"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.

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.,  Grubb & Ellis,  Merrill Lynch &
Co., Julien J. Studley, Inc., Jones Lang Wootton USA, and LaSalle Partners, Inc.
Many of these national  companies have multi-year,  multi-market  contracts with
the Company.  These  multi-market  contracts  strengthen the Company's  position
within the industry and ease the  Company's  entry into new markets by providing
an initial client base. In many instances,  the Company's entry into new markets
has been facilitated by demand from these industry leaders.

    

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

                                       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
and Jamison.  RIGINC,  which was  incorporated  and  organized  initially in the
District of Columbia,  operated  the  Company's  business  until  November  1994
(RIGINC  was  reincorporated  under the laws of  Delaware  in 1996).  RIGINC was
formerly  known as "Realty  Information  Group,  Inc.";  in connection  with the

- ----------
(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").

    shares  per share of RIGINC  or unit of RIGLP and the  shares  issued to the
    Jamison  stockholders  in  connection  with the Jamison  Acquisition.  Stock
    options and warrants  outstanding  have been excluded  from the  calculation
    because their effect is anti-dilutive.

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

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

                             AVAILABLE INFORMATION

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

                                  RISK FACTORS

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

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

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

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

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

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

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

                                       9

<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:

                     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.

</TABLE>

     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.


<PAGE>

     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
of regions and growing client base.

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

SUPPLEMENTAL REVENUE AND CONTRIBUTION MARGIN ANALYSIS OF ESTABLISHED REGIONS

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

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

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

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

(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.

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

SALES AND MARKETING

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

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

     The  Company  has  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.

     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

                                       33

<PAGE>

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  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

                                       34

<PAGE>

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  years of service with Jamison.  Mr. Jamison will become an officer
    of the Company in connection with the Jamison Acquisition.

     Michael  R.  Klein is a  founder  and has  been  Chairman  of the  Board of
Directors of the Company Since 1987.  He has been,  since 1974, a partner of the
law firm Wilmer,  Cutler & Pickering,  based in Washington,  D.C., where he is a
member of its five person management committee.  Over the past five years he has
served as a member of the board of directors (and Audit  Committee  Chairman) of
both National Education Corporation and Steck-Vaughn  Publishing Corporation and
as a director (and member of the Executive Committee) of Perini Corporation.  In
1990 to 1991, on leave from his law firm, he served as the Chief  Administrative
Officer and Vice Chairman of the Board of Directors of Republic Waste Industries
(now known as Republic Industries), Inc.

     Andrew C.  Florance is a founder of the Company and has served as President
and as a Director since 1987 and as Chief Executive Officer since 1995. Prior to
founding the Company,  Mr.  Florance was President of its  predecessor  company,
Real Estate Infonet,  a real estate public records  publishing  operation,  from
1985 to 1987. Mr. Florance held primary  responsibility for developing the first
generation software products for Federal Filings, a 13-D tracking service, which
was later  acquired by Dow Jones.  Mr.  Florance was a co-founder of an industry
trade association  (REI-NEX) and served on its board from 1993-96.  Mr. Florance
also served on the focus group  responsible for developing the concepts  related

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

                              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.

                                  UNDERWRITING

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

     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.

                          NOTES TO UNAUDITED PRO FORMA
             CONDENSED COMBINED FINANCIAL STATEMENTS- (CONTINUED)

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

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

3. PRO FORMA ADUSTMENTS

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

     Pro forma condensed combined statement of operations:

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

   

       (b)  A charge of $50,000 for  financing  costs is  recorded to  recognize
            46,695 warrants issued in connection with the  subordinated  debt of
            the Company.  Such warrants are  exerciseable at 10% below the price
            of the stock in an initial public  offering.  The fair value of each
            warrant is  estimated  on the date of grant using the Minimum  Value
            option-pricing    model   with   the   following    weighted-average
            assumptions:  dividend  yield  of 0%;  risk-free  interest  rate  of
            approximately  6.0%;  and  expected  life of 1 year.  This charge is
            offset by the net reduction of $26,000 in interest  expense of RIGLP
            due to the planned  repayment of debt from offering  proceeds.  This
            results in a net charge of $24,000 for the year ended  December  31,
            1997.  The reduction in interest  expense for the three months ended
            March 31, 1998 is $43,550.

    

       (c) 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. In process research and development  totaling  $3,000,000
            will be charged to equity at the time of the acquisition.

    

                                      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.

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

     Pro Forma Loss Per Share

   
     Pro Forma loss per share information is presented as if the Partnership had
operated as a  C-Corporation  for all periods  presented.  In February 1997, the
Financial  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.

     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:

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

6. RELATED PARTY TRANSACTIONS

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

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

7. COMMITMENTS

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

8. SALES OF PARTNERSHIP UNITS

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

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

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

9. EMPLOYEE BENEFIT PLANS

     Unit Option Plan

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

     Unit option activity was as follows:

</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.

     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

matches  25%  of  employee  contributions  up  to  a  maximum  of  6%  of  total
compensation.  Amounts  contributed  to the  401(k)  by RIGLP to match  employee
contributions were $27,808 in 1997.

10. MANAGEMENT PLANS

     Related  to a filing  of a  Registration  Statement  on Form S-1 by  Realty

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

     Use of Estimates

     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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     Capitalized Product Development Costs

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

     Intangible Assets

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

     Income Taxes

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

     Unit Based Compensation

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

     Advertising Costs

     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

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

   
     Earnings Per Share

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

     Recent Pronouncements

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

     In 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 1988.  Prior years were not restated.  The effect of
adopting SOP 97-2 was not material in the  financial  statements  of RIGINC.  In
March 1998,  AcSEC issued SOP 98-4 which defers for one year the  implementation
of certain  provisions  of SOP 97-2.  The  issuance of SOP 98-4 had no effect on
RIGINC.

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

6. RELATED PARTY TRANSACTIONS

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

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

7. COMMITMENTS

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

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

     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 shares amounts and transactions  have
been restated to refelect the split 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.

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

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

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Use of Estimates

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

     Unaudited Interim Statements

     The  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.

     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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     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.

     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 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, Jamison had no item 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 Review 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:

     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.

</TABLE>

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

     The  foregoing,   except  for  the   Securities  and  Exchange   Commission
registration fee, the National  Association of Securities  Dealers,  Inc. filing

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

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

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

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     In the three years preceding the filing of this Registration Statement, the

the payment of the exercise price. Such loan is being forgiven over a three year

and certain of its  affiliates in exchange for $275,646.  These units and shares

in full payment of deferred compensation of $300,000 owed to Mr. Florance. These
units were  purchased for  investment  purposes.  The issuance of such units was
effected in reliance on the exemption  from  registration  under Section 4(2) of
the Securities Act.

     8.  Simultaneously  with  this  Offering,  the  Company  will  issue  up to
6,820,727  shares  of  Common  Stock to the  limited  partners  of RIGLP and the
stockholders  of RIGINC and Jamison.  The Company will receive as  consideration

Act. The remainder of the shares to be issued to the stockholders of Jamison are

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.

                           "Selling  Holder" means any Holder that has requested
                  inclusion  of  Registrable  Securities  held by such Holder in
                  either a Demand  Registration or a Registration by the Company
                  pursuant to Section 3 hereof.


                  2.       Demand Registration.

                  (a) Request for  Registration.  At any time after the first to
occur of (i) an Initial Public  Offering or (ii) December 3, 1998,  either Allen
LLC or  Founders  LLC  may  request  that  the  Company  be  converted  into a C
corporation  (if not already so converted) and effect a  Registration  under the
Securities Act of all or part of its  Registrable  Securities on Form S-1 or any
similar long-form  Registration (a "Long-Form  Demand  Registration") or on Form
S-3 or any similar short-form Registration (a "Short-Form Demand Registration"),
if available.  A request for Registration  pursuant to this Section 2 (a "Demand
Registration")  shall specify the approximate  number of Registrable  Securities
requested to be Registered  and the  anticipated  per share price range for such
offering.  If  Allen  LLC or  Founders  LLC,  as the  case  may be,  intends  to
distribute the Registrable  Securities by means of an underwriting,  it shall so
advise  the  Company  in  its  request.   In  the  event  such  Registration  is
underwritten,  the  right of  other  Selling  Holders  to  participate  shall be
conditioned on such Selling Holders,  participation in such  underwriting.  Upon
receipt of any such request,  the Company shall  promptly give written notice of
such proposed registration to all Holders. Such Holders shall have the right, by
giving  written  notice to the Company within twenty (20) days after the Company
provides  its notice,  to elect to have  included in such  Registration  such of
their  Registrable  Securities  as such  Holders  may  request in such notice of
election.  Thereupon,  the Company  shall,  as  expeditiously  as possible,  use
commercially reasonable efforts to convert the Company to a C corporation (if it
has not  already  done so) and to effect the  Registration,  of all  Registrable
Securities  that the Company has been requested to so register  provided that if
the  underwriter  (if any)  managing the offering  determines  that,  because of
marketing factors, all of the Registrable  Securities requested to be registered
by all Holders may not be  included in the  offering,  then all Holders who have
requested Registration shall participate in the offering pro rata based upon the
number of Registrable Securities that they have requested to be so registered.

                  (b)  Registration  Statement  Form.  Registrations  under this
Section 2 shall be on such  appropriate  Registration  form of the Commission as
shall be selected by the Company and available to it under the  Securities  Act.
The Company agrees to include in any such Registration Statement all information
which,  in the  opinion of counsel to the  Selling  Holders  and  counsel to the
Company, is required to be included therein under the Securities Act.

                  (c)  Limitations  on  Registration.  The Company  shall not be
required  to effect  more than two (2)  Demand  Registrations  pursuant  to this
Section  2 at the  request  of  Allen  LLC  and not  more  than  one (1)  Demand
Registration  pursuant to this  Section 2 at the request of  Founders  LLC.  The
Company shall not be required to effect any Demand  Registration within a period
of 90 days after the effective date of any other Registration  effected pursuant
to Section 2.


                                        4

<PAGE>



                  (d) Priority on Demand Registrations. The Company may, subject
to Section 2(g), elect to include in any Registration Statement made pursuant to
Section 2,  authorized  but  unissued  Common  Shares or Common  Shares  held as
treasury stock.

                  (e) Effective  Registration  Statement.  A Demand Registration
shall not be deemed to have been  effected (i) unless a  Registration  Statement
with  respect  thereto  has  become  effective,  (ii)  if  after  it has  become
effective, such Registration is interfered with by any stop order, injunction or
other order requirement of the Commission or other governmental  agency or court
for any reason not  attributable  to the Selling  Holders and has not thereafter
become  effective,  or (iii)  if the  conditions  to  closing  specified  in the
underwriting   agreement,   if  any,   entered  into  in  connection  with  such
Registration  are not satisfied or waived,  other than by reason of a failure on
the part of the Selling Holders.

                  (f) Suspension.  If the Board of Directors of the Company,  in
its good faith  judgment,  determines  that any  Registration  of Common  Shares
should not be made or continued  because it would materially  interfere with any
material financing,  acquisition,  corporation reorganization,  merger, or other
transaction  involving the Company or any of its subsidiaries (a "Valid Business
Reason"),  (i) the Company may postpone filing a Registration Statement relating
to a Demand  Registration until such Valid Business Reason no longer exists, but
in no event for more than 90 days, and (ii) in case a Registration Statement has
been filed relating to a Demand  Registration,  if the Valid Business Reason has
not  resulted  from  actions  taken by the  Company,  the Company may cause such
Registration  Statement to be withdrawn and its effectiveness  terminated or may
postpone amending or supplementing such Registration  Statement until such Valid
Business  Reason  no longer  exists,  but in no event for more than 90 days (the
"Postponement Period"); provided, however, that in no event shall the Company be
permitted to postpone or withdraw a Registration Statement within 120 days after
the expiration of Postponement Period.

                  (g)  Allocation.   If  any  Demand  Registration  involves  an
underwritten offering and the managing underwriter of such offering shall advise
the Company that, in its view, the number of securities requested to be included
in such Registration exceeds the largest number (the "Section 2(g) Number") that
can be  sold in an  orderly  manner  in  such  offering  within  a  price  range
acceptable  to  the  Selling   Holders,   the  Company  shall  include  in  such
Registration:

                       (i) first,  all Common Shares requested to be included in
such Registration by the Selling Holders; provided, however, that, if the number
of such Common Shares exceeds the Section 2(g) Number, the number of such Common
Shares (not to exceed the Section 2(g) Number) shall be allocated to the Selling
Holders;  provided,  further,  however,  that if the  number  of  Common  Shares
requested to be included by all Selling Holders exceeds the Section 2(g) Number,
then the number of such Common  Shares  included in such  Registration  shall be
allocated on a pro rata basis among all Selling  Holders  requesting that Common
Shares be included in such  registration,  based on the number of Common  Shares
then owned by each Selling Holder requesting inclusion in relating to the number
of Common Shares then owned by all Selling Holders requesting inclusion; and

                                        5

<PAGE>



                       (ii)  second,  to the  extent  that the  number of Common
Shares to be  included  by all  Selling  Holders is less than the  Section  2(g)
Number, securities that the Company proposes to register.


                  3.       Company Registration.

                  (a)  Inclusion in Company  Registration.  Whenever the Company
proposes to file a Registration Statement (other than pursuant to Section 2 or a
Registration  relating  solely to the sale of  securities to  participants  in a
Company stock plan, or on Form S-4 with respect to any merger,  consolidation or
acquisition)  at any time and from time to time (a "Company  Registration"),  it
will, prior to such filing,  give written notice to all Holders of its intention
to do so and,  upon the written  request;  of a Holder or folders  given  within
twenty (20) days after the Company  provides  such notice  (which  request shall
state the intended method of disposition of such Registration  Securities),  the
Company  shall use  commercially  reasonable  efforts  to cause all  Registrable
Securities  Act the  Company  has been  requested  by such  Holder or Holders to
register to be registered  under the Securities  Act to the extent  necessary to
permit their sale or other  disposition in accordance with the intended  methods
of  distribution  specified  in the request or such Holder or Holders;  provided
that the Company  shall have the right to postpone or withdraw any  registration
effected pursuant to this Section 3 without obligation to any Holder.

                  (b) Term. In connection with any offering under this Section 3
involving  an  underwriting,  the  Company  shall not be required to include any
Registrable  Securities in such offering  unless the holders  thereof accept the
terms  of  the   underwriting  as  agreed  upon  between  the  Company  and  the
underwriters  selected by it provided  that such terms must be  consistent  with
this  Agreement),  and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by the Company.

                  (c)  Allocation.  If  any  Company  Registration  involves  an
underwritten offering and the managing underwriter of such offering shall advise
the Company that, in its view, the number of securities requested to be included
in such Registration exceeds the largest number (the "Section 3(c) Number") that
can be  sold in an  orderly  manner  in  such  offering  within  a  price  range
acceptable to the Company, the Company shall include in such Registration:

                           (i)  first,   all  Common  Shares  that  the  Company
proposes to register for its own account (the "Company Securities"); and

                           (ii) second, to the extent that the number of Company
Securities  is less than the Section 3(c)  Number,  the  remaining  shares to be
included in such  registration  shall be allocated on a pro rata basis among all
Selling Holders  requesting that Common Shares be included in such registration,
based  on the  number  of  Common  Shares  then  owned  by each  Selling  Holder
requesting  inclusion  in relation to the number of Common  Shares then owned by
all Selling Holders requesting inclusion.

                                        6

<PAGE>



                  4.   Allocation   of  Expenses.   The  Company  will  pay  all
Registration  Expenses  of all  Registrations  under this  Agreement;  provided,
however,  that if a Registration  under Section 2 is withdrawn at the request of
the Requesting Holder  requesting such  Registration  (other than as a result of
information  concerning the business or financial  condition of the Company that
is made  known to the  Holders  after the date on which  such  Registration  was
requested)  and if the  requesting  Holder elects not to have such  Registration
counted as a registration requested under Section 2, the requesting Holder shall
pay the Registration  Expenses of such  registration pro rata in accordance with
the number of their Registrable Securities included in such Registration.

                  5.  Obligations of the Company.  Whenever  required under this
Agreement to effect the  Registration of any Registrable  Securities  under this
Agreement, the Company shall, as expeditiously as reasonably possible:

                  (a) file with the  Commission a  Registration  Statement  with
respect to such Registrable  Securities and use commercially  reasonable efforts
to cause that Registration Statement to become and remain effective;

                  (b) prepare and file with the  Commission  any  amendments and
supplements to the  Registration  Statement and the  prospectus  included in the
Registration  Statement as may be necessary to keep the  Registration  Statement
effective for up to six months, in the case of a Long- Form Demand Registration,
and one year in the case of a Short-Form Demand  Registration,  or, if occurring
sooner,  until the date on which the distribution of the Registrable  Securities
shall be completed;

                  (c) furnish to each Selling Holder such reasonable  numbers of
copies of the prospectus, including a preliminary prospectus, in conformity with
the  requirements of the Securities Act, and such other documents as the Selling
Holder may  reasonably  request in order to facilitate  the public sale or other
disposition of the Registrable Securities owned by the Selling Holder; provided,
that if the Company  has  delivered  preliminary  or final  prospectuses  to the
Selling  Holders and after  having done so the  prospectus  is amended to comply
with the  requirements  of the Securities Act, the Company shall promptly notify
the Selling  Holders and, if requested,  the Selling  Holders shall  immediately
cease making offers of Registrable Securities and return all prospectuses to the
Company.  The Company shall  promptly  provide the Selling  Holders with revised
prospectuses  and,  following receipt of the revised  prospectuses,  the Selling
Holders shall be free to resume making offers of the Registrable Securities;

                  (d) use commercially reasonable efforts to register or qualify
the  Registrable  Securities  covered by the  Registration  Statement  under the
securities  or Blue  Sky  laws of  such  states  as the  Selling  Holders  shall
reasonably  request,  and do any and all  other  acts  and  things  that  may be
necessary or desirable to enable the Selling  Holders to  consummate  the public
sale or other disposition in such states of the Registrable  Securities owned by
the Selling Holder;

                  (e) in the event of any underwritten  public  offering,  enter
into and perform its obligations under an underwriting  agreement,  in usual and
customary form, with the managing

                                        7

<PAGE>



underwriter of such offering.  Each Holder  participating  in such  underwriting
shall also enter into and perform its obligations under such agreement; and

                  (f) notify each Holder of  Registrable  Securities  covered by
such  Registration  Statement at any time when a prospectus  relating thereto is
required to be delivered  under the Securities Act of the happening of any event
as a result of which the prospectus included in such Registration  Statement, as
then in effect,  includes  an untrue  statement  of a material  fact or omits to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein  not  misleading  in the  light  of the  circumstances  then
existing.

                  6.       Certain Obligations of Holders.

                           (a)  It  shall  be  a  condition   precedent  to  the
obligations  of the Company to take any action under this Agreement with respect
to the  Registrable  Securities  of any Selling  Holder  that such Holder  shall
furnish to the  Company  such  information  regarding  itself,  the  Registrable
Securities held by it, and the Intended method of disposition of such securities
as shall be required to effect the  Registration  of such  Holder's  Registrable
Securities.

                           (b) Each Holder of Registrable  Securities covered by
a  Registration  Statement  agrees  that,  upon  receipt of any notice  from the
Company  under  Section 5.(f)  hereof,  such Holder will  forthwith  discontinue
disposition of Registrable  Securities  pursuant to such Registration  Statement
until such Holder's  receipt of copies of a supplemented  or amended  prospectus
covering such Registrable  Securities,  and, if so directed by the Company, such
Holder will deliver to the Company (at the Company's expense) all copies,  other
than permanent file copies then in such Holder's  possession,  of the prospectus
covering such Registrable  Securities current at the time of its receipt of such
notice.

                  7.  Indemnification  and  Contribution.  In the  event  of any
Registrar  on of any of the  Registrable  Securities  under the  Securities  Act
pursuant to this  agreement,  the Company will  indemnify  and hold harmless the
Selling  Holder  of  such  Registrable  Securities,  each  underwriter  of  such
Registrable Securities, and each other person, if any, who controls such Selling
Holder or  underwriter  within the meaning of the Securities Act or the Exchange
Act, against any losses, claims,  damages, or liabilities,  joint or several, to
which such Selling Holder, underwriter, or controlling person may become subject
under the Securities  Act, the Exchange Act, state  securities or Blue Sky laws,
or  otherwise,  insofar as such losses,  claims,  damages,  or  liabilities  (or
actions in respect  thereof) arise out of or are based upon any untrue statement
or alleged untrue  statement of any material fact contained in any  Registration
Statement under which such  Registrable  Securities  were  registered  under the
Securities Act, any preliminary prospectus, or final prospectus contained in the
Registration  Statement,  or any amendment or  supplement  to such  Registration
Statement, or arise out of or are based upon the omission or alleged omission to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein not misleading;  and the Company will reimburse such Selling
Holder,  underwriter,  and each  such  controlling  person  in  connection  with
investigation or defending any such loss, claim, damage,  liability,  or action;
provided, however, that the Company will not be liable in any such case to the

                                        8

<PAGE>



extent that any such loss, claim, damage, or liability arises out of or is based
upon any untrue  statement  or  omission  made in such  Registration  Statement,
preliminary  prospectus,   or  final  prospectus,   or  any  such  amendment  or
supplement, in reliance upon and in conformity with information furnished to the
Company,  in writing,  by or on behalf of such Selling Holder,  underwriter,  or
controlling person specifically for use in the preparation thereof.

                  In the  event of any  Registration  of any of the  Registrable
Securities  under the  Securities Act pursuant to this  Agreement,  each Selling
Holder of Registrable Securities,  severally and not jointly, will indemnify and
hold  harmless  the  Company,  each  of its  directors  and  officers  and  each
underwriters  (if any) and each person,  if any, who controls the Company or any
such  underwriter  within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities,  joint or several, to which
the Company, such directors and officers, underwriter, or controlling person may
become subject under the Securities Act,  Exchange Act, state securities or Blue
Sky laws, or otherwise,  insofar as such losses, claims, damages, or liabilities
(or  actions  in  respect  thereof)  arise out of or are based  upon any  untrue
statement  or  alleged  untrue  statement  of a  material  act  contained  n any
Registration  Statement under which such Registrable  Securities were registered
under  the  Securities  Act,  any  preliminary  prospectus  or final  prospectus
contained in the Registration  Statement,  or any amendment or supplement to the
Registration  Statement,  or arise  out of or are  based  upon any  omission  or
alleged  omission  to state a material  fact  required  to be stated  therein or
necessary to make the  statements  therein not  misleading,  if the statement or
omission was made in reliance upon and in conformity with  information  relating
to such  Selling  Holder  furnished in writing to the Company by or on behalf of
such Selling Holder  specifically  for use in connection with the preparation of
such Registration Statement,  prospectus,  amendment,  or supplement;  provided,
however,  that the obligations of each selling Holder hereunder shall be limited
to an  amount  equal to the  proceeds  to such  selling  Holder  of  Registrable
Securities sold in connection with such Registration.

                  Each party  entitled to  indemnification  under this Section 7
(the  "Indemnified  Party")  shall give notice to the party  required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom;  provided,  that counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval  shall not be  unreasonably
withheld); and, provided,  further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the  Indemnifying  Party of its
obligations  under this Section 7. The Indemnified Party may participate in such
defense at such party's expense; provided,  however, that the Indemnifying Party
shall  pay such  expense  if  representation  of such  Indemnified  Party by the
counsel retained by the Indemnifying  Party would be inappropriate due to actual
or potential  differing  interests  between the Indemnified  Party and any other
party represented by such counsel in such proceeding.  No Indemnifying Party, in
the defense of any such claim or  litigation,  shall  except with the consent of
each  Indemnified  Party,  consent  to entry of any  judgment  or enter into any
settlement that does not include as an unconditional  term thereof the giving by
the  claimant  or  plaintiff  to such  Indemnified  Party of a release  from all
liability  in respect of such claim or  litigations,  and no  Indemnified  Party
shall

                                        9

<PAGE>


consent to entry of any judgment or settle such claim or litigation  without the
prior written consent of the Indemnifying Party.

                  In order to provide  for just and  equitable  contribution  to
joint  liability  under the  Securities  Act in any case in which either (i) any
holder of Registrable Securities exercising rights under this Agreement,  or any
controlling  person  of any  such  holder,  makes  a claim  for  indemnification
pursuant to this Section 7 but it is  Judicially  determined  (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to  appeal  or the  denial  of the  last  right  of  appeal)  that  such
indemnification  may not be enforced in such case  notwithstanding the fact that
this Section 7 provides for  indemnification  in such case, or (ii) contribution
under the  Securities Act may be required on the part of any such Selling Holder
or any such controlling  person in circumstances  for which  indemnification  is
provided  under this  Section 7; then,  in each such case,  the Company and such
Selling Holder will  contribute to the aggregate  losses,  claims,  damages,  or
liabilities  to which they may be subject  (after  contribution  from others) in
such proportions so that such holder is responsible for the portion  represented
by the percentage that the public  offering price of its Registrable  Securities
offered by the Registration  Statement bears to the public offering price of all
securities  offered  by  such  Registration   Statement,   and  the  Company  is
responsible  for the remaining  portion;  provided,  however,  that, in any such
case,  (A) no such holder will be required to contribute any amount in excess of
the  proceeds to it of all  Registrable  Securities  sold by it pursuant to such
Registration  Statement,  and (B) no  person  or  entity  guilty  of  fraudulent
misrepresentation,  within the meaning of Section 11(f) of the  Securities  Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation.

                  8. Indemnification with Respect to Underwritten  Offering.  In
the event  that  Registrable  Securities  are sold  pursuant  to a  Registration
Statement  in an  underwritten  offering,  the  Company  agrees to enter into an
underwriting agreement containing customary  representations and warranties with
respect to the  business and  operations  of an issuer of the  securities  being
registered  and  customary  covenants  and  agreements  to be  performed by such
issuer,  including  without  limitation  customary  provisions  with  respect to
indemnification by the Company of the underwriters of such offering.

                  9. Reports Under Securities  Exchange Act of 1934. With a view
to making  available to the Holders the benefits of Rule 144  promulgated  under
the Securities  Act and any other rule or regulation of the Commission  that may
at any time  permit a Holder to sell  securities  of the  Company  to the public
without Registration, the Company agrees to:

                           (a) Make and keep public  information  available,  as
                  those terms are  understood  and defined in Rule 144 under the
                  Securities  Act, at all times  following the ninetieth  (90th)
                  day  after  the  effective  date  of  the  first  Registration
                  Statement  filed  by  the  Company  for  the  offering  of its
                  securities to the general public;


                                       10

<PAGE>



                           (b) file with the  Commission  in a timely manner all
                  reports and other documents  required of the Company under the
                  Securities Act and the Exchange Act; and

                           (c)  furnish to any  Holder,  so long as such  Holder
                  owns any Registrable Securities,  forthwith upon request (i) a
                  written statement by the Company that it has complied with the
                  reporting requirements of Rule 144 under the Securities Act at
                  any  time  following  the  ninetieth   (90th)  day  after  the
                  effective date of the first  Registration  Statement  tiled by
                  the Company),  the Securities Act and the Exchange Act (at any
                  time   after  it  has  become   subject   to  such   reporting
                  requirements),  (ii)  a copy  of the  most  recent  annual  or
                  quarterly  report of the  Company  and such other  reports and
                  documents  so filed  by the  Company,  and  (iii)  such  other
                  information  as may be  reasonably  requested  in availing any
                  Holder  of any  rule or  regulation  of the  Commission  which
                  permits   the   selling   of  any  such   securities   without
                  Registration or pursuant to such form.

                  10. Transfer of Registration  Rights. The Registration  rights
of any Holder under this Agreement may not be  transferred  except (i) as to any
Investor,  to any  Affiliate  of such  Investor,  or (ii) to any person who is a
Permitted  Transferee  (as  such  term is  defined  in the  Limited  Partnership
Agreement  of the  Company)  of that  number  of Common  Shares  (or a number of
Limited  Partnership  Interests  exchangeable  for that number of Common Shares)
representing  not less than one percent (1%) of the  aggregate  common equity of
the Company outstanding (on a fully-diluted basis) at the time of such transfer;
provided,  however,  that the Company is given written notice from such Investor
at the time of such transfer  stating the name and address of the transferee and
identifying the securities with respect to which the rights  hereunder are being
transferred.  As a condition  to the  effectiveness  of any  transfer  permitted
hereunder  (i) the  transferee  shall  agree,  in writing,  upon  request of the
Company,  to be bound by the provisions of this Agreement,  and (ii) the Company
shall be given written  notice at the time of or within a reasonable  time after
said transfer,  stating the name and address of said  transferee or assignee and
identifying  the securities with respect to which such  Registration  rights are
being assigned.

                  11.   Allocation   of  Rights   to  Member  of  an   Investor.
Notwithstanding  anything to the contrary herein, it is understood and agreed by
the parties that the members of Allen r LC and Founders  LLC are  currently  the
ultimate  beneficial  owners of the Limited  Partnership  Interests held by each
such Investor and the rights contained  herein. At the direction of any Investor
upon any  Incorporation  Transaction,  the Company shall issue the Common Shares
issuable in  exchange  for the Limited  Partnership  Interests  directly to such
members of the Investor in such amounts as the Investor shall specify in lieu of
issuing  such Common  Shares to the  Investor.  Thereafter,  for all intents and
purposes  hereunder,  such members  shall be deemed  Holders as provided  herein
without  further  action and shall have the rights and  obligations  as provided
herein.

                  12.  "Stand-Off"  Agreement.  Each Holder, if requested by the
Company and an underwriter  of Common Stock or other  securities of the Company,
shall agree not to sell or

                                       11

<PAGE>



otherwise transfer or dispose of any Registrable  Securities or other securities
of the Company held by such Holder for a specified period of time (not to exceed
120 days)  following the effective date of a Registration  Statement;  provided,
that:

                  (a)  such  agreement  shall  only  apply  to  the  first  such
Registration  Statement  covering  Common Stock of the Company to be sold on its
behalf to the public in an underwritten offering; and

                  (b) all other holders of similar  securities  holding not less
than the number of such  securities  held by such  Holder  (including  shares of
Common  Shares  issuable in exchange for the Limited  Partnership  Interests and
issuable upon the conversion of convertible securities,  or upon the exercise of
options, warrants or rights) and all officers and directors of the Company enter
into similar agreements.

                  13.  Amendments  to  Founders  Purchase   Agreement  and  LBPC
Purchase  Agreement.  The  Founders  Purchase  Agreement  is hereby  amended  by
deleting in its  entirety  Article  VIII thereof  which  Article  shall be of no
further  force or  effect.  The LBPC  Purchase  Agreement  is hereby  amended by
deleting in its entirety Article VI thereof which Article shall be of no further
force or effect.

                  14.      Miscellaneous.

                  (a) No Inconsistent Agreements. The Company will not hereafter
enter into any agreement  with respect to its securities  which is  inconsistent
with or violates the rights granted to the Holders in this Agreement.

                  (b) Adjustments Affecting Registrable Securities.  The Company
will not take any  action,  or permit any change to occur,  with  respect to its
securities  that would  adversely  affect the  ability of the Holders to include
such  Registrable  Securities  in a  Registration  undertaken  pursuant  to this
Agreement or which would adversely affect the  marketability of such Registrable
Securities in any such Registration (including, without limitation,  effecting a
stock split or a combination of shares).

                  (c) Specific Performance;  Other Rights. The parties recognize
that various of the rights of the Investors under this Agreement are unique and,
accordingly,  the Investors  shall, in addition to such other remedies as may be
available  to any of them at law or in equity,  have the right to enforce  their
rights  hereunder by actions for injunctive  relief and specific  performance to
the extent  permitted  by law. The Company  hereby  waives any  requirement  for
security  or the  posting  of any  bond in  connection  with  any  temporary  or
permanent award of injunctive, mandatory or other equitable relief.

                  (d)  Successors  and Assigns.  Except as  otherwise  set forth
herein, all covenants, agreements and representations made herein shall bind and
inure to the benefit of each party hereto,  and their respective  successors and
assigns.

shall be any action taken,  or any statute,  rule  regulation or order  enacted,

Agreement shall not be amended or modified  except by a written  instrument duly

counterparts  and any party  hereto may  execute any such  counterpart,  each of

     8.8 GOVERNING LAW.

         (a) This Agreement shall be governed by and construed,  interpreted and
enforced in accordance with the laws of Delaware.

         (b) Any disputes  arising out of, in connection with or with respect to
this Agreement, the subject matter hereof, the performance or non-performance of
any  obligation  hereunder,  or  any  of the  transactions  contemplated  hereby
("Disputes")  that seek specific  performance  of any  obligations  hereunder or
injunctive   relief  shall  be  adjudicated  in  a  court  of  competent   civil
jurisdiction  sitting in  Wilmington,  Delaware,  and nowhere else.  Each of the
parties hereto hereby irrevocably  submits to the jurisdiction of such court for
the purposes of any suit,  civil action or other  proceeding  arising out of, in
connection  with or with respect to this  Agreement,  the subject matter hereof,
the performance or  non-performance of any obligation  hereunder,  or any of the
transactions  contemplated hereby  (collectively,  "Suit").  Each of the parties
hereto hereby waives and agrees not to assert by way of motion,  as a defense or
otherwise in any such Suit, any claim that it is not subject to the jurisdiction
of the above courts, that such Suit is brought in an inconvenient forum, or that
the venue of such Suit is improper.

         (c) Except as  provided  in Section  10.10(b),  all  Disputes  shall be
resolved  by  binding  arbitration  administered  by  the  American  Arbitration
Association  ("AAA") in Washington,  D.C. and,  except as expressly  provided in
this Agreement,  shall be conducted in accordance with the Expedited  Procedures
under the Commercial  Arbitration Rules of the AAA, as such rules may be amended
from time to time (the "Rules").

              (i) The hearing locale shall be Washington, D.C. A single, neutral
arbitrator (the "Arbitrator")  shall be appointed by the AAA, within thirty (30)
days after an Arbitrated Dispute is submitted for arbitration under this Section
10.10(c),  to  preside  over  the  arbitration  and  resolve  the  Dispute.  The
Arbitrator  shall be  selected  from the AAA's  Commercial  Panel,  and shall be
qualified to practice law in at least one jurisdiction in the United States and

                                     - 13 -

<PAGE>



have expertise in the interpretation of commercial contracts.  The parties shall
have ten (10) days to object in writing to the  appointment  of the  Arbitrator,
the sole basis for such objection being an actual conflict of interest. The AAA,
in its sole discretion, shall determine within ten (10) days the validity of any
objection to the  appointment of the Arbitrator  based on an actual  conflict of
interest.

              (ii) The Arbitrator's  decision (the "Decision") shall be binding,
and the  prevailing  party may  enforce the  Decision in any court of  competent
jurisdiction.

              (iii) The parties  shall use their best efforts to cooperate  with
each other in causing the arbitration to be held in as efficient and expeditious
a manner as practicable,  including but not limited to, providing such documents
and making  available such of their personnel as the Arbitrator may request,  so
that the Decision may be reached timely.  The Arbitrator shall take into account
the parties'  stated goal of expedited  proceedings  in  determining  whether to
authorize  discovery  and, if so, the scope of  permissible  discovery and other
hearing and pre-hearing procedures.

              (iv) The authority of the Arbitrator  shall be limited to deciding
liability for, and the proper amount of, a Claim,  and the Arbitrator shall have
no authority to award punitive  damages.  The Arbitrator  shall have such powers
and establish such  procedures as are provided for in the Rules, so long as such
powers and procedures are consistent  with this Section 8.8(c) and are necessary
to resolve the Dispute within the time periods specified in this Agreement.  The
Arbitrator  shall render a Decision within sixty (60) days after being appointed
to serve as  Arbitrator,  unless the parties  otherwise  agree in writing or the
Arbitrator  makes a finding  that a party has carried the burden of showing good
cause for a longer period.

     8.9  SEVERABILITY.  If any provision of this  Agreement or the  application
thereof to any person or  circumstances  is held invalid or unenforceable in any
jurisdiction,  the remainder  hereof,  and the  application of such provision to
such person or  circumstances in any other  jurisdiction,  shall not be affected
thereby, and to this end the provisions of this Agreement shall be severable.

     8.10  ABSENCE OF THIRD  PARTY  BENEFICIARY  RIGHTS.  No  provision  of this
Agreement is intended,  nor will any provision be interpreted,  to provide or to
create any third party beneficiary rights or any other rights of any kind in any
client,  customer,  affiliate,  shareholder,  employee  or  partner of any party
hereto or any other person or entity.

     8.11 FURTHER  REPRESENTATIONS.  Each party  further  represents  that it is
being  independently  advised  as to the tax  consequences  of the  transactions
contemplated  by this  Agreement  and is not  relying on any  representation  or
statements made by the other party as to such tax consequences.

                       AGREEMENT AND PLAN OF CONTRIBUTION


         THIS AGREEMENT AND PLAN OF CONTRIBUTION  (the  "Agreement") is made and
entered into this 17th day of February,  1998,  by and among Realty  Information
Group (Delaware),  Inc., a Delaware corporation  ("Parent"),  Realty Information
Group, Inc. a Delaware corporation ("RIGINC"), Realty Information Group, L.P., a
Delaware limited partnership  ("RIGLP" and, together with Parent and RIGINC, the
"RIG  Parties")  and  Jamison  Research,   Inc.,  a  Georgia   corporation  (the
"Company"),  Henry D. Jamison,  IV and Leslie Lees Jamison (each a "Stockholder"
and  collectively,  the  "Stockholders"  and,  together  with the  Company,  the
"Jamison Parties").

                                   BACKGROUND

         A. Parent was incorporated on February 2, 1998 (the "Formation")  under
the  laws  of the  State  of  Delaware  for the  purpose  of  acquiring  certain
commercial real estate information businesses; and

         B. Parent intends to undertake an initial public offering of its common
stock (the "IPO") in March or April 1998 and in connection  therewith intends to
file a  Registration  Statement  on Form S-1 with the  Securities  and  Exchange
Commission promptly following the execution of this Agreement; and

         C. The  shareholders  of RIGINC  intend to  contribute  their shares of
capital  stock of RIGINC to Parent in exchange for Parent  shares in  connection
with the IPO (the "RIGINC Contribution");

         D. The limited partners of RIGLP intend to contribute their partnership
units of RIGLP to Parent in exchange for Parent  shares in  connection  with the
IPO (the "RIGLP  Contribution" and,  collectively with the RIGINC  Contribution,
the "RIG Contributions");

         E. The Stockholders are the owners of all of the issued and outstanding
shares (the "Shares") of the capital stock of the Company;

         F. The Stockholders,  the Company,  and Parent deem it advisable and in
their  respective best interests that the  Stockholders  contribute all of their
shares of capital  stock of the Company to Parent in exchange for Parent  shares
as set forth herein (the "Jamison Contribution");

         G. The  Formation,  the IPO,  the RIG  Contributions,  and the  Jamison
Contribution are being undertaken pursuant to an integrated transaction intended
to qualify  under  Section 351 of the Internal  Revenue Code of 1986, as amended
(the "Transaction"); and

         H. Prior to, in connection with or following the Transaction, the board
of  directors of RIGINC  intend to rename  RIGINC  formally as "RIG,  Inc." and,
immediately thereafter, the board of directors of Parent intend to rename Parent
formally as "Realty Information Group, Inc.";

         NOW,   THEREFORE,   in   consideration  of  the  premises  and  of  the
representations,  warranties,  covenants and agreements  herein  contained,  the
parties hereto, intending to be legally bound, agree as follows:


                                   ARTICLE I.

                              PLAN OF CONTRIBUTION

         1.1 THE  CONTRIBUTION.  Upon the terms and  subject  to the  conditions
hereof,  at the Closing  (defined below),  the  Stockholders  will contribute to
Parent all of the Shares free and clear of all Liens (defined below) in exchange
for the  Consideration  specified  in  Section  1.2.  For the  purposes  of this
Agreement, "Lien" means any mortgage, security interest, pledge,  hypothecation,
assignment,  deposit  arrangement,  encumbrance,  lien (statutory or otherwise),
charge,  preference,  priority or other  security  agreement,  option,  warrant,
attachment, right of first refusal,  preemptive,  conversion, put, call or other
claim or right,  restriction  on transfer  (other than  restrictions  imposed by
federal and state securities  laws), or preferential  arrangement of any kind or
nature  whatsoever  (including  any  conditional  sale or other title  retention
agreement,  any financing lease involving substantially the same economic effect
as any of the  foregoing  and the filing of any  financing  statement  under the
Uniform Commercial Code or comparable law of any jurisdiction).

         1.2      CONSIDERATION.

                  (a) For purposes of this Agreement,  the "Consideration" shall
be Ten Million Dollars  ($10,000,000.00),  as adjusted  pursuant to Section 1.3.
The Consideration  shall be paid in shares of common stock of Parent,  par value
$0.01 (the "Parent Common  Stock"),  valued at the Share Price.  The Share Price
shall  be  either  (i)  the  price  at  which  the  underwriters  named  in  the
registration  statement  on Form S-1  covering  the  offer and sale of shares of
Parent  Common  Stock (the  "Registration  Statement")  in  connection  with the
Transaction and the IPO have agreed to purchase such shares,  or (ii) if no such
IPO is accomplished  by May 15, 1998,  such other price (or alternative  pricing
methodology) as the Stockholders' Representative (as defined in Section 1.5) and
the Parent may have  agreed to on or prior to May 25,  1998.  The Parent  Common
Stock  constituting  the  Consideration  shall be validly  issued,  fully  paid,
non-assessable  and, as of the Closing,  free and clear of all Liens (other than
liens  specifically  contemplated  herein).  Parent  Common  Stock  constituting
sixty-five  percent (65%) of the  Consideration  will be registered by Parent as
part  of the IPO for  immediate  resale  by the  Stockholders  (the  "Registered
Shares"),  twenty-five  percent  (25%)  of the  Consideration,  which  shall  be
Consideration  other than the Registered  Shares,  shall be restricted from sale
pursuant to Section 5.9 (the  "Restricted  Shares") and ten percent (10%) of the
Consideration,  which shall be Consideration  other than the Registered  Shares,
shall be pledged pursuant to Section 1.4 (the "Pledged Shares").

                  (b) The  Consideration  has been calculated based upon several
factors,  including the Company having a Net Worth (defined below) as of Closing
(the "Actual Net Worth") no less


                                       2

<PAGE>



than the Net Worth of the Company reflected on the Audited Financials,  which is
$(49,038) (the "Net Worth Target"). For purposes of this Agreement,  "Net Worth"
shall mean the total  shareholders'  equity  (deficit) as shown on the Company's
balance sheet in conformity with GAAP (defined below).

         1.3  POST-CLOSING  ADJUSTMENT.  The  Consideration  shall be subject to
adjustment after the Closing Date as specified in this Section 1.3:

                  (a)  Within  one  hundred  twenty  (120)  days  following  the
Closing,  Parent  shall  cause  Ernst & Young  LLP  (the  "Parent's  Independent
Auditors")  to audit  the  Company's  books to  determine  the Net  Worth of the
Company as of the  Closing  and the  accuracy  of the  information  set forth in
Section 3.8 (the "Post-Closing  Audit").  The parties acknowledge and agree that
for purposes of  determining  the  financial  performance  of the  Company,  all
financial  calculations  shall be done, except with the prior written consent of
Parent,  as provided in Section 3.8. The Stockholders  shall cooperate and shall
use their reasonable  efforts to cause the officers and employees of the Company
to cooperate  with Parent and Parent's  Independent  Auditors  after the Closing
Date in  furnishing  information,  documents,  evidence and other  assistance to
Parent's  Independent  Auditors to facilitate the completion of the Post-Closing
Audit  within  the  aforementioned  time  period.  In the  event  that  Parent's
Independent  Auditors  determine that the Net Worth of the Company as of Closing
was less than the Net Worth  Target,  Parent  shall  promptly  deliver a written
notice (the "Financial Adjustment Notice") to the Stockholders'  Representative,
as defined in Section 1.5, setting forth (i) the determination  made by Parent's
Independent  Auditors of the Net Worth of the Company,  (ii) the amount by which
the  Net  Worth  Target  exceeds  the  Net  Worth  determined  by  the  Parent's
Independent  Auditors (the "Proposed  Consideration  Adjustment")  and (iii) the
amount by which the  number of Shares  issued as  Consideration  would have been
reduced at Closing had the Consideration been reduced at Closing by the Proposed
Consideration Adjustment.

                  (b) The Stockholders'  Representative  shall have fifteen (15)
days from the receipt of the Financial Adjustment Notice to notify Parent if the
Stockholders  dispute  such  Financial  Adjustment  Notice.  If  Parent  has not
received  notice of such a dispute  within  such  15-day  period,  the  Proposed
Consideration  Adjustment shall be the Final Consideration Adjustment and Parent
shall be  entitled  to receive  from the  Stockholders  the Final  Consideration
Adjustment,  subject to the provisions of Section 8.7 hereof.  If, however,  the
Stockholders'  Representative  has delivered  notice of such a dispute to Parent
within such 15-day  period  (which  such  notice  shall state the  Stockholders'
calculation of Net Worth),  then Parent's  Independent  Auditors shall select an
independent  accounting  firm that has not represented any of the parties hereto
within the preceding two (2) years to review the Company's  books, the Financial
Adjustment  Notice  and the  notice of  dispute  (and  related  information)  to
determine the amount,  if any, of the Final  Consideration  Adjustment  (defined
below). Such independent accounting firm shall be confirmed by the Stockholders'
Representative  and Parent within three (3) days of its selection,  unless there
is an actual  conflict of interest.  The  independent  accounting  firm shall be
directed to consider  only those  agreements,  contracts,  commitments  or other
documents  (or  summaries  thereof)  that  were  either  (i)  delivered  or made
available to Parent's  Independent  Auditors in connection with the transactions
contemplated hereby, (ii) reviewed by


                                       3

<PAGE>



Parent's  Independent  Auditors during the course of the  Post-Closing  Audit or
(iii)  supplemental  information  supplied  by either  party to the  Independent
Accountant.  The independent accounting firm shall make its determination of the
Actual Net Worth and the amount by which the Net Worth Target exceeds the Actual
Net  Worth   determined  by  the   independent   accounting   firm  (the  "Final
Consideration  Adjustment"),  if any,  within thirty (30) days of its selection.
The determination of the independent  accounting firm shall be final and binding
on the parties hereto, and upon such determination,  Parent shall be entitled to
receive from the Stockholders the Final Consideration Adjustment, subject to the
provisions of Section 8.7 hereof.  The costs of the independent  accounting firm
shall be borne by the party  (either  the RIG Parties or the  Stockholders  as a
group) whose  determination  of the Net Worth as of the Closing was further from
the determination of the Actual Net Worth by the independent accounting firm, or
equally  by the  RIG  Parties  and  the  Stockholders  in  the  event  that  the
determination  by the  independent  accounting  firm is equidistant  between the
determination  of the  Net  Worth  by the  RIG  Parties  on one  hand,  and  the
Stockholders' calculation of Net Worth, on the other.

         1.4      PLEDGED ASSETS.

                  (a) As collateral security for the payment of any post-Closing
adjustment  to the Final  Consideration  Adjustment  under  Section  1.3, or any
indemnification  obligations of the  Stockholders  pursuant to Article VIII, the
Stockholders  shall,  and by execution  hereof do hereby,  transfer,  pledge and
assign to  Parent,  for the  benefit  of  Parent,  a  security  interest  in the
following assets (the "Pledged Assets"):

                           (i)  each   Stockholder's   Pledged  Shares  and  the
certificates  and  instruments,  if any,  representing  or evidencing  each such
Stockholder's Pledged Assets;

                           (ii)  all  securities  hereafter  delivered  to  such
Stockholder  with respect to or in substitution for such  Stockholder's  Pledged
Shares,  all  certificates  and  instruments  representing  or  evidencing  such
securities,  and all  non-cash  dividends  and other  property  (other than cash
dividends) at any time received,  receivable or otherwise distributed in respect
of or in  exchange  for any or all  thereof;  and in the event  any  Stockholder
receives any such property,  such Stockholder  shall hold such property in trust
for Parent and shall  immediately  deliver  such  property  to Parent to be held
hereunder as Pledged Assets; and

                           (iii) all  non-cash  proceeds of all of the foregoing
property  and  all  rights,  titles,   interests,   privileges  and  preferences
appertaining or incident to the foregoing property.

                  (b)  Each  certificate,  if any,  evidencing  a  Stockholder's
Pledged  Assets  issued  in his or her  name  in the  transactions  contemplated
hereby,  shall be  delivered  to Parent  directly by the  transfer  agent,  such
certificate  bearing  no  restrictive  or  cautionary  legend  other  than those
provided for by this  Agreement  or imprinted by the transfer  agent at Parent's
request.  Each Stockholder  shall, at the Closing,  deliver to Parent,  for each
such certificate, a stock power duly signed in blank by him or her.


                                       4

                  (c) The Stockholders shall be entitled to retain cash proceeds
from,  and exercise any voting powers  incident to, the Pledged  Assets that are
not applied to satisfy any Final  Consideration  Adjustment  pursuant to Section
1.3 or any  indemnification  obligation of the Stockholders  pursuant to Article
VIII.

                  (d) The Pledged Assets shall be available to satisfy any Final
Consideration  Adjustment  pursuant  to  Section  1.3  and  any  indemnification
obligations of the Stockholders  pursuant to Article VIII until the date that is
one (1) year after the Closing (the "Release Date").  On the Release Date or the
first  business day  thereafter,  Parent shall return or cause to be returned to
the  Stockholders  the Pledged  Assets,  less Pledged Assets having an aggregate
value equal to the amount of (i) any pending claim for a post-Closing adjustment
to the  Consideration  under  Section 1.3 or any  settled or  finally-determined
claim for a post-Closing  adjustment to the Consideration under Section 1.3, and
(ii) any pending claim for indemnification  made by any Parent Indemnified Party
(as defined in Article  VIII),  or any settled or  finally-determined  claim for
indemnification  made by any  Parent  Indemnified  Party (as  defined in Article
VIII), which such Pledged Assets shall be transferred to Parent. For purposes of
clause (i) of the  preceding  sentence,  the Parent Common Stock held as Pledged
Assets  shall be valued at the Share  Price;  and for purposes of clause (ii) of
the preceding sentence,  the Parent Common Stock held as Pledged Assets shall be

compliance with the requirements,  standards,  criteria and conditions set forth
in the Company Permits and other applicable orders, approvals,  variances, rules

transactions  contemplated by this Agreement will not result in a default under,
or a breach or  violation  of, or  adversely  affect  the  rights  and  benefits
afforded to the Company, by any Company Permit.

leases, or encumbrances of any nature thereon ("Encumbrances"). The Company does
not now own, nor has it ever owned,  Real Property.  The Real Property listed on
Schedule 3.15  includes all interests in real property  necessary to conduct the
business and operations of the Company.

                  (c)  All  oral  or  written   leases,   subleases,   licenses,

thereunder are free of all Liens. Except as set forth on Schedule 3.15(c),  none
of the  Leases  requires  the  consent  or  approval  of any  party  thereto  in

                                   ARTICLE V.

                                   COVENANTS

         5.1      TAX MATTERS.

         The following  provisions shall govern the allocation of responsibility
as between the Company, on the one hand, and the Stockholders, on the other, for
certain tax matters following the Closing Date:

                  ( a)  Stockholders  shall  prepare or cause to be prepared and
file or cause to be filed,  within the time and in the manner  provided  by law,
all Tax  Returns  of the  Company  (i) for all  periods  ending on or before the
Closing  Date  that are due after  the  Closing  Date and (ii) for all state and
Federal Tax Returns,  Tax Returns  covering the stub period from January 1, 1998
until the date of  Closing  Date.  Stockholders  shall pay to the  Company on or
before the due date of such Tax  Returns the amount of all Taxes shown as due on
such Tax Returns to the extent that such Taxes are not  reflected in the current
liability  accruals for Taxes  (excluding  reserves for deferred Taxes) shown on
the Company's  books and records as of the Closing  Date.  Such Returns shall be
prepared and filed in accordance with applicable law and in a manner  consistent
with past  practices  and shall be subject to review and approval by Parent.  To
the extent  reasonably  requested by the Stockholders or required by law, Parent
and the  Company  shall  participate  in the  filing  of any Tax  Returns  filed
pursuant to this paragraph.

                  (b) The Company shall prepare or cause to be prepared and file
or cause to be filed any Tax  Returns for Tax  periods  which  begin  before the
Closing  Date and end after the  Closing  Date  (except as  provided  in Section
5.1(a)(ii)).  The Stockholders shall pay to the Company within fifteen (15) days
after the date on which  Taxes are paid with  respect to such  periods an amount
equal to the


                                       31
<PAGE>


portion of such Taxes which relates to the portion of such taxable period ending
on the Closing  Date to the extent such Taxes are not  reflected  in the current
liability  accruals for Taxes  (excluding  reserves for deferred Taxes) shown on
the  Company's  books and records as of the Closing  Date.  For purposes of this
Section  5.1, in the case of any Taxes that are imposed on a periodic  basis and
are payable for a Taxable period that includes (but does not end on) the Closing
Date,  the  portion  of such Tax which  relates to the  portion of such  Taxable
period  ending on the Closing Date shall (x) in the case of any Taxes other than
Taxes based upon or related to income or receipts, be deemed to be the amount of
such Tax for the entire Taxable period multiplied by a fraction the numerator of
which is the number of days in the Taxable period ending on the Closing Date and
the denominator of which is the number of days in the entire Taxable period, and
(y) in the case of any Tax based upon or related to income or receipts be deemed
equal to the amount which would be payable if the relevant  Taxable period ended
on the Closing Date. Any credits relating to a Taxable period that begins before
and ends  after the  Closing  Date  shall be taken  into  account  as though the
relevant Taxable period ended on the Closing Date. All determinations  necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Company.

                  (c) Parent and the Company on one hand and Stockholders on the
other hand shall (A) cooperate  fully,  as reasonably  requested,  in connection
with the preparation and filing of Tax Returns  pursuant to this Section 5.1 and
any audit,  litigation  or other  proceeding  with  respect  to Taxes;  (B) make
available to the other, as reasonably  requested,  all  information,  records or
documents  with respect to Tax matters  pertinent to the Company for all periods
ending prior to or including  the Closing  Date;  and (C) preserve  information,
records or documents  relating  Tax matters  pertinent to the Company that is in
their  possession or under their control until the  expiration of any applicable
statute of limitations or extensions thereof.

                  (d)  The   Stockholders   shall   timely  pay  all   transfer,
documentary,  sales,  use, stamp,  registration and other Taxes and fees arising
from or relating to the  transactions  contemplated by this  Agreement,  and the
Stockholders  shall,  at their own expense,  file all  necessary Tax Returns and
other documentation with respect to all such transfer,  documentary, sales, use,
stamp,  registration,  and other Taxes and fees. If required by applicable  law,
Parent and the Company  will join in the  execution  of any such Tax Returns and
other documentation.

         5.2 EMPLOYEE  BENEFIT  PLANS.  If reasonably  requested by Parent,  the
Company  shall  terminate  any  Company  Plan  or  Company  Benefit  Arrangement
substantially contemporaneously with the Closing. Notwithstanding the foregoing,
with  respect to any Company  Plan or Company  Benefit  Arrangement  that is not
terminated  or  merged  into an  existing  Parent  plan or  benefit  arrangement
substantially   contemporaneously  with  the  Closing,  the  Stockholders  shall
cooperate  (and shall use their  reasonable  efforts to cause the  officers  and
employees of the Company that are responsible to administering  any such Company
Plan or Company  Benefit  Arrangement to cooperate) with Parent on and after the
Closing Date in  continuing  to  administer  and  maintain  such Company Plan or
Company Benefit  Arrangement in accordance  with its  constituent  documents and
with all  applicable  provisions  of the Code,  ERISA and other laws,  including
applicable federal and state securities laws,


                                       32
<PAGE>



until  such  time  as the  Company  Plan  or  Company  Benefit  Arrangement  are
terminated or merged into a Parent plan or benefit arrangement.

         5.3 RELATED PARTY AGREEMENTS.  The Company and/or the Stockholders,  as
the case may be,  shall  terminate  any Related  Party  Agreements  which Parent
requests the Company or Stockholders to terminate.

         5.4      COOPERATION.

                  (a) The Company, Stockholders and Parent shall each deliver or
cause to be delivered to the other on the Closing Date,  and at such other times
and places as shall be reasonably  agreed to, such  instruments as the other may
reasonably request for the purpose of carrying out this Agreement. In connection
therewith,  if required,  the chairman and vice  president of the Company  shall
execute any documentation  reasonably required by Parent's  Independent Auditors
(in  connection  with such  accountant's  audit of the  Company)  or the  Nasdaq
National Market.

                  (b) The  Stockholders  and the Company shall cooperate and use
their reasonable  efforts to have the present officers,  directors and employees
of the Company cooperate with Parent on and after the Closing Date in furnishing
information,  evidence,  testimony and other  assistance in connection  with any
filing obligations, actions, proceedings, arrangements or disputes of any nature
with respect to matters pertaining to all periods prior to the Closing Date.

                  (c)  Each  party  hereto  shall  cooperate  in  obtaining  all
consents and approvals  required under this Agreement to effect the transactions
contemplated hereby

         5.5      ACCESS TO INFORMATION; PUBLIC DISCLOSURE.

                  (a) Between the date of this  Agreement  and the Closing Date,
the Company  will  provide to the officers  and  authorized  representatives  of
Parent  (i)  access to all of the sites,  properties,  books and  records of the
Company, (ii) within thirty (30) days of the end of each calendar month starting

accrual basis,  and (iv) such additional  financial and operating data and other
information  as to the business and properties of the Company as Parent may from
time to time  reasonably  request,  including  without  limitation,  access upon
reasonable request to the Company's employees, customers, vendors, suppliers and
creditors for due diligence inquiry. No information or knowledge obtained in any
investigation  pursuant to this  Section 5.5 shall affect or be deemed to modify
any  representation or warranty contained in this Agreement or the conditions to
the  obligations  of the parties to  consummate  the  transactions  contemplated
hereby.  Parent  shall  bear  the  cost  of the  preparation  of  accrual  basis
statements pursuant to clause (iii) of this Section 5.5(a).

                  (b)  Prior  to  the  Closing,  neither  the  Company  nor  any
Stockholder shall make any disclosure (whether or not in response to an inquiry)

Parties in  connection  with,  resulting  from or arising  out of,  directly  or
indirectly:

                  (a)  any  breach  of any  representation  or  warranty  of the
Stockholders  or the  Company  set forth in this  Agreement  or any  schedule or
certificate,  delivered  by or on behalf of any  Stockholder  or the  Company in
connection herewith; or

                  (b) any  nonfulfillment  of any  covenant or  agreement by the
Stockholders or, prior to the Closing, the Company, under this Agreement; or

                  (c) any untrue  statement of a material  fact  relating to the

therein not misleading, and not provided to Parent or its counsel by the Company
or the Stockholders.

<PAGE>


                  (a) any breach of any  representation  or  warranty of the RIG

         8.3 LIMITATION AND EXPIRATION.  Notwithstanding  anything herein to the
contrary:

                  (a)      there shall be no liability for indemnification

                           (i)  under  Section  8.1  unless,  and  solely to the
extent that, the aggregate amount of Damages suffered by the Parent  Indemnified
Parties under the applicable provisions exceeds $150,000.00 (an "Indemnification
Threshold"); or

                           (ii)  under  Section  8.2  unless,  and solely to the
extent that, the aggregate amount of Damages suffered by the Jamison Indemnified
Parties under the applicable provisions exceeds $150,000.00 (an "Indemnification
Threshold");

provided,  however,  that neither  Indemnification  Threshold shall apply to (i)
Damages arising out of any breaches of the covenants of any Jamison Party or any
RIG  Party,  as the case may be, set forth in  Article V of this  Agreement,  or
representations  and  warranties  made in  Sections  3.4  (capital  stock of the
Company),  3.5 (transactions in capital stock of the Company),  3.24 (but solely
matters relating to the payment of past due sales taxes to the State of Texas by
the Company), and 4.4 (capital stock of Parent);

                  (b) (i) the  aggregate  amount  of the  Stockholders'  and the
Company's  (if any)  liability  under  this  Article  VIII  shall not exceed ten
percent (10%) of the Consideration (the "Stockholders' Cap"), provided, however,
that any liability  arising from or in connection  with any Final  Consideration
Adjustment  or the  representations  and  warranties  contained  in Section 3.24
(taxes) and the covenants and agreements  contained herein with respect to Taxes
shall not apply towards, nor be limited by, the Stockholders' Cap; and

                           (ii)  the  aggregate   amount  of  the  RIG  Parties'
liability  under this  Article  VIII shall not exceed ten  percent  (10%) of the
Consideration  (the "RIG Cap"),  provided,  however,  that any liability arising
from or in connection with the representations and warranties contained in


                                       43
<PAGE>


Section 4.11 (taxes) and the  covenants  and  agreements  contained  herein with
respect to Taxes shall not apply towards, nor be limited by, the RIG Cap;

                  (c) the indemnification obligations under this Section 8 or in
any certificate or writing  furnished in connection  herewith shall terminate on
the later of clause (i) or (ii) below:

                           (i)      (1)     except   as   to    representations,
warranties, and covenants specified in clause (i)(2) of this Section 8.3(c), the
first anniversary of the Closing, or

                                    (2)     with respect to representations  and
warranties  contained in Sections 3.21 (environmental  matters),  3.23 (employee
benefit plans), 3.17 (intellectual  property),  3.24 (taxes) and 4.9 (taxes), on
(A)  the  date  that is six (6)  months  after  the  expiration  of the  longest
applicable  federal  or  state  statute  of  limitation   (including  extensions
thereof), or (B) if there is no applicable statute of limitation, five (5) years
after the Closing; or

                           (ii)     the final resolution of claims or demands (a
"Claim")  pending  as of the  relevant  dates  described  in clause  (i) of this
Section 8.3(c) (such claims referred to as "Pending Claims").

         8.4   INDEMNIFICATION   PROCEDURES.   All   claims   or   demands   for
indemnification  under  this  Article  VIII  ("Claims")  shall be  asserted  and
resolved as follows:

                  (a)  In  the  event  that  any  Parent  Indemnified  Party  or
Stockholder  Indemnified Party (an "Indemnified  Party") has a Claim against any
party obligated to provide indemnification pursuant to Section 8.1 or 8.2 hereof
(the "Indemnifying Party") which does not involve a Claim being asserted against
or sought to be  collected by a third party,  the  Indemnified  Party shall with
reasonable  promptness notify the Indemnifying  Party of such Claim,  specifying
the nature of such Claim and the amount or the estimated  amount  thereof to the
extent then feasible (the "Claim Notice").  If the  Indemnifying  Party does not
notify the Indemnified  Party within thirty (30) days after the date of delivery
of the Claim Notice that the  Indemnifying  Party  disputes  such Claim,  with a
detailed statement of the basis of such position, the amount of such Claim shall
be conclusively deemed a liability of the Indemnifying Party hereunder.  In case
an objection is made in writing in  accordance  with this  Section  8.4(a),  the
Indemnified  Party shall respond in a written  statement to the objection within
fifteen (15) days and, for sixty (60) days thereafter,  attempt in good faith to
agree upon the rights of the  respective  parties  with  respect to each of such
Claims (and,  if the parties  should so agree,  a memorandum  setting forth such
agreement shall be prepared and signed by both parties).

                  (b) (i) In the event that any Claim for which the Indemnifying
Party would be liable to an Indemnified  Party hereunder is asserted  against an
Indemnified  Party by a third party (a "Third  Party  Claim"),  the  Indemnified
Party shall deliver a Claim Notice to the Indemnifying  Party . The Indemnifying
Party shall have  fifteen (15) days from date of delivery of the Claim Notice to
notify  the  Indemnified  Party (A)  whether  the  Indemnifying  Party  disputes
liability to the  Indemnified  Party  hereunder  with respect to the Third Party
Claim, and, if so, the basis for such a dispute, and (B)


                                       44
<PAGE>


if such party does not dispute liability,  whether or not the Indemnifying Party
desires,  at the sole cost and  expense  of the  Indemnifying  Party,  to defend
against the Third Party Claim,  provided  that the  Indemnified  Party is hereby
authorized (but not obligated),  prior to and during the Notice Period,  to file
any motion,  answer or other  pleading  and to take any other  action  which the
Indemnified Party shall deem necessary or appropriate to protect the Indemnified
Party's interests.

                           (ii)     In the  event  that the  Indemnifying  Party
notifies the  Indemnified  Party within the Notice Period that the  Indemnifying
Party does not dispute the  Indemnifying  Party's  obligation to indemnify  with
respect to the Third  Party  Claim,  the  Indemnifying  Party  shall  defend the
Indemnified  Party  against such Third Party Claim by  appropriate  proceedings,
provided that,  unless the Indemnified  Party otherwise  agrees in writing,  the
Indemnifying Party may not settle any Third Party Claim (in whole or in part) if
such  settlement  does not include a complete and  unconditional  release of the
Indemnified  Party. If the Indemnified  Party desires to participate in, but not
control,  any such defense or settlement the Indemnified  Party may do so at its
sole cost and  expense.  If the  Indemnifying  Party  elects  not to defend  the
Indemnified Party against a Third Party Claim,  whether by failure of such party
to give the  Indemnified  Party timely  notice as provided  herein or otherwise,
then the Indemnified  Party,  without waiving any rights against such party, may
settle or defend against such Third Party Claim in the Indemnified  Party's sole
discretion  and the  Indemnified  Party shall be  entitled  to recover  from the
Indemnifying  Party the amount of any  settlement or judgment and, on an ongoing
basis,  all  indemnifiable  costs and  expenses  of the  Indemnified  Party with
respect thereto,  including  interest from the date such costs and expenses were
incurred.

                           (iii) If at any time,  in the  reasonable  opinion of
the  Indemnified  Party,  notice  of which  shall be  given  in  writing  to the
Indemnifying  Party,  any Third Party Claim seeks  material  prospective  relief
which could have an adverse  effect on any  Indemnified  Party or the Company or
any subsidiary,  the Indemnified Party shall have the right to control or assume
(as the case may be) the defense of any such Third Party Claim and the amount of
any  judgment or  settlement  and the  reasonable  costs and expenses of defense
shall be included as part of the indemnification obligations of the Indemnifying
Party  hereunder.  If the Indemnified  Party elects to exercise such right,  the
Indemnifying Party shall have the right to participate in, but not control,  the
defense  of  such  Third  Party  Claim  at the  sole  cost  and  expense  of the
Indemnifying Party.

                           (iv) If the Indemnifying Party is a Stockholder, then
any notice  required  to be given  under this  Section 8.4 shall be given to the
Stockholders' Representative.

                  (c) Nothing herein shall be deemed to prevent the  Indemnified
Party from making a Claim, and an Indemnified  Party may make a Claim hereunder,
for  potential or  contingent  Damages  provided the Claim Notice sets forth the
specific  basis  for any such  potential  or  contingent  claim or demand to the
extent then feasible and the Indemnified Party has reasonable grounds to believe
that such Claim may be made.

                  (d) Subject to the provisions of Section 8.3, the  Indemnified
Party's failure to give reasonably prompt notice as required by this Section 8.4
of any actual, threatened or possible claim


                                       45
<PAGE>


or demand which may give rise to a right of indemnification  hereunder shall not
relieve the Indemnifying Party of any liability which the Indemnifying Party may
have to the  Indemnified  Party  except to the extent that  failure to give such
notice materially and adversely prejudiced the Indemnifying Party.

         8.5 EFFECTIVENESS OF REPRESENTATIONS  WARRANTIES.  All  representations
and  warranties  made by the  Company,  the  Stockholders,  and  each of the RIG
Parties in or pursuant to this Agreement or in any document  delivered  pursuant
hereto shall be deemed to have been made on the date of this  Agreement  (except
as otherwise provided herein) and, if a Closing occurs, as of the Closing Date.

         8.6 REMEDIES. Except for any liability based on a finding of fraud, the
exclusive  remedy of any party  hereto  arising  by reason of the  breach of any
representation  or warranty  set forth herein or the default in or breach of any
covenant, condition, agreement or undertaking by any other party hereto shall be
limited to the indemnification rights set forth in this Article VIII.

         8.7 SET OFF.  Subject only to the limitations of this Article VIII, and
without  limitation  of  any  right  of  the  Parent   Indemnified   Parties  to
indemnification  or payment under this  Agreement or applicable  law, the Parent
Indemnified  Parties shall have the obligation to seek recovery of (a) any Final
Consideration  Adjustment under Section 1.3 (but such obligation to seek set off
shall not exceed 25% of the value of the then  existing  Pledged  Assets) or (b)
any Damages under Section 8.4, first by set-off against the Pledged  Assets.  To
the extent that the liability of the Stockholders hereunder exceeds the value of
the Pledged  Assets,  Parent agrees to accept from the  Stockholders  Restricted
Shares before  seeking the delivery of any other shares or cash. For purposes of
the preceding two  sentences,  the Pledged Shares shall be valued as provided in
Section 1.4(d) above.

         8.8 SPECIAL TAX  PROVISION.  If the Company or Parent  receives any Tax
refund attributable to the period prior to the Closing,  then the amount of such
refund  shall  reduce  the  amount of  claims,  if any,  of Parent  against  the
Stockholders for breach of the representations and warranties in Section 3.24 or
of the covenants in Section 5.1.


                                  ARTICLE IX.

                                 NONCOMPETITION

         9.1 PROHIBITED ACTIVITIES. No Stockholder will, for a period of two (2)
years  following  the  Closing  Date,  for any reason  whatsoever,  directly  or
indirectly,  for  himself,  herself or on behalf of or in  conjunction  with any
other person, persons, company, partnership, corporation or business of whatever
nature:

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


                                       46
<PAGE>


or adviser, or as a sales  representative,  in any business selling any products
or services in direct competition with Parent, in the United States,  Canada, or
the United Kingdom, (the "Territory");

                  (b) call upon any  person  who is, at that  time,  within  the
Territory,  an employee of Parent in a  managerial  capacity  for the purpose or
with the  intent of  enticing  such  employee  away from or out of the employ of
Parent;

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

                  (d) call upon any prospective  acquisition candidate that was,
to the  knowledge  of  such  Stockholder,  either  called  upon by  Parent  as a
prospective  acquisition candidate or was the subject of an acquisition analysis
by Parent.  Each Stockholder,  to the extent lacking the knowledge  described in
the  preceding   sentence,   shall  immediately  cease  all  contact  with  such
prospective  acquisition  candidate  upon being  informed that Parent had called
upon such candidate or made an acquisition analysis thereof.

For purposes of this Article IX, the term "Parent"  includes all subsidiaries of
Parent  (including  without  limitation the Company and any companies Parent has
resolved to acquire).

         9.2      CONFIDENTIALITY.

                  (a) Each  Stockholder  recognizes that by reason of his or her
ownership of the Company and his or her employment by the Company, he or she has
acquired confidential  information and trade secrets concerning the operation of
the  Company,  the use or  disclosure  of which  could  cause the Company or its
affiliates  or  subsidiaries  substantial  loss and  damages  that  could not be
readily   calculated  and  for  which  no  remedy  at  law  would  be  adequate.
Accordingly,  each Stockholder  covenants and agrees with the Company and Parent
that he or she will not for a period of two (2) years following the Closing Date
(or in the case of trade secrets (as defined under  applicable  law) for so long
as  the   information   remains  a  trade  secret)   except  in  performance  of
Stockholder's  obligations  to the Company or with the prior written  consent of
the Company pursuant to authority granted by a resolution of the Board, directly
or indirectly,  disclose any secret or confidential  information  that he or she
may learn or has learned by reason of his or her ownership of the Company or his
or her employment by the Company, or any of its subsidiaries and affiliates,  or
use any such information in a manner detrimental to the interests of the Company
or Parent,  unless (i) such  information  becomes known to the public  generally
through no fault of any  Stockholder,  (ii) disclosure is required by law or the
order of any governmental  authority under color of law, or (iii) the disclosing
party  reasonably  believes that such  disclosure is required in connection with
the defense of a lawsuit against the disclosing party,  provided,  that prior to
disclosing  any  information  pursuant to clause (i),  (ii) or (iii) above,  the
Stockholder  (as  applicable)  shall give prior written notice thereof to Parent
and provide  Parent with the  opportunity  to contest such  disclosure and shall
cooperate  with  efforts  to prevent  such  disclosure.  The term  "confidential
information" includes, without limitation, information not


                                       47
<PAGE>


previously  disclosed to the public or to the trade by the Company's or Parent's
management  with  respect  to  the  Company's  or  Parent's,  or  any  of  their
affiliates' or subsidiaries',  products,  facilities, and methods, trade secrets
and other intellectual  property,  software,  source code, systems,  procedures,
manuals,  confidential reports,  product price lists, customer lists,  financial
information  (including the revenues,  costs, or profits  associated with any of
the Company's products),  business plans,  prospects, or opportunities but shall
exclude any information already in the public domain.

                  (b) The RIG Parties and their  affiliates on the one hand, and
the Jamison  Parties and their  affiliates on the other,  shall not disclose the
existence or terms of this  Agreement or the  transactions  contemplated  hereby
(whether or not in response to any inquiry) without the prior written consent of
the other  side;  provided,  however,  that the  parties  and  their  respective
affiliates  shall have the right to disclose in filings with the  Securities and
Exchange  Commission all information  relating to the transactions  contemplated
hereby required or deemed desirable to be disclosed in connection with the IPO.

         9.3 DAMAGES.  Because of the difficulty of measuring economic losses to
Parent as a result of a breach of the  foregoing  covenant,  and  because of the
immediate  and  irreparable  damage  that could be caused to Parent for which it
would have no other adequate remedy,  each Stockholder agrees that the foregoing
covenant  may be enforced by Parent in the event of breach by such  Stockholder,
by injunctions and restraining orders.

         9.4  REASONABLE  RESTRAINT.   The  parties  agree  that  the  foregoing
covenants in this Article IX impose a reasonable  restraint on each  Stockholder
in light of the  activities  and business of Parent on the date of the execution
of this  Agreement,  assuming the  completion of the  transactions  contemplated
hereby, and the current plans of Parent; but it is also the intent of Parent and
each  Stockholder  that such  covenants be construed  and enforced in accordance
with the changing  activities and business of Parent throughout the term of this
covenant.  The parties  further  agree that so long as a  Stockholder  is not an
employee of the Company,  in the event a Stockholder shall enter into a business
or pursue other activities not in competition with Parent or similar  activities
or business in locations the operation of which, under such circumstances,  does
not violate Section 9.1(a) or the terms of any employment agreement with Parent,
such Stockholder  shall not be chargeable with a violation of this Article IX if
Parent shall thereafter  enter the same,  similar or a competitive (a) business,
(b) course of activities or (c) location, as applicable.

         9.5  SEVERABILITY;  REFORMATION.  The  covenants in this Article IX are
severable and separate,  and the unenforceability of any specific covenant shall
not affect the  provisions  of any other  covenant.  Moreover,  in the event any
court  of  competent  jurisdiction  shall  determine  that  the  scope,  time or
territorial restrictions set forth are unreasonable, then it is the intention of
the parties that such  restrictions  be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.

         9.6 INDEPENDENT COVENANT. All of the covenants in this Article IX shall
be  construed  as an  agreement  independent  of any  other  provision  in  this
Agreement, and the existence of any claim


                                       48
<PAGE>


or cause of action of any Stockholder against Parent, whether predicated on this
Agreement or otherwise,  shall not  constitute a defense to the  enforcement  by
Parent of such covenants.  The parties expressly  acknowledge that the terms and
conditions of this Article IX are independent of the terms and conditions of any
other  agreements  including,  but not  limited  to, any  employment  agreements
entered into in connection with this Agreement.  It is specifically  agreed that
the period of two (2) years  stated at the  beginning  of this Article IX during
which the  agreements and covenants of the  Stockholder  made in this Article IX
shall be effective,  shall be computed by excluding  from such  computation  any
time during which the Stockholder is found by a court of competent  jurisdiction
to have been in  violation of any  provision  of this Article IX. The  covenants
contained  in  Article  IX shall  not be  affected  by any  breach  of any other
provision  hereof  by  any  party  hereto  and  shall  have  no  effect  if  the
transactions contemplated by this Agreement are not consummated.

         9.7 MATERIALITY. The Company and each Stockholder hereby agree that the
covenants  set forth in this Article IX are a material and  substantial  part of
the  transactions   contemplated  by  this  Agreement,   supported  by  adequate
consideration.


                                   ARTICLE X.

                                    GENERAL

         10.1 TERMINATION. This Agreement may be terminated at any time prior to
the Closing Date solely:

                  (a) by mutual consent of the boards of directors of Parent and
the Company; or

                  (b) by the Stockholders and the Company as a group, on the one
hand, or by Parent, on the other hand, if the Closing shall not have occurred on
or before May 25, 1998 and no alternative  pricing  methodology (as described in
Section 1.2(a)) has been agreed to; or

                  (c) by the Stockholders and the Company as a group, on the one
hand,  or by  Parent,  on the  other  hand,  if there is or has been a  material
breach,  failure to fulfill or default on the part of the other  party (with the
Stockholders  and the Company  deemed to be a single party for this  purpose) of
any of the  representations  and warranties  contained  herein or in the due and
timely  performance  and  satisfaction  of any of the  covenants,  agreements or
conditions  contained herein, and the curing of such default shall not have been
made or shall not reasonably be expected to occur before the Closing Date; or

                  (d) by the Stockholders and the Company as a group, on the one
hand, or by Parent,  on the other hand, if there shall be a final  nonappealable
order of a federal  or state  court in  effect  preventing  consummation  of the
transactions  contemplated  hereby;  or there shall be any action taken,  or any
statute,  rule  regulation  or order  enacted,  promulgated  or issued or deemed
applicable


                                       49
<PAGE>


to the transactions  contemplated  hereby by any governmental entity which would
make the consummation of the transactions contemplated hereby illegal.

         10.2     EFFECT OF TERMINATION.

                  (a) In the event of the termination of this Agreement pursuant
to Section 10.1 for a Qualifying  Purpose (defined below),  this Agreement shall
forthwith  become  ineffective,  and no party  hereto or any of their  officers,
directors or shareholders shall have any liability or obligation hereunder, and,
with respect to such  termination for a Qualifying  Purpose,  the parties hereby
release  and  covenant  and agree not to sue the other  parties  hereto  for any
Damages suffered, sustained or incurred for such termination.

                  (b) In the event of the termination of this Agreement pursuant
to  Section  10.1  for  other  than a  Qualifying  Purpose  (including,  without
limitation, termination by any party for the failure by the other party to close
the Transaction),  then this Agreement shall become ineffective except that: (i)
the provisions of Articles VIII and X and Section 9.2 shall remain in full force
and effect and survive any  termination  of this  Agreement  and (ii) each party
shall remain liable to the other for such breach of this Agreement  prior to its
termination.

                  (c) For  purposes  of this  Section  10.2:  (i) a  "Qualifying
Purpose"   means  an   "Equity   Shortfall,"   a  breach   of  the   "Qualifying
Representations,  Warranties or Covenants" or a "Non-Material  Breach";  (ii) an
"Equity  Shortfall"  means that the  underwriter has notified any of the parties
that it expects that the IPO will produce an implicit  valuation  for all of the
Parent's  equity (valued at the Share Price) of less than $75 million,  and none
of the RIG Parties has previously  given written  notice to the Jamison  Parties
(acting  in good  faith) of a  material  breach  of any of the  representations,
warranties,  covenants and agreements  that are not Qualifying  Representations,
Warranties  or  Covenants  or  are  other  than  Non-Material  Breaches;   (iii)
"Qualifying    Representations,    Warranties   or   Covenants"    means   those
representations,  warranties  and/or  covenants  set forth in Sections 3.10 (but
only to the extent of litigation that was unknown and not reasonably foreseeable
as of the date  hereof),  3.16(c)  (but only to the extent  relating to ordinary
wear and tear),  3.17 (but only to the extent of litigation that was unknown and
not reasonably foreseeable as of the date hereof),  3.22(g),  3.25(a),  3.27(a),
3.27(m),  3.28,  4.4(a),  4.4(b), 4.6 (but only to the extent of litigation that
was unknown and not reasonably foreseeable as of the date hereof), 4.8 (but only
to the extent of litigation  that was unknown and not reasonably  foreseeable as
of the date  hereof),  4.12(a),  5.6(a),  5.6(b),  5.6(e) and 5.7(k)  (provided,
however,  Sections 5.6(a), 5.6(b), 5.6(e) and 5.7(k) shall constitute Qualifying
Representations,   Warranties   or  Covenants   only  to  the  extent  that  the
Stockholders  had no  knowledge  of the  action(s)  giving  rise to the claim of
breach);   and  (iv)  a   "Non-Material   Breach"   means  any   breach  of  the
representations, warranties, covenants or agreements set forth herein that could
not reasonably be expected,  individually or in aggregate,  to be likely to lead
to the loss by any or all of the RIG  Parties,  on the one hand,  or the Jamison
Parties, on the other, of greater than $150,000.

         10.3  SUCCESSORS  AND  ASSIGNS.  This  Agreement  and the rights of the
parties  hereunder may not be assigned (except by operation of law) and shall be

counterparts  and any party  hereto may  execute any such  counterpart,  each of

         10.6  BROKERS  AND  AGENTS.  The RIG  Parties on the one hand,  and the
Jamison  Parties on the other,  each  represent and warrant to the other that it
has not  employed  any  broker  or agent  in  connection  with the  transactions
contemplated  by this  Agreement  and agrees to indemnify  the other against all

and the  RIG  Parties  shall  bear  the  expense  of  converting  the  financial
statements of the Company to the accrual  method of  accounting  and the cost of

         10.9     GOVERNING LAW.

                  (a)  This  Agreement  shall  be  governed  by  and  construed,
interpreted and enforced in accordance with the laws of Delaware

                  (b) Any disputes  arising out of, in  connection  with or with
respect to this  Agreement,  the  subject  matter  hereof,  the  performance  or
non-performance  of  any  obligation  hereunder,  or  any  of  the  transactions
contemplated  hereby   ("Disputes")  that  seek  specific   performance  of  any
obligations  hereunder or injunctive  relief may be  adjudicated in any court of
competent civil jurisdiction.

                  (c) Except as provided in Section 10.9(b),  all Disputes shall
be resolved by binding  arbitration  administered  by the  American  Arbitration
Association  ("AAA") and, except as expressly provided in this Agreement,  shall
be conducted in accordance  with the Expedited  Procedures  under the Commercial
Arbitration  Rules of the AAA,  as such rules may be  amended  from time to time
(the "Rules").

                           (i)  The  hearing   locale  shall  be  determined  in
accordance with the Rules. A single, neutral arbitrator (the "Arbitrator") shall
be appointed by the AAA, within thirty (30) days after an Arbitrated  Dispute is
submitted  for  arbitration  under this  Section  10.9(c),  to preside  over the
arbitration and resolve the Dispute.  The Arbitrator  shall be selected from the
AAA's  Commercial  Panel, and shall be qualified to practice law in at least one
jurisdiction  in the United States and have expertise in the  interpretation  of
commercial contracts.  The parties shall have ten (10) days to object in writing
to the appointment of the Arbitrator, the sole basis for such objection being an
actual conflict of interest.  The AAA, in its sole  discretion,  shall determine
within ten (10) days the  validity of any  objection to the  appointment  of the
Arbitrator based on an actual conflict of interest.

                           (ii) The Arbitrator's decision (the "Decision") shall
be binding,  and the  prevailing  party may enforce the Decision in any court of
competent jurisdiction.

                           (iii) The  parties  shall use their  best  efforts to
cooperate with each other in causing the  arbitration to be held in as efficient
and expeditious a manner as practicable, including but not limited to, providing
such documents and making  available  such of their  personnel as the Arbitrator
may request,  so that the Decision may be reached timely.  The Arbitrator  shall
take  into  account  the  parties'  stated  goal  of  expedited  proceedings  in
determining  whether to authorize discovery and, if so, the scope of permissible
discovery and other hearing and pre-hearing procedures.

                           (iv) The authority of the Arbitrator shall be limited
to deciding liability for, and the proper amount of, a Claim, and the Arbitrator
shall have no authority to award punitive  damages.  The  Arbitrator  shall have
such powers and establish such  procedures as are provided for in the Rules,  so
long as such powers and procedures are consistent  with this Section 10.9(c) and
are necessary to resolve the Dispute  within the time periods  specified in this
Agreement. The Arbitrator


                                       53
<PAGE>


shall render a Decision within sixty (60) days after being appointed to serve as
Arbitrator,  unless the  parties  otherwise  agree in writing or the  Arbitrator
makes a finding  that a party has carried the burden of showing good cause for a
longer period.

         10.10  SEVERABILITY.   If  any  provision  of  this  Agreement  or  the
application   thereof  to  any  person  or  circumstances  is  held  invalid  or
unenforceable in any jurisdiction,  the remainder hereof, and the application of
such provision to such person or circumstances in any other jurisdiction,  shall
not be affected thereby,  and to this end the provisions of this Agreement shall
be severable.  The preceding  sentence is in addition to and not in place of the
severability provisions in Section 9.5.

         10.11 ABSENCE OF THIRD PARTY  BENEFICIARY  RIGHTS. No provision of this
Agreement is intended,  nor will any provision be interpreted,  to provide or to
create any third party beneficiary rights or any other rights of any kind in any
client,  customer,  affiliate,  shareholder,  employee  or  partner of any party
hereto or any other person or entity.

         10.12 MUTUAL  DRAFTING.  This  Agreement  is the mutual  product of the
parties  hereto,  and each  provision  hereof  has been  subject  to the  mutual
consultation, negotiation and agreement of each of the parties, and shall not be
construed for or against any party hereto.

         10.13   FURTHER   REPRESENTATIONS.   Each   party  to  this   Agreement
acknowledges  and  represents  that it has  been  represented  by its own  legal
counsel in connection with the transactions contemplated by this Agreement, with
the  opportunity  to seek advice as to its legal rights from such counsel.  Each
party further  represents that it is being  independently  advised as to the tax
consequences  of the  transactions  contemplated  by this  Agreement  and is not
relying on any  representation  or statements made by the other party as to such
tax consequences.
