resulted in record sales and continued profitability in

our established markets. We expect new markets in

which we are currently investing to reach profitability

within the next 12 to 18 months.

We have built our business model on recurring rev-

enues derived from subscription fees for our products.

This model is scalable and provides a solid foundation

as we seek to build the Internet marketplace for the

commercial real estate industry.

While we have experienced significant growth to-

date, there remain tremendous opportunities for our

current products as we continue to rollout product

offerings nationally to new and existing markets. We

are targeting new customer segments in existing mar-

kets and have entered entirely new markets this year.

We have seen our customer base grow substantially

year to over 3,600 firms at year-end, with over 7,500

Our database encompasses several distinct silos of

real estate information and fills terabytes of storage

capacity on our servers. CoStar has always applied its

technological expertise to most effectively deliver our

content to our customers.

Today, the Internet widely expands CoStar’s reach

and provides unparalleled flexibility for product 

development. We can intelligently integrate data from

distinct sectors of information, deliver it more quickly

decrease the cost of due diligence and ultimately,

increase the value of their real estate transactions.

(In this report, the words “we”, “our”, “us”, “CoStar” or “the Company” refer to CoStar Group, Inc. and its
subsidiaries.  This  report  also  refers  to  our Web  site, but  information  contained  on  that  site  is  not  part  of  this
report.)

CoStar Group, Inc., a Delaware corporation incorporated in 1998 to succeed its predecessor companies, is the
nation’s largest provider of information services to the commercial real estate industry. Through internal develop-
ment, extensive research and strategic acquisitions over 13 years, CoStar has compiled a comprehensive propri-
etary database that, as of March 22, 2000, covered 54 markets and tracked leasing and sales transactions for over
15 billion square feet of commercial real estate and approximately 900,000 tenants. CoStar delivers its content to
customers through eight distinct products and services. Our wide array of digital service offerings includes a leas-
ing marketplace, a selling marketplace, sales comparable information, decision support, contact management, ten-
ant  information, property  marketing, and  industry  news.  In  1999, the  Company  made  significant  progress  in
moving its business model to the Internet. Substantially all our current services are digitally delivered and most of
our clients receive information over the Internet. The advent of the Internet allows CoStar to integrate data from
distinct product areas, deliver it more quickly to customers and allows our clients to increase their efficiencies,
decrease costs of conducting business and ultimately, increase transaction values. Today, we are creating a digital
marketplace where the commercial real estate industry and related businesses can continuously interact and easily
facilitate transactions over the Internet due to efficient exchange of accurate and standardized information sup-
plied by CoStar.

We have three assets that provide a unique foundation for this marketplace: the most comprehensive, propri-
etary, national database in the industry; the largest research department in the industry; and what we believe is the
largest number of participating organizations. Our database has been constructed over more than a decade by a
research  department  that  makes  updates  daily  to  our  database  throughout  the  year.  In  addition  to  our  internal
efforts, we have obtained and assimilated over 50 proprietary databases. The database now contains information
on over $500 billion in lease transactions and covers more over $40 billion in properties for sale.

Industry Overview

We believe that the market for commercial real estate information is vast based on the variety, volume, and
value of transactions related to commercial real estate. To facilitate transactions, industry participants must have
extensive, accurate, and current information. Members of the commercial real estate and related business commu-
nity require daily access to current data such as rental rates, vacancy rates, tenant movements, supply, new con-
struction, absorption  rates, and  other  important  market  developments  to  carry  out  their  businesses  effectively.
Such data collection is time-consuming, as shown by a 1996 study we commissioned, which found that commer-
cial real estate professionals spent 40% of their workday collecting and analyzing information on the real estate
market.  Therefore, there  is  a  strong  need  for  an  efficient  marketplace, where  members  of  the  commercial  real
estate and related business community can exchange information, evaluate opportunities using national standard-
ized data, and interact with each other on a continuous basis.

A  large  number  of  parties  involved  in  the  commercial  real  estate  and  related  business  community  require

extensive information, including:

• Sales and leasing brokers

• Property owners

• Property management firms

• Design and construction firms

• Real estate developers

• Real estate investment trusts
• Investment banks

• Commercial banks

• Investors and asset managers

• Government agencies

• Mortgage-backed security issuers

• Appraisers

• Media

• Tenant vendors

• Building services vendors
• Communications providers

• Insurance companies

• Institutional advisors

The commercial real estate and related business community generally operates in an inefficient marketplace
because  of  the  fragmented  approach  to  gathering  and  exchanging  information  within  the  marketplace. Various
organizations, including  hundreds  of  brokerage  firms, directory  publishers, and  local  research  companies, have
attempted to collect data on specific markets and to develop software to analyze the information they had inde-
pendently gathered. This fragmented approach has resulted in duplication of effort in the collection and analysis
of information, excessive internal cost, non-standardized data with varying degrees of accuracy and comprehen-
siveness, and a large information gap.

The creation of an efficient digital marketplace for commercial real estate will require an infrastructure of a
national, standardized database, accurate and comprehensive research capabilities, and intensive, real-time partic-
ipant interaction. The Internet can help maximize interaction among participants in a marketplace. The Internet
has emerged as a mass communications and commerce medium enabling millions of people worldwide to share
information, create community among individuals with similar interests, and conduct business electronically. In
addition  to  its  emergence  as  a  mass  communications  medium, the  Internet  has  features  and  functions  that  are
unavailable in traditional media, which enable users to:

• retrieve enormous amounts of information at low cost and without geographic limitation;

• access dynamic and interactive content on a real-time basis; and

• communicate and interact instantaneously with a single individual or with large groups of users.

CoStar’s Comprehensive, National Database

CoStar has spent 13 years building and acquiring a proprietary database of commercial real estate informa-
tion, including  leasing, sales, tenants, demand  statistics  and  digital  images  The  completed  acquisition  of
COMPS.COM, Inc. (“Comps”) in February 2000 significantly increased the resources in our database. Comps has
spent 18 years building a proprietary database of commercial real estate sales transactions.

Combined, as of March 22, 2000, our proprietary database contains:

• more than 15 billion square feet of U.S. commercial real estate;

• approximately 350,000 CoStar and approximately 330,000 Comps commercial real estate properties;

• information for 54 U.S. markets;

• over two billion square feet of space available;

• over 38,000 properties for sale;

• approximately 900,000 tenants occupying commercial real estate space;

• more than 530,000 sales transactions valued at over $660 billion; and

• over 660,000 high-resolution digital images, including building photographs, aerial photographs, plat maps

and floor plans.

This highly complex database is comprised of hundreds of data fields, tracking such categories as:

• Location

• Site and zoning information

• Building characteristics

• Space availability

• Tax assessments

• Ownership

• Sales comparables

CoStar Research

• Mortgage and deed information

• For-sale information

• Income and expense histories

• Tenant names

• Lease expirations

• Contact information

• Historical trends

We  have  developed  a  sophisticated  data  collection  organization, made  up  of  a  combination  of  researchers,

license agreement, management systems, computer and communications hardware, and software systems.

2

Research Department. As of March 13, 2000, over 700 commercial real estate research professionals worked
for us. CoStar’s researchers collect and analyze office and industrial real estate information through hundreds of
thousands of phone calls, e-mails, internet updates and faxes a year, in addition to field inspections, news monitor-
ing, and direct mail. Every new research employee undergoes an extensive training program to maintain a consistent
research process. Because of the importance commercial real estate professionals place on our data and our prominent
position in the industry, these professionals frequently take the initiative to report transactions to our researchers.

In connection with obtaining sales comparable data, Comps researchers review multiple sources of informa-
tion  to  comprehensively  identify  recent  commercial  property  transactions  in  47  markets  throughout  the  United
States. Once a potential transaction is identified, Comps researchers inspect county courthouse records and extract
pertinent information directly from the recorded deed into the database in order to increase the accuracy of each
sales comp report. Comps researchers match the legal description of the deed with a tax or plat map and then pro-
ceed to perform a site inspection on the commercial properties. The site inspection consists of photographing the
building, measuring the building (if necessary), counting parking spaces, assessing property condition and con-
struction, and gathering tenant information. Comps researchers then interview buyers, sellers and brokers via tele-
phone to seek to confirm the information and to gather additional information.

As  of  March  13, 2000, over  200  field  researchers  compiled  digital  images, location  information  and  site-
specific data for us, by both verifying data in CoStar’s database and entering new data into the database. Some of
these researchers use CoStar trucks equipped with Global Positioning Systems, which use satellites to keep track
of the trucks’ location and pinpoint building locations. As of March 13, 2000, CoStar had 29 trucks in a total of 19
markets that were used by field researchers. In addition, over 100 of our field researchers are photographers who
take  photographs  of  commercial  real  estate  properties  for  CoStar  to  add  to  the  collection  of  CoStar’s  digital
images in our database.

License Agreements. We  license  a  small  portion  of  our  data  from  public  record  providers  such  as Axciom
DataQuick, TransAmerica/Intellitech and First American RES. The licensing agreements with these entities pro-
vide for the use of certain of their national property ownership information in the enhancement and development
of various CoStar services.

Management and Quality Control Systems. We use both automated and non-automated controls to ensure the
integrity of the data collection process. A large number of automated data quality tests check for potential errors
including occupancy date conflicts, available square footage greater than building area, typical floor greater than
land area, and expired leases. Our non-automated quality control procedures include:

• calling our information sources on recently-updated properties to re-verify information;

• reviewing commercial real estate periodicals for transactions to cross-check our research; and

• performing field checks to determine if we correctly canvassed all buildings.

Finally, one of the most important and effective quality control measures is feedback, garnered through regu-

lar client surveys taken from the commercial real estate professionals using our data every day.

Computer and Communications Hardware. We maintain 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. We store full
data back-ups off site.

Software Systems. We use client-server software to manage our internal data collection. In addition, over the
past decade we have developed and refined our own software systems. This software has four primary functions:

• collection of building-specific data;

• tracking of commercial real estate companies and individuals;

• facilitation of our operations; and

• distribution of data.

Products and Services

Our various current and planned products and services are described in detail in the following paragraphs.

CoStar Exchange. We have developed a database of over 38,000 commercial properties for sale with a com-
bined  asset  value  in  excess  of  $40  billion. We  expect  to  distribute  that  information  in  a  broker-centric  model
through  a  secure Web-based  browser, to  be  known  as  CoStar  Exchange. We  expect  that  sellers  and  brokers  of
properties will be able to list extensive information about their properties for sale on the site at no cost. The site
will afford an efficient means for these sellers to reach a large universe of potential buyers. We expect that poten-
tial buyers will pay a subscription fee to access the system. Sellers of investment-grade properties will have the
additional  option  of  selecting  limited, secure  distribution  of  their  properties  in  order  to  address  confidentiality
requirements. We expect that the CoStar Exchange service will integrate the content developed through years of
research  under  the  CoStar  Property, CoStar  Tenant, CoStar  COMPS  and  other  CoStar  services. We  expect  to
release CoStar Exchange in the second quarter of 2000.

CoStar  Property. CoStar  Property  has  fostered  the  development  of  the  digital  leasing  marketplace.
Subscribers use CoStar Property to research leasing options, analyze market conditions and competitive property
positions, and produce multimedia client presentations. Members of the broader commercial real estate commu-
nity, including non-CoStar subscribers, utilize CoStar Property extensively to market their properties. Subscribers
can query CoStar Property with any combination of pertinent criteria, combining any of approximately one hun-
dred data fields from categories such as building size, location, building characteristics, space availability, owner-
ship, or sales comparables. CoStar Property’s search engine scans through hundreds of millions of square feet of
space in a specified market in seconds to find all the properties meeting the search criteria. Our subscribers can
select from over 50 customizable reports, presenting space availability, comparable sales, tenant activity, market
statistics, photographs, and floor plans. Users can export and edit reports, photos, and floor plans to help deter-
mine feasibility of a specific space. Our subscribers also use CoStar Property to analyze market conditions by cal-
culating current vacancy rates, absorption rates, or average rental rates.

CoStar  Tenant. CoStar  Tenant  delivers  detailed  information  profiling  the  tenants  occupying  commercial
buildings  by  tracking  tenants  in  28  U.S.  markets.  A  key  service  feature  is  lease  expiration  information.
Subscribers use CoStar Tenant to gather information about particular tenants, identify and target the most likely
tenants to lease space, ascertain all tenants in a particular building, understand trends and the underlying demand
for  commercial  real  estate, locate  and  target  the  tenants  most  likely  to  need  representation  for  their  real  estate
requirements, and pinpoint the tenants most likely to buy a particular vendor’s goods and services.

CoStar  COMPS. Through  the  acquisition  of  Comps  in  February  2000, we  now  provide  comprehensive,
national information on comparable sales information in the commercial real estate industry. This service is pro-
vided for 47 markets nationally representing 145 counties, through a Web-based system and includes information
on sale prices, income and expenses, capitalization rates, loan data and other key details. Customers may search
the proprietary database of comparable sale information by multiple search parameters, including location, prop-
erty type, square footage, price range and number of units. Customers receive a report of all relevant properties in
the database matching their search criteria, including photographs.

CoStar ARES. Through the acquisition of ARES Development Group, LLC in September 1999, we are now
the provider of CoStar ARES 2000, a leading contact management and business tool for commercial real estate
professionals. CoStar ARES 2000 works in conjunction with ACT! 2000 and turns ACT! into a real estate pro-
ductivity system by providing commercial real estate elements that are not provided by ACT!. Users of CoStar
ARES 2000 can import data from CoStar Property and CoStar Tenant into CoStar ARES 2000.

CoStar  Marketplace. CoStar  Marketplace  provides  an  on-line  means  for  the  commercial  real  estate  and
related  business  community  to  direct  advertising  to  the  appropriate  decision-makers. We  currently  deliver  this
service  through  our  CoStar  services  and  via  our Website.  This  service  benefits  our  clients  by  providing  them
increased distribution, higher visibility, and a more cost-effective way to reach their targeted audience for their
advertising materials.

CoStar News. Our Website, our CoStar services, and our e-mail news dispatches have become an accepted
source of reliable industry news. In 1999, we authored over 5,000 news stories. These articles have been cited by
numerous major news organizations. Our newswire feature keeps clients informed of late-breaking commercial
real estate news such as deals signed, acquisitions, ground breakings and other features.

CoStar  Analytic. We  currently  provide  a  full  line  of  detailed  analytical  tools  and  reports  through  CoStar
Property and CoStar Tenant. These tools provide strategic insight into the changing trends in vacancy rates, tenant
movements, supply, new  construction, absorption  rates, and  other  important  market  metrics. We  are  enhancing
these services through CoStar Analytic. Once released, we expect that CoStar Analytic will provide a Web-based
analytic  tool  that  will  allow  users  to  perform  more  sophisticated  analyses  of  underlying  market  conditions  and
trends  when  making  investment, leasing, purchase, sale, construction, and  marketing  decisions  involving  com-
mercial real estate. We may also provide fee-based customized reports and advisory services.

Backlog. We do not have a significant backlog and do not believe that backlog is a meaningful indicator of

our future results.

Clients

We  draw  clients  from  across  the  commercial  real  estate  and  related  business  community.  Commercial  real
estate brokers have traditionally been the largest portion of CoStar clients. Recently, however, the fastest growing
segments for CoStar services have been owners, lenders, and vendors. The following chart provides representative
clients in various categories.

As of March 13, 2000, CoStar had an estimated 25,000 end users at over 3,600 clients using one or more of
CoStar’s  products, and  Comps  had  an  estimated  25,000  end  users  at  over  6,000  clients  using  one  or  more 
of  Comps’ products.  This  includes  the  majority  of  the  national  commercial  real  estate  brokerage  firms. As  of
December 31, 1999, no single client accounted for more than 5% of our revenues. During the past five years, our
contract renewal rate has exceeded 90%.

Sales and Marketing

As of March 13, 2000, we had over 130 sales and marketing employees, with the majority of our direct sales
force located in the field. Our sales teams are geographically focused and located in 23 field sales offices in our
largest U.S. markets. Our offices typically serve as the platform for our in-market sales, client service, and field
research operations for their respective regions. The field sales offices also work with our headquarters operation to
coordinate sales to our multi-market and national clients. In addition, we have a client service staff with responsi-
bility for installing and training our client base, ensuring high client satisfaction, renewing existing client contracts,
and identifying cross-selling opportunities. We use a proprietary enterprise-wide client management system inte-
grated with our database and telecommunications system. This integrated system allows the sales force, research
staff, client service, and accounting department to develop a coordinated sales and account management effort.

Our  field  sales  people  focus  in  one  of  three  areas, Information  Solutions, Marketing  Solutions  or  CoStar
ARES  2000. The  Information  Solutions  sales  personnel  focus  on  existing  information  services  such  as  CoStar
Property, CoStar Tenant and CoStar COMPS, and will in the future focus on new information services, such as
CoStar Exchange and CoStar Analytic. Many of our salespeople have significant commercial real estate experience,
allowing them to take a consultative sales approach. The Marketing Solutions sales personnel sell on-line adver-
tising on our website, www.costargroup.com, and advertising spaces in the CoStar Property and CoStar Tenant
regional newswires. Many of these sales people have an advertising sales background or experience in commer-
cial real estate. A team of inside and field sales people, together with a team of telemarketing sales people, work
to  sell  CoStar ARES  2000.  Our  sales  strategy  is  to  aggressively  attract  new  clients, while  providing  ongoing
incentives for existing clients to subscribe to our newer services.

We seek to make our services essential to our clients’ businesses. To encourage clients to use our services reg-
ularly, we  generally  charge  fixed  monthly  amounts  rather  than  fees  based  on  actual  system  usage.  Our  clients’
monthly charges are based on the number of sites, organization size, the company’s business focus, and the num-
ber of services to which a client subscribes.

Our primary marketing methods include: service demonstrations, direct marketing, trade show and industry
events, print  advertising, and  client  referrals.  Direct  marketing  is  the  most  cost  effective  means  for  us  to  find
prospective clients. Once we have identified a prospective client, we have found the most effective sales method is
a  service  demonstration.  Our  direct  marketing  efforts  include  direct  mail, e-mail, and  telemarketing, and  make
extensive use of our unique, proprietary database. Our advertising includes Internet banners, private network ban-
ners, and traditional print advertising. This form of advertising is used for brand identity, message reinforcement,
and potential client identification. We also attend industry tradeshows and seminars to reinforce our relationships
with our core user groups.

Competition

The market for information systems and services generally is competitive and rapidly changing. The market
for Internet services and providers is relatively new, intensely competitive and rapidly changing. In the commer-
cial real estate industry, the principal competitive factors for commercial real estate information are:

• quality and depth of the underlying databases;

• ease of use, flexibility, and functionality of the software;

• timeliness of the data;

• breadth of geographic coverage and services offered;

• perception that the service offered is the industry standard;

• proprietary nature of methodologies, databases and technical resources;

• effectiveness of marketing and sales efforts;

• client service and support;

• vendor reputation;

• brand loyalty among customers;

• capital resources; and

• price.

6

We compete directly and indirectly for customers with the following categories of companies:

• online services or Web sites targeted to commercial real estate brokers, buyers and sellers of commercial
real  estate  properties, insurance  companies, mortgage  brokers  and  lenders, such  as  Propertyfirst.com,
LoopNet, Inc. and Realtyiq.com;

• publishers and distributors of information services, such as regional providers such as Realty Information

Tracking Services, and smaller local providers, and national print publications such as Black’s Guide;

• in-house research departments operated by some commercial real estate brokers; and

• public record providers such as First American Res, Axciom DataQuick and TransAmerica, though many of
their customers view these public record providers as complementary to our services and often subscribe to
one of these services as well as Comps’ service.

As  the  digital  real  estate  marketplace  develops, additional  competitors  (including  companies  which  could
have greater financial, product development, technical, and marketing resources than we do) may enter the market
and competition may intensify. While we believe that we have successfully differentiated ourselves from existing
or potential competitors, competition could materially harm our business.

Proprietary Rights

To protect our proprietary rights in our methodologies, database, software, trademarks and other intellectual

property, we depend upon a combination of:

• trade secret, copyright and trademark laws;

• nondisclosure, noncompetition and other contractual provisions with employees;

• license agreements with customers;

• patent protection; and

• technical measures.

We  seek  to  protect  our  software’s  source  code  and  our  database  as  trade  secrets  and  under  copyright  law.
Although copyright registration is not a prerequisite for copyright protection, we have filed for copyright registra-
tion  for  our  databases, software  and  other  materials.  Under  current  law, the  arrangement  and  selection  of  data 
may be protected, but the actual data itself may not be. Moreover, other people are free to try to independently
create databases that perform the same function as ours. We believe, however, that they would find it very time-
consuming  and  costly  to  create  a  competing  database. We  license  our  database, software  and  services  under
license agreements that grant our clients non-exclusive, non-transferable licenses. These agreements restrict the
disclosure and use of our data, images and software. In addition, the license agreements prohibit the unauthorized
reproduction or transfer of the information and software we license.

We also attempt to protect the secrecy of our proprietary database, our trade secrets and our proprietary infor-
mation through confidentiality and noncompetition agreements with our employees and consultants. Our services
also include technical measures to discourage unauthorized copying.

We have filed trademark applications to register the “CoStar” mark in the United States and Canada, and we
have a registered trademark for “CoStar” in the United Kingdom. In addition, we have filed trademark applica-
tions  to  register  trademarks  for  a  variety  of  names  for  the  CoStar  products  and  other  marks.  In  addition,
“COMPS” is  a  registered  trademark  of  Comps. We  recently  filed  a  patent  application  covering  certain  of  our
methodologies and software.

On September 30, 1999, CoStar filed suit against LoopNet, Inc and its president Dennis DeAndre in the U.S.
District  Court  for  the  District  of  Maryland. The  complaint  asserts, among  other  things, that  LoopNet  infringed
CoStar’s  copyrights  by  unlawfully  displaying  and  distributing  CoStar’s  copyrighted  photographs  on  LoopNet’s
web site. On March 14, 2000, the judge issued a preliminary injunction ordering LoopNet, Inc. to remove CoStar
photographs from the LoopNet website once CoStar notifies it of any possible infringement. The injunction also
requires that LoopNet notify users whenever it removes CoStar photographs submitted for posting on LoopNet’s
Web site. It also mandates that LoopNet require certain repeat offenders to produce evidence of copyright owner-
ship before posting any photograph to the LoopNet Web site. In its suit, CoStar is seeking monetary damages for
past infringements, attorney’s fees and a permanent injunction against LoopNet.

Employees

As of March 13, 2000, we employed 960 employees. None of our employees is represented by a labor union.

We have experienced no work stoppages. We believe that our employee relations are excellent.

Item 2 Properties

Our  corporate  headquarters  occupy  approximately  48,000  square  feet  in  Bethesda, Maryland, under  leases
and subleases expiring between April 30, 2000 and July 31, 2000. In April 2000, we expect to move to a new cor-
porate  headquarters  in  Bethesda, Maryland, occupying  approximately  60,000  square  feet  under  a  lease  that
expires on March 14, 2010. Comps is headquartered in San Diego and leases approximately 40,000 square feet
under  a  lease  that  expires  on August  31, 2002  and  leases  approximately  43,000  square  feet  under  a  lease  that
expires on January 31, 2004. We believe that our Bethesda, Maryland and San Diego facilities will be adequate to
meet our requirements for our headquarters for the foreseeable future.

We also lease office space in a variety of other locations, including, without limitation, the following: New
York;  Los Angeles;  Chicago;  San  Francisco;  Boston;  Newport  Beach;  Philadelphia;  Houston;  Mason, Ohio;
Atlanta; Phoenix; Southfield, Michigan;  Iselin, New Jersey; Charlotte, North Carolina; Ft. Lauderdale, Florida;
Seattle; Denver; Austin; Dallas; Sacramento, California; and Tampa, Florida.

Item 3 Legal Proceedings

On November 5, 1999, a suit was filed in the Court of Chancery of the State of Delaware in and for New
Castle County under the caption Morris v. Avis, et al (C.A. 197554). The suit alleged breaches of fiduciary duties
by the former members of the board of directors of Comps and Summit Partners. On November 8, 1999, a suit
was filed in the Superior Court of the State of California of and for the County of San Diego captioned Berghoff
v. Comps.com et al (case no. GIC 738362). The allegations in the California lawsuit are similar to the allegations
in the Delaware suit. The plaintiffs in both of these lawsuits had requested monetary damages and injunctive relief
to prevent the consummation of the merger between Comps and CoStar. On January 6, 2000, the Delaware suit
was voluntarily dismissed by the plaintiff. On February 4, 2000, the parties to the California lawsuit entered into
a  Memorandum  of  Understanding  that  sets  forth  their  agreement  to  settle  the  lawsuit.  The  parties  are  in  the
process of fully documenting the settlement of the class action in order to obtain the necessary court approval. A
hearing has been scheduled in the California action on March 29, 2000 to address the status of this matter. The
parties intend to seek the preliminary approval by the court of the settlement either at this hearing or at a subse-
quent hearing to be scheduled shortly thereafter.

The Company currently and from time to time is involved in other litigation incidental to the conduct of its
business. The  Company  is  not  a  party  to  any  lawsuit  or  proceeding  that, in  the  opinion  of  management  of  the
Company, is likely to have a material adverse effect on the Company’s financial position or results of operations.

Item 4 Submission of Matters to a Vote of Security Holders

The  registrant  did  not  submit  any  matters  to  a  vote  of  its  security  holders  during  the  quarter  ended

December 31, 1999.

Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

CoStar is the leading provider of information services to the U.S. commercial real estate industry. We are cre-
ating a digital marketplace where the members of the commercial real estate and related business community can
continuously interact and facilitate transactions by efficiently exchanging accurate and standardized information.
Our wide array of digital service offerings includes a leasing marketplace, a selling marketplace, comparable sales
information, decision support, tenant information, property marketing, and industry news. Substantially all of our
current services are digitally delivered over the Internet.

We completed our initial public offering in July 1998 and received net proceeds of approximately $22.7 mil-
lion. We primarily used those net proceeds to fund the geographic and service expansion of our business, includ-
ing three strategic acquisitions, and to expand our sales and marketing organization. In May 1999, we completed
a follow-on public offering and received net proceeds of approximately $97.4 million. We used a portion of those
net proceeds to fund the acquisition of Comps, and we expect to use the remainder of the proceeds primarily for
development and distribution of new services, expansion of all existing services across our current markets, geo-
graphic  expansion  in  the  U.S.  and  international  markets, strategic  acquisitions  and  working  capital  and  general
corporate purposes.

From 1994 through 1999, we expanded the geographical coverage of our existing services and developed new
services.  In  addition  to  internal  growth, this  expansion  included  the  acquisitions  of  Chicago  ReSource, Inc.  in
Chicago in 1996 and New Market Systems, Inc. in San Francisco in 1997. In August 1998, we expanded into the
Houston region through the acquisition of Houston-based real estate information provider C Data Services, Inc. In
January 1999, we expanded further into the Midwest and Florida by acquiring LeaseTrend, and into Atlanta and
Dallas/Fort Worth by acquiring Jamison. In September 1999, we acquired ARES, a Los Angeles based developer
and distributor of ARES for ACT!. In February 2000, we acquired Comps discussed in detail later in this section.

We consider regions that have had ongoing operations for at least 18 months to be established, and we cur-
rently generate positive cash flow from our operations in established regions. As of December 31, 1999, the fol-
lowing  regions  are  those  that  have  been  in  operation  for  more  than  18  months  and  that  we  consider  to  be
established: Washington, New York, Los Angeles, Chicago, San  Francisco, Philadelphia  and  Boston.  These
regions provide us with substantial cash flow, which we reinvest into the business. Since our inception, the devel-
opment of our business has required substantial investments for the expansion of services and the establishment of
operating regions, which has resulted in substantial net losses on an overall basis.

The incremental cost of introducing new services in an established region in the future may reduce the prof-
itability of a region or cause it to incur losses. We expect continued development and distribution of new services,
expansion of all existing services across current markets and geographic expansion in the U.S. and international
markets. Therefore, while we expect operations in existing established regions to remain profitable and provide
substantial funding, we expect our overall expansion plans to generate significant losses and negative cash flow
from operations during the next two years.

Although our services are expanding rapidly, our CoStar Property and CoStar Tenant services currently gen-
erate the largest portion of our revenue. The CoStar Property and CoStar Tenant contracts range from terms of one
to three years and generally renew automatically. Upon renewal, many of the contract rates increase automatically
in accordance with contract provisions or as a result of renegotiations. To encourage clients to use our services
regularly, we charge fixed amounts rather than fees based on actual system usage. We charge our clients based on
the number of sites, organization size, the company’s business focus, and the number of services to which a client
subscribes. Our contract renewal rate currently exceeds 90% on an annual basis. Our clients pay contract fees on
an annual, quarterly, or monthly basis. We recognize this revenue over the life of the contract on a straight-line basis
beginning with the installation or renewal date. Annual and quarterly advance payments result in deferred revenue,
substantially reducing the working capital requirements generated by the growth in our accounts receivable.

As explained in the Notes to the Consolidated Financial Statements that appear later in this report, the finan-
cial  data  for  1997  through  1999  is  derived  from  the  audited  financial  statements  of  us  and  of  our  predecessor
companies for those years.

Comparison of Year Ended December 31, 1999 and Year Ended December 31, 1998

Revenues. Revenues grew 118% from $13.9 million in 1998 to $30.2 million in 1999. This increase resulted
principally from growth in our client base in all regions we served, expansion into new regions, and expansion of
our services in existing regions. Revenues from regions we considered established as of December 31, 1999 grew
from $13.1 million in 1998 to $19.8 million in 1999, an increase of 51%. During 1999, we expanded into Seattle
and acquired and converted over twenty regions, including Atlanta, Dallas, Denver, Florida and the Midwest. Our
advertising revenues, which we generated primarily in our established regions, increased 66% from $969,000 in
1998 to $1.6 million in 1999.

Gross Margin. Gross margin increased from $9.3 million in 1998 to $17.0 million in 1999. While gross mar-
gin increased in total, as a percentage of revenues it decreased from 67% to 56%. The increase in gross margin
amounts resulted principally from significant revenue growth from established regions. The decline in gross mar-
gin percentages resulted from expansion of services in established regions, an increase in the number of emerging
regions  and  lower  gross  margins  in  the  newly  acquired  regions.  Furthermore, our  cost  of  revenues  for  the  year
ended December 31, 1999 includes purchase price amortization from the LeaseTrend, Jamison and ARES acqui-
sitions of approximately $682,000.

Selling and Marketing Expenses. Selling and marketing expenses increased 174% from $7.2 million in 1998
to $19.9 million in 1999 and increased as a percentage of revenues from 52% in 1998 to 66% in 1999. Selling and
marketing expenses increased as a result of the cost of the acquired sales organizations and purchase price amor-
tization of an aggregate amount of approximately $1.6 million for the Jamison, LeaseTrend and ARES acquisi-
tions  for  the  year  ended  December  31, 1999.  In  addition, continued  expansion  of  the  sales  organization  and
marketing efforts required for growth, particularly in emerging and acquired regions, including Phoenix, Houston,
Denver, Florida and the Midwest, contributed to the increased expenses.

Software Development Expenses. Software development expenses increased 57% from $704,000 in 1998 to
$1.1 million in 1999, but decreased as a percentage of revenues from 5% in 1998 to 4% in 1999. The increase in
expenses reflects development costs for the expansion of services for emerging and established regions and new
service initiatives.

General and Administrative Expenses. General and administrative expenses increased 132% from $4.9 mil-
lion  in  1998  to  $11.4  million  in  1999  and  increased  as  a  percentage  of  revenues  from  35%  in  1998  to  37%  in
1999. General and administrative expenses increased due to the hiring of new employees to support the expanding
scope  of  our  operations  and  client  base, as  well  as  the  increased  administrative  costs  of  a  public  company.
Additionally, our general and administrative expenses include an aggregate amount of approximately $1.3 million
of purchase price amortization from the LeaseTrend, Jamison and ARES acquisitions.

12

Other Income. Other income increased from $341,000 in 1998 to $3.1 million in 1999. This increase resulted
from an increase in interest income due to our higher average cash balances in 1999, reflecting the net proceeds
from our follow-on public offering in May 1999.

Comparison of Year Ended December 31, 1998 and Year Ended December 31, 1997

Revenues. Revenues grew 76% from $7.9 million in 1997 to $13.9 million in 1998. This increase resulted
principally from growth in our client base in all regions we served, expansion into new regions, and expansion of
our services in existing regions. Revenues from regions we considered established as of December 31, 1998 grew
from  $7.9  million  in  1997  to  $13.1  million  in  1998, an  increase  of  66%.  During  1998, we  also  expanded  into
Houston, Sacramento, Phoenix, and San Diego. Our advertising revenues, which we generated primarily in our
established regions, increased 139% from $405,000 in 1997 to $969,000 in 1998.

Gross Margin. Gross margin increased from $4.5 million in 1997 to $9.3 million in 1998. This increase rep-
resented an improvement from 57% to 67% of revenues. The increase resulted principally in established regions,
where revenue growth exceeded the growth of cost of revenues, which remained relatively constant.

Selling and Marketing Expenses. Selling and marketing expenses increased 66% from $4.4 million in 1997
to $7.2 million in 1998, but decreased as a percentage of revenues from 55% in 1997 to 52% in 1998. Selling and
marketing expenses increased as we expanded our sales organization into new regions and began to enhance our
selling and marketing capabilities on a national basis. Selling expenses declined as a percent of revenues due to
sales growth during the year and the growing renewable contract base.

General and Administrative Expenses. General and administrative expenses increased 63% from $3.0 mil-
lion in 1997 to $4.9 million in 1998, but decreased as a percentage of revenues from 38% in 1997 to 35% in 1998.
General and administrative expenses increased because we hired new employees to support our expanding organ-
ization and client base, and also in response to increases in our occupancy and communication costs. General and
administrative expenses decreased as a percentage of revenues due to the continued leveraging of corporate over-
head costs over a larger organization with an expanding client base.

Other  Income. Other  income  increased  from  $33,000  in  1997  to  $341,000  in  1998. This  increase  resulted
from an increase in interest income due to our higher average cash balances in 1998, reflecting the net proceeds
from our initial public offering in July 1998.

LeaseTrend, Inc. Acquisition

On January 8, 1999, the Company acquired all of the common stock of LeaseTrend, Inc., a Cincinnati based
provider of commercial real estate information, for approximately $4.5 million in cash and 566,671 shares of the
Company’s common stock. The transaction was accounted for as a purchase and the consideration was valued for
accounting purposes at approximately $9.2 million including acquisition expenses.

Jamison Research, Inc. Acquisition

On January 22, 1999, the Company acquired all of the common stock of Jamison Research, Inc., an Atlanta
based provider of commercial real estate information, for approximately $5.3 million in cash and 446,637 shares
of the Company’s common stock. The transaction was accounted for as a purchase and the consideration was val-
ued for accounting purposes at approximately $10.3 million including acquisition expenses.

Ares Development Group, LLC Acquisition

On  September  15, 1999, the  Company  acquired  all  of  the  membership  interests  of ARES  Development
Group, LLC, Los Angeles based developers and distributors of ARES for ACT!, for $250,000 in cash and 33,208
shares of the Company’s common stock. The transaction was accounted for as a purchase and the consideration
was valued for accounting purposes at approximately $1,265,000 including acquisition expenses. In addition, the
acquisition agreement provides for $1,000,000 of additional consideration (in a combination of cash and stock)
that may be paid by the Company upon the achievement of certain operating goals by the members of ARES. In
February 2000, we issued 2,140 shares of our common stock and paid $437,500 in cash to the members of ARES
for the achievement of the first of the operating goals by the members of ARES.

COMPS.COM, Inc. Acquisition

On February 10, 2000, CoStar completed the acquisition of Comps under a merger agreement, dated as of
November 3, 1999, among CoStar, Comps and Acq Sub, Inc. (“Acq Sub”), a wholly-owned subsidiary of CoStar.
Comps’ primary asset is a database of commercial real estate sales information. In connection with the transac-
tion, Comps was merged with and into Acq Sub, which was the surviving corporation in the merger. Immediately
after  the  merger, Acq  Sub  changed  its  name  to  Comps, Inc. The  merger  agreement  provided  for  each  share  of
Comps  common  stock  to  receive  either  $7.50  in  cash  or  0.31496  shares  of  CoStar  common  stock, subject  to
adjustment to ensure that 50.1% of the Comps shares received CoStar common stock and 49.9% of the Comps
shares received cash. The aggregate consideration included:

• $49,015,905 in cash paid to former holders of Comps common stock (excluding cash paid for fractional

shares); and

• 2,258,738 shares of CoStar common stock (including shares issued to former warrant holders of Comps).

Comps reported a cash and short term investment balance of approximately $49.5 million at September 30,
1999, which resulted from its initial public offering in May 1999. Comps also reported long term debt of approx-
imately  $3.8  million  at  September  30, 1999. Although  Comps  was  experiencing  operating  losses  and  negative
cash flow from operations, the remaining cash and short term investments at the closing date significantly offset
the overall cash consideration for the purchase of Comps by the Company. The cash portion of the purchase price

14

was obtained by CoStar from the proceeds from the sale of its common stock in a public offering in May 1999.
We will make significant investments to integrate Comps into our organization, including costs to:

• upgrade computer systems;

• establish network connections;

• convert database structures;

• train personnel; and

• migrate Comps clients to our services.

We are taking steps to reduce the operating losses and negative cash flow of our Comps subsidiary, but we
expect these losses and negative cash flow to continue throughout the year 2000. Additionally, CoStar will expe-
rience  significant  charges  to  operations  for  the  amortization  of  intangible  assets  resulting  from  the  acquisition.
These assets will be amortized over lives of two to ten years.

Liquidity and Capital Resources

Our cash and cash equivalents balance was $94,074,127 at December 31, 1999, an increase of $74,407,240
from $19,666,887 at December 31, 1998. This increase was due principally to the $97.4 million in proceeds from
the follow-on public offering, which was offset by cash used for the acquisitions of LeaseTrend and Jamison in
January 1999 and ARES in September 1999, cash used in operating activities, $4,520,375 in purchases of property
and equipment and $1,589,060 in purchased building photography. During the year ended December 31, 1999, we
financed our operations and growth through cash flow from the established regions and the proceeds of the public
offerings. Net cash used in operations for the year ended December 31, 1999 was $7,476,662 compared to net
cash used in operating activities of $293,426 for the year ended December 31, 1998. This was a direct result of
expenditures required for the expansion in the emerging and acquired regions. We continue to experience overall
operating losses as a result of our recent expansion into emerging and acquired regions, while established regions
continue to generate substantial cash flow from operations.

Net cash used in investing activities amounted to $16,456,157 for the year ended December 31, 1999, includ-
ing $9,736,950 (net of acquired cash) for the acquisition of LeaseTrend, Jamison and ARES. Additional investing
activities included capitalized product development costs, purchased building photography, and purchase of prop-
erty and equipment, consisting principally of computer and office equipment. As a result of our expansion, we
have  entered  into  numerous  operating  leases  for  office  space  throughout  the  country, including  CoStar’s  and
Comps’ headquarters, and have commitments for rent payments ranging from $2,435,563 to $4,133,782 annually
over the next ten years. Other than such leases and related commitments for leasehold improvements, we currently
have no material commitments for capital expenditures.

To date, we have grown in part by acquiring other companies, and we may continue to make acquisitions. Our
acquisitions may vary in size and could be material to our current operations. We expect to use cash, stock, or
other means of funding to make these acquisitions.

We expect to incur significantly higher costs, particularly as we introduce new and upgraded services, expand
geographically, and  develop  the  infrastructure  to  support  the  expanding  organization  and  client  base.  Based  on
current plans, we believe that our available cash combined with positive cash flow from our established regions
should be sufficient to fund our operations for at least the next two years.

Through September 30, 1998, we operated as either a Subchapter S corporation or a limited partnership, and
we were not subject to corporate income taxes. After September 30, 1998, we became a taxable entity. Although
we have experienced losses to date, future profits, to the extent not offset by the benefits of loss carryforwards,
would result in income tax liabilities. We do not expect to benefit substantially from tax loss carryforwards gener-
ated  prior  to  July  1998.  Further, the  reversal  of  deferred  taxes  of  approximately  $7.0  million  at  December  31,
1999, recorded in connection with the purchase of acquired intangibles, will result in a non-cash income tax ben-
efit in future periods.

We do not believe the impact of inflation has significantly affected our operations.

15

Year 2000

We are not aware of any Year 2000 issues that have affected our business. The amounts that we expended in
connection with Year 2000 compliance were not significant, as we undertook most of our activities in the normal
course of business. We estimate, however, that we spent approximately $1 million in 1999 in connection with Year
2000 compliance.

It is possible that the Company’s computerized systems could be affected in the future by the Year 2000 issue.
The Company has numerous computerized interfaces with third parties that are possibly vulnerable to failure if
those  third  parties  have  not  adequately  addressed  their Year  2000  issues.  System  failures  resulting  from  these
issues could cause disruption to the Company’s operations.

Cautionary Statement Concerning Forward-Looking Statements

We have made forward-looking statements in this Report that are subject to risks and uncertainties. Forward-
looking statements include information that is not purely historic fact, including statements concerning the finan-
cial outlook for 2000 and estimates for the future, our possible or assumed future results of operations generally,
new  products  and  services  that  we  expect  to  release, and  other  statements  and  information  more  specifically
regarding assumptions about our earnings per share, capital and other expenditures, financing plans, cash flow,
capital  structure, pending  legal  proceedings  and  claims, future  economic  performance, operating  income, man-
agement’s plans, goals and objectives for future operations and growth and markets for stock. The sections of this
Report, which  contain  forward-looking  statements, include  “Business”, “Properties”, “Legal  Proceedings” and
“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Our  forward-looking  statements  are  also  identified  by  words  such  as  “believes,” “expects,” “anticipates,”
“intends,” “estimates” or  similar  expressions. You  should  understand  that  these  forward-looking  statements  are
necessarily estimates reflecting our judgment, not guarantees of future performance. They are subject to a number
of assumptions, risks and uncertainties that could cause actual results to differ materially from those expressed or
implied in the forward-looking statements. You should understand that the following important factors, in addition
to those discussed in “Risk Factors”, could affect the our future results and could cause those results or other out-
comes to differ materially from those expressed or implied in our forward-looking statements: competition and
technological innovation by competitors; sensitivity to general economic conditions and events that affect com-
mercial  real  estate  in  particular;  business  combinations  and  strategic  alliances  by  other  industry  participants;
growth  in  commerce  conducted  over  the  Internet;  changes  in  relationships  with  real  estate  brokers  and  other
strategic partners; and legal and regulatory issues.

Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the
date of this Report. All subsequent written and oral forward-looking statements attributable to us or any person
acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to
in  this  section. We  do  not  undertake  any  obligation  to  release  publicly  any  revisions  to  these  forward-looking
statements to reflect events or circumstances after the date of this Report or to reflect the occurrence of unantici-
pated events.

Risk Factors

Our future profitability is uncertain due to our continuing operating losses. We have never recorded an over-
all operating profit because the investment required for geographic expansion and new services has exceeded the
profits generated in our established markets. We intend to continue to invest in expansion and new services and
will  therefore  sustain  substantial  losses  for  at  least  the  next  two  years.  Our  ability  to  earn  a  profit  will  largely
depend on our ability to generate profits from services that exceed our investment in geographic expansion and
new services. We may not be able to generate revenues sufficient to earn a profit, to maintain profits on a quarterly
or annual basis, or to sustain or increase our future revenue growth.

Our operating results may fluctuate significantly. Our revenues and operating results may fluctuate with gen-
eral economic conditions and also for many other reasons, such as: our investments in geographic expansion; the
timing of new service introductions and enhancements; the success of new products; the timing of investing the
net proceeds from our offerings; acquisitions of other companies or assets; sales and marketing promotional activ-
ities; loss of clients or revenues due to consolidation in the real estate industry; changes in client budgets; or our
investments in other corporate resources.

16

We may not achieve the cost savings and sales enhancements that we expect to result from the integration of
CoStar and Comps. The merger between CoStar and Comps may not be successful unless we realize significant
cost savings and increased sales. Our success in realizing these cost savings and increased sales, and the timing of
this realization, depend on the quality and speed of the integration of CoStar and Comps. We have established an
integration team that has identified specific areas for cost savings and is continuing to plan the coordination of the
two companies. However, we may not realize the cost savings and sales enhancements that we anticipate from
integrating operations following completion of the merger as fully or as quickly as we expect for a number of rea-
sons, including: errors  in  planning  or  integration;  delays  in  implementing  the  integration  plan;  and  unexpected
events such as major changes in the markets in which we operate.

We  may  not  be  able  to  successfully  introduce  new  products,  including  our  CoStar  Exchange  product. Our
future business and financial success will  depend on our ability to continue to introduce new  products into the
marketplace. Developing new products, such as CoStar Exchange, imposes heavy burdens on our systems devel-
opment department, product managers, management and researchers. In addition, successfully launching and sell-
ing a new product, such as CoStar Exchange, puts pressure on our sales and marketing resources. If we are unable
to develop new products, such as CoStar Exchange, then our customers may choose a competitive service over
ours and our business may be adversely affected. In addition, if we incur significant costs in developing new prod-
ucts, such as CoStar Exchange, or are not successful in marketing and selling these new products, it could have a
material adverse effect on our results of operations.

We may not be able to complete successfully our planned expansion. Our future business and financial suc-
cess  will  depend  on  our  ability  to  continue  to  expand  our  services  and  the  areas  where  we  do  business. These
expansion efforts must occur while information technology is rapidly changing. These efforts impose additional
burdens on our research, systems development, sales, and general managerial resources. We may not be able to
manage this growth successfully. The continued expansion effort on which our future growth depends has inher-
ent risks, such as the following: any new or enhanced services we develop might not meet the increasingly sophis-
ticated needs of our current or potential clients; we might not succeed in developing new or enhanced services;
and we might not succeed in entering new geographical markets.

If we are unable to maintain the integrity and reliability of our data, our business could be harmed. Our suc-
cess depends on our clients’ confidence in the comprehensiveness, accuracy, and reliability of the data we provide.
We believe that we take adequate precautions to safeguard the completeness and accuracy of our data and that the
information is generally current, comprehensive, and accurate. But the task of establishing and maintaining this
quality while we grow is challenging. We cannot guarantee that we can sustain those efforts. If we cannot main-
tain the quality of our data, we could experience reduced demand for our services and could be exposed to law-
suits claiming damages resulting from inaccurate data.

We may not be able to adapt to the rapid technological changes to the Internet and Internet products. To be
successful, we must adapt to the rapid technological changes to the Internet and Internet products by continually
enhancing our Web site and introducing and integrating new services and products to capitalize on the technolog-
ical advances in the Internet. Although in the next year we expect to migrate all of our information products to a
web-based platform, this process is costly and we cannot assure you that we will be able to successfully integrate
our  services  and  products  with  the  Internet’s  technological  advances. The  collection, storage, management  and
dissemination of commercial real estate information from a centralized database on the Internet is a recent and
evolving development. Our market is characterized by rapidly changing technologies, evolving industry standards,
increasingly sophisticated customer needs and frequent new product introductions. These factors are exacerbated
by the rapid technological change experienced in the computer and software industries. We could incur substantial
costs if we need to modify our services or infrastructure in order to adapt to these changes. If we incurred signif-
icant costs without adequate results or we are unable to adapt to rapid technological changes, it could have a mate-
rial adverse effect on our business.

Our increasing use of the Internet and the World Wide Web exposes us to regulatory and other uncertainties.
Most of our clients currently receive their CoStar data via the Internet. We are in the process of making substan-
tially all our services accessible through a standard Web-browser format. This exposes us to various uncertainties
arising from the future course of development of the Internet and the World Wide Web. Governments in the United
States and abroad might adopt laws or regulations applicable to Internet commerce that could harm our business
by, for example, regulating our transmissions over the Internet or exposing our business to new taxes in various

17

jurisdictions. User concerns about the privacy and security of Internet-distributed communications might impede
the growth of our business. We may need to expend substantial resources to protect against security breaches on
our Web site or in our Internet communications.

We cannot assure you that our Internet products will achieve market acceptance. We intend to continue to
increase our reliance on the Internet for delivery of our services and products. As a result, our future profitability
will increasingly rely upon the use of our information services and transaction support products on the Internet.
Our ability to obtain market acceptance for our Internet products will depend on the following factors: our ability
to transition our customers from the use of our services and products on CD-ROM to the use of these services and
products on the Internet in a timely and efficient manner; our customers acceptance of, and their ability to adapt
to the use of, our existing and future services and products on the Internet; and our ability to anticipate and adapt
to the changing Internet market. If our Internet-based information services or transaction support products are not
received favorably by our current customers, their use of our other products may be negatively affected or cause
new customers to choose a competitive service over ours.

Unsatisfactory  Internet  performance,  interruption  or  failure  could  have  an  adverse  effect  on  our  business.
Our business increasingly depends upon the satisfactory performance, reliability and availability of our Web site,
the  Internet  and  the World Wide Web.  Problems  with  the  Internet  or Web  may  impede  the  development  of  our
business for a number of reasons. If the number of Internet users or their use of Internet resources continues to
grow, we  may  overwhelm  the  existing  Internet  infrastructure.  Growth  in  Internet  usage  that  is  not  matched  by
comparable growth of the infrastructure supporting the Internet could result in slower response time, cause out-
right failure of the Internet, or otherwise adversely affect usage.

We may be subject to legal liability for displaying or distributing information on the Internet. Because the
content in our database is distributed to others, we may be subject to claims for defamation, negligence or copy-
right  or  trademark  infringement  or  claims  based  on  other  theories.  These  types  of  claims  have  been  brought,
sometimes successfully, against Internet services in the past. We could also be subject to claims based upon the
content that is accessible from our Web site through links to other Web sites or information on our Web site sup-
plied  by  third  parties.  Our  insurance  may  not  adequately  protect  us  against  these  types  of  claims.  Even  to  the
extent these claims do not result in liability to us, we could incur significant costs in investigating and defending
against any claims. Our potential liability for information distributed by us to others could require us to implement
measures to reduce our exposure to liability, which may require the expenditure of substantial resources and limit
the attractiveness of our service to users.

Temporary  or  permanent  outages  of  our  computers  and  software  or  telecommunications  equipment  could
have an adverse effect on our business. Our operations depend on our ability to protect our database, computers
and software, telecommunications equipment and facilities  against damage from potential dangers such  as fire,
power loss, security breaches, and telecommunications failures. Any temporary or permanent loss of one or more
of these systems or facilities from an accident, equipment malfunction or some other cause could harm our busi-
ness. Our core computer services and networking equipment are located in a climate controlled, fire and security-
protected  central  location. We  keep  off-site  backup  copies  of  all  data  contained  in  our  database, maintain  a
back-up power supply and equipment, and stockpile spare parts. These measures may not, however, adequately
protect our business.

We may be unable to enforce or defend our ownership and use of intellectual property. The success of our
business depends in large part on the intellectual property involved in our methodologies, database and software.
We  rely  on  a  combination  of  trade  secret  and  copyright  laws, nondisclosure  and  noncompetition  provisions,
license  agreements  and  other  contractual  provisions  and  technical  measures  to  protect  our  intellectual  property
rights. We cannot guarantee that we will always succeed in this effort. Our business could be significantly harmed
if we do not succeed in protecting our intellectual property. The same would be true if a court should find that our
services infringe other persons’ intellectual property rights. Any intellectual property lawsuits, in which we might
become involved, either as a plaintiff, such as in the LoopNet lawsuit, or as a defendant, could cost us much time
and money.

International expansion may result in new business risks. If we expand internationally, this expansion could
subject us to new business risks, including: adapting to the differing business practices and laws in foreign com-
mercial real estate markets; difficulties in managing foreign operations; limited protection for intellectual property 

18

rights in some countries; difficulty in accounts receivable collection and longer collection periods; cost of enforce-
ment of contractual obligations; impact of recessions in economies outside the United States; currency exchange
rate fluctuations; and potentially adverse tax consequences.

Our business depends on retaining and attracting highly capable management and operating personnel. Our
success depends in large part on our ability to retain and attract management and operating personnel, including
our President and Chief Executive Officer, Andrew C. Florance. Our business requires highly skilled technical,
sales, management, Web-development, marketing and research personnel, who are in high demand and are often
subject to competing offers. Because we are expanding rapidly, we continue to need an increased number of man-
agement and support personnel. To retain and attract key personnel, we use various measures, including multi-
year employment agreements containing confidentiality and noncompetition agreements, a stock option plan, and
incentive  bonuses  for  key  executive  officers. We  are  the  beneficiary  of  a  key  person  life  insurance  policy  on 
Mr.  Florance.  These  measures  may  not  be  enough  to  retain  and  attract  the  personnel  we  need  or  to  offset  the
impact on our business of a loss of Mr. Florance or other key employees.

If we are unable to continue to develop our sales force, it could have a material adverse effect on our busi-
ness. In order to support our growth, we need to substantially increase the size of our direct sales force. Our abil-
ity to increase our direct sales force involves a number of risks, including: the competition we face from other
companies in hiring and retaining sales personnel; our ability to integrate and motivate additional sales and sales
support personnel; our ability to manage a multi-location sales organization; and the length of time it takes new
sales personnel to become productive.

Competition  could  render  our  services  uncompetitive. The  market  for  information  systems  and  services  in
general  is  highly  competitive  and  rapidly  changing. We  believe  our  proprietary  database  and  content  compete
favorably with our competitors. However, many of our existing competitors, as well as a number of potential new
competitors, may have longer operating histories in the Internet market, greater name recognition, larger customer
bases, greater user traffic and greater financial, technical and marketing resources than us. Our competitors may
be  able  to  undertake  more  extensive  marketing  campaigns, adopt  more  aggressive  pricing  policies, make  more
attractive offers to potential employees, subscribers, distribution partners and content providers and may be able
to respond more quickly to new or emerging technologies and changes in Internet user requirements.

Cyclical downturns and consolidation in the commercial real estate industry could have an adverse effect on
our  business. Our  business  depends  on  conditions  in  the  commercial  real  estate  industry, including  businesses
that supply or invest in that industry. Changes in the commercial real estate market may affect demand for our
services.  The  traditional  economic  downturns  in  the  commercial  real  estate  industry  could  harm  our  business.
These changes could decrease renewal rates, which could have a material adverse impact on our operating results.
Also, companies in this industry are consolidating, often in order to reduce expenses. Consolidation could reduce
the number of our existing clients, reduce the size of our target market and increase our clients’ bargaining power.
Any of these factors could adversely affect our business.

If we do not generate sufficient cash flows from operations, we may need additional capital. To date, we have
financed our operations through cash from profitable operations in our established markets, the sale of our stock
and borrowing money. If we do not generate enough cash from operations to finance our business in the future, we
will need to raise additional funds through public or private financing. Selling additional stock could dilute the
equity interests of our stockholders. If we borrow money, we will have to pay interest and agree to restrictions that
may limit our operating flexibility. We may not be able to obtain funds needed to finance our operations at all or
may be able to obtain them only on unattractive terms.

Problems  with  our  software  could  impair  the  use  of  our  services. The  software  underlying  our  services  is
complex  and  may  contain  undetected  errors. We  have  previously  discovered  errors  in  our  proprietary  software.
Despite testing, we cannot be certain that errors will not be found in current versions, new versions or enhance-
ments of that software. Any errors could result in adverse publicity, impaired use of our services, loss of revenues,
cost  increases  and  legal  claims  by  customers. All  these  factors  could  seriously  damage  our  business, operating
results and financial condition.

Market volatility may have an adverse effect on our stock price. The trading price of our common stock has
fluctuated widely in the past and, like most stocks, it will continue to fluctuate in the future. The price could fluc-
tuate widely based on numerous factors, including: quarter-to-quarter variations in our operating results; changes
in analysts’ estimates of our earnings; announcements by us or our competitors of technological innovations or

19

new  services;  general  conditions  in  the  commercial  real  estate  industry;  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 Internet-related and other technology 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.

Stock ownership by executive officers and directors provides substantial influence over matters requiring a
vote  of  stockholders. Our  executive  officers  and  directors, and  entities  affiliated  with  them, beneficially  own  a
sufficient number of our outstanding common stock to exercise substantial influence over the election of directors
and other matters requiring a vote of stockholders. This concentrated ownership might delay or prevent a change
in control and may impede or prevent transactions in which stockholders might otherwise receive a premium for
their shares.

Our charter documents contain provisions that could impede third party acquisitions. Our governing corpo-
rate  documents  contain  provisions  that  could  discourage  potential  takeover  attempts  and  make  attempts  by  our
stockholders to change management more difficult. These provisions include: a requirement that stockholders give
us advance notice of certain nominations for our board of directors and of new business for any stockholder meet-
ing; a prohibition on stockholders’ calling special meetings; and a prohibition on stockholder action by written
consent. Our certificate of incorporation also allows our board of directors to issue up to two million shares of pre-
ferred stock and to fix the rights of those shares without a vote by the stockholders. The rights of holders of com-
mon  stock  may  be  harmed  by  the  rights  of  the  holders  of  this  “blank  check” preferred  stock.  If  we  issue  any
preferred stock, an outside party may find it more difficult to acquire a majority of our outstanding voting stock.
In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation
Law. Applying these provisions could delay or prevent a change in control, which could adversely affect the mar-
ket price of our common stock.

REPORT OF INDEPENDENT AUDITORS

Board of Directors
CoStar Group, Inc.

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. as of December 31,
1998  and  1999, and  the  related  consolidated  statements  of  operations, stockholders’ equity  and  cash  flows  for
each of the three years in the period ended December 31, 1999. These financial statements are the responsibility
of the Company’s management. Our responsibility is to express an opinion on these financial statements based on
our audits.

We  conducted  our  audits  in  accordance  with  auditing  standards  generally  accepted  in  the  United  States.
Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the
financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence sup-
porting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as evaluating the overall financial state-
ment presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consoli-
dated financial position of CoStar Group, Inc. at December 31, 1998 and 1999, and the consolidated results of
their operations and their cash flows for each of the three years in the period ended December 31, 1999, in con-
formity with accounting principles generally accepted in the United States.

COSTAR GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

CoStar Group, Inc. (the “Company”) has created a comprehensive, proprietary, national database of commer-
cial real estate information for metropolitan areas throughout the United States. Based on its unique database, the
Company provides information to the commercial real estate and related business community and operates within
one reportable business segment. The information is 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

CoStar Group, Inc. is a Delaware corporation and was incorporated in February 1998 to succeed its prede-
cessors, Realty  Information  Group  L.P.  (“RIGLP”)  and  OLD  RIG, Inc.  (“RIGINC”).  RIGLP  was  an  operating
entity, while RIGINC was a shell holding entity. In connection with the Company’s Initial Public Offering on July 1,
1998  (“the  Offering”), RIGLP  and  RIGINC  merged  with  the  Company  pursuant  to  the  RIG  Contribution
Agreement dated March 5, 1998. The limited partners of RIGLP (other than RIGINC) and all of the stockholders
of RIGINC received 3.03 shares of Common Stock of the Company per each limited partnership unit or share of
common stock exchanged, for a total of 5,754,017 shares. As a result of the reorganization of these entities, the
Company owned (directly or indirectly) all of the capital stock of RIGINC and all the equity of RIGLP.

The merger has been accounted for as a reorganization of entities under common control similar to a pooling
of interests. Following the merger, each shareholder of the Company maintained their exact same ownership of the
operating entity, RIGLP, as before the merger. The transfer of assets and liabilities of RIGLP and RIGINC have
been recorded at the historical carrying values. The financial statements are presented as if the Company was in
existence throughout all periods presented, as one operating entity. All share amounts have been restated to reflect
the conversion of partnership units to common stock of the Company. On January 1, 1999, RIGLP and RIGINC
were  merged  into  a  newly  formed  corporation, CoStar  Realty  Information, Inc.  (“CoStar  Realty”), a  wholly
owned subsidiary of the Company.

Additionally, the  consolidated  financial  statements  of  the  Company  include  the  accounts  of  New  Market
Systems  (“NMS”)  acquired  on  March  1, 1997, C  Data  Services, Inc.  (“CDS”)  acquired  on August  14, 1998,
LeaseTrend, Inc. (“LeaseTrend”) acquired on January 8, 1999, Jamison Research, Inc. (“Jamison”) acquired on
January  22, 1999, and ARES  Development  Group, LLC  (“ARES”)  acquired  on  September  15, 1999.  CDS  was
merged into CoStar Realty on January 1, 1999, and LeaseTrend and Jamison were merged into CoStar Realty on
December 31, 1999.

Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries after elimina-

tion of all significant intercompany transactions.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the
United  States  requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the
financial statements and accompanying notes. Actual results could differ from those estimates.

Reclassifications

Certain previously reported amounts have been reclassified to conform to the Company’s current presentation.

F-7

Revenue Recognition

Revenue from the sale of licenses is recognized on a straight-line basis over the term of the license, which is

typically from one to three years.

During 1998 and 1999, the Company recognized revenue in accordance with Statement of Position No. 97-2,
“Software Revenue Recognition,” (“SOP 97-2”). Prior to 1998, the Company recognized revenues in accordance
with Statement of Position No. 91-1, “Software Revenue Recognition.”

Significant Customers

No single customer accounted for more than 5% of our revenues as of December 31, 1999. The Company

operates solely within one business segment.

Comprehensive Income (Loss)

For the years ended December 31, 1997, 1998 and 1999, the Company’s net income (loss) reflects compre-

hensive income (loss) and accordingly, no additional disclosure is presented.

Advertising Costs

The  Company  expenses  advertising  as  incurred.  Advertising  expense  was  $398,700, $904,600, and

$1,332,000 for the years ended December 31, 1997, 1998, and 1999, respectively.

Income Taxes

Through June 30, 1998, the Company operated as a partnership for federal income tax purposes under which
income, losses, deductions and credits were allocated to and reported by the partners on their individual income
tax returns. Accordingly, no provision for income tax was recorded in the financial statements. In connection with
the Company’s initial public offering, the partnership became part of the Company and its taxable income (loss)
flowed through to the Company. Had the Company operated as a C-Corporation for the years ended December 31,
1996, 1997  and  1998, there  would  be  no  income  taxes  recorded  as  a  result  of  the  losses  for  the  periods.
Commencing  in  1998, the  Company  provides  for  income  taxes  under  the  provisions  of  Statement  of  Financial
Accounting Standards No. 109 (“FAS 109”). Deferred income taxes result from temporary differences between
the tax basis of assets and liabilities and the basis reported in the consolidated financial statements.

Stock-Based Compensation

The Company accounts for its stock-based compensation in accordance with APB No. 25, “Accounting for
Stock Issued to Employees” (“APB 25”) using the intrinsic value method. Stock-based compensation related to
options granted to non-employees is accounted for using the fair value method in accordance with the Statement
of  Financial Accounting  Standard  No.  123  “Accounting  for  Stock-Based  Compensation” (“FAS  123”).  The
Company has made pro forma disclosures required by FAS 123 for all options granted.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or
less  to  be  cash  equivalents.  Cash  equivalents  consist  of  money  market  fund  investments  and  United  States
Government Securities, substantially all of which are held with one institution. At December 31, 1998, cash of
$100,000 and $500,000 was held in escrow accounts under the conditions of a data licensing agreement and the
LeaseTrend acquisition agreement, respectively. Both amounts were paid out of escrow in 1999.

Concentration of Credit Risk and Financial Instruments

The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not
require collateral. The Company maintains reserves for credit losses, and such losses have been within manage-
ment’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.  The  carrying  value  of  the  Company’s  financial  instruments  including  cash  and  cash
equivalents, accounts receivable, accounts payable, accrued expenses and notes payable approximates fair value.

F-8

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are calculated on the straight-line

method over the following estimated useful lives of the assets:

Leasehold improvements

Shorter of lease term or useful life

Furniture and office equipment

Research vehicles

Seven years

Three years

Computer hardware and software

Three to five years

Capitalized Product Development Costs

Initial costs to develop and produce the Company’s database and software products, including direct labor,
contractors and applicable overhead are capitalized from the time technological feasibility is determined until ini-
tial  product  release.  Prior  to  technological  feasibility, such  costs  are  classified  as  software  development  and
expensed as incurred. Ongoing significant enhancements of the product are capitalized subsequent to initial prod-
uct release. 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 initial product release. Included in
amortization  is  approximately  $122,000, $160,000  and  $219,000  of  expense  related  to  the  capitalized  product
development costs for the years ended December 31, 1997, 1998 and 1999, respectively.

Intangible and Other Assets

Goodwill and other intangibles represent the unamortized excess of the cost of acquiring subsidiary compa-
nies over the fair value of such companies’ net tangible assets at the dates of acquisition. Goodwill, acquired tech-
nology, and  customer  base, which  are  related  to  the  Company’s  acquisitions  as  described  in  Note  3, are  being
amortized on a straight-line basis over periods ranging from two to ten years. The cost of photography is amor-
tized on a straight-line basis over five years.

Long-Lived Assets

In  accordance  with  Statement  of  Financial Accounting  Standards  (“SFAS”)  No.  121, “Accounting  for  the
Impairment  of  Long-Lived Assets  and  for  Long-Lived Assets  to  be  disposed  of”, management  periodically
reviews, if impairment indicators exist, the carrying value and lives of long-lived assets. For long-lived assets to
be held and used, the Company bases its evaluation on such impairment indicators as the nature of the assets, the
future economic benefit of the assets, as well as other external market conditions or factors that may be present. If
such impairment indicators are present or other factors exist that indicate that the carrying amount of the asset
may  not  be  recoverable, the  Company  determines  whether  an  impairment  has  occurred  through  the  use  of  an
undiscounted cash flows analysis of assets at the lowest level for which identifiable cash flows exist. If impair-
ment has occurred, the Company recognizes a loss for the difference between the carrying amount and the esti-
mated  value  of  the  asset. The  fair  value  of  the  asset  is  measured  using  discounted  cash  flow  analysis  or  other
valuation techniques. In addition, the Company evaluates the recoverability of enterprise goodwill by assessing
whether the book value can be recovered through expected and undiscounted cash flows.

Net Loss Per Share

Basic loss per share is based on the weighted average shares outstanding during the period. The calculation of
diluted loss per share increases the shares used in the calculation by the dilutive effects of options, unvested com-
mon  stock, warrants, and  convertible  securities.  The  Company’s  common  stock  equivalent  shares  outstanding
from stock options, unvested common stock, warrants and convertible securities are excluded from the diluted loss
per share computation, as their effect is antidilutive.

F-9

3. Acquisitions

On March 1, 1997, the Company acquired 99.3% of the outstanding shares of New Market Systems, Inc., a
California  corporation, through  the  exchange  of  44,571  shares  of  common  stock  and  payment  of  $550,000  in
cash. The Company valued the shares of common stock at $206,000 which the company estimates as the fair mar-
ket value of its common stock on the acquisition date.

On August 14, 1998, the Company acquired Houston-based commercial real estate information provider, C
Data Services, Inc. CDS was acquired in a transaction in which the former stockholders of CDS received 93,530
shares of common stock of the Company and approximately $9,000 in cash. The transaction was accounted for as
a purchase and the consideration was valued for accounting purposes at approximately $617,000 including acqui-
sition expenses.

On January 8, 1999, the Company acquired all of the common stock of LeaseTrend, Inc., a Cincinnati based
provider  of  commercial  real  estate  information, for  $4,500,000  in  cash  and  566,671  shares  of  the  Company’s
common stock. The transaction was accounted for as a purchase and the consideration was valued for accounting
purposes at approximately $9,200,000 including acquisition expenses.

On January 22, 1999, the Company acquired all of the common stock of Jamison Research, Inc., an Atlanta
based  provider  of  commercial  real  estate  information, for  $5,284,000  in  cash  and  446,637  shares  of  the
Company’s common stock. The transaction was accounted for as a purchase and the consideration was valued for
accounting purposes at approximately $10,300,000 including acquisition expenses.

On  September  15, 1999, the  Company  acquired  all  of  the  membership  interests  of ARES  Development
Group, LLC, Los Angeles based developers and distributors of ARES for ACT!, for $250,000 in cash and 33,208
shares of the Company’s common stock. The transaction was accounted for as a purchase and the consideration
was valued for accounting purposes at approximately $1,265,000 including acquisition expenses. In addition, the
acquisition agreement provides for $1,000,000 of additional consideration (in a combination of cash and stock)
that may be paid by the Company upon the achievement of certain operating goals by the members of ARES. In
February 2000, the Company issued 2,140 shares of its common stock and paid $437,500 in cash to the members
of ARES for the achievement of the first operating goal by the members of ARES.

The operations of all acquired businesses were included in the Company’s statement of operations after the
respective date of acquisitions. Except for the portion of the purchase price of acquisitions acquired with cash,
these transactions have been excluded from the statements of cash flows.

The  Company’s  unaudited  pro  forma  condensed  consolidated  statements  of  operations  for  the  year  ended
December 31, 1998 and 1999, assuming the acquisition of CDS, LeaseTrend, Jamison and ARES had been con-
summated as of January 1 of each period, is summarized as follows:

5. Line of Credit

In October 1997, the Company entered into a line of credit agreement with Silicon Valley East (a Division of
Silicon Valley Bank), and renewed the line in October 1998. The line provided for a total of $5,000,000 in bor-
rowing bearing an interest rate at the bank’s prime rate plus 1%. At December 31, 1998, no borrowings were out-
standing  under  the  line, and  the  line  expired  in  October  1999.  Interest  paid  in  1997, 1998, and  1999  totaled
$17,760, $63,263, and $0 respectively.

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 con-
nection  with  the  commitment, the  individual  contributing  partner  received  warrants  for  the  purchase  of  45,450
shares  of  Common  Stock. The  warrants  had  a  two-year  term  beyond  the  Company’s  initial  public  offering  and
provided for the purchase of an equivalent number of shares at a price of 10% less than the price of the stock sold
in  the  initial  public  offering  ($9.00  per  share).  These  warrants  were  exercised  in  total  in  February  2000. At
December 31, 1998 and 1999, no borrowings were outstanding under the commitment. Interest paid in 1998 and
1999 totaled $28,235 and $0 respectively.

Commencing in May 1995 the Company agreed to pay an investor $10,000 per month and the Chairman of
the  Company  $6,667  per  month  for  consulting  services.  During  1997  and  1998, the  Company  incurred  fees  of
approximately  $200,000  and  $82,912, respectively, related  to  such  consulting  services. These  agreements  were
terminated in connection with the Company’s initial public offering.

F-11

7. Income Taxes

The Company 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 dif-
ferences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes.
Through June 30, 1998 the Company operated as a partnership for federal income tax purposes. The Company
paid no income taxes in 1998 or 1999.

A valuation allowance has been established against the related net deferred tax assets (exclusive of deferred
tax liabilities associated with purchase accounting) due to the uncertainty of realization. The Company’s change
in  valuation  allowance  amounted  to  $958,000  and  $5,277,000  during  the  years  ended  December  31, 1998  and
1999, respectively, primarily due to an increase in net operating losses.

The Company’s provision for income taxes resulted in effective tax rates that varied from the statutory federal

income tax rate as follows:

At December 31, 1999, the Company had net operating loss carryforwards for federal income tax purposes of
approximately $14,555,000 which expire, if unused, from the year 2010 through the year 2019. The tax benefit of
approximately  $2.0  million  of  net  operating  losses  related  to  stock  options  will  be  credited  to  equity  when  the
benefit is realized through utilization of the net operating loss carryforwards.

During  1999, the  Company  made  acquisitions  reported  using  the  purchase  method  of  accounting.  These
acquisitions included identified intangible assets, which in accordance with FAS 109, required deferred taxes and
related goodwill to be recorded. At December 31, 1999, the amount of the deferred taxes and related unamortized
goodwill was approximately $6,988,000. The deferred taxes will reverse over the life of the identified intangible
assets and related goodwill. During the year ended December 31, 1999, the reversal of the deferred tax benefit of
approximately $901,000 has been reported with the related goodwill amortization in the same amount under gen-
eral and administrative expenses.

9. Sales of Common Stock

In May 1997, the Company issued 65,000 shares of common stock valued at $300,000 to provide compensa-

tion to an officer, $150,000 of which had been accrued at December 31, 1996.

On July 1, 1998, the Company completed an Initial Public Offering of 2,500,000 shares of common stock for
$9.00 per share, and on August 9, 1998, the Company’s underwriter exercised its over-allotment option to pur-
chase an additional 375,000 shares of common stock (together, the “IPO”). Total proceeds of the IPO including
shares issued pursuant to the over-allotment option were $22,737,000, after deducting underwriting discounts and
commissions of $1,811,000 and offering expenses of $1,326,000. The Company repaid the amount owed on its
line of credit and subordinated debt to stockholder, for a total $1,650,000, out of the proceeds of the IPO.

On  May  10, 1999, the  Company  completed  a  Follow-On  Public  Offering  of  3,019,495  shares  of  common
stock (including the over-allotment option) (the “Follow-On Offering”) for $34.50 per share. Total proceeds of the
Follow-On  Offering  were  $97,411,393, after  deducting  underwriting  discounts  and  commissions  and  offering
expenses of $1,024,144.

11. Employee Benefit Plans

Option Plan

In March 1996 RIGLP adopted the 1996 Option and Purchase Plan (the “1996 Plan”), under which 606,000
shares of Common Stock 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  1996 Plan. In
connection with the IPO, all of the options granted under the 1996 Plan were replaced with options under the 1998
Plan (as defined below).

In June 1998 the Company’s Board of Directors adopted the Stock Incentive Plan (the “1998 Plan”) prior to
consummation of the IPO. The 1998 Plan provides for the grant of stock options to officers, directors and employ-
ees of the Company and its subsidiaries. Options granted under the 1998 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 1998 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
1998  Plan, all  outstanding  unexercisable  options  under  the  1998  Plan  immediately  become  exercisable.  The
Company has reserved 2,050,000 shares of Common Stock for issuance under the 1998 Plan. Unless terminated
sooner by the Board of Directors, the 1998 Plan will terminate in 2008.

During 1996 the Company adopted the disclosure provisions of SFAS No. 123. Accordingly, no compensa-
tion 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 consistent with the provisions of SFAS No. 123, Company’s
pro  forma  net  loss  and  net  loss  per  share  would  have  been  approximately  $3,337,000, $3,912,000  and
$16,824,000, and $0.58, $0.54 and $1.43 for the years ended December 31, 1997, 1998 and 1999, respectively.
Such pro forma results are not representative of the effects on operations for future years.

The weighted average fair value of options granted during 1997 was $3.36 using the minimum value option-
pricing model with the following assumptions: dividend yield 0%, risk-free interest rate of 6.00%, and expected
life  of  five  years. The  weighted  average  fair  value  of  options  granted  during  1998  was  $6.63  using  the  Black-
Scholes  option-pricing  model  with  the  following  assumptions: dividend  yield  0%, expected  volatility  of  94%,
risk-free interest rate of 5.7%, and expected life of five years. The weighted average fair value of options granted
during 1999 was $19.60 using the Black-Scholes option-pricing model with the following assumptions: dividend
yield 0%, expected volatility of 90%, risk-free interest rate of 5.0%, and expected life of five years.

The Company maintains a defined contribution retirement plan for all eligible employees. Effective January 1,
1997, the Company 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 l% and 15% of employees’ salaries, limited to a
maximum annual amount as established by the Internal Revenue Service. The Company matched 25% in 1997
and 1998, and 100% in 1999 of employee contributions up to a maximum of 6% of total compensation. Amounts
contributed  to  the  401(k)  by  the  Company  to  match  employee  contributions  for  the  years  ended  December  31,
1997, 1998, and 1999 were approximately $28,000, $39,000 and $364,000, respectively.

12. Subsequent Events

On February 10, 2000, the Company acquired all of the common stock of COMPS.COM, Inc., a San Diego
based  provider  of  commercial  real  estate  information, for  $49,015,905  in  cash  and  2,258,738  shares  of  the
Company’s Common Stock. The acquisition has been accounted for using purchase accounting and has been val-
ued at approximately $102,000,000 for accounting purposes. The purchase price was allocated primarily to cash,
acquired technology and other intangibles, which will be amortized over a period of 2 to 10 years.

The pro forma unaudited results of operations for the year ended December 31, 1999 assuming the purchase
of  COMPS.COM, Inc., had  been  consummated  as  of  January  1, 1999  and  as  adjusted  for  the  amortization  of
intangibles and the elimination of interest charges, would be as follows:
