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 eight6.9 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.122,000
buildings. The Combined Database also contains detailed information on 120,00076,000 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 nine7 of the ten10 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.Advertising. 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
specialized reports and 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 1,9001,300
clients, including leaders of the commercial real estate industry such as CB
Commercial Real Estate Group, Inc., Grubb & Ellis, 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:

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.RIGLP. 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.

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

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, theThe Company is expandingintends to
expand its market and product line withthrough acquisitions of 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 business

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 2,700,0002,500,000 shares
offered hereby, a total of

5,911,6355,802,497 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 2,659,7002,509,747 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%25.6% 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 CompanyCommon 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.Klein. 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

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$7.21 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 2,109,0912,500,000
shares of Common Stock in the Offering are estimated to be $23.2$25.0 million,
assuming an initial public Offering price of $11.00$10.00 per share. Net proceeds
after deducting underwriting discounts and commissions and other expenses of the
Offering will be approximately $20.6$22.2 million ($23.424.5 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 (through acquisitions and internally generated growth) 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$1,650,000
(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), and (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.

CAPITALIZATION

The following table sets forth the capitalization of the Company as of
March 31, 1998: (i) on an actual basis, (ii) on a pro forma basis to reflect the
Jamison Acquisition and the issuance of shares of Common Stock in connection
therewith and (iii)(ii) on such pro forma basis as

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 3.1133.03 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$767,000 or $0.49$.13 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
6,820,7265,754,017 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 2,109,0912,500,000 shares offered hereby at the assumed initial offering price of
$11.00$10.00 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$23.0 million or
$2.68$2.79 per share. This represents an immediate increase in pro forma net tangible
book value of $2.19$2.66 per share to existing stockholders and immediate dilution in
pro forma net tangible book value of $8.32$7.21 per share to purchasers of Common
Stock in the Offering, as illustrated in the following table:

The following table sets forth, as of March 31, 1998, the number of shares
of Common Stock issued to existing stockholders of the Company and the total
consideration (including the fair value of the shares of Common Stock issued to
the stockholders of Jamison) and the average price per share paid to the Company for such

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

2019

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.

(2) Earnings before interest, taxes, depreciation and amortization ("EBITDA")
shown here excludes allocation of the Company's general and administrative
expenses. 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.

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.

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.

BUSINESS

OVERVIEW

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, 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 eight6.9
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.122,000
buildings. The Combined Database also contains detailed information on 120,00076,000 tenants and
13,00014,000 buildings for sale (with an aggregate asking price in excess of $15$15.0
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 nine7 of the ten10 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. 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
specialized reports and 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-

pendentindependent
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 eight6.9 billion square feet of
office and industrial inventory and more than 120,00076,000 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.

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 nineseven 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 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 eight6.9 billion square feet of office and industrial
inventory in more than 150,000122,000 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 120,00076,000 tenants and thousands of lease transactions.

The Combined Database also includes 124,000105,000 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 133over 95 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 140,000122,000 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.

30
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-sizemid-

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

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
and the General Services Administration and Department of Commerce.Administration.

The Combined Company has over 1,9001,300 clients, including leaders of the commercial
real estate industry such as CB Commercial Real Estate Group, Inc., Grubb &
Ellis, 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 developedis developing sales and marketing methods that achieve
meaningful penetration in a new market within three months of entry. The Company
hasis creating 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.

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. Jamison Research,
Inc. ("Jamison") is a commercial real estate information provider based in
Atlanta that expanded into the Dallas region in 1995. On February 17, 1998, the
Company entered into an agreement to acquire Jamison that was contingent on the
consummation of the Offering. The parties subsequently terminated this agreement
because of accounting issues associated with the concurrent purchase of Jamison
and the consolidation of RIGINC and RIGLP with the Company, and have no
agreement or understanding on whether to effect a merger or acquisition after
the Offering. 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

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, Canada and Canadathe United Kingdom 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 133over 95 researchers and 3021 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.

FACILITIES

The Company's corporate offices occupy approximately 21,000 square feet in
Bethesda, Maryland, under leases and subleases expiring June 30, 2000. 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.Philadelphia. Aggregate lease payments for the Combined
Company for the year ended December 31, 1997 were approximately $895,000.$766,000.

LEGAL PROCEEDINGS

The Company has been involved from time to time in lawsuits incidental to
its business. The Company is not currently subject to, and none of its
properties is subject to, any material legal proceedings.

Curtis M. Ricketts. In April 1998, the Company entered into an employment
agreement with Curtis M. Ricketts, its Vice President-Sales, which agreement is
effective as of January 1, 1998. Mr. Ricketts' employment agreement provides for
continuation of Mr. Rickett's current base salary, which base salary increases
to $110,000 upon the initial public offering. Mr. Ricketts is entitled to a
quarterly bonus award up to 100% of his base salary during the quarter based
upon achievement of certain performance objectives to be negotiated with the
Chief Executive Officer and the Compensation Committee, and to participate in
and receive benefits from any insurance, medical, disability or pension plan
generally made available to the senior executive officers of the Company. In
addition, Mr. Ricketts' employment agreement provides for an initial grant of an
option for 25,000 shares of Common Stock to Mr. Ricketts with an exercise price

public offering and one-fourth on each of December 31, 1998, 1999 and 2000. Mr.
Ricketts' employment agreement is for an initial term of two years and is
automatically renewable for additional, successive one-year terms, unless
terminated or not renewed by the Company or Mr. Ricketts. In the event of a
termination of employment by the Company without cause, Mr. Ricketts is entitled
to receive his base salary for whatever period is remaining under the employment
agreement or six months (whichever is greater), a prorated share of his bonus
for the year in which the termination occurred, and all of his unvested options
that would have vested within twelve months immediately vest. Pursuant to his
agreement, Mr. Ricketts is subject to a two-year covenant not to compete with
the Company similar to that described with respect to Mr. Florance. Applicable
law may limit the term or scope of the covenant not to compete.

Henry D. Jamison, IV. In March 1998, the Company entered into an employment
agreement with Henry D. Jamison, IV, to serve as a Vice President of the Company
and as president of a division of the Company likely to be named Jamison
Reports. This employment agreement does not become effective unless and until
the acquisition of Jamison is consummated. Mr. Jamison's employment agreement
provides for a base salary of $135,000. Mr. Jamison is entitled to an annual
performance bonus based on criteria negotiated with the Company's President and
to participate in and receive benefits from any insurance, medical, disability
or pension plan generally available to senior executive officers of the Company.
Mr. Jamison's employment agreement is not terminable by either party without
cause until after the second anniversary. After that point, the Company will be
permitted to terminate the agreement without cause upon sixty (60) days written
notice. In the event of a termination of employment by the Company without
cause, he 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 all of Mr. Jamison's unvested options due to vest within the six
months will vest immediately. This agreement is due to expire three years after
its execution. See "Certain Transactions." Pursuant to his agreement, Mr.
Jamison is subject to a two-year covenant not to compete with the Company
similar to that described with respect to Mr. Florance. Applicable law may limit
the term or scope of the covenant not to compete.

EMPLOYEE BENEFIT PLANS

The Company currently anticipates that its Board of Directors will adopt
the Stock Option Plan at or prior to consummation of the Offering and that such
plan will be submitted for stockholder approval at the next annual meeting of
stockholders. The Company has reserved 1,450,000 shares of Common Stock for
issuance under the Stock Option Plan and expects that approximately 350,000
options will be granted as part of this process, subject to approval of the
Compensation Committee. Unless terminated sooner by the Board of Directors, the
Stock Option Plan will terminate in April 2006.

The Stock Option Plan will be administered by the Compensation Committee of
the Board of Directors. The Committee will have the authority and discretion,
subject to the provisions of the Stock Option Plan, to select persons to whom
options will be granted, to designate the number of shares to be covered by
options, to specify the type of consideration to be paid to the Company, and to
establish all other terms and conditions of each stock option.

The Stock Option Plan will provide for the grant of stock options to
officers and employees of the Company or its subsidiaries. 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.

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 923,478898,856 shares of Common Stock of the Company at an
effective price per share of $3.36)$3.45). 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 266,630259,521 shares of Common Stock of the Company at an effective price per share
of $3.97)$4.08). 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(94,312 shares of Common Stock of the Company at an effective price per
share of $3.36,$3.45, 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 terminateterminated in JuneMay 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, 46,69545,450 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 729,847710,388 shares of Common Stock of the Company at
an effective price per share of $3.97)$4.08). 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 188,754183,721

shares of the 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

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.

(v) indemnification by the Company and Jamison Selling Stockholders for breaches
of their representations, warranties and covenants.

February 28,May 31, 1998, the Company had no outstanding shares of Common Stock. Following

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

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 8,929,8178,302,497
outstanding shares of Common Stock. Of these shares, the 2,700,0002,500,000 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). 6,229,8175,802,497 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-

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 90,00083,000 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 409,297398,384 shares, of which options to purchase
256,128249,299 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 2,659,7002,509,747 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 ................................ 2,700,0002,500,000
=========

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.

4845

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 729,847710,388 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%25.6% 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.

1997 and for each of the three years in the period ended December 31, 1997; the
financial statements of RIGINC at December 31, 1996 and 1997 and for each of the

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 3.1133.03 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 and 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

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.

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.predecessors. 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
46,69545,450 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. The fair value
of each warrant 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 1 year.
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)(b) 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)(c) 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.

Offering adjustment:

(f)(d) Assuming an initial public offering price of $11.00$10.00 per share,
the proceeds of the initial public offering amounting to
approximately $20,600,000,$22,200,000, net of expenses of the offering
estimated at $950,000,$1,050,000, are used initially to eliminate debts of
RIGLP RIGINC and Jamison,RIGINC including the line of credit and subordinated
debt to a partner advances
from stockholders, and long term debt.of RIGLP. 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,$1,650,000 resulting in an increase in cash of the
Company from the Offering, after repayment of debt, of
$18,779,198.$20,550,000.

4. WEIGHTED AVERAGE SHARES OUTSTANDING

Includes 1,899,015 shares or units of the Company's predecessors
converted at a rate of 3.1133.03 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, 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

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 97-2SOP97-2 was not material in the financial statements of RIGLP. In March
1998, AcSEC issued SOP 98-4SOP98-4 which defers for one year the implementation of
certain previsionprovision of SOP 97-2. The issuance of SOP 98-4 had no effect on RIGLP.

Pro Forma Loss Per Share

Pro Forma loss per share information is presented as if the Partnership had
operated as a C-CorprationC-Corporation for all periosperiods presented. In February 1997, the
FinacialFinancial Accounting Standards Board issued Statement No. 128, Earnings per
Share."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.

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.

At December 31, 1997, future minimum lease payments under operating leases
are as follows:

1998 ........................ $ 869,100
1999 ........................ 738,100
2000 ........................ 460,000
2001 ........................ 90,600
2002 and thereafter ......... 70,000
----------
$ 2,227,800
===========

Rent expense was approximately $201,000, $525,000 and $766,000 and rental
income was approximately $23,000, $46,000 and $0 for the years ended December
31, 1995, 1996 and 1997, respectively.

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.

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.

Unit option activity was as follows:

Outstanding at December 31, 1994 ......... 26,000 $ 5.00 $ 5.00

=======
Exercisable at December 31, 1995 ......... 21,870 $ 8.46
=======

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.

Employee 401(k) Plan

Effective January 1, 1997, RIGLP established a 401(k) Plan (the "401(k)")
to provide retirement benefits for eligible employees. The 401(k) provides for
tax deferred contributions of between 1% and 15% of employees' salaries, limited
to a maximum annual amount as established by the Internal Revenue Service. RIGLP
matches 25% of employee contributions up to a maximum of 6% of total
compensation. Amounts contributed to the 401(k) by RIGLP to match employee
contributions were $27,808 in 1997.

10. MANAGEMENT PLANS

Related to a filing of a Registration Statement on Form S-1 by Realty
Information Group, Inc., a newly formed successor corporation, RIGLP anticipates
entering into an Agreement and Plan of Contribution ("Agreement") by and among
Realty Information Group, Inc., RIGLP and RIGINC, to contribute all of RIGLP's
outstanding partnership units (other than those held by the general partner) to
Realty Information Group, Inc. in exchange for common stock of Realty

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

Reclassifications

Certain amounts in the 1995 and 1996 financial statements have been
reclassified to conform with the 1997 presentation. In addition, on May 23,
1996, RIGINC was re-incorporated as a Delaware corporation, changing authorized
common stock to 1,500,000 shares at a par value of $.01 per share. Accordingly,
common stock and additional paid-in capital accounts have been reclassified to
reflect this change for all periods presented.

Use of 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

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. 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, 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. 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

F-28

OLD RIG, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

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 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 earning 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.

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, RIGINC had no item of comprehensive income and,
according, the Statement does not apply.

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 1988. 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.

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.

OLD RIG, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

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

Reclassifications

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

Use of 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

Capitalized Product Development Costs

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

Concentration of Credit Risk

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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

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, icluding the three
months ended March 31, 1998, RIGINC had no items of Comprehensive Income and,
accordingly, the Statement does not apply.

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.

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.

Index 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

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.

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.

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", 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.

3. COMMITMENTS

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
2000 ........................ 145,100
2001 ........................ 143,300
2002 and thereafter ......... --
---------
$ 604,600
=========

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.

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.

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 15. RECENT SALES OF UNREGISTERED SECURITIES

In the three years preceding the filing of this Registration Statement, the
Company sold the following securities that were not registered under the

and (ii) 1,000 limited partnership units to Horowitz Limited Partnership I in

from registration under Section 4(2) of the Securities Act.

4. On June 30, 1996, RIGLP issued to David Schaffel, a vice president of

Scheffel received a loan of $50,000 from the partnership, which was utilized for
the payment of the exercise price. Such loan is being forgiven over a three year
period. These units were purchased for investment purposes. The issuance of such
units was effected in reliance on the exemption from registration under Section
4(2) of the Securities Act and Rule 701.

5. During June through October 1996, RIGINC issued 45,749, 12,200, 871,

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.
