essential duties of his position with reasonable accommodation ("Disability" or "Disabled") for more than six (6) consecutive months or should the Disability exist for more than nine (9) months in any twelve (12) month period, the Company shall have the right to terminate Executive's employment and, upon such termination of employment, the Company shall thereafter have no obligation to provide Executive compensation or Executive benefits of any kind; provided, however, that (i) a pro rata portion of Executive's unvested stock options that would have otherwise vested during the calendar year of his termination shall vest immediately, and (ii) Executive shall receive a pro rata bonus under the Bonus Program based on the bonus Executive would have received for the calendar year of termination if he remained employed by the Company through the

- 7 -

end of the Calendar Year. Such pro rata benefits shall be determined by multiplying the number of unvested options that would have vested in the calendar year of termination, or the amount of bonus, as the case may be, by a fraction, the numerator of which is the number of complete weeks Executive was employed during the year of termination and the denominator of which is fifty-two. Upon termination of Executive's employment for Disability, the exercise period for all vested options shall be one year after cessation of employment.

10. Death. In the event of Executive's death, Executive's estate shall become entitled to any earned but unpaid compensation owed to Executive pursuant to paragraph 4(a) of this Agreement. Neither Executive's estate nor any of Executive's beneficiaries shall be entitled to any additional amounts of earned but unpaid compensation following Executive's death; provided, however, that (i) a pro rata portion of Executive's unvested stock options that would have vested in the year of his termination shall vest immediately, and
(ii) Executive shall receive a pro rata bonus under the Bonus Program based on the bonus Executive would have received for the calendar year of termination if he remained employed by the Company through the end of the calendar year. Such pro rata benefits shall be determined by multiplying the number of unvested options that would have vested in the calendar year of termination, or the amount of bonus, as the case may be, by a fraction, the numerator of which is the number of complete weeks Executive was employed during the year of termination and the denomination of which is fifty-two. In the event of Executive's death, the exercise period for all vested options shall be one year after Executive's death.

11. Insurance. Employer shall have the right to purchase such policies of insurance on the life of Executive as may be determined by Employer in its sole discretion, and as may be available, at the sole cost and expense of Employer, and naming Employer as owner and beneficiary, and Executive shall cooperate in the placement thereof.

12. Reimbursement of Expenses. The Company shall reimburse Executive for all reasonable expenses incurred in carrying out his duties under this Agreement, including reasonable attorneys' fees incurred by Executive in negotiating this Agreement. Executive shall present to the Company from him an itemized account of such expenses in a form required by the Company.

13. Arbitration. The parties agree that any dispute between the parties relating to this Agreement shall not be resolved in litigation, but instead shall be resolved in final, binding arbitration by a single arbitrator under the auspices of the American Arbitration Association ("AAA") in Washington, D.C. Any such arbitration shall be conducted in accordance to the AAA's Employment Dispute Resolution Procedures. The arbitrator shall require the losing party to pay the prevailing party's reasonable attorney's fees and costs of arbitration.

14. Notice. All notices which are or may be required to be given by either party to the other in connection with this Agreement and the transactions contemplated thereby shall be in writing, and shall be deemed to have been properly given if and when delivered personally or sent by certified mail, return receipt requested; addressed, if to the Company, to:

- 8 -

Michael R. Klein Chairman, Realty Information Group, Inc. 2425 Wyoming Street, N.W.

Washington, D.C. 20008

and if to Executive, to:

Andrew C. Florance
4948 Western Avenue
Bethesda, Maryland 20816

15. Waiver of Breach. The waiver by either party of a breach of any provisions of this Agreement by the other shall not operate or be construed as a waiver of any subsequent breach.

16. Due Authorization. OLD RIG represents and warrants to Executive that the execution, delivery and performance of this Agreement has been duly authorized on behalf of the OLD RIG and that this Agreement is valid and binding on OLD RIG and enforceable in accordance with its terms against OLD RIG.

17. Indemnification. Executive shall be indemnified for his actions as an officer and director of the Company in accordance with the by-laws of the Company.

18. Governing Law. The Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware.

19. Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the Company and its respective successors and assigns but the rights and obligations of Executive are personal and may not be assigned or delegated without the Company's prior written consent. Notwithstanding the preceding sentence, OLD RIG shall be permitted to assign all of its obligations hereunder to RIG and such assignment shall be deemed to have occurred upon the effectiveness of the consolidation of OLD RIG and RIGLP with RIG (the "Assignment").

20. Counterparts. This Agreement, for the convenience of the parties, may be executed in any number of counterparts, all of which when taken together shall constitute one and the same Agreement.

21. Entire Agreement concerning Employment; Supremacy of Employment Agreement. This Agreement constitutes the entire Agreement between the parties as to Executive's employment and compensation therefor and supersedes and replaces any and all agreements, written or oral, as to such matters. This Agreement may not be modified or amended orally, but only by an agreement in writing, signed by the party against whom enforcement of any waiver, change, modification, extension or discharge is sought. If there is any conflict with respect to Executive

- 9 -

between the provisions of this Agreement and the provisions of either the Bonus Program or the Stock Option Plan, as applicable, the provisions of this Agreement shall govern. If there is no such conflict, the provisions of the Bonus Plan or the Stock Option Plan, as applicable, shall govern.

22. Special Reimbursement. In the event that Executive's employment is terminated pursuant to clause (a) or (c) of Section 7 and he is assessed a tax pursuant to Section 4999 of the Code (the "Parachute Tax"), the Company shall immediately pay Executive that additional amount of money (the "Gross-Up Payment") which will put Executive in the same net after tax position had no Parachute Tax been incurred. The Gross-Up Payment shall be sufficient in amount to cover any income or excise tax on the Gross-Up Payment itself (and any interest or penalty imposed with respect to an excess parachute payment). In the event that the Parachute Tax is ultimately determined to exceed the amount taken into account in computing the Gross-Up Payment at the time of the termination of Executive's employment (including by reason of any payment the existence or amount of which could not be determined at the time of the Gross-Up Payment), the Company shall make an additional Gross-Up Payment in respect of such excess (and any interest, penalties or additions payable by Executive with respect to such excess) at the time that the amount of such excess is finally determined. Executive and the Company shall each reasonably cooperate with the other in connection with any administrative or judicial proceedings concerning the existence or amount of any such subsequent liability for the Parachute Tax. Notwithstanding the foregoing, the Company shall not have an obligation to include within the Gross-Up Payment any interest or penalty with respect to the Parachute Tax to the extent that (i) at least thirty (30) days prior to the date such Parachute Tax payment is due the Company provides Executive with its calculation of the Parachute Tax due and (ii) Executive could have avoided such interest or penalty by paying the amount due calculated by the Company pursuant to clause (i).

EMPLOYMENT AGREEMENT is executed this 24 day of April, 1998, and effective as of January 1, 1998 (the "Effective Date"), by and between OLD RIG, Inc. ("OLD RIG" and, prior to the Assignment (defined below), the "Company"), a Delaware corporation which is the general partner of Realty Information Group, L.P. ("RIGLP"), a Delaware limited partnership, and Frank A. Carchedi ("Executive").

WHEREAS, Executive has been heretofore employed by OLD RIG in the capacity of Chief Financial Officer;

WHEREAS, OLD RIG desires to retain Executive in such capacity;

WHEREAS, Executive desires to remain employed in such capacity by OLD RIG upon the terms and conditions hereinafter set forth; and

WHEREAS, Executive and OLD RIG acknowledge that it is presently contem plated that, in connection with an initial public offering (the "Offering") of, or other significant transaction involving, the stock of Realty Information Group, Inc., a Delaware corporation ("RIG" and, after the Assignment (defined below), the "Company"), formerly known as Realty Information Group
(Delaware), Inc., (i) OLD RIG and RIGLP will be consolidated with RIG, and (ii)
this Employment Agreement will be automatically assigned to and assumed by RIG pursuant to Section 15 without further action by any party.

NOW, THEREFORE, the parties hereto, intending to be legally bound hereby, and in consideration of the mutual covenants herein contained, agree as follows:

1. Employment. The Company agrees to employ Executive at the Company's offices in the greater Washington metropolitan area, and Executive agrees to be so employed, in the capacity of Chief Finanical Officer. Executive shall perform such functions and undertake such responsibilities as are assigned from time to time by the President of the Company or the Board of Directors. The Company and Executive agree that this agreement terminates and replaces any previous employment agreements between Executive and the Company.

2. Term. The term of Executive's employment under this Agreement shall commence on the Effective Date and shall continue for the initial term set forth of two (2) years (the "Initial Term"), and for automatic and successive renewal terms of one (1) year each (each, a "Renewal Term" and collectively, the "Renewal Terms"), unless either the Company or Executive elects not to extend the term beyond the Initial Term or any Renewal Term (herein, the Initial Term or a Renewal Term is sometimes referred to as the "Current Term") and gives to the other party hereto written notice of termination at least six (6) months prior to the end of the Initial Term or at least three (3) months prior to the end of the Renewal Term.


3. Full time and efforts. Executive shall diligently and conscientiously de vote his full time, exclusive attention and best efforts to his duties under this contract.

4. Compensation.

(a) Commencing as of the Effective Date of this Agreement and until the Offering, the Company shall pay Executive base compensation for his services at the annual rate then in effect under Executive's existing arrangements with the Company (the "Base Compensation"). Commencing as of the effective date of the Offering, Executive's Base Compensation shall be $125,000 per year. The President of the Company in consultation with the Compensation Committee of the Board of the Company will review Executive's performance and determine any appropriate increases annually thereafter. Base Compensation shall be pay able in biweekly or such other installments as shall be consistent with the Company's payroll procedures for its senior executives.

(b) In addition, Executive shall be eligible to earn an annual performance bonus (the "Annual Bonus") pursuant to criteria negotiated with the President and approved by the Compensation Committee of the Board of Directors of the Company. The Annual Bonus, if any, shall be paid within one-hundred twenty (120) days of the end of the relevant measuring period. It is expected that the Annual Bonus will be at a target level of not less than 25% nor more than 75% of the Base Compensation paid during such calendar year.

(c) RIG shall adopt as of the effectiveness of its Offering, and maintain for the benefit of Executive for as long as any options are outstanding, a Stock Option Plan (the "Stock Option Plan"). Under the Stock Option Plan, RIG will grant to Executive as of the effectiveness of the Offering an option to purchase such number of shares of RIG common stock as 12,849 units of RIGLP would be converted in the Offering. The exercise price of the options shall be the fair market value of such stock on the grant date (measured by the price of such stock determined at the pricing meeting of underwriters in connection with the Offering). Options granted to Executive under the Stock Option Plan may be non-qualified stock options or "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Such options shall vest: 25% upon the effectiveness of the Offering; 25% on December 31, 1998; 25% on December 31, 1999; and 25% on December 31, 2000.

(d) In full satisfaction of Executive's right to receive from the Company a cash bonus for the period through December 31, 1997, Executive shall receive $25,000 in cash, paid over two months.

(e) In the event that no Offering shall occur but the Company, OLD RIG or RIGLP shall consummate a Significant Equity Transaction during the term of this Agree ment, then immediately prior to the consummation of such transaction the Company, OLD RIG or RIGLP, as the case may be, shall grant to Executive options to purchase 40,000 shares of

- 2 -

common stock of the Company, 12,849 shares of OLD RIG or 12,849 units of RIGLP, as the case may be, at a price per share or unit equivalent to the price being paid by the purchaser in such Significant Equity Transaction. Such options will vest as provided in Section 4(c). For purposes of this clause (e), "Significant Equity Transaction" shall mean any equity funding of the Company, OLD RIG or RIGLP, as the case may be, in which the purchaser invests at least $15 million in such entity or entities.

5. Benefits. Executive shall be entitled to participate in, and receive benefits from any insurance, medical, disability, vacation or pension plan of the Company for which Executive satisfies the generally applicable criteria for eligibility, and to other perquisites which may be in effect at any time during the term hereof that are generally available to senior executive officers of the Company.

6. Expense reimbursement. The Company shall reimburse Executive for all categories of expenses incurred in carrying out his duties under this Agreement that the Company's policies regard as reasonable and necessary. Executive shall present to the Company from time to time an itemized account of such expenses in any form required by the Company.

7. Termination without cause.

(a) By the Company. The Company may terminate this Agreement without cause upon sixty (60) days' written notice. In such an event
(i) all of Executive's unvested options due to vest within the next twelve (12) months will vest and (ii) Executive will, as severance and liquidated damages and in consideration of his execution of a complete and absolute release of the Company and its officers from any and all further claims, receive (A) on a monthly basis, as if he had not been terminated, all payments (other than bonus) he would have received for the greater of (x) the term remaining under the Agreement had he not been terminated or (y) six months, and (B) a pro rata share of any bonus based upon that portion of such calendar year during which Executive was employed.

(b) By Executive. Executive may without cause terminate this Agreement, by giving one hundred eighty (180) days' written notice during the Initial Term, or ninety (90) days' written notice during any Renewal Term, to the Company. In such event, at the sole discretion of the Company, Executive shall continue to render all services. Executive shall be paid the base compensation, accrue bonus and vest options as provided by Section 4 up to the date of termination, but shall not receive any salary or bonus payment thereafter nor shall any stock option that is not otherwise vested or nonforfeitable on the date of termination become vested or nonforfeitable on such date.

8. Termination after merger or acquisition. In the event of the merger of the Company or the acquisition, directly or indirectly, of all or substantially all of the Company's assets or a controlling interest in the voting shares of the Company by an unaffiliated party (a "Change of Control"), Executive may elect to treat that event as a termination without cause

- 3 -

unless the new party: (a) extends to him a reasonable offer to (i) be retained by the Company in an executive position of responsibility, authority and compensation comparable in material respects (including location) to the position of Executive immediately prior to the Change of Control, (ii) retain all rights accorded under this Agreement and (iii) be afforded all privileges accorded to other executives of the Company; and (b) in fact retains Executive in such capacity for at least twelve (12) months after the Change of Control. Executive acknowledges and agrees that the transactions described in the fourth recital shall not constitute a "Change of Control."

9. Termination for cause. The Company may terminate this Agreement (a) for cause at any time by notifying Executive in writing of such termination and the cause thereof or (b) in the event of Executive's death or prolonged disability; provided, however, that the only grounds constituting cause shall be: (i) Executive's gross negligence in the performance of his duties hereunder, intentional nonperformance or mis-performance of such duties, or refusal to abide by or comply with the reasonable, material and documented directives of the Board, his superior officers, or the Company's material policies and procedures (including without limitation the provisions of Section 10 hereof), which actions continue uncured for a period of at least thirty (30) days after receipt by Executive of written notice of the need to cure or cease;
(ii) Executive's willful dishonesty, fraud, or misconduct with respect to the business or affairs of the Company; (iii) Executive's indictment for, conviction of, or guilty or nolo contendere plea to, a felony; and (iv) Executive's abuse of alcohol or drugs (legal or illegal), other than legal drugs taken under the direction of a physician, that, in the Company's reasonable judgment, materially impairs Executive's ability to perform his duties hereunder. In any such event, Executive will forfeit all unvested options and all claims to bonuses not yet awarded, and will be paid through the date of the termination; provided, however, that in the event of termination for death or prolonged disability, all unvested options shall immediately vest.

10. Confidentiality, Invention and Non-Compete Agreement.

(a) During the term of this Agreement, and thereafter for the duration of the period, if any, that Executive continues to be employed by the Company and/or any other entity owned by or affiliated with the Company or on an "at will" basis, and thereafter for the Non-Competition Period (defined below), Executive shall not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, company, partnership, corporation, business, group, or other entity (each, a "Person"):

(i) engage, as an officer, director, shareholder, owner, partner, member, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant, advisor, or sales representative, in any business selling any products or services in direct competition with the Company in the United States, Canada, the United Kingdom, or other nations in which the Company is conducting or in which he was aware the Company had plans to conduct business within the eighteen (18) months following his termina tion (the "Territory"); provided, however, that the foregoing covenant shall not be deemed to prohibit Executive from acquiring as an investment not more than one percent (1%) of the capital

- 4 -

stock of a competing business whose stock is traded on a national securities exchange or over- the-counter;

(ii) call upon any Person who is, at that time, within the Territory, an employee of the Company for the purpose or with the intent of enticing such employee away from or out of the employ of the Company;

(iii) call upon any Person who or that is, at that time, or has been, within one year prior to that time, a customer of the Company within the Territory for the purpose of soliciting or selling products or services in direct competition with the Company within the Territory; or

(iv) on Executive's own behalf or on behalf of any competitor, call upon any Person as a prospective acquisition candidate for an entity other than the Company or its affiliates who or that, during Executive's employment by the Company was, to Executive's knowledge, either called upon by the Company as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by the Company. Executive, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that the Company had called upon such candidate or made an acquisition analysis thereof.

(b) Executive acknowledges that during the course of his employment, he may develop and obtain access to trade secrets, proprietary software and other "confidential business information" of the Company, such as its software systems, sources of data, databases and other competitively sensitive information kept in confidence by the Company such as selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, and internal financial statements. Executive agrees to not use or disclose any trade secrets, proprietary software or confidential business information to which he is exposed or has access in the course of his employment with the Company, even if elements of any of them may belong to third parties, during his employment and for so long afterwards as the Company seeks to maintain as confidential the proprietary software, trade secrets or confidential business information, whether or not the software, trade secrets and confidential business information are in written or tangible form, except as required and authorized during the performance of Executive's duties for and with the Company. Executive agrees that, given the nature of the Company's business and business plans there will never come a time when disclosure of the Company's proprietary software, trade secrets or confidential information would not be seriously injurious to the Company.

(c) Executive acknowledges that he has been employed by the Company during its critical developmental and roll-out stages and that leaving the employ of the Company to join any business competitor would seriously hamper the business of the Company. Accordingly, Executive agrees that the Company shall be entitled to injunctive relief to prevent him from violating this Section 10, in addition to all remedies permitted by law, to enforce the

- 5 -

provisions of this Agreement. Executive further acknowledges that his training, experience and technical skills are of such breadth that they can be employed to Executive's advantage in other areas which are not in direct competition with the business of the Company on the date of termination of Executive's employment and consequently the foregoing obligations will not unreasonably impair Executive's ability to engage in business activity after the termination of Executive's employment.

(d) For purposes of this Section 10, the term "Company" shall mean the Company and each of its subsidiaries, predecessors in interest and successors; and the term "Non-Competition Period" shall mean the period commencing on the date hereof to and including the second anniversary of the date on which Executive ceases to be employed by the Company (provided, however, that the Non-Competition Period, during which the agreements and covenants of Executive made in this Section 10 shall be effective, shall be computed by excluding from such computation any time during which Executive is in violation of any provision of this Section 10).

(e) The covenants in this Section 10 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. If any provision of this Section 10 relating to the time period or geographic area of the restrictive covenants shall be declared by a court of competent jurisdiction to exceed the maximum time period or geographic area, as applicable, that such court deems reasonable and enforceable, said time period or geographic area shall be deemed to be, and thereafter shall become, the maximum time period or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination. Upon termination of this Agreement for any reason, the covenants specified in this Section 10 shall survive for the term specified herein.

(f) All of the covenants in this Section 10 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of such covenants.

11. Notices. All notices required or permitted to be given under this Agreement shall be given by certified mail, return receipt requested, to the parties at the following addresses or to such other addresses as either may designate in writing to the other party.

- 6 -

(a) If to the Company:

Andrew C. Florance Chief Executive Officer Realty Information Group 7475 Wisconsin Avenue Sixth Floor
Bethesda, Maryland 20814 Telefax: 301-718-2444

(b) If to Executive, to the address indicated below Executive's name on the signature page.

12. Arbitration. The parties agree that any dispute between the parties relating to this Agreement shall not be resolved in litigation, but instead shall be resolved in final, binding arbitration by a single arbitrator under the auspices of the American Arbitration Association ("AAA") in Washington, D.C. Any such arbitration shall be conducted in accordance to the AAA's Employment Dispute Resolution Procedures.

13. Waiver of Breach. The waiver by either party of a breach of any provisions of this Agreement by the other shall not operate or be construed as a waiver of any subsequent breach. A delay or failure by either party to exercise a right under this Agreement, or a partial or single exercise of that right, shall not constitute a waiver of that or any other right.

14. Governing Law. The Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware.

15. Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the Company and its respective successors and assigns but the rights and obligations of Executive are personal and may not be assigned or delegated without the Company's prior written consent. Notwithstanding the preceding sentence, OLD RIG shall be permitted to assign all of its obligations hereunder to RIG and such assignment shall be deemed to have occurred upon the effectiveness of the consolidation of OLD RIG and RIGLP with RIG (the "Assignment").

16. Counterparts. This Agreement, for the convenience of the parties, may be executed in any number of counterparts, all of which when taken together shall constitute one and the same Agreement.

17. Entire Agreement concerning Employment; Supremacy of Employment Agreement. This Agreement constitutes the entire Agreement between the parties as to Executive's employment and compensation therefor and supersedes and replaces any and all

- 7 -

agreements, written or oral, as to such matters. This Agreement may not be modified or amended orally, but only by an agreement in writing, signed by the party against whom enforcement of any waiver, change, modification, extension or discharge is sought. If there is any conflict with respect to Executive between the provisions of this Agreement and the provisions of either the bonus plan or the Stock Option Plan, as applicable, the provisions of this Agreement shall govern.

18. Amendments. This Agreement may be amended only in writing, signed by both parties.

In witness whereof, Company has by its appropriate officers, signed and affixed its seal and Executive has signed and sealed this Agreement, to be effective as of the last date noted below.

EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT is executed this 24 day of April, 1998,
and effective as of January 1, 1998 (the "Effective Date"), by and between OLD RIG, Inc. ("OLD RIG" and, prior to the Assignment (defined below), the "Company"), a Delaware corporation which is the general partner of Realty Information Group, L.P. ("RIGLP"), a Delaware limited partnership, and David M. Schaffel ("Executive").

WHEREAS, Executive has been heretofore employed by OLD RIG in the capacity of Vice President of Product Development;

WHEREAS, OLD RIG desires to retain Executive in such capacity;

WHEREAS, Executive desires to remain employed in such capacity by OLD RIG upon the terms and conditions hereinafter set forth; and

WHEREAS, Executive and OLD RIG acknowledge that it is presently contemplated that, in connection with an initial public offering (the "Offering") of, or other significant transaction involving, the stock of Realty Information Group, Inc., a Delaware corporation ("RIG" and, after the Assignment (defined below), the "Company"), formerly known as Realty Information Group
(Delaware), Inc., (i) OLD RIG and RIGLP will be consolidated with RIG, and (ii)
this Employment Agreement will be automatically assigned to and assumed by RIG pursuant to Section 15 without further action by any party.

NOW, THEREFORE, the parties hereto, intending to be legally bound hereby, and in consideration of the mutual covenants herein contained, agree as follows:

1. Employment. The Company agrees to employ Executive at the Company's offices in the greater Washington metropolitan area, and Executive agrees to be so employed, in the capacity of Vice President of Product Development. Executive shall perform such functions and undertake such responsibilities as are assigned from time to time by the President of the Company or the Board of Directors. The Company and Executive agree that this agreement terminates and replaces any previous employment agreements between Executive and the Company.

2. Term. The term of Executive's employment under this Agreement shall commence on the Effective Date and shall continue for the initial term set forth of two (2) years (the "Initial Term"), and for automatic and successive renewal terms of one (1) year each (each, a "Renewal Term" and collectively, the "Renewal Terms"), unless either the Company or Executive elects not to extend the term beyond the Initial Term or any Renewal Term (herein, the Initial Term or a Renewal Term is sometimes referred to as the "Current Term") and gives to the other party hereto written notice of termination at least six (6) months prior to the end of the Initial Term or at least three (3) months prior to the end of the Renewal Term.


3. Full time and efforts. Executive shall diligently and conscientiously de vote his full time, exclusive attention and best efforts to his duties under this contract.

4. Compensation.

(a) Commencing as of the Effective Date of this Agreement and until the Offering, the Company shall pay Executive base compensation for his services at the annual rate then in effect under Executive's existing arrangements with the Company (the "Base Compensation"). Commencing as of the effective date of the Offering, Executive's Base Compensation shall be $120,000 per year. The President of the Company in consultation with the Compensation Committee of the Board of the Company will review Executive's performance and determine any appropriate increases annually thereafter. Base Compensation shall be payable in biweekly or such other installments as shall be consistent with the Company's payroll procedures for its senior executives.

(b) In addition, Executive shall be eligible to earn an annual performance bonus (the "Annual Bonus") pursuant to criteria negotiated with the President and approved by the Compensation Committee of the Board of Directors of the Company. The Annual Bonus, if any, shall be paid within one-hundred twenty (120) days of the end of the relevant measuring period. It is expected that the Annual Bonus will be at a target level of not less than 25% nor more than 50% of the Base Compensation paid during such calendar year.

(c) RIG shall adopt as of the effectiveness of its Offering, and maintain for the benefit of Executive for as long as any options are outstanding, a Stock Option Plan (the "Stock Option Plan"). Under the Stock Option Plan, RIG will grant to Executive as of the effectiveness of the Offering an option to purchase such number of shares of RIG common stock as 12,849 units of RIGLP would be converted in the Offering. The exercise price of the options shall be the fair market value of such stock on the grant date (measured by the price of such stock determined at the pricing meeting of underwriters in connection with the Offering). Options granted to Executive under the Stock Option Plan may be non-qualified stock options or "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Such options shall vest: 25% upon the effectiveness of the Offering; 25% on December 31, 1998; 25% on December 31, 1999; and 25% on December 31, 2000.

(d) In the event that no Offering shall occur but the Company, OLD RIG or RIGLP shall consummate a Significant Equity Transaction during the term of this Agree ment, then immediately prior to the consummation of such transaction the Company, OLD RIG or RIGLP, as the case may be, shall grant to Executive options to purchase 40,000 shares of common stock of the Company, 12,849 shares of OLD RIG or 12,849 units of RIGLP, as the case may be, at a price per share or unit equivalent to the price being paid by the purchaser in such Significant Equity Transaction. Such options will vest as provided in
Section 4(c). For purposes of this clause (d), "Significant Equity Transaction" shall mean any equity funding of the

- 2 -

Company, OLD RIG or RIGLP, as the case may be, in which the purchaser invests at least $15 million in such entity or entities.

5. Benefits. Executive shall be entitled to participate in, and receive benefits from any insurance, medical, disability, vacation or pension plan of the Company for which Executive satisfies the generally applicable criteria for eligibility, and to other perquisites which may be in effect at any time during the term hereof that are generally available to senior executive officers of the Company.

6. Expense reimbursement. The Company shall reimburse Executive for all categories of expenses incurred in carrying out his duties under this Agreement that the Company's policies regard as reasonable and necessary. Executive shall present to the Company from time to time an itemized account of such expenses in any form required by the Company.

7. Termination without cause.

(a) By the Company. The Company may terminate this Agreement without cause upon sixty (60) days' written notice. In such an event
(i) all of Executive's unvested options due to vest within the next twelve (12) months will vest and (ii) Executive will, as severance and liquidated damages and in consideration of his execution of a complete and absolute release of the Company and its officers from any and all further claims, receive (A) on a monthly basis, as if he had not been terminated, all payments (other than bonus) he would have received for the greater of (x) the term remaining under the Agreement had he not been terminated or (y) six months, and (B) a pro rata share of any bonus based upon that portion of such calendar year during which Executive was employed.

(b) By Executive. Executive may without cause terminate this Agreement, by giving one hundred eighty (180) days' written notice during the Initial Term, or ninety (90) days' written notice during any Renewal Term, to the Company. In such event, at the sole discretion of the Company, Executive shall continue to render all services. Executive shall be paid the base compensation, accrue bonus and vest options as provided by Section 4 up to the date of termination, but shall not receive any salary or bonus payment thereafter nor shall any stock option that is not otherwise vested or nonforfeitable on the date of termination become vested or nonforfeitable on such date.

8. Termination after merger or acquisition. In the event of the merger of the Company or the acquisition, directly or indirectly, of all or substantially all of the Company's assets or a controlling interest in the voting shares of the Company by an unaffiliated party (a "Change of Control"), Executive may elect to treat that event as a termination without cause unless the new party: (a) extends to him a reasonable offer to (i) be retained by the Company in an executive position of responsibility, authority and compensation comparable in material respects (including location) to the position of Executive immediately prior to the Change of Control, (ii) retain all rights accorded under this Agreement and (iii) be afforded all privileges

- 3 -

accorded to other executives of the Company; and (b) in fact retains Executive in such capacity for at least twelve (12) months after the Change of Control. Executive acknowledges and agrees that the transactions described in the fourth recital shall not constitute a "Change of Control."

9. Termination for cause. The Company may terminate this Agreement (a) for cause at any time by notifying Executive in writing of such termination and the cause thereof or (b) in the event of Executive's death or prolonged disability; provided, however, that the only grounds constituting cause shall be: (i) Executive's gross negligence in the performance of his duties hereunder, intentional nonperformance or mis-performance of such duties, or refusal to abide by or comply with the reasonable, material and documented directives of the Board, his superior officers, or the Company's material policies and procedures (including without limitation the provisions of Section 10 hereof), which actions continue uncured for a period of at least thirty (30) days after receipt by Executive of written notice of the need to cure or cease;
(ii) Executive's willful dishonesty, fraud, or misconduct with respect to the business or affairs of the Company; (iii) Executive's indictment for, conviction of, or guilty or nolo contendere plea to, a felony; and (iv) Executive's abuse of alcohol or drugs (legal or illegal), other than legal drugs taken under the direction of a physician, that, in the Company's reasonable judgment, materially impairs Executive's ability to perform his duties hereunder. In any such event, Executive will forfeit all unvested options and all claims to bonuses not yet awarded, and will be paid through the date of the termination; provided, however, that in the event of termination for death or prolonged disability, all unvested options shall immediately vest.

10. Confidentiality, Invention and Non-Compete Agreement.

(a) During the term of this Agreement, and thereafter for the duration of the period, if any, that Executive continues to be employed by the Company and/or any other entity owned by or affiliated with the Company or on an "at will" basis, and thereafter for the Non-Competition Period (defined below), Executive shall not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, company, partnership, corporation, business, group, or other entity (each, a "Person"):

(i) engage, as an officer, director, shareholder, owner, partner, member, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant, advisor, or sales representative, in any business selling any products or services in direct competition with the Company in the United States, Canada, the United Kingdom, or other nations in which the Company is conducting or in which he was aware the Company had plans to conduct business within the eighteen (18) months following his termina tion (the "Territory"); provided, however, that the foregoing covenant shall not be deemed to prohibit Executive from acquiring as an investment not more than one percent (1%) of the capital stock of a competing business whose stock is traded on a national securities exchange or over-the-counter;

- 4 -

(ii) call upon any Person who is, at that time, within the Territory, an employee of the Company for the purpose or with the intent of enticing such employee away from or out of the employ of the Company;

(iii) call upon any Person who or that is, at that time, or has been, within one year prior to that time, a customer of the Company within the Territory for the purpose of soliciting or selling products or services in direct competition with the Company within the Territory; or

(iv) on Executive's own behalf or on behalf of any competitor, call upon any Person as a prospective acquisition candidate for an entity other than the Company or its affiliates who or that, during Executive's employment by the Company was, to Executive's knowledge, either called upon by the Company as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by the Company. Executive, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that the Company had called upon such candidate or made an acquisition analysis thereof.

(b) Executive acknowledges that during the course of his employment, he may develop and obtain access to trade secrets, proprietary software and other "confidential business information" of the Company, such as its software systems, sources of data, databases and other competitively sensitive information kept in confidence by the Company such as selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, and internal financial statements. Executive agrees to not use or disclose any trade secrets, proprietary software or confidential business information to which he is exposed or has access in the course of his employment with the Company, even if elements of any of them may belong to third parties, during his employment and for so long afterwards as the Company seeks to maintain as confidential the proprietary software, trade secrets or confidential business information, whether or not the software, trade secrets and confidential business information are in written or tangible form, except as required and authorized during the performance of Executive's duties for and with the Company. Executive agrees that, given the nature of the Company's business and business plans there will never come a time when disclosure of the Company's proprietary software, trade secrets or confidential information would not be seriously injurious to the Company.

(c) Executive acknowledges that he has been employed by the Company during its critical developmental and roll-out stages and that leaving the employ of the Company to join any business competitor would seriously hamper the business of the Company. Accordingly, Executive agrees that the Company shall be entitled to injunctive relief to prevent him from violating this Section 10, in addition to all remedies permitted by law, to enforce the provisions of this Agreement. Executive further acknowledges that his training, experience and technical skills are of such breadth that they can be employed to Executive's advantage in other areas which are not in direct competition with the business of the Company on the date of

- 5 -

termination of Executive's employment and consequently the foregoing obligations will not unreasonably impair Executive's ability to engage in business activity after the termination of Executive's employment.

(d) For purposes of this Section 10, the term "Company" shall mean the Company and each of its subsidiaries, predecessors in interest and successors; and the term "Non-Competition Period" shall mean the period commencing on the date hereof to and including the second anniversary of the date on which Executive ceases to be employed by the Company (provided, however, that the Non-Competition Period, during which the agreements and covenants of Executive made in this Section 10 shall be effective, shall be computed by excluding from such computation any time during which Executive is in violation of any provision of this Section 10).

(e) The covenants in this Section 10 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. If any provision of this Section 10 relating to the time period or geographic area of the restrictive covenants shall be declared by a court of competent jurisdiction to exceed the maximum time period or geographic area, as applicable, that such court deems reasonable and enforceable, said time period or geographic area shall be deemed to be, and thereafter shall become, the maximum time period or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination. Upon termination of this Agreement for any reason, the covenants specified in this Section 10 shall survive for the term specified herein.

(f) All of the covenants in this Section 10 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of such covenants.

11. Notices. All notices required or permitted to be given under this Agreement shall be given by certified mail, return receipt requested, to the parties at the following addresses or to such other addresses as either may designate in writing to the other party.

(a) If to the Company:

Andrew C. Florance Chief Executive Officer Realty Information Group 7475 Wisconsin Avenue Sixth Floor
Bethesda, Maryland 20814 Telefax: 301-718-2444

- 6 -

(b) If to Executive, to the address indicated below Executive's name on the signature page.

12. Arbitration. The parties agree that any dispute between the parties relating to this Agreement shall not be resolved in litigation, but instead shall be resolved in final, binding arbitration by a single arbitrator under the auspices of the American Arbitration Association ("AAA") in Washington, D.C. Any such arbitration shall be conducted in accordance to the AAA's Employment Dispute Resolution Procedures.

13. Waiver of Breach. The waiver by either party of a breach of any provisions of this Agreement by the other shall not operate or be construed as a waiver of any subsequent breach. A delay or failure by either party to exercise a right under this Agreement, or a partial or single exercise of that right, shall not constitute a waiver of that or any other right.

14. Governing Law. The Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware.

15. Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the Company and its respective successors and assigns but the rights and obligations of Executive are personal and may not be assigned or delegated without the Company's prior written consent. Notwithstanding the preceding sentence, OLD RIG shall be permitted to assign all of its obligations hereunder to RIG and such assignment shall be deemed to have occurred upon the effectiveness of the consolidation of OLD RIG and RIGLP with RIG (the "Assignment").

16. Counterparts. This Agreement, for the convenience of the parties, may be executed in any number of counterparts, all of which when taken together shall constitute one and the same Agreement.

17. Entire Agreement concerning Employment; Supremacy of Employment Agreement. This Agreement, together with Executive's arrangement with the Company concerning the forgiveness of debt relating to his purchase of units in RIGLP, constitutes the entire Agreement between the parties as to Executive's employment and compensation therefor and supersedes and replaces any and all agreements, written or oral, as to such matters. This Agreement may not be modified or amended orally, but only by an agreement in writing, signed by the party against whom enforcement of any waiver, change, modification, extension or discharge is sought. If there is any conflict with respect to Executive between the provisions of this Agreement and the provisions of either the bonus plan or the Stock Option Plan, as applicable, the provisions of this Agreement shall govern.

18. Amendments. This Agreement may be amended only in writing, signed by both parties.

In witness whereof, Company has by its appropriate officers, signed and affixed its seal and Executive has signed and sealed this Agreement, to be effective as of the last date noted below.

EXHIBIT

EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT is executed this 24 day of April, 1998, and effective as of January 1, 1998 (the "Effective Date"), by and between OLD RIG, Inc. ("OLD RIG" and, prior to the Assignment (defined below), the "Company"), a Delaware corporation which is the general partner of Realty Information Group, L.P. ("RIGLP"), a Delaware limited partnership, and Curtis M. Ricketts ("Executive").

WHEREAS, Executive has been heretofore employed by OLD RIG in the capacity of Senior Vice President of Sales and Marketing;

WHEREAS, OLD RIG desires to retain Executive in such capacity;

WHEREAS, Executive desires to remain employed in such capacity by OLD RIG upon the terms and conditions hereinafter set forth; and

WHEREAS, Executive and OLD RIG acknowledge that it is presently contem plated that, in connection with an initial public offering (the "Offering") of, or other significant transaction involving, the stock of Realty Information Group, Inc., a Delaware corporation ("RIG" and, after the Assignment (defined below), the "Company"), formerly known as Realty Information Group
(Delaware), Inc., (i) OLD RIG and RIGLP will be consolidated with RIG, and (ii)
this Employment Agreement will be automatically assigned to and assumed by RIG pursuant to Section 15 without further action by any party.

NOW, THEREFORE, the parties hereto, intending to be legally bound hereby, and in consideration of the mutual covenants herein contained, agree as follows:

1. Employment. The Company agrees to employ Executive at the Company's offices in the greater Washington metropolitan area, and Executive agrees to be so employed, in the capacity of Senior Vice President of Sales and Marketing. Executive shall perform such functions and undertake such responsibilities as are assigned from time to time by the President of the Company or the Board of Directors. The Company and Executive agree that this agreement terminates and replaces any previous employment agreements between Executive and the Company.

2. Term. The term of Executive's employment under this Agreement shall commence on the Effective Date and shall continue for the initial term set forth of two (2) years (the "Initial Term"), and for automatic and successive renewal terms of one (1) year each (each, a "Renewal Term" and collectively, the "Renewal Terms"), unless either the Company or Execu tive elects not to extend the term beyond the Initial Term or any Renewal Term (herein, the Initial Term or a Renewal Term is sometimes referred to as the "Current Term") and gives to the other party hereto written notice of termination at least six (6) months prior to the end of the Initial Term or at least three (3) months prior to the end of the Renewal Term.


3. Full time and efforts. Executive shall diligently and conscientiously de vote his full time, exclusive attention and best efforts to his duties under this contract.

4. Compensation.

(a) Commencing as of the Effective Date of this Agreement and until the Offering, the Company shall pay Executive base compensation for his services at the annual rate then in effect under Executive's existing arrangements with the Company (the "Base Compensation"), including his monthly bonus. Commencing as of the effective date of the Offering, Executive's Base Compensation shall be $110,000 per year. The President of the Company in consultation with the Compensation Committee of the Board of the Company will review Executive's performance and determine any appropriate increases annually thereafter. Base Compensation shall be payable in biweekly or such other installments as shall be consistent with the Company's payroll procedures for its senior executives.

(b) Commencing as of the effective date of the Offering, Executive shall be eligible to earn a quarterly performance bonus (the "Quarterly Bonus") pursuant to criteria negotiated quarterly with the President and approved annually by the Compensation Committee of the Board of Directors of the Company. The Quarterly Bonus, if any, shall be paid within thirty (30) days of then end of the relevant measuring period. It is expected that the Quarterly Bonus will be at a target level of not more than 100% of the Base Compensation paid during such calendar quarter.

(c) RIG shall adopt as of the effectiveness of its Offering, and main tain for the benefit of Executive for as long as any options are outstanding, a Stock Option Plan (the "Stock Option Plan"). Under the Stock Option Plan, RIG will grant to Executive as of the effectiveness of the Offering an option to purchase such number of shares of RIG common stock at the fair market value of such stock on the grant date as as 8,031 units of RIGLP would be converted in the Offering. The exercise price of the options shall be the fair market value of such stock on the grant date (measured by the price of such stock determined at the pricing meeting of underwriters in connection with the Offering). Options granted to Executive under the Stock Option Plan may be non-qualified stock options or "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Such options shall vest: 25% upon the effectiveness of the Offering; 25% on December 31, 1998; 25% on December 31, 1999; and 25% on December 31, 2000.

(d) In the event that no Offering shall occur but the Company, OLD RIG or RIGLP shall consummate a Significant Equity Transaction during the term of this Agree ment, then immediately prior to the consummation of such transaction the Company, OLD RIG or RIGLP, as the case may be, shall grant to Executive options to purchase 25,000 shares of common stock of the Company, 8,031 shares of OLD RIG or 8,031 units of RIGLP, as the case may be, at a price per share or unit equivalent to the price being paid by the purchaser in such Significant Equity Transaction. Such options will vest as provided in
Section 4(c). For purposes

- 2 -

of this clause (d), "Significant Equity Transaction" shall mean any equity funding of the Company, OLD RIG or RIGLP, as the case may be, in which the purchaser invests at least $15 million in such entity or entities.

5. Benefits. Executive shall be entitled to participate in, and receive benefits from any insurance, medical, disability, vacation or pension plan of the Company for which Executive satisfies the generally applicable criteria for eligibility, and to other perquisites which may be in effect at any time during the term hereof that are generally available to senior executive officers of the Company.

6. Expense reimbursement. The Company shall reimburse Executive for all categories of expenses incurred in carrying out his duties under this Agreement that the Company's policies regard as reasonable and necessary. Executive shall present to the Company from time to time an itemized account of such expenses in any form required by the Company.

7. Termination without cause.

(a) By the Company. The Company may terminate this Agreement without cause upon sixty (60) days' written notice. In such an event
(i) all of Executive's unvested options due to vest within the next twelve (12) months will vest and (ii) Executive will, as severance and liquidated damages and in consideration of his execution of a complete and absolute release of the Company and its officers from any and all further claims, receive (A) on a monthly basis, as if he had not been terminated, all payments (other than bonus) he would have received for the greater of (x) the term remaining under the Agreement had he not been terimated or (y) six months, and (B) a pro rata share of any bonus based upon that portion of the measuring period during which Executive was employed.

(b) By Executive. Executive may without cause terminate this Agreement, by giving one hundred eighty (180) days' written notice during the Initial Term, or ninety (90) days' written notice during any Renewal Term, to the Company. In such event, at the sole discretion of the Company, Executive shall continue to render all services. Executive shall be paid the base compensation, accrue bonus and vest options as provided by Section 4 up to the date of termination, but shall not receive any salary or bonus payment thereafter nor shall any stock option that is not otherwise vested or nonforfeitable on the date of termination become vested or nonforfeitable on such date.

8. Termination after merger or acquisition. In the event of the merger of the Company or the acquisition, directly or indirectly, of all or substantially all of the Company's assets or a controlling interest in the voting shares of the Company by an unaffiliated party (a "Change of Control"), Executive may elect to treat that event as a termination without cause unless the new party: (a) extends to him a reasonable offer to (i) be retained by the Company in an executive position of responsibility, authority and compensation comparable in material respects (including location) to the position of Executive immediately prior to the Change of

- 3 -

Control, (ii) retain all rights accorded under this Agreement and (iii) be afforded all privileges accorded to other executives of the Company; and (b) in fact retains Executive in such capacity for at least twelve (12) months after the Change of Control. Executive acknowledges and agrees that the transactions described in the fourth recital shall not constitute a "Change of Control."

9. Termination for cause. The Company may terminate this Agreement (a) for cause at any time by notifying Executive in writing of such termination and the cause thereof or (b) in the event of Executive's death or prolonged disability; provided, however, that the only grounds constituting cause shall be: (i) Executive's gross negligence in the performance of his duties hereunder, intentional nonperformance or mis-performance of such duties, or refusal to abide by or comply with the reasonable, material and documented directives of the Board, his superior officers, or the Company's material policies and procedures (including without limitation the provisions of Section 10 hereof), which actions continue uncured for a period of at least thirty (30) days after receipt by Executive of written notice of the need to cure or cease;
(ii) Executive's willful dishonesty, fraud, or misconduct with respect to the business or affairs of the Company; (iii) Executive's indictment for, conviction of, or guilty or nolo contendere plea to, a felony; and (iv) Executive's abuse of alcohol or drugs (legal or illegal), other than legal drugs taken under the direction of a physician, that, in the Company's reasonable judgment, materially impairs Executive's ability to perform his duties hereunder. In any such event, Executive will forfeit all unvested options and all claims to bonuses not yet awarded, and will be paid through the date of the termination; provided, however, that in the event of termination for death or prolonged disability, all unvested options shall immediately vest.

10. Confidentiality, Invention and Non-Compete Agreement.

(a) During the term of this Agreement, and thereafter for the duration of the period, if any, that Executive continues to be employed by the Company and/or any other entity owned by or affiliated with the Company or on an "at will" basis, and thereafter for the Non-Competition Period (defined below), Executive shall not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, company, partnership, corporation, business, group, or other entity (each, a "Person"):

(i) engage, as an officer, director, shareholder, owner, partner, member, joint venturer, or in a managerial capacity, whether as an employee, independent contractor, consultant, advisor, or sales representative, in any business selling any products or services in direct competition with the Company in the United States, Canada, the United Kingdom, or other nations in which the Company is conducting or in which he was aware the Company had plans to conduct business within the eighteen (18) months following his termination (the "Territory"); provided, however, that the foregoing covenant shall not be deemed to prohibit Executive from acquiring as an investment not more than one percent (1%) of the capital stock of a competing business whose stock is traded on a national securities exchange or over-the-counter;

- 4 -

(ii) call upon any Person who is, at that time, within the Territory, an employee of the Company for the purpose or with the intent of enticing such employee away from or out of the employ of the Company;

(iii) call upon any Person who or that is, at that time, or has been, within one year prior to that time, a customer of the Company within the Territory for the purpose of soliciting or selling products or services in direct competition with the Company within the Territory; or

(iv) on Executive's own behalf or on behalf of any competitor, call upon any Person as a prospective acquisition candidate for an entity other than the Company or its affiliates who or that, during Executive's employment by the Company was, to Executive's knowledge, either called upon by the Company as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by the Company. Executive, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that the Company had called upon such candidate or made an acquisition analysis thereof.

(b) Executive acknowledges that during the course of his employment, he may develop and obtain access to trade secrets, proprietary software and other "confidential business information" of the Company, such as its software systems, sources of data, databases and other competitively sensitive information kept in confidence by the Company such as selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, and internal financial statements. Executive agrees to not use or disclose any trade secrets, proprietary software or confidential business information to which he is exposed or has access in the course of his employment with the Company, even if elements of any of them may belong to third parties, during his employment and for so long afterwards as the Company seeks to maintain as confidential the proprietary software, trade secrets or confidential business information, whether or not the software, trade secrets and confidential business information are in written or tangible form, except as required and authorized during the performance of Executive's duties for and with the Company. Executive agrees that, given the nature of the Company's business and business plans there will never come a time when disclosure of the Company's proprietary software, trade secrets or confidential information would not be seriously injurious to the Company.

(c) Executive acknowledges that he has been employed by the Company during its critical developmental and roll-out stages and that leaving the employ of the Company to join any business competitor would seriously hamper the business of the Company. Accordingly, Executive agrees that the Company shall be entitled to injunctive relief to prevent him from violating this
Section 10, in addition to all remedies permitted by law, to enforce the provisions of this Agreement. Executive further acknowledges that his training, experience and technical skills are of such breadth that they can be employed to Executive's advantage in other areas which are not in direct competition with the business of the Company on the date of

- 5 -

termination of Executive's employment and consequently the foregoing obligations will not unreasonably impair Executive's ability to engage in business activity after the termination of Executive's employment.

(d) For purposes of this Section 10, the term "Company"shall mean the Company and each of its subsidiaries, predecessors in interest and successors; and the term "Non-Competition Period" shall mean the period commencing on the date hereof to and including the second anniversary of the date on which Executive ceases to be employed by the Company (provided, however, that the Non-Competition Period, during which the agreements and covenants of Executive made in this Section 10 shall be effective, shall be computed by excluding from such computation any time during which Executive is in violation of any provision of this Section 10).

(e) The covenants in this Section 10 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. If any provision of this Section 10 relating to the time period or geographic area of the restrictive covenants shall be declared by a court of competent jurisdiction to exceed the maximum time period or geographic area, as applicable, that such court deems reasonable and enforceable, said time period or geographic area shall be deemed to be, and thereafter shall become, the maximum time period or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination. Upon termination of this Agreement for any reason, the covenants specified in this Section 10 shall survive for the term specified herein.

(f) All of the covenants in this Section 10 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of such covenants.

EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT dated this 13th day of March, 1998, and effective as of the Effective Date (defined below), by and between Realty Information Group, Inc., a Delaware corporation (formerly known as "Realty Information Group, Inc. (Delaware), Inc.") (the "Company"), Jamison Research Incorporated ("JRI") and Henry D. Jamison, IV (the "Executive").

In connection with the Company's acquisition of all the shares of JRI the Company desires to employ the Executive to devote full time to the business of the Company and or JRI, and the Executive desires to be so employed.

The parties agree as follows:

1. EMPLOYMENT. The Company agrees to employ the Executive, and the Executive agrees to be so employed, in the capacity of Vice President-Consulting Services and President of an entity likely to be named Jamison Reports ("JR") , located in Atlanta, Georgia. The Executive shall perform such functions and undertake such responsibilities as are assigned from time to time by the President of the Company or the Board of Directors. The Executive's employment shall be for a term of three years commencing on the Effective Date of this Agreement.

2. TERMINATION OF PRIOR EMPLOYMENT AGREEMENTS. The Company and the Executive agree that this agreement terminates and replaces any previous employment agreements between the Executive and JRI including any resolutions or oral understandings that might be construed to be a part of any such agreement, subject to agreement between the Company, JRI and the Executive concerning the settlement as Effective Date, of any amounts that may then be due and owing under and in accordance with any such agreements. Upon that settlement, all other agreements between the parties concerning employment are hereby terminated and of no further force and effect, all without cost or charge to JRI or the Company.

3. FULL TIME AND EFFORTS. Except as otherwise provided in this
Section 3, the Executive shall diligently and conscientiously devote his full time, exclusive attention and best efforts to his duties as the Company's Vice President-Consulting Services and President of JC. However, the Executive shall be entitled to devote a reasonable amount of time to service with religious, charitable and other non-profit organizations, to service on advisory boards and boards of directors of trade associations, and to such other business entities that do not compete with the business of the Company, to the extent that the cumulative burden of such service does not, in the reasonable view of the President of the Company, interfere with the Executive's primary responsibility to the Company. The Executive shall keep the President of the Company apprised of the fact and demands of each such activity.

4. COMPENSATION. Commencing as of the Effective Date of this Agreement, the Company shall pay the Executive base compensation for his services at an annual rate of one


hundred thirty-five thousand dollars ($135,000) for the first full year. For the second and third years, the Company shall pay the Executive base compensation for his services at an annual rate of no less one hundred thirty-five thousand dollars ($135,000), and the President of the Company in consultation with the Compensation Committee of the Board of the company, will review the Executive's performance and determine any appropriate increases. This base compensation shall be paid in equal bi-weekly installments. In addition, the Executive shall be eligible to earn an annual performance bonus (the "Annual Bonus") of up to two hundred percent (200%) of his base salary pursuant to criteria negotiated with the President and approved by the the Compensation Committee of the Board of Directors of the Company. For the first year, the criteria for the Annual Bonus will be that set forth in Appendix A to this Agreement. The Annual Bonus, if any, shall be paid within 120 days of each anniversary of the Effective Date hereof.

5. BENEFITS. The Executive shall be entitled to participate in, and receive benefits from any insurance, medical, disability or pension plan of the Company, and to other perquisites which may be in effect at any time during the term hereof that are generally available to senior executive officers of the Company. Copies of the current version of those policies are attached as Schedule 5 to this Agreement.

6. EXPENSE REIMBURSEMENT. The Company shall reimburse the Executive for all categories of reasonable and necessary expenses incurred in carrying out his duties under this Agreement that are reimbursed to any other Vice President of the Company. The Executive shall present to the Company from time to time an itemized account of such expenses in any form required by the Company. Such expenses shall be reimbursed within 30 days of submission of appropriate documentation.

7. TERMINATION WITHOUT CAUSE.

(a) BY THE COMPANY. After the second anniversary of the Effective Date of this Agreement, the Company may terminate this Agreement without cause upon sixty (60) days written notice, however in that event (i) all of the Executive's unvested options due to vest within the six months will vest and (ii) the Executive will continue to receive over the term of this agreement, as if he had not been terminated, all payments he would have received had he not been terminated (and a pro rata share of any bonus, which shall be based upon the number of days since the last anniversary, and the number remaining until the next anniversary, of the Effective Date hereof) as severance and as liquidated damages, subject to and in consideration of his execution of a complete and absolute release of the Company and its officers and directors from any and all further claims relating to his employment hereunder.

(b) BY THE EXECUTIVE. After the second anniversary of the Effective Date of this Agreement, the Executive may without cause terminate this Agreement, by giving one hundred twenty (120) days' written notice to the Company. In such event, at the sole discretion of the Company, the Executive shall continue to render all services and shall be paid

-2-

the base compensation as provided by Section 4 up to the date of termination, but shall not receive any bonus payment thereafter nor shall any stock option that is not otherwise vested or nonforfeitable on the date of termination become vested or nonforfeitable on such date.

8. TERMINATION AFTER MERGER OR ACQUISITION. In the event of the merger of the Company or the acquisition, directly or indirectly, of all or substantially all of the Company's assets or a controlling interest in the voting shares of the Company by an unaffiliated party (a AChange of Control"), the Executive may elect to treat that event as a termination without cause unless the new party extends to him a reasonable offer to: (a) be retained by the Company in an executive position of responsibility, authority and compensation comparable in material respects (including location) to the position of the Executive immediately prior to the Change of Control; (b) retain all rights accorded under this Agreement; and (c) be afforded all privileges accorded to other executives of the Company. If the Executive elects to be terminated pursuant to such a Change of Control, then on the date the termination becomes effective, any portion of any stock option awarded to the Executive pursuant to any stock option plan not already vested shall become fully vested.

9. TERMINATION FOR CAUSE. The Company may terminate this Agreement for cause at any time by notifying the Executive of such termination and the cause thereof; provided, however, that the only grounds constituting cause shall be: (a) the Executive's death, (b) the Executive's prolonged disability, (c) the Executive's gross negligence in the performance of his duties hereunder, intentional nonperformance or mis-performance of such duties, or refusal to abide by or comply with the reasonable and documented directives of the Board, his superior officers, or the Company's material policies and procedures, which actions continue for a period of at least ten (10) days after receipt by Executive of written notice of the need to cure or cease; (d) the Executive's willful dishonesty, fraud, or misconduct with respect to the business or affairs of the Company and that, in the judgment of the Company, materially and adversely affects the operations or reputation of the Company;
(e) the Executive's conviction of a felony involving moral turpitude; and (f) the Executive's abuse of alcohol or drugs (legal or illegal) that, in the Company's judgment, materially impairs the Executive's ability to perform his duties hereunder. In any such event, the Executive will forfeit all unvested options, all claims to bonuses not yet awarded and will be paid through the date of the termination.

10. CONFIDENTIALITY, INVENTION AND NON-COMPETE AGREEMENT.

(a) During the term of this Agreement, and thereafter for the duration of the period, if any, that the Executive continues to be employed by the Company and/or any other entity owned by or affiliated with the Company or on an "at will" basis, and thereafter for the Non-Competition Period (defined below), the Executive shall not, directly or indirectly, for himself or on behalf of or in conjunction with any other person, company, partnership, corporation, business, group, or other entity (each, a " Person"):

(i) engage, as an officer, director, shareholder, owner, partner, member, joint venturer, or in a managerial capacity, whether as an employee, independent

-3-

contractor, consultant, advisor, or sales representative, in any business selling any products or services in direct competition with the Company in any business selling any products or services in direct competition with Parent, in the United States, Canada, the United Kingdom, or other nations in which the Company is conducting or in which he was aware the Company had plans to conduct business within the twelve months following his termination (the "Territory"); provided, however, that the foregoing covenant shall not be deemed to prohibit the Executive from acquiring as an investment not more than one percent (1%) of the capital stock of a competing business whose stock is traded on a national securities exchange or over-the-counter;

(ii) call upon any Person who is, at that time, within the Territory, an employee of the Company for the purpose or with the intent of enticing such employee away from or out of the employ of the Company;

(iii) call upon any Person who or that is, at that time, or has been, within one year prior to that time, a customer of the Company within the Territory for the purpose of soliciting or selling products or services in direct competition with the Company within the Territory; or

(iv) on the Executive's own behalf or on behalf of any competitor, call upon any Person as a prospective acquisition candidate for an entity other than the Company or its affiliates who or that, during the Executive's employment by the Company was, to the Executive's knowledge, either called upon by the Company as a prospective acquisition candidate or was the subject of an acquisition analysis conducted by the Company. The Executive, to the extent lacking the knowledge described in the preceding sentence, shall immediately cease all contact with any prospective acquisition candidate upon being informed that the Company had called upon such candidate or made an acquisition analysis thereof.

(b) The Executive acknowledges that during the course of his employment, he may develop and obtain access to trade secrets, proprietary software and other "confidential business information" of the Company, such as its software systems, sources of data, databases and other competitively sensitive information kept in confidence by the Company such as selling and pricing information and procedures, research methodologies, customer lists, business and marketing plans, and internal financial statements. The Executive agrees to not use or disclose any trade secrets, proprietary software or confidential business information to which he is exposed or has access in the course of his employment with the Company, even if elements of any of them may belong to third parties, during his employment and for so long afterwards as the Company seeks to maintain as confidential the proprietary software, trade secrets or confidential business information, whether or not the software, trade secrets and confidential business information are in written or tangible form, except as required and authorized during the performance of the Executive's duties for and with the Company. The Executive agrees that, given the nature of the Company's business and business plans twenty-four (24) months is a reasonable period during which disclosure of proprietary software, trade secrets or confidential information would be injurious to the Company; and that there will never come a time when

-4-

disclosure of the Company's proprietary software would not be seriously injurious to the Company.

(c) The Executive acknowledges that he has been employed by the Company during its critical developmental and roll-out stages and that leaving the employ of the Company to join any business competitor would seriously hamper the business of the Company. Accordingly, the Executive agrees that the Company shall be entitled to injunctive relief to prevent him from violating this
Section 10, in addition to all remedies permitted by law, to enforce the provisions of this Agreement. The Executive further acknowledges that his training, experience and technical skills are of such breadth that they can be employed to the Executive's advantage in other areas which are not in direct competition with the business of the Company on the date of termination of the Executive's employment and consequently the foregoing obligations will not unreasonably impair the Executive's ability to engage in business activity after the termination of the Executive's employment.

(d) For purposes of this Section 10, the term "Company" shall mean the Company and each of its subsidiaries and predecessors in interest; and the term "Non-Competition Period" shall mean the period commencing on the Effective Date to and including the second anniversary of the date on which the Executive ceases to be employed by the Company (provided, however, that the Non-Competition Period, during which the agreements and covenants of the Executive made in this Section 10 shall be effective, shall be computed by excluding from such computation any time during which the Executive is in violation of any provision of this Section 10).

(e) The covenants in this Section 10 are severable and separate, and the unenforceability of any specific covenant shall not affect the provisions of any other covenant. If any provision of this Section 10 relating to the time period or geographic area of the restrictive covenants shall be declared by a court of competent jurisdiction to exceed the maximum time period or geographic area, as applicable, that such court deems reasonable and enforceable, said time period or geographic area shall be deemed to be, and thereafter shall become, the maximum time period or largest geographic area that such court deems reasonable and enforceable and this Agreement shall automatically be considered to have been amended and revised to reflect such determination.

(f) All of the covenants in this Section 10 shall be construed as an agreement independent of any other provision in this Agreement, and the existence of any claim or cause of action of the Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of such covenants.
