We are pleased with our operating performance

CoStar’s strategy is to provide commercial 

real estate professionals with critical knowledge 

to complete transactions, by offering the most 

up-to-date, comprehensive, and standardized 

information available on U.S. commercial real

estate. We worked hard last year to supply our

for 2000. Revenues for the year ended December

31, 2000, were $58.5 million compared to $30.2

million for 1999, an increase of $28.3 million, or 

93 percent. The revenue growth was principally a

result of strong demand for our quality information

products in our existing markets. In addition, CoStar’s

operations benefited from the strategic acquisition

information, data hosting for clients’ Web sites,

decision support, contact management, tenant

information, property data integration, property

marketing solutions, and industry news.

Strategic Acquisitions Completed

COMPS.COM was acquired in February, 2000,

and aggressive steps were taken to integrate the

Comps operations into CoStar’s sales, marketing,

research, customer service, and administrative

functions. In 2000, Comps, Inc., contributed a total

of $15.5 million to CoStar’s revenues and by the

Critical Mass Achieved

Comps carried a $2.0 million monthly burn rate at

acquisition in February 2000. By March 31, 2001,

Comps achieved positive cash flow, a significant

financial achievement.

The addition of Comps’ information to the 

CoStar database appreciably expanded our

research coverage and enhanced the value of 

our products. The Comps data was an essential
component in the creation of CoStar Exchange(cid:2),
since CoStar COMPS(cid:3) data supplies historical price
points for properties and makes CoStar Exchange(cid:2)

a vital on-line market for buyers and sellers. 

CoStar COMPS remains the only national source 

for verified comparable sale information.

In November, 2000, CoStar acquired First Image

Technologies and its Metropolis software system

that combines commercial real estate data from

multiple information providers into a comprehensive

resource through a single desktop interface. With

the highest customer satisfaction levels CoStar has

found of any technology currently used by commer-

cial real estate professionals in Southern California,

CoStar enhanced our databases’ quality and

comprehensiveness by integrating data from

acquired companies and expanding market coverage

through organic growth. With the critical mass we

achieved in research coverage during 2000, we

believe we now offer more than twice the content

of any competitor.

As of December 31, 2000, CoStar’s databases

included more than 20 billion square feet or 800,000

properties, 583,000 sale comparables, 59,000

properties for sale, 968,000 digital images, and

more than 1 million tenants. In addition, our editorial

team is one of the most prolific in the industry, 

having published more than 9,600 news stories, 

a significant increase over 1999 when CoStar 

published approximately 5,500 articles.

New Products Introduced

With a national information platform principally 

in place, CoStar is utilizing our database content to

produce powerful and innovative new products.

Exchange(cid:2) now has more than 200 subscribing

firms and an annual revenue run rate in excess 

of $1,000,000. The number of properties listed

increased to a total of 61,500 currently, with a value

of $74 billion, an increase from 44,000 listings, or

$50 billion, at launch in June, 2000.

In 2000, it became clear that commercial real

estate firms needed a cost effective solution to

market their properties on the Web and CoStar was

able to rapidly design an Internet based marketing
tool to respond to their needs. CoStar Connect(cid:2),

launched in March, 2001, is a service that licenses

CoStar’s technology and content to commercial real

estate firms to market their property listings on

their corporate Web sites. Within the first month of

launch, more than 30 firms subscribe to the serv-
ice. CoStar Connect(cid:2) allows brokers and property

owners to significantly reduce the time and expense

of building property listing functionality into their

corporate Web sites. Based on our national research

(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. is the leading provider of information services to the U.S. commercial real estate industry.
CoStar’s suite of products offers customers access via the Internet to the most comprehensive, verified database
of commercial real estate information in over 50 U.S. markets.

Since its founding in 1987 and its subsequent incorporation in Delaware in 1998 to succeed its predecessor
companies, CoStar’s strategy has been to provide commercial real estate professionals with critical knowledge to
complete transactions, by offering the most up-to-date, consolidated and standardized information on U.S. com-
mercial real estate. CoStar delivers its content to customers through ten distinct products and services. Our wide
array of digital service offerings includes a leasing marketplace, a selling marketplace, sales comparable informa-
tion, data hosting for clients’ web sites, decision support, contact management, tenant information, property data
integration, property marketing and industry news. Today, we are creating a centralized digital marketplace where
the commercial real estate industry and related businesses can continuously interact and easily facilitate transac-
tions over the Internet due to efficient exchange of accurate and standardized information supplied by CoStar.

We have five 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;  proprietary  technology
including in-house product development; a broad suite of digital products and services; 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 to grow the database, we have obtained and assimilated over 50 proprietary databases. The database now
contains information on more than 20 billion square feet of commercial real estate, over one million tenants and
covers more than $70.6 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. Each transaction has multiple information requirements,
and in order to facilitate transactions, industry participants must have extensive, accurate and current information.
Members of the commercial real estate and related business community require daily access to current data such
as rental rates, vacancy rates, tenant movements, supply, new construction, 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  commercial  real  estate  professionals  spent  40%  of  their
workday collecting and analyzing information on the real estate market. There is a strong need for an efficient
marketplace, where commercial real estate professionals can exchange information, evaluate opportunities using
national standardized 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 managers

• Design and construction professionals

• Real estate developers

• Government agencies’ staff members

• Mortgage-backed security issuers

• Appraisers

• Reporters

• Tenant vendors

• Real estate investment trust managers

• Building services vendors

• Investment bankers

• Commercial bankers
• Investors and asset managers

• Communications providers

• Insurance companies’ managers
• 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  develop  software  to  analyze  the  information  they  have  inde-
pendently gathered. This highly fragmented methodology has resulted in duplication of effort in the collection and
analysis  of  information, excessive  internal  cost  and  the  creation  of  non-standardized  data  containing  varying
degrees of accuracy and comprehensiveness, thus spawning a formidable information gap.

The  creation  of  an  efficient  digital  marketplace  for  commercial  real  estate  requires  an  infrastructure  of  a
national, standardized database, accurate and comprehensive research capabilities and intensive, real-time partici-
pant interaction. By combining its extensive database, approximately 700 experienced researchers, technological
expertise and broad customer base, CoStar believes that it has created the platform for this national exchange. Our
infrastructure combined with Internet technology has allowed CoStar to develop a truly centralized and interactive
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 func-
tions that are unavailable in traditional media. These features 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 14 years building and acquiring a proprietary database of commercial real estate informa-

tion, which includes leasing, sales, comparable sales, tenants, demand statistics and digital images.

As of December 31, 2000, our proprietary database contained:

• more than 20 billion square feet of U.S. commercial real estate;

• over 800,000 properties;

• over 2.3 billion square feet of space available;

• approximately 59,000 properties for sale;

• over 1 million tenants occupying commercial real estate space;

• more than 583,000 sales transactions valued at over $750 billion; and

• over 968,000 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 utilizing a multi-faceted research process. In
2000, our researchers drove approximately one million miles, conducted hundreds of thousands of on-site build-
ing inspections, examined more than 60 million public records and interviewed approximately one million ten-
ants, owners and brokers.

Research  Department. As  of  December  31, 2000, approximately  700  commercial  real  estate  research
professionals conducted research for CoStar. Every research employee undergoes an extensive training program
to  maintain  consistent  research  methods  and  processes.  Our  researchers  collect  and  analyze  commercial  real
estate information through millions of phone calls, e-mails, Internet updates and faxes each year, in addition to
field inspections, public records review, news monitoring and direct mail. Each researcher is responsible for main-
taining the accuracy and reliability of the database. As part of their update process, researchers develop coopera-
tive  relationships  with  industry  professionals  that  allow  them  to  gather  useful  information.  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 and report transactions to our researchers.

CoStar  has  an  extensive  field  research  effort  that  permits  physical  inspection  of  properties  in  order  to  find
additional inventory, photograph properties and verify existing information. 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. Each CoStar truck uses wireless technology to track and transmit field data. A dis-
patch center in the Company’s Bethesda office manages the entire day-to-day field operations while using track-
ing software to monitor each researcher’s progress. As of December 31, 2000, CoStar had 39 trucks used by field
researchers in markets throughout the United States. The site inspection consists of photographing the building,
measuring the building (if necessary), counting parking spaces, assessing property condition and construction, and
gathering  tenant  information.  Certain  researchers  canvass  properties, interviewing  tenants  suite  by  suite.  Other
researchers  conduct  fieldwork  in  county  courthouses  and  public  records  offices.  In  addition, many  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, and  licensing
agreements with these entities provide for our use of a portion of their national property ownership information in
the enhancement and development of various CoStar services.

Management and Quality Control Systems. In 2000, we enhanced both our 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  space  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; 

• performing periodic research audits and field checks to determine if we correctly canvassed all buildings; 

• providing training and retraining to our research professionals to ensure accurate data compilation; and 

• compiling measurable performance metrics for research teams and managers for feedback on data quality.

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.

Proprietary Technology

In-House Product Development and Information Technology Team. As of December 31, 2000, CoStar had a
staff of approximately 65 product development and information technology professionals who focused on devel-
oping  and  creating  enhanced  products, designing  systems  to  ensure  continuous  improvement  in  data  quality,
improving the speed of data delivery, and building infrastructure capable of supporting CoStar’s comprehensive
database  and  image  library.  In  2000, this  team  completed  the  development  of  several  new Web  products  and
enhanced other Web enabled software products that use the Internet for delivery of content and digital images. On
an ongoing basis, these professionals make modifications to internal applications to implement efficiencies and
controls  that  ultimately  produce  quality  improvements  to  the  database.  They  regularly  implement  product
enhancements, including  expanded  features  and  new  graphic  design.  To  increase  the  speed  of  data  collection,
quality control review and data delivery, the product development and information technology team makes regular
adjustments to internal systems. In addition, this team is responsible for developing the infrastructure to appro-
priately support a database with the size and complexity of CoStar’s database.

3

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  Property(cid:3). CoStar  Property  delivers  to  subscribers  a  complete  inventory  of  office  and  industrial
properties and has fostered the development of our 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  community, including  non-CoStar  sub-
scribers, utilize  CoStar  Property  extensively  to  market  their  properties.  Subscribers  can  query  CoStar  Property
with any combination of pertinent criteria, combining any of approximately one hundred data fields from cate-
gories such as building size, location, building characteristics, space availability, ownership, 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 customiz-
able  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 determine the feasibility of a specific
space for the user’s needs. Our clients also use CoStar Property to analyze market conditions by calculating cur-
rent vacancy rates, absorption rates or average rental rates.

CoStar Tenant(cid:3). CoStar Tenant is a detailed business-to-business prospecting and analytical tool for com-
mercial  real  estate  professionals.  CoStar  Tenant  delivers  detailed  information  profiling  the  tenants  occupying
commercial buildings by tracking tenants throughout the United States. 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 underly-
ing 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(cid:2). CoStar  COMPS  is  a  tool  for  lenders, brokers, appraisers, investors  and  corporate  real
estate  executives  who  need  to  research  property  comparables, identify  market  trends, expedite  the  appraisal
process, support  property  valuations, and  prospect  customers  using  the  database  of  buyers, sellers  and  brokers.
CoStar COMPS provides comprehensive, national information on comparable sales information in the commer-
cial real estate industry. This service is provided 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 pro-
prietary database of comparable sale information using multiple search parameters, including location, property
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  Exchange(cid:3). CoStar  Exchange  is  an  on-line  marketplace  for  the  buying  and  selling  of  commercial
properties. As of December 31, 2000, the database contained approximately 59,000 commercial properties for sale
with a combined asset value in excess of $70.6 billion. In the second quarter of 2000, we began distributing that
information in a broker-centric model through a secure Web-based browser where sellers and brokers of proper-
ties are able to list extensive information about their properties for sale on the site at no cost. The site affords an
efficient means for these sellers to reach a large universe of potential buyers. Sellers of investment-grade proper-
ties have the additional option of selecting limited, secure distribution of their properties in order to address con-
fidentiality requirements. The CoStar Exchange service integrates the content developed through years of research
under the CoStar Property, CoStar Tenant, CoStar COMPS and other CoStar services.

CoStar Connect(cid:3). CoStar Connect was released during the first quarter of 2001 and allows commercial real
estate firms to license CoStar’s technology and content to market property listings on their corporate web sites.
This service offers clients access to CoStar’s content and digital images in a service that seamlessly updates and
manages the client’s on-line property information. It enables commercial real estate professionals to enhance the
quality and depth of their listing information by incorporating data fields from CoStar’s national database. CoStar
Connect  also  adds  new  technology  capabilities  to  company  web  sites  such  as  search  engines, tailored  space
queries, space calculators, sophisticated mapping and 360° virtual tours.

CoStar  Marketplace(cid:3). 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 Web  site.  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(cid:3). Our Web site, our CoStar services and our e-mail news dispatches have become an accepted
source  of  reliable  industry  news.  In  2000, we  published  over  9,200  news  stories.  Our  newswire  feature  keeps
clients informed of late-breaking commercial real estate news such as deals signed, acquisitions, ground breakings
and other features.

CoStar  Advisory(cid:3). CoStar Advisory  is  an  electronic  report  that  provides  in-depth  analyses  of  changing
trends in vacancy rates, tenant movements, supply, new construction, absorption rates, and other important market
metrics at the metropolitan, market and sub-market levels. CoStar Advisory is currently available for the Atlanta
and  Dallas  markets.  Certain  of  the  analytic  tools  within  CoStar Advisory  are  also  available  within  CoStar
Property, which allow users to perform sophisticated analyses of underlying market conditions and trends when
making decisions involving commercial real estate.

Metropolis(cid:3). As a result of our November 2000 acquisition of First Image Technologies, Inc., we now offer the
Metropolis software system, a single interface that combines commercial real estate data from multiple information
providers into a comprehensive resource. The metropolis software allows a user to input a property address and then
view  detailed  information  on  that  property  from  multiple  information  providers, including  CoStar  products. This
technology offers commercial real estate professionals a simple and convenient solution for integrating a wealth of
third-party information and proprietary data, and is currently available for the Southern California market.

CoStar ARES 2000(cid:3). CoStar ARES 2000 is 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 productivity system by providing commercial real estate elements that are not provided by ACT!. Users of
CoStar ARES 2000 can import data from other CoStar services into CoStar ARES 2000.

Clients

We  draw  clients  from  across  the  commercial  real  estate  and  related  business  community.  Commercial  real
estate brokers have traditionally formed the largest portion of CoStar clients, however, we also provide services to

As of December 31, 2000, no single client accounted for more than 5% of our revenues. We do not have a sig-

nificant backlog and do not believe that backlog is a meaningful indicator of our future results.

Sales and Marketing

As  of  December  31, 2000, we  had  over  170  sales, marketing  and  customer  support  employees, with  the
majority  of  our  direct  sales  force  located  in  field  sales  offices.  Our  sales  teams  are  primarily  geographically
focused and located in over 20 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 sales
force is responsible for selling to new prospects, renewing existing client contracts and identifying cross-selling
opportunities.

Our field sales people primarily focus in Information Solutions or eMedia. The Information Solutions sales
personnel focus on selling information services such as CoStar Exchange, CoStar Property, CoStar Tenant, CoStar
COMPS and Metropolis. Many of these salespeople have significant commercial real estate experience, allowing
them  to  take  a  consultative  sales  approach. Within  this  group, we  have  a  major  accounts  team  which  focuses
solely on the Company’s largest clients. The eMedia sales personnel sell CoStar Connect, on-line advertising on
our Web site and advertising space in the CoStar Property and CoStar Tenant regional newswires. Many of these
sales people have an advertising sales background or experience in commercial real estate. Our sales strategy is to
aggressively attract new clients, while providing ongoing incentives for existing clients to subscribe to more of
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  customer  service  and  support  staff  is  charged  with  installing  and  training  our  client  base, as  well  as
ensuring high client satisfaction by providing on-going support. The customer service and support staff handles all
facets of customer relations including billing questions, research questions and routine technical issues, and has
primary, front-line responsibility for customer care.

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. Our direct marketing efforts include direct mail, e-mail and telemarketing, and make extensive
use  of  our  unique, proprietary  database.  Once  we  have  identified  a  prospective  client, we  have  found  the  most
effective sales method is a service demonstration. Our advertising includes traditional print advertising, Internet
banners and private network banners. We use various forms of advertising for brand identity, message reinforce-
ment, and potential client identification. We also attend industry trade shows and seminars to reinforce our rela-
tionships 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 intensely competitive and rapidly changing. In the commercial real estate
industry, the principal competitive factors for commercial real estate information are:

• quality and depth of the underlying databases; 

• price; 

• 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; and 

• capital resources.

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

• on-line 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, including regional providers and smaller local providers,

and national print publications such as Black’s Guide;

• consortiums of real estate companies formed to explore opportunities in technology; 

• locally based real estate boards or associations sponsoring property listing services;

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

• public record providers.

As  the  digital  real  estate  marketplace  develops, additional  competitors  (including  companies  which  could
have greater access to data, 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 our-
selves 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, trademark and other laws;

• nondisclosure, noncompetition and other contractual provisions with employees and consultants;

• 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

7

databases that perform the same function as ours. We believe, however, that it would be 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
content, images and software. In addition, the license agreements prohibit the unauthorized reproduction or trans-
fer of the information and software we license.

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

We have filed trademark applications to register trademarks for a variety of names for the CoStar products
and other marks, and have obtained registered trademarks for “CoStar” and “COMPS.” In addition, we have filed
a patent application covering certain of our methodologies and software.

On September 30, 1999, CoStar filed suit against LoopNet, Inc., 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
Web site 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 ownership before posting any photo-
graph 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 December 31, 2000, we employed 974 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 in Bethesda, Maryland, occupies approximately 60,000 square feet under a lease
that expires on March 14, 2010. We believe that our Bethesda, Maryland, facility will be adequate to meet our
requirements for our headquarters for the foreseeable future.

In  addition  to  our  Bethesda, Maryland, facility, our  research  operations  are  headquartered  in  San  Diego,
California and Mason, Ohio. Additionally, we lease office space in a variety of other locations, which are generally
field sales offices. These locations include, without limitation, the following: New York; Los Angeles; Chicago;
San Francisco; Boston; Newport Beach; Philadelphia; Houston; Atlanta; Phoenix; Southfield, Michigan; Cranford,
New  Jersey;  Charlotte, North  Carolina;  Ft.  Lauderdale, Florida;  Seattle;  Denver; Austin;  Dallas;  Sacramento,
California; and Tampa, Florida.

Item 3 Legal Proceedings

We are currently and from time to time are involved in litigation incidental to the conduct of our business.
We are not a party to any lawsuit or proceeding that, in the opinion of our management, is likely to have a mate-
rial adverse effect on our financial position or results of operations.

Item 4 Submission of Matters to a Vote of Security Holders

We did not submit any matters to a vote of our security holders during the quarter ended December 31, 2000.

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

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations con-
tains “forward-looking statements,” which involve many risks and uncertainties that could cause actual results to
differ materially from these statements. Factors that could cause or contribute to such differences include, but are
not  limited  to, successful  adoption  of  our  products, competition, general  economic  conditions, changes  in  the
commercial  real  estate  industry, managerial  execution, customer  retention, development  of  our  sales  force,
employee  retention  and  our  ability  to  adapt  to  technological  changes.  More  information  about  potential  factors
that  could  cause  actual  results  to  differ  materially  include, but  are  not  limited  to, those  stated  below  under  the
heading “Risk Factors.” All forward-looking statements are based on information available to us on the date of
this filing, and we assume no obligation to update such statements. The following discussion should be read in
conjunction with our filings with the Securities and Exchange Commission and the consolidated financial state-
ments included herein.

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, data hosting for clients’ Web sites, contact
management, property data integration 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.COM, Inc. (“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, geographic expansion in the U.S. and international markets, strategic acquisitions and working
capital and general corporate purposes.

From 1994 through 2000, 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 Research, Inc. In September, 1999, we acquired ARES, a Los Angeles
based developer and distributor of ARES for ACT!. In February, 2000, we acquired Comps. In November, 2000,
we acquired First Image Technologies. The more recent acquisitions are discussed 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, 2000, 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, Boston, Houston, San
Diego, Phoenix, Denver and Florida. These regions provide us with substantial cash flow, which we reinvest into
the business. Emerging regions are those in the process of becoming established, and require substantial invest-
ment until such time that the revenue for the region exceeds the operating costs for the region. Since our inception,
the development of our business has required substantial investments for the expansion of services and the estab-
lishment 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
and expansion of existing services across current markets and we may have geographic expansion in the United
States  and  international  markets  in  the  future.  Therefore, while  we  expect  operations  in  existing  established
regions to remain profitable and provide substantial funding, we expect our overall expansion plans to generate
losses and negative cash flow from operations during the next year.

11

Although our services continue to expand, our CoStar Property, CoStar Tenant and CoStar COMPS services
currently  generate  the  largest  portion  of  our  revenue. The  CoStar  Property, CoStar Tenant  and  CoStar  COMPS
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 generally 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 generally exceeds 90% on an annual basis. However, recently many telecommuni-
cations companies (which represented approximately 6% of our revenues at their peak) have discontinued or cur-
tailed  their  operations.  This  has  resulted  in  an  increased  number  of  cancellations  of  our  services  by  these
telecommunications companies. These cancellations, together with other factors, could result in a lower renewal
rate for our services over the next twelve months.

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 1998 through 2000 is derived from the audited financial statements of us and of our predecessor com-
panies for those years.

Comparison of Year Ended December 31, 2000 and Year Ended December 31, 1999

Revenues. Revenues grew 93% from $30.2 million in 1999 to $58.5 million in 2000. This increase resulted
principally from growth in our client base for the regions we served, expansion of our services in existing regions
and the acquisition of Comps. Revenues from regions we considered established as of December 31, 2000 grew
from approximately $22.5 million in 1999 to approximately $31.6 million in 2000, an increase of 40%. Comps con-
tributed $15.5 million to revenues for 2000. Comps revenue grew approximately 30% in 2000 after the acquisition.

12

Gross  Margin. Gross  margin  increased  from  $17.0  million  in  1999  to  $28.3  million  in  2000. While  gross
margin increased in total, as a percentage of revenues it decreased from 56% to 48%. The increase in gross mar-
gin amounts resulted principally from significant revenue growth from established regions and the acquisition of
Comps. The decline in gross margin percentages resulted from lower gross margin percentages in Comps products
and  an  increase  in  purchase  price  amortization  from  the  LeaseTrend, Jamison, ARES, Comps  and  First  Image
Technologies acquisitions. This amortization increased from $777,000 in 1999 to $4.8 million in 2000.

Selling  and  Marketing  Expenses. Selling  and  marketing  expenses  increased  from  $18.0  million  in  1999  to
$37.6 million in 2000 and increased as a percentage of revenues from 59% in 1999 to 64% in 2000. Selling and
marketing expenses increased as a result of continued expansion of the sales organization and marketing efforts
required  for  growth, particularly  in  emerging  and  acquired  regions.  In  addition, these  expenses  increased  as  a
result of the non-recurring marketing costs surrounding the launch of our CoStar Exchange product, which began
to decline after the second quarter of 2000, and ended during the fourth quarter of 2000. 

Software  Development  Expenses. Software  development  expenses  increased  from  $1.1  million  in  1999  to
$3.9 million in 2000 and increased as a percentage of revenues from 4% in 1999 to 7% in 2000. The increase in
expenses  reflects  development  costs  for  the  increased  number  of  products  we  now  support  including  CoStar
COMPS and Costar Exchange.

General and Administrative Expenses. General and administrative expenses increased from $11.1 million in
1999  to  $27.1  million  in  2000  and  increased  as  a  percentage  of  revenues  from  37%  in  1999  to  46%  in  2000.
General and administrative expenses increased due to the hiring of new employees to support our expanded oper-
ations  and  client  base  and  also  the  increase  in  employees  due  to  the  acquisition  of  Comps.  During  2000, we
recruited and hired four senior level executives.

Purchase Amortization. Purchase amortization increased from $2.2 million in 1999 to $8.9 million in 2000.

Purchase amortization increased primarily due to the acquisition of Comps.

Acquired In-Process Development. Acquired in-process development costs of $5.8 million in 2000 consist of

in-process development costs written off as part of the Comps acquisition.

Other Income, Net. Interest and other income increased from $3.1 million in 1999 to $3.3 million in 2000.
This increase was primarily a result of a full year of interest earned on the proceeds from the follow-on public
offering.

Income Tax Benefit. An income tax benefit of $2.0 million in 2000 is a result of the reversal of the deferred tax

liability in connection with the amortization of identified intangible assets established during recent acquisitions.

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.

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
margin percentages resulted from costs related to the 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 acquisitions of $777,000.

Selling  and  Marketing  Expenses. Selling  and  marketing  expenses  increased  from  $6.9  million  in  1998  to
$18.0 million in 1999 and increased as a percentage of revenues from 50% in 1998 to 59% in 1999. Selling and
marketing expenses increased as a result of the cost of the acquired sales organizations and 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.

13

Software Development Expenses. Software development expenses increased 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 from $4.9 million in
1998  to  $11.1  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 our expanded oper-
ations and client base, as well as the increased administrative costs in a public company.

Purchase  Amortization. Purchase  amortization  increased  from  $305,000  in  1998  to  $2.2  million  in  1999.

Purchase amortization increased primarily due to the acquisition of Jamison, LeaseTrend and ARES.

Other Income, Net. 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.

Acquisitions

LeaseTrend. On  January  8, 1999, we  acquired  all  of  the  outstanding  capital  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 our 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.

14

Jamison  Research. On  January  22, 1999, we  acquired  all  of  the  outstanding  capital  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 our common stock. The transaction was accounted for as a purchase and the consider-
ation was valued for accounting purposes at approximately $10.3 million including acquisition expenses. 

ARES  Development  Group,  LLC. On  September  15, 1999, we  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 our common stock. The transaction was accounted for as a purchase and the initial
consideration was valued for accounting purposes at approximately $1,265,000 including acquisition expenses. In
addition, the acquisition agreement provided for $1,000,000 of additional consideration (in a combination of cash
and  stock)  to  be  paid  by  CoStar  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. In October 2000, we issued an
additional 2,196 shares of our common stock and paid an additional $437,500 in cash to the members of ARES for
the achievement of the second (and final) of the operating goals by the members of ARES.

Comps. On February 10, 2000, we acquired all of the outstanding capital stock of Comps, a San Diego based
provider of commercial real estate information, for $49,015,905 in cash and 2,259,034 shares of the Company’s
common stock. The acquisition has been accounted for using purchase accounting and has been valued at approx-
imately $101,379,000 for accounting purposes. The purchase price was allocated primarily to cash, acquired data-
base technology and other intangibles, which will be amortized over a period of 2 to 10 years. In connection with
the purchase of Comps, $5,812,000 of the purchase price was allocated to purchased in-process development, and
expensed  upon  acquisition  because  the  technological  feasibility  of  products  under  development  had  not  been
established and no future alternative use existed. The acquired in-process development was analyzed through an
independent third-party valuation using the expected cash flow approach.

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 CoStar. The cash portion of the purchase price was
obtained by CoStar from the proceeds from the sale of its common stock in a follow-on public offering in May,
1999. We have made 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.

During the fourth quarter of 2000, Comps reached the cash flow breakeven point as a result of the steps we
have taken to eliminate operating losses and negative cash flow, and we expect to have positive cash flow in 2001
from Comps. CoStar will continue to experience significant charges to operations for the amortization of intangi-
ble assets resulting from the acquisition.

First  Image  Technologies. On  November  9, 2000, CoStar  completed  the  acquisition  of  First  Image
Technologies, Inc. The  primary  asset  of  First  Image  is  the  Metropolis  software  system, a  single  interface  that
combines  commercial  real  estate  data  from  multiple  information  providers  into  a  comprehensive  resource. We
acquired  all  of  the  outstanding  capital  stock  of  First  Image Technologies, Inc.  for  approximately  $665,000  in
cash and 9,424 shares of our common stock. The transaction was accounted for as a purchase and the initial con-
sideration was valued for accounting purposes at approximately $950,000 including acquisition expenses. In addi-
tion, the  acquisition  agreement  provides  for  $950,000  of  additional  consideration  (in  a  combination  of  cash  and
stock) to be paid by CoStar upon the achievement of certain operating goals by the sole stockholder of First Image.

Liquidity and Capital Resources

Our cash and cash equivalents balance was $47,101,242 at December 31, 2000, a decrease of $46,972,885
from $94,074,127 at December 31, 1999. This decrease was due principally to the cash used for the acquisition of

15

Comps in February of 2000, cash used in operating activities, $11,493,570 in purchases of property and equipment,
$1,349,236  in  purchased  building  photography  and  debt  repayments  of  $4,531,000.  During  the  year  ended
December 31, 2000, we financed our operations and growth through cash flow from the established regions and the
proceeds  of  the  follow-on  offering.  Net  cash  used  in  operations  for  the  year  ended  December  31, 2000  was
$26,846,265  compared  to  net  cash  used  in  operating  activities  of  $7,476,662  for  the  year  ended  December  31,
1999. This  was  a  direct  result  of  expenditures  required  for  the  expansion  in  emerging  and  acquired  regions, the
development and launch of new services and the acquisition of Comps. We continue to experience overall operat-
ing losses as a result of our recent expansion into emerging and acquired regions, while established regions con-
tinue to generate positive cash flow from operations.

Net  cash  used  in  investing  activities  amounted  to  $17,697,603  for  the  year  ended  December  31, 2000,
including  $3,071,000  (net  of  acquired  cash)  for  the  acquisition  of  Comps  and  First  Image  Technologies.
Additional investing activities included capitalized product development costs, purchased building photography
and purchased property and equipment, consisting principally of leasehold improvements, computers 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 headquarters, and have commitments for rent payments ranging from
approximately $2,688,000 to $3,989,000 annually over the next ten years. We currently have no material com-
mitments 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.

During  the  year  ended  December  31, 2000, we  experienced  significant  losses  and  negative  operating  cash
flow as a result of the expansion in emerging regions, expansion of services in established regions, costs for the
introduction  of  new  products  and  the  acquisition  of  Comps.  Some  of  these  costs  are  non-recurring, and  the
remainder are generally fixed operating costs, which are not expected to directly increase as a result of growth in
revenue. As the Company emerges from a period of rapid product and geographical expansion, in 2001 we expect
continued sequential quarterly growth in revenue and a fixed or declining overall operating cost structure. As a
result, we expect reductions in the level of operating losses and negative operating cash flow during 2001.

Based on current plans, we believe that our available cash combined with positive cash flow from our estab-

lished regions should be sufficient to fund our operations for at least the next two years.

Through June 30, 1998, we operated as either a Subchapter S corporation or a limited partnership, and we
were not subject to corporate income taxes. After June 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. In addition, we have recorded a valuation allowance for the portion of the deferred
tax assets related to tax loss carryforwards. We do not expect to benefit substantially from tax loss carryforwards
generated prior to July, 1998.

We do not believe the impact of inflation has significantly affected our 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 2001 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 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, management’s  plans, goals  and
objectives for future operations and growth and markets for stock. The sections of this Report, which contain for-
ward-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

16

addition to those discussed in “Risk Factors,” could affect our future results and could cause those results or other
outcomes  to  differ  materially  from  those  expressed  or  implied  in  our  forward-looking  statements: competition;
technological innovation by competitors; general economic conditions; events that affect commercial real estate;
customer retention; business combinations and strategic alliances by other industry participants; managerial execu-
tion;  development  of  our  sales  force;  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 investing in expanding our operations and new
services and, therefore, expect to sustain substantial losses during the next twelve months. Our ability to earn a
profit will largely depend on our ability to manage our growth, and to generate profits from services that exceed
our investment in geographic expansion and new services. In addition, our ability to earn a profit or to increase
revenues could be affected by the factors set forth below. 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: competition; 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, brand enhancement
and  marketing  promotional  activities;  managerial  execution;  client  training  and  support  activities;  the  develop-
ment  of  our  sales  force;  loss  of  clients  or  revenues;  consolidation  in  the  real  estate  industry;  changes  in  client
budgets; or our investments in other corporate resources.

We may not be able to attract and retain clients. Our success and revenues depend on attracting and retain-
ing subscribers to our services. The CoStar Property, CoStar Tenant and CoStar COMPS subscription contracts,
which generate the largest portion of our revenue, range from terms of one to three years. At the end of the term
of each agreement our clients may decide not to renew their agreements as a result of several factors, including
alternative  products, consolidation  in  the  real  estate  industry, or  economic  or  competitive  pressures.  If  clients
decide not to renew their agreements, then our revenues will be adversely affected.

Competition could render our services uncompetitive. The market for information systems and services in
general is highly competitive and rapidly changing. The barriers to entry for web-based services and businesses
are low, making it possible for the number of competitors to proliferate rapidly. Many of our existing competi-
tors, or  a  number  of  potential  new  competitors, may  have  longer  operating  histories  in  the  Internet  market,
greater  name  recognition, larger  customer  bases, lower  prices, easier  access  to  data, 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. Increased competition could result in
lower revenues and higher expenses, which would reduce our profitability.

If our data is not accurate, comprehensive or reliable, our business could be harmed. Our success depends
on our clients’ confidence in the comprehensiveness, accuracy and reliability of the data we provide. The task of
establishing and maintaining accurate and reliable data is challenging. If our data is not current, accurate, com-
prehensive or reliable, we could experience reduced demand for our services or legal claims by our customers,
which could result in lower revenues and higher expenses.

17

Cyclical downturns and consolidation in the commercial real estate industry could have an adverse effect on
our business. Our business may be affected by conditions in the commercial real estate industry, including condi-
tions affecting businesses that supply or invest in that industry. A decrease in the level of commercial real estate
activities could adversely affect demand for our services. The traditional economic downturns in the commercial
real estate industry could also 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.

General economic conditions could have an adverse effect on our business. Our business, and the commer-
cial  real  estate  industry, is  particularly  affected  by  negative  trends  in  the  general  economy. The  success  of  our
business depends on a number of factors relating to general global, national, regional and local economic condi-
tions, including inflation, interest rates, perceived and actual economic conditions, taxation policies, availability
of credit, employment levels, and wage and salary levels. A negative trend in any of these general economic con-
ditions  could  adversely  affect  our  business.  For  example, a  recent  downturn  in  telecom  related  businesses  has
forced many of our telecom company clients to discontinue or curtail their operations, which has resulted in an
increased number of cancellations of our services. If other clients choose to cancel our services as a result of eco-
nomic conditions, our financial position could be adversely affected.

If we are unable to hire, retain and continue to develop our sales force, it could have a material adverse effect
on our business. In order to support revenue growth, we need to continue to develop, train and retain our sales
force. Our ability to build and develop a strong 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 sales
personnel; our ability to effectively train our sales force; the ability of our sales force to sell an increased number
of products; our ability to manage a multi-location sales organization; and the length of time it takes new sales
personnel  to  become  productive.  If  we  are  unable  to  hire, develop  or  retain  the  members  of  our  sales  force, it
could have a material adverse effect on our revenues.

We may not be able to successfully introduce new products. Our future business and financial success will
depend  on  our  ability  to  continue  to  introduce  new  products  into  the  marketplace.  Developing  new  products
imposes heavy burdens on our systems development department, product managers, management and researchers.
In addition, successfully launching and selling a new product, such as CoStar Connect or CoStar Exchange, puts
pressure on our sales and marketing resources. If we are unable to develop new products, then our customers may
choose a competitive service over ours and our business may be adversely affected. In addition, if we incur sig-
nificant costs in developing new products, 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 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 products and services, and introducing and integrating new services and products to capitalize on
the technological advances in the Internet. 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, stor-
age, 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 indus-
tries. Our business increasingly depends on our ability to anticipate and adapt to all of these changes, as well as
our customers’ ability to adapt to the use of our existing and future services and products on the Internet. We could
incur substantial costs if we need to modify our services or infrastructure in order to adapt to these changes, and
our customers’ failure to accept these changes could have a material adverse effect on our revenues. If we incurred
significant costs without adequate results or we are unable to adapt to rapid technological changes, it could have a
material adverse effect on our business.

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 our Web site, the Internet or the Web may impede the devel-
opment of our business for a number of reasons. As the number of Internet users or their use of Internet resources

18

continues to grow, and as companies deliver increasingly larger amounts of data over the Internet, the Internet’s
infrastructure must also grow. Growth in Internet usage that is not matched by comparable growth of the infra-
structure supporting the Internet could result in slower response time, cause outright failure of the Internet, or oth-
erwise adversely affect usage. In addition, if we experience technical problems in distributing our products over
the Web, including without limitation interruption or failure of services provided by our local exchange carriers or
internet service providers, we could experience reduced demand for our products.

Temporary or permanent outages of our computers, 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 business. If we
experience a failure that results in us not being able to deliver our products to clients, or to update our products,
we could experience reduced demand for our products.

We  may  be  subject  to  legal  liability  for  displaying  or  distributing  information. Because  the  content  in  our
database is distributed to others, we may be subject to claims for defamation, negligence or copyright or trade-
mark infringement or claims based on other theories. These types of claims have been brought, sometimes suc-
cessfully, 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 supplied by third
parties. Even to the extent these claims do not result in liability to us, we could incur significant costs in investi-
gating 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 sub-
stantial resources and limit the attractiveness of our service to users.

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, patent, copyright and other laws, nondisclosure and noncompetition pro-
visions, license  agreements  and  other  contractual  provisions  and  technical  measures  to  protect  our  intellectual
property rights. However, current law may not provide for adequate protection of databases and the actual data. In
addition, legal  standards  relating  to  the  validity, enforceability  and  scope  of  protection  of  proprietary  rights  in
Internet-related businesses are uncertain and evolving, and we cannot assure you of the future viability or value of
any of our proprietary rights. Our business could be significantly harmed if we do not succeed in protecting our
content and our other 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 are involved, either as a
plaintiff or as a defendant, could cost us a significant amount of time and money. In addition, if any intellectual
property claims are adversely determined, this could result in a material adverse result on our financial position.

Litigation in which we become involved may adversely affect our business. We currently and from time to
time are involved in litigation incidental to the conduct of our business. We cannot assure you that we will have
insurance to cover our pending claims or our future claims. Any lawsuits in which we are involved could cost us
a significant amount of time and money. If any pending claims or future claims are adversely determined, they
could have a material adverse effect on our financial position or results of operations.

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 Florance, our officers and other key employees. 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. To retain and attract key personnel, we use various
measures, including employment agreements, a stock option plan, and incentive bonuses for key executive offi-
cers. 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 officers or employees.

Our business depends on our management team’s ability to execute our business plan. In 2000, we added
several key officers to our management team. Our business depends on the successful integration of these new
officers, and the ability of our assembled management team to successfully execute our business plan. The inabil-
ity of our management team to successfully integrate our new officers or execute our business plan could have an
adverse effect on our operations.

19

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 funds only on unattractive terms. If we require additional funds and are not able to obtain
such funds, it would have a material adverse effect on our operations.

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.

We may not be able to manage successfully our geographic expansion. Our future business and financial suc-
cess will depend on our ability to manage our geographic expansion. Our efforts to manage expanded growth must
occur while information technology is rapidly changing. These efforts impose additional burdens on our research,
systems development, sales and general managerial resources. If we are not able to manage our expanded growth
successfully, it would have a material adverse effect on our profitability.

If we are unable to provide our clients with training and technical support, our business could be harmed.
Since many of our clients are not sophisticated computer users, it is important that they find our products easy to
use. To meet these needs, we provide client training and have developed a client support network that seeks to
respond  to  client  inquiries  as  soon  as  possible.  If  we  do  not  maintain  adequate  training  and  support  levels, we
could experience reduced demand for our services.

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. 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
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 have risks associated with legislation in the real estate industry. Real estate is a regulated industry in the
United States. These laws and related regulations, and any newly adopted regulations, may limit or restrict our
activities or could require us to expend significant resources to comply. As the real estate industry evolves in the
Internet environment, legislators, regulators and industry participants may advocate additional legislative or regu-
latory initiatives. Should existing laws or regulations be amended or new laws or regulations be adopted, we may
need to comply with additional legal requirements and incur resulting costs, or we may be precluded from certain
activities. In addition, if we are found to be in violation of these regulations, we may incur penalties and legal
costs or we may be precluded from certain activities.

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
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.

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, we expect that like most stocks, it will continue to fluctuate in the future. The
price could fluctuate 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 new services; general conditions in the commercial real estate industry; developments or disputes

20

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 shares 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 pre-
mium for their shares.

REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
CoStar Group, Inc.

We have audited the accompanying consolidated balance sheets of CoStar Group, Inc. as of December 31,
1999  and  2000, and  the  related  consolidated  statements  of  operations, stockholders’ equity  and  cash  flows  for
each of the three years in the period ended December 31, 2000. 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, 1999 and 2000, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended December 31, 2000, in conformity
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 holding company. 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 has
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 LeaseTrend, Inc.
(“LeaseTrend”) acquired on January 8, 1999, Jamison Research, Inc. (“Jamison”) acquired on January 22, 1999,
ARES  Development  Group, LLC  (“ARES”)  acquired  on  September  15, 1999, COMPS.COM, Inc.  (“Comps”)
acquired  on  February  10, 2000  and  First  Image  Technologies, Inc.  (“First  Image”)  acquired  and  merged  into
Comps on November 9, 2000. LeaseTrend and Jamison were merged into CoStar Realty on December 31, 1999
and ARES was merged into CoStar Realty on December 31, 2000.

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 finan-
cial 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. Deferred revenue results from advance cash receipts from the sales of licenses
and is recognized over the term of the licenses.

Significant Customers

No single customer accounted for more than 5% of our revenues as of December 31, 2000. The Company

operates solely within one business segment.

Comprehensive Income (Loss)

For the years ended December 31, 1998, 1999 and 2000, the Company’s net income (loss) reflects compre-

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

Advertising Costs

The  Company  expenses  advertising  costs  as  incurred. Advertising  expense  was  $904,600, $1,332,000  and

$4,028,000 for the years ended December 31, 1998, 1999 and 2000, 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  offering, the  partnership  became  part  of  the  Company  and  its  taxable  income  (loss)  flowed  through  to  the
Company. 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 two institutions. At December 31, 2000, cash of
$180,000 and $100,000 was held in accounts to support letters of credit securing lease obligations at the Company’s
Bethesda, Maryland headquarters and the on-line e-commerce portion of the Comps business, respectively.

Concentration of Credit Risk and Financial Instruments

The Company performs ongoing credit evaluations of its customers’ financial condition and generally does
not require that its customers’ obligations to the Company be secured. The Company maintains reserves for credit
losses, and such losses have been within management’s expectations. The risk of nonpayment of the Company’s
accounts receivable is mitigated by the large size and widespread nature of the Company’s 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.

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 products 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  $160,000, $219,000  and  $318,000  of  expense  related  to  the  capitalized  product
development costs for the years ended December 31, 1998, 1999 and 2000, respectively.

Goodwill, Intangibles and Other Assets

Goodwill and other intangibles represent the unamortized excess of the cost of acquiring companies over the
fair value of such companies’ net tangible assets at the dates of acquisition. Goodwill, acquired database technol-
ogy, and customer base, which are related to the Company’s acquisitions as described in Note 3, are being amor-
tized on a straight-line basis over periods ranging from two to ten years. The cost of photography is amortized 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 reflects the dilutive effects of outstanding stock and other dilutive common stock equivalents
if any. Diluted loss per share is equal to the basic loss per share as the effect on the calculation of basic loss per
share assuming the exercise of common stock equivalents is anti-dilutive.

New Accounting Pronouncements

In June 2000, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting
Standards  (“SFAS”)  No.  138, “Accounting  for  Certain  Derivative  Instruments  and  Certain  Hedging Activities,”
which  amends  SFAS  No.  133, “Accounting  for  Derivative  Instruments  and  Hedging Activities.” SFAS  No.  133

F-9

was  previously  amended  by  SFAS  No.  137, “Accounting  for  Derivative  Instruments  and  Hedging Activities—
Deferral of the Effective Date of FASB Statement 133,” which deferred the effective date of SFAS No. 133 to
fiscal  years  beginning  after  June  15, 2000.  The  Company  expects  to  adopt  SFAS  No.  138  and  SFAS  No.  133
effective January 1, 2001. SFAS No. 133 and SFAS No. 138 will require the Company to recognize all derivatives
on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income.
If  the  derivative  is  a  hedge, depending  on  the  nature  of  the  hedge, changes  in  the  fair  value  of  derivatives  will
either be offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earn-
ings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective
portion of a derivative’s change in fair value will be recognized immediately in earnings. The adoption of these
new standards is not expected to materially effect the Company’s financial position or results of operations.

In December, 1999, the Securities and Exchange Commission (“the Commission”) issued Staff Accounting
Bulletin (“SAB”) No. 101, “Revenue Recognition in Financial Statements.” SAB 101 summarizes certain of the
Commission’s  views  in  applying  generally  accepted  accounting  principles  to  revenue  recognition  in  financial
statements. In June, 2000, the Commission issued SAB 101B to defer the effective date of implementation of SAB
101 to the fourth quarter of 2000. The Company’s adoption of SAB 101 did not have an effect on its results of
operations and financial position.

3. Acquisitions

On  January  8, 1999, the  Company  acquired  all  of  the  outstanding  capital  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 outstanding capital 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 provided for $1,000,000 of additional consideration (in a combination of cash and stock) to
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. As a result, the Company adjusted good-
will by approximately $515,000. In October, 2000, the Company issued an additional 2,196 shares of its common
stock and paid an additional $437,500 in cash to the members of ARES for the achievement of the final operating
goal by the members of ARES. As a result, the Company adjusted goodwill by approximately $512,000.

On February 10, 2000, the Company acquired all of the outstanding capital stock of COMPS.COM, Inc., a
San Diego based provider of commercial real estate information, for $49,015,905 in cash and 2,259,034 shares of
the Company’s common stock. The acquisition has been accounted for using purchase accounting and has been
valued  at  approximately  $101,379,000  for  accounting  purposes.  The  purchase  price  was  allocated  primarily  to
cash, acquired database technology and other intangibles, which will be amortized over a period of 2 to 10 years.
In connection with the acquisition, $5,812,000 of the purchase price was allocated to purchased in-process devel-
opment, and expensed upon acquisition because the technological feasibility of products under development had
not  been  established  and  no  future  alternative  use  existed.  The  acquired  in-process  development  was  analyzed
through an independent third-party valuation using the expected cash flow approach.

On  November  9, 2000, CoStar  completed  the  acquisition  of  First  Image  Technologies, Inc.  The  primary
asset of First Image is the Metropolis software system, a single interface that combines commercial real estate
data from multiple information providers into a comprehensive resource. The Company acquired all of the out-
standing capital stock of First Image Technologies, Inc. for approximately $665,000 in cash and 9,424 shares of

F-10

the Company’s common stock. The transaction was accounted for as a purchase and the initial consideration was
valued for accounting purposes at approximately $950,000 including acquisition expenses. In addition, the acqui-
sition agreement provides for $950,000 of additional consideration (in a combination of cash and stock) to be paid
by the Company upon the achievement of certain operating goals by the sole stockholder of First Image.

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  years  ended
December 31, 1999 and 2000, assuming the acquisition of LeaseTrend, Jamison, ARES, Comps and First Image
had been consummated as of January 1 of each period, is summarized as follows:

5. 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 the prime interest rate plus 1%. In connection
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). During February, 2000, the partner exercised warrants for the purchase of 45,450
shares by a net exercise and received 35,294 shares.

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  1998, the  Company  incurred  fees  of  approxi-
mately  $82,912  related  to  such  consulting  services.  These  agreements  were  terminated  in  connection  with  the
Company’s initial public offering.

6. 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 the financial statement and tax basis of assets and liabilities using enacted rates expected to be
in effect during the year in which the differences reverse. Deferred taxes reflect the net tax effects of temporary
differences  between  the  carrying  amounts  of  assets  and  liabilities  for  financial  reporting  purposes  and  tax  pur-
poses.  Through  June  30, 1998, the  Company  operated  as  a  partnership  for  federal  income  tax  purposes.  The
Company paid no income taxes in 1998, 1999 or 2000.

A valuation allowance has been established against the related net deferred tax assets due to the uncertainty
of  realization.  The  Company’s  change  in  valuation  allowance  amounted  to  approximately  $5,277,000  and
$13,323,000 during the years ended December 31, 1999 and 2000. The increase in the valuation allowance relates
to current period operating losses and in 2000 was offset by the recognition of deferred tax assets associated with
net operating losses utilized as a result of acquisitions made during the period.

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, 2000, the Company had net operating loss carryforwards for federal income tax purposes of
approximately $62,984,000, which expire, if unused, from the year 2010 through the year 2020. The tax benefit of
approximately $9,700,000 of net operating losses related to stock options will be credited to equity when the ben-
efit is realized through utilization of the net operating loss carryforwards. Additionally, during 2000, the Company
made an acquisition which had net operating loss carryforwards of approximately $19,359,000, which expire, if
unused, through the year 2019. The use of these acquired net operating losses is subject to limitation imposed by
the Internal Revenue Code and is also restricted to the taxable income of the subsidiaries generating the losses.

F-12

During 1999 and 2000, the Company made acquisitions reported using the purchase method of accounting.
These acquisitions included identified intangible assets, which in accordance with SFAS 109, required deferred
taxes  and  related  goodwill  to  be  recorded. At  December  31, 1999  and  2000, the  amount  of  the  deferred  taxes
related  to  these  items  was  approximately  $6,988,000  and  $18,092,000, respectively.  The  deferred  taxes  will
reverse over the life of the identified intangible assets. Additionally, net operating losses from the acquired com-
pany and net operating losses from CoStar prior to the acquisition, totaling approximately $39,600,000, were val-
ued  in  connection  with  the  acquisition.  The  reversal  of  these  deferred  taxes  in  future  periods  may  result  in
additions to the valuation allowance and the recording of additional tax expense in accordance with the provisions
of SFAS 109, requiring evaluation regarding future realization.

7. Commitments

The Company leases office facilities and office equipment under various noncancelable operating leases. The
leases contain various renewal options. Rent expense for the years ended December 31, 1998, 1999 and 2000 was
approximately $1,031,000, $2,440,000 and $5,595,000, respectively. 

Future minimum lease payments as of December 31, 2000 are as follows:

8. Sales of Common Stock

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 the subordinated debt to a 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  $97,411,000, after  deducting  underwriting  discounts  and  commissions  and  offering
expenses of $1,024,000.

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 3,000,000 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.

The  Company  follows  the  disclosure  provisions  of  SFAS  No.  123. Accordingly, no  compensation  cost  has
been recognized for the Plan. Had compensation expense related to the Plan been determined based on the fair
value at the grant date for options granted consistent with the provisions of SFAS No. 123, Company’s pro forma
net  loss  and  net  loss  per  share  would  have  been  approximately  $3,912,000, $16,824,000  and  $57,597,000, and
$0.54, $1.43  and  $3.81  for  the  years  ended  December  31, 1998, 1999  and  2000, 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 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 weighted average
fair value of options granted during 2000 was $20.44 using the Black-Scholes option-pricing model with the fol-
lowing assumptions: dividend yield 0%, expected volatility of 87%, risk-free interest rate of 6.3% 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  1%  and  15%  of  employees’ salaries, limited  to  a
maximum annual amount as established by the Internal Revenue Service. The Company matched 25% in 1998, and
100% in 1999 and 2000 of employee contributions up to a maximum of 6% of total compensation. Amounts con-
tributed to the 401(k) by the Company to match employee contributions for the years ended December 31, 1998,
1999 and 2000 were approximately $39,000, $364,000 and $698,000, respectively.
