"Common  Stock"),  of Realty  Information  Group,  Inc. (the "Company")  offered
hereby (the "Offering"),  2,109,091 are being offered by the Company and 590,909
are being  offered by  stockholders  (the  "Jamison  Selling  Stockholders")  of
Jamison  Research,  Inc., a business which the Company will acquire  immediately
prior to this Offering  through the issuance of 909,091  shares of Common Stock.

    Prior to this Offering, there has been no public market for the Common Stock
of the  Company,  and there is no  assurance  that a market  will  develop or be
sustained  after the  Offering.  It is  currently  anticipated  that the initial
public  offering  price  will be  between  $10.00  and  $12.00  per  share.  See
"Underwriting"  for a discussion of the factors to be considered in  determining
the initial public  offering  price.  The Company has applied to have the Common

Company."

                                  THE COMPANY

   

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

    

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

   

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

                                        3

<PAGE>

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

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

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

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

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

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

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

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

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

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

   

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

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

    

                                       4

<PAGE>

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

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

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

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

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

     The  Company  was formed in  February  1998 by RIGINC and RIGLP to acquire,
directly or indirectly, all of the outstanding equity interests in RIGINC, RIGLP

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

   

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

    

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

                  TRANSACTIONS IN CONNECTION WITH THE OFFERING

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

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

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

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

    

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

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

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

   

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

                                  RISK FACTORS

   

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

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

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

    

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

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

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

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

                                        9

<PAGE>

   

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

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

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

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

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

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

                                       10

<PAGE>

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

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

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

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

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

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

                                       11

<PAGE>

   

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

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

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

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

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

                                       12

<PAGE>

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

   

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

<PAGE>

                                USE OF PROCEEDS

   

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

                                DIVIDEND POLICY

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

                                    DILUTION
   

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

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

    exchange  for the  Company's  shares at a rate of 3.113  shares  of  Company
    Common  Stock  for each  share of  RIGINC or unit of RIGLP as if it had been
    consummated on January 1, 1993.

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

(3) Reflects charges of approximately $1.1 million and $275,000 for 1997 and the

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

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

OVERVIEW

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

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

     Comparison of March 31, 1997 and March 31, 1998

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

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

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

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

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

     Comparison of 1997 and 1996

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

                                       20

<PAGE>

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

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

   

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

    

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

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

     Comparison of 1996 to 1995

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

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

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

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

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

SUPPLEMENTAL REVENUE AND CONTRIBUTION MARGIN ANALYSIS OF ESTABLISHED REGIONS

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

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

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

    region.

(2) Earnings before interest,  taxes,  depreciation and amortization  ("EBITDA")
    shown here excludes  allocation of the Company's general and  administrative
    expenses. Management believes that EBITDA is an indicator of how established
    regions are  performing.  However,  EBITDA  should not be  considered  as an
    alternative to net income or loss (as an indicator of operating performance)
    or to cash  flows  generated  from  operating  activities  (as a measure  of
    liquidity)  determined  in accordance  with  generally  accepted  accounting
    principles.

(3) EBITDA as a percentage of revenues.

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

     As a result of the Jamison  Acquisition,  the Company  will  allocate  $7.0
million of the Jamison purchase price to capitalized  product  development costs
and intangible  assets,  that will be amortized  using estimated lives of two to
fifteen years,  and $3.0 million to in process  research and  development  which
will be charged to operations immediately following the Jamison Acquisition. The
estimated   charges  for  amortization  of  the  Jamison   capitalized   product
development and intangible assets are  approximately  $1.5 million for the first
two years,  and are  expected to decline to  approximately  $500,000 or less per
year thereafter.  Approximately  $1.1 million of the amortization in each of the
first two years relates to capitalized  product  development and will be charged
to cost of sales,  reducing  gross margins  substantially.
   
     The Company will make  significant  investments to convert  Jamison's data,
upgrade Jamison's clients to the Company's products and complete the development
of certain acquired  technology into products which are  commercially  viable in
the  Company's  other  markets.  These  projects are expected to cost up to $1.0
million to complete, including the cost of programming, consulting, training and
research,  and are  expected  to be  completed  within  two years.  The  Company
anticipates  that during this period,  the positive  cash flow expected from the
Jamison  operation  will be  largely  offset  by the  costs  of this  conversion
process.  There can be no  assurance  that the  conversion  and  development  of
Jamison's data,  products and clients will be completed in the time planned,  or
that the cost of these projects will not be greater than estimated.

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

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

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

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

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

     Comparison of 1997 and 1996 of Jamison

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

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

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

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

LIQUIDITY AND CAPITAL RESOURCES

   

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

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

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

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

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

                                    BUSINESS

OVERVIEW

   

     The  Company  is a leading  provider  of  comprehensive,  building-specific
information  to the United States  commercial  real estate  industry and related
industries.  The Company has created a proprietary  Database,  through  internal
development   and  strategic   acquisitions,   that  the  Company   believes  is
significantly  more  comprehensive,  accurate  and  up-to-date  than  any  other
database of  information  detailing  office and  industrial  space in the United
States.  The Database  includes  hundreds of data fields  providing  substantive
information as well as digitized photographs and floor plan images on individual
commercial buildings in the Company's markets. The Combined Database tracks over
eight billion  square feet of office and  industrial  space in more than 150,000
buildings,  better than twice the  coverage of the  Combined  Company's  nearest
competitor.  The Combined Database also contains detailed information on 120,000
tenants and 13,000  buildings for sale (with an aggregate asking price in excess
of $15  billion).  In  addition,  the  Company  has  developed  a  portfolio  of
multimedia  software products with Internet  connectivity that allows clients to
access the Database and from which the Company  generates revenue in each of its
markets.
    

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

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

INDUSTRY BACKGROUND

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

                                       26
<PAGE>

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

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

COMPETITIVE ADVANTAGES

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

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

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

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

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

                                       27

<PAGE>

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

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

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

STRATEGY

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

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

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

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

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

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

                                       28

<PAGE>

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

THE DATABASE

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

   

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

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

DATA COLLECTION

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

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

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

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

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

                                       29

<PAGE>

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

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

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

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

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

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

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

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

                                       30

PRODUCTS AND SERVICES

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

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

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

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

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

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

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

                                       31

<PAGE>

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

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

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

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

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

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

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

                                       32

<PAGE>

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

CLIENTS

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

   

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

SALES AND MARKETING

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

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

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

                                       33
<PAGE>

   

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

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

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

COMPETITION

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

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

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

                                       34

<PAGE>

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

PROPRIETARY RIGHTS

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

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

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

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

EMPLOYEES

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

FACILITIES

   
     The Company's corporate offices occupy  approximately 21,000 square feet in
Bethesda,  Maryland,  under leases and  subleases  expiring  June 30,  2000.  In
addition to its corporate  offices,  the Combined Company leases office space in
the following cities: New York; Los Angeles; Elmhurst,  Illinois; San Francisco;
Boston;  Newport  Beach;  Philadelphia;  Atlanta;  and Dallas.  Aggregate  lease
payments  for the  Combined  Company for the year ended  December  31, 1997 were
approximately $895,000. 
    

LEGAL PROCEEDINGS

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

(1) Includes unit options of RIGLP which have been converted to stock options of
    the Company at a rate of 3.113 shares of Common Stock per RIGLP unit.

(2) Calculated  based on the  amount  by  which  the  fair  market  value of the

EMPLOYEE BENEFIT PLANS

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

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

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

                          JAMISON SELLING STOCKHOLDERS

     In connection  with the  Transactions,  the Company  agreed to register for
resale up to 65%  percent of the shares  received  by Henry D.  Jamison,  IV and
Leslie Lees Jamison  pursuant to the Jamison  Contribution  Agreement.  They are
selling as part of the Offering, respectively, 367,677 and 223,232 shares of the
Company's Common Stock. Those shares represent 5.4% and 3.3%,  respectively,  of
the   Company's   Common  Stock  prior  to  the  Offering  and  4.1%  and  2.5%,
respectively,  of the  Company's  Common Stock after the  Offering  (assuming no
exercise of the Underwriters' Over-Allotment Option).

                              CERTAIN TRANSACTIONS

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

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

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

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

                                       43

<PAGE>

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

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

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

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

                          DESCRIPTION OF CAPITAL STOCK

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

COMMON STOCK

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

                                       44

<PAGE>

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

PREFERRED STOCK

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

REGISTRATION RIGHTS

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

    

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS

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

                                       45

<PAGE>

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

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

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

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

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

TRANSFER AGENT AND REGISTRAR

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

                        SHARES ELIGIBLE FOR FUTURE SALE

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

                                       46

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

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

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

   

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

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

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

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

</TABLE>

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

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

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

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

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

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

<PAGE>

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

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

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

   

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

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

                                 LEGAL MATTERS

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

                       INTRODUCTION TO UNAUDITED PRO FORMA

                     CONDENSED COMBINED FINANCIAL STATEMENTS

     The following  unaudited pro forma condensed combined financial  statements
give effect to (i) the  contribution  to Realty  Information  Group,  Inc.  (the
"Company") by the holders of units of Realty  Information  Group, L.P. ("RIGLP")
and the  stockholders  of OLD RIG, Inc.  ("RIGINC") of all of the units of RIGLP
(other than units held by RIGINC) and the capital  stock of RIGINC in return for
certain shares of Common Stock of the Company,  (ii) the  acquisition of Jamison
Research,  Inc.  ("Jamison"),  and (iii) the Company's  planned  initial  public
offering of 2,700,000  shares of Common Stock.  The  acquisition of Jamison will
occur  simultaneously  with the closing of the Company's initial public offering
and will be accounted for using the purchase method of accounting.
   
     The unaudited pro forma  condensed  combined  balance sheet gives effect to
the  formation  of the  Company  and the  acquisition  of Jamison as if they had
occurred on March 31, 1998. The unaudited pro forma condensed combined statement
of  operations  gives  effect to the  transactions  as if they had  occurred  on
January 1, 1997.     

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

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

                     CONDENSED COMBINED FINANCIAL STATEMENTS

1. GENERAL

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

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

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

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

2. ACQUISITION OF JAMISON

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

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

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

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

3. PRO FORMA ADUSTMENTS

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

     Pro forma condensed combined statement of operations:

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

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

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

     Pro forma condensed combined balance sheet:

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

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

    

                                       F-6

<PAGE>
   
   Offering adjustment:

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

4. WEIGHTED AVERAGE SHARES OUTSTANDING

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

                             NOTES TO BALANCE SHEET

1. ORGANIZATION

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and  liabilities at the
date of the  financial  statements  and the  associated  amounts of revenues and
expenses  during the  reporting  period.  Actual  results  could differ from the
estimates.

     Unaudited Balance Sheet

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

3. PLANNED TRANSACTIONS

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

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain

                         REALTY INFORMATION GROUP, L.P.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

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

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

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

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

     Reclassifications

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

     Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and  liabilities at the
date of the  financial  statements  and the  associated  amounts of revenues and
expenses  during the  reporting  period.  Actual  results  could differ from the
estimates.

     Revenue Recognition

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

     Cash and Cash Equivalents

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     Property and Equipment

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

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

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

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

     Unit Based Compensation

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

     Advertising Costs

   

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     Concentration of Credit Risk

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

     Recent Pronouncements
   
     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial  Accounting  Standards No. 130 ("SFAS 130"),  "Comprehensive  Income",
which is required to be adopted for the year ended  December 31, 1998.  SFAS 130
requires that an enterprise (a) classify items of other comprehensive  income by
their nature in the financial statements and (b) display the accumulated balance
of other  comprehensive  income separately from retained earnings and additional
paid-in capital in the Statements of Stockholders'  Deficit.  The implementation
of SFAS 130, "Comprehensive Income",  information on the financial statements is
not  expected to be material.  For all periods  presented,  including  the three
months ended March 31,  1998,  RIGLP had no items of  comprehensive  income and,
accordingly, the Statement does not apply.
    
     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments
of an Enterprise and Related  Information",  which is required to be adopted for
the year ended  December  31,  1998.  SFAS 131 changes the way public  companies
report  segment  information  in annual  financial  statements and also requires
those  companies to report  selected  segment  information in interim  financial
reports to stockholders. The disclosure for segment information on the financial
statements is not expected to be material.
   
     In October 1997, the AICPA issued SOP 97-2,  Software Revenue  Recognition,
which  changes  the   requirements   for  revenue   recognition   effective  for
transactions  that the Company will enter into  beginning  January 1, 1998.  The
implementation  of SOP 97-2 is not  expected  to have a  material  effect on the
financial  statements of RIGLP.  As of January 1, 1998 the Company adopted AICPA
SOP 97-2,  Software  Revenue  Recognition,  which was effective for transactions
that RIGLP entered into in 1998.  Prior years were not  restated.  The effect of
adopting  SOP 97-2 was not material in the  financial  statements  of RIGLP.  In
March 1998,  AcSEC issued SOP 98-4 which defers for one year the  implementation
of certain  prevision  of SOP 97-2.  The  issuance  of SOP 98-4 had no effect on
RIGLP.
    
    Pro Forma Loss Per Share

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

3. ACQUISITIONS

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

5. LINE OF CREDIT

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

6. RELATED PARTY TRANSACTIONS
   
     During 1997,  the general  partner of RIGLP  obtained a  commitment  from a
partner for an additional $1,000,000 of subordinated,  unsecured credit, bearing
interest at a rate equal to that of the line of credit.  In connection  with the
commitment,  the individual  contributing  partner has received warrants for the
purchase of 15,000 shares of stock of the general partner,  exerciseable only in
the event of an initial  public  offering or an equity funding in excess of $5.0
million ("a  triggering  event").  The warrants  have a two year term beyond the
triggering event and provide for the purchase of an equivalent  number of shares
at a price of 10% less  than the price of the stock  sold in an  initial  public
offering or an equity  funding in excess of $5.0 million.  At December 31, 1997,
$650,000 of  borrowings  were  outstanding  under the  commitment  and have been
advanced to RIGLP. Interest paid in 1997 totaled $8,055.
    
     Commencing  in May 1995 RIGLP  agreed to pay an investor  $10,000 per month
and the Chairman of RIGLP $6,667 per month for consulting services. During 1995,
1996 and 1997,  RIGLP  incurred  fees of  approximately  $130,000,  $200,000 and
$200,000, respectively, related to such consulting services.

8. SALES OF PARTNERSHIP UNITS

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

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

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

9. EMPLOYEE BENEFIT PLANS

     Unit Option Plan

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

</TABLE>

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

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

outstanding at December 31, 1997:

     Employee 401(k) Plan

     Effective  January 1, 1997, RIGLP  established a 401(k) Plan (the "401(k)")
to provide retirement benefits for eligible  employees.  The 401(k) provides for
tax deferred contributions of between 1% and 15% of employees' salaries, limited

compensation.  Amounts  contributed  to the  401(k)  by RIGLP to match  employee
contributions were $27,808 in 1997.

10. MANAGEMENT PLANS
   
     Related  to a filing  of a  Registration  Statement  on Form S-1 by  Realty

                        REPORT OF INDEPENDENT AUDITORS

Board of Directors OLD RIG, Inc.

     We have audited the  accompanying  consolidated  balance sheets of OLD RIG,
Inc. as of December 31, 1996 and 1997, and the related  consolidated  statements
of operations,  stockholders'  deficit and cash flows for the three years in the
period  ended   December  31,  1997.   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  generally  accepted  auditing
standards.  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 supporting
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 statement 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 consolidated  financial position of OLD RIG, Inc.
at December 31, 1996 and 1997,  and the results of its  operations  and its cash
flows for each of the three years in the period  ended  December  31,  1997,  in
conformity with generally accepted accounting principles.

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

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

     Unaudited Interim Statements

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

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

     Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and  liabilities at the
date of the  financial  statements  and the  associated  amounts of revenues and
expenses  during the  reporting  period.  Actual  results  could differ from the
estimates.

     Revenue Recognition

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

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

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

     Capitalized Product Development Costs

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

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

     Intangible Assets
   
     The value  assigned to the customer base  acquired  through the purchase of
NMS and Chicago  Resource,  Inc.,  and goodwill,  resulting from the purchase of
Space  Datagraphics  Systems,  Inc., in December 1994, are being  amortized on a
straight-line basis over ten years.  RIGINC continuously  evaluates and adjusts,
if necessary, the net realizable value of these assets.
    
     Income Taxes
   
     RIGINC is a Subchapter S Corporation  for federal income tax purposes under
which income,  losses,  deductions  and credits are allocated to and reported by
the individual  stockholders of the corporation.  Accordingly,  no provision for
income tax has been recorded in the financial statements. Upon the effectiveness
of the Registration Statement on Form S-1 (see note 10), RIGINC will become part
of  Realty  Information  Group,  Inc.,  the  successor,  and  will be taxed as a
C-Corporation.  Had the  S-Corporation  operated as a C-Corporation for the year
ended  December  31,  1995,  1996 and 1997 and the three  months ended March 31,
1998,  there would be no income taxes recorded as a result of the losses for the
periods.  NMS is a  corporation  which  provides  for  income  taxes  under  the
provisions  of  Statement  of  Financial  Accounting  Standards  No.  109. As of
December 31, 1997, NMS had net loss carryforwards of approximately  $522,000.  A
valuation  allowance has been  established  against the related net deferred tax
asset in its entirety. 
    

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

     Advertising Costs

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

     Concentration of Credit Risk

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


     Earnings (loss) Per Share

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     Recent Pronouncements

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

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

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


3. ACQUISITIONS

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

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

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

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

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

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

8. COMMON STOCK AND SALES OF PARTNERSHIP UNITS

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

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

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

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

9. EMPLOYEE BENEFIT PLANS

     Unit Option Plan

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

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

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

                        REPORT OF INDEPENDENT AUDITORS

Board of Directors
Jamison Research, Inc.

     We have audited the accompanying  balance sheets of Jamison Research,  Inc.
as of December  31, 1996 and 1997,  and the related  statements  of  operations,
stockholders'  deficit and cash flows for the years then ended.  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  generally  accepted  auditing
standards.  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 supporting
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 statement 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 financial  position of Jamison Research,  Inc. at
December 31, 1996 and 1997, and the results of its operations and its cash flows
for the years then ended,  in  conformity  with  generally  accepted  accounting
principles.

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates

     The  preparation of the financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and  liabilities at the
date of the  financial  statements  and the  associated  amounts of revenues and
expenses  during the reporting  period.  Actual  results could differ from those
estimates.

     Revenue Recognition

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

     Cash and Cash Equivalents

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

     Property and Equipment

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

     Capitalized Product Development Costs

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

     Concentration of Credit Risk

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

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

     Earnings (loss) Per Share

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

     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial  Accounting  Standards No. 130 ("SFAS 130"),  "Comprehensive  Income",
which is required to be adopted for the year ended  December 31, 1998.  SFAS 130
requires that an enterprise (a) classify items of other comprehensive  income by
their nature in the financial statements and (b) display the accumulated balance
of other  comprehensive  income separately from retained earnings and additional
paid-in capital in the Statements of Stockholders'  Deficit.  The implementation
of SFAS 130, "Comprehensive Income", on the financial statements is not expected
to be  material.  For all periods  presented,  including  the three months ended
March 31, 1998, RIGLP had no items of comprehensive income and, accordingly, the
Statement does not apply.
   
     In June 1997, the Financial  Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments
of an Enterprise and Related  Information",  which is required to be adopted for
the year ended  December  31,  1998.  SFAS 131 changes the way public  companies
report  segment  information  in annual  financial  statements and also requires
those  companies to report  selected  segment  information in interim  financial
reports to stockholders.  The disclosure of segment information on the financial
statements is not expected to be material.

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

3. COMMITMENTS

     Operating Leases

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

   
  1998 ........................  $ 170,200
  1999 ........................    146,000
  2000 ........................    145,100
  2001 ........................    143,300
  2002 and thereafter .........         --
                                 ---------
                                 $ 604,600
                                 =========
    

     Employment Agreements

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

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

4. RELATED PARTY TRANSACTIONS

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

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

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

5. INCOME TAXES

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

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

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

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

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

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

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

     (a) EXHIBITS -- See Index to Exhibits.

     (b) Financial Statement Schedules are not required.

ITEM 17. UNDERTAKINGS

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

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

     The undersigned registrant hereby undertakes that:

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

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

                  THIS AGREEMENT is executed as of the 24th day of April,  1998,
and effective as of January 1, 1998 (the "Effective  Date"),  by and between OLD

"Company"),  a  Delaware  corporation  which is the  general  partner  of Realty
Information Group, L.P. ("RIGLP"), a Delaware pimited partnership, and ANDREW C.
FLORANCE ("Executive").

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

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

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

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

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

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

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

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


<PAGE>



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

                  4.  Compensation.

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

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

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

                                      - 2 -

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

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

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

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

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

                  7.  Termination.

                      (a) By  the   Company  Without  Cause.   The  Company  may
terminate Executive's employment at any time, without Cause (as defined herein),
upon sixty (60) days  written  notice to  Executive.  If the Company  terminates
Executive's employment without Cause,  Executive:  (x) shall receive through the

of  termination,  the  compensation  provided for under  paragraph  4(a) of this
Agreement;  (y) shall be entitled  to receive  the bonus he would have  received
under the Bonus  Program  (as in  effect  on the date of  termination)  as if he
continued  in the  position he held  immediately  prior to  termination  for the
balance of the calendar year in which such termination occurs; and (z) shall be,
if not

                                      - 3 -

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

                      (b) By the  Company  For Cause.  Notwithstanding  anything
herein  to  the  contrary,  the  Company  shall  have  the  right  to  terminate
Executive's  employment  under this  Agreement  for "Cause." For the purposes of
this Agreement,  the term "Cause" shall mean (i) a material failure by Executive
to perform his duties  hereunder  which shall persist uncured by Executive for a
sixty (60) day period after written  notice is given to Executive  which details
the duties  which the Company  alleges  Executive  has failed to  perform;  (ii)

felony;  or (iii) any other  willful  act or  omission  by  Executive,  which is
materially  injurious to the financial  condition or business  reputation of the
Company or its affiliates, including without limitation any violation during the
term of  Executive's  employment  of  Executive's  obligations  under  Section 8
hereof.  Executive will not receive Base Salary or Fringe  Benefits with respect
to any period after his termination for Cause.  Upon  termination of Executive's
employment with Cause,  (A) Executive shall forfeit (x) all right to participate
in the Bonus Program and (y) all unvested  stock  options,  and (B) the exercise
period  for all vested  options  shall be sixty  (60) days  after  cessation  of
employment.

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

of any of the following events:

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

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

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

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

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

                  8.  Confidentiality, Invention and Non-Compete Agreement.

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

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

                                      - 5 -


<PAGE>



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

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

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

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

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

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

                                      - 6 -


<PAGE>



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

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

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

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

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

                                      - 7 -


<PAGE>



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

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

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

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

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

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

                              2425 Wyoming Street, N.W.
                              Washington, D.C. 20008

                  and if to Executive, to:

                              Andrew C. Florance
                              4948 Western Avenue
                              Bethesda, Maryland  20816

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

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

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

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

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

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

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

                                      - 9 -


<PAGE>



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

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

                              EMPLOYMENT AGREEMENT
                              --------------------

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

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

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

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

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

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

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

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

                                      


<PAGE>



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

                  4.  Compensation.

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

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

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

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

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

                                      - 2 -


<PAGE>



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

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

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

                  7.  Termination without cause.

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

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

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

                                      - 3 -


<PAGE>



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

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

                  10. Confidentiality, Invention and Non-Compete Agreement.

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

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

                                      - 4 -


<PAGE>



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

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

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

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

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

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

                                      - 5 -


<PAGE>



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

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

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

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

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

                           Andrew C. Florance
                           Chief Executive Officer
                           Realty Information Group
                           7475 Wisconsin Avenue

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

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

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

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

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

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

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

                                      - 7 -


<PAGE>


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

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

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

                              EMPLOYMENT AGREEMENT
                              --------------------

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

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

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

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

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

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

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

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

                                      


<PAGE>



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

                  4.  Compensation.

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

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

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

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

                                      - 2 -


<PAGE>



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

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

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

                  7.  Termination without cause.

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

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

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

                                      - 3 -


<PAGE>



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

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

                  10. Confidentiality, Invention and Non-Compete Agreement.

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

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

                                      - 4 -


<PAGE>



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

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

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

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

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

                                      - 5 -


<PAGE>



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

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

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

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

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

                      (a)  If to the Company:

                           Andrew C. Florance
                           Chief Executive Officer
                           Realty Information Group
                           7475 Wisconsin Avenue
                           Sixth Floor

<PAGE>



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

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

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

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

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

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

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

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

Ricketts ("Executive").

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

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

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

                  WHEREAS,   Executive  and  OLD  RIG  acknowledge  that  it  is

(Delaware),  Inc., (i) OLD RIG and RIGLP will be consolidated with RIG, and (ii)
this Employment  Agreement will be automatically  assigned to and assumed by RIG
pursuant to Section 15 without further action by any party.

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

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

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

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

                  4.  Compensation.

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

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

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

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

                                      - 2 -


<PAGE>



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

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

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

                  7.  Termination without cause.

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

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

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

                                      - 3 -


<PAGE>



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

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

                  10. Confidentiality, Invention and Non-Compete Agreement.

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

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

                                      - 4 -


<PAGE>



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

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

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

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

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

                                      - 5 -


<PAGE>



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

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

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

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

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

                       (a)      If to the Company:
                                Andrew C. Florance

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

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

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

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

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

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

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

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

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

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

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

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

<PAGE>



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

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

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

                  7. TERMINATION WITHOUT CAUSE.

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

                    (b) BY THE  EXECUTIVE.  After the second  anniversary of the
Effective Date of this Agreement, the Executive may without cause terminate this
Agreement,  by giving one  hundred  twenty  (120)  days'  written  notice to the
Company.  In such event,  at the sole  discretion of the Company,  the Executive
shall continue to render all services and shall be paid
                                      -2-
<PAGE>


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

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

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

                  10.  CONFIDENTIALITY, INVENTION AND NON-COMPETE AGREEMENT.

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

                         (i)  engage,  as  an  officer,  director,  shareholder,
owner, partner, member, joint venturer, or in a managerial capacity,  whether as
an employee, independent
                                      -3-
<PAGE>

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

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

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

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

               (b) The  Executive  acknowledges  that  during  the course of his
employment,  he may  develop  and obtain  access to trade  secrets,  proprietary
software and other "confidential  business  information" of the Company, such as
its  software  systems,  sources  of data,  databases  and  other  competitively
sensitive  information  kept in  confidence  by the Company  such as selling and
pricing  information and  procedures,  research  methodologies,  customer lists,
business and marketing plans, and internal financial  statements.  The Executive
agrees  to not use or  disclose  any  trade  secrets,  proprietary  software  or
confidential  business  information  to which he is exposed or has access in the
course of his employment  with the Company,  even if elements of any of them may
belong to third parties, during his employment and for so long afterwards as the
Company  seeks to maintain  as  confidential  the  proprietary  software,  trade
secrets or confidential business information, whether or not the software, trade
secrets and confidential  business  information are in written or tangible form,
except as required and  authorized  during the  performance  of the  Executive's
duties for and with the Company.  The Executive agrees that, given the nature of
the  Company's  business  and  business  plans  twenty-four  (24)  months  is  a
reasonable period during which disclosure of proprietary software, trade secrets
or confidential  information  would be injurious to the Company;  and that there
will never come a time when
                                      -4-
<PAGE>

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

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

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

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

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

      11.  NOTICES.  All notices  required or  permitted to be given under  this
Agreement shall be given by certified  mail,  return receipt  requested,  to the
parties at the

                  15.  ARBITRATION.  Any and all disputes hereunder not resolved
amicably  shall be resolved  only through  arbitration  by a single member panel
