"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

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.

sustained  after the  Offering.  It is  currently  anticipated  that the initial
public  offering  price  will be  between  $10.00  and  $12.00  per  share.  See
"Underwriting"  for a discussion of the factors to be considered in  determining
the initial public  offering  price.  The Company has applied to have the Common
Stock quoted on the Nasdaq National Market under the symbol "RIGX."

                                   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 140,000
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 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 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 

                                        3

<PAGE>



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 1,600 clients,  including  leaders of the commercial  real estate  industry
such as CB Commercial  Real Estate  Group,  Inc.,  Grubb & Ellis,  Trammell Crow
Company,  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.  The
principal components of the Company's strategy are:

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

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

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

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

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

     The  Company  was formed in  February  1998 by RIGINC and RIGLP to acquire,
directly or indirectly, all of the outstanding equity interests in RIGINC, RIGLP
and Jamison.  RIGINC,  which was  incorporated  and  organized  initially in the
District of Columbia,  operated  the  Company's  business  until  November  1994
(RIGINC  was  reincorporated  under the laws of  Delaware  in 1996).  RIGINC was
formerly  known as "Realty  Information  Group,  Inc.";  in connection  with the
formation of the Company and this  Offering,  RIGINC was renamed "OLD RIG, Inc."
RIGLP, a Delaware limited partnership,  was organized by RIGINC in November 1994
to hold and operate the Company's business.  The Company maintains its executive
offices at 7475  Wisconsin  Avenue,  Bethesda,  Maryland  20814.  The  Company's
telephone number is (301) 215-8300.

- ----------
(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 and (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.  See  "Underwriting,"
     "Management -- Employee Benefit Plans,"  "Description of Capital Stock" and
     "Certain Transactions."

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


                  TRANSACTIONS IN CONNECTION WITH THE OFFERING

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

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

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

(3)  Reflects  charges  of  approximately   $1.1  million   resulting  from  the
     amortization  of  capitalized  product  development  acquired  through  the
     Jamison Acquisition.

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

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

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

(7)  Adjusted to reflect the sale of 2,109,091 shares of Common Stock offered by
     the Company and the  application  of the net  proceeds  from the  Offering.
     Additionally,  reflects the use of proceeds for the  repayment of the RIGLP
     line of credit of $1,000,000 and its  subordinated  debt to RIGINC totaling
     $650,000  (which sum was loaned to RIGINC by one of its  stockholders)  and
     the advances from  stockholders  of Jamison of $111,000 and other long-term
     debt of Jamison amounting to $67,000. See "Certain Transactions."

                                  RISK FACTORS

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

     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  $11.4  million as of
December 31, 1997.  The Company  intends to continue to invest in expansion and,
therefore, to sustain substantial losses for the next several years. The ability
of the  Company to achieve  overall  profitability  will  largely  depend on its
ability to generate  revenue  from its  products  and  services in excess of its
investment in geographic and product  expansion.  There can be no assurance that
the  Company  will be able to generate  revenue  that is  sufficient  to achieve
profitability,  to maintain  profitability  on a quarterly or annual basis or to
sustain or increase its revenue growth in future periods.

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

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

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

     Dependence on Integrity and  Reliability of Software and the Database.  The
Company's  success  is  highly  dependent  on  its  clients'  confidence  in the
comprehensiveness,  accuracy  and  reliability  of the Database and the software
accessing the  Database.  Although the Company  believes that it takes  adequate
precautions  to safeguard the  completeness  and  consistency of the data in the
Database,  and that the  information  contained  in the  Database  is  generally
current,  comprehensive  and accurate,  the task of establishing and maintaining
such quality during growth is challenging.  Similarly,  it requires  substantial
effort and expense to maintain and improve the software  that allows  clients to
access the  Database.  There can be no  assurance  that the  Company can sustain
those  efforts.  See "Business -- Strategy,"  "-- Database" and "-- Products and
Services"

     Dependence on the Real Estate Industry. The Company's business is dependent
on the real estate industry and related industries that supply goods or services
to, or invest  in,  the real  estate  industry.  Therefore,  changes in the real
estate  market may affect  demand for the  Company's  products.  The real estate
industry traditionally has been subject to cyclical economic swings, which could
adversely affect

                                        8

<PAGE>



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.  While 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 maintains a 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 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

                                        9

<PAGE>



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 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  1,000,000  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 2,659,711 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

                                       10

<PAGE>



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.  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.

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

     Dilution to New  Investors;  Absence of Dividends.  Purchasers of shares of
Common Stock in the Offering will experience  immediate and substantial dilution
of $8.29 per share in pro forma net tangible book value per share.  In addition,
purchasers  of shares of Common  Stock in the  Offering  will  incur  additional
dilution to the extent  outstanding  options and  warrants  are  exercised.  See
"Dilution."  The Company has never  declared or paid any dividends on the Common
Stock and does not  anticipate  paying any  dividends on the Common Stock in the
foreseeable future. See "Dividend Policy."

                                 USE OF PROCEEDS


     The  gross  proceeds  to be  received  by the  Company  from the sale of an
estimated  2,109,091  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 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  December  31,  1997,  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  $3.6  million  or $.52 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 December 31, 1997,  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  December  31,  1997  would  have  been
approximately  $24.2  million or $2.71 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
$8.29 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.

 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  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.

                                       17

<PAGE>



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

SUPPLEMENTAL REVENUE AND CONTRIBUTION MARGIN ANALYSIS OF ESTABLISHED REGIONS

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

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

     As of December 31, 1997, 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 December 31,
1997,  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.

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,  Jamison
generated  cash from operating  activities of $266,000.  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.  Additionally,  it is
estimated that as a result of the resignation of one Jamison stockholder and the
terms of an  employment  agreement  with  the  other  stockholder,  compensation
expense  will be reduced by an estimated  $300,000  annually.  Therefore,  a net
total of $1.2 million in increased annual charges are anticipated in each of the
first two years after the acquisition.

     The Company will make significant investments to convert Jamison's data and
to upgrade Jamison's clients to the Company's  products.  This entire process is
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 of Jamison's  data,  products and clients will be
completed in the time planned, or that the cost of these conversions will not be
greater than estimated.

     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  and  $903,000 as of  December  31,  1996 and 1997,  respectively.  The
Company had a deficit in working  capital at December 31, 1997 of $1.5  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 princi-

                                       20

pally 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 140,000
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


                                       22

<PAGE>



an independent 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.

                                       23

     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

                                       24

<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 140,000  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 108,000 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


                                       25

<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.

                                       26

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


                                       27

<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


                                       28

<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 1,600  clients,  including  leaders of the
commercial real estate  industry such as CB Commercial Real Estate Group,  Inc.,
Grubb & Ellis,  Trammell Crow Company,  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.


                                       29

<PAGE>



     The Company has won  several  national  awards over the last two years as a
result of its in-house Marketing Group. The Company was the National Association
of  Industrial  and Office  Properties  1996 winner "Best Single Ad to Promote a
Company,"  the 1997 1st Place  winner "Ad Campaign to Promote a Company" for New
York CoStar and the 1998 1st Place & Grand Award winner  "Electronic  Marketing"
for the Company's web site. The Company's web site has received  numerous awards
including the National  Association of Industrial and Office Properties  (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


                                       30

<PAGE>



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

PROPRIETARY RIGHTS

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

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

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

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

EMPLOYEES

     As of December  31,  1997,  the Company  employed a total of 142  full-time
employees.  Upon  consummation of the  acquisition of Jamison,  the Company will
employ approximately 187 full-time  employees,  including 133 researchers and 32
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.

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.

EMPLOYEE BENEFIT PLANS

     The Company  currently  anticipates  that its Board of Directors will adopt
the Stock Option Plan at or prior to  consummation of the Offering and that such
plan will be submitted for  stockholder  approval at the next annual  meeting of
stockholders.  The Company has  reserved  1,000,000  shares of Common  Stock for
issuance under the Stock Option Plan.  Unless  terminated sooner by the Board of
Directors, the Stock Option Plan will terminate in April 2006.

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

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


                          JAMISON SELLING STOCKHOLDERS

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

                              CERTAIN TRANSACTIONS


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

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

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

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


                                       38

<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-


                                       39

<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  2,659,711  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


                                       40

<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- 


                                       41

<PAGE>



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 December  31, 1997,
options  issued  pursuant to the Stock  Option  Plan to  purchase  approximately
409,297  shares were  outstanding,  of which options to purchase  256,128 shares
were 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 2,659,711 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.

</TABLE>


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

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

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

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

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

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

     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.

     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.

                         REALTY INFORMATION GROUP, INC.

                       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  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 December  31,  1997.  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.

                         REALTY INFORMATION GROUP, INC.
                          NOTES TO UNAUDITED PRO FORMA

                     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,  its predecessors and Jamison
as of  December  31,  1997 and for the year  then  ended.  The  related  audited
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 expects to 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 December 31, 1997.  Such
amounts may be subject to change based on  additional  information  arising at a
later date. The actual  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.

     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 one
year 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 to cost of sales for product amortization
               and $400,000 to  operating  expenses  for  amortization  of other
               assets,  which is offset by $300,000 in estimated  reductions  in
               compensation  to the  former  Jamison  stockholders,  based on an
               ongoing   employment   agreement  for  one  stockholder  and  the
               resignation of the other stockholder. These adjustments result in
               a net increase to pro forma losses in 1997 of $1,200,000.

          (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.

          (c)  Loss from  investment in RIGLP recorded in the accounts of RIGINC
               is eliminated.

     Pro forma condensed combined balance sheet:

          (d)  Inter-company  accounts of RIGINC and its investment in RIGLP are
               eliminated against the accounts of its subsidiary, RIGLP

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

     Offering adjustment:



          (f)  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
               $1,790,114  in current  debts and $37,449 in long term debt for a
               total of  $1,827,563,  resulting  in an  increase  in cash of the
               Company  from  the   Offering,   after   repayment  of  debt,  of
               $18,772,437.

4.   WEIGHTED AVERAGE SHARES OUTSTANDING

               Includes 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 shares issued to the Jamison  stockholders  in connection
               with the  acquisition  of Jamison.  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.


3. PLANNED TRANSACTIONS

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

     We conducted  our audits in accordance  with  generally  accepted  auditing

                         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).

     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.

     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 and
$287,000 of expense related to the capitalized product development costs for the
years ended December 31, 1995, 1996 and 1997, 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.  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, and $397,966 for
the years ended December 31, 1995, 1996, and 1997, respectively.

     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.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

     Recent Pronouncements

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

     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. 


3.   ACQUISITIONS

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

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

5.   LINE OF CREDIT

     In October,  1997, 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 in the
event of an  initial  public  offering  or an equity  funding  in excess of $5.0
million.  The warrants have a three year term and provide for the purchase of an
equivalent  number  of shares at a price of 10% less than the price of the stock
sold in an  initial  public  offering  or an  equity  funding  in excess of $5.0
million. At December 31, 1997, $650,000 of borrowings were outstanding under the
commitment  and have been  advanced  to  RIGLP.  Interest  paid in 1997  totaled
$8,055. 

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


7.   COMMITMENTS

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

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


              1998 ........................    $   869,100

                                               ===========


     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.

</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.

     The  following  table   summarizes   information   regarding  unit  options
outstanding at December 31, 1997:

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors OLD RIG, Inc.

     We have  audited the  accompanying  balance  sheets of OLD RIG,  Inc. as of
December  31,  1996  and  1997,  and  the  related   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 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.

                          NOTES TO FINANCIAL STATEMENTS

1.   ORGANIZATION

     OLD RIG, Inc.,  ("RIGINC")  formerly Realty  Information  Group,  Inc., was
formed on November 5, 1987 for the purpose of  investing  in Realty  Information
Group,  L.P.  ("RIGLP"),  a provider of information  services for the office and
industrial real estate industry, and has no operations of its own.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

     In these parent-company only financial  statements,  RIGINC's investment in
RIGLP is stated at cost plus equity in undistributed earnings of RIGLP since the
date  of  acquisition.  RIGINC's  share  of net  income  of  its  unconsolidated
partnership is included in the Statement of Operations using the equity method.

     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.

     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.


3.   INVESTMENT IN RIGLP

     At December  31,  1997,  RIGINC had a 55%  interest  in, and is the general
partner of RIGLP. Although RIGINC has a controlling financial interest in RIGLP,
the  financial  statements  have  not  been  consolidated  since  the  ownership
interests of both  entities are combining in  connection  with the  contribution
agreement  and initial  public  offering,  and  consolidation  would not provide
meaningful information. RIGINC guarantees the $1,000,000 bank debt of RIGLP.


4.   RELATED PARTY TRANSACTIONS

     During 1997,  RIGINC  borrowed  funds from a  stockholder,  which were then
advanced to RIGLP. The related interest income and expense charged at prime plus
2% have no net effect on the financial statements.


5.   COMMON STOCK

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


6.   SUBSEQUENT EVENTS

     In March 1998,  RIGINC  entered into an Agreement and Plan of  Contribution
("Agreement")  by and among RIGLP,  the newly formed Realty  Information  Group,
Inc. (the  "Company"),  the  stockholders of RIGINC and the partners of RIGLP to
contribute all of RIGINC's outstanding common stock to Realty Information Group,
Inc. in exchange for common stock of Realty Information Group, Inc.

                         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.

Revenue Recognition

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

Cash and Cash Equivalents

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

Property and Equipment

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

Capitalized Product Development Costs

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

Concentration of Credit Risk

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

                   NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

Income Taxes

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

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.

     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. 


3.   COMMITMENTS

Operating Leases

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

                   1998 ........................  $ 170,200

3.   COMMITMENTS - (CONTINUED)

     Employment Agreements

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

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


4.   RELATED PARTY TRANSACTIONS

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

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

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


5.   INCOME TAXES

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

6.   NON CASH TRANSACTIONS

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


7.   MANAGEMENT'S PLANS

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

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 13. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

     Estimated  expenses in connection with the issuance and distribution of the
securities  being  registered,  other  than  underwriting  compensation,  are as
follows:



   Securities and Exchange Commission registration fee .............    $ 11,000
   National Association of Securities Dealers, Inc. filing fee .....       4,000
   Nasdaq National Market entry fee ................................      50,000

   Miscellaneous ...................................................     182,500
                                                                        --------
    Total ..........................................................    $950,000
                                                                        ========


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

     The  foregoing,   except  for  the   Securities  and  Exchange   Commission
registration fee, the National  Association of Securities  Dealers,  Inc. filing
fee and the Nasdaq National Market entry fee, are estimates.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

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

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

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     (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.

<PAGE>


     2.  REPRESENTATIONS,  WARRANTIES  AND  AGREEMENTS  OF THE  COMPANY  AND THE
SELLING STOCKHOLDERS.

     As used in this Section 2, the "Company" shall mean each of the Company
and,  where  applicable,  each of Realty  Information  Group,  L.P.,  a Delaware
limited  partnership  ("RIGLP"),  and Old  RIG,  Inc.,  a  Delaware  corporation
("RIGINC",  formerly  Realty  Information  Group,  Inc.),  predecessors  to  the
Company, with respect to the business and operations of the Company as conducted
through the First Closing Date  (hereinafter  defined).  "Related  Transactions"
shall  mean each of (i) the  transactions  to be  consummated  pursuant  to that
certain  Agreement  and Plan of  Contribution  dated  March ___,  1998 among the
Company,  the stockholders of RIGINC and the limited partners of RIGLP (the "RIG

          (a) The  Company  represents  and  warrants  to and  agrees  with each
     Underwriter that:

               (i) A registration  statement on Form S-1 (File No. 333-________)
          with  respect  to  the  Shares,   including  a  preliminary   form  of
          prospectus, copies of which have heretofore been delivered to you, has
          been prepared by the Company in conformity  with the  requirements  of
          the Securities Act of 1933, as amended (the "Act"),  and the rules and
          regulations  (the  "Rules  and  Regulations")  of the  Securities  and
          Exchange  Commission  (the  "Commission")  under the Act, and has been
          filed with the Commission  under the Act; such amendment or amendments
          to such registration  statement,  copies of which have heretofore been
          delivered  to you,  as may have  been  made  prior to the date of this
          Agreement  have been so  prepared  and filed;  and the  Company has so
          prepared  and  proposes  so to  file  in a  timely  manner  after  the
          effective  date of  such  registration  statement  the  final  form of
          prospectus.   Such  registration  statement  (including  all  exhibits
          thereto),   as  finally  amended  and  revised  as  of  the  time  the
          Underwriters  first  offer the Shares for sale to the public  together
          with  information,   if  any,  which  is  permitted  to  be,  and  is,
          subsequently filed pursuant to Rule 430A of the Rules and Regulations,
          is herein referred to as the "Registration Statement". Such prospectus
          in  the  form  filed   pursuant  to  Rule  424(b)  of  the  Rules  and
          Regulations,  or, if no final  prospectus is filed with the Commission
          pursuant  to Rule  424(b),  in such form as such final  prospectus  is
          included in the Registration  Statement,  is herein referred to as the
          "Prospectus".  Each  preliminary form of prospectus is herein referred
          to as a "Preliminary Prospectus".

               (ii) The  Commission  has not  issued  any  order  preventing  or
          suspending  the  use of any  Preliminary  Prospectus.  At the  time of
          filing of each Preliminary Prospectus, such prospectus did not include
          any untrue  statement of a material fact or omit to state any material
          fact required to be stated therein or necessary

                                      -2-

<PAGE>


          to make the statements  therein not misleading.  When the Registration
          Statement becomes effective and at all times subsequent  thereto up to
          and at each Closing Date  (hereinafter  defined) (i) the  Registration
          Statement and Prospectus  and any  amendments or  supplements  thereto
          will contain as of their respective dates all material  statements and
          information  which are required to be included  therein in  accordance
          with  the Act and  Rules  and  Regulations  and  will in all  material
          respects  conform  to the  requirements  of the Act and the  Rules and
          Regulations,  and (ii)  neither  the  Registration  Statement  nor the
          Prospectus,  nor any amendment or supplement thereto,  will include as
          of their  respective  dates any untrue statement of a material fact or
          omit to state any  material  fact  required  to be stated  therein  or
          necessary to make the  statements  therein not  misleading;  provided,
          however,  that the foregoing  representations and warranties shall not
          apply to  information  contained in or omitted  from the  Registration
          Statement or the  Prospectus  or any such  amendment or  supplement in
          reliance upon, and in conformity with, written  information  furnished
          to the Company by any Underwriter  through you specifically for use in
          the preparation thereof.

               (iii)  Set  forth  on  Schedule  B  hereto  is the  name  of each
          subsidiary  of the Company  which holds assets or conducts  operations
          which are material to the condition (financial or otherwise),  results
          of  operations,  business  or  prospects  of the Company and each such
          subsidiary taken as a whole and, unless otherwise  indicated  thereon,
          the Company  holds all right,  title and interest in and to the entire
          equity  interest in each such  subsidiary.  Except as described in the
          Prospectus, subsequent to the respective dates as of which information
          is given in the Registration Statement and the Prospectus, neither the
          Company,  nor any entity which is either  identified in the Prospectus
          as a  subsidiary  of the Company or listed on Schedule B hereto  (each
          individually  a "Subsidiary"  and  collectively  the  "Subsidiaries"),
          taken as a whole,  has  incurred  any  direct  or,  to the best of the
          Company's  knowledge,  contingent  material  liabilities  or  material
          obligations,  or entered into any material  transactions  or contracts
          not in the  ordinary  course of  business,  and there has not been any
          change in its capital  shares,  options or warrants,  nor any material
          increase or decrease in the amount  thereof  outstanding  or in any of
          its long-term debt  outstanding,  except  pursuant to the terms of the
          instruments  governing the same, or any material adverse change in the
          condition (financial or otherwise), results of operations, business or
          prospects of the Company and the Subsidiaries taken as a whole.

               (iv)  Except  as set  forth in the  Prospectus,  there is not now
          pending or, to the knowledge of the Company,  threatened,  any action,
          suit or proceeding  to which the Company or any  Subsidiary is a party
          before any court or governmental  agency or body which might result in
          any material adverse change in the condition (financial or otherwise),
          results of  operations,  business or  prospects of the Company and the
          Subsidiaries  taken as a  whole,  or might  materially  and  adversely
          affect  the   properties,   assets  or  ability  to  do   business  as
          contemplated  in the  Prospectus  of the Company and the  Subsidiaries
          taken as a whole; and there are no contracts or documents required

                                      -3-

          to be filed as exhibits to the Registration Statement by the Act or by
          the Rules and Regulations which have not been filed as exhibits to the

               (v)  This  Agreement,  the  RIG  Contribution  Agreement  and the
          Jamison Contribution Agreement have been duly authorized, executed and
          delivered on behalf of the Company,  RIGINC and RIGLP,  as applicable,

          except  (1)  that  such  enforcement  may be  subject  to  bankruptcy,
          insolvency,  reorganization,  moratorium  or other similar laws now or
          hereafter in effect relating to creditors' rights, (2) that the remedy
          of specific  performance  and  injunctive and other forms of equitable
          relief may be subject to equitable  defenses and to the  discretion of
          the court before which any proceeding  therefor may be brought and (3)
          as rights to indemnity  or  contribution  hereunder  may be limited by
          federal  or  state  securities  laws;  the  execution,   delivery  and
          performance of this Agreement,  the RIG Contribution Agreement and the
          Jamison   Contribution   Agreement   and  the   consummation   of  the
          transactions herein contemplated and the Related Transactions will not
          result  in a breach  or  violation  of any term or  provision  of,  or
          constitute  a default  under,  any  currently  existing  statute,  any
          indenture,  mortgage, deed of trust, note agreement or other agreement
          or instrument to which the Company,  RIGINC and RIGLP,  as applicable,

          Subsidiaries  is now in default,  and no event has occurred which with

          Statement,  and  is  duly  qualified  to  do  business  as  a  foreign
          corporation  or  limited  partnership  in good  standing  in all other

          to any material  properties of the Company which would have a material
          adverse  effect on the condition  (financial or otherwise)  results of
          operations, business or prospects of the Company and the Subsidiaries,
          taken as a whole, or expose it to liabilities  material to the Company

               (vii) The  Company has the  authorized  and  outstanding  capital
          stock set forth in the Prospectus;  the  outstanding  capital stock of
          the  Company  conforms,  and the Shares when issued and sold as herein
          contemplated will conform, in all material respects, to all statements
          in relation thereto  contained in the  Registration  Statement and the

          with  respect  to the  Shares  and  there are no  outstanding  rights,
          options or warrants to acquire any  securities of the Company;  to the
          extent that any rights,  options or warrants to acquire any securities
          of the Company are  outstanding,  except as otherwise set forth in the
          Prospectus,  the issuance of the Shares as described in the Prospectus
          will not result in an  adjustment  of the exercise  price or number of
          shares  issuable  upon the  exercise  in respect  of any such  rights,
          options  or  warrants;  and,  except  as  otherwise  set  forth in the
          Prospectus,  the Company  owns  (directly or  indirectly)  under valid
          title  the  respective  outstanding  shares  of  capital  stock of the

          patent licenses,  trademarks,  service marks and trade names necessary
          to carry on its  business as  presently  conducted,  and except as set
          forth  in  the  Prospectus,   neither  the  Company  nor  any  of  the
          Subsidiaries  has received any notice of  infringement  of or conflict
          with  asserted  rights of others with respect to any  patents,  patent
          licenses, trademarks, service marks or trade names which, singly or in
          the aggregate,  if the subject of an unfavorable  decision,  ruling or
          finding,   could   materially  and  adversely   affect  the  condition
          (financial or otherwise),  earnings, affairs, business or prospects of
          the Company and the Subsidiaries taken as a whole.

               (ix) Except as stated in the  Prospectus,  the  Company  holds in
          good   standing   or  has   applied   for   all   licenses,   permits,
          authorizations, franchises, consents and orders of all federal, state,
          local,  and  foreign  governmental  bodies  necessary  to carry on its
          business as reflected or  contemplated  in the  Prospectus;  except as
          stated in the Prospectus the Company has good and marketable  title to
          all personal  property owned by it, in each case free and clear of all
          liens,  encumbrances  and  defects  with  such  exceptions  as are not
          material to the Company and the Subsidiaries taken as a whole; and the
          real property and personal  property  referred to in the Prospectus as
          held under lease by the Company is held by it under valid,  subsisting
          and  enforceable  leases with only such exceptions as in the aggregate
          are not material and do not materially interfere with

                                      -5-

<PAGE>


          the conduct of the business of the Company and the Subsidiaries  taken
          as a whole as contemplated by the Prospectus.

               (x) To the best of its  knowledge,  the Company is conducting and
          proposes  to  conduct  its  business  so as to comply in all  material
          respects  with  all  applicable  federal,  state,  local  and  foreign
          governmental statutes, rules and regulations;  and except as set forth
          in the  Prospectus,  neither the Company nor any Subsidiary is charged
          with,  or,  to the  best of the  knowledge  of the  Company,  is under
          investigation  with respect to, any violation of any of such statutes,
          rules or  regulations  or is the subject of any pending or  threatened
          proceeding by any governmental body or regulatory  authority  relating
          to any such violation.

               (xi) The  Company  and each of the  Subsidiaries  are  insured by
          insurers of recognized  financial  responsibility  against such losses
          and risks and in such  amounts as are  prudent  and  customary  in the
          business in which they are engaged; and neither the Company nor any of
          the Subsidiaries has any reason to believe that it will not be able to
          renew  its  existing  insurance  coverage  as and when  such  coverage
          expires or to obtain similar  coverage from similar insurers as may be
          necessary to continue its business at a cost that would not materially
          and  adversely  affect the  business  or  financial  condition  of the
          Company and the Subsidiaries taken as a whole,  except as described or
          contemplated in the Prospectus.

               (xii) Ernst & Young LLP,  which has  examined and  expressed  its
          opinion on certain of the  financial  statements  of the Company filed
          with the Commission as a part of the Registration  Statement,  are, to
          the Company's best knowledge,  independent accountants with respect to
          the  Company  within  the  meaning  of  the  Act  and  the  Rules  and
          Regulations;  the  financial  statements,  together  with the  related
          notes,  forming  part of the  Registration  Statement  and  Prospectus
          fairly present the financial  condition of the Company and its results
          of  operations  as of the dates and for the periods  described in such
          opinion in the  Prospectus;  and such financial  statements  have been
          prepared in accordance with the requirements of the Commission.

               (xiii) The Company and each of the Subsidiaries maintain a system
          of  internal  accounting  controls  sufficient  to provide  reasonable
          assurances   that   transactions   are  executed  in  accordance  with
          management's  general or specific  authorizations  and are recorded as
          necessary to permit preparation of financial  statements in conformity
          with generally accepted accounting principles.

               (xiv) Except as stated in the Prospectus, the Company knows of no
          outstanding  claims for  services,  either in the nature of a finder's
          fee or origination fee, with respect to the transactions  contemplated
          hereby  and the  Related  Transactions,  and  the  Company  agrees  to
          indemnify and hold the  Underwriters  harmless from any such claim for
          any such  services of such nature  arising  from the act of any person
          other than any Underwriter.

               (xv) Except for the Selling Stockholders, no person holds a right
          to require or  participate  in the  registration  under the Act of the
          Common  Stock  of the  Company  to be  effected  by  the  Registration
          Statement,  which right has not been effectively  waived by the holder
          thereof as of the date hereof.

               (xvi)  The  Company  has  obtained  from  each  of its  officers,
          directors  and  holders  of 1% or more of the shares of, or options to
          purchase shares of, the Company's  Common Stock an executed  agreement
          that, except as otherwise specifically altered in such agreement, they
          will  not,  without  the  prior  written  consent  of Allen &  Company
          Incorporated  on behalf  of the  Underwriters,  sell,  offer for sale,
          contract to sell or otherwise  dispose of any shares of the  Company's
          Common Stock or any securities exercisable for or convertible into its
          Common  Stock  for a period  of [240]  days from the date of the final
          Prospectus, subject to certain exceptions.

          (b) Each Selling  Stockholder,  jointly and severally,  represents and
     warrants to, and agrees with, each Underwriter and the Company that:

               (i) All consents, approvals, authorizations, and orders necessary
          for the  execution  and delivery by such Selling  Stockholder  of this
          Agreement and the Jamison Contribution Agreement, and for the sale and
          delivery  of  the  Stockholder  Shares  to be  sold  by  such  Selling
          Stockholder  hereunder  (other than, at the time of execution  hereof,
          (if the Registration  Statement has not yet been declared effective by
          the Commission) the issuance of the order of the Commission  declaring
          the  Registration   Statement   effective  and  such   authorizations,
          approvals or consents as may be necessary from the NASD or under state
          or other securities or Blue Sky laws) have been obtained. Such Selling
          Stockholder  has full right,  power and  authority  to enter into this
          Agreement and the Jamison Contribution  Agreement and to sell, assign,
          transfer,  and  deliver  the  Stockholder  Shares  to be  sold by such
          Selling  Stockholder  hereunder  and to  consummate  the  transactions
          contemplated by the Jamison Contribution Agreement. This Agreement and
          the  Jamison  Contribution  Agreement  have  been  duly  executed  and
          delivered  by such  Selling  Stockholder  and are  valid  and  binding
          agreements,  enforceable  in accordance  with their terms,  except (1)
          that  such  enforcement  may be  subject  to  bankruptcy,  insolvency,
          reorganization,  moratorium  or other similar laws now or hereafter in
          effect relating to creditors'  rights, (2) that the remedy of specific
          performance and injunctive and other forms of equitable  relief may be
          subject  to  equitable  defenses  and to the  discretion  of the court
          before which any proceeding  therefor may be brought and (3) as rights
          to indemnity or  contribution  hereunder  may be limited by federal or
          state securities laws.

               (ii)  Neither the sale of  Stockholder  Shares to be sold by such
          Selling  Stockholder  hereunder,  nor  the  execution,  delivery,  and
          performance  of this Agreement or the Jamison  Contribution  Agreement
          will result in a breach or violation of any material term or provision
          of, or constitute a default under, any currently existing material and
          relevant statute,  any material  indenture,  mortgage,  deed of trust,
          loan or

                                      -7-

<PAGE>

          note  agreement,  or other  material  agreement or instrument to which
          such  Selling  Stockholder  is  a  party  or  by  which  such  Selling
          Stockholder is bound,  or any order,  rule, or regulation of any court
          or governmental  agency or body having  jurisdiction over such Selling
          Stockholder or over any of such Selling Stockholder's properties.

               (iii)   Immediately  prior  to  the  Closing  Date  such  Selling
          Stockholder  will have,  valid and marketable title to the Stockholder
          Shares  to be sold by such  Selling  Stockholder  hereunder,  free and
          clear of all liens,  encumbrances,  equities,  and claims  (other than
          pursuant  to  this  Agreement  and   restrictions   under   applicable
          securities law). Upon delivery of such Stockholder  Shares and payment
          therefor   pursuant  hereto,   valid  and  marketable  title  to  such
          Stockholder  Shares,  free  and  clear  of  all  liens,  encumbrances,
          equities, and claims, will pass to the Underwriters.

               (iv)  Such  Selling  Stockholder  has not taken and will not take
          (directly or indirectly)  any action which is designed to or which has
          constituted  or might  reasonably  be  expected  to cause or result in
          stabilization  or  manipulation  of the price of any  security  of the
          Company in order to facilitate the sale or resale of the Shares.

               (v) Any statement or omission in the Registration Statement,  the
          Prospectus, or any post-effective amendment or supplement thereto that
          is or was  made  in  reliance  upon  and in  conformity  with  written
          information  furnished  to the  Company  by such  Selling  Stockholder
          expressly  for use  therein  is  true,  complete  and  correct  in all
          material  respects  and does not  contain  any untrue  statement  of a
          material fact or omit to state any material fact required to be stated
          therein  or  necessary  to  make  such  statements,  in  light  of the
          circumstances under which they were made, not misleading.

               (vi) Nothing has come to such Selling Stockholder's  attention to
          cause it to have reason to believe that the Company's  representations
          and warranties contained in this Agreement or the Jamison Contribution
          Agreement are not accurate in any material respect.

               (vii)  Such   Selling   Stockholder   has   carefully   read  the
          Registration  Statement,  the  Prospectus,  and this Agreement and the
          Jamison  Contribution  Agreement  and that to its best  knowledge  its
          representations,  warranties,  and other statements  contained in this
          Agreement and the Jamison  Contribution  Agreement are accurate in all
          material  respects  on the date  hereof  and will be  accurate  in all
          material  respects on and as of the First  Closing Date (as defined in
          Section 3 hereof) with the same effect as if made on the First Closing
          Date,  and  such  Selling   Stockholder   has  performed  all  of  its
          obligations  and satisfied all  conditions on its part to be performed
          or satisfied at or prior to the First Closing Date.

     3.   PURCHASE,   SALE  AND  DELIVERY  OF  SHARES.   On  the  basis  of  the
representations,  warranties and agreements herein contained, but subject to the
terms and  conditions  herein set forth,  (i) the Company agrees to sell to each
Underwriter and each

                                      -8-

Underwriter agrees, severally and not jointly, to purchase from the Company at a
purchase price of $______ [INSERT PRICE AFTER UNDERWRITERS' FEES] per Share, the
aggregate  number  of  Company  Shares  set  forth  opposite  the  name  of such
Underwriter in Schedule A hereto under the column "Company  Shares" and (ii) the
Selling  Stockholders  agree to sell to each  Underwriter,  and each Underwriter
agrees,  severally and not jointly, to purchase from the Selling Stockholders at
a purchase price of $____________  [INSERT PRICE AFTER  UNDERWRITERS'  FEES] per
Share, the aggregate number of Stockholder Shares set forth opposite the name of
such Underwriter in Schedule A hereto under the column "Stockholder Shares."

     The Company will deliver the Company Shares,  and the Selling  Stockholders
will  deliver the  Stockholder  Shares,  to you for the  accounts of the several
Underwriters  at the office of Allen & Company  Incorporated,  711 Fifth Avenue,
New York, New York,  against payment of the purchase price therefor by certified
or official  bank check or checks in New York Clearing  House funds,  payable to
the order of  Realty  Information  Group,  Inc.,  and the  order of the  Selling
Stockholders listed on Schedule C hereto, respectively,  at 10:00 A.M., New York
Time,  on  ____________________,  1998, or at such other time and date not later
than five full  business days  thereafter as you and the Company may  determine,
such time and date of  delivery  and  payment  being  herein  called  the "First
Closing Date".  The  certificates for the Shares to be so delivered will be made
available  to you at such  office for  checking at least one full  business  day
prior to such  Closing Date and will be in such names and  denominations  as you
may request not less than two full business days prior to such Closing Date.

     On the  basis of the  representations,  warranties  and  agreements  herein
contained, but subject to the terms and conditions herein set forth, the Company
grants to the  Underwriters an option to purchase up to [270,000]  Option Shares
at the same price per share as the Underwriters shall pay for the Company Shares
and  the  Stockholder  Shares.  Such  option  may be  exercised  only  to  cover
over-allotments  arising in  connection  with the sale of Company  Shares by the
Underwriters,  such  exercise  to be upon  written  notice by you to the Company
within 45 days of the date hereof  setting  forth the number of Option Shares as
to which the Underwriters are exercising the option, the denominations and names
in which  certificates  for such Shares  should be  registered  and the time and
place at which  such  certificates  are to be  delivered.  Such  time and  place
(unless such time is the First Closing Date),  herein referred to as the "Second
Closing  Date",  shall be  determined  by you but shall not be earlier  than the
First Closing Date,  nor earlier than three full business days or later than ten
full business  days after the exercise of such option.  The Company will deliver
Option  Shares  to you for the  accounts  of the  several  Underwriters  against
payment of the purchase  price  therefor by certified or official  bank check or
checks in New York Clearing House funds payable to the order of the Company. The
number of Option Shares to be purchased by each Underwriter shall be in the same
proportion to the aggregate  number of Option Shares  purchased as the number of
Company Shares plus the number of Stockholder Shares set forth opposite the name
of such Underwriter in Schedule A hereto bears to [2,700,000].

     It is understood that you,  individually and not as the  Representatives of
the several  Underwriters,  may (but shall not be obligated  to) make payment on
behalf of any Underwriter


                                      -9-

or Underwriters  for Shares to be purchased by such Underwriter or Underwriters.
Any such payment by you shall not relieve any such  Underwriter or  Underwriters
of any of its or their obligations hereunder.

     After  the   Registration   Statement   becomes   effective,   the  several
Underwriters  propose  to offer  the  Shares  to the  public as set forth in the
Prospectus.

     4.  COVENANTS OF THE  COMPANY.  The Company  covenants  and agrees with the
several Underwriters that:

          (a) The Company  will use its best  efforts to cause the  Registration
     Statement  and any  subsequent  amendment  thereto to become  effective  as
     promptly as possible;  it will notify you,  promptly after it shall receive
     notice  thereof,  of  the  time  when  the  Registration  Statement  or any
     subsequent amendment to the Registration  Statement has become effective or
     any  supplement  to the  Prospectus  has been  filed;  it will  notify  you
     promptly of any request by the Commission for the amending or supplementing
     of the Registration Statement or Prospectus or for additional  information;
     it will prepare and file with the  Commission,  promptly upon your request,
     any amendments or supplements to the  Registration  Statement or Prospectus
     which,  in your  reasonable  opinion,  may be  necessary  or  advisable  in
     connection with the distribution of the Shares by the Underwriters; it will
     promptly  prepare and file with the Commission,  and promptly notify you of
     the filing of, any amendments or supplements to the Registration  Statement
     or  Prospectus  which  may  be  necessary  to  correct  any  statements  or
     omissions,  if, at any time when a  prospectus  relating  to the  Shares is
     required to be delivered  under the Act, any event shall have occurred as a
     result of which the  Prospectus  or any other  prospectus  relating  to the
     Shares as then in effect  would  include an untrue  statement of a material
     fact or omit to state any material  fact  necessary to make the  statements
     therein not  misleading;  in case any  Underwriter is required to deliver a
     prospectus  after the nine-month  period referred to in Section 10(a)(3) of
     the Act in connection  with sales of the Shares,  it will prepare  promptly
     upon request,  but at the expense of such  Underwriter,  such  amendment or
     amendments  to  the   Registration   Statement   and  such   prospectus  or
     prospectuses as may be necessary to permit compliance with the requirements
     of Section 10(a)(3) of the Act; and it will file no amendment or supplement
     to the Registration  Statement or Prospectus that shall not previously have
     been  submitted to you in writing a  reasonable  time prior to the proposed
     filing  thereof with an opportunity to review and comment on such amendment
     or supplement.

          (b) The  Company  will  advise you,  promptly  after it shall  receive
     notice or obtain  knowledge  thereof,  of the issuance by the Commission of
     any stop order suspending the  effectiveness of the Registration  Statement
     or of any order suspending  trading in the Shares or other of the Company's
     securities  or of the  initiation  or  threat  of any  proceeding  for that
     purpose;  and it will use promptly its best efforts to prevent the issuance
     of any stop order or to obtain its  withdrawal  if such a stop order should
     be issued.

          (c) The  Company  will use its best  efforts to qualify the Shares for
     sale under the blue sky or securities laws of such jurisdictions as you may
     reasonably designate and

                                      -10-

<PAGE>


     to continue  such  qualifications  in effect for so long as may be required
     for  purposes of the  distribution  of the Shares,  except that the Company
     shall not be required in connection  therewith or as a condition thereof to
     qualify as a foreign corporation or to execute a general consent to service
     of process in any state.

          (d) The Company will furnish to you, as soon as  available,  copies of
     the  Registration  Statement (at least two of which will be signed and will
     include all exhibits), each Preliminary Prospectus, the Prospectus, and any
     amendments or  supplements  to such  documents,  including  any  prospectus
     prepared to permit compliance with Section 10(a)(3) of the Act, all in such
     quantities as you may from time to time reasonably request.

          (e) The Company will make generally  available to its  securityholders
     as soon as practicable,  a financial statement (which will be in reasonable
     detail but need not be audited)  covering a 12-month period beginning after
     the effective date of the  Registration  Statement  which shall satisfy the
     provisions of Section 11(a) of the Act.

          (f) The Company  agrees,  during each fiscal year for a period of five
     years from the date hereof,  to furnish to its  stockholders as promptly as
     may be practicable an annual report (including financial statements audited
     by  independent  public  accountants)  and to furnish  quarterly  financial
     statements  (which  need not be  audited  and  which  may be  condensed  or
     summarized)  for each of the first  three  quarters  of each  fiscal  year,
     statements  of  operations  and surplus of the Company for such  quarter in
     reasonable  detail and  certified by the Company's  principal  financial or
     accounting  officer, or the Company's quarterly report on Form 10-Q; (i) as
     soon as practicable after the end of each fiscal year, financial statements
     of the Company as at the end of such fiscal year,  including  statements of
     operations,  retained  earnings  and changes in  financial  position of the
     Company for such fiscal year, all in reasonable detail and accompanied by a
     copy  of the  report  thereon  of  independent  public  accountants  or the
     Company's  annual  report  on Form  10-K;  and  (ii)  as  soon as they  are
     available,  copies of all reports and financial  statements furnished to or
     filed  with  the  Commission.  During  such  period,  if and so long as the
     Company shall have active subsidiaries,  the foregoing financial statements
     shall  be on a  combined  or  consolidated  basis  to the  extent  that the
     accounts of the Company and its subsidiaries are combined or consolidated.

          (g) The Company  covenants  and agrees  with the several  Underwriters
     that the Company will pay or cause to be paid the following:  (i) the fees,
     disbursements,  and expenses of the Company's  counsel and  accountants  in
     connection  with the  registration  of the Shares  under the Act;  (ii) all
     other expenses in connection with the preparation,  printing, and filing of
     the Registration Statement, each Preliminary Prospectus, and the Prospectus
     and amendments and supplements  thereto,  and the mailing and delivering of
     copies thereof to the Underwriters and dealers;  (iii) the cost of printing
     or duplicating this Agreement,  the Selected Dealer Agreement, the Blue Sky
     Memorandum,  and any  other  documents  in  connection  with the  offering,
     purchase,  sale and delivery of the Shares;  (iv) all costs and expenses in
     connection  with the issuance  and delivery of the Shares  hereunder to the
     Underwriters, including related transfer taxes, if any; (v) all expenses in
     connection with the qualification of the Shares for offering and


                                      -11-
<PAGE>


     sale under the  securities  laws of various  jurisdictions,  including  the
     reasonable  fees and  disbursements  of  counsel  for the  Underwriters  in
     connection  with such  qualification  and in  connection  with the Blue Sky
     Survey;  (vi) the filing fees  incident to securing any required  review by
     the National  Association of Securities  Dealers,  Inc. of the terms of the
     sale of the Shares; (vii) the costs of preparing stock certificates; (viii)
     the cost and charges of any transfer agent or registrar; and (ix) all other
     costs and  expenses  of the  Company  incident  to the  performance  of its
     obligations hereunder which are not otherwise  specifically provided for in
     this Section 4. The Company shall reimburse the Underwriters,  upon request
     from time to time, for their reasonable itemized  out-of-pocket expenses up
     to a maximum of $________, including their legal fees and disbursements and
     travel,   roadshow  and  syndicate  expenses,   upon  the  presentation  of
     reasonable  documentation  thereof.  If  the  Underwriters  are  unable  or
     unwilling  to proceed  with the  offering on the terms and  conditions  set
     forth in this  Agreement for any reason (except as set forth in the proviso
     below),  the  Underwriters  shall  bear  all  of  their  own  out-of-pocket
     expenses,  including legal fees and disbursements and travel,  roadshow and
     syndicate expenses;  provided,  however, that if the Underwriters' decision
     not to proceed with the offering on the terms and  conditions  set forth in
     this  Agreement  is based  upon any of the  reasons  specified  in  Section
     10(b)(i), (excluding termination for reasons that are beyond the reasonable
     control of the  Company)  the Company  shall be required to  reimburse  the
     Underwriters for their out-of-pocket expenses as specified in the preceding
     sentence.

          (h) The Company  agrees  that it will not,  for a period of [240] days
     after the date of the final  Prospectus,  without the prior written consent
     of Allen & Company Incorporated on behalf of the Underwriters,  sell, offer
     for sale, contract to sell or otherwise dispose of any shares of its Common
     Stock or any securities  exercisable for or convertible  into shares of its
     Common  Stock,  other  than  (i)  shares  issuable  pursuant  to  currently
     outstanding  rights,  options  and  warrants,  (ii) the grant of options or
     shares under the Company's  [Stock  Purchase and Option Plan];  or (iii) in
     connection with the acquisition of work,  products or businesses,  provided
     that in the case of this clause (iii) none of such shares shall be publicly
     realizable during such [240] day period, subject to certain exceptions.  In
     addition,  the Company also agrees to obtain the written  agreement of each
     officer,  director and holder of 1% or more of the shares of, or options to
     purchase shares of, the Company's Common Stock (including,  but not limited
     to, the Selling Stockholders) that such person will not, without such prior
     written  consent,  sell,  offer for  sale,  contract  to sell or  otherwise
     dispose of any of such Common Stock or any  securities  exercisable  for or
     convertible  into  Common  Stock held by such  holder for a period of [240]
     days after the date of the final  Prospectus,  except as may  otherwise  be
     specifically  allowed in the agreements  referenced in paragraph  2(a)(xvi)
     above.

     5. CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the several
Underwriters to purchase and pay for the Company Shares and  Stockholder  Shares
on the First Closing Date and the Option  Shares on the Second  Closing Date, as
provided herein shall be subject to the accuracy, as of the date hereof and such
Closing Date (as if made on and as of such Closing Date), of the representations
and  warranties  of the  Company  and the Selling  Stockholders  herein,  to the
performance  by the Company and the Selling  Stockholders  of their  obligations
hereunder, and to the following additional conditions:

                                      -12-
<PAGE>


          (a) The  Registration  Statement shall have become effective not later
     than 5:30 P.M., New York City Time, on the date of this Agreement,  or such
     later date as shall be  consented  to in writing by you; if  required,  the
     Prospectus  and any amendment or  supplement  thereto shall have been filed
     with the  Commission  in the manner and within the time period  required by
     Rule 424(b) under the Act; and no stop order  suspending the  effectiveness
     thereof  shall have been issued and no  proceedings  for that purpose shall
     have been initiated or, to the knowledge of the Company or any Underwriter,
     threatened  by the  Commission,  and  any  request  of the  Commission  for
     additional information (to be included in the Registration Statement or the
     Prospectus   or   otherwise)   shall  have  been   complied  with  to  your
     satisfaction.

          (b)  Prior  to  such  Closing  Date,  except  as  contemplated  in the
     Prospectus, there shall not have been any change in the capital shares, nor
     the issuance of any material rights,  options,  or warrants to purchase any
     capital shares, nor any material increase or decrease in any long-term debt
     of the Company or any of the Subsidiaries or any material adverse change in
     the condition (financial or otherwise), results of operations,  business or
     prospects  of  the  Company  or  any  of the  Subsidiaries  which  in  your
     reasonable judgment renders it inadvisable to proceed with the offering and
     sale of the Shares.

          (c) You shall have received the opinion of Wilmer, Cutler & Pickering,
     counsel for the  Company,  in form and  substance  satisfactory  to you and
     dated such Closing Date, to the effect that:

               (i) each of the Company,  its Subsidiaries,  RIGINC and RIGLP has
          been duly  incorporated  or  organized  and is validly  existing  as a
          corporation  or  limited  partnership,  as the  case  may be,  in good
          standing under the laws of its jurisdiction of incorporation with full
          corporate power and authority to own its properties and to conduct its
          business  as  described  in the  Registration  Statement  and is  duly
          qualified  to  do  business  as  a  foreign   corporation  or  limited
          partnership,  as the case may be, in each state or jurisdiction  where
          its  operations  and the  ownership of its  properties  requires  such
          qualification,  except  with  respect  to  qualification  as a foreign
          corporation  or  limited  partnership,  as the  case  may be,  in such
          jurisdictions  in which the failure to so qualify has not had and will
          not have a material  adverse effect on the business of the Company and
          the Subsidiaries taken as a whole;

               (ii) the Company has authorized capital stock as set forth in the
          Prospectus;  all shares of Common Stock, including the Shares, conform
          as to  legal  matters  in all  material  respects  to the  appropriate
          descriptions  thereof under the heading "Description of Capital Stock"
          in the  Prospectus;  all  outstanding  shares of Company capital stock
          have been duly  authorized  and are  validly  issued,  fully  paid and
          non-assessable;   and  the  issuance  of  the  Shares  has  been  duly
          authorized  and,  when issued and  delivered in  accordance  with this
          Agreement,   the  Shares  will  be  validly  issued,  fully  paid  and
          non-assessable;  and,  except  as  described  in the  Prospectus,  the
          issuance of the Shares as described in the Prospectus  will not result
          in any adjustment of the exercise  price or number of shares  issuable
          upon exercise in respect of any outstanding options or warrants


                                      -13-

          of the Company; and, except as otherwise set forth in the Registration
          Statement,  the  Company  owns  (directly  or  indirectly)  all of the
          respective  outstanding  shares  of  capital  stock  of  each  of  the
          Subsidiaries,  free and clear of any material  liens,  encumbrances or
          claims;

               (iii) each of this Agreement,  the RIG Contribution Agreement and
          the Jamison Contribution Agreement has been duly authorized,  executed
          and delivered by the Company,  RIGINC and RIGLP,  as  applicable,  and
          constitutes a valid and binding agreement of the Company,  enforceable
          in accordance with its terms,  except that (1) such enforcement may be
          subject to bankruptcy, insolvency, reorganization, moratorium or other
          similar laws now or hereafter in effect relating to creditors' rights,
          (2) the remedy of specific  performance and injunctive and other forms
          of equitable  relief may be subject to  equitable  defenses and to the
          discretion  of the court before which any  proceeding  therefor may be
          brought, and (3) rights to indemnity or contribution  hereunder may be
          limited by federal or state  securities  laws;  the sale of the Shares
          under this Agreement and the consummation of the  transactions  herein
          contemplated and the Related Transactions do not result in a breach or
          violation  of any  terms or  provisions  of, or  constitute  a default
          under, any presently  existing  statute,  or any indenture,  mortgage,
          deed of trust,  note  agreement or other  agreement or  instrument  to
          which the Company,  RIGINC or RIGLP,  as applicable,  is a party or by
          which it or its properties  are bound or affected,  or to which any of
          the material  property or assets of the Company,  RIGINC or RIGLP,  as
          applicable,  or the Subsidiaries is subject, the Company's or RIGINC's
          certificate  of  incorporation  or  by-laws,   RIGLP's  organizational
          documents,   or  any  order,  rule  or  regulation  of  any  court  or
          governmental  agency or body  having  jurisdiction  over the  Company,
          RIGINC, RIGLP or the Subsidiaries or over their respective properties;

               (iv) no consent, approval, authorization or order of any court or
          governmental  agency or body is required for the  consummation  by the
          Company,  RIGINC  and  RIGLP,  as  applicable,   of  the  transactions
          contemplated  by this  Agreement or the Related  Transactions,  except
          such as may be  required  under  the Act or as may be  required  under
          state  securities or blue sky laws in connection with the purchase and
          distribution of the Shares by the Underwriters;

               (v) the Registration Statement has become effective under the Act
          and no stop order  suspending the  effectiveness  of the  Registration
          Statement  has been issued and no  proceedings  for that  purpose have
          been instituted or are pending or contemplated under the Act;

               (vi)  except as stated in the  Prospectus,  the  Company  and the
          Subsidiaries  hold all  material  licenses,  permits,  authorizations,

          standing, of Federal,  State or local, and foreign governmental bodies
          necessary to carry on their respective  businesses as reflected in the
          Registration  Statement,  except  where the  failure  to hold any such
          license, permit,

                                      -14-

<PAGE>


          authorization,  franchise, consent or order, would not have a material
          adverse  effect on the business or  operations  of the Company and the
          Subsidiaries, taken as a whole;

               (vii) the  agreements or documents to which the Company,  RIGINC,
          RIGLP or the  Subsidiaries  are a party which are summarized under the
          headings "Management - Employment Agreements," "Certain Transactions,"
          "Description   of   Capital   Stock   -   Registration   Rights"   and
          "_____________"  in the Prospectus conform in all material respects to
          such summaries;

               (viii) there are no legal or governmental  proceedings pending or
          threatened to which the Company  RIGINC,  RIGLP or any Subsidiary is a
          party or to which any properties of the Company,  RIGINC, RIGLP or the
          Subsidiaries  are subject  which is required  to be  described  in the
          Registration Statement or the Prospectus and is not so described;

               (ix) the  Registration  Statement  and the  Prospectus,  and each
          amendment or supplement thereto,  as of their respective  effective or
          issue  dates,  comply  as to form in all  material  respects  with the
          requirements  of the Act and the Rules and  Regulations  (except  that
          such counsel need express no opinion as to the  financial  statements,
          notes to financial statements, related schedules or other financial or
          statistical  data  contained  in  the  Registration  Statement  or the
          Prospectus);

               (x)  all  contracts  and  documents  pertaining  to the  Company,
          RIGINC,  RIGLP  required to be filed as  Exhibits to the  Registration
          Statement  have been  filed as  required  or have  been  appropriately
          incorporated by reference and all contracts and documents  required to
          be described in the Prospectus have been accurately  described therein
          in all material respects;

               (xi) Such counsel  shall also state that it has  participated  in
          conferences  with officers and other  representatives  of the Company,
          representatives  of the independent public accountants for the Company
          and the representatives of the Underwriters,  at which the contents of
          the Registration Statement and the Prospectus and related matters were
          discussed and,  although such counsel is not passing upon and does not
          assume any responsibility  for the accuracy,  completeness or fairness
          of the  statements  contained in the  Registration  Statement  and the
          Prospectus,  on the basis of the foregoing  (relying as to materiality
          to  a  large   extent  upon  the   opinions  of  officers   and  other
          representatives of the Company),  no facts have come to such counsel's
          attention  which lead such  counsel to believe  that the  Registration
          Statement  (except  with  respect  to  the  financial  statements  and
          schedules thereto and other financial or statistical data, as to which
          such counsel

                                      -15-
<PAGE>


          need not make any statement) at the time it became effective or at the
          Closing Date  contained  any untrue  statement  of a material  fact or
          omitted  to state a material  fact  required  to be stated  therein or
          necessary to make the statements  therein not misleading,  or that the
          Prospectus  (except  with  respect  to the  financial  statements  and
          schedules thereto and other financial or other statistical data, as to
          which such counsel need not make any statement) on the date thereof or
          on the Closing Date contained any untrue  statement of a material fact
          or  omitted to state a material  fact  necessary  in order to make the
          statements  therein,  in the light of the  circumstances in which they
          were made, not misleading.

     In rendering  the foregoing  opinions,  such counsel may rely as to factual
matters on  certificates of officers and  representatives  of the Company or any
Subsidiary and of public  officials,  and will not be required to  independently
verify the accuracy or completeness of information or documents  furnished to it
in respect to the Registration  Statement or the Prospectus.  To the extent that
such counsel's opinion relates to the laws of jurisdictions other than Delaware,
such  counsel  shall  be  permitted  to rely on the  opinion  of  local  counsel
reasonably satisfactory to counsel for the several Underwriters.

          (d) You shall have received from[Cushing,  Morris, Armbruster & Jones,
     LLP], counsel to the Selling Stockholders,  an opinion,  dated such Closing
     Date,  in form and  substance  satisfactory  to you,  with respect to legal

     and the transactions  contemplated hereby and thereby as you may reasonably
     require.

     transactions  contemplated  hereby as you may reasonably  require,  and the
     Company  shall have  furnished to such  counsel such  documents as they may
     have requested for the purpose of enabling them to pass upon such matters.

          (f)  You  shall  have  received,  at the  time  of  execution  of this
     Agreement  and on such  Closing  Date from Ernst & Young  LLP,  independent
     public  accountants,  a letter  or  letters,  dated  the  date of  delivery
     thereof,  substantially  in the form and substance  heretofore  approved by
     you.

          (g) You shall have received a certificate, dated such Closing Date, of
     each of the President and Chief  Executive  Officer and the Chief Financial
     Officer of the Company,  delivered on behalf of the Company,  to the effect
     that:

          Date;  and the  Company  has  complied  with all such  agreements  and
          satisfied all the  conditions on its part to be performed or satisfied

          purpose have been instituted or, to their knowledge,  are contemplated
          by the Commission; and

<PAGE>


               (iii)  except  as  contemplated  in the  Prospectus,  none of the
          Company,  RIGINC,  RIGLP or any  Subsidiary has incurred any direct or
          contingent  material  liabilities or obligations since the date of the
          finance statements included in the Prospectus,  other than liabilities
          incurred  in the  ordinary  course of  business,  or entered  into any
          material  transactions  or  contracts  not in the  ordinary  course of
          business,  and there has not been any  material  change in its capital
          shares,  nor the  issuance  of any  rights,  options,  or  warrants to

     Contribution  Agreement  are true and  correct as if made on and as of such
     Closing Date; and the such Selling  Stockholder  has complied with all such
     agreements  and satisfied all the conditions on its part to be performed or
     satisfied at or prior to such Closing Date;

          (i) The Company and the Selling  Stockholders  shall have furnished to
     you such certificates,  in addition to those specifically mentioned herein,
     as you may have reasonably  requested,  as to the accuracy and completeness
     at such Closing  Date of any  statement  in the  Registration  Statement or
     Prospectus,  as to the accuracy at such Closing Date of the representations
     and warranties of the Company herein,  as to the performance by the Company
     of its obligations  hereunder,  and as to the fulfillment of the conditions
     concurrent and precedent to the obligations of the Underwriters hereunder.

          (j) The Company shall have furnished to you the  agreements  described
     in Section 2(a)(xvi) of this Agreement.

     6. INDEMNIFICATION. (a) The Company and the Selling Stockholders, severally
and not jointly,  will  indemnify and hold harmless  each  Underwriter  and each
person,  if any,  who controls  any  Underwriter  within the meaning of the Act,
against any losses, claims,  damages or liabilities,  joint or several, to which
such Underwriter or such controlling person may become subject, under the Act 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 the  Registration  Statement,
any  Preliminary  Prospectus,  the  Prospectus,  or any  amendment or supplement
thereto,  or arise out of or are based upon the omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not misleading,  and will reimburse each Underwriter and
each such controlling person for any legal or other expenses reasonably incurred
by such Underwriter or such controlling  person in connection with investigating
or  defending  against  any such  loss,  claim,  damage,  liability  or  action;
provided, however, that neither the Company nor the Selling Stockholders will be
liable in any such  case to the  extent  that any such  loss,  claim,  damage or
liability arises out of or is based upon any

                                      -17-
<PAGE>


untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in the Registration Statement, such Preliminary Prospectus,  the Prospectus
or such  amendment or such  supplement in reliance  upon and in conformity  with
written  information  furnished  to the Company by any  Underwriter  through you
specifically for use therein; and provided further, that the foregoing indemnity
with respect to Preliminary  Prospectuses  shall not inure to the benefit of any
Underwriter (or to the benefit of any person  controlling  such  Underwriter) if
such untrue  statement or omission or alleged untrue  statement or omission made
in any Preliminary  Prospectus is eliminated or remedied in the Prospectus and a
copy of the Prospectus  has not been furnished to the person  asserting any such
losses, claims,  damages, or liabilities at or prior to the written confirmation
of the  sale of such  Shares  to such  person;  and  provided  further,  that no
indemnification  pursuant to this  Section 6(a) shall be sought from the Selling
Stockholders   unless  the  Company  shall,  after  reasonable  efforts  by  the
Underwriters to secure  indemnification from the Company, have failed to satisfy
its  indemnification  obligations under this Section 6(a), and in no event shall
the liability of any Selling Stockholder under this Section 6(a), if any, exceed
the gross proceeds (minus the amount of the underwriting  discount paid thereon)
received by such Selling  Stockholders  from the sale of his Stockholder  Shares
pursuant to this Agreement. Such indemnity obligation will be in addition to any
liability which the Company and the Selling Stockholders may otherwise have. The
indemnity  agreement  of the Company and the Selling  Stockholders  contained in
this paragraph (a) and the representations and warranties of the Company and the
Selling Stockholders contained in Section 2 hereof shall remain operative and in
full force and effect  regardless of any  investigation  made by or on behalf of
any  indemnified  party and shall  survive  the  delivery of and payment for the
Shares.

          (b) Each  Underwriter,  severally and not jointly,  will indemnify and
     hold harmless the Company, each of its directors,  each of its officers who
     signed the Registration  Statement,  and each person,  if any, who controls
     the Company  within the  meaning of the Act and the  Selling  Stockholders,
     against any losses,  claims,  damages or liabilities,  joint or several, to
     which the Company or any such director,  officer or controlling  person, or
     the Selling  Stockholders  may become subject,  under the Act 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 the Registration
     Statement, any Preliminary Prospectus,  the Prospectus, or any amendment or
     supplement  thereto,  or arise out of or are  based  upon the  omission  or
     alleged  omission to state  therein a material  fact  required to be stated
     therein or necessary to make the statements therein not misleading, in each
     case to the extent,  but only to the extent,  that such untrue statement or
     alleged  untrue  statement  or  omission  or alleged  omission  was made in
     reliance upon and in conformity with written  information  furnished to the
     Company by any Underwriter  through you specifically  for use therein;  and
     will  reimburse  any legal or other  expenses  reasonably  incurred  by the
     Company or any such director, officer or controlling person, or the Selling
     Stockholders in connection with investigating or defending against any such
     loss, claim, damage, liability or action. Such indemnity obligation will be
     in addition to any liability which such Underwriter may otherwise have. The
     indemnity  agreement of each  Underwriter  contained in this  paragraph (b)
     shall  remain  operative  and in full  force and effect  regardless  of any
     investigation made by

                                      -18-
<PAGE>

          or on behalf of any  indemnified  party and shall survive the delivery
          of and payment for the Shares.

          (c) Promptly after receipt by an indemnified  party under this Section
     of notice of the commencement of any action,  such indemnified  party will,
     if a claim in respect thereof is to be made against the indemnifying  party
     under this  Section,  notify  the  indemnifying  party of the  commencement
     thereof. Indemnification shall not be available to any party who shall fail
     so to give notice, if the party to whom notice was required to be given was
     unaware of the action, suit, investigation,  inquiry or proceeding to which
     the notice would have related, to the extent that such party was prejudiced
     by  the  failure  to  give  notice;  but  the  omission  so to  notify  the
     indemnifying party will not relieve it from any liability which it may have
     to any  indemnified  party  otherwise than under this Section.  In case any
     such action is brought against any indemnified  party,  and it notifies the
     indemnifying party of the commencement thereof, the indemnifying party will
     be  entitled  to  participate  therein  and, to the extent that it may wish
     jointly with any other indemnifying party similarly notified, to assume the
     defense thereof,  with counsel chosen by such  indemnifying  party which is
     reasonably  satisfactory to such  indemnified  party, and after notice from
     the  indemnifying  party to such  indemnified  party of its  election so to
     assume the defense thereof,  the  indemnifying  party will not be liable to
     such  indemnified  party under this Section for any legal or other expenses
     subsequently  incurred by such  indemnified  party in  connection  with the
     defense thereof other than  reasonable  costs of  investigation;  provided,
     however, that (i) if the indemnified party reasonably determines that there
     may be a conflict  between the positions of the  indemnifying  party and of
     the  indemnified  party in  conducting  the defense of such  action,  suit,
     investigation,  inquiry or  proceeding,  then  counsel for the  indemnified
     party shall be  entitled  to conduct  the defense to the extent  reasonably
     determined  by such counsel to be necessary to protect the interests of the
     indemnified  party and (ii) in any event,  the  indemnified  party shall be
     entitled to have counsel chosen by such indemnified  party  participate in,
     but not conduct,  the defense at the sole expense of the indemnified party.
     No indemnifying  party shall be liable to any indemnified  party in respect
     to any settlement effected without its prior written consent, which consent
     shall not be unreasonably  withheld.  In addition,  the indemnifying  party
     will not, without the prior written consent of an indemnified party, settle
     or  compromise  or consent to the entry of any  judgment  in any pending or
     threatened  claim,   action,   suit  or  proceeding  in  respect  of  which
     indemnification  may be sought  hereunder  if such  indemnified  party is a
     party to such claim, action or suit or proceeding), unless such settlement,
     compromise or consent includes an unconditional release of such indemnified
     party  from  all  liability  arising  out of such  claim,  action,  suit or
     proceeding.

     7.  CONTRIBUTION.  In order to provide for contribution in circumstances in
which the indemnification provided for in Section 6(a) or 6(b) hereof is for any
reason,  other than the first proviso to Section 6(a),  held to be  unavailable,
the Company,  the Selling  Stockholders and the Underwriters shall contribute to
the aggregate losses, claims, damages and liabilities of the nature contemplated
by such indemnification provisions (including any investigation, legal and other
expenses  incurred in connection  with,  any amount paid in  settlement  of, any
action,  suit or  proceeding  or any claims  asserted,  but after  deducting any
contribution  received by the Company and the Selling  Stockholders from persons
other than the


                                      -19-
<PAGE>


Underwriters,  such as persons who  control  the  Company  within the meaning of
Section 15 of the Act,  officers  of the  Company  who  signed the  Registration
Statement and directors of the Company, who may also be liable for contribution)
to  which  the  Company,  the  Selling  Stockholders  and  one  or  more  of the
Underwriters  may be subject,  in such  proportions so that the Underwriters are
responsible for that portion in each case represented by the percentage that the
respective  underwriting discounts appearing on the cover page of the Prospectus
bear to the public offering price of the Shares, and the Company and the Selling
Stockholders are responsible for the remaining portion in such proportion as the
Shares  offered by the Company and the  Selling  Stockholders  bear to the total
number of Shares;  provided,  however, that (i) except as may be provided in its
Master Agreement Among Underwriters provided to Allen & Company Incorporated, in
no case shall any  Underwriter  be  responsible  for any amount in excess of the
underwriting  discount  applicable to the Shares  purchased by such  Underwriter
hereunder and (ii) the liability of each Selling  Stockholder under this Section
7, if any,  shall  not  exceed  the  gross  proceeds  (minus  the  amount of the
underwriting  discount paid thereon)  received by such Selling  Stockholder from
the sale of his  Stockholder  Shares  pursuant to this  Agreement,  and (iii) no
person  guilty of  fraudulent  misrepresentation  (within the meaning of Section
11(f) of the Act) shall be entitled to contribution  from any person who was not
guilty of such  fraudulent  misrepresentation.  For  purposes of this Section 7,
each person,  if any, who controls an Underwriter  within the meaning of Section
15 of the Act shall have the same rights to  contribution  as such  Underwriter,
and each person,  if any, who controls the Company within the meaning of Section
15 of  the  Act,  each  officer  of  the  Company  who  shall  have  signed  the
Registration  Statement  and each  director of the  Company  shall have the same
right to  contribution  as the Company,  subject in each case to clauses (i) and
(ii) of this Section 7. Any party entitled to contribution will,  promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim for  contribution  may be made against another
party or parties  under this  Section 7, notify such party or parties  from whom
contribution may be sought,  but the omission to so notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any other  obligation it or they may have hereunder or otherwise than under this
Section 7. No party shall be liable for contribution  with respect to any action
or claim settled  without its consent,  which consent shall not be  unreasonably
withheld.

     8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. All representations,
warranties  and  agreements  of the Company,  the Selling  Stockholders  and the
Underwriters  herein or in certificates  delivered  pursuant hereto shall remain
operative and in full force and effect regardless of any  investigation  made by
or on behalf of any Underwriter or any controlling  person, the Company,  or any
of its officers,  directors, or controlling persons or the Selling Stockholders,
and shall survive delivery of the Shares to the several Underwriters hereunder.

     9. SUBSTITUTION OF UNDERWRITERS.  If any Underwriter or Underwriters  shall
fail  to  take up and pay for the  number  of  Shares  to be  purchased  by such
Underwriter or  Underwriters  hereunder upon tender of such Shares in accordance
with the  terms  hereof,  and if the  aggregate  number  of  Shares  which  such
defaulting Underwriter or Underwriters so agreed

                                      -20-

<PAGE>


but  failed  to  purchase  does not  exceed  10% of the  Shares,  the  remaining
Underwriters  shall be obligated  severally in  proportion  to their  respective
commitments  hereunder  to take up and pay  for the  Shares  of such  defaulting
Underwriter or Underwriters.  If one or more of the  Underwriters  shall fail or
refuse (other than for a reason  sufficient to justify the  termination  of this
Agreement) to purchase on any Closing Date the aggregate number of Shares agreed
to be purchased by such  Underwriter or Underwriters and the aggregate number of
Shares agreed to be purchased by such  Underwriter or Underwriters  shall exceed
10% of the aggregate  number of Shares to be sold on any Closing Date  hereunder
by the Company and the Selling Stockholders to the Underwriters,  then the other
Underwriters  shall  have the right to  purchase  or  procure  one or more other
underwriters  to purchase,  in such  proportions as they may agree upon and upon
the terms herein set forth,  the Shares  which such  defaulting  Underwriter  or
Underwriters  agreed  to  purchase,  and this  Agreement  shall be  carried  out
accordingly.  If such other  Underwriters  do not  exercise  such  right  within
thirty-six  hours after receiving  notice of any such default,  which notice the
Representatives  shall have also  promptly  delivered to the  Company,  then the
Company  shall have the right to  procure  another  party or parties  reasonably
satisfactory to the Representatives to purchase or agree to purchase such Shares
on the terms herein set forth.  If the Company is unable to procure another such
party,  the  Company  may notify  the  Representatives  that the  non-defaulting
Underwriters are, by the giving of such notice,  released from their obligations
to purchase  such number of Shares  being sold  hereunder by the Company and the
Selling  Stockholders  as are indicated in such notice as, when  subtracted from
the total  number  of Shares  originally  agreed to be  purchased  by all of the
Underwriters  hereunder,  shall leave a reduced number of Shares to be purchased
by the non-defaulting Underwriters not in excess of 110% of the aggregate number
of Shares originally  contracted to be purchased hereunder by the non-defaulting
Underwriters,  and each of them, in which event such non-defaulting Underwriters
shall  purchase  such  reduced  number of Shares.  In any such case,  either the
Representatives or the Company shall have the right to postpone any Closing Date
for a period  of not more  than  seven  business  days in order  that  necessary
changes and arrangements may be effected by the Representatives and the Company.
If  neither  the   non-defaulting   Underwriters  nor  the  Company  shall  make
arrangements  within the period stated for the purchase of the Shares which such
defaulting  Underwriter  or  Underwriters  agreed to  purchase,  including  such
arrangements  for the purchase of a reduced number of Shares as are provided for
in this Section 9, then this Agreement shall terminate  without liability on the
part  of  any  non-defaulting   Underwriters  to  the  Company  or  the  Selling
Stockholders  and  without  liability  on the part of the Company or the Selling
Stockholders to the Underwriters.

     In the event of any termination of this Agreement pursuant to the preceding
paragraph  of this  Section,  neither the  Company nor the Selling  Stockholders
shall be under any liability to any  Underwriter  (except as provided in Section
4(g) and 6 hereof)  nor shall any  Underwriter  (other than an  Underwriter  who
shall  have  failed,  otherwise  than  for  some  reason  permitted  under  this
Agreement,  to purchase the number of Shares to be purchased by such Underwriter
hereunder,  which  Underwriter  shall remain liable to the Company,  the Selling
Stockholders and the other Underwriters for damages resulting from such default)
be under any  liability  to the Company or the Selling  Stockholders  (except as
provided in Section 6 hereof).

     specified  at any time at or prior to the First  Closing Date if (i) either
     the Company or the Selling Stockholders shall have failed,  refused or been
     unable,  at or prior to the First  Closing  Date,  to perform any  material
     agreement  on its part to be  performed,  or  because  any  other  material
     condition  of  the  Underwriters'  obligations  hereunder  required  to  be
     fulfilled  by the Company is not  fulfilled;  (ii)  trading on the New York
     Stock Exchange shall have been suspended,  or minimum or maximum prices for

     Stock  Exchange  or by order of the  Commission  or any other  governmental
     authority having jurisdiction, since the execution of this Agreement; (iii)
     a banking  moratorium  shall  have been  declared  by  Federal  or New York
     authorities  since the execution of this Agreement;  or (iv) an outbreak of
     major hostilities or other national calamity shall have occurred.  Any such
     termination  shall be without  liability  on the part of the Company or the
     Selling  Stockholders  to  any  Underwriter  or of any  Underwriter  to the
     Company or the Selling Stockholders other than as provided in Sections 4(g)
     and 6 hereof.

          (b) If you elect to prevent this Agreement from becoming  effective or
     to terminate  this  Agreement as provided in this Section,  the Company and
     the Selling  Stockholders shall be notified promptly by you by telephone or
     telegram,  confirmed by letter.  If the Company shall elect to prevent this
     Agreement from becoming  effective,  you shall be notified  promptly by the
     Company by telephone or telegram, confirmed by letter.

Dear Sirs:

     1.  PURCHASE  OF  SECURITIES  BY  THE  SEVERAL  UNDERWRITERS.  The  several
Underwriters named in the enclosed Prospectus,  on whose behalf we are acting as
Representatives,  have  severally  agreed to purchase  from  Realty  Information
Group, Inc. (the "Company") and the stockholders of Jamison Research,  Inc. (the
"Selling  Stockholders")  an offering  of  [2,700,000]  Shares of the  Company's
Common Stock (the  "Shares"),  as set forth in the Prospectus and subject to the
terms of the  Underwriting  Agreement  between  the  several  Underwriters,  the
Company  and  the  Selling  Stockholders.   The  Shares  are  described  in  the
Prospectus, additional copies of which will be supplied in reasonable quantities
upon request to us.

     2. OFFERING TO SELECTED  DEALERS.  One or more of the several  Underwriters
acting  through  us are  severally  offering  a portion of the Shares to certain
dealers ("Selected Dealers") as principals,  subject to the terms and conditions
of their purchase,  to the terms and conditions  hereof, and to the modification
or cancellation of the offering without notice, at the public offering price set
forth in the  Prospectus,  less a  concession  not in excess of $____ per Share.
Shares  purchased  by the  several  Underwriters,  and not sold to the  Selected
Dealers  as  aforesaid,  may be sold  by the  several  Underwriters.  Any of the
several Underwriters may be included among the Selected Dealers.

     The offering of a portion of the Shares to Selected  Dealers may be made on
the basis of reservations or allotments  against  subscription.  We are advising
you by  telegram  of the method  and terms of the  offering.  Acceptance  of any
reserved  Shares  received by us at the office of Allen & Company  Incorporated,
711 Fifth Avenue, New York, New York 10022, after the time specified therefor in
the telegrams,  and any subscriptions for additional Shares,  will be subject to
prior  sale and  allotment.  Subscription  books may be closed by us at any time
without notice,  and the right is reserved to reject any  subscriptions in whole
or in part.

     3.   OFFERING  TO  PUBLIC  BY  SELECTED   DEALERS.   Upon  receipt  of  the
aforementioned telegram, the Shares purchased by you hereunder may be re-offered
to the  public  in  conformity  with the  terms  of  offering  set  forth in the
Prospectus. You may, in accordance with the rules of the National Association of
Securities  Dealers,  Inc., reallow a concession of $_____ per Share sold by you
to any other  dealer or broker who is a member of the  National  Association  of
Securities Dealers, Inc., provided such discount is retained.


<PAGE>


     Neither you nor any other person is or has been  authorized by the Company,
any  of  the  several  Underwriters  or us  to  give  information  or  make  any
representations  in  connection  with the sale of the  Shares  other  than those
contained in the Prospectus.

     In the event that during the term of this agreement we, as  Representatives
for the  account of the  several  Underwriters,  shall  purchase  or contract to
purchase,  at or below  the  original  public  offering  price  set forth in the
Prospectus,  any  of  the  Shares  purchased  by  you  hereunder  (which  Shares
theretofore were not effectively  placed for investment by you, including Shares
represented  by transfers),  we may, at our election,  either (a) require you to
repurchase  such  Shares  at a price  equal  to the  total  cost of such  Shares
purchased by us, including brokerage commissions,  if any, and transfer taxes on
the  redelivery,  or (b) charge you with and collect from you an amount equal to
the selling concession with respect to the Shares so purchased by us.

     4.  PAYMENT AND  DELIVERY.  Payment for the Shares which you have agreed to
purchase  hereunder shall be made by you on _________,  1998, or such later date
as we may  advise  you,  at 9:00  a.m.,  New  York  Time,  at  Allen  &  Company
Incorporated's  office  at 711  Fifth  Avenue,  New  York,  New York  10022,  by
certified or bank  cashier's  check payable in New York Clearing  House funds to
the order of Allen & Company  Incorporated,  against  delivery  of such  Shares.
Delivery  instructions  must be in our hands at said  address at such time as we
request.

     Additional Shares confirmed to you shall be delivered on such date or dates
as we shall advise you.

     5. BLUE SKY MATTERS.  Neither we nor any of the several  Underwriters shall
have any obligation or responsibility with respect to the right of any dealer to
sell the Shares in any jurisdiction,  notwithstanding  any information which may
be furnished as to the states under the securities  laws of which it is believed
the Shares may be sold.

     6. TERMINATION. This agreement shall terminate 20 full days after the First
Closing Date (as defined in the Underwriting  Agreement) but may be extended for
a period or periods not exceeding in the aggregate 20 days as we may  determine.
We  may   terminate   this   Agreement  at  any  time  without   prior   notice.
Notwithstanding  the termination of this agreement,  you shall remain liable for
your  portion of any transfer  tax or other  liability  which may be asserted or
assessed  against us or any one or more of the several  Underwriters or Selected
Dealers based upon the claim that the Selected Dealers or any of them constitute
a partnership,  an  association,  an  unincorporated  business or other separate
entity.

     7. OBLIGATIONS OF SELECTED DEALERS.  Your acceptance hereof will constitute
an obligation on your part to purchase,  upon the terms and  conditions  hereof,
the  aggregate  amount of the Shares  reserved  for and  accepted  by you and to
perform and observe all the terms and conditions hereof.

     You are not authorized to act as agent for any of the several  Underwriters
in offering Shares to the public or otherwise.  Nothing  contained  herein shall
constitute  the Selected  Dealers an  association,  or partners with the several
Underwriters, with us, or with each other.

                  SECTION 4. Notice of Meetings.  Written notice of each meeting
of the  stockholders  shall be given not less than ten (10) nor more than  sixty
(60) days before the date of the meeting to each  stockholder of the Corporation
entitled to vote at such  meeting.  The notice  shall state the place,  date and
time of the  meeting  and,  in the case of a special  meeting,  the  purpose  or
purposes for which the meeting is called.

                  SECTION 5.  Quorum.  At any meeting of the  stockholders,  the
holders of a majority in number of the total  issued and  outstanding  shares of
stock of the Corporation entitled to vote at such meeting,  present in person or
represented  by proxy,  shall  constitute a quorum of the  stockholders  for all
purposes,  unless  the  representation  of a larger  number of  shares  shall be
required by law, by the  Certificate of  Incorporation  or by these By-Laws,  in
which  case the  representation  of the  number  of  shares  so  required  shall
constitute a quorum.

                  SECTION 6. Adjourned  Meetings.  Whether or not a quorum shall
be present in person or  represented  at any  meeting of the  stockholders,  the
holders  of a  majority  in  number of the  shares  of stock of the  Corporation
present in person or  represented  by proxy and entitled to vote at such meeting
may adjourn  from time to time.  When a meeting is  adjourned to another time or
place,  notice need not be given of the adjourned  meeting if the time and place
thereof are announced at the meeting at which the  adjournment is taken.  At the
adjourned  meeting the  stockholders  may transact any business which might have
been transacted by them at the original meeting.  If the adjournment is for more
than thirty days, or if after the adjournment a new record date is fixed for the
adjourned  meeting,  a notice of the  adjourned  meeting  shall be given to each
stockholder of record entitled to vote at the adjourned meeting.

                  SECTION  7.  Voting.  Except  as  otherwise  provided  in  the
Certificate of Incorporation  or by law, each  stockholder  shall be entitled to
one vote for each share of the capital  stock of the  Corporation  registered in
the name of such stockholder upon the books of the Corporation. Each stockholder
entitled to vote at a meeting of  stockholders  or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons  to act for him or her by  proxy,  but no such  proxy  shall be voted or
acted upon after  three  years from its date,  unless the proxy  provides  for a
longer period. When a quorum is present at a meeting of the stockholders, except
as otherwise  provided by law or by the Certificate of Incorporation,  Directors
shall be elected by a plurality  of the votes cast at a meeting of  stockholders
by the stockholders entitled to vote in the election and, whenever any corporate
action,  other  than the  election  of  Directors  is to be  taken,  it shall be
authorized by a majority of the votes cast at a meeting of  stockholders  by the
stockholders entitled to vote thereon.

                  Shares of the capital  stock of the  Corporation  belonging to
the Corporation or to another corporation,  if a majority of the shares entitled
to vote in the election of directors of such other corporation is held, directly
or  indirectly,  by the  Corporation,  shall  neither be entitled to vote nor be
counted for quorum purposes.

Corporation,  including any proposal relating to the nomination of a Director to
be elected to the Board of Directors of the Corporation,  the stockholders  must
have given timely notice thereof in writing to the Secretary of the Corporation.
To be timely, a stockholder's  notice shall be delivered to the Secretary at the
principal  executive  offices of the  Corporation not less than 60 days nor more
than 90 days  prior to the first  anniversary  of the  preceding  year's  annual
meeting;  provided,  however,  that in the event that the annual  meeting is the
first annual  meeting of the  Corporation  or the date of the annual  meeting is
advanced  by more  than  30  days or  delayed  by  more  than 60 days  from  the
anniversary  date  of  the  preceding  year's  annual  meeting,  notice  by  the
stockholder  to be timely must be so  delivered  not  earlier  than the 90th day
prior to such  annual  meeting  and not later than the close of  business on the
later of the 60th day prior to such  annual  meeting or the tenth day  following
the day on which public  announcement of the date of such meeting is first made.
Such  stockholder's  notice  shall  set  forth  (a) as to each  person  whom the
stockholder  proposes to nominate for election or  reelection  as a director all
information  relating  to  such  person  that is  required  to be  disclosed  in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities  Exchange Act of 1934,
as amended;  (b) as to any other business that the stockholder proposes to bring
before the meeting,  a brief  description of the business  desired to be brought
before the meeting,  the reasons for conducting such business at the meeting and
any material interest in such business of such stockholder and of the beneficial
owner,  if  any,  on  whose  behalf  the  proposal  is  made;  and (c) as to the
stockholder  giving the notice and the beneficial owner, if any, on whose behalf
the  nomination  or  proposal  is  made,  (i)  the  name  and  address  of  such
stockholder,  as they appear on the Corporation's  books, and of such beneficial
owner and (ii) the class and number of shares of stock of the Corporation  which
are owned  beneficially  and of record by such  stockholder  and such beneficial
owner. The Chairman of an annual meeting shall, if the facts warrant,  determine
and declare to an annual meeting that a proposal was not properly brought before
such meeting in  accordance  with this  Section,  and if the Chairman  should so
determine,  the Chairman should so declare to such meeting and any such business
not properly brought before the meeting shall not be transacted.

                  SECTION  9.  Organization.   The  Chairman  of  the  Board  of
Directors or, in the absence of the Chairman of the Board,  the President  shall
call all  meetings  of the  stockholders  to  order,  and shall  preside  at all
meetings of the  stockholders.  In the absence of the  Chairman of the Board and
the President, the holders of a majority in number of the shares of stock of the
Corporation  present in person or  represented  by proxy and entitled to vote at
such meeting shall elect a presiding officer for purposes of such meeting.

                  The Secretary of the Corporation shall act as Secretary of all
meetings of the stockholders; but in the absence of the Secretary, the presiding
officer may appoint any person to act as secretary of the meeting.

                                    Directors

                  SECTION 1. Powers. The business and affairs of the Corporation
shall be managed by or under the  direction of a Board of  Directors,  which may

things  as are not by law or by the  Certificate  of  Incorporation  or by these
By-Laws directed or required to be exercised or done by the stockholders.

respective   successors  are  elected  and  qualified  or  until  their  earlier
resignation or removal.

                  (b)  Unless by the  terms of the  action  pursuant  to which a
director is elected any special  condition  or  conditions  must be fulfilled in
order for such director to be qualified, a person elected as a director shall be
deemed to be qualified (1) upon such person's  receipt of notice of election and
such person's indication of acceptance thereof or (2) upon the expiration of ten
days after notice of election is given to such person without such person having
given notice of inability or unwillingness to serve.

                  SECTION 3. Removal,  Vacancies and Additional  Directors.  The
stockholders may, at any special meeting the notice of which shall state that it
is called  for that  purpose,  remove,  with or  without  cause,  any  Director.
Vacancies  caused by any such  removal , or any  vacancy  caused by the death or
resignation  of any  Director  or for any other  reason,  and any newly  created
directorship  resulting from any increase in the authorized number of Directors,
may be filled by the  affirmative  vote of a majority of the  Directors  then in
office, even if less than a quorum, and any Director so elected to fill any such
vacancy or newly created  directorship  shall hold office until his successor is
elected and qualified or until his earlier resignation or removal.

                  When one or more Directors shall resign  effective at a future
date, a majority of the Directors  then in office,  including  those who have so
resigned,  shall have power to fill such vacancy or vacancies,  the vote thereon
to take effect when such resignation or resignations shall become effective, and
each Director so chosen shall hold office as herein  provided in connection with
the filling of other vacancies.

regular meeting of the Board of Directors; but a copy of every resolution fixing
or  changing  the time or place of  regular  meetings  shall be  mailed to every
Director at least five days before the first meeting held in pursuance  thereof,
or caused to be transmitted by telegraph,  cable or wireless at least three days
before the first meeting held in pursuance thereof.

                  SECTION 6. Special Meetings.  Special meetings of the Board of
Directors may be called by direction of the Chairman of the Board, the President

                  Notice of the day,  hour and place of holding of each  special
meeting  shall be given by mailing the same at least two days before the meeting
or by causing  the same to be  transmitted  by  telegraph,  cable or wireless at
least one day before the meeting to each Director. Unless otherwise indicated in
the  notice  thereof,  any and all  business  other than an  amendment  of these
By-Laws may be  transacted  at any special  meeting,  and an  amendment of these
By-Laws  may be acted upon if the notice of the  meeting  shall have stated that
the  amendment of these  By-Laws is one of the  purposes of the meeting.  At any
meeting at which  every  Director  shall be  present,  even  though  without any

Directors in office shall  constitute a quorum for the  transaction  of business
and the vote of the  majority  of the  Directors  present at any  meeting of the
Board of Directors at which a quorum is present shall be the act of the Board of
Directors. If at any meeting of the Board there is less than a quorum present, a
majority of those  present may  adjourn the meeting  from time to time,  without
notice  other  than  announcement  at the  meeting,  until a quorum is  present,
whereupon the meeting may be held, as adjourned, without further notice.

                  SECTION  8.  Organization.  The  Chairman  of the Board  shall
preside  at all  meetings  of the  Board of  Directors.  In the  absence  of the
Chairman of the Board,  an acting  Chairman  shall be elected from the Directors

as  Secretary  of all  meetings  of the  Directors;  but in the  absence  of the
Secretary,  the  Chairman  may  appoint  any person to act as  Secretary  of the
meeting.

                  SECTION  9.  Committees.   The  Board  of  Directors  may,  by
resolution  passed by a  majority  of the  whole  Board,  designate  one or more
committees,  each  committee  to consist of one or more of the  Directors of the
Corporation.  The Board may designate one or more Directors as alternate members
of any  committee,  who may  replace  any absent or  disqualified  member at any
meeting of the committee.  In the absence or  disqualification  of a member of a
committee,  the  member  or  members  thereof  present  at any  meeting  and not
disqualified  from voting,  whether or not he or they  constitute a quorum,  may
unanimously  appoint  another  member  of the Board of  Directors  to act at the
meeting  in the  place of any  such  absent  or  disqualified  member.  Any such
committee,

<PAGE>



to the extent  provided by  resolution  passed by a majority of the whole Board,
shall  have and may  exercise  all the  powers  and  authority  of the  Board of
Directors in the management of the business and the affairs of the  Corporation,
and may authorize the seal of the  Corporation to be affixed to all papers which
may  require  it; but no such  committee  shall have the power or  authority  in
reference to amending the Certificate of Incorporation, adopting an agreement of
merger or  consolidation,  recommending to the  stockholders  the sale, lease or
exchange of all or substantially all of the  Corporation's  property and assets,
recommending  to  the  stockholders  a  dissolution  of  the  Corporation  or  a
revocation  of a  dissolution,  or  amending  these  By-Laws;  and  unless  such
resolution,  these By-laws,  or the  Certificate of  Incorporation  expressly so
provide,  no such  committee  shall  have the power or  authority  to  declare a
dividend or to authorize the issuance of stock.

                  Each  committee  shall  determine  its rules  with  respect to
notice, quorum, voting and the taking of action,  provided that such rules shall
be consistent  with law, the rules in these  By-Laws  applicable to the Board of
Directors  and  the  resolution  of the  Board  of  Directors  establishing  the
committee.  Each committee shall keep regular minutes of its meetings and report
the same to the Board of Directors when required.

                  SECTION 10. Conference  Telephone  Meetings.  Unless otherwise
restricted by the Certificate of Incorporation or by these By-Laws,  the members
of the  Board  of  Directors  or any  committee  designated  by the  Board,  may
participate in a meeting of the Board or such committee,  as the case may be, by
means of conference  telephone or similar  communications  equipment by means of
which all persons  participating  in the  meeting can hear each other,  and such
participation shall constitute presence in person at such meeting.

                  SECTION  11.  Consent of  Directors  or  Committee  in Lieu of
Meeting.  Unless otherwise  restricted by the Certificate of Incorporation or by
these  By-Laws,  any action  required or permitted to be taken at any meeting of
the Board of  Directors,  or of any  committee  thereof,  may be taken without a
meeting if all members of the Board or  committee,  as the case may be,  consent
thereto in writing  and the  writing or  writings  are filed with the minutes of
proceedings of the Board or committee, as the case may be.


                                   ARTICLE IV

first meeting after each annual meeting of the stockholders, the officers of the
Corporation,  which  shall  include a Chairman of the Board,  a Chief  Executive
Officer, a Chief Financial Officer, a President,  one or more Vice Presidents, a
Secretary and a Treasurer. The failure to hold such election shall not of itself
terminate  the term of office of any officer.  The Board of Directors  may elect
such  additional  officers it deems desirable for the conduct of the business of
the Corporation pursuant to the provisions of Section 10 of this Article IV. All
officers shall hold office at the pleasure of the Board

his or her earlier resignation or removal and all officers, agents and employees
shall be subject to removal,  with or without cause, at any time by the Board of
Directors. The removal of an officer without cause shall be without prejudice to
his contract rights,  if any but the election or appointment of an officer shall
not of itself  create  contract  rights.  All  agents and  employees  other than
officers  elected by the Board of  Directors  shall also be subject to  removal,
with or without cause, at any time by the officers  appointing them. Any vacancy
caused by the death, resignation or removal of any officer, or otherwise, may be
filled by the Board of Directors.

these By-Laws or by the Board of Directors.  All actions heretofore taken by the
Chairman of the Board in the name or on behalf of the Corporation, including the

business and affairs,  and shall have all powers and perform all duties incident
to the office of  President.  In the absence of the  Chairman of the Board,  the

                                    ARTICLE V

                    Indemnification of Directors and Officers

                  SECTION 1. Rights to Indemnification; Advancement of Expenses.
To the fullest extent  required or permitted by applicable  law, the Corporation
shall  indemnify  any person who was or is a party or is threatened to be made a
party to any  threatened,  pending  or  completed  action,  suit or  proceeding,
whether civil, criminal,  administrative or investigative, by reason of the fact
that such  person is or was or has agreed to become a Director or officer of the
Corporation,  or is or was  serving or has agreed to serve at the request of the
Corporation as a Director or officer of another corporation,  partnership, joint
venture,  trust or other enterprise,  or by reason of any action alleged to have
been taken or omitted in such capacity,  and may indemnify any person who was or
is a  party  or is  threatened  to be made a party  to such an  action,  suit or
proceeding  by reason  of the fact that he is or was or has  agreed to become an
employee  or agent of the  Corporation,  or is or was  serving  or has agreed to
serve at the  request  of the  Corporation  as an  employee  or agent of another
corporation,  partnership,  joint venture,  trust or other  enterprise,  against
expenses  (including  attorneys'  fees),  judgments,  fines and amounts  paid in
settlement  actually  and  reasonably  incurred  by such person or on his or her
behalf in  connection  with  such  action,  suit or  proceeding  and any  appeal
therefrom,  if  such  person  acted  in good  faith  and in a  manner  he or she
reasonably believed to be in or not


                                        9

<PAGE>



opposed to the best  interests  of the  Corporation,  and,  with  respect to any
criminal  action or  proceeding,  had no reasonable  cause to believe his or her
conduct was unlawful;  except that in the case of an action or suit by or in the
right  of  the  Corporation  to  procure  a  Judgment  in  its  favor  (l)  such
indemnification  shall  be  limited  to  expenses  (including  attorneys'  fees)
actually and reasonably  incurred by such person in the defense or settlement of
such action or suit, and (2) no indemnification  shall be made in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to the Corporation  unless and only to the extent that the Delaware Court
of  Chancery  or the  court in which  such  action  or suit  was  brought  shall
determine upon  application  that,  despite the adjudication of liability but in
view of all the  circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses  which the Delaware Court of Chancery or
such other court shall deem proper.

                  SECTION 2. Successful  Defense. To the extent that a Director,
officer,  employee or agent of the Corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in Section
1 of this Article V or in defense of any claim,  issue or matter  therein,  such
person  shall  be  indemnified  against  expenses  (including  attorneys'  fees)
actually and reasonably incurred by him or her in connection therewith.

                  SECTION 3. Determination  that  Indemnification is Proper. Any
indemnification  of a Director or officer,  employee or agent of the Corporation
under  Section 1 of this Article V (unless  ordered by a court) shall be made by
the  Corporation  unless a  determination  is made that  indemnification  of the
Director or officer is not proper in the circumstances because he or she has not
met the  applicable  standard  of  conduct  set  forth  in  Section  1. Any such
determination  shall be made (1) by the Board of Directors by a majority vote of
a quorum  consisting of Directors  who were not parties to such action,  suit or
proceeding, or (2) if such a quorum its not obtainable, or, even if obtainable a
quorum of disinterested  Directors so directs, by independent legal counsel in a
written opinion, or (3) by the vote of a majority of the stockholders present or
voting by proxy at an annual or special meeting of the stockholders.

                  SECTION 4. Advance  Payment of  Expenses.  Unless the Board of
Directors  otherwise  determines  in a specific  case,  expenses  incurred  by a
Director or officer in defending a civil or criminal action,  suit or proceeding
shall be paid by the  Corporation  in advance of the final  disposition  of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of the
Director or officer to repay such amount if it shall  ultimately  be  determined
that  he or  she  is not  entitled  to be  indemnified  by  the  Corporation  as
authorized  in this Article V. Such  expenses  incurred by other  employees  and
agents may be so paid upon such terms and  conditions,  if any,  as the Board of
Directors  deems   appropriate.   The  Board  of  Directors  may  authorize  the
Corporation's  legal counsel to represent  such Director,  officer,  employee or
agent in any action,  suit or  proceeding,  whether or not the  Corporation is a
party to such action, suit or proceeding.

                  SECTION  5.  Survival:   Preservation  of  Other  Rights.  The
foregoing  indemnification  provisions  shall be deemed to be a contract between
the Corporation and each Director, officer, employee and agent who serves in any
such capacity at any time while these provisions as well as


                                       10

<PAGE>



the relevant  provisions of the Delaware  General  Corporation Law are in effect
and any repeal or modification  thereof shall not affect any right or obligation
then existing with respect to any state of facts then or previously  existing or
any action,  suit, or proceeding  previously or thereafter brought or threatened
based in whole or in part upon any such state of facts.  Such a  contract  right
may not be modified retroactively without the consent of such Director, officer,
employee or agent.

        The  indemnification  provided  by this  Article  V shall  not be deemed
exclusive of any other rights to which those  indemnified  may be entitled under
statute, any by-law,  agreement, vote of stockholders or disinterested Directors
or  otherwise,  both as to action in his  official  capacity and as to action in
another  capacity  while holding such office,  and shall continue as to a person
who has ceased to be a Director,  officer,  employee or agent and shall inure to
the benefit of the heirs,  executors and  administrators  of such a person.  The
corporation  may enter into an agreement  with any of its  Directors,  officers,
employees or agents providing for  indemnification  and advancement of expenses,
including attorneys fees, that may change,  enhance,  qualify or limit any right
to indemnification or advancement of expenses created by this Article V.

                  SECTION  6.  Severability.  If this  Article V or any  portion
hereof  shall  be   invalidated   on  any  ground  by  any  court  of  competent
jurisdiction, then the Corporation shall nevertheless indemnify each Director or
officer and may indemnify each employee or agent of the Corporation as to costs,
charges and expenses (including  attorneys' fees),  judgment,  fines and amounts
paid in  settlement  with  respect to any action,  suit or  proceeding,  whether
civil, criminal,  administrative or investigative,  including an action by or in
the right of the Corporation,  to the fullest extent permitted by any applicable
portion  of this  Article  V that  shall not have  been  invalidated  and to the
fullest extent permitted by applicable law.

                  SECTION   7.   Subrogation.   In  the  event  of   payment  of
indemnification  to a person  described  in  Section  1 of this  Article  V, the
Corporation  shall be  subrogated  to the extent of such payment to any right of
recovery  such  person may have and such  person,  as a condition  of  receiving
indemnification  from the  Corporation,  shall  execute all documents and do all
things that the  Corporation  may deem  necessary  or  desirable to perfect such
right of recovery, including the execution of such documents necessary to enable
the Corporation effectively to enforce any such recovery.

                  SECTION 8. No Duplication of Payments.  The Corporation  shall
not be liable  under this Article V to make any payment in  connection  with any
claim made  against a person  described  in  Section 1 of this  Article V to the
extent such person has otherwise  received payment (under any insurance  policy,
by-law or otherwise) of the amounts otherwise indemnifiable hereunder.

                                   ARTICLE VI

                                  Capital Stock

                  SECTION 1.  Certificates For Shares of Stock. The certificates
for shares of stock of the Corporation  shall be in such form, not  inconsistent
with the  Certificate  of  Incorporation,  as shall be  approved by the Board of
Directors.  All  certificates  shall be signed by the Chairman of the Board, the
Chief Executive  Officer,  the President,  the Chief Financial Officer or a Vice
President and by the Secretary or an Assistant  Secretary or the Treasurer or an
Assistant Treasurer, and shall not be valid unless so signed.

                  In case any officer or officers who shall have signed any such
certificate  or  certificates  shall cease to be such officer or officers of the
Corporation,  whether  because of death,  resignation or otherwise,  before such
certificate or certificates  shall have been delivered by the Corporation,  such
certificate or certificates  may nevertheless be issued and delivered as through
the person or persons who signed such certificate or certificates had not ceased
to be such officer or officers of the corporation.

                  All  certificates  for shares of stock shall be  consecutively
numbered  as the same are  issued.  The name of the  person  owning  the  shares
represented thereby with the number of such shares and the date of issue thereof
shall be entered on the books of the corporation.

                  Except as hereinafter provided,  all certificates  surrendered
to the Corporation for transfer shall be canceled, and no new certificates shall
be issued  until  former  certificates  for the same  number of shares have been
surrendered and canceled.

                  SECTION 2. Lost, Stolen or Destroyed Certificates.  Whenever a
person owning a certificate for shares of stock of the Corporation  alleges that
it has been lost,  stolen or destroyed,  such person shall file in the office of
the  Corporation  an  affidavit  setting  forth,  to the  best of such  person's
knowledge and belief,  the time,  place and  circumstances of the loss, theft or
destruction,  and, if required by the Board of Directors, a bond of indemnity or
other  indemnification  sufficient  in the opinion of the Board of  Directors to
indemnify  the  Corporation  and its agents  against  any claim that may be made
against it or them on account of the alleged loss,  theft or  destruction of any
such  certificate or the issuance of a new certificate in replacement  therefor.
Thereupon  the  Corporation  may  cause  to  be  issued  to  such  person  a new
certificate in replacement for the certificate alleged to have been lost, stolen
or destroyed.  Upon the stub of every new  certificate  so issued shall be noted
the fact of such issue and the number, date and the name of the registered owner
of the  lost,  stolen  or  destroyed  certificate  in  lieu  of  which  the  new
certificate is issued.

                  SECTION  3.  Transfer  of  Shares.  Shares  of  stock  of  the
Corporation  shall be transferred on the books of the  Corporation by the holder
thereof, in person or by his attorney duly authorized in writing, upon surrender
and  cancellation  of  certificates  for the  number  of  shares  of stock to be
transferred, except as provided in Section 2 of this Article.

                  SECTION  4.  Dividends.  Subject  to  the  provisions  of  the
Certificate of Incorporation, the Board of Directors shall have power to declare
and pay dividends upon shares of stock of the Corporation, but only out of funds
available for the payment of dividends as provided by law.

                  Subject to the provisions of the Certificate of Incorporation,
any  dividends  declared upon the stock of the  Corporation  shall be payable on
such date or dates as the Board of Directors shall determine.  If the date fixed
for the  payment of any  dividend  shall in any year fall upon a legal  holiday,
then the dividend payable on such date shall be paid on the next day not a legal
holiday.


                                   ARTICLE VII

                                     Notices

                  SECTION 1.  General.  Whenever,  under the  provisions  of the
statutes or of the Certificate of Incorporation  or of these By-Laws,  notice is
required to be given to any director or  stockholder,  it shall not be construed
to mean  personal  notice,  but such  notice may be given in  writing,  by mail,
addressed to such director or  stockholder,  at his or her address as it appears
on the records of the corporation, with postage thereon prepaid, and such notice
shall be deemed to be given at the time when the same shall be  deposited in the
United  States  mail.  Notice  to  directors  may also be given by  telegram  or
telephone.

                  SECTION 2. Waiver. Whenever any notice whatever is required to
be given by law, by the Certificate of  Incorporation or by these By-Laws to any
person or persons, a waiver thereof in writing,  signed by the person or persons
entitled to the notice,  whether before or after the time stated therein,  shall
be deemed equivalent thereto.


                                  ARTICLE VIII

                  SECTION 1. Checks,  Notes, Etc. All checks,  drafts,  bills of
exchange,  acceptances,  notes or other obligations or orders for the payment of
money  shall  be  signed  and,  if  so  required  by  the  Board  of  Directors,
countersigned  by such officers of the  Corporation  and/or other persons as the
Board of Directors from time to time shall designate.

                  Checks,  drafts,  bills  of  exchange,   acceptances,   notes,
obligations  and orders for the payment of money made payable to the Corporation
may be  endorsed  for  deposit  to the  credit  of the  Corporation  with a duly
authorized  depository by the Treasurer and/or such other officers or persons as
the Board of Directors from time to time may designate.

Directors. When authorized to do so, any officer or agent of the Corporation may
effect loans and advances for the  Corporation  from any bank,  trust company or
other  institution or from any firm,  corporation  or  individual,  and for such
loans and  advances may make,  execute and deliver  promissory  notes,  bonds or
other evidences of indebtedness  of the  Corporation.  When authorized so to do,
any officer or agent of the Corporation may pledge,  hypothecate or transfer, as
security  for the  payment  of any and all  loans,  advances,  indebtedness  and
liabilities  of the  corporation,  any  and all  stocks,  securities  and  other
personal  property  at any  time  held by the  Corporation,  and to that end may
endorse,  assign and deliver the same. Such authority may be general or confined
to specific instances.

                  SECTION 3.  Contracts.  Except as otherwise  provided in these
By-Laws  or by law or as  otherwise  directed  by the  Board of  Directors,  the
Chairman of the Board,  the Chief Executive  Officer,  the President,  the Chief
Financial  Officer or any Vice  President  shall be  authorized  to execute  and
deliver,  in the name and on behalf of the corporation,  all agreements,  bonds,
contracts, deeds, mortgages, and other instruments, either for the Corporation's
own  account  or  in a  fiduciary  or  other  capacity,  and  the  seal  of  the
corporation, if appropriate, shall be affixed thereto by any of such officers or
the Secretary or an Assistant Secretary. The Board of Directors, the Chairman of
the  Board,  the  President  or any Vice  President  designated  by the Board of
Directors  may  authorize  any other  officer,  employee or agent to execute and
deliver,  in the name  and on  behalf  of the  Corporation,  agreements,  bonds,
contracts, deeds, mortgages, and other instruments, either for the Corporation's
own account or in a fiduciary or other capacity,  and, if appropriate,  to affix
the seal of the Corporation thereto. The grant of such authority by the Board or
any such officer may be general or confined to specific instances.

Directors, the Chairman of the Board or the President.

<PAGE>



                           "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

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.

operation of the business of RIGINC or RIGLP (or its own business) following the
transactions  contemplated  hereby shall be in effect,  nor shall any proceeding
brought  by  an  administrative  agency  or  commission  or  other  governmental
authority or instrumentality,  domestic or foreign, seeking any of the foregoing
be pending.  There shall be no action,  suit,  claim or proceeding of any nature
pending or threatened,  against Parent, its properties or any of its officers or
directors,  that could  materially  and adversely  affect the business,  assets,
liabilities,  financial  condition,  results of  operations  or prospects of the
Parent and its subsidiaries taken as a whole.

of  Wilmer,  Cutler &  Pickering,  counsel to  Parent,  to the  effect  that the

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  to the  transactions  contemplated

Agreement  pursuant to Section  10.1,  this  Agreement  shall  forthwith  become

agreements and understandings between or among the parties regarding the subject
matter hereof,  whether written or oral, are superseded by this Agreement.  This
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.

warranties  made by the  Contributing  Parties and Parent in or pursuant to this

                       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
<PAGE>




                  (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
valued at the average  Closing  Price of Parent  Common Stock on the twenty (20)
trading days immediately preceding the date of settlement or final determination
of such claim.  "Closing  Price" on any trading day shall mean the closing  sale
price of Parent Common Stock on NASDAQ (or such other principal quotation system
or national  securities exchange on which the Parent Common Stock is admitted to
trading or quoted or listed) or, if not  admitted to trading or quoted or listed
on any  quotation  system or national  securities  exchange,  the average of the
closing bid and asked prices of the Parent Common Stock on the  over-the-counter
market on the day in  question  as reported  by the  National  Quotation  Bureau
Incorporated,  or a similarly generally accepted reporting service, or if not so
available in such manner, as reasonably determined by an independent  accounting
firm  designated  by the  parties  that has not  represented  any of the parties
hereto, their affiliates,  successors or assigns at any time during the two-year
period immediately preceding the day in question.

         1.5      STOCKHOLDERS' REPRESENTATIVE.

                  (a) Each  holder of Company  Common  Stock,  by  signing  this
Agreement,  designates  Leslie Lees  Jamison,  or, in the event that Leslie Lees
Jamison  is  unable  or  unwilling  to  serve,  Henry D.  Jamison,  IV to be the
Stockholders'  Representative  for purposes of this Agreement.  The Stockholders
shall be bound by any and all actions taken by the Stockholders'  Representative
on their behalf.

                  (b) Parent shall be entitled to rely upon any communication or
writings given or executed by the Stockholders'  Representative.  All notices to

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).

Stockholder shall make any disclosure (whether or not in response to an inquiry)

"Damages")  suffered,  sustained,  incurred  or paid by the  Parent  Indemnified
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

omission  to state  therein a  material  fact  relating  to the  Company  or the
Stockholders  required to be stated  therein or necessary to make the statements
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
Parties set forth in this Agreement or any schedule or certificate, delivered by
or on behalf of the RIG Parties in connection herewith; or

                  (b) any nonfulfillment of any covenant or agreement by the RIG

                  (c) any untrue  statement  or alleged  untrue  statement  of a
material fact relating to any RIG Party contained in any preliminary prospectus,
the  Registration  Statement or any  prospectus  forming a part thereof,  or any

Party required to be stated therein or necessary to make the statements  therein
not misleading.

         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.

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

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.
