PROSPECTUS
   
$250,000,000     
   
EXPERIAN INFORMATION SOLUTIONS, INC.     
to be merged into
INFORMATION SYSTEMS AND SERVICES, INC.
   % SENIOR SUBORDINATED NOTES DUE 2006
   
Experian Information Solutions, Inc. ("Experian"), which will merge into
Information Systems and Services, Inc. ("IS&S"), the information systems and
services business of TRW Inc., is offering (the "Offering") $250,000,000
aggregate principal amount of    % Senior Subordinated Notes due 2006 (the
"Notes"). As a result of the merger, IS&S will become liable for the Notes and
is expected to change its name to Experian Information Solutions, Inc. The net
proceeds from the Offering, together with the borrowings under the Credit
Facilities (as defined herein) and the Equity Investment (as defined herein),
will be used to finance the recapitalization (the "Recapitalization") of IS&S
and certain related transactions. The Offering is contingent upon, among other
things, consummation of the Recapitalization. The Recapitalization is being
effected in order to permit TRW to withdraw capital from IS&S and to permit the
shareholders of Experian Corporation, Experian's parent company, to acquire
equity interests in IS&S Holdings, Inc., IS&S's parent company. Neither
Experian nor Experian Corporation will have any operations prior or subsequent
to the consummation of the Recapitalization. See "The Recapitalization,
Financing and Related Transactions."     
   
Interest on the Notes is payable semi-annually on    and     of each year,
commencing on    , 1997, at the rate of   % per annum. The Notes will mature on
   , 2006. Except as described below, Experian may not redeem the Notes prior
to    , 2001. On or after such date, Experian may redeem the Notes, in whole or
in part, at the redemption prices set forth herein, together with accrued and
unpaid interest, if any, to the date of redemption. In addition, at any time
and from time to time on or prior to    , 1999, Experian may, subject to
certain requirements, redeem up to 40% of the original aggregate principal
amount of the Notes, with the net cash proceeds of one or more Equity Offerings
(as defined herein) at a price equal to    % of the principal amount of the
Notes to be redeemed, plus accrued and unpaid interest, if any, to the date of
redemption, provided that at least $  million of the original aggregate
principal amount of the Notes remains outstanding after each such redemption.
The Notes will not be subject to any sinking fund requirement. Upon the
occurrence of a Change of Control Triggering Event (as defined herein),
Experian will be required to make an offer to repurchase the Notes at a price
equal to 101% of the principal amount thereof, together with accrued and unpaid
interest, if any, to the date of repurchase. See "Description of Notes."     
   
The Notes will be unsecured obligations of Experian and will be subordinated to
all existing and future Senior Indebtedness (as defined herein), will rank pari
passu with any future Senior Subordinated Indebtedness (as defined herein) and
will rank senior to all future subordinated indebtedness of Experian. The Notes
will be effectively subordinated to all existing and future secured
indebtedness of Experian to the extent of the value of the assets securing such
indebtedness. At March 31, 1996, on a pro forma basis after giving effect to
the issuance of the Notes and the consummation of the Transactions (as defined
herein), the aggregate amount of Senior Indebtedness (including the Credit
Facilities) would have been approximately $561.7 million (all of which would
have been secured indebtedness) and unused commitments of up to $65.0 million
would have been available under the Credit Facilities and there would have been
no Senior Subordinated Indebtedness outstanding other than the Notes. The
indenture (the "Indenture") pursuant to which the Notes are to be issued
permits Experian and its subsidiaries to incur additional indebtedness. See
"Description of Notes."

                                  THE COMPANY
 
OVERVIEW
 
  The Company is a leading provider of credit, marketing and real estate
information on individuals, businesses and properties in the United States. The
Company's products and services play a key role in financial risk management as
well as customer identification, acquisition and retention for businesses in a
wide range of industries including financial services, retail, real estate,
telecommunications and utilities. For the latest twelve-month period ended
March 31, 1996, the Company generated sales of $550.2 million and pro forma
EBITDA (as defined) of $176.7 million. Increased demand for the Company's core
products and expanded applications for reliable credit and marketing
information have contributed to the Company's growth and profitability.
 
  Over the last 25 years, the Company has developed expertise in collecting,
screening and organizing volumes of data into its five proprietary databases
(the "Databases"). The Databases--consumer credit, business credit, consumer
demographic, business marketing and real estate--contain information on over
190 million people, 93% of households and 12 million businesses in the United
States. The Company updates the Databases with an average of over 40 million
pieces of information daily from credit grantors, public records and
proprietary sources. Management believes that the Databases represent the
broadest and most current collection of such information in the United States.
The Company utilizes the Databases to create a variety of products and services
designed to address the information needs of its customers and continually
seeks to improve the quality and breadth of its product offerings. In [   ]
1996, the Company will implement a new relational database system ("File One")
for its consumer credit database which the Company believes (among other
benefits) will enhance and expedite product development in a cost-effective
manner.
 
  The Company sells three major categories of information products and
services: credit, marketing and real estate. The Company's over 500-person
direct sales force emphasizes a consultative selling approach for the Company's
larger customers, substantially all of whom have had relationships with the
Company for more than a decade. In addition, the Company services smaller
customers through telemarketing facilities and through resellers, brokers and
credit bureaus.
 
Credit Information
 
  Credit products and services are critical to issuers of credit because they
identify credit extension risks and provide a cost-effective method of
monitoring outstanding credit portfolios. Customers use the Company's credit
products and services in a variety of applications including the issuance and
monitoring of credit cards, mortgages, small business loans and trade credit.
These products and services include credit profile reports, credit scoring
services, customized account management, on-line support for instant credit
decisions, accounts receivable evaluations and fraud detection. The
 
                                       3
<PAGE>
 
Company believes that it is one of the two largest providers of consumer credit
information and the second largest provider of business credit information in
the United States. Marketdata Enterprises estimates that the consumer credit
reporting industry has grown from approximately $1.37 billion in revenues in
1992 to approximately $1.63 billion in revenues in 1995, a compound annual
growth rate of 5.9%. Management believes that the portion of the market in
which the Company competes was approximately $875 million in revenues in 1995.
Furthermore, Marketdata Enterprises estimates the business credit reporting
industry has grown from approximately $920 million in revenues in 1992 to
approximately $1 billion in revenues in 1995, a compound annual growth rate of
2.8%. Management believes that the portion of the market in which the Company
competes was approximately $600 million in revenues in 1995.
 
Marketing Information
 
  Marketing products and services enable businesses to identify, retain and
cross-sell both new and existing customers in a targeted, cost-effective
manner. The Company uses selected credit and demographic data to develop and
sell prescreened lists of individuals and businesses to whom financial
institutions and retailers extend pre-approved offers of credit. Additionally,
the Company uses its demographic and real estate data, enhanced by the non-
restricted information (primarily name, address, telephone number and social
security number) in its credit databases, to develop and sell targeted
marketing products and services to financial institutions, consumer products
companies, retailers, telecommunications companies and other consumer and
business-to-business marketers. Targeted marketing products and services
include the development of lists of potential customers, value-added
enhancements to customer lists, the creation of marketing databases and other
analytical tools. The Company believes it is the largest provider of prescreen
services in North America, an industry which the Company believes had revenues
of approximately $200 million in 1995, and which has grown at a compound annual
growth rate of 39% since 1992. According to a 1995 study commissioned by the
Direct Marketing Association, total direct mail related expenditures were
estimated to be approximately $31 billion in 1995, up from approximately $23
billion in 1990, a compound annual growth rate of 5.9%. Management believes
that the portion of the market in which the Company competes was approximately
$5 billion in 1995.
 
Real Estate Information
 
  Real estate products and services provide appraisers, realtors, lenders,
government agencies and title companies with property, title and tax
information necessary for the property transfer and financing process. The
Company has detailed property data for 349 counties nationwide, and property
title and tax data for 80 counties in eight western states, representing
approximately 55% and 17%, respectively, of the U.S. population. The Company is
the national leader in both property data and title information services.
Management believes that the Company's 1995 sales of real estate products and
services were twice as large as the sales of its nearest competitors.

            THE RECAPITALIZATION, FINANCING AND RELATED TRANSACTIONS
   
  The Offering is part of the Recapitalization which is being effected pursuant
to the Recapitalization Agreement dated as of February 9, 1996 among TRW,
certain TRW subsidiaries and a Delaware corporation owned by the Investors
described below ("Experian Corporation"). TRW owns all of the outstanding stock
of IS&S Holdings, Inc. ("Holdings"), and Holdings owns all of the outstanding
stock of IS&S. IS&S will own substantially all of the assets of TRW IS&S and
will issue a demand promissory note to TRW in the face amount of approximately
$755.0 million (the "TRW Note"). The other principal components of the
Recapitalization, which will be consummated concurrently with the Offering,
include the following:     
     
  .  Bain Capital, Inc. and its affiliates (collectively "Bain"), Thomas H.
     Lee Company and its affiliates (collectively, "THL") and certain other
     investors (Bain, THL and such other investors are collectively referred
     to as the "Investors") will invest $255.0 million (the "Equity
     Investment") in Experian Corporation. Experian Corporation owns all of
     the outstanding capital stock of Experian. Bain and THL are two of the
     most active private equity investors in the United States.     
     
  .  Experian Corporation will merge into Holdings, and Experian will merge
     into IS&S (the "IS&S Merger") with IS&S becoming liable for the Notes.
     After the IS&S Merger, IS&S is expected to change its name to Experian
     Information Solutions, Inc. Neither Experian nor Experian Corporation
     will have any operations prior or subsequent to the consummation of the
     Recapitalization.     
     
  .  The proceeds of the Offering, together with estimated initial borrowings
     by the Company of $560.0 million under the Credit Facilities and the
     proceeds from the Equity Investment, will be used to (i) repay the TRW
     Note; (ii) pay TRW $255.0 million in connection with the redemption of
     certain stock of TRW in Holdings; and (iii) pay an estimated $55.0
     million of fees and expenses relating to the Recapitalization, the
     Offering, the Credit Facilities, the Equity Investment and the other
     transactions contemplated by the Recapitalization Agreement
     (collectively, the "Transactions").     
   
  Upon completion of the Recapitalization, Holdings will own all of the
outstanding capital stock of the Company. Bain will own approximately 33.6% of
the voting power of Holdings, THL will own approximately 33.6% of the voting
power of Holdings, TRW will retain securities entitled to approximately 19.6%
of the voting power of Holdings and certain other investors will own
approximately 13.2% of the voting power of Holdings. See "Risk Factors--
Controlling Stockholders," "Ownership of Capital Stock" and "Certain
Relationships and Related Transactions."     
 
  The Company will have certain rights to use the TRW name for a limited time
following the Recapitalization. See "Risk Factors--Effects of the
Recapitalization" and "Certain Relationships and Related Transactions."

                                  THE OFFERING

                        Notes and will merge into IS&S in connection with the
                        Recapitalization, with IS&S becoming liable for the

                        name to Experian Information Solutions, Inc.     
 
                           
Securities Offered....  $250,000,000 aggregate principal amount of  % Senior
                        Subordinated Notes due 2006.

                        commencing       , 1997.     
 
Sinking Fund..........  None.
 
Optional Redemption...  The Notes are redeemable, in whole or in part, at the
                        option of the Company on or after    , 2001, at the
                        redemption prices set forth herein plus accrued and
                        unpaid interest, if any, to the date of redemption. In
                        addition, prior to     , 1999, the Company, at its
                        option, may redeem up to 40% of the aggregate principal
                        amount of the Notes originally issued in the Offering
                        with the net cash proceeds of one or more Equity
                        Offerings, at a redemption price equal to     % of the
                        principal amount thereof plus accrued and unpaid
                        interest, if any, to the date of redemption; provided
                        that at least $   million of the original principal
                        amount of Notes remains outstanding after any such
                        redemption.
 
                           
Change of Control.....  Upon a Change of Control Triggering Event, the Company
                        will be required to make an offer to repurchase the
                        Notes at a price equal to 101% of the principal amount
                        thereof, together with accrued and unpaid interest, if
                        any, to the date of repurchase. There can be no
                        assurance that the Company would have the financial
                        resources necessary to repurchase the Notes upon a
                        Change of Control Triggering Event. The occurrence of
                        certain of the events which would constitute a Change
                        of Control Triggering Event as well as the failure to
                        repurchase the Notes upon a Change of Control
                        Triggering Event would constitute a default under the
                        Credit Facilities. As of March 31, 1996, on a pro forma
                        basis after giving effect to the issuance of the Notes
                        and the consummation of the Transactions, the aggregate
                        indebtedness that would have become due upon the
                        occurrence of a Change of Control Triggering Event
                        under the Indenture and a default under the Credit
                        Facilities was $812.5 million.     
 
Ranking...............  The Notes will be general unsecured obligations of the
                        Company and will be subordinated in right of payment to
                        all existing and future Senior Indebtedness of the
                        Company. The Notes will rank pari passu with any future
                        Senior Subordinated Indebtedness of the Company and
                        will

                        rank senior to all future subordinated indebtedness of
                        the Company. As of March 31, 1996, on a pro forma basis
                        after giving effect to the Transactions, the Company
                        would have had approximately $561.7 million of Senior
                        Indebtedness. The Indenture permits the Company to
                        incur indebtedness in addition to the Notes of up to
                        approximately $   million (including the Credit
                        Facilities) and certain other indebtedness as described
                        in the definition of "Permitted Indebtedness", as well
                        as an additional amount pursuant to a fixed charge
                        coverage ratio test that as of March 31, 1996, on a pro
                        forma basis after giving effect to the issuance of the
                        Notes and the consummation of the Transactions, would
                        have permitted the incurrence of an additional
                        approximately $   of indebtedness. See "Description of
                        Notes--Limitation on Incurrence of Additional
                        Indebtedness." The Indenture permits all of such
                        additional indebtedness to be Senior Indebtedness or
                        Secured Indebtedness.     
 
Restrictive                
Covenants.............  The Indenture will contain certain covenants that limit
                        the ability of the Company and certain of its
                        subsidiaries to, among other things, incur additional
                        indebtedness, pay dividends or make certain other
                        restricted payments, consummate certain asset sales,
                        enter into certain transactions with affiliates, incur
                        indebtedness that is subordinate in right of payment to
                        any Senior Indebtedness and senior in right of payment
                        to the Notes, incur liens, impose restrictions on the
                        ability of a subsidiary to pay dividends or make
                        certain payments to the Company and its subsidiaries,
                        merge or consolidate with any other person or sell,
                        assign, transfer, lease, convey or otherwise dispose of
                        all or substantially all of the assets of the Company.
                        The Indenture permits the Company to incur substantial
                        additional indebtedness under certain circumstances.
                        See "Ranking" above.     
 
Future Guarantees.....  The Indenture will provide that any subsidiary of the
                        Company which guarantees the Company's indebtedness
                        under the Credit Facilities will guarantee the Notes,
                        on an unsecured senior subordinated basis.
 
                           
Use of Proceeds.......  The Company intends to use the proceeds from the
                        Offering, together with estimated initial borrowings of
                        approximately $560.0 million under the Credit
                        Facilities and the proceeds of the Equity Investment as
                        follows: (i) approximately $755.0 million will be
                        applied to repay the TRW Note; (ii) approximately
                        $255.0 will be paid to TRW in connection with the
                        redemption of certain stock of TRW in Holdings; and
                        (iii) an estimated $55.0 million will be applied to pay
                        fees and expenses relating to the Transactions. See
                        "Use of Proceeds" and "The Recapitalization, Financing

 (1) In 1991, the Company recorded restructuring charges totalling
     approximately $47 million consisting of approximately: (i) $30 million
     pursuant to workforce reductions and the consolidation of facilities; (ii)
     $11 million in connection with the planned closing of one of its
     businesses; and (iii) $6 million for severance costs, facility relocations
     and personnel consolidations in connection with TRW REDI. In 1992, the
     approximately $11 million reserve for the planned closure of one of its
     businesses and approximately $7 million of additional unutilized reserves
     recorded in 1991 were reversed. In 1993 and 1994, the Company recorded
     restructuring charges totaling $3.6 million and $3.9 million,
     respectively, principally relating to costs incurred for the relocation of
     the Company's data center from Orange, California to Allen, Texas. In
     1994, the Company recorded an additional restructuring charge of $8.8
     million to cover the costs of closing, downsizing, and relocating
     facilities and restructuring of TRW REDI. In 1995, the Company reduced
     excess restructuring reserves by $3.3 million, none of which was recorded
     in the first quarter.
 
 (2) TRW corporate incurs certain general and administrative expenses including
     treasury and tax management, benefits administration, shareholder services
     and general corporate governance on behalf of all of its operating units
     which are allocated based upon each operating unit's cost of operations.
 
 (3) In 1993, the Company recorded other expense totaling $10.6 million, of
     which $10.5 million related to the write-off of an intercompany note
     receivable from TRW RELS, a real estate appraisal and lending support
     business prior to its divestiture from TRW. In 1994, the Company recorded
     a gain of $17.7 million on the sale of Credentials, a direct-to-consumer
     credit monitoring business.
 
                                       11

 (4)  In 1992, the Company recorded a $3.5 million after tax charge for the
      cumulative effect of adopting SFAS 109 "Accounting For Income Taxes" and
      SFAS 106 "Accounting for Postretirement Benefits Other than Pensions." In
      1993, the Company recorded a $1.8 million after tax charge for the
      cumulative effect of adopting SFAS No. 112, "Employer's Accounting for
      Postemployment Benefits."
 
 (5)  "EBITDA" is defined herein as income before income taxes, plus
      depreciation and amortization expense and interest expense. EBITDA is
      presented because the Company believes it is a widely accepted financial
      indicator of a company's ability to service and/or incur indebtedness.
      However, EBITDA should not be considered as an alternative to net income
      as a measure of operating results or to cash flows as a measure of
      liquidity in accordance with generally accepted accounting principles.
   
 (6)  "Adjusted EBITDA" is defined herein as EBITDA adjusted for certain items
      of income and expense which are not expected to be incurred by the Company
      subsequent to the Transactions. These items consist of: the inclusion of
      the TRW REDI minority interest; restructuring charges (Note 1); operating
      income (losses) of divested operations, net of related depreciation and
      amortization expenses of $18.2, $18.7, $16.9, $11.2, $(2.2) and $(0.5)
      million in 1991, 1992, 1993, 1994, 1995 and in the three months ended
      March 31, 1995, respectively; elimination of TRW REDI royalty payments to
      the Company's parent and minority partner of $0.6, $1.9, $2.1, $1.9, $1.8,
      $0.4 and $0.3 million in 1991, 1992, 1993, 1994, 1995 and in the three
      months ended March 31, 1995 and 1996, respectively; gain on sale of the
      Credentials business in 1994, the Smart Charts/Search Access businesses in
      1995 and the write-off of an intercompany note receivable from TRW RELS
      (Note 3). See further explanation of these items in "Management's
      Discussion and Analysis of Financial Condition and Results of Operations."
      See the tabular presentation of Adjusted EBITDA in "Management's
      Discussion and Analysis of Financial Conditions and Results of 
      Operations--Liquidity and Capital Resources."     

 (7)  Information is not available for 1991 and is estimated for 1992.
 
 (8)  Expenditures for intangibles consists principally of capitalized data
      files and software products.
 
 (9)  For purposes of computing this ratio, earnings consist of income before
      income taxes and minority interest plus fixed charges. Fixed charges
      consist of interest expense and one-third of the rent expense from
      operating leases, which management believes is a reasonable approximation
      of an interest factor.

 (10) Earnings were insufficient to cover fixed charges by $16.1 million during
      the year ended December 31, 1991.

<PAGE>
 
                                 RISK FACTORS
 
  Prospective investors should carefully consider the following factors in
addition to other information included in this Prospectus before purchasing
any of the Notes.
 
SUBSTANTIAL LEVERAGE AND DEBT SERVICE OBLIGATIONS
 
  In connection with the Transactions, the Company will incur a significant
amount of indebtedness. As of March 31, 1996, on a pro forma basis after
giving effect to the Transactions as if they had occurred on such date, the
Company would have had outstanding indebtedness of $811.7 million (excluding
unused commitments) and its stockholders' deficit would have been
approximately $156.0 million. See "Capitalization" and "Unaudited Pro Forma
Financial Data." The Indenture will permit the Company to incur or guarantee
additional indebtedness, including indebtedness under the Credit Facilities,
subject to certain limitations. The Company will have additional borrowing
capacity on a revolving credit basis under the Credit Facilities upon
consummation of the Transactions. See "Description of Credit Facilities."
 
  The Company's high degree of leverage could have important consequences to
the holders of the Notes, including but not limited to the following: (i) a
substantial portion of the Company's cash flow from operations must be
dedicated to the payment of principal and interest on its indebtedness,
thereby reducing the funds available to the Company for other purposes; (ii)
the Company's ability to obtain additional financing for working capital,
capital expenditures, general corporate purposes or other purposes may be
impaired in the future; and (iii) the Company's flexibility to adjust to
changing market conditions and ability to withstand competitive pressures
could be limited, and the Company may be more vulnerable to a downturn in
general economic conditions or its business. See "Description of Credit
Facilities" and "Description of Notes."
 
  The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness will depend on its financial and
operating performance, which, in turn, is subject to prevailing economic and
competitive conditions and to certain financial, business and other factors
beyond its control, including operating difficulties, increased operating
costs, the response of competitors, regulatory developments and delays in
implementing strategic projects. The Company's ability to meet its debt
service and other obligations will depend in part on the extent to which the
Company can successfully implement its operating strategy. There can be no
assurance that the Company will be able to fully implement its strategy or
that the anticipated results of its strategy will be realized. See "Business--
Operating Strategy."
 
  If the Company's cash flow and capital resources are insufficient to fund
its debt service obligations, the Company may be forced to reduce or delay
capital expenditures, sell assets, seek to obtain additional equity capital or
to restructure its debt. There can be no assurance that the Company's cash
flow and capital resources will be sufficient for payment of interest on and
principal of its indebtedness in the future, or that any such alternative
measures would be successful or would permit the Company to meet its scheduled
debt service obligations. In the absence of such operating results and
resources, the Company could face substantial liquidity problems and might be
required to dispose of material assets or operations to meet its debt service
and other obligations, and there can be no assurance as to the timing of such
sales or the proceeds which the Company could realize therefrom.
 
RESTRICTIVE FINANCING COVENANTS
 
  The Credit Facilities will contain a number of significant covenants that,
among other things, will restrict the ability of the Company to dispose of
assets, incur additional indebtedness, incur guarantee obligations, repay debt
including the Notes, amend the terms of debt including the Indenture, pay
 
                                      15
<PAGE>
 
dividends, create liens on assets, make investments or loans, make
acquisitions, engage in mergers or consolidations, make capital expenditures
or engage in certain transactions with affiliates and change its business and
will otherwise restrict corporate activities. In addition, under the Credit
Facilities, the Company will be required to comply with specified financial
ratios and tests, including a maximum leverage ratio, an interest coverage
ratio, a fixed charge coverage ratio and an EBITDA covenant. See "Description
of Credit Facilities." The Indenture will also contain certain restrictive
covenants. See "Description of Notes."
 
  The Company's ability to comply with the covenants and restrictions
contained in the Credit Facilities and the Indenture may be affected by events
beyond its control, including prevailing economic, financial and industry
conditions. The breach of any such covenants or restrictions could result in a
default under the Credit Facilities or the Indenture which would permit the
lenders under the Credit Facilities or the holders of the Notes, as the case
may be, to declare all amounts outstanding thereunder to be due and payable,
together with accrued and unpaid interest, and the commitments of the lenders
under the Credit Facilities to make further extensions of credit under the
Credit Facilities could be terminated. If the Company were unable to repay its
indebtedness under the Credit Facilities, such lenders could proceed against
the collateral securing such indebtedness. See "Description of Credit
Facilities" and "Description of Notes."
 
UNSECURED STATUS OF THE NOTES
 
  The Indenture will permit the Company to incur certain secured indebtedness,
including indebtedness under the Credit Facilities. The Credit Facilities will
be secured by a lien on substantially all of the assets of the Company,
including pledges of all or a portion of the capital stock of the Company's
subsidiaries. The Notes are unsecured and therefore do not have the benefit of
such collateral. Accordingly, if an event of default occurs under the Credit
Facilities, the lenders under the Credit Facilities will have a prior right to
the assets of the Company, to the exclusion of the holders of the Notes. In
such event, such assets would first be used to repay in full amounts
outstanding under the Credit Facilities, resulting in all or a portion of the
Company's assets being unavailable to satisfy the claims of the holders of
Notes and other unsecured indebtedness. See "Description of Credit Facilities"
and "Description of Notes."
 
SUBORDINATION OF THE NOTES
   
  The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the Notes will be subordinated to the prior
payment in full of all existing and future Senior Indebtedness, including all
amounts owing under the Credit Facilities. As of March 31, 1996, on a pro
forma basis after giving effect to the Transactions, the Company would have
had outstanding Senior Indebtedness of $561.7 million (excluding unused
commitments). Consequently, in the event of a bankruptcy, liquidation,
dissolution, reorganization or similar proceeding with respect to the Company,
assets of the Company (whether or not pledged as security to the holders of
Senior Indebtedness) would be available to pay obligations of the Notes only
after all Senior Indebtedness has been paid in full in cash or cash
equivalents, and there can be no assurance that there will be sufficient
assets to pay amounts due on all or any of the Notes. See "Description of
Notes."     
 
CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control Triggering Event (as defined in
the Indenture), the Company will be required to make an offer to purchase all
of the outstanding Notes at a price equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of purchase. The
occurrence of certain of the events which would constitute a Change of Control
Triggering Event would constitute a default under the Credit Facilities. In
addition, the Credit Facilities will prohibit the purchase of the Notes by the
Company in the event of a Change of Control Triggering Event, unless and until
such time as the indebtedness under the Credit Facilities is repaid in full.
The Company's failure to purchase the Notes in such instance would result in a
default under the Indenture and the
 
                                      16
<PAGE>
 
   
Credit Facilities. The inability to repay the indebtedness under the Credit
Facilities, if accelerated, would also constitute an event of default under
the Indenture, which could have materially adverse consequences to the Company
and to the holders of the Notes. In the event of a Change of Control
Triggering Event, there can be no assurance that the Company would have
sufficient assets to satisfy all of its obligations under the Credit
Facilities and the Notes and other indebtedness required to be repurchased
upon a Change of Control Triggering Event. As of March 31, 1996, on a pro
forma basis after giving effect to the issuance of the Notes and the
consummation of the Transactions, the aggregate indebtedness that would have
become due upon the occurrence of a Change of Control Triggering Event under
the Indenture and a default under the Credit Facilities was $812.5 million.
See "Description of Notes--Change of Control" and "Description of Credit
Facilities."     
 
CONTROLLING STOCKHOLDERS
   
  Upon completion of the Transactions, the Company will be a wholly-owned
subsidiary of Holdings. Bain will own approximately 33.6% of Holdings' voting
power, THL will own approximately 33.6% of Holdings' voting power and TRW will
retain securities entitled to approximately 19.6% of Holdings' voting power.
After the completion of the Transactions, Bain will be entitled to designate
up to four persons to the Board of Directors of Holdings and the Company, THL
will be entitled to designate up to four persons to the Board of Directors of
Holdings and the Company and TRW will be entitled to designate one person to
the Board of Directors of Holdings and the Company. An additional four
directors may be appointed jointly by Bain and THL, three from among
management and one a non-employee. Accordingly, Bain, THL and TRW will control
the board of directors and business and operations of the Company. See
"Certain Relationships and Related Transactions."     
 
DEMAND FOR CONSUMER CREDIT INFORMATION
 
  The Company's core product is its consumer credit profile. In general, the
usage of credit profiles (and related services) is driven by consumer demand
for credit (via new credit cards, automobile loans, home mortgages and
refinancings and other consumer loans) and lenders' efforts to develop new,
and monitor existing, credit relationships. Consumer demand for credit tends
to increase during periods of economic expansion, and lenders' efforts to
monitor existing credit relationships tend to increase during periods of
economic contraction. Consequently, revenue from consumer credit information
products is influenced by cyclical economic trends related to consumer debt.
 
GOVERNMENT REGULATION; PRIVACY ISSUES
 
  The Company's business involves the collection of consumer and business data
and the distribution of such information to businesses making credit and
marketing decisions. Growing concerns about individual privacy and the
collection, distribution and use of information about individuals have led to
substantial governmental regulation of the credit reporting industry, limited
government regulation of the direct marketing industry and self-regulation by
the direct marketing industry through guidelines suggested by the Direct
Marketing Association.
 
  The credit reporting industry is regulated under the federal Fair Credit
Reporting Act of 1970, as amended (the "FCRA") and by legislation in many
states. The credit reporting industry and the direct marketing industry have
recently been subject to increased legislative attention. Legislation has been
introduced in the United States Senate and House of Representatives seeking to
amend the FCRA to refine the legal treatment of certain credit reporting
practices, including provisions codifying rules applicable to prescreening. In
addition to the federal bills, numerous bills are pending in various state
legislatures. Such bills are generally intended to regulate how personal
information is used in the marketplace. The Federal Trade Commission (the
"FTC") also recently implemented rules governing telemarketing. While
management does not believe that any of the proposed federal or state bills,
if passed as currently drafted, would have a material adverse effect on the
Company, there can be no assurance that pending or additional federal or state
consumer-oriented legislation will not significantly limit demand for, or
increase the costs of, certain of the Company's products. See "Business--
Regulatory."

EFFECTS OF THE RECAPITALIZATION
 
  The Company has operated as a part of TRW for over 25 years and has
consistently identified itself during that time using the names TRW and TRW
Information Systems & Services. Subject to certain restrictions, the
Recapitalization Agreement permits the Company to (i) use the TRW name in
connection with its products and services for two years after the Closing Date
and (ii) identify itself for one year after the Closing Date as having
formerly been TRW Information Systems & Services. There can be no assurance
that the Company will succeed in transferring the franchise value associated
with the TRW Information Systems & Services name to its new corporate name,
and the failure to do so could have a material adverse effect on the Company.
Also, there also can be no assurance that the Company, which has never
operated as a stand-alone entity, will succeed in doing so. See "The
Recapitalization, Financing and Related Transactions" and "Certain
Relationships and Related Transactions--Trademark Agreement."
 
COMPETITION
 
  The Company primarily competes with two national consumer credit reporting
companies, Equifax, Inc. and Trans Union Corp., and one national business
credit reporting company, Dun & Bradstreet Corp., which offer credit reporting
products that are similar to those offered by the Company. The Company also
competes with a number of companies which offer marketing information products
and services, including Acxiom Corporation, Database America Information
Services, Inc., Direct Marketing Technology, Inc., Donnelley Marketing, Inc.,
Equifax, Inc., Harte-Hanks Communications, May & Speh, Inc., Metromail
Corporation, Neodata Services, Inc., R.L. Polk & Co. and Trans Union Corp.
Certain of the Company's competitors are better capitalized than the Company
and may have greater financial and other resources than those available to the
Company. The Company believes that the principal competitive factors affecting
its business are price, product quality, customer service and technological
innovation.
 
  Unit prices for many of the Company's products, including its consumer
credit profile, have declined in recent years, due in part to competitive
conditions and the effect of technological change on the demand for, and cost
of delivery of, many such products. To date, declines in unit prices have been
more than offset by increases in unit volumes. There can be no assurance that
the Company will be able to continue to sustain unit growth or that future
unit price declines, if any, will be offset by increases in demand for the
Company's products. See "Business--Competition."
 
ACQUISITIONS AND ALLIANCES
 
  A key element of the Company's strategy is to pursue strategic acquisitions
of or alliances with companies that have products, services and technologies
or industry specializations that extend or complement those of the Company. To
date, the Company's management has had limited experience in making
acquisitions and entering into alliances. The process of integrating acquired
businesses may involve unforeseen difficulties and may require a
disproportionate amount of the time and attention of the Company's management
and the Company's financial and other resources. There can be no assurance
that the Company will be effective in identifying or making acquisitions or in
forging alliances, that any acquired business will be effectively integrated
or that any acquired business or alliance will be profitable.
 
RISKS ASSOCIATED WITH SYSTEMS UPGRADE
 
  The Company has invested and will continue to invest significant resources
in software development. In [  ] 1996, the Company will implement File One
which, among other things, will redesign the file structure of the Company's
consumer credit database. In the three years ended December 31, 1995, the
Company expended approximately $61 million in connection with the development
of File One, with an additional $8.7 million being expended during the first
quarter of 1996. There can be no assurance that this upgrade will adequately
address clients' requirements for performance and functionality. If it does
not, the Company's ability to introduce new and enhanced
 
                                      18
<PAGE>
 
products and services could be adversely affected. After the implementation of
File One, the Company will not continue to update the consumer credit
information in its existing flat file and will only update the consumer
information in File One. The Company has capitalized approximately $22.9
million of the expenditures associated with File One as of March 31, 1996. If
the Company is unable to recover its investment in File One, the Company would
be required to charge against earnings all or a portion of such capitalized
development costs, and such charge could be material.
 
RISK OF DATA CENTER FAILURE
   
  The Company's operations are dependent upon its ability to protect its data
center against damage from fire, power loss, telecommunications failure,
natural disaster or a similar event. Substantially all of the Company's
computer equipment and data operations are located in a single facility in
Allen, Texas. While the Company maintains off-site copies of all information
contained in its data bases, the Company does not have any arrangement through
which it would be able to use alternative data processing sites in the event
the Company experiences a natural disaster, hardware or software malfunction
or other interruption of its data center. As a result, the Company could be
materially adversely affected by damage or failure that causes significant
interruptions in the Company's operations. The Company's property and business
interruption insurance may not be adequate to compensate the Company for all
such losses that may occur. The Company's current insurance program provides
an all-risk limit for property damage and business interruption of $900
million, with various sublimits for ancillary coverages and $100 million
sublimits applicable separately to flood and earthquake. If the Company's data
center were unable to operate for an extended period of time, the Company
could find it difficult or impossible to maintain the accuracy and
completeness of the Databases. See "Business--Information Technologies."     
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company's success depends in part upon its technological expertise and
proprietary information and technologies. The Company relies on a combination
of copyright, trade secret and contract protection to establish and protect
its proprietary rights in its products and technology. The Company generally
enters into confidentiality agreements with its management and technical staff
and limits access to and distribution of its proprietary information. The
Company also has implemented a number of procedures and controls designed to
prohibit unauthorized access to the Company's computerized database. There can
be no assurance that these steps will be adequate to deter misappropriation or
infringement of the Company's proprietary technologies. Although the Company
believes that its products and technologies do not infringe any proprietary
rights of others, the growing use of copyrights and patents to protect
proprietary rights has increased the risk that third parties will increasingly
assert claims of infringement in the future. See "Business--Proprietary
Information."
 
FRAUDULENT TRANSFER CONSIDERATIONS
   
  In connection with the Transactions, IS&S will incur substantial
indebtedness, including the Credit Facilities and, through its assumption of
the Notes in connection with the IS&S Merger, the Notes. If, under relevant
federal and state fraudulent transfer and conveyance statutes, in a bankruptcy
or reorganization case or a lawsuit by or on behalf of unpaid creditors of
Experian or IS&S, a court were to find that, at the time the Notes were issued
by Experian or assumed by IS&S, (a) Experian issued or IS&S assumed the Notes
with the intent of hindering, delaying or defrauding current or future
creditors or (b) (i) Experian or IS&S received less than reasonably equivalent
value or fair consideration for issuing or assuming the Notes, as applicable,
and (ii) Experian or IS&S, as the case may be, (A) was insolvent or was
rendered insolvent by reason of any of the Transactions, including the
incurrence of the indebtedness to fund the Transactions, (B) was engaged, or
about to engage, in a business or transaction for which its assets constituted
unreasonably small capital, (C) intended to incur, or believed that it would
incur, debts beyond its ability to pay such debts as they matured (as all of
the foregoing     
 
                                      19
<PAGE>
 
   
terms are defined in or interpreted under the relevant fraudulent transfer or
conveyance statutes) or (D) was a defendant in an action for money damages, or
had a judgment for money damages docketed against it (if, in either case,
after final judgment the judgment is unsatisfied), such court could avoid or
subordinate the Notes to presently existing and future indebtedness of
Experian or IS&S and take other action detrimental to the holders of the
Notes, including, under certain circumstances, invalidating the Notes.     
   
  The measure of insolvency for purposes of the foregoing considerations will
vary depending upon the law of the jurisdiction that is being applied in any
such proceeding. Generally, however, Experian or IS&S would be considered
insolvent if, at the time it incurs the indebtedness constituting the Notes,
either (i) the sum of all its liabilities (including contingent liabilities)
is greater than its assets, at a fair valuation, or (ii) the present fair
saleable value of its assets is less than the amount required to pay the
probable liability on its debts and liabilities (including contingent
liabilities) as they become absolute and matured. There can be no assurance as
to what standards a court would use to determine whether Experian or IS&S was
solvent at the relevant time, or whether, whatever standard was used, the
Notes would not be avoided on another of the grounds set forth above.     
   
  Experian believes that, at the time the Notes are issued by Experian and
assumed by IS&S, each of Experian and IS&S (i) will be (a) neither insolvent
nor rendered insolvent thereby, (b) in possession of sufficient capital to run
its business effectively and (c) incurring debts within its abilities to pay
as the same mature or become due and (ii) will have sufficient assets to
satisfy any probable money judgment against it in any pending action. In
reaching the foregoing conclusions, Experian has relied upon its analyses of
internal cash flow projections and estimated values of assets and liabilities
of Experian and IS&S. There can be no assurance, however, that a court passing
on such questions would reach the same conclusions.     
 
  Initial borrowings under the Credit Facilities and the consummation of the
Offering is conditioned upon the receipt of an opinion from an independent
valuation firm to the effect that IS&S will be solvent as of the Closing Date
after giving effect to the Transactions. No assurance can be given, however,
that the assumptions and methodologies chosen by the independent valuation
firm in reaching its conclusions about the solvency of IS&S would be adopted
by a court or that a court would concur with those conclusions.
 
  In rendering their opinions in connection with the Offering, counsel for the
Company and counsel for the Underwriters will not express any opinion as to
the applicability of Federal or state fraudulent transfer and conveyance laws.
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES; POSSIBLE VOLATILITY OF THE NOTES
 
  The Notes are a new issue of securities with no established trading market
and the Company does not intend to have the Notes listed for trading on any
national securities exchange. The Underwriters have advised the Company that
they currently intend to make a market in the Notes, but the Underwriters are
not obligated to do so and any such market-making activity may be discontinued
at any time, without notice, in their sole discretion. Accordingly, no
assurance can be given as to the prices or liquidity of, or trading markets
for, the Notes. The liquidity of any market for the Notes will depend upon the
number of holders of the Notes, the interest of securities dealers in making a
market in the Notes and other factors. The absence of an active market for the
Notes could adversely affect the liquidity of the Notes. The liquidity of, and
trading markets for, the Notes may also be adversely affected by general
declines in the market for non-investment grade debt. Future trading prices
for the Notes will depend upon many factors, including, among others, the
Company's operating results, the market for similar securities and interest
rates.

                   EXPERIAN INFORMATION SOLUTIONS, INC.     
   
  Experian is a wholly owned subsidiary of Experian Corporation and was
organized to effectuate the Recapitalization. Upon consummation of the
Recapitalization, Experian will merge into IS&S, with IS&S becoming liable for
the Notes. After the merger, IS&S, an Ohio corporation, is expected to change
its name to Experian Information Solutions, Inc. Experian was incorporated in
May of 1996 under the laws of the State of Delaware.     
   
  The principal executive offices of Experian prior to the Recapitalization
will be located c/o Ropes & Gray, One International Place, Boston,
Massachusetts 02110, telephone number: (617) 951-7000, and the principal
executive offices of the Company after the Recapitalization will be located at
505 City Parkway West, Orange, California 92668, telephone number: (714) 385-
7000.     
 
           THE RECAPITALIZATION, FINANCING AND RELATED TRANSACTIONS
 
  The Offering is part of the Recapitalization which is being effected
pursuant to the Recapitalization Agreement. TRW owns all of the outstanding
stock of Holdings, and Holdings owns all of the outstanding stock of IS&S.
IS&S owns substantially all of the assets of TRW IS&S and will issue the TRW
Note. The other principal components of the Recapitalization, which will be
consummated concurrently with the Offering, include the following:
     
  .  The Investors, including Bain and THL, will make the Equity Investment
     in Experian Corporation. Experian Corporation owns all of the
     outstanding capital stock of Experian. Bain and THL are two of the most
     active private equity investors in the United States.     
     
  .  Experian Corporation will merge into Holdings, and Experian will be
     merged into IS&S with IS&S becoming liable for the Notes. After the IS&S
     Merger, IS&S is expected to change its name to Experian Information
     Solutions, Inc. Neither Experian nor Experian Corporation will have any
     operations prior or subsequent to the consummation of the
     Recapitalization.     
     
  .  The proceeds of the Offering, together with estimated initial borrowings
     by the Company of $560.0 million under the Credit Facilities and the
     proceeds from the Equity Investment, will be used to (i) repay the TRW
     Note; (ii) pay TRW $255.0 million in connection with the redemption of
     certain stock of TRW in Holdings; and (iii) pay an estimated $55.0
     million of fees and expenses relating to the Transactions. See "Use of
     Proceeds."     
   
  Upon completion of the Recapitalization, Holdings will own all of the
outstanding capital stock of the Company. Bain will own approximately 33.6% of
the voting power of Holdings, THL will own approximately 33.6% of the voting
power of Holdings, TRW will retain securities entitled to approximately 19.6%
of the voting power of Holdings and certain other investors will own
approximately 13.2% of the voting power of Holdings. See "Risk Factors--
Controlling Stockholders," "Ownership of Capital Stock" and "Certain
Relationships and Related Transactions."     
 
  The Company will have certain rights to use the TRW name for a limited time
following the Recapitalization. See "Risk Factors--Effects of the
Recapitalization" and "Certain Relationships and Related Transactions."

                                USE OF PROCEEDS
   
  The Company intends to use the proceeds from the Offering, together with
estimated initial borrowings of approximately $560.0 million under the Credit
Facilities and the proceeds of the Equity Investment, as follows: (i)
approximately $755.0 million will be applied to repay the TRW Note; (ii)
approximately $255.0 million will be paid to TRW in connection with the
redemption of certain stock of TRW in Holdings; and (iii) an estimated $55.0
million will be applied to pay fees and expenses related to the Transactions.
See "The Recapitalization, Financing and Related Transactions." The TRW Note
is a demand note that does not bear any interest.

  Management has identified cost reductions in excess of annual 1995 and three
months ended March 31, 1996 historical cost levels totalling approximately
$16,625 and $4,873, respectively. The foregoing cost reductions are not
included in pro forma income before income taxes and EBITDA. These cost
reductions are expected to be realized in part during 1996 and in full during
1997. These cost reductions are summarized as follows:

  (a) The reduction in File One developmental expenses is net of additional
      depreciation expense of $6,100 and $1,525 for the year ended December
      31, 1995 and the three months ended March 31, 1996, respectively.
      Excluding depreciation, the cash cost savings expected to be realized
      upon the completion of File One total $12,700 and $3,175 for the year
      ended December 31, 1995 and the three months ended March 31, 1996,
      respectively.
 
  The foregoing cost reductions are forward looking statements that involve
certain risks and uncertainties that could cause actual results to differ
materially from those contained herein. Potential risks and uncertainties
include such factors as the substantial leverage and debt service obligation
of the Company as a result of the Transactions, the demand for the Company's
products and services, government regulations and privacy issues, competition,
risk of data center failure, intellectual property rights and other risks
identified herein.
 
  Historically, the recapitalized businesses operated principally as a
separate and distinct business unit within the combined group of companies
comprising TRW. The unaudited pro forma financial data are based upon
assumptions that the Company believes are reasonable and should be read in
conjunction with the Combined Financial Statements of the Company and the
related notes thereto included elsewhere in this Prospectus.

An appraisal of the Company's assets will be obtained shortly after the
Recapitalization and any change from the estimate will either increase or
decrease the final amount of intangible assets for income tax reporting
purposes. Management believes that the final appraisal will not vary
materially from the preliminary estimate.
 
The valuation allowance represents the amount of the deferred tax assets
which, based on management's forecasts for future taxable income and other
relevant factors, may not be realized.
 
(3) Reflects the purchase of the remaining 40% partnership interest in TRW
    REDI which will be completed by TRW prior to, or contemporaneous with, the
    Recapitalization. Pursuant to a confidentiality agreement between TRW and
    the seller which precludes disclosure of the purchase price, management
    has recorded a purchase price for pro forma purposes equal to the net book
    value of the minority interest. As the acquisition of the remaining 40%
    interest will be funded by TRW, the estimated purchase price is accounted
    for as a contribution to capital, totalling $25,094.
   
(4) Represents the contribution of substantially all of the TRW IS&S
    historical assets and liabilities and the equity of TRW Hotel Company Inc.
    into TRW's wholly owned subsidiary, IS&S, and the issuance of the TRW Note
    in connection with the Reorganization. The historical TRW IS&S net
    investment account includes transactions of an intercompany nature related
    to deferred income taxes, employee benefit plans, other intercompany
    transactions and the residual net investment balance in TRW IS&S. At the
    date of the contribution, IS&S had 100 shares of no par value common stock
    outstanding.

(6) Represents the estimated recurring cost of providing health and other
    benefits to the Company's employees on a stand-alone basis. These benefits
    were previously provided as part of "corporate wide" TRW plans which
    resulted in allocations to the Company totalling $6,470, $1,618 and $1,666
    for the year ended December 31, 1995 and the three months ended March 31,
    1995 and 1996, respectively. As a result of the Transactions, the Company
    will no longer be allowed to participate in these plans. As a result,
    management has developed its own benefits package for its employees, at an
    annual estimated recurring cost of $4,000 ($4,120 in 1996) resulting in a
    net cost reduction of $2,470, $618 and $636 for the year ended December
    31, 1995 and the three months ended March 31, 1995 and 1996, respectively.
    These costs are allocated 50% to cost of sales and 50% to administrative
    and selling expenses.
 
(7) Represents management's estimate of the recurring cost of performing
    certain activities previously provided by TRW. Historically, TRW incurred
    certain general and administrative expenses including treasury management,
    benefits administration and governmental relations on behalf of all of its
    operating units which were allocated based upon each operating unit's cost
    of operations. As a result of the Transactions, these services are no
    longer available from TRW. The summary of the Company's expected stand-
    alone costs is set forth below:

  (a) Pro forma interest expense for the three months ended March 31, 1995
      and 1996 assumes pro forma indebtedness as of December 31, 1995 was
      outstanding for 90 days. The Credit Facilities do not require principal
      payments until eighteen months subsequent to the Closing Date.
 
(9) "EBITDA" is defined herein as income before income taxes, plus
    depreciation and amortization expense and interest expense. EBITDA is
    presented because the Company believes it is a widely accepted financial
    indicator of a company's ability to service and/or incur indebtedness.
    However, EBITDA should not be considered as an alternative to net income
    as a measure of operating results or to cash flows as a measure of
    liquidity in accordance with generally accepted accounting principles.

 (1) In 1991, the Company recorded restructuring charges totalling
     approximately $47 million consisting of approximately: (i) $30 million
     pursuant to workforce reductions and the consolidation of the facilities;
     (ii) $11 million in connection with the planned closing of one of its
     businesses; and (iii) $6 million for severance costs, facility
     relocations and personnel consolidations in connection with TRW REDI. In
     1992, the approximately $11 million reserve for the planned closure of
     one of its businesses and approximately $7 million of additional
     unutilized reserves recorded in 1991 were reversed. In 1993 and 1994, the
     Company recorded restructuring charges totaling $3.6 million and $3.9
     million, respectively, principally relating to costs incurred for the
     relocation of the Company's data center from Orange, California to Allen,
     Texas. In 1994, the Company recorded an additional restructuring charge
     of $8.8 million to cover the costs of closing, downsizing, and relocating
     facilities and restructuring of TRW REDI. In 1995, the Company reduced
     restructuring reserves by $3.3 million, none of which was recorded in the
     first quarter.
 
 (2) TRW corporate incurs certain general and administrative expenses
     including treasury and tax management, benefits administration,
     shareholder services and general corporate governance on behalf of all of
     its operating units which are allocated based upon each operating unit's
     cost of operations.
 
 (3) In 1993, the Company recorded other expense totaling $10.6 million, of
     which $10.5 million related to the write-off of an intercompany note
     receivable from TRW RELS, a real estate appraisal and lending support
     business prior to its divestiture from TRW. In 1994, the Company recorded
     a gain of $17.7 million on the sale of Credentials, a direct-to-consumer
     credit monitoring business.
 
 (4) In 1992, the Company recorded a $3.5 million after tax charge for the
     cumulative effect of adopting SFAS 109 "Accounting For Income Taxes" and
     SFAS 106 "Accounting for Postretirement Benefits Other than Pensions." In
     1993, the Company recorded a $1.8 million after tax charge for the
     cumulative effect of adopting SFAS No. 112, "Employer's Accounting for
     Postemployment Benefits."
 
 (5) "EBITDA" is defined herein as income before income taxes, plus
     depreciation and amortization expense and interest expense. EBITDA is
     presented because the Company believes it is a widely accepted financial
     indicator of a company's ability to service and/or incur indebtedness.
     However, EBITDA should not be considered as an alternative to net income
     as a measure of operating results or to cash flows as a measure of
     liquidity in accordance with generally accepted accounting principles.
     "Adjusted EBITDA" is defined herein as EBITDA adjusted for certain items
     of income and expense which are not expected to be incurred by the
     Company subsequent to the Transactions. See Note 6 to the "Summary
     Historical Combined Financial Data" for a description of the principal
     components of Adjusted EBITDA.
 
 (6) Information is not available for 1991. The 1992 cash flow from operating
     activities is estimated.
 
 (7) Expenditures for intangibles consists principally of capitalized data
     files and software products.
 
 (8) For purposes of computing this ratio, earnings consist of income before
     taxes and minority interest plus fixed charges. Fixed charges consist of
     interest expense and one-third of the rent expense from operating leases,
     which management believes is a reasonable approximation of an interest
     factor.
 
 (9) Earnings were insufficient to cover fixed charges by $16.1 million during
     the year ended December 31, 1991.
 
(10) "Net Investment" includes transactions of an intercompany nature, related
     to deferred income taxes, employee benefit plans, other intercompany
     transactions and the residual net investment balance.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company is a leading provider of credit, marketing and real estate
information on individuals, businesses and properties in the United States.
The Company's products and services play a key role in financial risk
management as well as customer identification, acquisition and retention for
businesses in a wide range of industries including financial services, retail,
real estate, telecommunications and utilities. The Company sells three major
categories of information products and services: credit, marketing and real
estate. The Company's over 500-person direct sales force emphasizes a
consultative selling approach for its larger customers, substantially all of
whom have had relationships with the Company for more than a decade. In
addition, the Company services smaller customers through telemarketing
facilities and through resellers, brokers and credit bureaus.
 
Credit Information
 
  The Company believes that it is one of the two largest providers of consumer
credit information and the second largest provider of business credit
information in the United States. Customers use the Company's credit products
and services in a variety of applications including the issuance and
monitoring of credit cards, mortgages, small business loans and trade credit.
These products and services include credit profile reports, credit scoring
services, customized account management, on-line support for instant credit
decisions, accounts receivable evaluations and fraud detection. Credit
products and services sales were approximately $278 million, $286 million and
$315 million in 1993, 1994 and 1995, respectively, representing approximately
57%, 56% and 58% of the Company's sales in 1993, 1994 and 1995, respectively.
 
Marketing Information
 
  The Company believes it is the largest provider of prescreen services and a
leader in providing targeted marketing information services. The Company uses
its selected credit and demographic data to develop and sell prescreened lists
of individuals and businesses to whom financial institutions and retailers
extend pre-approved offers of credit. Additionally, the Company uses its
demographic and real estate data, enhanced by the non-restricted information
(primarily name, address, telephone number and social security number) in its
credit databases, to develop and sell targeted marketing products and services
to financial institutions, consumer products companies, retailers,
telecommunications companies and other consumer and business-to-business
marketers. Targeted marketing products and services include the development of
lists of potential customers, value-added enhancements to customer lists and
the creation of marketing databases and other analytical tools. Marketing
products and services sales were approximately $79 million, $112 million and
$134 million in 1993, 1994 and 1995, respectively, representing 16%, 22% and
25% of the Company's sales in 1993, 1994 and 1995, respectively.
 
Real Estate Information
 
  Management believes that the Company's 1995 sales of real estate products
and services were twice as large as the sales of its nearest competitors. Real
estate products and services provide appraisers, realtors, lenders, government
agencies and title companies with property, title and tax information
necessary for the property transfer and financing process. The Company is the
national leader in both property data and title information services. Real
estate information products and services sales were approximately $105
million, $99 million and $92 million in 1993, 1994 and 1995, respectively,
representing approximately 22%, 19% and 17% of the Company's sales in 1993,
1994 and 1995, respectively. Due to higher data acquisition and production
costs, real estate information products and services are substantially less
profitable than the Company's other products and services and, therefore, do
not contribute proportionately to the Company's net income.
 
  Credentials, a direct-to-consumer credit reporting service which was
divested in 1994, had sales of approximately $25 million (5% of the Company's
sales) in 1993 and $16 million (3% of the Company's sales) in 1994.
 
                                      38
<PAGE>
 
  The Company's sales and business operations benefit from well-established
customer relationships. Although the majority of the Company's sales is not
guaranteed under long-term contracts, a substantial portion of the Company's
sales are derived from customers with long-standing relationships with the
Company. Sales to the 25 largest customers amounted to approximately $97
million (20% of sales) in 1993, $122 million (24% of sales) in 1994, and $154
million (29% of sales) in 1995. No single customer accounted for more than
2.1% of sales in each of the three years.
 
  The Company's revenues and operating results are affected by several
economic trends which drive activity in the financial services sector. In
particular, the rate of economic growth, interest rates, consumer spending,
and consumer confidence influence demand for the Company's credit, marketing
and real estate information products and services. The effect of these
economic factors may be pronounced, as a significant portion of the Company's
expenses is fixed in nature. Historically, however, the adverse effects of an
economic downturn on credit reporting revenues have been partially offset by
increased demand for risk management and portfolio monitoring services in
these periods.
 
  The demand for target marketing services is also sensitive to the level of
postal rates and mailing costs, which may limit customers' solicitation and
marketing activities. List development and list enhancement services, which
allow Company customers to more closely target their product offerings, have
mitigated a portion of the revenue declines in periods when mailing costs
rise.
 
POTENTIAL OPERATING IMPROVEMENTS
 
  As more fully described under "Unaudited Pro Forma Financial Data,"
management has identified certain areas which are expected to produce future
cost reductions in excess of annual 1995 and three months ended March 31, 1996
historical cost levels totaling approximately $16.6 million and $4.9 million,
respectively. These cost reductions are expected to be realized in part during
1996 and in full during 1997.
 
RESULTS OF OPERATIONS
 
  The following table sets forth the percentage of sales for each of the
Company's product lines, and summarizes the related expenses and earnings
expressed as a percentage of sales for each of the three years ended December
31, 1993, 1994 and 1995 and for the three months ended March 31, 1995 and
1996:

THREE MONTHS ENDED MARCH 31, 1996 COMPARED TO THREE MONTHS ENDED MARCH 31,
1995
 
  Sales in the first quarter of 1996 increased 7.5% to $143.8 million, from
$133.8 million in the prior year's first quarter. Sales of credit products and
services rose 10.3% to $84.6 million, reflecting continuing gains in unit
volumes. Sales of marketing products and services increased by 5.3% to $35.9
million, principally as a result of higher sales of account management and
portfolio monitoring services.
 
  Real estate information services sales increased by 1.7% in the first
quarter of 1996 to $23.3 million from $22.9 million in the comparable prior
year's first quarter. Lower subscription revenues from traditional microfiche
and hard copy property data products were more than offset by increased sales
of title information electronically imaged products.
 
  Cost of sales amounted to $74.2 million in the first quarter of 1996, an
increase of 6.8% over the prior year's first quarter, reflecting the variable
costs associated with the increased sales volumes. Gross margin of 48.4% for
the first quarter of 1996 was comparable to 48.1% for the first quarter of
1995.
 
  Administrative and selling expenses totaled $38.1 million in the first
quarter of 1996, representing 26.5% of sales, compared to $38.1 million or
28.5% of sales in the first quarter of 1995.
 
  Research and development expenses in the first quarter of 1996 totaled $8.3
million, an increase of $5.9 million or 245.8% over the first quarter of 1995.
Development costs associated with File One and the introduction of improved
business processes for delivering consumer credit reporting services peaked in
the first quarter of 1996, as the Company prepared to launch the program into
production in the latter part of the second quarter of 1996. The Company does
not expect research and development expenses to be as high during subsequent
quarters.
 
  Research and development expenses for the full year 1996 are expected to
exceed the amounts expended in 1995 due to the increased level of development
and implementation activities associated with the File One system upgrade, and
are expected to decline thereafter upon its completion.
   
  The Company has invested in Comcred S.A. de CV ("Comcred"), a start-up
Mexican credit data company. The Company purchased 2,400 shares of Comcred's
Series B stock (20% interest) for $0.8 million. The Company has entered into
three note agreements which allow Comcred to draw down cash as necessary. As
of December 31, 1995 and March 31, 1996, the Company has principal and
interest totaling $4.5 million and $4.6 million, respectively, outstanding
under the notes. Two of the promissory notes have conversion features which
allow the Company to convert an amount of principal and interest that would
result in issuance of an additional 29% of Comcred's total voting securities.
The Company accounts for its investment in Comcred using the equity method of
accounting. During the three months ended March 31, 1996, the Company provided
an allowance of approximately $1.0 million, before tax, related to the notes
described above. Through March 31, 1996, the Company has recorded $1.0 million
of losses reflecting its share of the inception to date losses of Comcred.
    
1995 COMPARED TO 1994
 
  Sales in 1995 increased 5.4% to $540.2 million, from $512.3 million in 1994.
Excluding $16 million of revenue from Credentials, sales from the Company's
continuing products increased 8.9% in 1995 from 1994.
 
  Strong performances in both credit and marketing products and services drove
the increase in sales. Credit products and services sales in 1995 increased
10.1% from 1994 to $315 million, primarily as a result of a significant gain
in consumer credit unit volumes, which was partially offset by pricing
pressures. Sales of marketing products and services rose 19.7% to $134 million
in 1995, from $112 million in 1994. Approximately 42% of this increase came
from prescreening services used in conjunction with pre-approved credit
offerings. Consumer and business marketing list services comprised the balance
of this increase, reflecting the Company's increasing market penetration, as
well as investments in new products and increased selling efforts.
 
  Sales of real estate information products and services in 1995 declined 7.1%
to $92 million, from $99 million in 1994, due largely to a continuing
recession in California real estate markets which adversely affected real
estate revenues.
 
                                      40
<PAGE>
 
  Gross profit increased to $266.2 million in 1995 from $251.2 million in 1994
and improved slightly in 1995 as a percentage of sales to 49.3%. The increase
in gross profits in 1995 was due primarily to the increase in net sales of
credit and marketing products and services and increased operating
efficiencies and strong cost controls in other areas, which more than offset
declining net sales and high fixed costs in real estate information.
 
  Administrative and selling expenses increased 2.6% from 1994 to 1995 to
$151.1 million, but declined as a percentage of sales. The restructuring
effort in real estate information which began in 1994 led to reductions in
sales and administrative personnel and facility consolidations.
 
   Research and development expenses in 1995 totaled $24.9 million, or 4.6% of
sales. Expenses in this area increased 68.2% from 1994 due to the development
costs associated with File One and the development of improved business
processes for delivering consumer credit reporting services.
 
  Other income in 1994 totaled approximately $18.7 million, and was primarily
the result of a $17.7 million gain on the divestiture of Credentials, the
Company's direct-to-consumer credit reporting services.
 
1994 COMPARED TO 1993
 
  Sales in 1994 increased 5.3% to $512.3 million, from $486.4 million in 1993.
Virtually all of the increase was a result of increased mail solicitations by
the Company's customers and increased market penetration in marketing
information products and services, sales of which increased by 41.8% from $79
million to $112 million in 1994.
 
  Sales of credit products and services increased 2.9% in 1994 to $286 million
from $278 million in 1993, as a significant gain in consumer credit report
unit volumes was mostly offset by competitive pricing pressures.
 
  Sales of real estate information products and services declined 5.7% in 1994
to $99 million from $105 million in 1993, as rising interest rates limited
mortgage refinancing activity.
 
  Gross profit in 1994 increased to $251.2 million from $227.1 million in 1993
and increased as a percent of net sales to 49.0% in 1994 from 46.7% in 1993.
The Company's increased sales in credit and marketing products and services
more than offset the decline in real estate information sales, and the Company
realized cost efficiencies from the consolidation of data centers into the
Allen, Texas data processing center (the "Allen Data Center"), and other
quality and process improvement initiatives.
 
  Administrative and selling expenses in 1994 increased 4.7% from 1993,
reflecting the increase in sales.
 
  Research and development expenses in 1994 totaled $14.8 million, or 2.9% of
sales. Research and development expenses increased 25.4% in 1994 from 1993,
reflecting the Company's production costs associated with File One and the
development of improved business processes for delivering consumer credit
reporting services.
 
  Other expense in 1993 totaled approximately $10.6 million. This amount
includes a $10.5 million write-off of an intercompany note receivable from TRW
RELS, a real estate appraisal and lending support business, prior to its
divestiture from TRW.
 
RESTRUCTURING (INCOME) EXPENSE
 
  In 1993 and 1994, the Company recorded charges totaling $3.6 million and
$3.9 million, respectively, relating principally to the relocation and
consolidation of data centers from Orange, California and Richardson, Texas to
the Allen Data Center. This action was substantially completed during 1994. In
addition, the Company recorded a charge of $8.8 million in 1994 to provide for
the costs of downsizing, relocating facilities and restructuring of its real
estate information business. Several key elements of this program were
completed in 1995, including the payment of termination
 
                                      41
<PAGE>
 
benefits to approximately 167 employees, facility buy-outs, and the
consolidation of several facilities. In 1995, the Company reduced excess
restructuring reserves by $3.3 million, none of which was recorded in the
first quarter of 1995. The Company believes it maintains adequate reserves for
completion of the remaining actions, which are expected to be completed in
1997.
 
TRW CORPORATE GENERAL AND ADMINISTRATIVE EXPENSES
 
  TRW corporate expenses amounted to approximately 1.0% of sales, or $4.3
million, $4.4 million, $4.9 million, $1.2 million and $1.2 million in 1993,
1994, 1995 and in the three months ended March 31, 1995 and 1996,
respectively. Corporate headquarters costs, including treasury services, tax
management, shareholder services and general corporate governance are
allocated based upon each operating unit's cost of operations. The Company
believes that on a stand-alone basis, corporate general and administrative
expenses will be no more than in its historical experience.
 
EFFECTIVE INCOME TAX RATE
 
  The effective income tax rate in the first quarter of 1996 and in 1995 was
40.0% compared to 39.5% in 1994 and 42.3% in 1993. The effective income tax
rate for the first quarter of 1996 represents management's forecast of the
full year effective income tax rate which is not expected to vary
significantly from the prior year. The increase in the 1995 effective rate was
primarily attributable to higher non-tax deductible amortization of
intangibles arising from certain acquisitions. Most of the decrease from 1993
to 1994 was the result of an increase in the federal tax rate in 1993. The
remaining decrease was due to lower non-tax deductible amortization of
intangibles in 1994. As described in note 2 to the Unaudited Pro Forma
Combined Balanced Sheet (See "Unaudited Pro Forma Financial Data"), TRW's
Reorganization of the Company results in a new basis for the Company's assets
for income tax reporting purposes. Based on management's current projections,
the resulting increase in tax basis amortization, combined with increased
interest expense as a result of the Transactions will result in no federal
cash tax liabilities in each of the next three years.
 
EFFECTS OF INFLATION
 
  The Company believes inflation rates have been modest in recent years and
have not had a material effect on the Company's results of operations.

LIQUIDITY AND CAPITAL RESOURCES
 
  Net cash provided by operating activities for the three months ended March
31, 1996 totaled $9.8 million, a decrease of $4.4 million or 31.0% from the
three months ended March 31, 1995. This decrease was primarily the result of
the timing of cash disbursements between the quarters. Net cash provided by
operating activities in 1995 totaled $137.9 million, an increase of $18.0
million or 15% from the prior year. Growth in credit and marketing sales,
along with strong cost management contributed to the improvement in 1995
operating cash flow. Net cash provided by operating activities in 1993 totaled
$141.9 million, benefitting from a $38 million decrease in net working
capital.

(1) EBITDA is defined herein as income before taxes, plus depreciation and
    amortization expense and interest expense. EBITDA is presented because the
    Company believes it is a widely accepted financial indicator of a
    company's ability to service and/or incur indebtedness. However, EBITDA
    should not be considered as an alternative to net income as a measure of
    operating results or to cash flows as a measure of liquidity in accordance
    with generally accepted accounting principles.

    explanation of restructuring charges.
 
(4) Represents historical operating (income) losses of divested operations
    (Credentials in 1993 and 1994 and Smart Charts/Search Access in 1995), net
    of related depreciation and amortization expense.
 
(5) Represents the elimination of TRW REDI royalty payments to the Company's
    parent and minority partner which will not be payable subsequent to the
    Transactions.
 
(6) Represents the gain on sale of divested businesses (Credentials in 1994
    and Smart Charts/Search Access in 1995) and the write-off of an
    intercompany note receivable from TRW RELS. See note (3) to "Selected
    Historical Combined Financial Data" for further explanation.
 
  The Company's investing activities consist primarily of expenditures for
intangible assets and capital expenditures. Spending for intangible assets
totaled $13.7 million and $15.5 million for the three months ended March 31,
1995 and 1996, respectively, and $64.5 million, $61.5 million and $48.2
million in 1995, 1994 and 1993, respectively. Intangible assets primarily
include capitalized data acquisition costs and software development. Capital
expenditures are made principally for data center computing, and
telecommunications equipment in support of growth in existing products and new
initiatives, and distributed computing and office automation tools for
increased productivity. Capital expenditures totaled $1.8 million and $3.3
million for the three months ended March 31, 1995 and 1996, respectively, and
$17.0 million, $13.4 million and $20.2 million in 1995, 1994 and 1993,
respectively. Management anticipates spending on intangible assets and capital
expenditures for 1996 and 1997, respectively, to be approximately $85 million
and $75 million and does not expect significant increases from the 1997 level
in the subsequent periods.
 
  Historically, data acquisition costs, as well as capital expenditures and
research and development efforts sufficient to maintain competitiveness and
develop new product initiatives and normal working capital requirements were
met with internally generated funds.
 
  In connection with the Recapitalization, the Company will incur new
indebtedness aggregating approximately $810.0 million. Substantially all of
the proceeds of such indebtedness will be used to pay the TRW Note and pay
fees and expenses related to the Transactions. See "The Recapitalization,
Financing and Related Transactions."
 
                                      43
<PAGE>
 
  As a result of the Transactions, the Company will have significantly
increased cash requirements for debt service relating to the Notes and the
Credit Facilities. After the Transactions, the Company will rely on internally
generated funds and, to the extent necessary, on borrowings under the
Revolving Facility, which provides for borrowings up to $75.0 million, to meet
its liquidity needs. On a pro forma basis, at March 31, 1996, the Company
would have had borrowings of approximately $811.7 million and up to
approximately $65.0 million available under the Revolving Facility. The
Company's ability to borrow is limited under the Credit Facilities and the
Indenture. The Company's principal debt obligations, including the Credit
Facilities and the Notes, do not require principal payments within eighteen
months from the Closing Date. See "Description of Credit Facilities" and
"Description of Notes."
   
  The Company had working capital deficits of $10.1 million, $22.6 million and
$12.2 million in 1993, 1994 and 1995, respectively. Historically the Company
participated in TRW's centralized cash management system whereby all cash
receipts were "swept" daily into centralized corporate accounts. Net cash
transferred by the Company to TRW exceeded net earnings in 1993 and 1994, and
approximated net earnings in 1995. See the combined financial statements of
the Company included herein. The Company will not participate in TRW's
centralized cash management system after the Closing Date. As such, the
Company does not believe that historical working capital deficits are
indicative of its future working capital position.     
 
  Management believes that based on the current level of operations and
anticipated internal growth, cash flow from operations, together with other
available sources of funds including borrowings under the Revolving Facility,
will be adequate to make required payments of principal and interest on the
Company's indebtedness and to fund anticipated capital expenditures and
working capital requirements. However, actual capital requirements may change.
The ability of the Company to meet its debt service obligations and reduce its
total debt will be dependent on the future performance of the Company, which
in turn, will be subject to general economic conditions and to financial,
business, and other factors, including factors beyond the Company's control. A
portion of the Company's debt bears interest at floating rates; therefore, its
financial condition is and will continue to be affected by changes in
prevailing interest rates.
 
CHANGES IN ACCOUNTING STANDARDS
  In March, 1995, the Financial Accounting Standards Board issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of," which is effective for fiscal years beginning after
December 15, 1995. The adoption of this standard did not have any effect on
the Company's consolidated results of operations or its financial condition.
 
  In 1993, the Company adopted SFAS No. 112, "Employers' Accounting for
Postemployment Benefits," and recorded a one-time noncash charge of $1.8
million for the prior years' cumulative effect of the accounting change.
Earnings before the cumulative effect of the accounting change were $29.8
million.
 
OTHER MATTERS
  As of December 31, 1995, the Company reduced the discount rate used to
measure the obligations for its pension and other postretirement benefit plans
from 8.5% to 7.0%, in recognition of lower prevailing long-term interest
rates. The effect of the discount rate change on 1996 pension and other
postretirement benefit costs is not material. In connection with the
Transactions, the Company will discontinue its participation in TRW's defined
benefit pension plan during 1996. In addition, in connection with the
Transactions, TRW will retain all liabilities relating to pension and other
post-retirement plans earned through the Closing Date.
 
  Any statements set forth which are not historical facts are forward looking
statements that involve certain risks and uncertainties that could cause
actual results to differ materially from those in the forward looking
statements. Potential risks and uncertainties include such factors as the
substantial leverage and debt service obligation of the Company as a result of
the Transactions, the demand for the Company's products and services,
government regulations and privacy issues, competition, risk of data center
failure, intellectual property rights and other risks identified herein.

OVERVIEW
 
  The Company is a leading provider of credit, marketing and real estate
information on individuals, businesses and properties in the United States.
The Company's products and services play a key role in financial risk
management as well as customer identification, acquisition and retention for
businesses in a wide range of industries including financial services, retail,
real estate, telecommunications and utilities. For the latest twelve-month
period ended March 31, 1996, the Company generated sales of $550.2 million and
pro forma EBITDA (as defined) of approximately $176.7 million. Increased
demand for the Company's core products and expanded applications for reliable
credit and marketing information have contributed to the Company's growth and
profitability.
 
  Over the last 25 years, the Company has developed expertise in collecting,
screening and organizing volumes of data into its five proprietary Databases.
The Databases--consumer credit, business credit, consumer demographic,
business marketing and real estate--contain information on over 190 million
people, 93% of households and 12 million businesses in the United States. The
Company updates the Databases with an average of over 40 million pieces of
information daily from credit grantors, public records and proprietary
sources. Management believes that the Databases represent the broadest and
most current collection of such information in the United States. The Company
utilizes the Databases to create a variety of products and services designed
to address the information needs of its customers and continually seeks to
improve the quality and breadth of its product offerings. In [    ] 1996, the
Company will implement File One, a new relational database system, for its
consumer credit database which the Company believes (among other benefits)
will enhance and expedite product development in a cost-effective manner.
 
INDUSTRY BACKGROUND
 
Credit Information Industry
 
  Credit information products and services are critical to issuers of credit
because they identify credit extension risks and provide a cost effective
method of monitoring outstanding pools of credit. The ability to select
creditworthy customers and extend the proper amount of credit to such
customers is a key determinant of profitability to issuers of credit. The cost
to a credit grantor of purchasing credit information is modest compared to the
potential losses from a bad credit decision. Likewise, timely and accurate
credit information on trading partners enables businesses to maximize revenue
opportunities while minimizing bad debt expense and to improve and more
accurately predict debt collection.
 
  The credit reporting industry has enjoyed strong historic growth. Marketdata
Enterprises estimates the consumer credit reporting industry has grown from
approximately $1.37 billion in revenues in 1992 to approximately $1.63 billion
in revenues in 1995, a compound annual growth rate of 5.9%. Management
believes that the portion of such market in which the Company competes was
approximately $875 million in revenues in 1995. Furthermore, Marketdata
Enterprises estimates the business credit reporting industry has grown from
approximately $920 million in revenues in 1992 to approximately $1 billion in
revenues in 1995, a compound annual growth rate of 2.8%. Management believes
that the portion of such market in which the Company competes was
approximately $600 million in revenues in 1995.
 
  The demand for credit information has been driven by a number of factors,
including growth in consumer credit and the number of cashless transactions,
expanding applications for and the development of new credit products, the
increasing importance of credit portfolio monitoring, and the need for quality
small business credit information. The Company also expects these to be the
principal factors affecting future growth in the credit information industry.
 
                                      45
<PAGE>
 
  Growth in consumer credit and cashless transactions increases the number of
transactions which require issuers to utilize credit information. The increase
in the number of people who carry credit cards, the average number of credit
cards per person and the average utilization of each card are indicative of
this trend. In addition, management estimates that every mortgage application
generates demand for two or three credit reports.
 
  Expanding applications for credit information products and services have
also favorably affected demand. In many industries, businesses are
experiencing an increasing need to invest in their customer base, which makes
the need for sound credit decisions a more important component of
profitability. As an example, growth in wireless telecommunications, including
cellular phones, paging and personal communications services, has created
substantial customer acquisition costs and exposure to large monthly bills,
which have caused telecommunications providers to use credit information more
extensively to manage their businesses. Furthermore, as financial institutions
and retailers more frequently grant "instant" credit as a means of cross-
selling products or acquiring new customers, the need for credit information
increases.
 
  In addition, the development of new, value-added credit information products
and the availability of more complete data have made these products and
services more valuable to existing and prospective customers. The declining
cost of providing credit information has stimulated usage by increasing its
cost effectiveness and accessibility to existing users.
 
  Portfolio monitoring represents a growing and predictable source of demand
for credit information. As the aggregate outstanding consumer credit and
business loans have become a larger portion of business for financial
institutions, retailers and other users, the need to test outstanding credit
portfolios has become more important, particularly in deteriorating credit
environments. Early discovery of a potential credit problem can substantially
reduce a business' overall bad debt expense.
 
  Finally, the increasing number of small businesses and home offices in the
economy have stimulated demand for credit information as well. These entities
represent greater credit risks with less availability of information from
sources other than the credit reporting industry. In addition, consumer credit
has become an important part of the small business credit decision process,
since both a proprietor's business and consumer credit information are often
required to evaluate the risk of extending credit to small enterprises.
 
Marketing Information Industry
 
  Marketing information products and services enable businesses to identify,
retain and cross-sell new and existing customers in a targeted, cost-effective
manner. Through the development and enhancement of customer lists and other
analytical tools based on demographic, lifestyle and behavioral information,
businesses can channel resources toward groups of consumers and businesses
more likely to have a pointed interest in the products and services that they
are offering for sale. Businesses can thereby improve their return on
marketing investments by generating higher response rates from new or
prospective customers.
 
  Several factors are contributing to the growth of the marketing information
industry. The principal driver of growth is the trend away from more costly,
less efficient mass marketing techniques, such as newspaper advertising and
mass mailings, toward micro-marketing techniques, including using information
about existing customers to stimulate additional purchases or using
demographic data for more cost effective identification and acquisition of
potential customers.
 
  Improvements in technological capabilities and data availability have also
contributed to the growth of the marketing information industry. More
powerful, lower cost computer processing has facilitated the development of
more sophisticated databases. Better sources of information have resulted in
increasingly broad and accurate databases with more demographic and lifestyle
 
                                      46
<PAGE>
 
characteristics. More powerful software and other analytical tools enable
users to access the data in a more precise manner. These improvements have
expanded the applications available for existing users of marketing
information and stimulated usage among businesses and in industries which had
previously not considered its capabilities.
 
  Finally, the development and proliferation of non-store distribution formats
(including direct mail, telemarketing and electronic commerce), and the
emergence of pre-approved offers of credit as a way to attract new credit card
customers and encourage switching from competitors' cards have also enhanced
growth in the use of marketing information.
 
  The Company believes it is the largest provider of targeted prescreen
services in North America, an industry which the Company believes had revenues
of approximately $200 million in 1995, and which has grown at a compound
annual growth rate of 39% since 1992. According to a 1995 study, commissioned
by the Direct Marketing Association, total direct marketing advertising
expenditures in the United States in 1995 were estimated to be $134 billion,
up from $101 billion in 1990. Of the total for 1995, total direct mail related
expenditures were estimated to be approximately $31 billion in 1995, up from
approximately $23 billion in 1990. Management believes that the portion of the
market in which the Company competes was approximately $5.0 billion in 1995.
 
Real Estate Information Industry
 
  Real estate information products and services provide appraisers, realtors,
lenders, government agencies and title companies with property data and title
and tax information necessary for the property transfer and financing process.
Property data products and services provide customized reports detailing
property ownership, physical characteristics (such as lot size and dwelling
square footage) and comparable sales activity in a given area. Title companies
rely on title and tax information as a principal information source in the
evaluation of title integrity and tax liens.
 
  Demand for real estate information products and services is principally
driven by automation of the property transfer and financing process, new and
existing home sales activity, commercial property transfers and mortgage
financings and re-financings. Delivery methods for property data in particular
have been shifting from microfiche to CD ROM and on-line products.
 
OPERATING STRENGTHS
 
  The Company believes that it can leverage its strengths to capitalize on
continuing growth in fundamental demand for credit and marketing information.
The Company's operating strengths include the following:
 
Unique Collection of Proprietary Databases
 
  Over the last 25 years, the Company has developed and maintained a unique
collection of five proprietary databases which the Company utilizes to create
a variety of products and services. These Databases--consumer credit, business
credit, consumer demographic, business marketing and real estate--contain
information on over 190 million people, 93% of households and 12 million
businesses in the United States, as well as detailed property data for 349
counties nationwide and property title and tax information for 80 counties in
eight Western states, representing approximately 55% and 17%, respectively, of
the U.S. population. Management believes that its Databases represent the
broadest and most current collection of such information in the U.S. In
addition to name, address, telephone number and credit history, the types of
information in the Databases include numerous demographic and lifestyle
characteristics relating to individuals, households and businesses, such as
age, length of residence at a particular address, dwelling unit type, gender
of the head of household, family composition, estimated household income and
home ownership. Since none of the Company's competitors possesses such a broad
range of databases, the Company has the unique ability to combine elements,
subject to applicable legal constraints, across the Databases to meet the
information needs of existing and potential customers.
 
                                      47
<PAGE>
 
Extensive Database Expertise
 
  Over the last 25 years, the Company has developed extensive capabilities in
building, integrating, managing and utilizing large and complex transaction
oriented databases. The Company obtains data from a variety of proprietary and
publicly available sources, including credit grantors, bankruptcy courts, UCC
filings, driver's licenses, motor vehicle registrations, public real estate
records, U.S. census and postal data, telephone directories and warranty
cards. The Company updates the Databases with an average of over 40 million
pieces of information daily to ensure accuracy and timeliness. The Company
continues to package successfully the information contained in the Databases
to meet the changing demands of its clients. The Company expects that the new
relational architecture of its consumer credit database to be implemented in
[  ] 1996 will enhance the speed, ease and flexibility of searching, sorting,
linking and formatting information and, thereby, the data quality and
effectiveness of product development efforts.
 
  The Allen Data Center employs highly automated advanced technology and a
team of technical professionals to manage its database requirements. The Allen
Data Center has 2,200 million instructions per second (MIPs) of central
processing unit capacity, uses 12 terabytes of direct access storage capacity
and currently operates 7 days a week, 24 hours a day. The Allen Data Center
can process 50 transactions per second with a 2-second response time for each
complex database query. A recent study of 200 large data centers conducted by
the Gartner Group ranks the Allen Data Center second in overall operating
efficiency.
 
Leading Market Positions
 
  The Company has established strong positions in each of its markets and
sells its products to virtually all major credit issuers. The Company is one
of the two largest United States providers of consumer credit information in a
market with only two other national competitors. Also, the Company is the
second largest provider of business credit information in the United States.
The Company believes it is the largest provider of prescreen services and
among the largest providers of other targeted marketing information services.
The Company believes that its 1995 real estate information net sales were
twice as large as the sales of its nearest competitor. The Company's strong
market positions provide the critical mass and economies of scale necessary to
service its customers effectively and to sustain profitable growth.
 
Large Base of Established Customers and Comprehensive Network of Sales
Channels
 
  The Company has built its business around its strong, long-standing customer
relationships in a variety of industries. The Company has had a continuing
business relationship with substantially all of its top 25 customers for over
a decade, or since their inception, and has sold to several of its customers
over much longer periods. The Company believes that relationships with its
customers are the core of its franchise. Major credit information customers
include the nation's largest banks, financial institutions, retailers,
telecommunications companies and utilities.
 
  The Company markets its products and services through a combination of
channels, including its commission-based direct sales force of over 500
people, indirect sales representatives, credit bureaus and its telesales and
teleservicing center. The Company's direct sales force emphasizes a
consultative selling approach for its larger customers. In addition, the
Company services smaller customers through its telemarketing facility and
through local resellers and credit bureaus. The Company believes it sells a
higher percentage of its consumer credit products through Company salespeople
than either of the Company's national competitors. This strategy provides the
Company with closer customer contact, enabling better identification of their
information needs and market trends. The Company's business credit and
marketing services are sold through a direct sales force organized by
industry, since customers within the same industry often require similar types
of products and customer service. This network of channels and practice of
organizing its sales force by industry enhances the Company's ability to
identify emerging customer needs and expand its marketing efforts into new
markets.

Reputation for Integrity, Quality and Reliability
 
  The Company believes it is an industry leader in the handling of sensitive
information in its Databases and the quality and reliability of its products
and services. The Company believes it has been at the forefront of the
industry in terms of compliance with the regulations that affect its business,
including the FCRA and state regulations. The Company strives to treat
consumers fairly and efficiently, including utilization of its state of the
art National Consumer Assistance Center to service consumer inquiries and
complaints. The Company has implemented numerous compliance programs and
partners with, and assists, its key customers in dealing with and educating
their consumer customers.
 
Experienced Management Team and Employees
 
  The Company believes it has been successful in attracting and retaining
qualified management, sales and technical personnel with extensive experience
in the information industry. The Company's sales force maintains long-standing
relationships with the Company's national clients and brings to those clients
knowledge of their industries and of the Company's products and services. The
Company's group of over 400 technical employees (programmers, system engineers
and system analysts) has enabled the development of proprietary database
management software for internal use, as well as software applications for
license to clients for their own credit and marketing analysis. The Company's
top 10 managers have an average of over 10 years of experience with the
Company and its information business predecessors. The Company believes its
ability to attract and retain key people will be further enhanced as an
independent company focused exclusively on the information services industry.
 
OPERATING STRATEGY
 
  The Company has developed a customer-focused operating strategy to
capitalize on its strengths, the growing demand and expanding applications for
its products and economies of scale in the information services industry. The
key elements of this strategy include the following:
 
Maintain, Expand and Enhance the Databases
 
  The Company plans to continue strengthening its core business by acquiring
and developing new types and sources of data, investing in the Databases and
developing new ways to screen information to maintain the breadth and quality
of the Company's database content. Recent examples include the addition of
automotive data to the consumer marketing database and the creation of
personal identification numbers (PIN's) to relate each piece of data in the
consumer credit database to a particular individual and thereby decrease the
likelihood of duplicate records.
 
Develop New Products and Enter Growing End-Use Markets
 
  The Company intends to continue to utilize the Databases to develop value-
added products and services for its customers. In recent years, the Company
has successfully introduced new products across its business. The Company
intends to generate additional growth through the introduction of products
that address a broader range of its customers' credit decisions, products
developed through further integration of the Databases and products that
utilize new information sources such as automotive registration records and
expanded marketing and demographic information. The Company intends to
introduce industry-specialized products, such as new products for the
automotive industry.
 
  The Company is focused on continuing the development of new products and
services to serve the needs of new and growing markets for credit, marketing
and real estate information. The demand for credit and marketing information
continues to expand in conjunction with the development of new industries as
well as the evolution of marketing and distribution methods in many other
industries. For example, growth in the cellular phone industry has resulted in
significant credit exposure for telecommunications companies, and the
Company's revenues from sales to telecommunications
 
                                      49

companies have doubled in the last three years. Additional new market
opportunities include small business markets, automotive information,
insurance underwriting, asset securitization, automated mortgage lending and
healthcare information services.
 
Exploit New Delivery Systems for its Products
 
  As a provider of information content and analytical tools, the Company
continually seeks new ways to package and deliver its products and services to
its customers. Different delivery systems can stimulate usage by existing
customers and make the Company's products and services accessible to new
customers. Currently, the Company delivers a substantial portion of its
products through on-line links between mainframe computers and, to a lesser
extent, on paper and microfiche. Recently, the Company has begun to enhance
its delivery alternatives through the addition of CD ROM and the ability to
download to customer client server networks. In addition, the Company is
developing ways to enhance the accessability of its content through the
Internet and other data networks. The Company plans to expand its distribution
methods as new technologies emerge.
 
Improve Operating Efficiencies
 
  As a result of the Recapitalization, the Company will operate as a stand-
alone entity for the first time. Management has identified approximately $16.6
million of future cost reductions in excess of 1995 historical cost levels,
primarily resulting from operating as an independent corporate entity. For
example, the Company believes a significant portion of the expenses associated
with the development and implementation of File One will be eliminated upon
the completion of the integration period by the end of 1996.
 
Pursue Strategic Acquisitions and Alliances
 
  The Company intends to pursue strategic acquisitions of or alliances with
companies that have products and services, technologies or industry
specializations that enhance or complement those of the Company. In
particular, the Company believes that the domestic marketing information
industry is consolidating and that this trend will continue as economies of
scale become more significant. The Company will also pursue opportunities to
enter the credit reporting and marketing information industries in foreign
markets through acquisitions of, or partnerships with, established businesses.
The Company intends to pursue alliances and joint ventures as a cost-effective
method of offering its products and services in selected markets.
 
PRODUCTS AND SERVICES
 
Credit Information -- Products and Services
 
  The Company's credit information products and services are critical to
issuers of credit because they identify credit extension risks as well as
provide a cost effective method of monitoring outstanding credit portfolios.
The Company's customers use its consumer and business credit products and
services in a variety of applications including the issuance and monitoring of
credit cards, lines of consumer credit, mortgages, small business loans and
trade credit. These products include credit profile reports, credit scoring
services, customized account management, on-line support for instant credit
decisions, accounts receivable evaluations and fraud detection.
 
  Utilizing its proprietary consumer credit database, the Company provides up-
to-date consumer credit reports to various businesses, including banks,
retailers, consumer finance companies, credit unions, mortgage lenders,
utilities and telecommunications companies. The Company also provides other
credit decision support, portfolio management tools and fraud detection
services. For example, the Company offers products that provide ongoing
monitoring of a customer's portfolio of credit accounts for the occurrence of
delinquency and provide proactive assistance in finding delinquent customers.
Also, the Company provides various generic, industry specific, or custom
portfolio analysis models that enable its customers to evaluate, predict and
control consumer credit risks.
 
 
                                      50
<PAGE>
 
  The Company capitalizes on its ability to link its various databases to
provide fully integrated information products to its customers. The Company is
able to market unique business credit products to the fast-growing small
business lending market by drawing information from its consumer and business
databases. For example, the Company offers products that provide credit
information on business proprietors as a complement to credit information
provided on the businesses themselves. The Company also offers industry
specific business profiles containing special data relevant to credit issuers
with business customers in the health care, computer sales, governmental
contracting or nursing homes industries.
 
  The Company's credit products and services are grouped into three major
categories: (i) Credit Verification; (ii) Analytic and Risk Scoring; and (iii)
Other Integrated Offerings. Major products in each category include:

Marketing Information--Products and Services
 
  Marketing information products and services enable businesses to
successfully identify, retain and cross-sell both new and existing customers
in a targeted, cost-effective manner. The Company works
 
                                      51
<PAGE>
 
with its customers throughout the marketing process, from planning and project
design, to list enhancement, database creation and response analysis.
Financial institutions, retailers and other issuers of credit (including major
credit cards, gas cards and phone cards) utilize pre-screened lists of
potential customers to extend offers of pre-approved credit. Catalog mailers,
retailers, financial institutions, consumer products companies,
telecommunications providers and other direct marketers use the Company's
other marketing information products for list development, list enhancements
and creation of marketing databases and other analytical tools.
 
  The Company draws on its extensive credit and demographic information on
over 190 million people and 93% of the households in the United States to
provide relevant consumer information to target marketers of pre-approved
offers of credit. The primary credit marketing information product offering is
prescreened lists, which are targeted lists of customers for credit card or
loan solicitations that meet the credit issuer's predetermined criteria.
Prescreened credit marketing programs can be more effective than random
solicitations and result in higher response levels and therefore lower
customer acquisition costs. Regulations limit the Company's ability to sell
consumer credit data for marketing purposes other than the creation of
prescreened lists of pre-approved credit customers. The use of business credit
information is not as extensively regulated as consumer credit information,
allowing the Company more flexibility in providing business-to-business
products that link business credit data with marketing information.
 
  The Company utilizes its demographic and real estate databases, enhanced by
the non-restricted data (primarily name, address, telephone number and social
security number) in its credit databases, to develop and sell target marketing
products and services. These non-credit based marketing information products
and services include (i) the development of lists of potential customers based
on specified criteria such as behavioral and lifestyle information, purchasing
patterns and other demographic information; (ii) value-added enhancements to
existing customer lists, including elimination of duplicate names, address
correction, appendage of demographic data and sorting by specified criteria;
and (iii) the creation of marketing databases and other tools which companies
can use to analyze customer information and behavior. For example, the Company
can help businesses to create a profile of their target customer by analyzing
and identifying common lifestyle and behavioral characteristics across their
existing customer base. The Company can then search its Databases to develop a
list of individuals and/or businesses who should have the highest propensity
to purchase specified goods and services.

Real Estate Information--Products and Services
 
  Real estate information products and services provide appraisers, realtors,
lenders, government agencies and title companies with property, title and tax
information necessary for the property transfer and financing process. The
Company's property data services also provide customized reports detailing all
residential, commercial and industrial activity in a given area. Title
companies access the Company's title information services on-line as one of
their principal information sources in their evaluation of the condition of
titles for properties being transferred or financed. The Company is the
national leader in both property data and title information services.
 
  The Company provides information, through license agreements with both end
users and re-marketers, to direct marketers, government agencies, law firms,
insurance companies, mortgage securities firms, tax service companies and
others regarding the names and addresses of new home-owners, refinancing and
equity borrowers. Included in this information is real property sales price,
loan-to-value ratio, tax and title data recorded by various governmental
agencies and lender's name. These license agreements relate primarily to
property data and to a lesser extent to title information.
 
  The real estate products are delivered over multiple media, including print,
microfiche, CD ROM and on-line services. In addition to basic property
description reports, the Company offers maps of parcels of land (available in
all media), market research on trends in real estate values and lending
activity, and a home price index that includes predicted and historical real
estate values. In addition to the basic title review products, the Company has
developed a product which simplifies the title review process by storing
images of all title documents and making them available on-line as opposed to
having a reviewer search for these documents on microfiche.

COMPETITION
 
  The Company faces different competitive dynamics in each of its product
areas. The Company, Equifax, Inc. and Trans Union Corp. are the only national
service providers in the consumer credit reporting industry. There are also
numerous small local bureaus in the consumer credit field. The Company's
products compete in the marketplace on the basis of quality of information,
price and customer service. In the business credit marketplace, the Company's
primary, and only national, competitor is Dun & Bradstreet Corp. The Company
competes in the business credit area largely on the basis of quality of data,
integrity and objectivity of data sources and the Company's ability to link
information on small businesses and their proprietors from the business and
consumer credit Databases. The Company competes in the consumer marketing and
business marketing information industries with several large national
companies and smaller regional providers. The Company's national competitors
include Acxiom Corporation, Database America Information Services, Inc.,
Direct Marketing Technology, Inc., Donnelley Marketing, Inc., Equifax, Inc.,
Harte-Hanks Communications, May & Speh, Inc., Metromail Corporation, Neodata
Services, Inc., R.L. Polk & Co. and Trans Union Corp. The Company's real
estate services compete based on breadth of product offerings, multiple
delivery media and geographic coverage. Generally, the Company's competitors
in the real estate information market provide either property data services or
title information services but not both. Real estate information competitors
include DataQuick Inc. in the property data business and Security Union Title
Insurance Company and MetroScan in the title information services business.
 
SALES AND MARKETING
 
  The Company markets its products and services through different channels
including its direct sales forces, indirect sales representatives and
telemarketing services.
 
  Consumer credit services and consumer marketing services are sold primarily
through a 330 person sales organization that includes a national account sales
force and a regional sales force and through a teleservicing center and
various affiliated credit bureaus.
 
  The Company's business credit services and business information services are
sold through 93 direct sales representatives and 175 indirect sales
representatives. Currently, the direct channel sells to approximately 3,000
business customers and the indirect channel sells to approximately 17,000
business customers. As customers within the same industry often require
similar reports and data, this direct sales force is organized by industry
users, including healthcare, telecommunications, financial services, retail,
consumer goods, electronics, giftware, construction and banking. The Company
believes focusing its sales people by industry will enhance the Company's
ability to identify emerging needs for new products.
 
  Property data services are sold through a commission-based national sales
organization of approximately 80 representatives organized into six regions.
The Company also utilizes telemarketing efforts to attract new customers and
sell additional products to its current customers. The Company's title
information services are marketed by a direct sales force of 10 people.
 
  The primary customers of the Company's credit and marketing information
products and services include financial services organizations, retailers,
collection agencies, utilities, automotive companies, telecommunications
businesses and direct marketers. The principal customers of the Company's real
estate information services are title companies, lenders, real estate firms
and data licensing companies. For the year ended December 31, 1995, no
customer accounted for more than 2% of the Company's sales. The Company's top
25 customers accounted for approximately 28% of 1995 sales.

REGULATORY
 
Regulation of Consumer Products
 
  The Company's consumer credit report and consumer prescreen products are
regulated by the FTC under the provisions of the FCRA. The FCRA was intended
to regulate the activities of consumer reporting agencies and was enacted to
prevent both real and perceived abuses in the business of collecting and
disseminating information on consumers. Since the FCRA was passed in 1970, the
information technology supporting the industry has changed significantly.
   
  The FCRA created a framework for the industry by defining both the scope of
the data subject to regulation and setting forth the permissible uses of such
data. The FCRA defines, among other things, a "consumer report" and a
"consumer reporting agency" and specifies the permissible purposes for
furnishing a consumer report. The FCRA also specifies how long information may
be reported on a consumer report. The FCRA requires consumer reporting
agencies to employ "reasonable" procedures to: (i) limit the furnishing of
consumer reports for impermissible purposes, (ii) avoid obsolescence in a
consumer report and (iii) assure the maximum possible accuracy of such
reports. The FCRA regulates disclosures to governmental agencies and
consumers, specifies procedures for disputing information, specifies charges
for certain disclosures, and sets requirements for the users of consumer
reports and liability for non-compliance. The FCRA provides for recovery by a
consumer in federal or state court of actual damages, costs of the action, and
reasonable attorney's fees for the willful or negligent failure, as well as
punitive damages for a willful failure, of a consumer credit reporting agency
to comply with any requirement of the FCRA. The FTC has the responsibility for
the administrative enforcement of the FCRA, including the authority to issue
cease and desist orders in connection with a method of competition, act or
practice determined by the FTC to be unfair or deceptive.     
 
  The consumer credit reporting industry is also regulated by many state
credit reporting statutes. The state statutes typically regulate the
activities of credit reporting agencies in much the same way as the FCRA, but
impose different specific requirements.
 
  The Company is subject to two consent decrees, one with the FTC and one with
eighteen individual states, pursuant to which the Company has agreed to comply
with the FCRA and applicable state regulations and report certain information
to the FTC and such states in connection with the Company's compliance
activities. This reporting requirement expires at the end of 1996. Also, the
Company has agreed to use only identifying information--name, address,
telephone number, social security number, age and gender--from its consumer
credit database for marketing purposes other than prescreen marketing
services. The Company is also subject to two Assurances of Discontinuance with
the State of Vermont whereby the Company is required to compensate consumers
for losses relating to a particular incident as well as to maintain listings
in certain Vermont phone books. The Company has satisfied its compensation
requirements to consumers and is satisfying such phone book listing
requirements.
 
Self Regulation
 
  In response to growing concerns about individual privacy and the collection,
distribution and use of information about individuals, the Direct Marketing
Association (the "DMA"), which is the leading trade association of direct
marketers, has established certain guidelines for fair information practices
which it recommends be followed by participants in the direct marketing
industry. In addition to its compliance with the DMA guidelines, the Company
has adopted and implemented fair information practices, principles and
procedures which supplement those of the DMA. One of the guidelines suggested
by the DMA is that direct marketers refrain from soliciting by mail or
telephone those individuals who have contacted the DMA and have asked that
they not be the subject of unrequested solicitations. To make compliance with
this guideline possible, the DMA maintains the Mail Preference Service and the
Telephone Preference Service, consisting of lists of those individuals who
have notified the DMA that they wish to "opt out" of receiving mail or
telephone solicitations. The DMA makes these lists available to participants
in the direct marketing industry who subscribe to these services. The Company
is a subscriber and receives updated lists from the DMA monthly and promptly
removes from its database all information concerning the individuals who
appear on the DMA lists.
 
Other Regulation
 
  Growing privacy concerns have also led to increased federal and state
regulation of the collection, use and transfer of information about
individuals and of direct marketers and their activities. Examples
 
                                      55
<PAGE>
 
of laws regulating the use of information include laws adopted by a number of
states precluding the use of voter registration and driver's license
information and the federal Driver's Privacy Protection Act of 1994, which
becomes effective in 1997. Under this Act, each state will be prohibited from
disclosing personal information contained in motor vehicle department records
for bulk use in surveys, marketing or solicitations, unless the state has
implemented a procedure whereby each driver has the opportunity to prohibit
such use of information about such driver. Examples of laws regulating direct
marketers and their activities include: state laws requiring telemarketers to
be bonded or registered; an FTC regulation prohibiting certain telemarketing
practices and solicitations; and federal and state restrictions on the use by
telemarketers of automatic dialing and artificial voices or prerecorded
messages. Some of the activities of the Company may be subject to the Real
Estate Settlement Procedures Act which regulates activities in connection with
real estate transactions.
 
Compliance Activities
 
  The Company has adopted a policy of vigorously pursuing individual consumer
and compliance issues, handling them as promptly and unambiguously as
possible. For example, the Company has made a significant investment in its
National Consumer Assistance Center to promptly resolve consumer issues as a
key component of its commitment to compliance and customer service. Also, the
Company has pursued a comprehensive program of compliance and consumer
education activities. Such activities include the Company's: (i) comprehensive
employee training and education program; (ii) system of compliance officers
for its consumer credit business; (iii) advice and oversight by the law
department; (iv) formal adoption of Fair Information Practices and Privacy
Principles; (v) establishment of the Consumer Advisory Council; and (vi) an
ongoing communication program geared towards education of the consumer.
 
INFORMATION TECHNOLOGIES
 
Allen Data Center
 
  The Company operates an information center in Allen, Texas. The Allen Data
Center incorporates state of the art technology with approximately 2,200
million instructions per second ("MIPS") of processing capacity and over 12
terabytes of direct access storage device ("DASD"--disk) storage capacity. The
advanced technology in the Allen Data Center supports 99.7% on-line system
availability. The Allen Data Center operates 7 days a week, 24 hours a day,
and encompasses 45,000 square feet of floor space. The major hardware systems
currently installed in the Allen Data Center include four Amdahl MVS/CICS
mainframe CPU's, 368 tape cartridge drives and 12 tape silos. The Company's
consumer credit database is among the largest transaction-oriented (as opposed
to archival) databases in the world, consisting of over 190 million consumer
credit records with an average of 10 trade lines per record. The Company has
built significant in-house software and hardware expertise related to the
management and manipulation of large, complex databases. Substantially all of
the Company's computer equipment and data operations are located at the Allen
Data Center. See "Risk Factors--Risk of Data Center Failure."
 
  A recent study conducted by the Gartner Group ranked the Allen Data Center
second in cost efficiency among the population of data centers it studied.
According to the study, the Allen Data Center has a low weighted average cost
per unit of data processing work, ranking it in the top 2% of all data centers
in the Gartner Group sample. In addition, the Allen Data Center produces more
customer work per MIPS than all comparison groups in the Gartner Group study.
 
File One
 
  In [    ] 1996, the Company will complete File One, a systems upgrade which
converts its consumer credit database from a flat file to a relational
database architecture. File One is structured to link as much relevant
information and as many differing versions of the same information (such as
duplicate records, social security numbers with transposed digits or name
misspellings) as possible to
 
                                      56
<PAGE>
 
each individual in the Company's consumer credit database with a unique
personal identification number. The linkages in this data structure are
designed to create more flexible methods of search and retrieval of
information by finding individuals in the consumer credit database faster and
more consistently. The Company initiated this upgrade in 1992 and as of
December 31, 1995 has spent approximately $61 million on the development and
implementation of File One over that time period (approximately $40 million of
which has been expensed and $21 million capitalized). The Company expects to
spend approximately $36 million on the implementation of File One in 1996. The
Company does not expect to need to develop or implement another upgrade of
this magnitude in the foreseeable future.
 
  Management believes that the Company has been a leader in the consumer
credit information industry prior to the implementation of File One with
respect to technology and data quality. The Company believes, however, that
File One should provide a number of significant benefits. File One is expected
to enhance the quality of data content, simplify the expansion and addition of
new categories of information and facilitate the association of information in
new ways both within the consumer credit database as well as with the other
Databases. In particular, the Company expects that File One should enable it
to develop new products that respond to changing customer requirements more
quickly and cost effectively.
 
National Network
 
  The Company's nationwide communications network is among the most advanced
in the country. It is a multi-layered, multi-protocol network. The Company's
Central Transport Network ("CTN") connects communication facilities in 13
cities throughout the United States and carries data, voice and video. This
network provides total redundancy for access to the Allen Data Center and is
part of an AT&T service (SecureNet) that guarantees automatic data switching
in the event of a fault. In addition to the CTN, the Company utilizes
CompuServe, IBM and Tymnet public networks for customer access from anywhere
in the United States. The use of the CTN and its technology allows for
significant cost reductions as well as improved reliability.
 
National Consumer Assistance Center
 
  The Company has invested significant resources in the establishment of its
National Consumer Assistance Center (the "NCAC") located in Allen, Texas to
support its consumer credit products and services. The Company has pioneered
the concept of automated, centralized national consumer assistance. The NCAC's
staff of over 400 consumer relations specialists provides consumers with
timely and professional assistance on issues to assist consumers in
understanding the information contained in their credit report and correcting
errors, if any, in the report.
 
  The NCAC staff handles over 8,000 telephone calls and 11,500 pieces of mail
each day. Management ensures a high level of performance by implementing
strong activity measurements and high standards for its associates in areas
including, among others, the number of calls answered in less than three
rings, average hold time and average number of days required to resolve
consumer disputes.
 
  The Company believes that the NCAC provides it with a valuable capability by
facilitating a three-way partnership among the Company, its customers, and
consumers to maintain the integrity and accuracy of the information contained
in the consumer credit files, thereby enhancing both the customer's ability to
make accurate and timely credit granting decisions and the consumer's access
to credit.
 
PROPRIETARY INFORMATION
 
  The Company's success is in large part dependent upon its proprietary
information and technology. The Company relies on a combination of copyright,
trade secret and contract protection to establish and protect its proprietary
rights in its products and technology. The Company generally
 
                                      57
<PAGE>
 
enters into confidentiality agreements with its management and programming
staff and limits access to and distribution of its proprietary information.
The Company also has implemented a number of procedures and controls designed
to prohibit unauthorized access to the Company's computerized databases. There
can be no assurance that the steps taken by the Company in this regard will be
adequate to deter misappropriation of its proprietary rights or information or
independent third party development of substantially similar products and
technology. Although the Company believes that its products and technology do
not infringe any proprietary rights of others, the growing use of copyrights
and patents to protect proprietary rights has increased the risk that third
parties will increasingly assert claims of infringement in the future.
 
FACILITIES
 
  The Company primarily leases its facilities. The Company's principal
executive offices are located in Orange, California, where the Company leases
a 323,000 square foot facility pursuant to a lease expiring in 2002. The
Company also leases 308,000 square feet of space in Allen, Texas for its Allen
Data Center and the NCAC pursuant to a lease expiring in 2010. The Company
leases a total of 1.2 million square feet of facility space.
 
EMPLOYEES
 
  As of the end of March, 1996, the Company had approximately 3,500 employees,
including approximately 50 officers and managerial employees, 800 employees
engaged in sales and marketing and 400 programmers and engineers. No employees
of the Company are covered by a collective bargaining agreement and management
believes that the Company enjoys a good relationship with employees.
 
LITIGATION
   
  The Company is subject to various claims and legal actions which arise in
the ordinary course of business. The large majority of these claims are
brought by consumers and allege various violations of the FCRA or
corresponding state statutes. The Company does not believe that such claims
and legal actions, individually or in the aggregate, will have a material
adverse effect on the Company.     
   
  Subsequent to the execution of the Recapitalization Agreement, James
Springer ("Springer"), president and founder of McCall Springer, Inc. ("McCall
Springer"), sent letters to Bain, THL and others claiming that Bain, THL and
others have certain legal obligations to McCall Springer in connection with
the Recapitalization. In his letters, Springer claimed that Bain, THL and
others failed, in the context of the Recapitalization, to honor certain
alleged agreements with McCall Springer relating to McCall Springer's earlier
proposal to acquire TRW REDI as a separate entity. In February, 1996, each of
Bain and THL brought suit in the United States District Court for the District
of Massachusetts against McCall Springer seeking a declaratory judgment that
neither Bain nor THL has any obligations to McCall Springer in connection with
the Recapitalization Agreement or the Recapitalization. On April 11, 1996,
Springer and McCall Springer filed a lawsuit, in the Superior Court for the
County of Los Angeles, California naming TRW, TRW Information Systems &
Services Division, TRW REDI, D. Van Skilling, Elsevier, N.V., Experian
Corporation, Bain, THL, Acadia Partners, L.P., and Oak Hill Partners, Inc. The
complaint asserts claims sounding in tort and contract, as well as a claim
under the Uniform Trade Secrets Act. The suit seeks unspecified compensatory
and punitive damages and other equitable relief. McCall Springer has moved to
dismiss or to stay the Bain and THL Massachusetts actions brought in federal
court in favor of the California action brought in state court. Experian does
not expect that a judgment in favor of McCall Springer in the California
action will have a material adverse effect on the Company.

PREFERRED STOCK
   
  In connection with the Recapitalization, a subsidiary of TRW will be issued
two classes of Preferred Stock of Holdings, the Voting Preferred will have
approximately $44.0 million of liquidation value and be convertible at any
time by the holder into 6.45% of the fully-diluted Common Stock of Holdings as
of the Closing Date, and the Non-voting Preferred will have $31.0 million of
liquidation value and be convertible at any time by the holder into 4.55% of
the fully-diluted Common Stock of Holdings as of the Closing Date. As of the
Closing Date, the Voting Preferred will represent 14.62% of the aggregate
voting power of Holdings. Dividends will accrue on each class of Preferred
Stock at a rate of 12% per year for as long as the Preferred Stock is
outstanding, payable, at Holdings option, in cash or equivalent accruals. The
effective conversion price of each class of Preferred Stock will increase on
each payment date in proportion to the accrual of dividends.     
   
  The Preferred Stock will be redeemable (a) by Holdings after two years at
the original issue price and (b) by Holdings upon an initial public offering
of Holdings' equity securities or other sale or upon a merger or a change of
control at 104% of the original issue price until the first anniversary of the
Closing Date and at 100% of the original issue price thereafter. Bain and THL
may not transfer more than 50% of their initial equity ownership in Holdings
to an unaffiliated third party unless a third party makes a bona fide offer to
purchase the Preferred Stock at the original issue price thereof.

                             DESCRIPTION OF NOTES
   
  The Notes will be issued under an indenture (the "Indenture"), to be dated
as of    , 1996 by and between the Company and [     ], as Trustee (the
"Trustee"). A copy of the form of the Indenture has been filed as an exhibit
to the Registration Statement of which this Prospectus is a part. The
following is a summary of the material provisions of the Indenture. It does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, the Trust Indenture Act of 1939, as amended (the "TIA"), and
to all of the provisions of the Indenture, including the definitions of
certain terms therein and those terms made a part of the Indenture by
reference to the TIA as in effect on the date of the Indenture. The
definitions of certain capitalized terms used in the following summary are set
forth below under "Certain Definitions." For purposes of this section,
references to the "Company" include only the Company and not its subsidiaries.
    
  The Notes will be unsecured obligations of the Company, ranking subordinate
in right of payment to all Senior Indebtedness of the Company.
 
  The Notes will be issued in fully registered form only, without coupons, in
denominations of $1,000 and integral multiples thereof. Initially, the Trustee
will act as Paying Agent and Registrar for the Notes. The Notes may be
presented for registration of transfer and exchange at the offices of the
Registrar, which initially will be the Trustee's corporate trust office. The
Company may change any Paying Agent and Registrar without notice to holders of
the Notes (the "Holders"). The Company will pay principal (and premium, if
any) on the Notes at the Trustee's corporate office in New York, New York. At
the Company's option, interest may be paid at the Trustee's corporate trust
office or by check mailed to the registered address of Holders.
 
PRINCIPAL, MATURITY AND INTEREST
   
  The Notes are limited in aggregate principal amount to $250 million and will
mature on    , 2006. Interest on the Notes will accrue at the rate of    % per
annum and will be payable semiannually in cash on each     and    commencing
on    , 1997, to the Persons who are registered Holders at the close of
business on     the     and     immediately preceding the applicable interest
payment date. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date
of issuance.     
 
  The Notes will not be entitled to the benefit of any mandatory sinking fund.

REDEMPTION
 
  Optional Redemption. The Notes will be redeemable, at the Company's option,
in whole at any time or in part from time to time, on and after    , 2001,
upon not less than 30 nor more than 60 days' notice, at the following
redemption prices (expressed as percentages of the principal amount thereof)
if redeemed during the twelve-month period commencing on     of the year set
forth below, plus, in each case, accrued interest to the date of redemption:

  Optional Redemption Upon Equity Offerings. At any time, or from time to
time, on or prior to    , 1999, the Company may, at its option, use the net
cash proceeds of one or more Equity Offerings (as defined below) to redeem up
to 40% of the aggregate principal amount of Notes originally issued at a
redemption price equal to    % of the principal amount thereof plus accrued
interest to the date of redemption; provided that at least $   million of the
original principal amount of Notes remains outstanding immediately after any
such redemption.
 
  In order to effect the foregoing redemption with the proceeds of any Equity
Offering, the Company shall make such redemption not more than 120 days after
the consummation of any such Equity Offering.
 
  As used in the preceding two paragraphs, "Equity Offering" means an offering
of Qualified Capital Stock of Holdings or the Company; provided that, in the
event of an Equity Offering by Holdings, Holdings contributes to the capital
of the Company the portion of the net cash proceeds of such Equity Offering
necessary to pay the aggregate redemption price (plus accrued interest to the
redemption date) of the Notes to be redeemed pursuant to the preceding
paragraph.
 
SELECTION AND NOTICE
 
  In case of a partial redemption, selection of the Notes or portions thereof
for redemption shall be made by the Trustee by lot, pro rata or in such manner
as it shall deem appropriate and fair and in such manner as complies with any
applicable legal requirements; provided, however, that if a partial redemption
is made with the proceeds of an Equity Offering, selection of the Notes or
portion thereof for redemption shall be made by the Trustee only on a pro rata
basis, unless such method is otherwise prohibited. Notes may be redeemed in
part in multiples of $1,000 principal amount only. Notice of redemption will
be sent, by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to each Holder whose Notes
are to be redeemed at the last address for such Holder then shown on the
registry books. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note. On and after any redemption date,
interest will cease to accrue on the Notes or part thereof called for
redemption as long as the Company has deposited with the Paying Agent funds in
satisfaction of the redemption price pursuant to the Indenture.
 
RANKING OF NOTES
 
  The indebtedness evidenced by the Notes will be unsecured Senior
Subordinated Indebtedness of the Company, will be subordinated in right of
payment, as set forth in the Indenture, to all existing
 
                                      67
<PAGE>
 
and future Senior Indebtedness of the Company, will rank pari passu in right
of payment with all existing and future Senior Subordinated Indebtedness of
the Company and will be senior in right of payment to all existing and future
Subordinated Obligations of the Company. The Notes will also be effectively
subordinated to any Secured Indebtedness of the Company to the extent of the
value of the assets securing such Indebtedness, and to all Indebtedness of its
Subsidiaries. However, payment from the money or the proceeds of U.S.
government obligations held in any defeasance trust described under "--Legal
Defeasance and Covenant Defeasance" below is not subordinated to any Senior
Indebtedness or subject to the restrictions described above if the deposit to
such trust which is used to fund such payment was permitted at the time of
such deposit.
   
  As of March 31, 1996, on a pro forma basis, after giving effect to the
Transactions, the Company would have had approximately $561.7 million of
Senior Indebtedness outstanding (excluding unused commitments) all of which
would have been Secured Indebtedness. Although the Indenture contains
limitations on the amount of additional Indebtedness which the Company and its
Restricted Subsidiaries may incur, under certain circumstances the amount of
such Indebtedness could be substantial and, in any case, such Indebtedness may
be Senior Indebtedness or Secured Indebtedness. See "--Certain Covenants--
Limitation on Incurrence of Additional Indebtedness" below.     
 
  Only Indebtedness of the Company that is Senior Indebtedness will rank
senior in right of payment to the Notes in accordance with the provisions of
the Indenture. The Notes will in all respects rank pari passu in right of
payment with all other Senior Subordinated Indebtedness of the Company. The
Company has agreed in the Indenture that it will not incur, directly or
indirectly, any Indebtedness which is expressly subordinate in right of
payment to Senior Indebtedness unless such Indebtedness is Senior Subordinated
Indebtedness or is expressly subordinated in right of payment to Senior
Subordinated Indebtedness. Without limiting the foregoing, unsecured
Indebtedness is not deemed to be subordinate or junior to Secured Indebtedness
merely because it is unsecured.
   
  The Company may not pay principal of, premium (if any) or interest on, or
any other amount in respect of, the Notes or make any deposit pursuant to the
provisions described under "--Legal Defeasance and Covenant Defeasance" below
and may not otherwise purchase, redeem or otherwise retire any Notes
(collectively, "pay the Notes") if (i) any Senior Indebtedness is not paid
when due in cash or Cash Equivalents or (ii) any other default on Senior
Indebtedness occurs and the maturity of such Senior Indebtedness is
accelerated in accordance with its terms unless, in either case, the default
has been cured or waived and any such acceleration has been rescinded or such
Senior Indebtedness has been paid in full in cash or Cash Equivalents.
However, the Company may pay the Notes without regard to the foregoing if the
Company and the Trustee receive written notice approving such payment from the
Representative of the holders of the Designated Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of the
immediately preceding sentence has occurred and is continuing.     
 
  In addition, during the continuance of any default (other than a default
described in clause (i) or (ii) of the first sentence of the immediately
preceding paragraph) with respect to any Designated Senior Indebtedness
pursuant to which the maturity thereof may be accelerated immediately without
further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, the Company
may not pay the Notes for a period (a "Payment Blockage Period") commencing
upon the receipt by the Trustee (with a copy to the Company) of written notice
(a "Blockage Notice") of such default from the Representative of the holders
of such Designated Senior Indebtedness specifying an election to effect a
Payment Blockage Period and ending 179 days thereafter (or earlier if such
Payment Blockage Period is terminated (i) by written notice to the Trustee and
the Company from the Person or Persons who gave such Blockage Notice, (ii)
because the default giving rise to such Blockage Notice is no longer
continuing or (iii) because such Designated Senior Indebtedness has been
repaid in full in cash or Cash Equivalents).
 
 
                                      68
<PAGE>
 
  Notwithstanding the provisions described in the immediately preceding
paragraph, unless any of the events described in clause (i) or (ii) of the
first sentence of the second immediately preceding paragraph is then
occurring, the Company may resume payments on the Notes after the end of such
Payment Blockage Period, including any missed payments. Not more than one
Blockage Notice may be given in any consecutive 360-day period, irrespective
of the number of defaults with respect to Designated Senior Indebtedness
during such period. However, if any Blockage Notice within such 360-day period
is given by or on behalf of any holders of Designated Senior Indebtedness
other than the Bank Indebtedness, a Representative of holders of Bank
Indebtedness may give another Blockage Notice within such period. In no event,
however, may the total number of days during which any Payment Blockage Period
or Periods is in effect exceed 179 days in the aggregate during any 360
consecutive day period.
 
  Upon any payment or distribution of the assets or securities of the Company
upon a total or partial liquidation or dissolution or reorganization of or
similar proceeding relating to the Company or its property or in a bankruptcy,
insolvency, receivership or similar proceeding relating to the Company or its
property, or in an assignment for the benefit of creditors or any marshalling
of the assets and liabilities of the Company, the holders of Senior
Indebtedness will be entitled to receive payment in full in cash or Cash
Equivalents of the Senior Indebtedness before the holders of the Notes are
entitled to receive any payment and, until the Senior Indebtedness is paid in
full in cash or Cash Equivalents, any payment or distribution to which holders
of the Notes would be entitled but for the subordination provisions of the
Indenture will be made to holders of the Senior Indebtedness as their
interests may appear. If a payment or distribution is made to holders of the
Notes that due to the subordination provisions should not have been made to
them, such holders of the Notes are required to hold it in trust for the
holders of Senior Indebtedness and pay it over to them as their interests may
appear.
 
  If payment of the Notes is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness or the Representative of such holders of the acceleration.
The Company may not pay the Notes until five business days after
such holders or the Representative of the holders of Designated Senior
Indebtedness receive notice of such acceleration and, thereafter, may pay the
Notes only if the subordination provisions of the Indenture otherwise permit
payment at that time.
 
  By reason of such subordination provisions contained in the Indenture, in
the event of insolvency, creditors of the Company who are holders of Senior
Indebtedness may recover more, ratably, than the holders of the Notes, and
creditors of the Company who are not holders of Senior Indebtedness or of
Senior Subordinated Indebtedness (including the Notes) may recover less,
ratably, than holders of Senior Indebtedness and may recover more than the
holders of Senior Subordinated Indebtedness.
 
GUARANTEES
 
  After the Issue Date, the Company will cause each Restricted Subsidiary of
the Company that guarantees payment of the Bank Indebtedness (each, a
"Subsidiary Guarantor") to execute and deliver to the Trustee a supplemental
indenture pursuant to which such Restricted Subsidiary will guarantee (each, a
"Guarantee") payment of the Notes. See "Certain Covenants--Future Guarantees."
 
  Each such Subsidiary Guarantor will unconditionally guarantee, on a senior
subordinated basis, jointly and severally, to each Holder and the Trustee, the
full and prompt performance of the Company's obligations under the Indenture
and the Notes, including the payment of principal of and interest on the
Notes. The Guarantees will be subordinated to Guarantor Senior Indebtedness on
the same basis as the Notes are subordinated to Senior Indebtedness. The
obligations of each Subsidiary Guarantor are limited to the maximum amount
which, after giving effect to all other contingent and fixed liabilities of
such Subsidiary Guarantor and after giving effect to any collections from or
payments
 
                                      69
<PAGE>
 
made by or on behalf of any other Subsidiary Guarantor in respect of the
obligations of such other Subsidiary Guarantor under its Guarantee or pursuant
to its contribution obligations under the Indenture, will result in the
obligations of such Subsidiary Guarantor under the Guarantee not constituting
a fraudulent conveyance or fraudulent transfer under federal or state law.
Each Subsidiary Guarantor that makes a payment or distribution under a
Guarantee shall be entitled to a contribution from each other Subsidiary
Guarantor in an amount pro rata, based on the Adjusted Net Assets (as defined
in the Indenture) of each Subsidiary Guarantor.
 
  Each Subsidiary Guarantor may consolidate with or merge into, liquidate,
dissolve or sell its assets to the Company or another Subsidiary Guarantor
that is a Wholly Owned Restricted Subsidiary of the Company without
limitation, or with other Persons upon the terms and conditions set forth in
the Indenture. See "Certain Covenants--Merger, Consolidation and Sale of
Assets." In the event that (i) either all of the Capital Stock of a Subsidiary
Guarantor is sold by the Company (whether by merger, stock purchase or
otherwise) or all or substantially all of the assets of a Subsidiary Guarantor
are sold by such Subsidiary Guarantor and such sale complies with the
provisions set forth in "Certain Covenants--Limitation on Asset Sales" or (ii)
the lenders under the Bank Credit Agreement release a Subsidiary Guarantor of
all guarantees under the Bank Credit Agreement and release all Liens on the
property and assets of such Subsidiary Guarantor relating to the Bank
Indebtedness, then in each case the Subsidiary Guarantor's Guarantee will be
released.
 
CHANGE OF CONTROL
 
  The Indenture will provide that upon the occurrence of a Change of Control
Triggering Event, each Holder will have the right to require that the Company
purchase all or a portion of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer"), at a purchase price equal to
101% of the principal amount thereof plus accrued interest to the date of
purchase.
 
  The Indenture will provide that, prior to the mailing of the notice referred
to below, but in any event within 30 days following any Change of Control
Triggering Event, the Company covenants to (i) repay in full and terminate all
commitments under the Bank Indebtedness or offer to repay in full and
terminate all commitments under all Bank Indebtedness and to repay the Bank
Indebtedness owed to each holder of Bank Indebtedness which has accepted such
offer or (ii) obtain the requisite consents under the Bank Credit Agreement to
permit the repurchase of the Notes as provided below. The Company shall first
comply with the covenant in the immediately preceding sentence before it shall
be required to repurchase Notes pursuant to the provisions described below.
The Company's failure to comply with this covenant shall constitute an Event
of Default described in clause (iii) and not in clause (ii) under "Events of
Default" below.
 
  Within 30 days following the date upon which the Change of Control
Triggering Event occurred, the Company must send, by first class mail, a
notice to each Holder, with a copy to the Trustee, which notice shall govern
the terms of the Change of Control Offer. Such notice shall state, among other
things, the purchase date, which must be no earlier than 30 days nor later
than 45 days from the date such notice is mailed, other than as may be
required by law (the "Change of Control Payment Date"). Holders electing to
have a Note purchased pursuant to a Change of Control Offer will be required
to surrender the Note, with the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Note completed, to the Paying Agent at the
address specified in the notice prior to the close of business on the third
business day prior to the Change of Control Payment Date.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
purchase price for all the Notes that might be delivered by Holders seeking to
accept the Change of Control Offer. In the event the Company is required to
purchase outstanding Notes pursuant to a Change of Control Offer, the Company
expects that it would seek third party financing to the extent it does not
have available funds to meet its purchase obligations. However, there can be
no assurance that the Company would be able to obtain such financing.
 
                                      70
<PAGE>
 
   
  The definition of Change of Control includes a phrase relating to the sale,
lease, exchange or other transfer of "all or substantially all" of the
Company's assets as such phrase is defined in the Revised Model Business
Corporation Act. Although there is a developing body of case law interpreting
the phrase "substantially all," there is no precise definition of the phrase
under applicable law. Accordingly, in certain circumstances there may be a
degree of uncertainty in ascertaining whether a particular transaction would
involve a disposition of "all or substantially all" of the assets of the
Company, and therefore it may be unclear as to whether a Change of Control has
occurred and whether the Holders have the right to require the Company to
repurchase such Notes.     
 
  Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to a Holder's right to redemption upon a Change of Control
Triggering Event. Restrictions in the Indenture described herein on the
ability of the Company and its Restricted Subsidiaries to incur additional
Indebtedness, to grant Liens on their properties, to make Restricted Payments
and to make Asset Sales may also make more difficult or discourage a takeover
of the Company, whether favored or opposed by the management of the Company.
Consummation of any such transaction in certain circumstances may require
redemption or repurchase of the Notes, and there can be no assurance that the
Company or the acquiring party will have sufficient financial resources to
effect such redemption or repurchase. Such restrictions and the restrictions
on transactions with Affiliates may, in certain circumstances, make more
difficult or discourage any leveraged buyout of the Company or any of its
Subsidiaries by the management of the Company. While such restrictions cover a
wide variety of arrangements which have traditionally been used to effect
highly leveraged transactions, the Indenture may not afford the Holders of
Notes protection in all circumstances from the adverse aspects of a highly
leveraged transaction, reorganization, restructuring, merger or similar
transaction.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.
 
CERTAIN COVENANTS
 
  The Indenture contains, among others, the following covenants:
 
  Limitation on Restricted Payments. The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly, (a)
declare or pay any dividend or make any distribution (other than dividends or
distributions payable in Qualified Capital Stock) on or in respect of shares
of Capital Stock of the Company to holders of such Capital Stock, (b)
purchase, redeem or otherwise acquire or retire for value any Capital Stock of
the Company or any warrants, rights or options to purchase or acquire shares
of any class of such Capital Stock, other than the exchange of such Capital
Stock for Qualifield Capital Stock, or (c) make any Investment (other than
Permitted Investments) (each of the foregoing actions set forth in clauses
(a), (b) and (c) being referred to as a "Restricted Payment"), if at the time
of such Restricted Payment or immediately after giving effect thereto, (i) a
Default or an Event of Default shall have occurred and be continuing, (ii) the
Company is not able to incur at least $1.00 of additional Indebtedness (other
than Permitted Indebtedness) in compliance with the "Limitation on Incurrence
of Additional Indebtedness" covenant, or (iii) the aggregate amount of
Restricted Payments made subsequent to the Issue Date shall exceed the sum of:
(w) 50% of the cumulative Consolidated Net Income (or if cumulative
Consolidated Net Income shall be a loss, minus 100% of such loss) of the
Company earned subsequent to the Issue Date and on or prior to the date the
Restricted Payment occurs (the "Reference Date") (treating such period as a
single accounting period); plus (x) 100% of the aggregate net proceeds
received by the Company (including the fair market value of property other
than cash) from any Person (other than a Subsidiary of the Company) from the
issuance and sale subsequent to the Issue Date and on or prior to the
 
                                      71
<PAGE>
 
   
Reference Date of Qualified Capital Stock of the Company (including Capital
Stock issued upon the conversion of convertible Indebtedness or in exchange
for outstanding Indebtedness); plus (y) without duplication of any amounts
included in clause (iii)(x) above, 100% of the aggregate net proceeds
(including the fair market value of property other than cash) of any equity
contribution received by the Company from a holder of the Company's Capital
Stock (excluding any net proceeds from an Equity Offering to the extent used
to redeem Notes in accordance with the optional redemption provisions of the
Notes other than in connection with an Equity Offering pursuant to a
registration statement filed with the Commission in accordance with the
Securities Act); plus (z) to the extent that any Investment (other than a
Permitted Investment) that was made after the Issue Date is sold for cash or
otherwise liquidated or repaid for cash, the lesser of (A) the cash received
with respect to such sale, liquidation or repayment of such Investment (less
the cost of such sale, liquidation or repayment, if any) and (B) the initial
amount of such Investment.     
 
  Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit: (1) the payment of any dividend or the
consummation of any irrevocable redemption within 60 days after the date of
declaration of such dividend or notice of such redemption if the dividend or
payment of the redemption price, as the case may be, would have been permitted
on the date of declaration or notice; (2) if no Event of Default shall have
occurred and be continuing as a consequence thereof, the acquisition of any
shares of Capital Stock of the Company, either (i) solely in exchange for
shares of Qualified Capital Stock of the Company, or (ii) through the
application of net proceeds of a substantially concurrent sale (other than to
a Subsidiary of the Company) of shares of Qualified Capital Stock of the
Company; (3) payments for the purpose of and in an amount equal to the amount
required to permit Holdings to redeem or repurchase Holdings' common equity or
options in respect thereof, in each case in connection with the repurchase
provisions under employee stock option or stock purchase agreements or other
agreements to compensate management employees; provided that such redemptions
or repurchases pursuant to this clause (3) shall not exceed $10 million (which
amount shall be increased by the amount of any proceeds to the Company from
(x) sales of Capital Stock of Holdings to management employees subsequent to
the Issue Date and (y) any "key-man" life insurance policies which are used to
make such redemptions or repurchases) in the aggregate; provided, further,
that the cancellation of Indebtedness owing to the Company from members of
management of the Company or any of its Restricted Subsidiaries in connection
with a repurchase of Capital Stock of Holdings will not be deemed to
constitute a Restricted Payment under the Indenture; (4) the making of
distributions, loans or advances in an amount not to exceed $1 million per
annum sufficient to permit Holdings to pay the ordinary operating expenses of
Holdings (including, without limitation, directors fees, indemnification
obligations, professional fees and expenses) related to Holdings' ownership of
Capital Stock of the Company (other than to the Principals or their Related
Parties); (5) the payment of any amounts pursuant to the Tax Allocation
Agreement; (6) the payment of fees and compensation as permitted under clause
(i) of paragraph (b) of the "Transactions with Affiliates" covenant; (7) so
long as no Default or Event of Default shall have occurred and be continuing,
payments not to exceed $100,000 in the aggregate, to enable Holdings to make
payments to holders of its Capital Stock in lieu of issuance of fractional
shares of its Capital Stock; and (8) repurchases of Capital Stock deemed to
occur upon the exercise of stock options if such Capital Stock represents a
portion of the exercise price thereof. In determining the aggregate amount of
Restricted Payments made subsequent to the Issue Date in accordance with
clause (iii) of the immediately preceding paragraph, (a) amounts expended (to
the extent such expenditure is in the form of cash or other property other
than Qualified Capital Stock) pursuant to clauses (1), (2) and (3) of this
paragraph shall be included in such calculation, provided that such
expenditures pursuant to clause (3) shall not be included to the extent of
cash proceeds received by the Company from any "key man" life insurance
policies and (b) amounts expended pursuant to clause (4), (5), (6), (7) and
(8) shall be excluded from such calculation.
 
  Limitation on Incurrence of Additional Indebtedness. The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume, guarantee, acquire,
 
                                      72
<PAGE>
 
become liable, contingently or otherwise, with respect to, or otherwise become
responsible for payment of (collectively, "incur") any Indebtedness (other
than Permitted Indebtedness); provided, however, that if no Default or Event
of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of any such Indebtedness, the Company or any
Subsidiary Guarantor may incur Indebtedness if on the date of the incurrence
of such Indebtedness, after giving effect to the incurrence thereof, the
Consolidated Fixed Charge Coverage Ratio of the Company is greater than (a)
2.0 to 1.0 if such proposed incurrence of Indebtedness is prior to     , 1999
or (b) 2.25 to 1.0 if such proposed incurrence of Indebtedness is on or after
    , 1999.
 
  Limitations on Transactions with Affiliates.
 
  (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into or permit to exist any
transaction or series of related transactions (including, without limitation,
the purchase, sale, lease or exchange of any property or the rendering of any
service) with, or for the benefit of, any of its Affiliates (an "Affiliate
Transaction"), other than (x) Affiliate Transactions permitted under paragraph
(b) below and (y) Affiliate Transactions on terms that are no less favorable
than those that might reasonably have been obtained in a comparable
transaction at such time on an arm's-length basis from a Person that is not an
Affiliate; provided, however, that for a transaction or series of related
transactions with an aggregate value of $5 million or more, at the Company's
option (i) such determination shall be made in good faith by a majority of the
disinterested members of the Board of the Directors of the Company or (ii) the
Board of Directors of the Company or any such Restricted Subsidiary party to
such Affiliate Transaction shall have received a favorable opinion from a
nationally recognized investment banking firm that such Affiliate Transaction
is on terms not materially less favorable than those that might reasonably
have been obtained in a comparable transaction at such time on an arm's-length
basis from a Person that is not an Affiliate; provided, further, that for a
transaction or series of related transactions with an aggregate value of $10
million or more, the Board of Directors of the Company shall have received a
favorable opinion from a nationally recognized investment banking firm that
such Affiliate Transaction is on terms not materially less favorable than
those that might reasonably have been obtained in a comparable transaction at
such time on an arm's-length basis from a Person that is not an Affiliate.
   
  (b) The foregoing restrictions shall not apply to (i) reasonable fees and
compensation paid to, and indemnity provided on behalf of, officers,
directors, employees or consultants of the Company or any Subsidiary of the
Company as determined in good faith by the Company's Board of Directors or
senior management; (ii) transactions exclusively between or among the Company
and any of its Wholly Owned Restricted Subsidiaries or exclusively between or
among such Wholly Owned Restricted Subsidiaries, provided such transactions
are not otherwise prohibited by the Indenture; (iii) transactions effected as
part of a Qualified Receivables Transaction; (iv) any agreement as in effect
as of the Issue Date or any amendment thereto or any transaction contemplated
thereby (including pursuant to any amendment thereto) in any replacement
agreement thereto so long as any such amendment or replacement agreement is
not more disadvantageous to the Holders in any material respect than the
original agreement as in effect on the Issue Date; and (v) Restricted Payments
permitted by the Indenture.     
 
  Limitation on Liens. The Company will not, and will not permit any of its
Restricted Subsidiaries to, create, incur, assume or suffer to exist any Liens
of any kind against or upon any of its property or assets, or any proceeds
therefrom, unless (i) in the case of Liens securing Indebtedness that is
expressly subordinate or junior in right of payment to the Notes, the Notes
are secured by a Lien on such property, assets or proceeds that is senior in
priority to such Liens and (ii) in all other cases, the Notes are equally and
ratably secured, except for (A) Liens existing as of the Issue Date and any
extensions, renewals or replacements thereof; (B) Liens securing Senior
Indebtedness and Guarantor Senior Indebtedness; (C) Liens securing the Notes
and the Guarantees; (D) Liens of the Company or a Wholly Owned Restricted
Subsidiary on assets of any Subsidiary of the Company; (E) Liens securing
Indebtedness which is incurred to refinance Indebtedness which has been
secured by a Lien permitted
 
                                      73
<PAGE>
 
under the Indenture and which has been incurred in accordance with the
provisions of the Indenture; provided, however, that such Liens do not extend
to or cover any property or assets of the Company or any of its Restricted
Subsidiaries not securing the Indebtedness so refinanced; and (F) Permitted
Liens.
 
  Prohibition on Incurrence of Senior Subordinated Debt. Neither the Company
nor any Subsidiary Guarantor will incur or suffer to exist Indebtedness that
is senior in right of payment to the Notes or such Subsidiary Guarantor's
Guarantee and subordinate in right of payment to any other Indebtedness of the
Company or such Subsidiary Guarantor, as the case may be.
 
  Limitation on Dividend and Other Payment Restrictions Affecting
Subsidiaries. The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or permit
to exist or become effective any encumbrance or restriction on the ability of
any Restricted Subsidiary to (a) pay dividends or make any other distributions
on or in respect of its Capital Stock; (b) make loans or advances or to pay
any Indebtedness or other obligation owed to the Company or any other
Restricted Subsidiary of the Company; or (c) transfer any of its property or
assets to the Company or any other Restricted Subsidiary of the Company,
except for such encumbrances or restrictions existing under or by reason of:
(1) applicable law; (2) the Indenture; (3) non-assignment provisions of any
contract or any lease entered into in the ordinary course of business; (4) any
instrument governing Acquired Indebtedness, which encumbrance or restriction
is not applicable to the Company or any Restricted Subsidiary of the Company,
or the properties or assets of any such Person, other than the Person or the
properties or assets of the Person so acquired; (5) agreements existing on the
Issue Date (including, without limitation, the Bank Credit Agreement); (6)
restrictions on the transfer of assets subject to any Lien permitted under the
Indenture imposed by the holder of such Lien; (7) restrictions imposed by any
agreement to sell assets permitted under the Indenture to any Person pending
the closing of such sale; (8) any agreement or instrument governing Capital
Stock of any Person that is acquired after the Issue Date; (9) Indebtedness or
other contractual requirements of a Receivables Entity in connection with a
Qualified Receivables Transaction; provided that such restrictions apply only
to such Receivables Entity; or (10) an agreement effecting a refinancing,
replacement or substitution of Indebtedness issued, assumed or incurred
pursuant to an agreement referred to in clause (2), (4) or (5) above;
provided, however, that the provisions relating to such encumbrance or
restriction contained in any such refinancing, replacement or substitution
agreement are no less favorable to the Company or the Holders in any material
respect as determined by the Board of Directors of the Company than the
provisions relating to such encumbrance or restriction contained in agreements
referred to in such clause (2), (4) or (5).
 
  Limitation on Preferred Stock of Subsidiaries. The Company will not permit
any of its Restricted Subsidiaries to issue any Preferred Stock (other than to
the Company or to a Wholly Owned Restricted Subsidiary of the Company) or
permit any Person (other than the Company or a Wholly Owned Restricted
Subsidiary of the Company) to own any Preferred Stock of any Restricted
Subsidiary of the Company.
 
  Merger, Consolidation and Sale of Assets. The Company will not, in a single
transaction or a series of related transactions, consolidate with or merge
with or into, or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of its assets to, another Person or Persons unless
(i) either (A) the Company shall be the survivor of such merger or
consolidation or (B) the surviving Person is a corporation existing under the
laws of the United States, any state thereof or the District of Columbia and
such surviving Person shall expressly assume all the obligations of the
Company under the Notes and the Indenture; (ii) immediately after giving
effect to such transaction (on a pro forma basis, including any Indebtedness
incurred or anticipated to be incurred in connection with such transaction and
including adjustments that are (i) directly attributable to such transaciton
and (ii) factually supportable), the Company or the surviving Person is able
to incur at least $1.00 of additional Indebtedness (other than Permitted
Indebtedness) in compliance with the "Limitation on Incurrence of
 
                                      74
<PAGE>
 
   
Additional Indebtedness" covenant; (iii) immediately before and immediately
after giving effect to such transaction (including any Indebtedness incurred
or anticipated to be incurred in connection with the transaction), no Default
or Event of Default shall have occurred and be continuing; (iv) each
Subsidiary Guarantor, unless it is the other party to the transaction, shall
have by supplemental indenture confirmed that after consummation of such
transaction its Guarantee shall apply, as such Guarantee applied on the date
it was granted under the Indenture to the obligations of the Company under the
Indenture and the Notes, to the obligations of the Company or such Person, as
the case may be, under the Indenture and the Notes; and (v) the Company has
delivered to the Trustee an officers' certificate and opinion of counsel, each
stating that such consolidation, merger or transfer complies with the
Indenture, that the surviving Person agrees to be bound thereby, and that all
conditions precedent in the Indenture relating to such transaction have been
satisfied. For purposes of the foregoing, the transfer (by lease, assignment,
sale or otherwise, in a single transaction or series of transactions) of all
or substantially all of the properties and assets of one or more Subsidiaries
of the Company, the Capital Stock of which constitutes all or substantially
all of the properties and assets of the Company, shall be deemed to be the
transfer of all or substantially all of the properties and assets of the
Company. Notwithstanding the foregoing clauses (ii) and (iii) of the preceding
sentence, (a) any Restricted Subsidiary of the Company may consolidate with,
merge into or transfer all or part of its properties and assets to the Company
and (b) the Company may merge with an Affiliate incorporated solely for the
purpose of reincorporating the Company in another jurisdiction.     
 
  The Indenture will provide that upon any consolidation, combination or
merger or any transfer of all or substantially all of the assets of the
Company in accordance with the foregoing, the surviving entity shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under the Indenture and the Notes with the same effect as if such
surviving entity had been named as such; provided that solely for purposes of
computing amounts described in clause (iii) of the first paragraph of the
covenant "Limitation on Restricted Payments" above, any such surviving entity
to the Company shall only be deemed to have succeeded to and be substituted
for the Company with respect to periods subsequent to the effective time of
such merger, consolidation, combination or transfer of assets.
 
  Each Subsidiary Guarantor (other than any Subsidiary Guarantor whose
Guarantee is to be released in accordance with the terms of its Guarantee and
the Indenture in connection with any transaction complying with the provisions
of "--Limitation on Asset Sales" or as otherwise provided in the Indenture)
will not, and the Company will not cause or permit any Subsidiary Guarantor
to, consolidate with or merge with or into any Person other than the Company
or any other Subsidiary Guarantor unless: (i) the entity formed by or
surviving any such consolidation or merger (if other than the Subsidiary
Guarantor) or to which such sale, lease, conveyance or other disposition shall
have been made is a corporation organized and existing under the laws of the
United States or any State thereof or the District of Columbia; (ii) such
entity assumes by supplemental indenture all of the obligations of the
Subsidiary Guarantor on the Guarantee; (iii) immediately after giving effect
to such transaction, no Default or Event of Default shall have occurred and be
continuing; and (iv) immediately after giving effect to such transaction and
the use of any net proceeds therefrom, on a pro forma basis, including
adjustments that are (i) directly attributable to such transaction and (ii)
factually supportable, the Company could satisfy the provisions of clause (ii)
of the first paragraph of this covenant.
 
  Limitation on Asset Sales. The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the
Company or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets sold or otherwise disposed of (as determined in good faith
by the Company's Board of Directors), (ii) at least 75% of the consideration
received by the Company or such Restricted Subsidiary, as the case may be,
from such Asset Sale shall be cash or Cash Equivalents and is received at the
time of such disposition; provided that the amount of (x) any liabilities (as
shown on the Company's or such Restricted Subsidiary's most recent balance
sheet or in the notes thereto)
 
                                      75
<PAGE>
 
of the Company or such Restricted Subsidiary (other than liabilities that are
by their terms subordinated to the Notes or such Restricted Subsidiary's
Guarantee, if any) that are assumed by the transferee of any such assets and
(y) any notes or other obligations received by the Company or any such
Restricted Subsidiary from such transferee that are immediately converted by
the Company or any such Restricted Subsidiary into cash or Cash Equivalents
(to the extent of the cash or Cash Equivalents received) shall be deemed to be
cash for purposes of this provision; and (iii) upon the consummation of an
Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to
apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of
receipt thereof either (A) to prepay any Senior Indebtedness or Guarantor
Senior Indebtedness and, in the case of any Senior Indebtedness under any
revolving credit facility, effect a permanent reduction in the availability
under such revolving credit facility, (B) to reinvest in Productive Assets, or
(C) a combination of prepayment and investment permitted by the foregoing
clauses (iii)(A) and (iii)(B). On the 366th day after an Asset Sale or such
earlier date, if any, as the Board of Directors of the Company or of such
Restricted Subsidiary determines not to apply the Net Cash Proceeds relating
to such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of
the immediately preceding sentence (each, a "Net Proceeds Offer Trigger
Date"), such aggregate amount of Net Cash Proceeds which have not been applied
on or before such Net Proceeds Offer Trigger Date as permitted in clauses
(iii)(A), (iii)(B) and (iii)(C) of the immediately preceding sentence (each a
"Net Proceeds Offer Amount") shall be applied by the Company or such
Restricted Subsidiary to make an offer to purchase (the "Net Proceeds Offer")
on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more
than 45 days following the applicable Net Proceeds Offer Trigger Date, from
all Holders on a pro rata basis that amount of Notes equal to the Net Proceeds
Offer Amount at a price equal to 100% of the principal amount of the Notes to
be purchased, plus accrued and unpaid interest thereon, if any, to the date of
purchase; provided, however, that if at any time any non-cash consideration
received by the Company or any Restricted Subsidiary of the Company, as the
case may be, in connection with any Asset Sale is converted into or sold or
otherwise disposed of for cash (other than interest received with respect to
any such non-cash consideration), then such conversion or disposition shall be
deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof
shall be applied in accordance with this covenant.
 
  Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less than
$10 million, the application of the Net Cash Proceeds constituting such Net
Proceeds Offer Amount to a Net Proceeds Offer may be deferred until such time
as such Net Proceeds Offer Amount plus the aggregate amount of all Net
Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger
Date relating to such initial Net Proceeds Offer Amount from all Asset Sales
by the Company and its Restricted Subsidiaries aggregates at least $10
million, at which time the Company or such Restricted Subsidiary shall apply
all Net Cash Proceeds constituting all Net Proceeds Offer Amounts that have
been so deferred to make a Net Proceeds Offer (the first date the aggregate of
all such deferred Net Proceeds Offer Amounts is equal to $10 million or more
shall be deemed to be a "Net Proceeds Offer Trigger Date").
 
  Notwithstanding the two immediately preceding paragraphs, the Company and
its Restricted Subsidiaries will be permitted to consummate an Asset Sale
without complying with such paragraphs to the extent (i) at least 75% of the
consideration for such Asset Sale constitutes Productive Assets and (ii) such
Asset Sale is for at least fair market value (as determined in good faith by
the Company's Board of Directors); provided that any consideration not
constituting Productive Assets received by the Company or any of its
Restricted Subsidiaries in connection with any Asset Sale permitted to be
consummated under this paragraph shall constitute Net Cash Proceeds and shall
be subject to the provisions of the two preceding paragraphs.
 
  Each Net Proceeds Offer will be mailed to the record Holders as shown on the
register of Holders within 25 days following the Net Proceeds Offer Trigger
Date, with a copy to the Trustee, and shall comply with the procedures set
forth in the Indenture. Upon receiving notice of the Net Proceeds Offer,
 
                                      76
<PAGE>
 
Holders may elect to tender their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders properly
tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of
tendering Holders will be purchased on a pro rata basis (based on amounts
tendered). A Net Proceeds Offer shall remain open for a period of 20 business
days or such longer period as may be required by law. To the extent that the
aggregate amount of Notes tendered pursuant to a Net Proceeds Offer is less
than the Net Proceeds Offer Amount, the Company may use any remaining Net
Proceeds Offer Amount for general corporate purposes. Upon completion of any
such Net Proceeds Offer, the Net Proceeds Offer Amount shall be reset at zero.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset
Sale" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Asset Sale" provisions of the Indenture by
virtue thereof.
 
  Future Guarantees. The Company will not permit any of its Restricted
Subsidiaries, directly or indirectly, to incur, guarantee or secure through
the granting of Liens the payment of the Bank Indebtedness or any refunding or
refinancing thereof, in each case unless such Restricted Subsidiary, the
Company and the Trustee execute and deliver a supplemental indenture
evidencing such Restricted Subsidiary's Guarantee, such Guarantee to be a
senior subordinated unsecured obligation of such Restricted Subsidiary.
Neither the Company nor any such Subsidiary Guarantor shall be required to
make a notation on the Notes or the Guarantees to reflect any such subsequent
Guarantee. Nothing in this covenant shall be construed to permit any
Restricted Subsidiary of the Company to incur Indebtedness otherwise
prohibited by the "Limitation on Incurrence of Additional Indebtedness"
covenant. Thereafter, such Restricted Subsidiary shall be a Subsidiary
Guarantor for all purposes of the Indenture.
 
  Conduct of Business. The Company and its Restricted Subsidiaries will not
engage in any businesses which are not the same, similar, related or ancillary
to the businesses in which the Company and its Restricted Subsidiaries are
engaged on the Issue Date.
 
EVENTS OF DEFAULT
 
  The following events are defined in the Indenture as "Events of Default":
(i) the failure to pay interest on any Notes when the same becomes due and
payable and the default continues for a period of 30 days (whether or not such
payment shall be prohibited by the subordination provisions of the Indenture);
(ii) the failure to pay the principal on any Notes, when such principal
becomes due and payable, at maturity, upon redemption or otherwise (including
the failure to make a payment to purchase Notes tendered pursuant to a Change
of Control Offer or a Net Proceeds Offer) (whether or not such payment shall
be prohibited by the subordination provisions of the Indenture); (iii) a
default in the observance or performance of any other covenant or agreement
contained in the Indenture which default continues for a period of 30 days
after the Company receives written notice specifying the default (and
demanding that such default be remedied) from the Trustee or the Holders of at
least 25% of the outstanding principal amount of the Notes; (iv) the failure
to pay at final maturity (giving effect to any applicable grace periods and
any extensions thereof) the principal amount of any Indebtedness of the
Company or any Restricted Subsidiary (other than a Receivables Entity) of the
Company, or the acceleration of the final stated maturity of any such
Indebtedness if the aggregate principal amount of such Indebtedness, together
with the principal amount of any other such Indebtedness in default for
failure to pay principal at final maturity or which has been accelerated,
aggregates $10 million or more at any time; (v) one or more judgments in an
aggregate amount in excess of $10 million shall have been rendered against the
Company or any of its Restricted Subsidiaries and such judgments remain
 
                                      77
<PAGE>
 
undischarged, unpaid or unstayed for a period of 60 days after such judgment
or judgments become final and non-appealable; (vi) certain events of
bankruptcy affecting the Company or any of its Significant Subsidiaries; and
(vii) any of the Guarantees of the Subsidiary Guarantors that are also
Significant Subsidiaries of the Company ceases to be in full force and effect
or any of such Guarantees is declared to be null and void and unenforceable or
any of such Guarantees is found to be invalid or any of such Subsidiary
Guarantors denies its liability under its Guarantee (other than by reason of
release of such Subsidiary Guarantor in accordance with the terms of the
Indenture).
 
  Upon the happening of any Event of Default specified in the Indenture, the
Trustee or the Holders of at least 25% in principal amount of outstanding
Notes may declare the principal of and accrued interest on all the Notes to be
due and payable by notice in writing to the Company and the Trustee specifying
the respective Event of Default and that it is a "notice of acceleration", and
the same shall become immediately due and payable. If an Event of Default with
respect to bankruptcy proceedings of the Company occurs and is continuing,
then such amount shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any holder
of Notes.
 
  The Indenture will provide that, at any time after a declaration of
acceleration with respect to the Notes as described in the preceding
paragraph, the Holders of a majority in principal amount of the Notes may
rescind and cancel such declaration and its consequences (i) if the rescission
would not conflict with any judgment or decree, (ii) if all existing Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration, (iii) to the extent
the payment of such interest is lawful, interest on overdue installments of
interest and overdue principal, which has become due otherwise than by such
declaration of acceleration, has been paid, (iv) if the Company has paid the
Trustee its reasonable compensation and reimbursed the Trustee for its
expenses, disbursements and advances and (v) in the event of the cure or
waiver of an Event of Default of the type described in clause (vi) or (vii) of
the description above of Events of Default, the Trustee shall have received an
officers' certificate and an opinion of counsel that such Event of Default has
been cured or waived. The holders of a majority in principal amount of the
Notes may waive any existing Default or Event of Default under the Indenture,
and its consequences, except a default in the payment of the principal of or
interest on any Notes.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Subsidiary Guarantors discharged with
respect to the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes, except for (i) the rights
of holders of the Notes to receive payments in respect of the principal of,
premium, if any, and interest on the Notes when such payments are due, (ii)
the Company's obligations with respect to the Notes concerning issuing
temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen
Notes and the maintenance of an office or agency for payments, (iii) the
rights, powers, trust, duties and immunities of the Trustee and the Company's
obligations in connection therewith and (iv) the Legal Defeasance provisions
of the Indenture. In addition, the Company may, at its option and at any time,
elect to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, reorganization and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the
Notes.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the holders of the Notes cash in U.S. dollars, non-callable U.S. government
obligations, or a combination thereof, in such amounts as will
 
                                      78
<PAGE>
 
be sufficient, in the opinion of a nationally recognized firm of independent
public accountants, to pay the principal of, premium, if any, and interest on
the Notes on the stated date for payment thereof or on the applicable
redemption date, as the case may be; (ii) in the case of Legal Defeasance, the
Company shall have delivered to the Trustee an opinion of counsel in the
United States reasonably acceptable to the Trustee confirming that (A) the
Company has received from, or there has been published by, the Internal
Revenue Service a ruling or (B) since the date of the Indenture, there has
been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such opinion of counsel shall confirm that, the
holders of the Notes will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal Defeasance and will be subject
to federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Legal Defeasance had not occurred;
(iii) in the case of Covenant Defeasance, the Company shall have delivered to
the Trustee an opinion of counsel in the United States reasonably acceptable
to the Trustee confirming that the holders of the Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case
if such Covenant Defeasance had not occurred; (iv) no Default or Event of
Default shall have occurred and be continuing on the date of such deposit
(other than a Default or Event of Default with respect to the Indenture
resulting from the incurrence of Indebtedness, all or a portion of which will
be used to defease the Notes concurrently with such incurrence); (v) such
Legal Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default under the Indenture or any other
material agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Company shall have delivered to the Trustee an officers'
certificate stating that the deposit was not made by the Company with the
intent of preferring the holders of the Notes over any other creditors of the
Company or with the intent of defeating, hindering, delaying or defrauding any
other creditors of the Company or others; (vii) the Company shall have
delivered to the Trustee an officers' certificate and an opinion of counsel,
each stating that all conditions precedent provided for or relating to the
Legal Defeasance or the Covenant Defeasance have been complied with; (viii)
the Company shall have delivered to the Trustee an opinion of counsel to the
effect that (A) the trust funds will not be subject to any rights of holders
of Indebtedness of the Company other than the Notes and (B) assuming no
intervening bankruptcy of the Company between the date of deposit and the 91st
day following the deposit and that no Holder of the Notes is an insider of the
Company, after the 91st day following the deposit, the trust funds will not be
subject to the effect of any applicable bankruptcy, insolvency, reorganization
or similar laws affecting creditors' rights generally; and (ix) certain other
customary conditions precedent are satisfied.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Trustee for
cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation have become due and payable and the Company has irrevocably
deposited or caused to be deposited with the Trustee funds in an amount
sufficient to pay and discharge the entire Indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, for principal of,
premium, if any, and interest on the Notes to the date of deposit together
with irrevocable instructions from the Company directing the Trustee to apply
such funds to the payment thereof at maturity or redemption, as the case may
be; (ii) the Company has paid all other sums payable under the Indenture by
the Company; and (iii) the Company has delivered to the Trustee an officers'
certificate and an opinion of counsel stating that all conditions precedent
under the Indenture relating to the satisfaction and discharge of the
Indenture have been complied with.

MODIFICATION OF THE INDENTURE
 
  From time to time, the Company, the Subsidiary Guarantors and the Trustee,
without the consent of the Holders of the Notes, may amend the Indenture for
certain specified purposes, including curing ambiguities, defects or
inconsistencies, so long as such change does not, in the opinion of the
Trustee, adversely affect the rights of any of the Holders in any material
respect. In formulating its opinion on such matters, the Trustee will be
entitled to rely on such evidence as it deems appropriate, including, without
limitation, solely on an opinion of counsel. Other modifications and
amendments of the Indenture may be made with the consent of the Holders of a
majority in principal amount of the then outstanding Notes issued under the
Indenture, except that, without the consent of each holder of the Notes
affected thereby, no amendment may: (i) reduce the amount of Notes whose
holders must consent to an amendment; (ii) reduce the rate of or change or
have the effect of changing the time for payment of interest, including
defaulted interest, on any Notes; (iii) reduce the principal of or change or
have the effect of changing the fixed maturity of any Notes, or change the
date on which any Notes may be subject to redemption or repurchase, or reduce
the redemption or repurchase price therefor; (iv) make any Notes payable in
money other than that stated in the Notes; (v) make any change in provisions
of the Indenture protecting the right of each holder of a Note to receive
payment of principal of and interest on such Note on or after the due date
thereof or to bring suit to enforce such payment, or permitting holders of a
majority in principal amount of the Notes to waive Defaults or Events of
Default (other than Defaults or Events of Default with respect to the payment
of principal of or interest on the Notes); (vi) amend, change or modify in any
material respect the obligation of the Company to make and consummate a Change
of Control Offer in the event of a Change of Control Triggering Event or make

been consummated or modify any of the provisions or definitions with respect
thereto; (vii) modify the subordination provisions (including the related
definitions) of the Indenture to adversely affect the holders of Notes in any
material respect; or (viii) release any Subsidiary Guarantor that is a
Significant Subsidiary of the Company from any of its obligations under its
Guarantee or the Indenture otherwise than in accordance with the terms of the
Indenture.

  "Consolidated Fixed Charge Coverage Ratio" means, with respect to any
Person, the ratio of Consolidated EBITDA of such Person during the four full
fiscal quarters (the "Four Quarter Period") ending on or prior to the date of

Charge Coverage Ratio (the "Transaction Date") to Consolidated Fixed Charges
of such Person for the Four Quarter Period. In addition to and without
limitation of the foregoing, for purposes of this definition, "Consolidated
EBITDA" and "Consolidated Fixed Charges" shall be calculated after giving
effect on a pro forma basis for the period of such calculation to (i) the
incurrence of any Indebtedness of such Person or any of its Restricted
Subsidiaries (and the application of the proceeds thereof) giving rise to the
need to make such calculation and any incurrence or repayment of other
Indebtedness (and the application of the proceeds thereof) occurring during
the Four Quarter Period or at any time subsequent to the last day of the Four
Quarter Period and on or prior to the Transaction Date, as if such incurrence
or repayment, as the case may be (and the application of the proceeds
thereof), occurred on the first day of the Four Quarter Period, (ii) any Asset
Sales or Asset Acquisitions (including, without limitation, any Asset
Acquisition giving rise to the need to make such calculation as a result of
such Person or one of its Restricted Subsidiaries (including any Person who
becomes a Restricted Subsidiary as a result of the Asset Acquisition)
incurring, assuming or otherwise being liable for Acquired Indebtedness and
also including any Consolidated EBITDA (including any pro forma expense and
cost reductions that are (i) directly attributable to such transaction and
(ii) factually supportable) attributable to the assets which are the subject
of the Asset Acquisition or Asset Sale during the Four Quarter Period)
occurring during the Four Quarter Period or at any time subsequent to the last
day of the Four Quarter Period and on or prior to the Transaction Date, as if
such Asset Sale or Asset Acquisition (including the incurrence, assumption or
liability for any such Indebtedness or Acquired Indebtedness) occurred on the
first day of the Four Quarter Period, (iii) with respect to any such Four
Quarter Period commencing prior to the Recapitalization, the Recapitalization
(including any pro forma expense and cost reductions related thereto that are
(i) directly attributable to such transaction and (ii) factually supportable)
shall be deemed to have taken place on the first day of such Four Quarter
Period and (iv) any asset sales or asset acquisitions (including any
Consolidated EBITDA (including any pro forma expense and cost reductions that
are (i) directly attributable to such transaction and (ii) factually
supportable) attributable to the assets which are the subject of the asset
acquisition or asset sale during the Four Quarter Period) that have been made
by any Person that has become a Restricted Subsidiary of the Company or has
been merged with or into the Company or any Restricted Subsidiary of the
Company during the Four Quarter Period or at any time subsequent to the last
day of the Four Quarter Period and on or prior to the Transaction Date that
would have constituted Asset Sales or Asset Acquisitions had such transactions
occurred when such Person was a Restricted Subsidiary of the Company or
subsequent to such Person's merger into the Company, as if such asset sale or
asset acquisition (including the incurrence, assumption or liability for any
Indebtedness or Acquired Indebtedness in connection therewith) occurred on the
first day of the Four Quarter Period; provided that to the extent that clause
(ii) or (iv) of this sentence requires that pro forma effect be given to an
asset sale or asset acquisition, such pro forma calculation shall be based
 
                                      83
<PAGE>
 
upon the four full fiscal quarters immediately preceding the Transaction Date
of the Person, or division or line of business of the Person, that is acquired
or disposed for which financial information is available. If such Person or
any of its Restricted Subsidiaries directly or indirectly guarantees
Indebtedness of a third Person, the preceding sentence shall give effect to
the incurrence of such guaranteed Indebtedness as if such Person or any
Restricted Subsidiary of such Person had directly incurred or otherwise
assumed such guaranteed Indebtedness. Furthermore, in calculating
"Consolidated Fixed Charges" for purposes of determining the denominator (but
not the numerator) of this "Consolidated Fixed Charge Coverage Ratio," (1)
interest on outstanding Indebtedness determined on a fluctuating basis as of
the Transaction Date and which will continue to be so determined thereafter
shall be deemed to have accrued at a fixed rate per annum equal to the rate of
interest on such Indebtedness in effect on the Transaction Date; (2) if
interest on any Indebtedness actually incurred on the Transaction Date may
optionally be determined at an interest rate based upon a factor of a prime or
similar rate, a eurocurrency interbank offered rate, or other rates, then the
interest rate in effect on the Transaction Date will be deemed to have been in
effect during the Four Quarter Period; and (3) notwithstanding clause (1)
above, interest on Indebtedness determined on a fluctuating basis, to the
extent such interest is covered by agreements relating to Interest Swap
Obligations, shall be deemed to accrue at the rate per annum resulting after
giving effect to the operation of such agreements.
 
  "Consolidated Fixed Charges" means, with respect to any Person for any
period, the sum, without duplication, of (i) Consolidated Interest Expense
(before amortization or write-off of debt issuance costs in connection with
the Transactions) plus (ii) the product of (x) the amount of all dividend
payments on any series of Preferred Stock of such Person (other than dividends
paid in Qualified Capital Stock) times (y) a fraction, the numerator of which
is one and the denominator of which is one minus the then current effective
consolidated Federal, state and local tax rate of such Person expressed as a

                       DESCRIPTION OF CREDIT FACILITIES
   
  Chemical Bank and Bankers Trust Company have committed to provide, or
arrange for a syndicate of lenders to provide, to the Company, subject to
certain terms and conditions, the Credit Facilities in an aggregate principal
amount not to exceed $625.0 million. At the closing of the Transactions, (i)
approximately $550.0 million is expected to be drawn under the Term Loan
Facility (as defined below) and (ii) $10.0 million is expected to be borrowed
under the Revolving Facility (as defined below) under which $75.0 million is
available on a revolving credit basis for general corporate purposes of the
Company and its subsidiaries.     
   
  Structure. The Credit Facilities will consist of (a) a term loan facility in
an aggregate principal amount of $550.0 million (the "Term Loan Facility"),
consisting of three tranches in principal amounts of $200.0 million, $175.0
million and $175.0 million (the "Tranche A Term Loan," "Tranche B Term Loan"
and "Tranche C Term Loan," respectively) and (b) a revolving credit facility
providing for revolving loans to the Company and the issuance of letters of
credit for the account of the Company in an aggregate principal amount
(including the aggregate stated amount of letters of credit and the aggregate
reimbursement and other obligations in respect thereof) at any time not to
exceed $75.0 million (the "Revolving Facility").     
 
  Availability. The availability of the Credit Facilities will be subject to
various conditions precedent typical for bank loans, and Chemical Bank's and
Bankers Trust Company's commitments to provide the Credit Facilities are also
subject to, among other things, the completion of Chemical Bank's and Bankers
Trust Company's financial and legal review of the Company and the
Transactions, and the absence of any material adverse change with respect to
the Company in particular or the financial, banking or capital markets in
general. The full amount of the Term Loan Facility must be drawn in a single
drawing at the closing of the Transactions and amounts repaid or prepaid under
the Term Loan Facility may not be reborrowed.
 
  The Tranche A Term Loan and the Revolving Facility will mature on the sixth
anniversary of the Closing Date. The Tranche B Term Loan will mature on the
seventh anniversary of the Closing Date and the Tranche C Term Loan will
mature on the eighth anniversary of the Closing Date. Amortization of the Term
Loan Facility will be in quarterly payments, in amounts to be agreed upon,
commencing 18 months from Closing. The Tranche A Term Loan will amortize
quarterly over six years, the Tranche B Term Loan will amortize quarterly over
seven years and the Tranche C Term Loan will amortize quarterly over eight
years. (The Tranche B and C Term Loans will amortize in nominal amounts during
the first 6 and 7 years, respectively). In addition, the Credit Facilities are
subject to mandatory prepayment and reductions (to be applied first to the
Term Loan Facility) in an amount equal to, subject to certain exceptions, (a)
100% of the net proceeds of (i) certain debt offerings by Holdings or any of
its subsidiaries and (ii) certain asset sales or other dispositions and (b) a
percentage of up to 75% of the Company's excess operating cash flow, such
percentage to be determined in accordance with the terms of the definitive
documentation.
 
  Security; Guaranty. The obligations of the Company under the Credit
Facilities will be unconditionally and irrevocably guaranteed by Holdings and
its domestic subsidiaries. In addition, the Credit Facilities and the
guarantees thereunder will be secured by security interests in and pledges of
or liens on substantially all the material tangible and intangible assets of
the Company and the guarantors, including pledges of all the capital stock of,
or other equity interests in, the Company and each direct or indirect domestic
subsidiary of the Company and 65%, subject to increase, of the capital stock
of, or other equity interests in, each foreign subsidiary of the Company.
 
  Interest. At the Company's election, the interest rates per annum applicable
to the loans under the Credit Facilities will be a fluctuating rate of
interest measured by reference to either (a) an adjusted
 
                                      95
<PAGE>
 
London inter-bank offered rate ("LIBOR") plus a borrowing margin or (b) an
alternate base rate ("ABR") (equal to the higher of Chemical Bank's published
prime rate and the Federal Funds effective rate plus 1/2 of 1%) plus a
borrowing margin. The borrowing margins applicable to Tranche A Term Loan and
loans under the Revolving Facility will be 1.50% for ABR loans and 2.50% for
LIBOR loans. These margins will be subject to reduction after the first
anniversary of the Closing Date if certain financial performance thresholds
are met. The interest rate borrowing margins applicable to the Tranche B Term
Loan and the Tranche C Term Loan will be 2.00% and 2.50%, respectively, for
ABR loans and 3.00% and 3.50%, respectively, for LIBOR loans and will not be
subject to reduction. Amounts under the Credit Facilities not paid when due
bear interest at a default rate equal to 2.00% above the rate otherwise
applicable.
 
  Fees. The Company has agreed to pay certain fees with respect to the Credit
Facilities, including (i) fees on the unused commitments of the lenders equal
to 1/2 of 1% of the undrawn portion of the commitments in respect of the
facilities; (ii) letter of credit fees on the aggregate face amount of
outstanding letters of credit equal to the then applicable borrowing margin
for LIBOR Revolving Loans plus a per annum fronting bank fee for the letter of
credit issuing bank; (iii) annual administration fees; and (iv) agent,
arrangement and other similar fees.
 
  Covenants. The Credit Facilities will contain a number of covenants that,
among other things, will restrict the ability of Holdings, the Company and its
subsidiaries to dispose of assets, incur additional indebtedness, incur
guarantee obligations, prepay other indebtedness or amend other debt
instruments, pay dividends, create liens on assets, make investments, loans or
advances, make acquisitions, create subsidiaries, engage in mergers or
consolidations, change the business conducted by the Company, make capital
expenditures, or engage in certain transactions with affiliates and otherwise
restrict certain corporate activities. In addition, under the Credit
Facilities, the Company will be required to comply with specified financial
ratios and minimum tests, including minimum interest coverage ratios, maximum
leverage ratios and minimum EBITDA covenants.
 
  The Credit Facilities will also contain provisions that will limit the
Company's ability to make any amendment or modification of the Indenture and
the Company's ability to prepay or refinance the Notes without the consent of
such lenders.
 
  Events of Default. The Credit Facilities will contain customary events of
default including non-payment of principal, interest or fees, violation of
covenants, inaccuracy of representations or warranties in any material
respect, cross default and cross acceleration to certain other indebtedness,
bankruptcy, material judgments and liabilities and change of control.

To the Board of Directors
and Stockholders of Experian Information Solutions, Inc.
 
  In our opinion, the accompanying balance sheet presents fairly, in all
material respects, the financial position of Experian Information Solutions,
Inc. (formerly known as IntelliData, Inc.) at June 12, 1996 (Inception) in
conformity with generally accepted accounting principles. The balance sheet is
the responsibility of the Company's management; our responsibility is to
express an opinion on the balance sheet based on our audit. We conducted our
audit of the balance sheet in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the balance sheet is free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the balance sheet, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall balance sheet presentation. We believe that our audit
provides a reasonable basis for the opinion expressed above.

                        REPORT OF INDEPENDENT AUDITORS
 
TRW Inc.
 
  We have audited the accompanying combined balance sheets of TRW Information
Systems & Services as of December 31, 1994 and 1995, and the related combined
statements of earnings and cash flows for each of the three years in the
period ended December 31, 1995. These financial statements are the
responsibility of TRW Inc.'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 combined financial position of TRW Information
Systems & Services at December 31, 1994 and 1995, and the combined results of
its operations and its cash flows for each of the three years in the period
ended December 31, 1995, in conformity with generally accepted accounting
principles.
 
  As discussed in Note B to the combined financial statements, effective
January 1, 1993, TRW Information Systems & Services changed its method of
accounting for post-employment benefits.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
                       DECEMBER 31, 1993, 1994 AND 1995
                            (THOUSANDS OF DOLLARS)
 
A. BASIS OF PRESENTATION
 
  These combined financial statements of TRW Information Systems & Services
(TRW IS&S) include: TRW Information Services, TRW Business Credit Services and
IS&S Staff, which are divisions of TRW Inc. (TRW); IS&S International, Inc.,
Hotel Management Inc. and Information Systems and Services, Inc., which are
wholly-owned subsidiaries of TRW; and TRW REDI Property Data (TRW REDI), in
which TRW owns a 60% partnership interest. All significant intragroup accounts
and transactions have been eliminated in combination. The combined financial
statements exclude certain operating units historically included in TRW's
Information Systems & Services business segment.
 
  TRW IS&S operates in a single line of business, substantially all of which
is domestic--the sale of consumer and business information--organized along
three product lines: Consumer Information Services, Business Information
Services, and Real Estate Information Services. Consumer Information Services
provides consumer credit reports to retailers, financial organizations, and
other credit-granting organizations. Business Information Services provides
business credit decision support and demographic information for business-to-
business credit granting and direct marketing efforts to retailers and other
credit-granting organizations. Real Estate Information Services provides
property data services and title information services to title companies,
appraisers, and real estate brokers.
 
B. SIGNIFICANT ACCOUNTING POLICIES
 
 Revenue Recognition
 
  Revenue is recognized as credit reports are issued or customer inquiries of
TRW IS&S' databases are made. Billings to customers prior to the completion of
the earnings process are deferred on the balance sheet.
 
 Cash Equivalents
 
  For purposes of the statement of cash flows, TRW IS&S considers all highly
liquid investments purchased with a maturity of three months or less to be
cash equivalents.
 
 Accounts Receivable
 
  Credit risk with respect to accounts receivable is concentrated principally
with financial institutions, retail organizations, and property data and title
information users. Customers are not required to provide collateral. TRW IS&S
has established receivable reserves of $4,699 and $4,704 at December 31, 1994
and 1995, respectively.

  Investment
 
  TRW IS&S has invested in Comcred S.A. de CV ("Comcred"), a start-up Mexican
credit data company. TRW IS&S purchased 2,400 shares of Comcred's Series B
stock (20% interest) for $750. TRW IS&S has entered into three note agreements
which allow Comcred to draw down cash as necessary. As of December 31, 1995,
TRW IS&S has principal and interest totaling $4,518 outstanding under the
notes. Two of the promissory notes have conversion features which allow TRW
IS&S to convert an amount of principal and interest that would result in
issuance of an additional 29% of Comcred's total voting securities. TRW IS&S
accounts for its investment in Comcred using the equity method of accounting.
During 1995, TRW IS&S recorded $1,000 of losses to reflect its estimated share
of the inception to date loss of Comcred.

  For the years ended December 31, 1993, 1994 and 1995 amortization expense
was $69,098, $65,767 and $63,702, including $3,320, $2,383 and $1,853 for
capitalized software, respectively.
 
  Capitalized Data Files--Costs associated with modifying data files with
current data to create updated and new files are capitalized. Purchased data
files, with a net book value of $124,267 and $110,831 at December 31, 1994 and
1995, respectively, are amortized by the straight-line method over 15 years,
and other capitalized data file information is amortized over three to five
years.
 
  Intangibles Arising from Acquisitions--Intangibles arising from acquisitions
prior to 1971 of $24,907 are not being amortized because there is no
indication of diminished value. Intangibles arising from acquisitions after
1970 are being amortized by the straight-line method over 40 years.
 
  Other Intangible Assets--Costs incurred for new software products are
charged to research and development expense until technological feasibility is
established. Thereafter, certain costs are capitalized. Amortization begins
when the product is used in a revenue producing capacity. During 1992, TRW
IS&S began development of a new system to provide on-line decision-support
services. For the years ended December 31, 1993, 1994 and 1995, charges to
research and development expense related to this project were $5,196, $10,682
and $24,322, respectively. During 1994, the project attained technological
feasibility and $10,960 and $9,654 were capitalized in 1994 and 1995,

respectively. Initial operation of the system is planned for the second
quarter of 1996. Capitalized software is amortized by the straight-line method
over three to five years.
 
  Other intangible assets are being amortized on a straight-line basis over
their estimated useful lives, typically no more than seven years. Based upon
its most recent analysis, management believes that no material impairment of
intangible assets exists at December 31, 1995. Title plants are not amortized.
 
 Accounting Change
 
  Effective January 1, 1993, TRW IS&S adopted Statement of Financial
Accounting Standards No. 112, Employers' Accounting for Postemployment
Benefits, which requires accrual of the cost of benefits provided to former or
inactive employees after employment but before retirement. TRW IS&S' previous
practice was to record the cost of certain of these benefits as incurred.
 
 Income Taxes
 
  TRW IS&S, except for TRW REDI, is included in the TRW consolidated tax
return. Income taxes have been provided on a separate return basis. Deferred
income taxes reflect the net tax effects of temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes
and the amounts used for income tax purposes.
 
 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 and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
 Other Matters
 
  In 1993, other (income) expense includes expense of $10,512 before tax
($6,938 after tax) to write off an intercompany note receivable from TRW RELS.
 
  In 1993, a reserve of $1,100 before tax ($720 after tax) for employee
related benefits for former employees was reversed.
 
  In 1994, other (income) expense includes a gain of $17,728 before tax
($11,523 after tax) on the sale of Credentials, a direct-to-consumer credit
monitoring business.
 
  In 1995, other (income) expense includes gains of $1,257 before tax ($817
after tax) on the sale of two product lines.
 
 Pending Accounting Standards
 
  The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of. Statement No. 121
establishes accounting standards for determining the impairment of long-lived
assets to be held and used, certain identifiable intangibles, and goodwill
related to those assets and for long-lived assets and certain identifiable
intangibles to be disposed of. TRW IS&S is required to adopt Statement No. 121
during the first quarter of 1996 and it will not have a material effect on the
financial condition or results of operations.

D. EMPLOYEE BENEFIT PLANS
 
 Pension Plans
 
  Substantially all TRW IS&S employees, except for employees of TRW REDI, are
covered by TRW defined benefit pension plans (noncontributory). Plans for most
salaried employees provide pay-related benefits based on years of service.
Under TRW's funding policy, annual contributions are made to fund the plans
during the participants' working lifetimes, except for nonqualified plans
which are funded as benefits are paid to participants. Annual contributions to
funded plans have met or exceeded ERISA's minimum funding requirements.
 
  Employees of TRW IS&S, except for employees of TRW REDI, may participate in
a TRW sponsored contributory stock savings plan. TRW matches employee
contributions up to 3% of the participant's qualified compensation. TRW
contributions are held in an unleveraged employee stock ownership plan.
 
  TRW REDI sponsors a defined contribution pension plan covering substantially
all of its employees. TRW REDI matches employee contributions up to 3% of the
participant's qualified compensation.
 
  TRW allocates pension cost to TRW IS&S on the basis of payroll for funded
plans and projected liabilities for unfunded plans. The following is a summary
of the components of net periodic pension cost for defined benefit plans and
the total cost for the stock savings plan and the defined contribution plan.

  As of December 31, 1994 and 1995, the discount rate used in determining the
actuarial present value of benefit obligations was 8 1/2% and 7%,
respectively, and the projected rate of increase in future compensation levels
was 3% for 1994 and 4% for 1995. The expected long-term rate of return on
assets was 9% for 1994 and 1995.
 
 Postretirement Benefits Other than Pensions
 
  A majority of TRW IS&S' retired employees are provided health care and life
insurance benefits by TRW. TRW REDI provides no postretirement benefits other
than pensions. The health care plans provide for cost sharing, in the form of
employee contributions, deductibles, and coinsurance, between TRW IS&S and its
retirees. The postretirement health care plan covering a majority of employees
who retired since August 1, 1988 limits the annual increase in TRW IS&S'
contribution toward the plan's cost to a maximum of the lesser of 50% of
medical inflation or 4%. Life insurance benefits are generally
noncontributory. TRW IS&S' policy is to fund the cost of postretirement health
care and life insurance benefits in amounts determined at the discretion of
TRW management. The Plans are currently not prefunded.
 
  The following table sets forth the funded status and amounts recognized in
TRW IS&S' balance sheets at December 31, 1994 and 1995 for its postretirement
benefit plans.

</TABLE>
 
  The discount rate used in determining the accumulated postretirement benefit
obligation as of December 31, 1994 and 1995 was 8 1/2% and 7%, respectively.
At December 31, 1994, the 1995 annual rate of increase in the per capita cost
of covered health care benefits was assumed to be 10% for participants under
age 65 and 9% for participants age 65 or older. The rates were assumed to
decrease gradually to 6% and 5%, respectively, in the year 2021 and remain at
that level thereafter. At December 31, 1995, the 1996 annual rate of increase
in the per capita cost of covered health care benefits was assumed to be 10%
for participants under age 65 and 9% for participants age 65 or older. The
rates were assumed to decrease gradually to 6% and 5%, respectively, in the
year 2021 and remain at that level thereafter. A one percent annual increase
in these assumed cost trend rates would increase the accumulated
postretirement benefit obligation at December 31, 1995 by approximately 8%,
and the aggregate of the service and interest cost components of net periodic
postretirement benefit cost for 1995 by approximately 9%.
 
  The change in discount rate and the assumed annual rates of increase in the
per capita cost of covered health care benefits at December 31, 1994, reflect
higher prevailing interest rates and lower expected medical inflation. The
change in discount rate at December 31, 1995, reflects lower prevailing
interest rates.
 
E. INCOME TAXES
 
  Income taxes differ from the statutory rate principally due to the

</TABLE>
 
  Amounts paid to TRW for income taxes in 1993, 1994 and 1995 were $9.1
million, $32.6 million and $22.0 million, respectively.
 
F. LEASE COMMITMENTS
 
  TRW IS&S leases certain buildings, offices, computer and office equipment,
and automobiles under operating leases. Such leases, some of which are
noncancelable and in some cases include renewals, expire at various dates. TRW
IS&S pays most maintenance, insurance, and tax expense relating to leased
assets. Rental expense for operating leases was $42,000 in 1993 and 1994 and
$51,000 in 1995.
 
  At December 31, 1995, future minimum lease payments for noncancelable
operating leases totaled $131,000 and are payable as follows: 1996 - $30,000;
1997 - $21,000; 1998 - $12,000; 1999 -  $10,000; 2000 - $9,000; and $49,000
thereafter.
 
G. ACQUISITIONS
 
  In 1995, TRW IS&S purchased substantially all of the assets of Professional
Real Estate Tax Service, Inc. (PRE) and American Business Corporation (ABC).
TRW IS&S issued $1,250 of 8% promissory notes that require payment in 20 equal
quarterly installments of principal plus interest on the unpaid principal
balance starting October 1, 1995 and ending July 1, 2000. At December 31,
1995, $1,211 is outstanding under the notes. In addition to the promissory
notes, TRW IS&S agreed to pay additional consideration as follows: for a
period of 120 calendar months, commencing July 1995 and ending July 2005, TRW
IS&S shall pay to the seller of PRE and ABC amounts equal to 3% and 7%,
respectively, of the monthly gross billable revenues for tax services rendered
during such months by PRE and ABC.
 
  In 1994, TRW IS&S acquired all of the outstanding stock of Rufus S. Lusk &
Son, Inc. (Lusk) for $5,750 in a purchase business combination. The estimated
excess purchase price of $5,533 has been determined based on the allocation of
the purchase price to the assets acquired and liabilities assumed and is being
amortized on the straight-line basis over 40 years. The operating results of
Lusk are included in the combined statement of earnings from the date of
acquisition.
 
  A note payable was issued to the shareholders of Lusk in connection with the
acquisition. The note balance is $925 at December 31, 1995 and bears interest
at a variable rate (8.75% at December 31, 1995) and is payable in monthly
installments of $42 through October 1997.

H. DIVESTITURE
 
  In 1995, TRW IS&S sold the California C&I Business and the C&I Data Extract
Business (in certain territories) to COMPS Infosystems, Inc. (COMPS). TRW IS&S
retained all liabilities related to the divested businesses. As consideration,
TRW IS&S received $225 in cash and promissory notes with a face value of $750.
At December 31, 1995, TRW IS&S has a note receivable from COMPS of $425. TRW
IS&S recorded a before tax gain on sale of $543.
 
  In 1995, TRW IS&S sold the Search Access product line for $800 in cash and
recorded a before tax gain of $714.
 
I. RESTRUCTURING
 
  Prior to 1994, TRW IS&S recognized restructuring and related costs when
management and the Board of Directors of TRW approved a formal plan of action
to restructure and amounts were reasonably estimable and probable to be paid.
At that time, incremental costs directly associated with the restructuring
plan were accrued by a charge to operations. Beginning in 1994, restructuring
and related costs were recognized in accordance with Emerging Issues Task
Force Issue No. 94-3, Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred
in a Restructuring).
 
  At December 31, 1994 and 1995, other accruals include $10,666 and $2,673,
respectively, relating to restructuring reserves:

</TABLE>
 
  In 1994, restructuring expense of $8,800 was recorded to cover the costs of
closing, downsizing, and relocating certain facilities and restructuring of
the TRW REDI organization. Key elements of the restructuring program, which is
expected to be completed in 1997, included termination benefits for
approximately 370 employees from throughout the organization, including data
entry personnel, supervisors, and management.
 
  Additional restructuring expense of $3,600 and $3,916 in 1993 and 1994,
respectively, principally relates to costs incurred for the relocation of the
data center from Orange, California, to Allen, Texas.
 
  The following summarizes the 1995 restructuring reserve activity:

J. RELATED PARTY TRANSACTIONS
 
   TRW REDI entered into trademark agreements with its partners, which require
the payment to each partner of a fee equal to 1% of the net sales price (as
defined) of services sold by TRW REDI for a five year period which commenced
September 1, 1991. Expenses under the agreements for the years ended December
31, 1993, 1994 and 1995 were $2,079, $1,945 and $1,845, respectively. At
December 31, 1994 and 1995, $349 and $1,000, respectively, are payable to TRW,
and $201 and $199, respectively, are payable to the minority partner of TRW
REDI, which represents trademark expense and other obligations of TRW REDI.
 
   Under the terms of a Cash Management and Loan Agreement with TRW, TRW REDI
has an overdraft line of credit of $8,000 to June 30, 1996, reduced to $5,000
to January 1, 1997 and $4,000 to December 1, 1997. The interest rate is the
30-day commercial paper rate plus 1%. The balance outstanding at December 31,
1995 was $4,859.
 
   Other assets at December 31, 1995 include an investment in VR Limited
Partnership ("VRLP") of $195. TRW REDI leases office space from VRLP through
an operating lease. During 1994 and 1995, TRW REDI paid rent of $62 and $165,
respectively, to VRLP.
 
   Certain of the units in the combined financial statements participate in
TRW's cash management system, under which TRW withdraws daily the unit's cash
receipts and covers any disbursements that have cleared the bank.
 
   TRW Corporate incurs general and administrative expenses that relate to all
of TRW's operating units, which are allocated based upon each operating unit's
cost of operations. TRW IS&S recorded these expenses with an offsetting entry
to the net investment account after related income taxes. Group Staff expenses
are included in cost of sales and administrative and selling expenses for
financial statement presentation purposes and were $12,405, $11,463 and
$10,171 in 1993, 1994 and 1995, respectively.
 
K. COMMITMENTS AND CONTINGENCIES
 
   TRW IS&S paid $565 in 1995, which was accrued at December 31, 1994, to
settle two shareholder derivative actions. The payment represented plaintiffs'
attorneys' fees. The settlement includes the adoption of certain therapeutic
measures involving the oversight of the consumer credit reporting business.
 
   TRW IS&S terminated two credit bureau contracts with certain plaintiffs as a
result of a merger. Plaintiffs filed suit alleging that TRW IS&S breached the
bureaus' contracts by retaining and using the credit information owned by the
bureaus after the contracts expired. TRW IS&S won the liability phase at
trial. The judgment was subsequently reversed by the appellate division and
the case was remanded for a trial on damages. TRW IS&S has accrued $600 at
December 31, 1994 and 1995. Trial is scheduled for June 1996. While the
ultimate outcome of the litigation cannot be determined, management does not
expect that this matter will have a material adverse effect on the combined
financial position of TRW IS&S.
 
   A plaintiff contends that TRW IS&S breached a commercial lease by failing to
restore the premises to its pre-occupancy condition and by holding-over after
the termination of the lease. The court found that TRW IS&S breached the lease
and that TRW IS&S owed the landlord double rent. The court found in favor of
the Plaintiff for $446, including pre-judgment interest, which was accrued at
December 31, 1994 and 1995. Plaintiffs have demanded $2,000 to settle. This
judgment was affirmed on appeal. TRW IS&S will petition the Supreme Court of
New Jersey for review of the judgment.

K. COMMITMENTS AND CONTINGENCIES--(CONTINUED)
 
  TRW IS&S is subject to various other legal proceedings and claims that arise
in the ordinary course of its business activities. Management believes that
any liability that may ultimately result from the resolution of these matters
will not have a material adverse effect on the combined financial position or
results of operations of TRW IS&S.
 
L. EVENT SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS REPORT [UNAUDITED]
 
  In February 1996, TRW entered into an agreement to sell substantially all of
TRW IS&S. The sale is subject to corporate and regulatory approval and other
conditions. Subsequent to the sale, TRW will maintain 19.6% of the voting
power of Holdings.

                      TRW INFORMATION SYSTEMS & SERVICES
 
               NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS
 
                            MARCH 31, 1995 AND 1996
                            (THOUSANDS OF DOLLARS)
 
A. BASIS OF PRESENTATION
 
  These combined financial statements of TRW Information Systems & Services
(TRW IS&S) include: TRW Information Services, TRW Business Credit Services and
IS&S Staff, which are divisions of TRW Inc. (TRW); IS&S International, Inc.,
Hotel Management Inc. and Information Systems and Services, Inc., which are
wholly-owned subsidiaries of TRW; and TRW REDI Property Data (TRW REDI), in
which TRW owns a 60% partnership interest. All significant intragroup accounts
and transactions have been eliminated in combination. The combined financial
statements exclude certain operating units historically included in TRW's
Information Systems & Services business segment.
 
  TRW IS&S operates in a single line of business, substantially all of which
is domestic--the sale of consumer and business information--organized along
three product lines: Consumer Information Services, Business Information
Services, and Real Estate Information Services. Consumer Information Services
provides consumer credit reports to retailers, financial organizations, and
other credit-granting organizations. Business Information Services provides
business credit decision support and demographic information for business-to-
business credit granting and direct marketing efforts to retailers and other
credit-granting organizations. Real Estate Information Services provides
property data services and title information services to title companies,
appraisers, and real estate brokers.
 
  The accompanying condensed combined financial statements have been prepared
by TRW IS&S without audit; however, in the opinion of TRW IS&S, the
accompanying condensed combined financial statements include all adjustments
(which are of a normal and recurring nature) necessary for a fair presentation
of the results for the interim periods. The condensed combined results for any
interim period may not be indicative of the results for the entire year. These
interim condensed combined financial statements should be read in conjunction
with the financial statements for the years ended December 31, 1993, 1994 and
1995.
 
B. RECAPITALIZATION TRANSACTION
   
  As more fully described in "The Recapitalization, Financing and Related
Transactions" section of the Registration Statement on Form S-1 of Experian
Information Solutions, Inc., a Recapitalization Agreement was entered into as
of February 9, 1996 among TRW, certain TRW subsidiaries and a Delaware
corporation owned by certain Investors, as defined. As a result of the
Recapitalization and certain other Transactions, as defined, Experian
Information Solutions, Inc. will merge into IS&S and is expected to change its
name to Experian Information Solutions, Inc.     
 
C. INVESTMENT IN COMCRED
 
  TRW IS&S has invested in Comcred S.A. de CV ("Comcred"), a start-up Mexican
credit data company. TRW IS&S purchased 2,400 shares of Comcred's Series B
stock (20% interest) for $750. TRW IS&S has entered into three note agreements
which allow Comcred to draw down cash as necessary. As of December 31, 1995
and March 31, 1996, TRW IS&S has principal and interest totaling $4,518 and
$4,572, respectively, outstanding under the notes. Two of the promissory notes
have conversion features which allow TRW IS&S to convert an amount of
principal and interest that would result in issuance of an additional 29% of
Comcred's total voting securities. TRW IS&S accounts for its investment in
Comcred using the equity method of accounting. During the three months ended
 
                                     F-23

                      TRW INFORMATION SYSTEMS & SERVICES
 
         NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS--(CONTINUED)
March 31, 1996, the Company provided an allowance of $968, before tax, related
to the notes described above. Through March 31, 1996 TRW IS&S has recorded
$1,000 of losses reflecting its share of the inception to date losses of
Comcred.
 
D. ACCOUNTING STANDARDS
 
  The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 121 (SFAS No. 121), Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of. SFAS No. 121
establishes accounting standards for determining the impairment of long-lived
assets to be held and used, certain identifiable intangibles, and goodwill
related to those assets and for long-lived assets and certain identifiable
intangibles to be disposed of. TRW IS&S adopted the provisions of SFAS No. 121
during the first quarter of 1996 and it did not have an effect on the
financial condition or results of operations.
 
E. COMMITMENTS AND CONTINGENCIES
 
  TRW IS&S terminated two credit bureau contracts with certain plaintiffs as a
result of a merger. Plaintiffs filed suit alleging that TRW IS&S breached the
bureaus' contracts by retaining and using credit information owned by the
bureaus after the contracts expired. TRW IS&S won the liability phase at
trial. The judgment was subsequently reversed by the appellate division and
the case was remanded for a trial on damages. As a result, TRW IS&S had
accrued $600 as of December 31, 1995 and March 31, 1996. Trial is scheduled
for June 1996. While the ultimate outcome of the litigation cannot be
determined, management does not expect that this matter will have a material
adverse effect on the Company.
 
F. OTHER MATTERS
 
  In February 1996, TRW entered into an agreement to sell substantially all of
TRW IS&S. The sale is subject to corporate and regulatory approval and other
conditions. Subsequent to the sale, TRW will maintain 19.6% of the voting
power of Holdings.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law ("DGCL") provides that a
corporation may 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 or investigative (other than an action by
or in the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, 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 him in connection with
such action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor, against expenses actually and
reasonably incurred in connection with the defense or settlement of such
action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and
except that 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 such other 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 Court of Chancery or such
other court shall deem proper.
 
  Section 102(b)(7) of the DGCL permits a corporation to include in its
certificate of incorporation a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such
provision shall not eliminate or limit the liability of a director (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174
of the DGCL (relating to unlawful payment of dividends and unlawful stock
purchase and redemption) or (iv) for any transaction from which the director
derived an improper personal benefit.
 
                                     II-1

  The Certificate of Incorporation of Experian provides that its Directors
shall not be liable to the Company or its stockholders for monetary damages
for breach of fiduciary duty as a director, except to the extent that
exculpation from liabilities is not permitted under the Delaware General
Corporation Law as in effect at the time such liability is determined. The
Certificate of Incorporation of Experian further provides that it shall
indemnify its directors and officers to the full extent permitted by the laws
of the State of Delaware.     
 
  After consummation of the Recapitalization, the Company, as survivor of the
IS&S Merger, will be incorporated under the laws of the State of Ohio. Ohio
Revised Code Section 1701.13 (E) provides that a corporation may indemnify or
agree to 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, other
than an action by or in the right of the corporation, by reason of the fact
that he is or was a director, officer, employee, or agent of the corporation,
or is or was serving at the request of the corporation as a director, trustee,
officer, employee, member, manager, or agent of another corporation, domestic
or foreign, nonprofit or for profit, a limited liability company, or a
partnership, joint venture, trust, or other enterprise, against expenses,
including attorney's fees, judgments, fines, and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit,
or proceeding, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
and, with respect to any criminal action or proceeding, if he had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit, or proceeding by judgment, order, settlement, or conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create
a presumption that the person did not act in good faith or in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, he had
reasonable cause to believe that his conduct was unlawful.
 
  The Company's Articles of Incorporation will provide the Company with the
power to indemnify its present and past directors, officers, employees and
agents to the full extent permitted under, and subject to the limitations of,
Title 17 of the Ohio Revised Code.
 
  The Stockholders Agreement is expected to provide for indemnification of
each of the Registrant's directors and officers in certain circumstances.
 
  The Company will purchase a Directors and Officers Liability Insurance
Policy for certain losses arising from certain claims and charges, including
claims and charges under the Securities Act, which may be made against such
persons while acting in their capacities as directors and officers of the
Company.

ITEM 17. UNDERTAKINGS
 
  (a) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Company pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Company of expenses incurred or paid by a director, officer or controlling
person of the Company 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 Company 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 Act
and will be governed by the final adjudication of such issue.

        (iii)  "Net Working Capital" means the account balance of those 
                current assets of Holdings on a consolidated basis less the
                account balance of those current liabilities of Holdings on a

                "Closing-Assumed Liability" account, but excluding those
                accounts identified as a "Closing-Excluded Assets" account or a
                "Closing-Excluded Liabilities" account (and excluding those

                from the acquisition of the remaining 40% interest in the REDI
                partnership.

(c) Closing Audit:  Promptly after the Closing, TRW will cause Ernst &
    Young LLP (the "Auditors"), independent certified public accountants, to
    conduct an audit of the Net Working Capital on Closing Date and the Approved
    Investments. Within ninety (90) days after the Closing, the Auditors will
    deliver to Operating Company and TRW a report (the "Auditors' Report") based
    on the audit stating the amount of the Net Working Capital and the Approved
    Investments reflected on the books of the Business as of the Closing in
    accordance with the Supplemental Accounting Principles described in Appendix
    E-2. Operating Company, if it so elects, will have the right to have its own
    independent certified public accountants or internal auditors observe the
    audit to be conducted by the Auditors.

(d) Review by Operating Company:  Following receipt of the Auditors'
    Report, Operating Company will be afforded a period of thirty (30) days to
    review the Auditor's Report (the "Review Period"). Operating Company will be
    deemed to have accepted the entire Auditors' Report unless, prior to the
    expiration of the Review Period, Operating Company delivers to TRW and the
    Auditors written notice and a detailed written explanation of those items in
    the Auditors' Report which Operating Company disputes, in which case the
    Auditors' Report and the items identified by Operating Company will be
    deemed to be in dispute. Within a further period of thirty (30) days from
    the end of the Review Period, the parties will attempt to resolve in good
    faith any disputed items. Failing such resolution, the unresolved disputed
    items will be referred for final binding resolution to the firm of Arthur
    Andersen & Co. The items of Net Working Capital and Approved Investments
    affected by such unresolved disputed items (if any) will be deemed to be as
    determined by such firm in accordance with the Supplemental Accounting
    Principles described in Appendix E-2 within thirty (30) days of such
    reference. One half of the cost of the determination by Arthur Andersen &
    Co. will be paid by Operating Company and one half by TRW. The decision of
    Arthur Andersen

                                      -14-

    & Co. will be final and binding on the parties and will not be subject to 
    appeal or challenge for any reason.

          2.9.  Payment of Adjustment:  The Adjustment will be paid as follows:

(a) If the Adjustment is a positive amount, Operating Company will pay
    Microwave the amount of the Adjustment, together with interest thereon
    (compounded monthly) at an annual rate equal to the Prime Rate for the
    period from the Closing Date through and including the date on which the
    Adjustment is paid, such payment to be made within ten (10) business days
    after the final determination of the Adjustment.

(b) If the Adjustment is a negative amount, then TRW will cause Microwave to
    refund to Operating Company the amount of the Adjustment together with
    interest thereon (compounded monthly) at an annual rate equal to the Prime
    Rate for the period from the Closing Date through and including the date on
    which the Adjustment is paid, such payment to be made within ten (10)
    business days after the final determination of the Adjustment.

(c) Any payment of the Adjustment will be treated for tax purposes as an
    adjustment to the Demand Note.

          2.10.  Method of Payment of Adjustment:  Payments of the Adjustment
will be made by delivery to the payee upon the prior request of the payee, by
depositing, by bank wire transfer, the required amount (in immediately available
funds) in an account of the payee, which account will be designated by the payee
for such purpose at least five (5) business days prior to the date of the
required payment.

          2.11.  No Set Off:  The obligation of Microwave or Operating Company,
as the case may be, to pay the Adjustment as determined in accordance with the
provisions of Section 2.8 hereof will be absolute and unconditional and will not
be affected by any circumstance, including, without limitation, any set off,
counterclaim, recoupment, defense (other than payment itself), or other right
which either party may have or allege to have against the other for any reason
whatsoever.

          2.12.  Real Estate Conveyance:  TRW's conveyance of the owned real
estate included as part of the Acquired Assets will be carried out as follows:

(a) Title Insurance Commitment:  Prior to the Closing, TRW will obtain or will 
    cause to be obtained a commitment from a nationally-recognized title
    insurance company (the "Title Company"), with a copy to Purchaser, that the

    parcels of real property will execute and deliver to the Title Company for
    safekeeping a limited warranty deed conveying and warranting title to such
    real estate to be free and clear of all liens and encumbrances created by,
    through or under such owner, subject to the Exceptions and to minor
    encroachments which, in the aggregate, do not have a significant effect on
    the marketability of such real estate, together with such affidavits,
    certificates, and other instruments as are ordinarily delivered to a
    purchaser of real estate or filed in the public records of the county in
    which the property is located.

(c) Instructions:  At the time such limited warranty deeds are delivered to the
    Title Company, TRW, the owners of the real property and Purchaser will
    deliver to the Title Company a joint letter instructing the Title Company to
    hold such warranty deed until the Closing and, at the Closing:

          (2)  otherwise, to return such limited warranty deed to TRW.

    warranty deed for record, then such warranty deed will be deemed to have 
    been filed as of the close of business on the Closing Date.

    premium in respect of the Owner's Policy of Title Insurance described in
    Section 2.12(a) hereof.

agreement with the terms set forth in Annex P hereto; provided, however, that at
the request of the Purchaser made prior to the Closing, TRW agrees to negotiate
in good faith to make such modifications to such form of Transition Agreement as
may be required to provide for the provision by TRW, at a cost equal to TRW's
internal cost, of such additional services currently provided to the Business as
the parties may agree for such reasonable period as the parties may mutually
agree upon.

      4.5.  Consents to Assignment:  Between the date of this Agreement and
the Closing, TRW will use all reasonable efforts to obtain, and will cause each
member of the TRW Group to use all reasonable efforts to obtain, the consents or
approvals (or effective waivers thereof) of assignment from those persons whose
consents or approvals are required for the assignment of TRW's rights under
those contracts, leases, licenses, permits, approvals and other items included
in the Acquired Assets identified on Appendix G hereto.  TRW further covenants
to Purchaser that, between the date of this Agreement and the Closing, TRW will
use all reasonable efforts to obtain, and will cause each member of the TRW
Group to use all reasonable efforts to obtain, the consents or approvals (or
effective waivers thereof) of other persons whose consents or approvals are
required for the assignment of TRW's rights under other contracts, leases,
licenses, permits, approvals and other similar items constituting part of the
Acquired Assets.  Failure of the TRW Group to obtain, after a good faith attempt
and use of all reasonable efforts, the consents or approvals described in this
Section 4.5 will not give rise to monetary damages against TRW.

exchanging such information and providing such assistance as the other may
reasonably request in connection with the foregoing and in seeking early
termination of any applicable waiting periods under the HSR Act or in connection
with other regulatory approvals and consents.  Each of TRW and Purchaser agrees

its representatives, on the one hand, and any governmental agency or authority
or members of their respective staffs, on the other hand, with respect to this
Agreement and the transactions contemplated hereby.

      4.7.  Consent Orders and Assurances of Discontinuance:  Between the
date of this Agreement and the Closing, the parties will cooperate fully with
each other in obtaining a release of TRW effective as of the Closing Date from

the reasonable judgment of the party may be required by law or in connection
with the obligations of a publicly-held, exchange-listed company, in which case
the language of any such report, statement or press release will, to the extent
practicable, be mutually agreed to by the parties, which agreement will not be
unreasonably withheld.

      4.9.  Exclusivity:  During the term of this Agreement, TRW will not,

any of its component corporations or partnerships.  TRW represents that neither

action to cause such entities to amend their respective articles of
incorporation to change their names to the names so designated by Purchaser as
of or prior to the Closing.

                Purchase Price that TRW will have no obligations with respect to
                the placement of bank debt or debt securities and (y) will have
                included provisions to that effect in any terms of any such debt
                placement; and

        (k)     Purchaser, Holdings, Operating Company and TRW will have entered
                into an agreement reasonably satisfactory to TRW pursuant to
                which Holdings and Operating Company will indemnify, defend and

                controlling persons and agents from and against any and all
                liabilities, damages, losses, claims, costs and expenses

                                  ARTICLE VI

                                  Tax Matters

        6.1.    Characterization of Transaction and Reporting of Purchase Price:
The parties hereto recognize that the transactions that are contemplated by this
Agreement constitute a fully taxable sale for all Tax purposes of all of the
assets of the Business. The parties hereto agree to allocate the Purchase Price
(and all other capitalized costs) plus liabilities assumed to the Acquired
Assets, for all Tax purposes based upon the relative fair market value of such
assets as determined by an independent appraisal to be obtained by Purchaser at
its expense; provided, however, that the parties hereto agree that the Trademark
License will be valued at $26 million and the tangible assets in California will
be valued at their net book value as detailed on Schedule 6.1 hereto and

                                     -35-
<PAGE>
 
no value is assigned to the covenant not to compete.  Except as provided below
in this Section 6.1, it is the intention of the parties that TRW will accept
liability for and pay any and all Taxes of the TRW Group due for or attributable
to Tax periods ending on or before the Closing Date and that portion related to
the operation of the Business on or prior to the Closing Date for any Tax period
ending after the Closing Date.  It is the intention of the parties that the TRW
affiliated group (other than the Transaction Companies) will accept liability
for and pay any and all Taxes attributable to the transfer of Acquired Assets by
TRW and Microwave to Operating Company. It is the intention of the parties that
the TRW affiliated group (other than the Transaction Companies) will accept
liability for and pay all Taxes for any Transaction Companies attributable to
the deemed sale of assets pursuant to the Section 338(h)(10) Election; provided,
however, for those state jurisdictions which do not respect or allow the Section
338(h)(10) Election, the TRW affiliated group (other than the Transaction
Companies) will pay Taxes on the sale of stock, but its obligations to pay Taxes
on the deemed asset sale under the Section 338(h)(10) Election will be reduced
correspondingly.  Thus, it is the intention of the parties that the TRW
affiliated group's gain from the transactions contemplated in this Agreement
will be subject to Tax only once for any state or local purposes.  The following
provisions are intended to effectuate these principles and will be interpreted
by the parties in a manner consistent with these principles.

        6.2.    Tax Returns:

        (a)     TRW will file with the appropriate taxing authorities all Tax
                Returns required to be filed on its behalf and on behalf of the
                Partnership and the Transaction Companies for any taxable period
                ending on or before the Closing Date, and TRW will include the
                taxable income of the Partnership and the Transaction Companies
                (to the extent permitted by law) for each such period in its
                consolidated federal income Tax Return and in any consolidated,
                combined or unitary Tax Return (including Tax Returns based on
                or measured by net income) filed by TRW or any affiliate thereof
                in which such income can be included under applicable state or
                local law. Each Transaction Company will furnish Tax information
                to TRW for inclusion in such consolidated, combined or unitary
                Tax Returns filed by TRW or an affiliate thereof for the period
                which includes the Closing Date in accordance with such
                corporation's past custom and practice and TRW will make a
                reasonable effort to notify the Transaction Company if it
                utilizes the Tax information in a manner inconsistent with the
                manner in which it is provided. TRW and its affiliates will take
                no position on such Tax Returns that relate to any Transaction
                Company or any of its subsidiaries that is inconsistent with
                each of such entity's past custom and practice. TRW and its
                affiliates agree that they will take all actions necessary to
                treat the transactions contemplated by this Agreement as being a
                fully taxable sale of all of the assets of the Business pursuant
                to Section 338(h)(10) of the Code or otherwise and not subject
                to the anti-churning rules of Code Section 197(f)(9). TRW and
                its affiliates further agree that they will not take, or cause
                to be taken, any action which would be inconsistent with or
                prejudicial to the immediately preceding sentence.

                                     -36-
<PAGE>
 
        (b)     Holdings will cause the Transaction Companies to file with the
                appropriate taxing authorities all Tax Returns required to be
                filed by them for any taxable period ending after the Closing
                Date and will remit any Taxes due in respect of such Tax
                Returns. TRW will pay to Holdings the Taxes for which TRW is
                liable pursuant to Sections 6.1 and 6.3 hereof, but which are
                payable in respect of Tax Returns to be filed by Holdings
                pursuant to this Section 6.2(b) within 10 business days prior to
                the due date (taking account of any extensions of time for
                filing) for the filing of such Tax Returns but no earlier than
                20 business days after such Tax Returns and the tax allocation
                calculations have been submitted to TRW for review and approval.

        (c)     TRW will not be obligated or responsible for filing any returns
                or amended returns to reflect any carrybacks of post-Closing net
                operating losses of the Transaction Companies.

        6.3.    Liability for Pre-Closing Taxes:  TRW will be liable for and
will pay, and hereby indemnifies, each Transaction Company for all Taxes,
including, but not limited to, Taxes resulting from the Transaction Companies
except Lusk ceasing to be members of the affiliated group (as defined in Section
1504(a) of the Code without regard to the limitations contained in Section
1504(d) of the Code) that includes TRW or any predecessors; Taxes imposed on any
person for any taxable year (a) under Treas.  Reg. (S)1.1502-6 (or any similar
provision of state, local or foreign law), (b) as a transferee or successor, or
(c) by contract in or otherwise; amounts pursuant to any guaranty,
indemnification, tax sharing, or similar agreement made on or before the Closing
Date relating to the sharing of liability for payment of Taxes; Taxes resulting
from the breach of any representation or warranty in Section 3.2(n) hereof
imposed on TRW, the Partnership or any Transaction Company, or for which any of
TRW, the Partnership, and the Transaction Companies may otherwise be liable;
Taxes imposed by reason of, attributable to, or resulting from the Section
338(h)(10) Election as set forth in Sections 6.1 and 6.5 hereof, and Taxes
resulting from transactions described in Sections 2.1(a) through 2.1(i) hereof,
for any taxable year ending on or prior to the Closing Date and for the portions
of such taxable year or period ending on or prior to the Closing Date (or, in
the case of consolidated, combined or unitary Tax Returns, including TRW, any
period including the Closing Date) and any costs and expenses (including,
without limitation, costs of collection and attorneys' fees) arising out of or
resulting from TRW's liability and indemnity for Taxes hereunder.  TRW will be
entitled to retain any refund of Taxes with respect to the Partnership and the
Transaction Companies relating to any such periods.  In order appropriately to
apportion any income Taxes relating to any taxable year or period that begins
before and ends after the Closing Date, the parties hereto will, to the extent
permitted by applicable law, elect with the relevant taxing authority to
terminate the taxable year as of the Closing Date (provided, however, that any
Taxes related to the Section 338(h)(10) Election will be determined as provided
in Section 6.1 and 6.5 hereof).  In any case where applicable law does not
permit any company to treat the Closing Date as the end of a taxable year of
such corporation, then whenever it is necessary to calculate the liability for
income or franchise
                                     -37-
<PAGE>
 
Taxes of such company for a portion of a taxable year, such determination will
(unless otherwise agreed to in writing by Holdings and TRW) be determined by a
closing of such corporation's books at the end of the Closing Date (provided,
however, that any Taxes related to the Section 338(h)(10) Election will be
determined as provided in Section 6.1 and 6.5 hereof), except that exemptions,
allowances or deductions that are calculated on an annual basis, such as the
deduction for depreciation, will be apportioned on a daily basis.  In order
appropriately to apportion any Taxes, other than income or franchise Taxes,
relating to any taxable year or period that begins before and ends after the
Closing Date, (i) ad valorem Taxes (including, without limitation, real and
personal property Taxes) will be accrued on a monthly basis over the period for
which the Taxes are levied, or if it cannot be determined over what period the
Taxes are being levied, over the fiscal period of the relevant taxing authority,
in each case irrespective of the lien or assessment date of such Taxes, and (ii)
franchise and other privilege Taxes not measured by income will be accrued on a
monthly basis over the period to which the privilege relates.

        6.4.    Tax Audits Relating to the Business:

        (a)     TRW will give notice to Holdings of any audits of or
                administrative or court proceedings relating to TRW's or any
                affiliate's consolidated, combined or unitary Tax Returns
                related to the operations of the Business for periods ending
                prior to the Closing Date, and will keep Holdings and its
                counsel informed of the progress of, and issues involved in, the
                same, all to the extent that such returns relate to the
                Partnership or the Transaction Companies. TRW will be entitled
                to control the defense of any such audits or proceedings.

        (b)     Holdings will give notice to TRW of any Tax claim relating to
                any taxable year or period that includes the Closing Date, and
                will keep TRW and its counsel informed of the progress of, and
                the issues involved in, the same, in each case which may be the
                subject of indemnification by TRW pursuant to this Agreement.
                Holdings will be entitled to control the defense and resolutions
                of any such audits or proceedings; provided, however, that if
                any Transaction Company settles any Tax claim for the portion of
                a taxable year or period ending on or prior to or after the
                Closing Date or including the Closing Date which may be the
                subject of indemnification by TRW pursuant to this Agreement
                without the prior written consent of TRW, which consent will not
                be unreasonably withheld, TRW will be released from any
                indemnification obligations hereunder.

        6.5.    Code Section 338(h)(10) Election and Code Section 197(f)(9)(B):
TRW agrees to join with Holdings in making an election under Section 338(h)(10)
of the Code (and any corresponding elections under state, local, or foreign tax
law) (collectively, a "Section 338(h)(10) Election") with respect to the actual
or deemed purchase and sale of the stock of Operating Company, TRW Hotel and
Lusk.  TRW will pay any Tax, including any federal, foreign, state and local
Taxes, whether determined on a consolidated, combined, unitary, separate or
other return basis, attributable to, arising out of or resulting from the making
of the Section 338(h)(10)
                                     -38-
<PAGE>
 
Election in accordance with Section 6.1 hereof and will indemnify the
Partnership and the Transaction Companies against any Taxes arising out of any
failure to pay such Tax.  TRW will also pay any state, local, or foreign Tax
(and indemnify the Partnership and the Transaction Companies against any Taxes
arising out of any failure to pay such Tax) attributable to an election under
state, local or foreign law similar to the election available under Section
338(g) of the Code (or which results from the actual or deemed making of an
election under Section 338(g) of the Code) with respect to the actual or deemed
purchase and sale of the stock of the Transaction Companies hereunder where the
state, local, or foreign tax jurisdiction does not provide or recognize a Code
Section 338(h)(10) Election.  Notwithstanding the above, TRW's obligations
hereunder will be reduced with respect to the state Taxes on the deemed sale of
assets under Section 338(h)(10) Election in any state, where both (i) TRW or
Microwave actually recognizes gain on the sale of Operating Company stock to
Holdings that is taxed in that state and (ii) such state does not recognize the
Section 338(h)(10) Election, by the amount of Taxes paid with respect to the
sale of stock in Operating Company in that particular state.  In addition, TRW
will pay that portion of any income or similar Tax for the Transaction Companies
(including Taxes in Texas and Ohio) due for a Tax period ending after the
Closing Date to the extent such Tax is measured by gain or income recognized on
account of the Section 338(h)(10) Election or the transfer of Acquired Assets.
TRW and its affiliates will comply fully with all filing and other requirements
necessary to effect the Section 338(h)(10) Election.  In addition, at the
request of Holdings), TRW and its affiliates will make an election under Code
Section 197(f)(9)(B) in connection with the Transactions contemplated by this
Agreement.

        6.6.    Cooperation Regarding Tax Matters:  The parties hereto will
provide such necessary information as any other party hereto may reasonably
request in connection with the preparation of such party's Tax Returns, or to
respond to or contest any audit, prosecute any claim for refund or credit or
otherwise satisfy any legal requirement relating to Taxes of each party hereto
or their respective affiliates.

        6.7.    Tax Sharing Agreements:  All Tax sharing agreements, policies,
arrangements and practices between TRW or any of its affiliates and the
Partnership or the Transaction Companies will terminate as of the Closing Date
and will have no further effect for any taxable year (whether the current year,
a future year, or a past year).  TRW and its affiliates on the one hand and the
Partnership and each of the Transaction Companies on the other will cancel any
intercompany accounts in respect of Taxes with each other as of the Closing Date
as provided in Section 4.10 hereof.  Any powers of attorney with respect to
Taxes of the Partnership or the Transaction Companies currently in force will be
terminated effective as of the Closing.

        6.8.    Payment of Transfer Taxes and Other Charges:  TRW will pay all
transfer Taxes, if any, including, but not limited to, sales, use, and value
added Taxes due on account of the Recapitalization transactions described in
this Agreement.  Purchaser and the Transaction Companies assume responsibility
for and will pay any and all Taxes, fees and assessments due to or attributable
to actions following the Recapitalization transactions including, but not
limited to, filing fees, franchise Taxes, license fees or other costs for
qualification or
                                     -39-
<PAGE>
 
registration of, or for registration of shares of, TRW Hotel, Holdings,
Operating Company, Comcred, S.A. de C.V., Servicred, S.A. de C.V., Lusk and CCB
in any state or local jurisdiction, or any foreign jurisdiction including,
without limitation, costs or fees, if any, to register or file articles or
certificates or amended articles of incorporation with or to qualify to do
business in any state or local jurisdiction.

        6.9.    Survival of Obligations, Etc.:  The obligations of the parties
set forth in this Article VI relating to Taxes will, except as otherwise agreed
in writing, be unconditional and absolute and will remain in effect without
limitation as to time or amount of recovery by any party hereto until thirty
(30) days after the expiration of the applicable statute of limitations
governing the Tax to which such obligations relate (after giving effect to any
agreement extending or tolling such statute of limitations).

        6.10.   Other:  Any indemnification payments or Adjustment to the
Purchase Price made under this Agreement will be treated for Tax purposes as an
adjustment to the Demand Note portion of the Purchase Price paid to Microwave by
Operating Company.

                                 ARTICLE VII

                             Actions After Closing

        7.1.    Further Conveyances:  After the Closing and without further cost
or expense to the Transaction Companies, TRW will execute and deliver to the
Transaction Companies such additional instruments of conveyance and take such
other and further actions as Operating Company may reasonably request, and as
are ordinarily provided by a seller, more completely to sell, transfer and
assign to Operating Company and vest Ownership in the appropriate Transaction
Company to the Acquired Assets and to consummate the transactions contemplated
hereby.

        7.2.    Further Consents to Assignment:  As and to the extent any member
of the TRW Group  will have failed to obtain prior to Closing the consent or
approval (or an effective waiver thereof) of any person or persons in respect of
any item described in Section 4.5 hereof;

        (a)     the parties will fully cooperate with each other to obtain from
                such person or persons the consents or approvals (or effective
                waivers thereof);

        (b)     if the consent or approval is listed in Appendix G and is not
                obtained prior to the Closing, then (1) the members of the TRW
                Group will (x) use reasonable efforts to provide the Transaction
                Companies with an alternative arrangement providing the benefit
                of all the rights of the members of the TRW Group under such
                contract, lease, license, permit, approval or similar item
                including, without limitation, enforcement (at TRW's expense) of
                any and all rights of the members of the TRW Group against such
                person as the Transaction Companies may reasonably request

                                     -40-
<PAGE>
 
                and (y) indemnify and hold harmless the Transaction Companies
                from and against any and all liabilities, damages, losses,
                claims, costs and expenses (including, without limitation,
                attorneys' fees and expenses) arising out of or related to the
                failure to obtain such consent, approval or waiver; (2)
                Purchaser, in its good faith reasonable judgment, may elect to
                accept or reject such proposed alternative arrangement; and (3)
                if Purchaser elects to reject such proposed alternative (or if
                an alternative is not proposed), such election (or failure to
                propose an alternative) will be deemed to constitute, pursuant
                to Section 5.1 hereof, a failure to satisfy a condition to
                Purchaser's obligation to consummate the transactions
                contemplated by this Agreement, but will not constitute a breach
                of covenant or a breach of warranty by any member of the TRW
                Group; and

        (c)     if the parties are unable to obtain any consent or approval (or
                effective waiver thereof) under any of the contracts, leases,
                licenses, permits, approvals or other similar items constituting
                part of the Acquired Assets that are not listed in Appendix G,
                then after the Closing (1) this Agreement will not constitute or
                be deemed to be a contract to assign the same if an attempted
                assignment without such consent, approval or waiver would
                constitute a breach of such item or create in the issuer or any
                party thereto the right or power to cancel or terminate such
                item and, in such case, the consummation of the transactions
                contemplated hereby will not be deemed to constitute such an
                assignment and (2) TRW, IS&S International and Microwave will
                use reasonable efforts to cooperate with the Transaction
                Companies in any reasonable arrangement designed to provide the
                Transaction Companies with the benefit of all the rights of the
                members of the TRW Group under such contract, lease, license,
                permit, approval or similar item, including, without limitation,
                enforcement (at TRW's expense) of any and all rights of the
                members of the TRW Group against such person as the Transaction
                Companies may reasonably request.

        7.3.    Access to Former Business Records: For a period of ten (10)
years following the Closing, or until any audits of the Tax Returns of the TRW
Group relating to periods prior to the Closing are completed, whichever occurs
later, Operating Company will retain all business records of the Business other
than those records destroyed in accordance with normal record retention
procedures. During such period, Operating Company will afford duly authorized
representatives of TRW or an appropriate tax auditor displaying appropriate
credentials free and full access to all of such records and will permit such
representatives, at TRW's expense, to make abstracts from, or to take copies of
any of such records or to obtain temporary possession of any thereof as may be
reasonably required by TRW. During such period, Operating Company will cooperate
with TRW or an appropriate tax auditor, and cause employees of the Business to
cooperate with TRW or an appropriate tax auditor, at TRW's expense, in
furnishing information, evidence, testimony and other assistance in connection
with any action, proceeding or investigation relating to TRW's conduct of the
Business prior to the Closing. If Operating Company desires to dispose of any
such records prior to the expiration of such period other than

                                     -41-
<PAGE>
 
in accordance with normal record retention procedures, Operating Company will,
prior to such disposition, give TRW the opportunity, at TRW's expense, to
segregate and remove such records as TRW may select.

        7.4.    Access to Former Employees: After the Closing, Operating Company
will make available to TRW any employees of Operating Company whom TRW may
reasonably need in order to defend or prosecute any legal or administrative
action to which TRW is a party and which relates to the conduct of the Business
prior to the Closing. TRW will pay or reimburse Operating Company for all
reasonable expenses which may be incurred by such employees in connection
therewith, including, without limitation, all travel, lodging and meal expenses,
and TRW will compensate Operating Company for the number of whole business days
spent by each such employee in providing such services at the rate of one
hundred thirty percent (130%) of the average daily gross pay per business day
(excluding the value of employee benefits) of such employee during the calendar
month in which such services are performed.


        7.5.    Use of TRW Trademark: The Transaction Companies will not use 
the TRW name or Trademark, except as authorized in accordance with the Trademark
Agreement.

        7.6.    Nondisclosure:

        (a)     For a period of five (5) years after the Closing, TRW will not,
                and will cause each of its affiliates, and their respective
                successors and assigns not to, (i) use any Confidential
                Information (as hereinafter defined) for its own benefit or the
                benefit of any person, firm or corporation other than the
                Transaction Companies and their respective successors and
                assigns, or (ii) disclose any Confidential Information to any
                person, firm or corporation, other than to (x) the Transaction
                Companies and their respective successors and assigns or (y)
                entities controlled by TRW. The term "Confidential Information"
                will mean any trade secrets, any confidential or proprietary
                information and any tangible items which record such trade
                secrets or confidential or proprietary information that TRW or
                any of its affiliates has in its possession on or before the
                Closing Date concerning operations, inventions, developments,
                products, services, processes, discoveries or other matters
                relating to the Business, except for any information which (x)
                is or becomes publicly known or within the public domain other
                than as a result of disclosure by TRW or any of its affiliates
                in violation of the terms of this Agreement or (y) becomes
                available subsequent to the Closing to TRW or any of its
                affiliates on a non-confidential basis from a source other than
                the Transaction Companies, provided that such source is not
                prohibited from disclosing such information to TRW or any of its
                affiliates by a contractual, legal or fiduciary obligation to
                the Transaction Companies. The covenant set forth in this
                Section 7.6 will not be applicable to TRW's use of any
                information concerning the Business in connection with (i) the
                payment or contesting of any Excluded Liability or (ii) the
                preparation and publication of TRW's financial statements and
                all reports and disclosures provided

                                     -42-
<PAGE>
 
                for in the Securities Act of 1933, as amended, and the
                Securities Exchange Act of 1934, as amended, and the respective
                regulations thereunder.

        (b)     In the event that TRW or any of its affiliates receives a
                request or is required (by deposition, interrogatory, request
                for documents, subpoena, civil investigation or similar process)
                to disclose any or all of the Confidential Information, TRW
                agrees to (i) provide Operating Company with prompt notice of
                the existence, terms and circumstances surrounding such a
                request, (ii) consult with Operating Company on the advisability
                of taking legally available steps to resist or narrow such
                request, and (iii) provide reasonable assistance to Operating
                Company, at Operating Company's expense, in seeking a protective
                order or other appropriate remedy. In the event that a
                protective order or other remedy is not obtained or that
                Operating Company waives compliance with the provisions hereof,
                (i) the entity which received such a request may disclose only
                that portion of the Confidential Information which it is advised
                by opinion of its counsel is legally required to be disclosed
                and will cooperate with Operating Company in seeking to obtain
                reasonable assurance confidential treatment will be accorded to
                such portion of the Confidential Information, and (ii) such
                entity will not be liable for such disclosure unless such
                disclosure to any such tribunal was caused by or resulted from a
                previous disclosure by TRW or any of its affiliates not
                permitted by this Section 7.6.

        (c)     The parties further agree that damages at law for violation of
                the foregoing covenant would not be an adequate or proper remedy
                and that, if TRW or any of its affiliates violates or threatens
                to violate the foregoing covenant, the Transaction Companies and
                their respective successors and assigns will be entitled, upon
                application to a court of competent jurisdiction and notice to
                TRW, to obtain a temporary or permanent injunction, without the
                posting of any bond, against TRW or any of its affiliates
                prohibiting any threatened or further violation of this
                covenant, and also to seek damages, compensatory, exemplary or
                otherwise, for such violation. Such remedies will not be deemed
                to be the exclusive remedies for a breach of this Section 7.6
                available to the Transaction Companies and their respective
                successors and assigns, but will be in addition to any and all
                other remedies available at law or in equity.

                                 ARTICLE VIII

                        Employees and Employee Benefits

        8.1.    Employment of Initial Employees: Reasonably in advance of the
Closing, Purchaser will offer to substantially all TRW Employees and all
Partnership Employees employment with Operating Company effective as of the
Closing, with initial job responsibilities and cash compensation comparable in
the aggregate to those extended to such employees by TRW

                                     -43-
<PAGE>
 
or the Partnership, as the case may be.  TRW will use all reasonable efforts to
assist Purchaser in making arrangements for Operating Company to hire the TRW
Employees and the Partnership Employees (other than those who elect to retire)
as of the Closing.  Effective as of the Closing, all TRW Employees and all
Partnership Employees who accept Purchaser's offer of employment will become
employees of Operating Company ("Hired Employees").  Purchaser may identify up
to ten (10) individuals who will not become Hired Employees as of the Closing
but who will remain employees of TRW and provide services to Operating Company
on such terms and conditions (not less favorable to such individuals than the
terms and conditions of their current employment) as Purchaser and TRW may
agree.  TRW and its subsidiaries will neither employ nor offer employment to any
Hired Employee during the twelve (12) month period following the Closing without
the prior written consent of Operating Company.  During such period, Holdings
and its subsidiaries will not, without the prior written consent of TRW, employ
or offer employment to any former employee of the Business within six months of
such person's retirement under any applicable TRW pension plan.

        8.2.    Subsequent Terminations or Layoffs:  In any termination or
layoff by Operating Company of any Hired Employee after the Closing, Operating
Company will comply fully (where applicable) with the Worker Adjustment and
Retraining Notification Act of 1988 ("WARN") and all other applicable Federal,
state and local laws, including those prohibiting discrimination and requiring
notice.  The Operating Company will be solely responsible for any severance
expenses due a Hired Employee as a result of any such termination or layoff and
will bear the cost of compliance with (or failure to comply with) any such laws.
For six months after the Closing, Operating Company will maintain severance
benefits comparable to severance benefits in effect, immediately prior to the
Closing, for TRW Employees or Partnership Employees as the case may be.

        8.3.    Employee Benefits:  The Transaction Companies are not assuming
and will not have any responsibility for the continuation of any Plan maintained
by TRW for the Business, and no Plan adopted or maintained by Operating Company
with respect to the Business will be deemed a Successor Plan of TRW.  The
Operating Company will assume and maintain for the Partnership Employees for a
reasonable period of time (not less than three months) after the Closing all
employee benefit plans (which will include all employee pension benefit plans
and employee welfare benefit plans) in effect as of the Closing which covered
Partnership Employees, and Operating Company will be deemed a successor employer
to all such plans.  Without limiting the foregoing, TRW will be responsible for
any claims incurred prior to the Closing under any group health, disability,
life insurance or similar plan maintained by TRW.  For purposes of this Section
8.3, a claim will be incurred upon (a) the rendering of a covered service or the
commencement of hospitalization or confinement, in the case of a group health
plan, (b) the disabling event, in the case of a disability plan, and (c) death,
in the case of a life insurance plan.

        8.4.    Pension Plan:  TRW will retain all assets and liabilities in the
TRW Salaried Pension Plan (the "Pension Plan") allocable to the TRW Employees,
including all Hired Employees.  All benefit service and vesting service accruals
for the TRW Employees, including

                                     -44-
<PAGE>
 
the Hired Employees, under the Pension Plan will cease as of the Closing.  TRW
will amend the Pension Plan to provide those Hired Employees who (i) are covered
under the Pension Plan at the Closing, (h) have five or more years of vesting
service under the Pension Plan at the Closing and (iii) are employed by
Operating Company for at least one year from the Closing with a supplemental
benefit.  The supplemental benefit will be based upon the formula of 2.5% times
                                                                          -----
pensionable earnings times years of benefit service where "benefit service"
                     -----                                                 
means the benefit service credited to such Hired Employee under the Pension Plan
at the Closing and "pensionable earnings" (as defined in the Pension Plan but
limited to 1995 earnings only) means the 1995 pensionable earnings of such Hired
Employee.  The parties may agree to allocate among such Hired Employees the
aggregate amount of the supplemental benefit determined under such formula on a
basis weighted for age or benefit service.  The supplemental benefit will be
paid as a single sum payment upon receipt of a deferred vested benefit or
retirement benefit from the Pension Plan.  Both the vested Pension Plan benefit
and the supplemental benefit described herein will not be payable to the Hired
Employee until such employee has (i) attained at least age 55, (ii) terminated
employment from Operating Company (or any successor of Operating Company or
purchaser of substantially all of the Business) and (iii) filed a written
application therefore with the Pension Plan's Board of Administration. (Hired
Employees still employed with Operating Company (or successor) after attainment
of age 65 may file a written application for receipt of benefits from the
Pension Plan.)

        8.5.    Medical, Dental and Vision Benefits:  As of the Closing and
without any waiting period, Operating Company will provide all Hired Employees
(and their dependents) with medical, dental and vision benefit coverage under
group health plans maintained by Operating Company, which may include the
medical, dental and vision plans which cover Partnership Employees as of the
Closing and which are being assumed by Operating Company.  The Operating Company
will waive any pre-existing condition exclusions or limitations applicable to
such persons under such medical, dental and vision plans.

        8.6.    Life Insurance:  As of the Closing, Operating Company will
provide all Hired Employees with coverage under life insurance benefit plans
maintained by Operating Company, which may include the life insurance benefit
plans which cover Partnership Employees as of the Closing and which are being
assumed by Operating Company.

        8.7.    Vacation:  As of the Closing, Operating Company will assume an
obligations of TRW and the Partnership to Hired Employees for any accrued but
unused vacation days in accordance with the Supplemental Accounting Principles
set forth on Appendix E-1. TRW will have no obligation to make any payment to
Hired Employees after the Closing with respect to any such vacation days.

        8.8.    401(k) Plans:  TRW currently maintains the TRW Employee Stock
Ownership and Stock Savings Plan ("SSP") and the Partnership currently maintains
the TRW REDI Employee Savings Plan ("Partnership Plan"), both plans being
qualified under Sections 401(a) and 401(k) of the Code.  All contributions to
the SSP by TRW Employees and matching contributions by
  
                                   -45-
<PAGE>
 
TRW will cease as of the Closing.  The Operating Company will assume and
maintain the Partnership Plan with an employer matching contribution no less
than that in effect under the Partnership Plan at the Closing.  The Operating
Company agrees to either (i) cover all Hired Employees under the Partnership
Plan being assumed by Operating Company as of the Closing or (ii) establish,
effective as of the Closing, a 401(k) plan which will provide an employer
matching contribution at least equal to the employer matching contribution in
effect under the SSP at the Closing (the "Purchaser 401(k) Plan").  The
Purchaser 401(k) Plan will recognize service of Hired Employees rendered to TRW
and recognized by the TRW 401(k) Plan for all purposes for which service counts
under the Purchaser 401(k) Plan.  As soon as practicable thereafter, TRW and
Purchaser will agree in good faith on a valuation date ("Valuation Date").  On a
date as further agreed upon by the Purchaser and TRW after the Valuation Date,
TRW will (i) cause the interests of each TRW Employee in the Insured Return,
Equity, Bond Index and Small Company Equity Funds maintained pursuant to the SSP
to be liquidated into an amount of cash equal to the value of each such person's
interest in such fund as of the close of business on the Valuation Date; (ii)
cause the interests of each TRW Employee in the TRW Stock Fund maintained
pursuant to the SSP to be converted into shares of TRW Common Stock; and (iii)
cause the cash amounts and shares of TRW Common Stock as so determined to be
spun off and transferred to the Purchaser 401(k) Plan, once satisfactory
evidence of intended IRS qualification of the Purchaser 401(k) Plan has been
provided to TRW.

        8.9.    Workers' Compensation:  TRW will bear the entire cost and
expense of all workers' compensation claims arising out of injuries identifiably
sustained by Hired Employees before the Closing.  Operating Company will bear
the entire cost and expense of all workers' compensation claims arising out of
injuries and illnesses identifiably sustained by Hired Employees after the
Closing.  TRW will bear the entire cost and expense of all workers' compensation
claims arising out of injuries without an identifiable date of occurrence and
which are alleged to have arisen before the Closing and which are filed before
the Closing. Notwithstanding any state law to the contrary, Operating Company
will bear the entire cost and expense of all workers' compensation claims
arising out of injuries and illnesses sustained by Hired Employees without an
Identifiable date of occurrence and which are alleged to have arisen before or
after the Closing which are filed after the Closing.  From and after the
Closing, Operating Company will use its good faith efforts to facilitate the
return to work in the employment of Operating Company of any Hired Employee who
is on disability leave on the Closing as a result of a work-related injury or
illness.

        8.10.   No Rights:  No former, present or future employees of either
party (or any dependents of such employees) will be treated as third party
beneficiaries in or under this Agreement.  Except as provided in Section 8.2
hereof, nothing herein is to be construed to require the Transaction Companies
to maintain any benefit or condition of employment for a period longer than
three (3) months following the Closing.

effective as of the Closing, Operating Company is a successor employer of the
Hired Employees for purposes of compliance with the Family and Medical Leave
Act.

                                Indemnification

        9.1.    Indemnification of TRW:  Subject to the limitations set forth in
Section 9.5 hereof, each of the Transaction Companies hereby agrees and
covenants that after the Closing each will jointly and severally indemnify,
defend and hold TRW and its subsidiaries harmless from and against any and all
liabilities, damages, losses, claims, costs and expenses (including, without
limitation, costs of collection and reasonable attorneys' fees) arising out of
or resulting from (a) either (i) any misrepresentation or breach of warranty by
Purchaser for which notice is given by TRW within the applicable periods
specified in Section 3.5 hereof or (ii) any claim by a person other than TRW and
its subsidiaries, which claim is based upon one or more allegations that, if
true, would give rise to a right of indemnification under clause (a)(i) of this
sentence and for which notice is given by TRW within the applicable periods
specified in Section 3.5 hereof; (b) any failure to pay or satisfy or cause to
be paid or satisfied any of the Assumed Liabilities when due and payable; (c)
nonperformance by Purchaser of any obligation to be performed on the part of the
Purchaser under this Agreement prior to the Closing and the non-performance by
any of the Transaction Companies of any obligation to be performed on their
respective parts under this Agreement after the Closing including, without
limitation, the obligations of each of the Transaction Companies under Article
VIII hereof; or (d) any claim by a third party relating to the use after the
Closing of the Trademark by Licensee (each as defined in the Trademark
Agreement), including, without limitation, product liability; provided, however,
that (a) there shall be no right of indemnification under this clause (d) in
respect to (i) claims by any of the Transaction Companies under this Agreement
or (ii) claims that the use of the Trademark (as defined in the Trademark
Agreement) after the Closing (as distinct from the use of a mark or component of
a mark not including TRW) infringes any third party's rights, and (b) the
Transaction Companies shall not have any liability under this clause (d) with
respect to any diminution in the value of shares of capital stock in Holdings.

        9.2.    Indemnification of Transaction Companies:  Subject to the
limitations set forth in Section 9.4 hereof, TRW hereby agrees and covenants
that after the Closing it will indemnify, defend and hold each of the
Transaction Companies and their subsidiaries harmless from and against any and
all liabilities, damages, losses, claims, costs and expenses (including, without
limitation, costs of collection and reasonable attorneys' fees) arising out of
or resulting from (a) either (i) any misrepresentation or breach of warranty by
TRW for which notice is given by such Transaction Company within the applicable
periods specified in Section 3.5 hereof or (ii) any claim by a person other than
the Transaction Companies and their subsidiaries, which claim is based upon one
or more allegations that, if true, would give rise to a right of indemnification
under clause (a)(i) of this sentence and for which notice is given by
Transaction Companies within
                                     -47-
<PAGE>
 
the applicable periods specified in Section 3.5 hereof; (b) any failure fully to
pay or satisfy or cause to be paid or satisfied any of the Excluded Liabilities
when due and payable; (c) nonperformance by any member of the TRW Group of any
obligation to be performed on the part of any member of the TRW Group under this
Agreement prior to the Closing and the nonperformance by TRW, Microwave or IS&S
International of any obligation to be performed on their respective parts after
the Closing, including, without limitation, the obligations of TRW under Article
VIII hereof; or (d) any claim that the use of the Trademark (as defined in the
Trademark Agreement after the Closing in accordance with the terms of the
Trademark Agreement infringes any trademark, service mark, trade name or other
proprietary right of any third party.  Any payments made by TRW pursuant to this
Article IX will be made to Operating Company.

        9.3.    Claims: If Section 6.4 hereof applies, the following provisions
of this Section 9.3 do not apply.  If an indemnified person (a "Claimant")
desires to make a claim under Section 9.1 or Section 9.2 hereof against an
indemnifying person (the "Indemnitor") which does not involve a claim by any
person other than the parties and their subsidiaries, then such Claimant will
make such claim by promptly delivering written notice to the other; provided,
however, that, subject to Section 3.5 hereof, the failure to give such notice
will not relieve any Indemnitor from any obligation hereunder except where, and
then solely to the extent that, such failure actually and materially prejudices
the rights of such Indemnitor.  If a Claimant desires to make a claim against an
Indemnitor under Section 9.1 or Section 9.2 hereof, as the case may be, which
involves a claim by a person other than the parties and their subsidiaries, then
such claim will be made in the following manner and be subject to the following
terms and conditions:

        (a)     Notice: The Claimant will give prompt written notice to the
                Indemnitor of any demand, claim or threat of litigation or the
                actual institution of any action, suit or proceeding
                (collectively, a "Claim") served on or instituted against the
                Claimant with respect to which the Claimant believes it would
                have a right of indemnification under Section 9.1 or Section 9.2
                hereof. In providing such notice, the Claimant will only state
                the existence of such Claim and need not admit or deny the
                validity of the facts or circumstances out of which such Claim
                arose. The failure to give such notice will not relieve an
                Indemnitor from any obligation hereunder except where, and then
                solely to the extent that, such failure actually and materially
                prejudices the rights of such Indemnitor.

        (b)     Responsibility for Defense: Within thirty (30) days after
                receipt of any such notice, but not less than five (5) working
                days prior to the time the Claimant is required to respond to a
                Claim, the Indemnitor may, by giving written notice to the
                Claimant, and provided that in such notice the Indemnitor also
                agrees that it has responsibility hereunder to indemnify the
                Claimant with respect to such Claim, assume responsibility for
                the defense of the Claim (thereby becoming the "Defending
                Party") in the name of the Claimant or otherwise as the
                Indemnitor may elect. The Claimant will assume responsibility
                for the defense of such Claim

                                     -48-
<PAGE>
 
                as the Defending Party if the Indemnitor does not elect to
                assume responsibility for the defense of such Claim as provided
                in the previous sentence, in which event the Indemnitor will
                reimburse the Claimant for the costs of defending against such
                Claim, including reasonable attorneys' fees and expenses, and
                will be responsible for any Losses (as defined in Section 9(c)
                hereof) the Claimant may suffer as a result of such Claim, if,
                but only to the extent that, the Claimant is in fact entitled to
                indemnification under this Agreement with respect to such Claim.
                Subject to the provisions of Sections 9.3(c) and 9.3(d) hereof,
                the Defending Party will have full authority to defend, cure,
                adjust, compromise or settle such Claim or appeal any judgment
                or ruling of a court or other tribunal in connection with such
                Claim in its own name and/or in the name of the other party.

        (c)     Right to Participate/Right to Assume Responsibility for Defense
                of a Claim: Notwithstanding a Defending Party's responsibility
                for the defense of a Claim, the other party will have the right
                to participate, at its own expense and with its own counsel, in
                the defense of a Claim and, upon receiving a written request
                from the other party, the Defending Party will consult with the
                other party from time to time on matters relating to the defense
                of such Claim and provide the other party with copies of all
                pleadings and material correspondence relating to such Claim. In
                the event that a Claim seeks equitable or injunctive relief, the
                Claimant may, at its option, and notwithstanding anything to the
                contrary in Section 9.3(b) hereof, assume responsibility for the
                defense of such portion of the Claim seeking equitable or
                injunctive relief. In the event that pursuant to the preceding
                sentence the Claimant has assumed responsibility for the defense
                of such portion of the Claim as seeks equitable or injunctive
                relief, the Indemnitor will reimburse Claimant for the costs of
                defending the Claim including reasonable attorneys' fees and
                expenses, and the Indemnitor will remain monetarily responsible
                for any and all liabilities, damages, losses, claims, costs and
                expenses (including, without limitation, costs of collection and
                reasonable attorneys' fees) (collectively "Losses") the Claimant
                may suffer as a result of such Claim, if, but only to the extent
                that, such defense costs and such Losses are otherwise subject
                to indemnification pursuant to this Agreement.

        (d)     Settlement: A Defending Party will provide the other party with
                timely written notice of any proposed adjustment, compromise or
                other settlement, including equitable or injunctive relief, of a
                Claim which the Defending Party intends to propose or accept, in
                which event the other party will within five business days after
                receipt thereof provide the Defending Party with a written
                notice (a "Response Notice") to the effect that (i) the other
                party consents to the settlement or (ii) the other party objects
                to the settlement, and in which event the following additional
                provisions will apply.

                                     -49-
<PAGE>
 
                (A)  In the event that the other party (i) consents to the
                settlement in a timely Response Notice, or (ii) fails to provide
                the Defending Party with a timely Response Notice, the Defending
                Party will have the right to propose or accept, as the case may
                be, such settlement and to enter into any agreement, in its own
                name and/or in the name of the other party, giving legal effect
                to all aspects of such settlement.

                (B)  When the Defending Party is also the Indemnitor, and the
                Claimant objects to the settlement by means of a timely Response
                Notice, then the Defending Party may, if it so elects, and
                provided that the settlement in question is purely monetary in
                nature and provides for a complete release of the Claim, tender
                the defense of the Claim to the Claimant by tendering the
                Claimant the amount of money proposed to be paid in settlement
                of the Claim (the "Tendered Amount"), in which case the
                Defending Party will have no further liability to the Claimant
                hereunder with respect to such Claim, and in which case the
                Claimant will have full responsibility for any and all defense
                costs and Losses thereafter resulting from such Claim (the
                "Claimant's Costs") and, in addition, once the Claimant's Costs
                have been fully and finally determined, will reimburse the
                Defending Party for the amount (if any) by which the Tendered
                Amount exceeds the Claimant's Costs.

                (C)  When the Defending Party is the Claimant, the Claim in
                question is not one that the Claimant assumed responsibility of
                pursuant to the second sentence of Section 9.3(c) hereof, and
                the Indemnitor objects to the settlement by means of a timely
                Response Notice, the Indemnitor will have the right to assume
                responsibility for the defense of the Claim by delivering with
                the Response Notice a notice in the form contemplated by the
                first sentence of Section 9.3(b) hereof. If the Indemnitor fails
                to exercise such right, and if the settlement in question would
                impose purely monetary obligations on the Indemnitor, the
                Defending Party will have the right to propose or accept, as the
                case may be, such settlement and to enter into any agreement, in
                its own name and/or in the name of the Indemnitor, giving legal
                effect to all aspects of such settlement, whereupon, if, but
                only to the extent that, the Defending Party is entitled to
                indemnification from the Indemnitor in respect to the Claim, and
                further subject to Sections 9.4 and 9.5 hereof, the amount paid
                under the terms of such settlement will be deemed to be Losses
                subject to indemnification to the extent, and only to the
                extent, such settlement is reasonable under all the facts and
                circumstances at the time of the settlement. Otherwise, Losses
                subject to indemnification will be deemed to be that portion of
                the amount paid under the terms of such settlement that would
                have been reasonable to pay under the terms of such settlement
                under all of the facts and circumstances at the time of such
                settlement.

                (D)  Except as provided in Section 9.3(d)(C) hereof, the
                Defending Party will have no authority to enter into any
                proposed settlement that the other party has
 
                                     -50-
<PAGE>
 
                objected to by means of a timely Response Notice. If the other
                party has acted unreasonably in objecting to a proposed
                settlement by means of a timely Response Notice, and the
                Defending Party did not have either the right to tender the
                defense of the Claim in question to the other party pursuant to
                Section 9.3(d)(B) hereof or the right to enter into the proposed
                settlement of the Claim pursuant to Section 9.3(d)(C) hereof,
                then the other party will indemnify the Defending Party against
                any and all Losses that the Defending Party may suffer as a
                result of such unreasonable objection.

        9.4.    Limitation on TRW Indemnification: Notwithstanding the
provisions of Section 9.2(a) hereof, TRW will be obligated to indemnify, defend,
and hold the Transaction Companies and their subsidiaries harmless from or
against any Losses arising out of a misrepresentation or breach of warranty by
TRW only if, and then to the extent, the aggregate amount of all timely claims
exceeds Five Million Dollars ($5,000,000). In no event will TRW's total
obligation to the Transaction Companies and their subsidiaries under Section
9.2(a) hereof exceed, in the aggregate, Fifty Million Dollars ($50,000,000). The
foregoing $5,000,000 and $50,000,000 limitations will not apply to claims based
upon (i) knowing, intentional conduct that constitutes common law fraud or (ii)
any misrepresentation or breach of warranty with respect to the following
representations: Section 3.2(n) (captioned "Taxes") and Section 3.2(k)
(captioned "Employee Benefits").

        9.5.    Limitation on Transaction Companies Indemnification:
Notwithstanding the provisions of Section 9.1(a) hereof, the Transaction
Companies will be obligated to indemnify, defend, and hold TRW and its
subsidiaries harmless from or against any Losses arising out of a
misrepresentation or breach of warranty by the Purchaser only if, and then to
the extent, the aggregate amount of all timely claims exceed Two Million Dollars
($2,000,000).  In no event will the Transaction Companies' total obligation to
TRW and its subsidiaries under Section 9.1(a) hereof exceed, in the aggregate,
Seventy Million Dollars ($70,000,000).

        9.6.    Miscellaneous:

        (a)     Certain Matters of Construction: References in this Article IX
                to representations or warranties set forth in a particular
                Section will be deemed to include without limitation (i) all
                representations and warranties in Parts specifically referred to
                in such Section and (ii) such representations and warranties as
                confirmed by the certificates referred to in Sections 5.1(a),
                5.1(k) and 5.2(a) hereof.

        (b)     Waiver of Subrogation: Each of the parties hereby waive any
                insurer's right of subrogation under this Agreement except
                solely to the extent such waiver would result in a limitation or
                termination of coverage under any policy.

        (c)     by either TRW or Purchaser if, through no fault of the party
                seeking termination, the Closing has not occurred on or prior to
                December 3, 1996.

        10.4.   Procedure and Effect of Termination: In the event of the
termination of this Agreement and the abandonment of the transactions
contemplated hereby pursuant to Section 10.3 hereof, written notice thereof will
forthwith be given by the party so terminating to the other party and this

abandoned, without further action. If this Agreement is terminated pursuant to
Section 10.3 hereof:

        (a)     each party will redeliver all documents, work papers and other
                materials of the other parties relating to the transactions
                contemplated hereby, whether so obtained before or after the
                execution hereof, to the party furnishing the same, and all
                confidential information received by any party hereto with
                respect to the other party will be treated in accordance with
                Section 11.2 hereof;

        (b)     all filings, applications and other submissions made pursuant
                hereto will, at the option of TRW or Purchaser and to the extent
                practicable, be withdrawn from the agency or other person to
                which made;
 
        (c)     there will be no liability or obligation hereunder on the part
                of TRW or Purchaser or any of their respective directors,
                officers, employees, affiliates, controlling 

                                     -52-
<PAGE>
 
                persons, agents or representatives, except that any liability or
                obligation of TRW or Purchaser (the "Responsible Party"), as the
                case may be, arising from a material breach by the Responsible
                Party of one or more of the provisions of this Agreement will
                survive such termination; and

          (d)   the obligations provided for in this Section 10.4 and the
                obligation to treat information in a confidential manner as set
                forth in Section 11.2 hereof will survive any such termination.

                                  ARTICLE XI

                                 Miscellaneous

          11.1.  Cooperation:  Each of the parties will cooperate with the other
parties, at the request and expense of the requesting party, in furnishing
information, testimony and other assistance in connection with any actions,
proceedings, arrangements and disputes with other persons or governmental
inquiries or investigations involving the conduct of the Business by the TRW
Group or the transactions contemplated hereby.

          11.2.  Confidentiality:  Reference is made to the Confidentiality
Agreement (the "Confidentiality Agreement") dated January 19, 1996 between
Purchaser and TRW.  Both parties will continue to be bound by and will continue
to abide by the terms and conditions of the Confidentiality Agreement.  TRW
agrees to cooperate with Purchaser, after the Closing, to obtain the return of
all documents and information supplied to other prospective purchasers of the
Business or part thereof pursuant to Confidentiality Agreements executed by such
prospective purchasers.  TRW will seek, and Purchaser agrees to accept,
assignments of Confidentiality Agreements that TRW entered into with other
prospective purchasers of the Business.

          11.3.  Severability:  If any provision of this Agreement will finally
be determined to be unlawful, then such provision will be deemed to be severed
from this Agreement and every other provision of this Agreement will remain in
full force and effect to the extent that such provisions can be given reasonable
effect in accordance with the intentions of the parties.

          11.4.  Expenses:  Except as otherwise provided in this Agreement, each
party will bear its own expenses incurred in connection with this Agreement and
the transactions contemplated hereby, whether or not such transactions will be
consummated.  For purposes of the preceding sentence, all expenses of TRW and
its subsidiaries (including, without limitation, expenses of the Business) in
connection with this transaction and the transactions contemplated hereby,
including, without limitation, all legal, accounting and other advisory costs
and expenses, broker's or finder's fees and expenses, investment banking fees
and expenses, corporate staff expenses and all retention or deal bonuses, if
any, will be paid by TRW and will not be charged by TRW to the Business;
provided, however, that the Business may pay or be charged for the salaries and
benefits

                                     -53-

(excluding retention or deal bonuses) of employees who are full time employees
of the Business or whose salaries and benefits are allocated to the Business in
the Ordinary Course of Business.

        11.5.   Bulk Sales: The parties waive compliance with the provisions of
any so-called bulk sales law of any state.

        11.6.   Notices:  All notices, requests and other communications

provided, however, that if either party will have designated a different address

        11.7.   Dispute Resolution: Except as provided in Section 2.8 hereof
concerning the Adjustment, if, after the Closing, the parties should have any
dispute among each other arising out of or relating to this Agreement or the
parties' respective rights and duties hereunder, then the parties will attempt
to resolve such dispute in the following manner:

                                     -54-
<PAGE>
 
        (a)     Notice: Either party may at any time deliver to the other a
                written dispute notice setting forth a brief description of the
                issue for which such notice initiates the dispute resolution
                mechanism contemplated by this Section 11.7.

        (b)     Negotiation: During the ninety (90) day period following the
                delivery of the notice described in Section 11.7(a) above,
                appropriate representatives of the parties will meet and seek to
                resolve the disputed issue through negotiation.

        (c)     Referral: If representatives of the parties are unable to
                resolve the disputed issue through negotiation within the first
                sixty (60) days of the period described in Section 11.7(b)
                hereof, the parties will refer the issue to an officer or
                executive officer of each party or a neutral person or persons
                satisfactory to both parties ("Referral Committee"). The
                procedures to be followed for presentation of each party's
                position with respect to the disputed issue and the method by
                which the Referral Committee will consider the issue and attempt
                to reach a decision will be determined by agreement of the
                parties at the time the matter is referred. Unless the parties
                have otherwise agreed in advance in writing, a decision of the
                Referral Committee pursuant to this Section 11.7 will not be
                binding upon the parties.

        (d)     Stay: No party will bring any action against another with
                respect to such dispute until expiration of such ninety (90) day
                period, unless the party bringing an action determines, based
                upon written advice of legal counsel, that an applicable statute
                of limitation may expire prior to the expiration of such ninety
                (90) day period. Nothing in this Section 11.7 will preclude any
                party from taking interim measures of protection in the form of
                seeking preliminary or temporary equitable relief.

        11.8.   Exclusive Remedy: The parties agree, to the fullest extent
permitted by law, that after the Closing none of them or any of their directors,
officers, employees, affiliates, controlling persons, agents, successors,
permitted assigns, or representatives will have any liability or responsibility
whatsoever to the other or such other's directors, officers, employees,
affiliates, controlling persons, agents, successors, permitted assigns, or
representatives' on any basis (including, without limitation, in contract or
tort, under federal or state securities laws or otherwise) based upon any
information provided or made available, or statements made, to Purchaser or the
members of the TRW Group or their respective directors, officers, employees,
affiliates, controlling persons, agents, successors, permitted assigns, or
representatives (or any omissions therefrom), including, without limitation,
information provided or statements made in the specific representations and
warranties set forth in this Agreement, except as and only to the extent
expressly set forth herein with respect to such representations and warranties,
covenants and rights to indemnification and subject to the limitations and
restrictions contained herein or to the extent any such liability or
responsibility is based upon a fraudulent representation or claim.

                                     -55-
<PAGE>
 
        11.9.   Assignment: This Agreement will be binding upon and inure to the
benefit of the successors of each of the parties hereto, but will not be
assignable by either party without the prior written consent of the other;
provided, however, that Purchaser may (i) assign its rights and delegate its
duties hereunder, in whole or in part, to Holdings pursuant to the Merger, (ii)
assign its rights and delegate its duties hereunder, in whole or in part, to one
or more of its subsidiaries, provided that Purchaser gives TRW prior written
notice of such assignment and unconditionally guarantees performance by
Purchaser's assignee, (iii) assign its rights hereunder, but subject to all
limitations contained hereunder including, without limitation, the provisions of
Article IX and Section 11.8 hereof, to one or more lenders of Operating Company
to secure obligations to such lender or lenders, or (iv) assign its rights and
delegate its duties hereunder, but subject to all limitations contained
hereunder including, without limitation, the provisions of Article IX and
Section 11.8 hereof, to the purchaser or purchasers of all or substantially all
of the Business (whether through a sale of assets or stock, merger or
otherwise).

        11.10   No Third Parties:  Neither this Agreement nor any provision set
forth herein is intended to, or will, create any rights in or confer any benefit
upon any person other than Lusk and the parties hereto and their successors and
permitted assigns.

        11.11.  Incorporation by Reference:  The Appendices to this Agreement
constitute integral parts of this Agreement and are hereby incorporated into
this Agreement by this reference.

        11.12.  Governing Law:  This Agreement will be governed by and construed
in accordance with the internal substantive laws of the State of New York,
except where the substantive laws of another jurisdiction mandatorily apply.

        11.13.  Counterparts: More than one counterpart of this Agreement may be
executed by the parties hereto, and each fully executed counterpart will be
deemed an original without production of the others.

        11.14.  Complete Agreement:  This sets forth the entire understanding of
the parties hereto with respect to the subject matter hereof and supersedes all
prior letters of intent, agreements, covenants, arrangements, communications,
representations or warranties, whether oral or written, by any officer, employee
or representative of either party relating thereto.

        11.15.  Consent to Jurisdiction:  Each of the parties agrees that all
actions, suits or proceedings arising out of or based upon this Agreement or the
Other Agreements or the subject matter hereof or thereof will be brought and
maintained exclusively in the United States District Court for the Southern
District of New York or the Supreme Court of the State of New York, county of
New York.  Each of the parties hereto by execution hereof (i) hereby irrevocably
submits to the United States District Court for the Southern District of New
York
                                     -56-
<PAGE>
 
or the Supreme Court of the State of New York, county of New York for the
purpose of any action, suit or proceeding arising out of or based upon this
Agreement or the Other Agreements or the subject matter hereof or thereof and
(ii) hereby waives, as a defense or otherwise, in any such action, suit or
proceeding, any claim that he or it is not subject personally to the
jurisdiction of the above-named courts, that he or it is immune from
extraterritorial injunctive relief or other injunctive relief, that his or its
property is exempt or immune from attachment or execution, that any such action,
suit or proceeding may not be brought or maintained in one of the above-named
courts, that any such action, suit or proceeding brought or maintained in one of
the above-named courts should be dismissed on grounds of forum non conveniens,
                                                         -----     ----------
should be transferred to any court other than one of the above-named courts,
should be stayed by virtue of the pendency of any other action, suit or
proceeding in any court other than one of the above-named courts, or that this
Agreement, the Other Agreements or the subject matter hereof or thereof may not
be enforced in or by any of the above-named courts.  Each of the parties hereto
hereby consents to service of process in any such suit, action or proceeding in
any manner permitted by the Federal Rules of Civil Procedure or the Civil
Practice Laws and Rules of New York, agrees that service of process by
registered or certified mail, return receipt requested, at the address specified
in or pursuant to Section 11.6 is reasonably calculated to give actual notice
and waives and agrees not to assert by way of motion, as a defense or otherwise,
in any such action, suit or proceeding any claim that service of process made in
accordance with Section 11.6 hereof does not constitute good and sufficient
service of process.  The provisions of this Section 11.15 will not restrict the
ability of any party to enforce in any court any judgment obtained in the United
States District Court for the Southern District of New York or the Supreme Court
of the State of New York, county of New York.

        11.16. Waiver of Jury Trial: To the extent not prohibited by applicable
law which cannot be waived, each of the parties hereto hereby waives, and
covenants that he or it will not assert (whether as plaintiff, defendant, or
otherwise), any right to trial by jury in any forum in respect of any issue,
claim, demand, cause of action, action, suit or proceeding arising out of or
based upon this Agreement, the Other Agreements or the subject matter hereof or
thereof, in each case whether now existing or hereafter arising and whether in
contract to tort or otherwise.  Any of the parties hereto may file an original
counterpart or a copy of this Section 11.15 with any court as written evidence
of the consent of each of the parties hereto to the waiver of his or its right
to trial by jury.

                                     -57-

            Noncompetition and Nonsolicitation; Permitted Activities
            --------------------------------------------------------

that during the Basic Covenant Term the TRW Group will not, for its own account 
or for the account of others, either as an owner, partner, joint venturer, 
shareholder, advisor, consultant or otherwise, participate in the promotion,

TRW Group from engaging in any of the Permitted Activities. Moreover the TRW
Group shall not, for a period of ten (10) years from date of Closing, directly
or indirectly, use, allow to be used, or license any third party to use, the
Trademark (as defined in the Trademark Agreement) in connection with a Competing
Business anywhere in the Covenant Territory. The provisions of the immediately
preceding sentence with respect to the Trademark shall survive termination of
this Agreement for any reason. Without limiting any right or remedy available
Licensee, Licensor acknowledges that breach by Licensor of the provisions of
this Section 8 would cause Licensee irreparable harm for which monetary damages
would be inadequate and that Licensee will be entitled to an injunction by any
court of competent jurisdiction to enjoin and restrain any violation or
threatened violation of this Section 8 by Licensor.

    2.2 Permitted Activities:  For purposes hereof, the term "Permitted 
Activities" includes the following:

         (a) Acquiring and holding an equity interest in any publicly-held
         corporation which has a Competing Business, provided that such interest
         does not provide, directly or indirectly, the power to direct or cause
         the direction of the management and policies of such corporation,
         whether through the ownership of voting securities, contract or
         otherwise, and provided further that such interest does not exceed five
         percent (5%) of the issued and outstanding voting securities of such
         corporation;

         (b) Acquiring and holding a controlling interest in any corporation,
         partnership or other business entity having a Competing Business (a) in
         the calendar year preceding such acquisition, the revenues of such
         Competing Business constituted not more than twenty percent (20%) of
         the total revenues of the acquired entity and (b) at the time of
         acquisition, the annual revenues of the Competing Business for the
         preceding fiscal year were less than U.S.$50,000,000, but only until
         such time as such annual revenues have exceeded that amount; and

         (c) Acquiring and holding a controlling interest in any corporation,
         partnership or other business entity having a Competing Business whose
         annual revenues exceeded U.S.$50,000,000 for the preceding fiscal year
         if the acquiring member of the TRW Group first, (a) for sixty (60) days
                                                  -----
         from the later of(x) the date of acquisition or (y) the date on which
         such Competing Business may no longer be held by such member of the TRW
         Group, negotiates in good faith with the Purchaser for the sale of
         Competing Business to the Purchaser Group on terms and conditions and
         at a price mutually agreeable to the parties, and second, (b) within
                                                           ------
         one hundred eighty (180) days after the end of such sixty (60) day
         period, either transfers the Competing Business to the Purchaser Group
         or, if the negotiations are unsuccessful, to a person or entity which
         is not a member of the TRW Group.

                                       3
<PAGE>
 
Notwithstanding the foregoing provisions of this Section 2.2, the term 
"Permitted Activities" does not include the acquisition or holding of an equity 
interest in any of the following corporations: Dun & Bradstreet; Equifax; Trans 
Union; Axciom; and First Data Corporation; provided, however, that so long as 
the equity securities of the corporation in question are publicly traded, the 
acquisition or holding of an equity interest in that corporation that does not 
exceed five percent (5%) of its issued and outstanding voting securities shall 
be permitted.

        2.3 Nonsolicitation: TRW hereby covenants to the Purchaser Group that
during the Covenant Term, each member of the TRW Group will not, directly or
indirectly, for its own account or for the account of others, either as an
owner, partner, shareholder, joint venturer, advisor, consultant or otherwise,
solicit or attempt to solicit any person or entity who is or has been a
customer, supplier, licensor, licensee or business relation of the Business
prior to or during the Covenant Term to cease its particular business
relationship with the Business.

        TRW further covenants to the Purchaser Group that during the Covenant 
Term, each member of the TRW Group will not, directly or indirectly, for its own
account or for the account of others, either as an owner, partner, shareholder,
joint venturer, advisor, consultant or otherwise, solicit or induce any person
or entity who is a director, officer, employee or agent of either the Business
or any member of the Purchaser Group to terminate his, her or its relationship
with, or employment by, either the Business or any member of the Purchaser
Group.

        2.4 Notice and Opportunity to Cure: If, during the Basic Covenant Term 
or the Trademark Covenant Term, Purchaser believes any member of the TRW Group 
has breached or intends to breach a covenant set forth in Section 2.1 or Section
2.3 hereof, then Purchaser will provide TRW with prompt written notice of such 
actual or anticipated breach and afford TRW a reasonable opportunity to prevent,
remedy, cure or defend against such breach, not to exceed sixty (60) days.

        2.5 Remedies: TRW hereby acknowledges and affirms that any breach of the
provisions of this Noncompetition Agreement may result in irreparable injury to
each member of the Purchaser Group and that a remedy at law alone may not be an
adequate remedy for such a breach, and that in addition to any other remedy it
may have but subject to the provisions of Section 2.4 hereof, each member of the
Purchaser Group shall be entitled to enforce the specific performance of this
Noncompetition Agreement and to obtain an immediate temporary injunction,
without having to post bond, to prevent any threatened or further violation for
this Noncompetition Agreement.

the foregoing, TWR agrees that the provisions of this Noncompetition Agreement

of prescribed activities or duration, then such geographical area, scope of

Noncompetition Agreement to the extent found by such court or arbitrator not to

number of recapitalization transactions Licensee has acquired the Business (as
defined in the Recapitalization Agreement); and

     WHEREAS, Licensor has been engaged for many years in developing and
marketing a broad range of products and services throughout the world including
information products and services of the Business, and is the owner of the TRW
name and the TRW trademark and service mark and logo associated therewith (such
TRW mark and logo and the use of the TRW mark as a prefix in a secondary mark
with another component used by the Business as of the Closing hereinafter
collectively referred to as the "Trademark") that identifies its various
businesses, products and services including those of the Business and symbolizes
the goodwill and reputation of the business connected therewith throughout the
world; and

     WHEREAS, Licensee recognizes the worldwide marketing value of Licensor's
good will and reputation as symbolized by the Trademark and is desirous of using
the Trademark in the Business that it is acquiring from Licensor and benefiting
from its goodwill and reputation in connection with Licensee's business
throughout the world; and

     WHEREAS, Licensee acknowledges that the reputation and goodwill as
symbolized by the TRW name and Trademark are of great value to Licensor and that
Licensor will suffer irreparable damage if Licensee engages in any activity or
course of conduct which threatens to diminish or negatively impact Licensor's
goodwill or reputation; and

     WHEREAS, the execution and delivery of this Agreement is a condition to
closing of the transactions contemplated by the Recapitalization Agreement; and

     WHEREAS, Licensor has imposed certain terms and conditions as to the use of
the Trademark which Licensee has accepted in order to protect Licensor's rights;
and
<PAGE>
 
     WHEREAS, the Parties wish to provide formal evidence of their Agreement.

     NOW, THEREFORE, for valuable consideration, the receipt of which is hereby
acknowledged, it is mutually agreed as follows:

     1.  Definitions.  Terms defined in the Recapitalization Agreement and not
otherwise defined herein are used herein as such terms are defined in the
Recapitalization Agreement.

     "Products and/or Services" shall mean the products and services sold or
provided by Licensee in the conduct of the Business following Closing that are
(i) the same as the products and services sold or provided by Licensor prior to
Closing, (ii) the same as the products and services of Licensor substantially
developed by Licensor as of the Closing, and (iii) with Licensor's prior written
approval, substantially similar to the products and services sold or provided
and/or substantially developed for sale by Licensor prior to Closing.

     2.  Subject Matter.  Subject to the terms and conditions hereinafter set
forth, Licensor hereby grants to Licensee the right to use the Trademark in
association with selling throughout the world the Products and/or Services.
Licensee shall, during the term of this Agreement, identify itself by stating

     4.  Limitations.  Notwithstanding anything in this Agreement, expressed or
implied, to the contrary:

    (a) Licensee may not use the Trademark as part of any corporate, business or
    trading name.

    (b) Licensee may not use the Trademark other than in connection with the
    Products and/or Services and as allowed under Section 2 hereof. With respect
    to any other products or services, Licensee shall use its own name and
    marks. However, resellers, affiliated bureaus, distributors and agents of
    the Business may, during the term hereof, continue to use the Trademark in
    connection with the Products and/or Services within the terms, conditions
    and limitations of their agreements with Licensor and resellers,

                                      -2-
<PAGE>
 
     affiliated bureaus, distributors and agents of the Business added following
     Closing may, during the term hereof, use the Trademark in connection with
     the Products and/or Services bearing the Trademark, provided they have
     executed agreements with substantially similar terms, conditions and
     limitations governing use of the Trademark and confirming that Licensor
     retains all right, title and interest to the Trademark.

     (c) Licensee may not assign its rights or obligations under this Agreement
     to any other person without the express prior written approval of Licensor,
     which Licensor may withhold in its sole discretion, provided, however, that
     Licensor will cooperate with Licensee in granting written licenses by
     Licensor to use the Trademark to such legal entities related to or
     succeeding Licensee in connection with the Business as Licensee may select,
     provided any such entities expressly undertake in writing to be bound by
     terms, conditions and limitations substantially identical to those of this
     Agreement. Licensor, however, shall have the right to assign this Agreement
     and its rights hereunder.

     (d) Any and all use of the Trademark by Licensee shall inure to the benefit
     of Licensor and Licensee acknowledges that Licensor owns all right, title
     and interest to the Trademark and, except as set forth in this Agreement,
     reserves all rights thereto, specifically including, without limitation,
     all rights to license or authorize use of the Trademark.

     (e) Following the Closing, Licensee shall be permitted to utilize in the
     conduct of the Business all inventories, existing as of the Closing, of
     marketing collateral, including brochures, product and service
     descriptions, catalogs and similar material, manuals, instruction
     materials, packaging and other printed material with or without modifying
     the same, provided that Licensee uses reasonable efforts to advise the
     users and/or recipients that the new source of such Products and Services
     is Licensee and not Licensor.

     5.  Fees.  Upon execution of this Agreement, Licensee shall pay to TRW, by
wire transfer in immediately available funds to the account previously specified
in writing by TRW, the sum of Twenty-Six Million Dollars ($26M) as a lump sum
paid-up by royalty for the use of the Trademark in connection with the Products
and/or Services during the term of this Agreement.

     6.  Quality Control.  In order to assure the quality and nature of the
Products and/or Services bearing the Trademark and protect the reputation of
Licensor:

     (a) Licensor acknowledges that the quality standards, specifications, and
     related policies, procedures and processes for products and/or services
     bearing the Trademark as of the Closing (the "Standards") are deemed
     acceptable to Licensor and Licensee

                                      -3-
<PAGE>
 
     agrees to continue to maintain the quality of the Products and/or Services
     bearing the Trademark consistent with Licensor's Standards in effect prior
     to Closing.

     (b) On or before the twentieth day of each calendar quarter during the term
     of this Agreement, Licensee shall make available for Licensor's review
     copies of all material complaints, claims, suggestions and regulatory or
     judicial inquiries, requests, recommendations, actions or orders
     ("Comments") as to the Products and/or Services bearing the Trademark as
     embodied in any medium of tangible expression from third parties received
     by Licensee at its principal offices, and all correspondence from or to
     such third party concerning any Comments received during the preceding
     quarter.

     (c) Licensor shall have the right to enter Licensee's premises, upon
     reasonable prior notice during regular business hours, and have the right
     to inspect and examine the Products and/or Services bearing the Trademark
     and to review all records of Licensee relating to the quality of the
     Products and/or Services bearing the Trademark. Licensor shall be able to
     exercise such right, as a minimum, every four months and in any case where
     an event may arise that, in its reasonable good faith judgment, requires
     such on-site review. Licensor shall conduct such activities in a manner not
     to interfere with Licensee's business operations.

     (d) In the event that any Products and/or Services bearing the Trademark
     are found by Licensor or its designee not to meet the Standards, Licensor
     shall so notify Licensee in writing. Licensor shall specify to Licensee in
     reasonable detail the respects in which the Standards are not being met
     and, unless Licensee, within ninety (90) days of its receipt of such
     notice, takes corrective measures which reasonably rectify the deficiency,
     Licensee's right to use the Trademark shall immediately terminate upon
     notice to that effect from Licensor and this Agreement shall thereupon
     terminate.

     7.  Intellectual Property Control.  (i) Licensee undertakes to use
reasonable efforts to cooperate with Licensor, at Licensor's expense, in
protecting the Trademark.  In furtherance of such purposes Licensee shall:

     (a) Use the Trademark only in accordance with the terms of this Agreement;

     (b) At Licensor's request, affix appropriate trademark and service mark
     notations (e.g. "TM" or "(R)") and wording and otherwise make proper use of
     the Trademark by using it as a proprietary trademark and/or service mark
     and indicating that the Trademark is owned by Licensor and used by Licensee
     with Licensor's permission, on all promotional and advertising materials
     and Products and/or Services;

     (c) Not use any name, mark, device, symbol, insignia, designation, labeling
     or packaging in connection with the Trademark, other than such of the
     foregoing as Licensee may from time to time use in the ordinary course of
     Licensee's conduct of the

                                      -4-
<PAGE>
 
     Business, without the prior written approval of Licensor, and not apply to
     register the Trademark in any manner anywhere in the world, with or without
     a secondary component;

     (d) Comply with all applicable laws and regulations with respect to the
     production, distribution and sale of the Products and Services; and

     (e) Execute documents and take such reasonable actions as may be required
     by Licensor in connection with the protection of the Trademark and the
     registrations thereof, including, without limitation, cooperate with
     Licensor in executing and filing Registered User Agreements as necessary or
     desirable, and in applying to register and renew registrations of the
     Trademark in such classes and countries as Licensor may wish to do so in
     its sole discretion.

     (ii) Each of Licensee and Licensor shall promptly provide the other written
     notice in the event either party becomes aware of any actual or threatened
     use of the Trademark in connection with a Competing Business (as defined in
     the Non-Competition Agreement) by any third party. In such event, Licensor
     shall have the first right at its own expense to take such action,
     including the initiation of legal proceedings, to prevent and terminate
     such use. If within ninety (90) days, Licensor elects not to pursue any
     action, Licensee shall then have the right, at its own expense, to take
     such action, including the initiation of legal proceedings, to prevent and
     terminate such use. The party conducting such action shall control its
     conduct and the other party shall cooperate in any such proceeding, such
     cooperation to include, without limitation, the joining of the other party
     as a party to the action when either party is required by law to join the
     other party to such an action in order to bring the action. Any recovery in
     any such action or proceeding shall first be paid to reimburse the parties
     for their respective out-of-pocket expenses associated with such action or
     proceeding (such amounts to be paid on a pro rata basis in the event any
     recovery is less than the total of the parties' out-of-pocket expenses) and
     any remaining recovery shall be paid to Licensee.

     (ii) Licensor shall, at its own expense, file all applications, affidavits
     and other documents necessary to maintain the effective registration of the
     Trademark in the United States Patent and Trademark Office and in each
     other country in which the Trademark is registered in connection with the
     Business on the date of Closing but Licensor and/or Licensee shall not
     apply to register any marks that include the Trademark in connection with
     the Business.

     8.  Termination.  Notwithstanding anything to the contrary, this Agreement
shall automatically terminate upon notice by Licensor to Licensee upon the
occurrence of any of the following events:
                                     
                                      -5-

     (a) Breach by Licensee of any material term or condition of this Agreement,
     which breach is not cured within ninety (90) days after Licensee's receipt
     of written notice setting forth the particular breach. It is expressly
     understood that breach of the Standards shall be governed by the provisions
     of Section 5(d).

     (b) Any assignment of Licensee's assets or business for the benefit of
     creditors, or appointment of a trustee or receiver, or like official to
     administer or conduct the business of Licensee or adjudication in any legal
     proceeding that Licensee is either insolvent or otherwise unable to meet
     its financial obligations as they become due or is a voluntary or
     involuntary bankrupt.

     (c) Licensee or all or substantially all of its operations or assets are
     confiscated, nationalized or expropriated or in any other manner
     controlled, either directly or indirectly, by any government, national,
     state or municipal, or any agency thereof.

     (d) Licensee engages in any course of conduct or activities which generate
     materially negative national publicity asserting that Licensee's business
     practices do not conform to applicable law or standard industry practices
     and the TRW name, mark and/or logo is referenced in a negative manner in
     two or more print or television or radio media with national circulation or
     exposure over the course of any week or is the subject of significant use
     on the Internet over the course of any week and which negative publicity is
     not responded to by Licensee in a reasonable period after Licensee receives
     notice of such from Licensor with Licensee's press releases and written
     responses directly to the media outlets creating such publicity, and if

     1.2.   Defense of Actions.  If an Indemnified Party desires to make a claim
            ------------------                                                  
against the Indemnifying Parties under Section 1.1 hereof, then such claim will
be made in the following manner and be subject to the following terms and
conditions:

     a.     Notice: The Indemnified Party will give prompt written notice to the
            Indemnifying Parties of any demand, claim or threat of litigation or
            the actual institution of any action, suit or proceeding
            (collectively, a "Claim") served on or instituted against the
                              -----                                      
            Indemnified Party with respect to which the Indemnified Party
            believes it would have a right of indemnification under Section 1.1
            hereof. In providing such notice, the Indemnified Party will only
            state the existence of such Claim and need not admit or deny the
            validity of the facts or circumstances out of which such Claim
            arose. The failure to give such notice will not relieve the
            Indemnifying Parties from any obligation hereunder except where, and
            then solely to the extent that, such failure actually and materially
            prejudices the rights of the Indemnifying Parties.

     b.     Responsibility for Defense: Within thirty (30) days after receipt of
            any such notice, but not less than five (5) working days prior to
            the time the Indemnified Party is required to respond to a Claim,
            the Indemnifying Parties shall, by giving written notice to the
            Indemnified Party, assume responsibility for the defense of the
            Claim (thereby becoming the "Defending Party") in the name of the
                                         ---------------                     
            Indemnified Party; provided, however, that the Indemnifying Parties
            and the Indemnified Party may agree at such time or at any time
            thereafter that the Indemnified Party will assume defense of such
            Claim (thereby becoming the "Defending Party") in which event the
                                         ---------------                     
            Indemnifying Parties will reimburse the Indemnified Party for the
            costs of defending against such Claim, including reasonable
            attorneys' fees and expenses, and will be responsible for any Losses
            the Indemnified Party may suffer as a result of such Claim, if, but
            only to the extent that, the Indemnified Party is in fact entitled
            to indemnification under this Agreement with respect to such Claim.
            Subject to the provisions of Sections 1.2(c), 1.2(d), 1.2(e) and
            1.2(f) hereof, the Defending Party will have full authority to
            defend, cure, adjust, compromise or settle such Claim or appeal any
            judgment or ruling of a court or other tribunal in connection with
            such Claim in its own name and/or in the name of the other party.
            The parties who are not the Defending Party shall reasonably
            cooperate in the defense of any action for which an Indemnified
            Party seeks indemnification under this Agreement.

     c.     Right to for Participate: Notwithstanding a Defending Party's
            responsibility for the defense of a Claim, the other party will have
            the right to participate, at its own expense and with its own
            counsel, in the defense of a Claim and, upon receiving a written
            request from the other party, the Defending Party will consult with
            the other party from time to time on matters relating to the defense
<PAGE>
 
            of such Claim and provide the other party with copies of all
            pleadings and material correspondence relating to such Claim.

     d.     Equitable or Injunctive Relief: In the event that a Claim seeks
            equitable or injunctive relief, the Indemnified Party may, at its
            option, and notwithstanding anything to the contrary in Section
            1.2(b) hereof, assume responsibility for the defense of such portion
            of the Claim seeking equitable or injunctive relief. In the event
            that pursuant to the preceding sentence the Indemnified Party has
            assumed responsibility for the defense of such portion of the Claim
            as seeks equitable or injunctive relief, the Indemnifying Parties
            will reimburse the Indemnified Party for the costs of defending the
            Claim including reasonable attorneys' fees and expenses, and the
            Indemnifying Parties will remain monetarily responsible for any and
            all Losses the Indemnified Party may suffer as a result of such
            Claim, if, but only to the extent that, such defense costs and such
            Losses are otherwise subject to indemnification pursuant to this 
            Agreement.

     e.     Financial Difficulty: In the event that any of the Indemnifying
            Parties is subject to Financial Difficulty (as defined below), the
            Indemnified Party may, at its option, and notwithstanding anything
            to the contrary in Section 1.2(b) hereof, assume responsibility for
            the defense of any Claim then pending. In the event that pursuant to
            the preceding sentence the Indemnified Party has assumed
            responsibility for the defense of such Claim, the Indemnifying
            Parties will reimburse the Indemnified Party for the costs of
            defending the Claim including reasonable attorneys' fees and
            expenses, and the Indemnifying Parties will remain monetarily
            responsible for any and all Losses the Indemnified Party may suffer
            as a result of such Claim, if, but only to the extent that, such
            defense costs and such Losses are otherwise subject to
            indemnification pursuant to this Agreement. "Financial Difficulty"
                                                         -------------------- 
            shall mean:

               (1)  that there shall have occurred and be continuing any of the
               following events under the governing instrument or agreement
               relating to any Indemnifying Party's indebtedness for borrowed
               money which has an unpaid principal amount in excess of
               $25,000,000 ("Debt"):  (A) such Indemnifying Party shall have
                             ----                                           
               failed to pay when due the principal of, or interest on, the Debt
               and such failure shall not have been cured, waived or otherwise
               remedied within thirty (30) days of such failure, (B) the
               holder(s) of any Indemnifying Party's Debt shall have accelerated
               the payment of the entire principal amount thereof, or (C) such
               Indemnifying Party shall have failed to comply with the financial
               covenants set forth in any such governing instrument or agreement
               and such failure shall not have been cured, waived or otherwise
               remedied within sixty (60) days of such failure;
<PAGE>
 
               (2)  that such Indemnifying Party shall have commenced or become
               subject to a case under Title 11 of the United States Code or
               shall be adjudged or found by a court of competent jurisdiction
               to be bankrupt or insolvent; or

               (3)  there shall have occurred the sale of all or substantially
               all of the assets of the Indemnifying Parties.

          During the pendency of any Claim, the Indemnifying Parties will
          promptly provide the Indemnified Parties with a copy of any notice
          sent to or received from the holder of any Debt to the effect that any
          event constituting a Financial Difficulty has occurred.

     f.   Settlement:  A Defending Party will provide the other party with
          timely written notice of any proposed adjustment, compromise or other
          settlement, including equitable or injunctive relief, of a Claim which
          the Defending Party intends to propose or accept, in which event the
          other party will within five (5) business days after receipt thereof
          provide the Defending Party with a written notice (a "Response
                                                                --------
          Notice") to the effect that (i) the other party consents to the
          settlement or (ii) the other party objects to the settlement, and in
          which event the following additional provisions will apply:

               (1)  In the event that the other party (i) consents to the
               settlement in a timely Response Notice, or (ii) fails to provide
               the Defending Party with a timely Response Notice, the Defending
               Party will have the right to propose or accept, as the case may
               be, such settlement and to enter into any agreement, in its own
               name and/or in the name of the other party, giving legal effect
               to all aspects of such settlement.

               (2)  When the Defending Party is also an Indemnifying Party, and
               the Indemnified Party objects to the settlement by means of a
               timely Response Notice, then the Defending Party may, if it so
               elects, and provided that the settlement in question is purely
               monetary in nature and provides for a complete release of the
               Claim, tender the defense of the Claim to the Indemnified Party
               by tendering the Indemnified Party the amount of money proposed
               to be paid in settlement of the Claim (the "Tendered Amount"), in
                                                           ---------------      
               which case the Defending Party will have no further liability to
               the Indemnified Party hereunder with respect to such Claim, and
               in which case the Indemnified Party will have full responsibility
               for any and all defense costs and Losses thereafter resulting
               from such Claim (the "Indemnified Party's Costs") and, in
                                     -------------------------          
               addition, once the Indemnified Party's Costs have been fully and
               finally 
<PAGE>
 
               determined, will reimburse the Defending Party for the amount (if
               any) by which the Tendered Amount exceeds the Indemnified Party's
               Costs.

               (3)  When the Defending Party is the Indemnified Party, the Claim
               in question is not one that the Indemnified Party assumed
               responsibility of pursuant to Section 1.2(d) or 1.2(e) hereof,
               and the Indemnifying Parties object to the settlement by means of
               a timely Response Notice, the Indemnifying Parties will have the
               right to assume responsibility for the defense of the Claim by
               delivering with the Response Notice a notice in the form
               contemplated by the first sentence of Section 1.2(b) hereof.  If
               the Indemnifying Parties fail to exercise such right, and if the
               settlement in question would impose purely monetary obligations
               on the Indemnifying Parties, the Defending Party will have the
               right to propose or accept, as the case may be, such settlement
               and to enter into any agreement, in its own name and/or in the
               name of the Indemnifying Parties, giving legal effect to all
               aspects of such settlement, whereupon, if, but only to the extent
               that, the Defending Party is entitled to indemnification from the
               Indemnifying Parties in respect to the Claim, the amount paid
               under the terms of such settlement will be deemed to be Losses
               subject to indemnification to the extent, and only to the extent,
               such settlement is reasonable under all the facts and
               circumstances at the time of the settlement.  Otherwise, Losses
               subject to indemnification will be deemed to be that portion of
               the amount paid under the terms of such settlement that would
               have been reasonable to pay under the terms of such settlement
               under all of the facts and circumstances at the time of such
               settlement.

               (4)  Except as provided in Section 1.2(f)(3) hereof, the
               Defending Party will have no authority to enter into any proposed
               settlement that the other party has objected to by means of a
               timely Response Notice.  If the other party has acted
               unreasonably in objecting to a proposed settlement by means of a
               timely Response Notice, and the Defending Party did not have
               either the right to tender the defense of the Claim in question
               to the other party pursuant to Section 1.2(f)(2) hereof or the
               right to enter into the proposed settlement of the Claim pursuant
               to Section 1.2(f)(3) hereof, then the other party will indemnify
               the Defending Party against any and all Losses that the Defending
               Party may suffer as a result of such unreasonable objection.

          1.  Demise of Premises; Purchase Option.
              ----------------------------------- 

          (a) In consideration of the rents and covenants herein stipulated to
be paid and performed, Landlord hereby demises, and lets to Tenant, and Tenant
hereby lets from Landlord, for the terms herein described, the premises (herein
called the "Premises") consisting of (i) the land described in Exhibit A
                                                               ---------
attached hereto and made a part hereof (herein called the "Land Parcel"); (ii)
all buildings, structures and other improvements constructed and to be
constructed thereon (including all building equipment and fixtures, if any,
owned by Landlord, but excluding trade equipment and fixtures owned by Tenant)
(herein called the "Improvements"); (iii) all the personal property as described
in Exhibit A-1 attached hereto and made a part hereof; and (iv) all easements,
   -----------                                                                
rights and appurtenances relating thereto, all upon the terms and conditions
herein specified.  Landlord shall have the right, after the date of this Lease
and at any time, to sell, convey, encumber or transfer the Premises, subject to
the rights of Tenant under this Lease.

          (b) After the expiration of the Primary Term (as hereinafter defined
in Section 4), Tenant shall have the option, and Landlord hereby grants to
Tenant the option, to purchase the Premises at the then fair market value of the
Premises, which fair market value shall be determined prior to the end of the
Primary Term as provided in Attachment 3 attached hereto and made a part hereof.
                            ------------                                        

          2.  Title and Condition.  The Premises are demised and let in their
              -------------------                                            
present condition and without warranty or representation by Landlord, and
subject to (a) the rights of any parties in possession, (b) the state of the
title thereto existing at the time Landlord acquired title to the Premises and
as of the commencement of the Term (as hereinafter defined in Section 4) of this
Lease, (c) any state of facts which an accurate survey or physical inspection
thereof might show, (d) all private deed restrictions and protective covenants,
and all applicable laws, rules, regulations, ordinances and restrictions now in
effect or hereafter adopted by any governmental authority, including, without
limitation, all zoning regulations, restrictions, rules and ordinances, building
restrictions and other laws and regulations, (e) any violations of such
restrictions, covenants, laws, rules, regulations or ordinances which may exist

construction currently in progress and commenced prior to the date of this
Lease, and any liens, inchoate or choate, unperfected or perfected, previously,
currently or in the future arising therefrom.  Tenant represents that it
<PAGE>
 
has examined the title to and the condition of the Premises and has found the
same to be satisfactory to it.  Tenant acknowledges and confirms that Tenant is
fully familiar with the physical condition of the Premises and that Landlord
makes no representation or warranty, expressed or implied, with respect to same
or with respect to the location, use, description, design, merchantability,
fitness for use for particular purpose, condition or durability thereof, or as
to quality of the material or workmanship therein, or as to Landlord's title
thereto or ownership thereof, or otherwise; and all risks incidental to the
Premises shall be borne by Tenant to the extent of matters that arise during the
Term of this Lease.  Landlord leases and Tenant accepts the Premises as is, with
all faults and in the event of any defect or deficiency of any nature in the
Premises or any fixture or other item constituting a portion of Premises,
whether patent or latent, neither Landlord nor Permitted Beneficiary shall have
any responsibility or liability with respect thereto.  THE PROVISIONS OF THIS
SECTION HAVE BEEN NEGOTIATED AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND
NEGATION BY LANDLORD OF, AND LANDLORD DOES HEREBY DISCLAIM ANY AND ALL
WARRANTIES BY LANDLORD, EXPRESS OR IMPLIED, WITH RESPECT TO THE PREMISES OR ANY
FIXTURE OR OTHER ITEM CONSTITUTING A PORTION OF THE PREMISES, WHETHER ARISING
PURSUANT TO THE UNIFORM COMMERCIAL CODE OR OTHER LAW, NOW OR HEREAFTER IN
EFFECT, OR OTHERWISE.

          3.   Use of Premises.
               --------------- 

          (a)  Tenant and any permitted sublessee or assignee may use the
Premises for any lawful purpose, provided that, in Landlord's reasonable
judgment, such use (i) creates no detrimental environmental effects or increased
environmental risks to the Promises or to other property and does not result in
any increased risk of liability to Landlord, (ii) creates or requires no
modifications to the physical structure of any portion of the Premises except in
accordance with the provisions of Section 11 of this Lease, unless all such
modifications are approved in advance and in writing by Landlord and Permitted
Beneficiary as provided herein, (iii) creates no adverse tax consequences for
Landlord, (iv) will not lessen the fair market value of the Premises to an
amount which is below its fair market value immediately prior to the
commencement of such use, (v) does not change the primary character of the
Premises, and (vi) does not violate any other provisions of this Lease or any
term of any other agreement or restriction to which the Premises are subject, or
cause the Premises to be in violation of any laws, ordinances, rules,
regulations, covenants, or requirements applicable thereto.  The restrictions
set forth in (i) through (vi) inclusive in this subsection (a) are hereinafter
collectively referred to as the "Use Restrictions."  Tenant and any permitted
sublessee or assignee shall not create or suffer to exist any public or private
nuisance, hazardous or illegal condition or waste on or with respect to the
Premises.

          (b)  Tenant shall not conduct its business operation in the Premises
unless and until (and only during such time as) all necessary certificates of
occupancy, permits, licenses and

                                      -2-
<PAGE>
 
consents from any and all appropriate governmental authorities have been
obtained by Tenant and are in full force and effect.

          4.   Terms.  Subject to the terms and conditions hereof, Tenant shall
               -----                                                           
have and hold the Premises for a primary term (herein called the "Primary Term")
commencing on April 15, 1993, and continuing through October 15, 2010.
Thereafter, Tenant shall have the right and option to extend this Lease for four
(4) consecutive terms of five (5) years each (herein collectively and
individually called an "Extended Term," and together with the Primary Term,
called the "Term") unless this Lease shall be sooner terminated pursuant to the
terms hereof. Each Extended Term shall commence on the day immediately
succeeding the expiration date of the Primary Term or the preceding Extended
Term.  This Lease shall not be extended for an Extended Term and Tenant shall be
deemed not to have exercised its option to extend, unless (a) Tenant has given
written notice to Landlord at least two (2) years prior to the end of the then
Term of this Lease of Tenant's intention to so extend this Lease, and (b) at the
time at which any such extension would otherwise take effect, no default or
Event of Default exists under this Lease.  If Tenant does not timely and
properly give such notice of Tenant's intention to so extend this Lease, Tenant
shall have no further option or obligation to extend this Lease.  Further, if
Tenant does not timely and properly notify Landlord of Tenant's intention to
extend this Lease, or if any default or any Event of Default exists and is
continuing at such time under this Lease, then Landlord shall have the right
during the remainder of the Term of this Lease to advertise the availability of
the Premises for sale or reletting and to erect upon the Premises signs
appropriate for the purpose of indicating such availability; provided, that such
signs do not unreasonably interfere with the use of the Premises by Tenant.

          5.   Rent and Termination Values.
               --------------------------- 

          (a)  Tenant covenants to pay directly to Permitted Beneficiary (as
hereinafter defined) as installments of rent to Landlord for the Premises during
the Term of this Lease, the amounts determined pursuant to Exhibit B hereto,
                                                           ---------        
subject to adjustment as provided in Section 5(c) below (herein called the
"Basic Rent") on the dates set forth in said Exhibit B (herein called the "Basic
                                             ---------                          
Rent Payment Dates") in arrears.  Basic Rent payments shall be allocated to
Tenant's use of the Premises during the Lease period in which the Basic Rent
Payment Date for such Basic Rent payment falls.  Tenant covenants to pay the
Basic Rent by wire transfer of immediately available funds to Permitted
Beneficiary at Norwest Bank Iowa, N. A., Seventh and Walnut Streets, Des Moines,
Iowa 50309, for credit to Principal Mutual Life Insurance Company, General
Account No. 014752 Re: D-399815 and/or to such other person or such other place
or account as Landlord and Permitted Beneficiary, if any, from time to time may
designate to Tenant in writing.

          (b)  Tenant covenants that all other amounts, liabilities and
obligations which Tenant assumes or agrees to pay or discharge pursuant to this
Lease, together with every fine, penalty, interest and cost which may be added
for nonpayment or late payment thereof, shall

                                      -3-
<PAGE>
 
constitute additional rent hereunder (herein called "Additional Rent").  In the
event of any failure by Tenant to pay or discharge any of the foregoing,
Landlord shall have all rights, powers and remedies provided herein or by law in
the case of nonpayment of Basic Rent. Tenant also covenants to pay to Landlord
on demand an amount equal to four percent (4%) of the payment amount then due,
on all overdue installments of Basic Rent or Additional Rent not paid within any
applicable grace period.  In addition, Tenant further covenants to pay to
Landlord on demand, after the expiration of five (5) days after notice from
Landlord of payment by Landlord on behalf of Tenant of any of Tenant's
obligations under this Lease, interest on all such obligations paid by Landlord
and not reimbursed by Tenant, at the rate of the lesser of (i) fifteen percent
(15%) per annum, or (ii) the maximum rate not prohibited by applicable law,
which interest shall accrue from and after the fifth day after such notice from
Landlord, and shall continue to accrue until Landlord is repaid in full for such
payment made on behalf of Tenant.  Notwithstanding anything in this Lease to the
contrary, with respect to any portion of Additional Rent comprised solely of
late charges and/or default rate interest, any failure of Tenant to pay any such
amounts shall not constitute an Event of Default under this Lease until the
expiration of five (5) days after notice from Landlord that such amounts have
become due and payable, specifying the nature and amount of such late charges
and/or default rate interest.

          (c)  The calculation of Basic Rent and the calculation of the amount
to be paid to Landlord by Tenant in the event of certain occurrences as
expressly provided in this Lease wherein the term "Termination Value" is used
(the amounts set forth on Exhibit D attached hereto and made a part hereof, as
                          ---------
may be adjusted from time to time pursuant to the provisions of this subsection
being referred to in this Lease as the "Termination Value") initially payable
pursuant to this Lease have been based on the assumptions described on 
Exhibit C. The Basic Rent and the Termination Value have been calculated to 
- ---------      
provide Landlord with a certain after-tax rate of return, total after-tax return
per dollar of equity invested and present value of after-tax lease income [as
booked under FAS 13 (defined in Section 32), per dollar of equity invested]
(hereinafter collectively called "Lessor's Anticipated Economics"). Subject to
the provisions of (i), (ii), (iii), (iv) and (v) of this subsection 5(c) and the
provisions of subsection 5(d), if either Landlord or Tenant determines at any
time (within the notice period provided below in this Section 5(c)) that any of
such assumptions are inaccurate or are not as set forth on Exhibit C, whether
                                                           ---------         
due to being inaccurate when made or due to any changes in facts or
circumstances (an "Inaccurate Assumption"), then the Basic Rent and the
Termination Value shall be appropriately adjusted, as provided below, from and
effective as of the date that such Inaccurate Assumption first became
inaccurate, by such amounts as shall preserve Lessor's Anticipated Economics
(such adjustments being hereinafter called, respectively, the "Rent Adjustments"
and the "Termination Value Adjustments" and collectively "Rent/Termination Value
Adjustments"). Notwithstanding anything in this Section 5 to the contrary but
only in connection with the procedure for effecting Rent/Termination Value
Adjustments pursuant to this Section 5(c), (i) the amount of Basic Rent and the
Termination Value must be in amounts which, in all respects, continue to comply
with all relevant Code (as defined in Exhibit C hereto) provisions, and all
                                      ---------                            
regulations, published rulings, procedures and announcements

pertaining thereto, (ii) Landlord shall be entitled to require that all
provisions of the Code, and regulations, published rulings, procedures and/or
announcements pertaining thereto shall be taken into account in making any
calculation of any Rent/Termination Value Adjustment, (iii) a Rent/Termination
Value Adjustment which results from a Federal Tax Law Change (as defined in
Exhibit C) and which would, absent this restriction, result in an increase in
the Basic Rent or Termination Value shall not be made if the result of such
adjustment would cause (in the opinion of tax counsel for Landlord) the failure
of the Lease to qualify as a true lease for federal income tax purposes unless
the Landlord in its sole discretion elects to waive this restriction, (iv) a
Rent/Termination Value Adjustment which results from a Federal Tax Law Change
and which would, absent this restriction, result in a decrease in the Basic Rent
or Termination Value shall not be made if the result of such adjustment would
cause (in the opinion of tax counsel for Landlord) the failure of the Lease to
qualify as a true lease for federal income tax purposes, and (v) the Basic Rent
shall in no event be adjusted to an amount which is less than the regularly
scheduled debt service payments due to any Permitted Beneficiary (the "Debt
Service Amounts"). The procedure for effecting Rent Adjustments and Termination
Value Adjustments shall be as provided below. Either party may submit any
proposed Rent/Termination Value Adjustment calculated in accordance with the
provisions of this Section 5(c), along with the basis for such Rent/Termination
Value Adjustment, to the other party, and if the other party does not object to
such proposed Rent/Termination Value Adjustment in writing within twenty (20)
days following such submission, setting forth in specific detail the basis for
its objection, the Basic Rent and Termination Value shall be deemed adjusted in
accordance with such proposed Rent/Termination Value Adjustment without the
necessity of any further action or documentation by any party; provided,
however, Tenant shall not be allowed to submit any proposed Rent/Termination
Value Adjustment unless it has first given Landlord written notice that it
intends to make such submission and Landlord fails to make a proposed
Rent/Termination Value Adjustment within thirty (30) days of such notice. If the
other party objects to the proposed Rent/Termination Value Adjustment in writing
and in detail within said twenty (20) day period, Landlord and Tenant shall use
their best efforts to reach agreement as to any such proposed Rent/Termination
Value Adjustment. If agreement is reached, the Basic Rent and Termination Values
shall be adjusted in accordance with such agreement when reduced to writing. If
Landlord and Tenant are unable to reach a written agreement within thirty (30)
days of the submitting party's receipt of the other party's written objection,
then Ernst & Young or such other nationally recognized accounting firm as agreed
upon by Landlord and Tenant (the "Third Party Accounting Firm") shall be engaged
to review the proposed Rent/Termination Value Adjustment and shall make a
determination as to the resolution of the proposed Rent/Termination Value
Adjustment so as to cause such Rent/Termination Value Adjustment to be properly
made in accordance with the provisions of this Lease. The determination of the
Third Party Accounting Firm made in accordance with the provisions of this
Section 5(c) shall be final, conclusive and binding upon Landlord and Tenant.
Tenant shall pay all fees, costs and expenses of Landlord and the Third Party
Accounting Firm in connection with the determination of any Rent/Termination
Value Adjustment. In the determination of any Rent/Termination Value Adjustment,
all assumptions set forth on Exhibit C shall continue to apply other than the
                             ---------
Inaccurate Assumption(s) resulting

                                      -5-
<PAGE>
 
in any Rent/Termination Value Adjustment.  From and after such Rent/Termination
Value Adjustment, Exhibit C shall be deemed amended so as to substitute the
                  ---------                                                
appropriate revised assumption for the Inaccurate Assumption.  In all cases, any
Rent/Termination Value Adjustment shall serve to preserve (but not improve or
adversely affect) Lessor's Anticipated Economics.  Unless a notice shall have
been given pursuant to this Section 5(c) by December 31 of the seventh calendar
year following the last calendar year in which a Federal Tax Law Change may
occur, the Rent/Termination Values then in effect shall be conclusive and
binding upon the parties for all purposes hereunder.

          (d)  With respect to any Rent Adjustment effectuated pursuant to this
Section 5 which has the effect of decreasing the amount of Basic Rent, the
amount of any such decrease in Basic Rent shall be limited as may be necessary
so that in no event shall the resulting amount of Basic Rent payable be an
amount which is less than the Debt Service Amounts payable; provided, however,
that an amount equal to the difference between (i) the full amount by which the
Basic Rent would have been decreased each month by such Rent Adjustment but for
such limitation, and (ii) the limiting Debt Service Amount (such difference
being hereinafter referred to as the "Unrealized Basic Rent Reduction Amount")
shall be periodically calculated by Landlord and a record thereof retained for
all periods during which the Basic Rent would, but for said limitation to the
Debt Service Amount, be less than the Debt Service Amount.  Any Unrealized Basic
Rent Reduction Amounts which may be created from time to time during the Term of
this Lease, plus an amount equal to three percent (3%) per annum calculated on
such Unrealized Basic Rent Reduction Amounts from the date each is created, are
hereinafter collectively referred to as the "Total Accumulated Credit Amounts."
In the event that any Extended Term is properly effected in accordance with the
terms of this Lease, Landlord shall grant Tenant a rent concession in the form
of no Basic Rent being payable from the first day of any such Extended Term, for
the period of time during which the total Basic Rent which would otherwise be
payable during such portion of the Extended Term equals the Total Accumulated
Credit Amounts; provided, however, that during any such portion of an Extended
Term when Total Accumulated Credit Amounts are applied in lieu of Basic Rent,
Additional Rent and any other amounts payable by Tenant in accordance with the
terms of this Lease during such portion of the Extended Term shall continue to
be due and payable.  In the event that Tenant purchases the Premises from
Landlord in accordance with any of the provisions of this Lease other than
provisions regarding (a) any condemnation of all or any portion of the Premises,
and (b) any default by Tenant in any of its obligations under this Lease, then,
to the extent that Total Accumulated Credit Amounts exist, not previously
credited against future Basic Rent as contemplated by the immediately preceding
sentence, Landlord shall reduce the purchase price in connection with such
purchase by an amount equal to the Total Accumulated Credit Amounts.
Notwithstanding anything in this subsection 5(d) to the contrary, in no event
shall Landlord be obligated to make any payments to Tenant or, other than as
expressly provided in this subsection 5(d), grant Tenant any rights or
concessions in connection with any Total Accumulated Credit Amounts or any
portion thereof.

          (e)  If any Rent Adjustment results in this Lease being characterized
as a "capital lease" for Tenant under FAS 13, as verified to Landlord and
Permitted Beneficiary in writing by Tenant's regularly retained independent
accounting firm, Tenant or Landlord may terminate this Lease within thirty (30)
days of such Rent Adjustment.  Any such termination of this Lease by Tenant
shall be effected only by Tenant paying to Landlord the applicable Termination
Value (as adjusted), the amount of the Lease Make-Whole Premium (as defined in
Section 32), the applicable Loan Make-Whole Premium (as defined in Section 32),
and all installments of Basic Rent, Additional Rent and all other sums then due
and payable hereunder to and including the date of termination, without offset
or deduction for any reason.  Tenant shall pay all charges, fees and expenses
incident to such termination by Tenant, including counsel fees and expenses, and
all applicable federal, state, and local taxes (other than any income or
franchise taxes levied upon or assessed against Landlord and those taxes assumed
in determining the Termination Value) which may be incurred or imposed by reason
of such termination.

          (f)  Subject to the provisions of subsection 5(d) above, the Basic
Rent payable by Tenant during any Extended Term of this Lease shall be an amount
equal to ninety-five percent (95%) of the then fair rental value of the Premises
(calculated without regard to the existence of this Lease) based upon rentals
for properties similar to the Premises in size, use and occupancy in the
Dallas/Fort Worth greater metropolitan area, determined at the beginning of each
such Extended Term by the procedure set forth on Attachment 3 to this Lease.
                                                 ------------               

          (g)  Any payment of a Termination Value made pursuant to this Lease
shall be made only on a date which is also a Basic Rent Payment Date.

          (h)  In the event that Landlord is entitled to any investment tax
credit due to or in connection with the acquisition of the Premises or the
construction of any improvements (whether Previous Construction, Renovations,
Permitted Alterations or other construction) performed on any portion of the
Premises, there shall be no Rent/Termination Value Adjustments caused thereby,
and Tenant shall not receive any advantage therefrom, whether in the form of
rent concessions, any other concessions with respect to any of Tenant's
obligations under this Lease, or otherwise; provided, however, that (A) if
Landlord is permitted and able to "pass through" to Tenant any such investment
tax credit without cost or expense of any kind to Landlord, Landlord shall do
so, so long as Landlord shall be satisfactorily indemnified by Tenant as to (1)
any recapture which may later result or be required, and (2) any other costs or
expenses which may be incurred by Landlord in connection with such transfer of
any such investment tax credit, and (B) to the extent that Landlord is unable to
"pass through" to Tenant any such investment tax credit as provided in (A) above
notwithstanding Tenant's satisfaction of the indemnification requirement set
forth above, Landlord shall, upon receipt from Tenant of a satisfactory
indemnification agreement indemnifying Landlord with respect to any recapture
which may later result or be required of Landlord because of such investment tax
credit, pay to Tenant an amount equal to any actual tax credit Landlord receives
and is able to apply, as a result of such investment tax credit, against tax
which would otherwise be payable,

                                      -7-
<PAGE>
 
which payment to Tenant shall be made within thirty (30) days after Landlord
files the subject tax return with the Internal Revenue Service.

          6.   Net Lease; Non-Terminability.
               ---------------------------- 

          (a)  This is an absolutely net lease to Landlord.  It is the intent of
the parties hereto that the Basic Rent payable under this Lease shall be an
absolutely net return to the Landlord and that Tenant shall pay all costs and
expense relating to the Premises and the business carried on therein, unless
otherwise expressly provided in this Lease.  Any amount or obligation herein
relating to the Premises which is not expressly declared to be that of the
Landlord shall be deemed to be an obligation of Tenant to be performed by Tenant
at Tenant's expense.  Basic Rent, Additional Rent and all other sums payable
hereunder by Tenant, shall be paid without notice (except as otherwise expressly
provided in subsection 5(b) with respect to interest on payments made by
Landlord), demand, setoff, counterclaim, abatement, suspension, deduction or
defense.

          (b)  This Lease shall not terminate, nor shall Tenant have any right
to terminate this Lease, nor shall Tenant be entitled to any abatement or
reduction of rent hereunder (except as otherwise expressly provided in
subsection 5(d) and subsection 14(c)), nor shall the obligations of Tenant under
this Lease be affected. by reason of (i) any damage to or destruction of all or
any part of the Premises from whatever cause; (ii) the taking of the Premises or
any portion thereof by condemnation, requisition or otherwise; (iii) the
prohibition, limitation or restriction of Tenant's use of all or any part of the
Premises, or any interference with such use; (iv) any eviction by paramount
title or otherwise; (v) Tenant's acquisition or ownership of all or any part of
the Premises otherwise than as expressly provided herein; (vi) any default on
the part of Landlord under this Lease, or under any other agreement to which
Landlord and Tenant may be parties; (vii) the failure of Landlord to deliver
possession of the Promises on the commencement of the term hereof; or (viii) any
other cause whether similar or dissimilar to the foregoing, any present or
future law to the contrary notwithstanding. It is the intention of the parties
hereto that the obligations of Tenant hereunder shall be separate and
independent covenants and agreements, that the Basic Rent, the Additional Rent
and all other sums payable by Tenant hereunder shall continue to be payable in
all events and that the obligations of Tenant hereunder shall continue
unaffected, unless the requirement to pay or perform the same shall have been
terminated pursuant to an express provision of this Lease. Notwithstanding
anything to the contrary contained above, Tenant does retain a separate and
independent right to sue the Landlord; provided, however, any judgment in favor
of Tenant shall not abate Basic Rent or Additional Rent or terminate Tenant's
obligations hereunder.

          (c)  Tenant agrees that it will remain obligated under this Lease in
accordance with its terms (except as otherwise expressly provided in subsection
5(d) and subsection 14(c)), and that it will not take any action to terminate,
rescind or avoid this Lease, notwithstanding (i) the bankruptcy, insolvency,
reorganization, composition, readjustment. liquidation, dissolution, or winding-
up or other proceeding affecting Landlord or its successors in interest, or (ii)
any

                                      -8-
<PAGE>
 
action with respect to this Lease which may be taken by any trustee or receiver
of Landlord or its successors in interest or by any court in any such
proceeding.

         (d)  Tenant waives all rights which may now or hereafter be conferred
by operation of law (i) to quit, terminate or surrender this Lease or the
Premises or any part thereof, or (ii) to any abatement, suspension, deferment or
reduction of the Basic Rent, Additional Rent or any other sums payable under
this Lease.

         (e)  If Landlord shall voluntarily breach its covenant of quiet
enjoyment under this Lease, Tenant's obligations under this Lease shall
thereafter be equitably and appropriately reduced by Landlord and Tenant to
reflect the effect of such breach by Landlord.

         7.   Taxes and Assessments; Compliance with Law; Environmental Matters.
              ----------------------------------------------------------------- 

         (a)  Tenant shall pay or discharge all Impositions, as hereinafter
defined, when due. Notwithstanding the foregoing provision of this subsection
7(a), the term "Imposition" shall not include and Tenant shall not be required
to pay any franchise, corporate, estate, inheritance, succession, transfer
(other than transfer taxes, recording fees, or similar charges payable in
connection with a conveyance hereunder to Tenant), income, excess profits or
revenue taxes of any Landlord hereunder, other than any gross receipts or
similar taxes imposed or levied upon, assessed against or measured by the Basic
Rent, Additional Rent or any other sums payable by Tenant hereunder or levied
upon or assessed against the Premises (unless such gross receipts or similar
taxes are in lieu of an income, profit or revenue tax of Landlord, but only to
the extent of such substitution and only to the extent that such tax, assessment
or other charge would be payable if the Premises were the only property of
Landlord subject thereto).  The exclusion contained in the immediately preceding
sentence shall not apply to any tax, assessment, charge or levy imposed or
levied upon or assessed against Landlord in substitution for or in place of an
Imposition.  Tenant agrees to furnish to Landlord, within thirty (30) days after
written demand therefor, evidence of the payment of all Impositions.  In the
event that any Imposition levied or assessed against the Premises becomes due
and payable during the Term hereof and may be legally paid in installments,
Tenant shall have the option to pay such Imposition in installments.  In such
event, Tenant shall be liable only for those installments which become due and
payable during the Term.  To the extent that any Impositions accrue during the
Term of this Lease but do not become due and payable until after the Term of
this Lease, and/or to the extent that Impositions are paid by Tenant which
relate to periods of time after the expiration of the Term of this Lease,
appropriate adjustments and prorations of the amounts of such Impositions shall
be made between Landlord and Tenant promptly after such expiration of the Term
of this Lease.

         (b)  Tenant shall, at its expense, comply with and, subject to the
provisions of the Environmental Indemnity Agreement (hereinafter defined) with
respect to the environmental matters which are Landlord's responsibility as
therein provided, shall take such action as is necessary to cause the Premises
to comply with, all restrictive covenants, private restrictions,

                                      -9-
<PAGE>
 
and governmental statutes, laws, rules, orders, regulations and ordinances, the
failure to comply with which at any time would affect the Premises or any part
thereof, or the use thereof, including those which require the making of any
structural, unforeseen or extraordinary changes, alterations, or repairs,
whether or not any of the same involve a change of policy on the part of the
body enacting the same, including, but not limited to the Americans With
Disabilities Act of 1990, 42 U.S.C. Section 12101 et seq., and any requirements
                                                  -- ---                       
of the State of Texas concerning accessibility standards for the handicapped,
including, without limitation, Tex. Rev. Civ. Stat. Ann. art. 601(b) (to the
extent applicable) and approval of plans and specifications by the Department of
Licensing and Regulation as required by Tex.  Rev.  Civ.  Stat.  Ann. art. 9102.
Tenant shall, at its expense, comply with and perform all changes required in
order to obtain the Required Insurance (as hereinafter defined), and with the
provisions of all contracts, agreements, instruments and restrictions existing
at the commencement of this Lease or thereafter suffered or permitted by Tenant
affecting the Premises or any part thereof or the ownership, occupancy or use
thereof.

         (c)  Tenant, Landlord and Principal Mutual Life Insurance Company have
executed and delivered to one another, contemporaneously with the execution and
delivery of this Lease, original counterparts of that certain Environmental
Indemnity Agreement, a copy of which is attached hereto as Exhibit L and made a
                                                           ---------           
part hereof for all purposes (the "Environmental Indemnity Agreement"), and the
provisions of which are incorporated herein by this reference.  To the extent
that the provisions of (A) this Section 7(c) and Section 32, and (B) the
Environmental Indemnity Agreement conflict, the Environmental Indemnity
Agreement shall control.  Tenant shall:

              (i)  not cause, suffer or permit a release or discharge of any
                   Hazardous Material (as defined in Section 32) at the Premises
                   (whether originating thereon or migrating to the Premises
                   from other property), or cause, suffer or permit any
                   Hazardous Material to be introduced to the Premises on or
                   after the date of this Lease, without the express prior
                   written approval of Landlord and Permitted Beneficiary, which
                   may be withheld without cause and in their sole discretion,
                   and shall promptly: (A) pay any claim against Tenant,
                   Landlord, Permitted Beneficiary or the Premises, (B) remove
                   any charge or lien upon any of the Premises, and (C) defend,
                   indemnify and hold Landlord and Permitted Beneficiary
                   harmless from any and all claims, expenses, liability, loss
                   or damage, resulting from any Hazardous Material released or
                   discharged at or from, or introduced to, the Premises (1) by
                   Tenant, on any date prior to the date of this Lease, or (2)
                   by Tenant or any other party on or after (but not prior to)
                   the date of this Lease;

             (ii)  not cause, suffer or permit any Hazardous Material to exist
                   on or discharge from any property owned or used by Tenant
                   which would result in any charge or lien upon the Premises
                   and shall promptly: (A)

                                      -10-
<PAGE>
 
                   pay any claim against Tenant, Landlord, Permitted Beneficiary
                   or the Premises, (B) remove any charge or lien upon the
                   Premises, and (C) defend, indemnify and hold Landlord and
                   Permitted Beneficiary harmless from any and all claims,
                   expenses, liability, loss or damage, resulting from the
                   existence of any such Hazardous Material;

            (iii)  notify Landlord and Permitted Beneficiary in writing of any
                   Hazardous Material that exists on or is released or
                   discharged from, at or onto the Premises (whether originating
                   thereon or migrating to the Premises from other property)
                   within ten (10) days after Tenant first has knowledge of such
                   existence of discharge;

             (iv)  comply, and cause the Premises to comply, with all statutes,
                   laws, ordinances, rules and regulations of all local, county,
                   state or federal authorities having authority over the
                   Premises or any portion thereof or their use; [and comply at
                   Tenant's sole cost and expense, with each and every
                   recommendation set forth in that certain report entitled
                   "Closure Confirmation Document" concerning the Premises
                   prepared by Albert H. Halff & Associates, Inc., dated April
                   1, 1993;]

              (v)  perform all of the environmental remediation work described
                   on Exhibit J attached hereto and made a part hereof (the
                      ---------
                   "Remediation") in a careful, proper and timely manner,
                   completing same no later than December 31, 1993, in
                   accordance with the specifications and requirements set forth
                   on Exhibit J hereto. and subject to Landlord's approval in 
                      ---------
                   its sole and absolute discretion. and the approval of such
                   inspecting environmental remediation experts as Landlord may
                   designate or employ; and

             (vi)  to the extent that the Renovations involve the installation
                   at the Premises of any underground storage tanks ("USTs"),
                   Tenant shall, in connection with any installation,
                   maintenance, operation and any future removal of such USTS,
                   comply in all respects with all applicable statutes, laws,
                   ordinances, rules, and regulations of all local, county,
                   state, or federal authorities having jurisdiction over the
                   USTs. Without limiting the foregoing, Tenant agrees that it
                   shall: (A) comply with the regulations, guidance documents,
                   and requirements of the Texas Water Commission ("TWC
                   Regulations") in the design, technical specifications,
                   installation, and operation of the USTs; (B) to the extent
                   registration is required, register the USTs as the operator
                   with the Texas Water Commission ("TWC"); (C) provide the
                   financial assurance required in connection with such

<PAGE>
 
                   Regulations; (E) at the option of Landlord, excavate, remove
                   and dispose of the USTs at the expiration or termination of
                   this Lease in full compliance with TWC regulations and
                   restore the area from which the USTs were removed to
                   substantially the same condition as before the USTs were
                   installed, it being understood and agreed that, if Landlord
                   elects not to require the removal of USTs as provided above,
                   the USTs shall be and thereafter remain the property of
                   Landlord after the expiration or termination of this Lease;
                   and (F) defend, indemnify, and hold Landlord and Permitted
                   Beneficiary harmless from any and all claims, expenses,
                   liability, costs, obligations, loss or damage arising in any
                   manner in connection with such USTs.

Tenant's obligations and liabilities under this subsection 7(c) shall survive
the expiration of this Lease.  The date of Tenant's satisfactory completion of
the Remediation as required by subsection 7(c)(v) above shall be the date upon
which Tenant delivers to Landlord, at Tenant"s sole cost and expense, an
environmental report acceptable in all respects to Landlord in the exercise of
its sole and absolute discretion, from an environmental audit firm designated by
Landlord, certifying to Landlord that the Remediation has been satisfactorily
completed; provided, however, that nothing herein shall be interpreted as
relieving Tenant of Tenant's obligation to complete the Remediation and to
deliver the report herein described on or before the date set forth above in
subsection 7(c)(v).

          8.  Indemnification.  Tenant agrees to pay, and to protect, defend,
              ---------------                                                
indemnify and save harmless Landlord, Permitted Beneficiary and their agents
from and against any and all liabilities, losses, damages, costs, expenses
(including all reasonable attorney's fees and expenses of Landlord), causes of
action, suits, claims, demands or judgments of any nature whatsoever (i) arising
from any injury to, or the death of, any person or damage to property on the
Premises or upon adjoining sidewalks, streets or right of ways, in any manner
growing out of or connected with the use, non-use, condition or occupation of
the Premises, adjoining sidewalks, streets or right of ways, so long as not
occasioned by a grossly negligent act of Landlord, Permitted Beneficiary, or
their agents, servants, employees or assigns, and/or (ii) arising from violation
by Tenant of any agreement or condition of this Lease, or any contract or
agreement to which Tenant is a party or any restriction, law, ordinance or
regulation, in each case affecting the Premises or any part thereof or the
ownership, occupancy or use thereof, so long as not occasioned by a grossly
negligent act of Landlord, Permitted Beneficiary, or their agents, servants,
employees or assigns.  If Landlord, Permitted Beneficiary or any agent of
Landlord or Permitted Beneficiary shall be made a party to any such litigation
commenced against Tenant, and if Tenant, at its expense, shall fail to provide
Landlord, Permitted Beneficiary or their agents with counsel (upon Landlord's
request) selected by Tenant, approved by Landlord, which approval shall not be
unreasonably withheld, Tenant shall pay all costs and attorneys' fees and
expenses incurred or paid by Landlord, Permitted Beneficiary or their agents in
connection with such litigation.  Tenant's obligations and liabilities under
this Section 8 shall survive the expiration or termination of this Lease.

          9.  Liens; Grants of Easements.
              -------------------------- 

          (a) Tenant will not, directly or indirectly, (i) create or permit to
be created, or (ii) except for those caused by Landlord's gross negligence,
permit to remain, and will promptly discharge, at its expense, any mortgage,
lien, encumbrance or charge on, pledge of, or conditional sale or other title
retention agreement with respect to, the Promises or any part thereof or
Tenant's interest therein or the Basic Rent, Additional Rent or other sums
payable by Tenant under this Lease, other than (1) any encumbrances permitted by
a Permitted Deed of Trust (as defined in subsection 32) and (2) any encumbrance
or charge permitted in the subsections below.  Nothing contained in this Lease
shall be construed as constituting the consent or request, expressed or implied,
by Landlord to or for the performance of any labor or services or of the
furnishing of any materials for any construction, alteration, addition, repair
or demolition of or to the Premises or any part thereof by any contractor,
subcontractor, laborer, materialman or vendor, except with respect to the
Previous Construction (hereinafter defined).  Notice is hereby given that
Landlord will not be liable for any labor, services or materials furnished or to
be furnished to Tenant, or to anyone holding the Premises or any part thereof,
and that no mechanic's or other liens for any such labor, services or materials
shall attach to or affect the interest of Landlord in and to the Premises.

          (b) Pursuant to an agreement with the prior owner of the Premises,
Tenant commenced construction of certain improvements prior to Landlord's
purchase of the Premises and prior to the date of this Lease (the "Previous
Construction"), and Tenant has indemnified Landlord and Principal Mutual Life
Insurance Company with respect to such Previous Construction by executing and
delivering to Landlord contemporaneously with the execution of this Lease that
certain Agreement Regarding Liens dated as of even date herewith.  Tenant
represents and warrants to Landlord that all costs of labor and material in
connection with the Previous Construction have been paid in full or will be paid
in full in a manner consistent with industry practice, from time to time as such
expenses become payable.  Tenant shall deliver lien waivers relating to all
portions of the Previous Construction, any Permitted Alterations, and all
portions of the Renovations (defined in Section 11 hereof) undertaken after the
date of this Lease.  Tenant covenants to pay all contractors, subcontractors,
materialmen and other parties providing labor, services or material in
connection with the Previous Construction, any Permitted Alterations and/or the
Renovations in a manner which is in accordance with industry practice, and to
take all actions to prevent any mechanic's or materialmen's liens or affidavits
in connection with the Previous Construction, any Permitted Alterations and/or
the Renovations from being recorded or remaining effective against any portion
of the Premises. Tenant will deliver to Landlord and Permitted Beneficiary no
sooner than 150 days after the completion of all Previous Construction, any
Permitted Alterations and the Renovations, respectively, and no later than 185
days after the completion of each, an abstractor's certificate or other title
update report, in form satisfactory to Landlord (a "Title Update"), together
with copies of all documents listed therein, which Title Update shall describe
all documents recorded in connection with the Premises since the date of this
Lease, and Tenant shall obtain

                                      -13-
<PAGE>
 
a release of or bond off of the Premises any mechanic's, materialmen's or other
lien described in the Title Update within 30 days after Tenant's receipt of the
Title Update.

          (c) Landlord hereby appoints Tenant its agent and attorney-in-fact and
authorizes Tenant (i) to grant easements, licenses, rights-of-way and other
rights and privileges in the nature of easements; (ii) to release existing
easements and appurtenances which are for the benefit of the Premises; and (iii)
to execute and deliver any instrument necessary or appropriate to confirm such
grants, releases or consents to any person, with or without consideration, in
each case, however, only if such action does not materially or adversely impact
the value of the Premises and only upon compliance with the provisions of any
Permitted Deed of Trust.  Tenant agrees that it will notify Landlord of any such
grant or release and will forward to Landlord promptly after the execution
thereof a copy of any instrument confirming such grant or release.  Any
consideration paid for such grant or release shall be apportioned between Tenant
and Landlord as their interests may then appear.  Tenant agrees that Tenant will
remain obligated under the terms of this Lease to the same extent as if such
easement, license, right-of-way, other right or privilege had not been granted,
such easement or appurtenance had not been released, such transfer had not been
consented to, and such instrument had not been executed and delivered, and that
Tenant will perform all obligations of the grantor, releasor or transferee under
such instrument of grant, release or consent.

          10.  Maintenance and Repair; Completion of Improvements.
               -------------------------------------------------- 

          (a) Tenant acknowledges that it has received the Premises in its "as
is" condition. Tenant agrees that. at its expense, it shall keep and maintain
the Premises, including any altered, rebuilt, additional or substituted
buildings, structures and other improvements thereto, in good repair and
appearance, except for ordinary wear and tear.  Tenant shall also make promptly
all structural and nonstructural, foreseen and unforeseen, ordinary and
extraordinary changes and repairs of every kind which may be required to be made
to keep and maintain the Premises in such good condition, repair and appearance
as a class A office facility, of similar size, use, occupancy and appearance,
located in the Dallas/Fort Worth greater metropolitan area, and Tenant will keep
the Premises orderly and free and clear of rubbish.  Tenant covenants to perform
or observe all terms, covenants or conditions of any reciprocal easement or
maintenance agreement to which it may at any time be a party or to which the
Premises are currently subject.  Tenant shall, at its expense, use its best
efforts to enforce compliance with any reciprocal easement or maintenance
agreement benefitting the Premises by any other person subject to such
agreement.  Landlord shall not be required to maintain, repair or rebuild, or to
make any alterations, replacements or renewals of any nature to the Premises, or
any part thereof, whether ordinary or extraordinary, structural or
nonstructural, foreseen or not foreseen to maintain the Premises or any part
thereof in any way.  Tenant hereby expressly waives the right to make repairs at
the expense of Landlord which may be provided for in any law in effect at the
time of the commencement of the Term or which may thereafter be

                                      -14-
<PAGE>
 
enacted.  If Tenant shall abandon the Premises, it shall give Landlord and any
Permitted Beneficiary immediate notice thereof.

          (b) If any Improvements situated on the Premises at any time during
the Term shall encroach upon any property, street or right-of-way adjoining or
adjacent to the Premises, or shall violate the agreements or conditions
contained in any restrictive covenant affecting the Premises or any part
thereof, or shall impair the rights of others under or hinder or obstruct any
easement or right-of-way to which the Premises are subject, then, promptly after
the written request of Landlord or any person affected by any such encroachment,
violation, impairment, hindrance or obstruction, Tenant shall, at its expense,
either (i) obtain effective waivers or settlements of all claims, liabilities
and damages resulting from each such encroachment, violation, impairment,
hindrance or obstruction whether the same shall affect Landlord, Tenant or both,
or (ii) make such changes in the improvements on the Premises and take such
other action as shall be necessary to remove such encroachments, hindrances or
obstructions and to end such violations or impairments, including, if necessary,
the alteration or removal of any improvement on the Premises.  Any such
alteration or removal shall be made in conformity with the requirements of
subsection 11(a) to the same extent as if such alteration or removal were an
alteration under the provisions of subsection 11(a).

          11.  Alterations.
               ----------- 

          (a) Subject to Tenant's covenants in Section 17, Tenant may, at
expense, at any time after written notice to Landlord and Permitted Beneficiary
of its plans (which notice shall include a description of the plans and
specifications for the proposed additions or alterations), but without the
consent of such parties other than the approval of the plans and specifications
therefor, make Permitted Alterations to the Premises, provided, that (i) all
Permitted Alterations are architecturally consistent with existing Improvements,
as verified by an architect's certificate addressed to Landlord and Permitted
Beneficiary, from a nationally recognized architectural firm; (ii) such actions
shall be performed in a good and workmanlike manner; (iii) such Permitted
Alterations shall be expeditiously completed in compliance with all laws,
ordinances, rules, regulations and requirements applicable thereto, (iv) whether
or not any subletting or assignment regarding any portion of the Premises has
occurred, any such Permitted Alterations, whether performed by any sublessee or
assignee, or by Tenant, shall not violate or be inconsistent with any of the Use
Restrictions, and (v) Tenant is otherwise in compliance with the provisions of
this Lease.  Tenant shall promptly pay all costs and expenses of each Permitted
Alteration, discharge all liens arising therefrom and procure and pay for all
permits and licenses required in connection therewith.

          (b) Subject to Tenant's covenants contained in Section 17, Tenant may,
at its expense, but only with Landlord's and Permitted Beneficiary's prior
written consent, construct upon the Promises additions to or alterations,
substitutions or replacements of the Improvements, other than Permitted
Alterations, upon compliance with all the terms and conditions set forth in
subsection 11(a).  Landlord's and Permitted Beneficiary's written

                                      -15-
<PAGE>
 
consent may be withheld or denied in the exercise of such parties' sole and
absolute discretion, and shall be granted only if such parties are able to
obtain the opinion of such parties' respective tax counsel that such additions,
alterations, substitutions or replacements by Tenant (other than Permitted
Alterations) will not result in Tenant obtaining an ownership interest in any
portion of the Premises, or result in any taxable income to Landlord.  Tenant
shall pay all costs, fees and expenses associated with obtaining such legal
opinions.  All Improvements [including, without limitation, those described in
Section 11(a)] shall be and remain part of the realty and the property of
Landlord and subject to this Lease.  Tenant may, at its expense, install,
assemble or place any items of trade fixtures, machinery or equipment upon the
Promises.  Such trade fixtures, machinery or equipment shall be and remain the
property of Tenant and Tenant may remove the same from the Premises at any time
prior to the termination of this Lease, provided that Tenant shall repair any
damage to the Premises resulting from such removal.  Notwithstanding anything in
this subsection 11(b) to the contrary, (i) so long as no default then exists
under this Lease, Tenant may, within thirty (30) days of the expiration or
termination of the Term of this Lease, remove (but shall not be obligated to
remove) from the Premises any trade fixtures of Tenant and such trade fixtures
so removed shall remain the property of Tenant, but any trade fixtures of Tenant
or other property not removed from the Premises within thirty (30) days of the
expiration or termination of the Term of this Lease shall immediately become the
property of Landlord, (ii) all costs of repair of the Premises necessitated by
Tenant's removal from the Premises of Tenant's trade fixtures or other property
shall be borne solely by Tenant, (iii) all costs of removal of any of Tenant's
trade fixtures or other property which is not removed from the Premises by
Tenant within thirty (30) days of the expiration or termination of this Lease,
as well as the cost of any repair of the remainder of the Premises necessitated
by any removal of such trade fixtures or other property by Landlord, shall be
borne solely by Tenant, and (iv) the provisions of this subsection shall survive
any expiration or termination of the Lease.

          (c) Subject to Tenant's covenants in Section 17, Tenant shall
construct and accomplish certain improvements, renovations and retrofitting in
connection with the Improvements (collectively the "Renovations") in accordance
with the plans and specifications described in the documents attached hereto and
made a part hereof as Exhibit K, and the development budget set forth on Exhibit
                      ---------                                          -------
I, which Renovations shall be completed no later than April 30, 1994, and
- -                                                                        
without any expenditures other than those specified in Exhibit I (except for
                                                       ---------            
expenditures for Permitted Alterations).  Tenant shall obtain all necessary
consents, permits, certificates, easements and approvals as may be necessary or
appropriate for the construction and/or completion of the Renovations.  Landlord
shall pay to Tenant for construction of the Renovations on behalf of Landlord
and for the Fees and Costs (as defined in Section 32), the amount of
$15,932,616.00 contemporaneously with the execution of this Lease (the
"Renovation Cost").  The cost of the Renovations, all Fees and Costs, and any
related costs shall not, in the aggregate, exceed the Renovation Cost except to
the extent that the Renovations constitute Permitted Alterations.  In the event
that any portion of the Renovation Cost remains unspent by Tenant after
completion of the Renovations, any such remaining funds shall be repaid to
Landlord, the Basic Rent and Termination Values shall be

                                      -16-

adjusted as provided in Section 5 of this Lease (due to the change in the
assumption as to the cost of the Renovations), and Tenant shall pay to Landlord
with the payment of such remaining funds (i) a Lease Make Whole Premium, and
(ii) any Loan Make-Whole Premium. Monthly during the course of the construction
of the Renovations, Tenant shall deliver to Landlord and Permitted Beneficiary
(and, upon direction by Landlord and/or Permitted Beneficiary, any title company
as may be designated) as evidence of the application by Tenant of portions of
the Renovation Cost toward the completion of the Renovations (1) American
Institute of Architects form draw requests, completed and executed by Tenant's
supervising architect, (2) a certification executed by Tenant, addressed to
Landlord and Permitted Beneficiary, specifying with respect to the Development
Budget set forth on Exhibit I, and with respect to the categories set forth on
                    ---------                                                 
Attachment 2, the category of each expenditure during such month, the amount
- ------------                                                                
previously expended with respect to each such category, and the amount which
will be necessary to be expended to complete the items designated in each such
category, and (3) lien waivers executed by the contractors, subcontractors and
materialmen with respect to all expenditures indicated in the documentation
described in (1) and (2) above, in form and substance reasonably satisfactory to
Landlord and Permitted Beneficiary.  From time to time during the construction
of the Renovations, and upon completion of the Renovations, Tenant will deliver
to the title company designated by Landlord and Permitted Beneficiary, lien
waivers and other documentation as may be required by such title company, and
take such other action as may be necessary (including, without limitation,
payment of any premiums and other charges by the title company) (A) to obtain
and deliver to Landlord and Permitted Beneficiary, respectively, endorsements to
Landlord's Owner Policy of Title Insurance and Permitted Beneficiary's Mortgagee
Policy of Title Insurance received contemporaneously with the execution and
delivery of this Lease, increasing the coverage thereof to the extent of amounts
paid for construction of the Renovations, and (B) upon completion of the
Renovations, to increase the actual coverage of each of such policies to the
full face amount of each of such policies as set forth on Schedule A thereto,
and to delete from both of such title insurance policies any "pending
disbursements" exception and any "completion of improvements" exception, without
inclusion of any exceptions to either of said policies not present on the date
of the original issuance of such policies.  In the event that all of the
Renovations are not completed and the Renovations and all other portions of the
Improvements "placed in service" (as that term is used in the Code, hereinafter
referenced as "Placed In Service") on or before April 30, 1994 (the "Renovation
Deadline"), Tenant shall purchase the Premises from Landlord for a purchase
price equal to the Termination Value, plus a Lease Make Whole Premium, plus any
Loan Make Whole Premium, plus any taxes not imputed into the Termination Value;
provided, however, that the Renovation Deadline may, at Tenant's option, be
extended by Tenant until October 30, 1994, by paying an extension fee to
Landlord equal to one half of one percent (.5%) of the total amount of
Landlord's investment in the Premises (including all acquisition costs and the
Renovation Cost), plus all expenses incurred in connection with any such
extension, so long as the Basic Rent and Termination Values are adjusted, if
necessary, as set forth in Section 5 of this Lease. The date on which the
Renovations are Placed in Service shall be conclusively determined by the date
on which Tenant delivers to Landlord a certificate of occupancy for all

component depreciation assumptions described in Exhibit C of this Lease or, if

Renovations as completed, shall be accomplished, and, as to each such building
after its completion, shall be effected by (I) the delivery by Tenant to
Landlord of a certificate addressed to Landlord, describing all actual costs
incurred to date in connection with the Renovations and allocating all of such
costs among the various categories of expenditures described in Attachment 2,
                                                                ------------

Landlord contemporaneously with the execution of this Lease, prepared by Artura
Singer and Harry Schroeder of Joseph J. Blake & Associates, Inc. containing a
valuation dated as of April 1, 1993 (the "April, 1993 Appraisal").  The form of
said certificates and appraisal updates is to be satisfactory to Landlord in its
sole discretion, and such items are to be delivered for the purpose of
confirming that such Renovations have been completed in accordance with Exhibit
                                                                        -------

incurred in completing such Renovations, and calculating any necessary
Rent/Termination Value Adjustments as may be appropriate in accordance with the
provisions of Section 5(c) of this Lease as a result of the information set
forth on such updated appraisals and certificates delivered to Landlord.  The
appraisal updates are not intended to adjust the specific items from one
depreciable class to another.  Notwithstanding anything in this Lease to the
contrary, in addition to the requirements set forth above, all Renovations shall
be completed in a manner reasonably satisfactory to Landlord, and Landlord shall
have the right, from time to time, to inspect the progress of the Renovations
and to require correction of any defects or deficiencies or any non-compliance
with the plans and specifications attached to this Lease in Exhibit K or with

respect to (i) the source of funds to be used, or (ii) the cost of construction
of improvements by Tenant or the cost of completion of the Renovations by
Tenant, Tenant may, without Landlord or Permitted Beneficiary's prior consent,
but in any event subject to the provisions of Section 17 of this Lease, expend
Tenant's own funds for construction of Permitted Alterations.

          12.  Insurance.  (a)  Tenant shall maintain, or cause to be
               ---------                                             
maintained, at its sole expense, the following insurance on the Premises (the
"Required Insurance"):

               (i)  Property insurance insuring the building and improvements
                    for perils covered by the causes of loss - special form (all
                    risk) and in addition, ordinance or law coverage, flood,
                    earthquake and boiler and machinery (if applicable). Such
                    insurance shall be written on a replacement cost basis with
                    an agreed value equal to the full insurable replacement
                    value of the foregoing. The policy shall name Landlord as an
                    additional insured and loss payee and all Permitted
                    Beneficiaries or mortgagee of any deed of trust or mortgage
                    encumbering the Premises shall be shown as a mortgage
                    holder. Not more frequently than every year if in the
                    opinion of the Landlord, the amount of Tenant's property
                    insurance is found to be inadequate, Tenant will increase
                    the insurance Amount as required by the Landlord.

              (ii)  Commercial general liability insurance naming the Landlord
                    and Permitted Beneficiary as additional insureds against any
                    and all claims as are customarily covered under a standard
                    policy form routinely accepted by Permitted Beneficiary, for
                    bodily injury and property damage occurring in, or about the
                    Premises arising out of Tenant's use and occupancy of the
                    Premises. Such insurance shall have a combined single limit
                    of not less than Two Million Dollars ($2,000,000) per
                    occurrence with a Twenty Million Dollar ($20,000,000)
                    aggregate limit and excess umbrella liability insurance in
                    the amount of at least Five Million Dollars ($5,000,000).
                    Tenant shall be required to increase its insurance limits as
                    may be required from time to time by the Permitted
                    Beneficiary or as may reasonably be required by Landlord
                    consistent with coverage on properties similarly
                    constructed, occupied and maintained. Such liability
                    insurance shall be primary and not contributing to any
                    insurance available to Landlord and Landlord's insurance
                    shall be in excess thereto. In no event shall the limits of
                    such insurance be considered as limiting the liability of
                    Tenant under this Lease.

             (iii)  Workers' compensation insurance in accordance with statutory
                    law and employers' liability insurance with a limit of not
                    less than $100,000 per employee and $500,000 per occurrence.

              (iv)  Builders risk insurance insuring perils covered by the
                    causes of loss-special form (all risk) shall be purchased
                    for the value of the alteration and/or additions made to the
                    Premises when the work is not insured under Tenant's
                    property insurance policy.

               (v)  Such other insurance as Landlord may, from time to time,
                    reasonably require, or which may, from time to time, be
                    required by Landlord's beneficiaries or mortgagees of any
                    deed of trust or mortgage encumbering the Premises, so long
                    as such other insurance is customarily required to be
                    carried on similar properties by institutional lenders in
                    the industry.

          (b)  The policies required to be maintained by Tenant shall be with
companies having a rating of not less than A with a financial class of at least
X in the most current issue of Best's Insurance Reports.  Insurers shall be
licensed to do business in the state in which the Premises are located and
domiciled in the USA.  Any deductible amounts under any insurance policies
required hereunder shall not exceed (1) $500,000.00, so long as Tenant's
financial condition is rated not less than "BBB+" by Standard & Poor's
Corporation and "Baa1" by Moody's Investment Service; (2) $250,000.00, so long
as Tenant's financial condition is rated not less than "BBB" by Standard &
Poor's Corporation and "Baa2" by Moody's Investment Service; (3) $100,000.00, so
long as Tenant's financial condition is rated not less than "BBB-" by Standard &
Poor's Corporation and "Baa3" by Moody's Investment Service; or (4) $5,000.00,
at any time during which Tenant's financial condition is rated less than "BBB-"
by Standard & Poor's Corporation or "Baa3" by Moody's Investment Service.
Certificates of insurance shall be delivered to Landlord prior to the
commencement date and annually thereafter at least fifteen (15) days prior to
the expiration date of the old policy.  Tenant shall have the right to provide
insurance coverage which it is obligated to carry pursuant to the terms hereof
in a blanket policy, provided such blanket policy expressly affords coverage to
the Premises and to Landlord as required by this Lease.  Each policy of
insurance shall provide notification to Landlord at least thirty (30) days prior
to any cancellation or modification to reduce the insurance coverage.

          (c)(i) Insurance claims by reason of damage to or destruction of any
portion of the Premises shall be adjusted by Tenant; provided, however, that
although Tenant shall make the final decision with respect to any such
adjustment, Tenant shall, promptly after such damage or destruction, advise
Landlord and Permitted Beneficiary of such occurrence and consult with Landlord
and Permitted Beneficiary throughout the process of adjusting any such claim,
and provided further that both Landlord and any Permitted Beneficiary shall have
the right to be and remain involved in the adjustment process and to receive
copies of all correspondence and documentation pertaining thereto.  Tenant shall
keep Landlord and Permitted Beneficiary fully advised as to all matters on a
current basis.  Landlord shall not be required to prosecute any claim against,
or to contest any settlement proposed by, an insurer.  Tenant may, at its
expense, prosecute, any such claim or contest any such settlement in the name of
Landlord, Tenant or both, and Landlord will join therein at Tenant's written
request upon the receipt by Landlord of an indemnity from Tenant against all
costs, liabilities and expenses in connection therewith.

                                      -20-
<PAGE>
 
          (c)(ii) Subject to the provisions of Section 13, proceeds from the
property insurance policy shall be made available from Landlord or Permitted
Beneficiary to Tenant, but only against certificates of Tenant delivered to
Landlord from time to time as such work or repair progresses, each such
certificate describing the work or repair for which Tenant is requesting payment
and the cost incurred by Tenant in connection therewith and stating that Tenant
has not theretofore received payment for such work and has sufficient funds
remaining to complete the work free of liens or claims. Subject to the
provisions of Section 13, any proceeds remaining after Tenant has repaired the
Premises pursuant to Section 13 shall be delivered to Tenant but only to the
extent that the aggregate amount of such proceeds so remaining and all amounts
theretofore paid to Tenant pursuant to this sentence do not exceed $100,000.00.
If such aggregate amounts exceed $100,000.00, the excess may be retained by
Landlord and applied in reduction of the principal amount of the indebtedness
secured by any Permitted Deed of Trust or paid to Tenant at Landlord's sole
option. After the retention of any such amount by Landlord, each installment of
Basic Rent payable on and after the second Basic Rent Payment Date occurring
after such retention shall be equitably reduced but in no event shall Basic Rent
be reduced lover than the monthly debt service payments due under any Permitted
Deed of Trust. No payment shall be made to Tenant pursuant to this subsection
12(c) if any default shall have happened and be continuing under this Lease.
Notwithstanding anything herein to the contrary, this subsection (c)(ii) shall
not apply or have any effect at any time during which Tenant's financial
condition is rated no less than "BBB" by Standard & Poor's Corporation and
"Baa2" by Moody's Investment Service.

          (d) In the event Tenant does not purchase the insurance required by
this Lease or keep the same in full force and effect, Landlord may, but shall
not be obligated to, purchase the necessary insurance and pay the premium.
Tenant shall repay to Landlord, as Additional Rent, the amount so paid promptly
upon demand. In addition, Landlord may recover from Tenant and Tenant agrees to
pay, as Additional Rent, any and all reasonable expenses (including attorneys'
fees) and damages which Landlord may sustain by reason of the failure to Tenant
to obtain and maintain such insurance.

          (e) Landlord or Permitted Beneficiary shall not be limited in the
proof of any damages which Landlord or Permitted Beneficiary may claim against
Tenant arising out of or by reason of Tenant's failure to provide and keep in
force insurance, as provided above, to the amount of the insurance premium or
premiums not paid or incurred by Tenant and which would have been payable under
such insurance; but Landlord and Permitted Beneficiary shall also be entitled to
recover as damages for such breach, the uninsured amount of any loss, to the
extent of any deficiency in the Required Insurance and damages, costs and
expenses of suit suffered or incurred by reason of or damage to, or destruction
of, provide the Required Insurance. Tenant shall indemnify and hold harmless
Landlord and Permitted Beneficiary for any liability incurred by Landlord or
Permitted Beneficiary arising out of any deductibles for Required Insurance.

                                      -21-

          (f)  Provided (i) no Event of Default has occurred and is continuing;
(ii) Tenant maintains a Consolidated Tangible Net Worth of at least
$750,000,000.00 determined in accordance with generally accepted accounting
principals; and (iii) Tenant's financial condition is not rated less than "BBB+"
by Standard & Poor's Corporation and "Baa1" by Moody's Investment Service,
Tenant may self-insure the Required Insurance. Tenant shall provide annually to
the Landlord a certificate indicating its decision to self-insure in the form
attached hereto as Exhibit E. For purposes of this subsection (f), the term
                   ---------                                
"Consolidated Tangible Net Worth" shall mean "equity, plus the liability
appearing on the balance sheet of Tenant for post retirement benefits other than
pensions recorded in accordance with Statement of Financial Accounting Standards
No. 106, less net intangibles arising from acquisitions (or goodwill)"
calculated as of the end of each fiscal quarter year. Notwithstanding anything
in this subsection 12(f) to the contrary, in the event that a breach of this
subsection 12(f) is caused solely by the effect of a future change in accounting
principle, Landlord agrees to negotiate with Tenant in good faith to resolve
and/or remedy such breach.

          13.  Casualty.
               -------- 

          (a)  If, during the Primary Term, a part of the Premises shall be
damaged or destroyed by casualty, and if the estimated cost of rebuilding,
replacing and repairing the same shall be or exceed $100.000.00, Tenant shall
promptly notify Landlord and Permitted Beneficiary thereof; and (whether or not
such estimated cost shall be or exceed $100,000.00 and whether or not all or a
portion of the Premises is destroyed) Tenant shall, with reasonable promptness
and diligence, rebuild, replace and repair any damage or destruction to the
Premises, at its expense, in conformity with the requirements of subsection
11(a) in such manner as to restore the same to the same condition, as nearly as
possible, as existed prior to such casualty and there shall be no abatement of
Basic Rent or Additional Rent.

          (b)  If, after the Primary Term and during any Extended Term, the
Premises is substantially (75% of the Improvements) or totally destroyed by
casualty, Tenant shall have the option to either (i) rebuild or restore the
Premises and receive the necessary portion of the insurance proceeds generated
therefrom to pay for such rebuilding or restoration, or (ii) terminate this
Lease not less than one (1) year after delivery of notice to Landlord of
Tenant's intention to do so and upon payment to Landlord of all amounts then due
and payable under this Lease, with all insurance proceeds being paid to and
retained by Landlord, or, in the event of and to the extent of self insurance,
an amount equal to the insurance proceeds which would have been available if
insurance coverage had then been in place.

          (c)  Notwithstanding anything in this Section 13 to the contrary,
during any period of time when there continues to exist a default by Tenant
under the terms of this Lease, Landlord, in the exercise of its sole and
absolute discretion, shall have the right to receive any insurance proceeds from
any casualty and to apply same toward payment of any indebtedness owed to any
Permitted Beneficiary instead of allowing such proceeds to be used by Tenant for
the rebuilding or restoration of the damaged portion of the Premises. In such
event, there

                                      -22-
<PAGE>
 
shall be an equitable adjustment in the Rent/Termination Value after any cure of
such default, to become effective as of the date of such cure.

          14.  Condemnation.
               ------------ 

          (a)  Subject to the rights of Tenant set forth in this Section 14,
Tenant hereby irrevocably assigns to Landlord any award or payment to which
Tenant may be or become entitled with respect to the taking of the Premises or
any part thereof, by condemnation or other eminent domain proceedings pursuant
to any law, general or special, or by reason of the temporary taking of the use
or occupancy of the Premises or any part thereof, by any governmental authority,
civil or military, whether the same shall be paid or payable in respect of
Tenant's leasehold interest hereunder or otherwise. Landlord shall be entitled
to participate in any such proceeding and the expenses thereof (including
counsel fees and expenses) shall be paid by Tenant.

          (b)  (1) If, during the Primary Term (i) the entire Premises shall be
taken by or on account of any actual or threatened condemnation or other eminent
domain proceeding pursuant to any law, general or special or (ii) if 25% of the
Improvements or 50% of the Land Parcel is taken and said portion renders the
remaining premises uneconomic for the continued use or occupancy in the business
of Tenant, in the good faith judgment of Tenant's Board of Directors, Tenant's
Chief Executive Officer, or the Executive Vice President of TRW Information
Systems and Services, then Tenant shall deliver a Purchase Offer (as defined in
Section 32) to Landlord, specifying a termination date (the "Termination Date")
occurring not less than one (1) year after the delivery of such Purchase Offer
and a purchase price equal to the Termination Value plus all other amounts then
due and payable under this Lease, and this Lease shall continue in full force
and effect without any abatement of rent, notwithstanding any taking, until the
Termination Date. The Purchase Offer shall be for a purchase of the Premises and
any Net Award (as hereinafter defined) and shall be accompanied by a Tenant's
Certificate stating either that the conditions set forth in clause (i) or (ii)
of this subsection 14(b)(1) have been fulfilled. If the conditions set forth in
clause (i) or (ii) of this subsection 14(b)(1) are fulfilled and if Tenant shall
have failed to deliver a Purchase Offer as required above, Tenant conclusively
shall be presumed to have made a Purchase Offer on a date which is sixty (60)
days after any such taking (or such later date as is agreed to in writing by
Landlord), and in the event Tenant is so presumed to have made a Purchase Offer,
the Termination Date shall be deemed to be ninety (90) days after such Purchase
Offer is presumed to have been made; but nothing in this sentence shall relieve
Tenant of its obligation actually to deliver such Purchase Offer.

          (b) (2) If, after the Primary Term and during any Extended Term, the
Premises is substantially (25% of the Improvements or 50% of the Land Parcel) or
totally condemned or taken pursuant to other eminent domain proceedings, Tenant
shall have the option to either (i) rebuild or restore the Premises to the
extent possible and receive the necessary portion of the proceeds from the
condemnation or other eminent domain proceedings, or (ii) terminate this

                                      -23-
<PAGE>
 
Lease not less than one (1) year after delivery of notice to Landlord of
Tenant's intention to do so and upon payment to Landlord of all amounts then due
and payable under this Lease, with all condemnation or other eminent domain
proceeds being paid to and retained by Landlord.

     (c) If during any Term (i) a portion of the Premises shall be taken by
condemnation or other eminent domain proceedings, which taking is not sufficient
to require that Tenant give a Purchase Offer or (ii) the use or occupancy of the
Premises or any part thereof shall be temporarily taken by any governmental
authority; then this Lease shall continue in full effect without abatement or
reduction of Basic Rent, Additional Rent or other sums payable by Tenant
hereunder notwithstanding such partial or temporary taking.  Tenant shall,
promptly after any such temporary taking ceases, at its expense, repair any
damage caused thereby in conformity with the requirements of subsection 11(a) so
that, thereafter, the Premises shall be, as nearly as possible, in a condition
as good as the condition thereof immediately prior to such taking.  In the event
of any such partial taking, Landlord shall make the Net Award (as hereinafter
defined) available to Tenant to make such repair but, if such Net Award shall be
in excess of $250,000.00, only against certificates of Tenant delivered to
Landlord from time to time as such work or repair progresses, each such
certificate describing the work or repair for which Tenant is requesting payment
and the cost incurred by Tenant in connection therewith and stating that Tenant
has not theretofore received payment for such work.  Any Net Award remaining
after such repairs have been made, shall be delivered to Tenant; but only to the
extent that the aggregate amount of such Net Award so remaining and all amounts
theretofore paid to Tenant pursuant to this sentence do not exceed $250,000.00.
If such amounts exceed $250,000.00, the excess may be retained by Landlord and
applied in reduction of the principal amount of the indebtedness secured by any
Permitted Deed of Trust then outstanding at Landlord's sole option.  If Landlord
retains any such amount the Basic Rent payable on or after the second Basic Rent
Payment Date occurring after such retention shall be reduced equitably, but in
no event shall the Basic Rent be reduced to an amount less than the Debt Service
Amounts.  In the event of such temporary requisition, Tenant shall be entitled
to receive the entire Net Award payable by reason of such temporary requisition
or portion of such temporary requisition occurring during the term hereof, less
any costs incurred by the Landlord in connection therewith.  If the cost of any
repairs required to be made by Tenant pursuant to this subsection 14(c) shall
exceed the amount of the Net Award, the deficiency shall be paid by Tenant.
Notwithstanding anything herein to the contrary, no payments shall be made to
Tenant pursuant to this subsection 14(c) if any default or Event of Default
shall have happened and shall be continuing under this Lease.

     (d) For the purposes of this Lease the term "Net Award" shall mean:  (i)
all amounts payable as a result of any condemnation or other eminent domain
proceeding, less all expenses for such proceeding not otherwise paid by Tenant
in the collection of such amounts, plus (ii) all amounts payable pursuant to any
agreement with any condemning authority (which agreement shall be deemed to be a
taking) which has been made in settlement of or under threat of any condemnation
or other eminent domain proceeding affecting the Premises, less all

                                      -24-
<PAGE>
 
expenses incurred as a result thereof not otherwise paid by Tenant and the
collection of such amounts.

     (e) Any minor condemnation or taking of the Premises for the construction
or maintenance of streets or highways shall not be considered a condemnation or
taking for purposes of this Section 14 so long as the Premises shall not be
materially or adversely affected, ingress and egress for the remainder of the
Premises shall be adequate for the business of Tenant and the provisions of any
Permitted Deed of Trust relating thereto shall be complied with.  Tenant agrees
that it will notify Landlord of any such condemnation.

     (f) Notwithstanding anything in this Section 14 to the contrary, during any
period of time when there continues to exist a default by Tenant under the terms
of this Lease, Landlord, in the exercise of its sole and absolute discretion,
shall have the right to receive any Net Award and to apply same toward payment
of any indebtedness owed to any Permitted Beneficiary instead of allowing such
Net Award to be used by Tenant for the rebuilding or restoration of any affected
portion of the Premises.  In such event, there shall be an equitable adjustment
in the Rent/Termination Value after any cure of such default, to become
effective as of the date of such cure.

     15.  Procedure After Purchase Offer; Procedure in Event of Purchase.
          -------------------------------------------------------------- 

     (a) If Landlord shall reject any Purchase Offer not later than the tenth
(10th) day prior to the Termination Date or purchase date specified in such
Purchase Offer, this Lease shall terminate on such date (except with respect to
obligations and liabilities of Tenant under this Lease, actual or contingent,
which have arisen on or prior to such termination, all of which shall survive
any termination of this Lease), upon payment by Tenant of the Basic Rent,
Additional Rent and all other sums then due and payable hereunder to and
including the date of termination without offset or deduction for any reason.
Upon a purchase of the Premises pursuant to subsection 14(c) and the payment to
the Landlord of the purchase price set forth on Exhibit F, Landlord shall convey
                                                ---------                       
the Premises and all its right, title and interest in and to the Net Award
(whether or not such Award shall have been received by Landlord), to Tenant or
its designee, as provided in subsections 15(b), 15(c) and 15(e) below.

     (b) If the Premises or any part thereof shall be purchased by Tenant
pursuant to any provision of this Lease, Landlord need not transfer and convey
to Tenant or its designee any better title thereto than existed on the date of
the commencement of this Lease, and Tenant shall accept such title subject to
such liens, encumbrances, charges, exceptions and restrictions on, against or
relating to the Premises (including those arising pursuant to the terms of this
Lease) and to all applicable laws, regulations and ordinances, but free of the
Permitted Deed of Trust and all other mortgages, liens, encumbrances, charges,
exceptions and restrictions which shall have been created by or resulted from
acts or failures to act of Landlord.
     (c) On the date fixed for any such purchase, Tenant shall pay to Landlord,
at any place within the United States of America designated by Landlord, the
applicable purchase

                                      -25-
<PAGE>
 
price set forth on Exhibit F therefor, together will all installments of Basic
                   ---------                                                  
Rent and all other sums then due under this Lease and unpaid to and including
the date of purchase without offset or deduction for any reason, and Landlord
shall deliver to Tenant a special warranty deed conveying title to the Premises
of the character described in subsection 15(b) above and subsection 15(e) below,
and describing the Premises or portion thereof being sold and conveying the
title thereto, together with such instruments as shall be necessary to transfer
to Tenant or its designee any other property then required to be transferred by
Landlord pursuant to this Lease.  Tenant shall pay all charges incident to such
conveyance and transfer, including counsel fees, escrow fees, recording fees,
title insurance premiums and all applicable federal, state and local taxes
(other than any income or franchise taxes levied upon or assessed against
Landlord) which may be incurred or imposed by reason of such conveyance and
transfer (collectively, the "Transfer Costs").

     (d) Upon the completion of such purchase, but not prior thereto (whether or
not any delay in the completion of, or the failure to complete such purchase
shall be the fault of Landlord), this Lease and all obligations hereunder
(including the obligations to pay Basic Rent and Additional Rent) shall
terminate, except with respect to (i) obligations and liabilities of Tenant,
actual or contingent, under this Lease which arose on or prior to such date of
purchase, (ii) those obligations contained in subsection 7(c) and Section 8,
(iii) the Environmental Indemnity Agreement, and (iv) those obligations which
are to survive the expiration or termination of this Lease as expressly provided
by the terms of this Lease.

     (e) The special warranty deed to be delivered pursuant to Section 15(c)
above shall contain, without limitation, the following provisions: "(a) GRANTEE

     16.  Assignment and Subletting.  Tenant may sublet all or any part of the
          -------------------------                                           
Premises and may assign all of its rights and interests under this Lease without
the consent of Landlord, so long as (i) each such sublease or assignment shall
expressly be made subject to the provisions of this Lease, (ii) any such
sublessee or assignee shall, upon request of Permitted Beneficiary, execute a
Non-Disturbance and Attornment Agreement with Landlord and any Permitted
Beneficiary as may be reasonably required by either of such parties, (iii)
Tenant shall remain primarily liable to Landlord under this Lease and Tenant's
liability shall not in any way be reduced, limited or released, (iv) any such
sublease or assignment has no adverse impact or effect on any tax treatment of
Landlord in connection with the Premises or any transaction, (v) any such

than 15,000 square feet of the leased space of the Premises, or have the effect
of creating more than a total of five (5) parties then having an interest in the
Premises as a tenant, subtenant and/or assignee.  If Tenant assigns all its
rights and interests under this Lease, the assignee under such assignment shall
expressly assume all the obligations of Tenant hereunder in an instrument,
approved by Landlord as to form and substance (which approval will not be
unreasonably withheld or delayed), delivered to Landlord at the time of such
assignment.  No assignment or sublease made as permitted by this Section 16
shall affect or reduce any of the obligations of Tenant hereunder, and all such
obligations shall continue in full force and effect as obligations of a
principal and not as obligations of a guarantor or surety, to the same extent as
though no assignment or subletting had been made; provided that performance by
any such assignee or sublessee of any of the obligations of Tenant under this
Lease shall be deemed to be performance by Tenant.  No sublease or assignment
made as permitted by this Section 16 shall impose any obligations on Landlord or
otherwise affect any of the rights of Landlord under this lease.  Neither this
Lease nor the Term hereby demised shall be mortgaged, pledged or hypothecated by
Tenant, nor shall Tenant mortgage or pledge the interest of Tenant in and

                                      -28-
<PAGE>
 
to any sublease of the Premises or the rentals payable thereunder.  Any
mortgage, pledge, sublease or assignment made in violation of this Section 16
shall be void.  Tenant shall, within ten (10) days after the execution and
delivery of any such assignment or sublease of all or substantially all of the
Premises, deliver a conformed copy thereof to Landlord.  Within ten (10) days
after the execution and delivery of any sublease of a portion of the Premises,
Tenant shall give notice to Landlord of the existence and term thereof, and of
the name and address of the sublessee thereunder.  Notwithstanding anything in
this Lease to the contrary, Tenant shall not sublease any portion of the
Premises or assign this Lease if the effect of such sublease or assignment would
be to cause the Premises or any portion thereof to be considered as being
property used by a tax-exempt entity or other entity, with the result that some
or all of the federal, state or municipal income tax deductions which Landlord
otherwise would be permitted to report with respect to the Premises or with
respect to the Lease would be deferred or denied, or cause this Lease not to be
considered as a true lease for federal income tax purposes.

     17.  Additional Tenant Covenants and Representations.  Notwithstanding any
          -----------------------------------------------                      
other provisions of this Lease to the contrary, Tenant covenants and represents
to Landlord and to Permitted Beneficiary as follows:

     (a) Except as may be otherwise expressly provided in Section 11 of this
Lease with respect to Permitted Alterations, Tenant shall not expend any of
Tenant's funds for any portion of the Renovations or for the Fees and Costs,
without the prior written consent of Landlord and Permitted Beneficiary (which
consent may be withheld or denied by such parties in their sole and absolute
discretion), and the total cost of all Renovations shall be provided by Landlord
in the amounts set forth on the development budget attached hereto as Exhibit I;
                                                                      ----------

     (b) The Premises are currently and, after the Renovations are complete,
will be susceptible to use by parties other than Tenant;

     (c) Tenant shall, at all times and for all purposes, treat this Lease as
and consider it to be an operating lease, including, without limitation, for
purposes of all federal income tax returns, and all reports and information
supplied or reported to the Internal Revenue Service; and

     (d) Tenant shall not make any Permitted Alterations, Renovations,
improvements, alterations, additions, replacements or substitutions to or of any
portion of the Premises which could (i) constitute or be construed as taxable
income to Landlord, (ii) result in some or all of the federal, state or
municipal income tax deductions which Landlord would otherwise be permitted to
report with respect to Premises or this Lease being deferred or denied, (iii)
cause Tenant to be deemed to have acquired an interest in the fee title to the
Premises, or (iv) cause this Lease not to be considered as a true lease for
federal income tax purposes.
     18.  Financial Statements.

inspect the Premises, at all reasonable times and as often as may be reasonably
requested.  Tenant shall also provide to Landlord and/or Permitted Beneficiary
any information regarding the business, affairs or financial condition of Tenant
as Landlord or Permitted Beneficiary may reasonably request from time to time
including, but not limited to, any information requested of Landlord or
Permitted Beneficiary from (i) a governmental agency having jurisdiction over
Landlord or Permitted Beneficiary, (ii) any investment financial rating service
such as Standard & Poor's Corporation or Moody's Investment Service, or (iii)
the United States National Association of Insurance Commissioners or similar

Tenant when provided to Landlord; provided, however, that nothing herein
                                  -----------------                     
contained shall limit or impair the right or obligation of Landlord to disclose
such information: (i) to its auditors, attorneys, employees or agents, (ii) when
required by any law, ordinance or governmental order, regulation, rule, policy,
investigation or any regulatory request, (iii) as may be requested or
appropriate in any report, statement or testimony submitted to any municipal,

jurisdiction over Landlord, or to the United States National Association of
Insurance Commissioners, the National Association of Securities Dealers or
similar organizations or their successors, (iv) as may be requested in any
report, statement or testimony provided or submitted to any financial investment
rating service, such as Standard & Poor's Corporation or Moody's Investment

any proceeding, case or matter pending

                                      -30-

understood and agreed that any such assignee shall itself be bound by the terms
and provisions hereof).

    19.       Permitted Contests.  Tenant shall not be required to (i) pay any
              ------------------                                              
Imposition (as hereinafter defined); (ii) comply with any statute, law, rule,
order, regulation or ordinance; (iii) discharge or remove any lien, encumbrance

make any changes to take any action with respect to any encroachment, hindrance,
obstruction, violation or impairment referred to in subsection 10(b), so long as
Tenant shall contest, in good faith and at its expense, the existence, the
amount or the validity thereof, the amount of the damages caused thereby, or the
extent of its liability therefor, by appropriate proceedings during the pendency
of which there is prevented (A) the collection of, or other realization upon,
the tax, assessment, levy, fee, rent or charge or lien, encumbrance or charge so
contested; (B) the sale, forfeiture or loss of the Premises, or any part
thereof, or the Basic Rent or any Additional Rent, or any portion thereof; (C)
any interference with the use or occupancy of the Premises or any part thereof;
and (D) any interference with the payment of the Basic Rent or any Additional
Rent, or any portion thereof.  While any such proceedings are pending, Landlord
shall not have the right to pay, remove or cause to be discharged the tax,
assessment, levy, fee, rent or charge or lien, encumbrance or charge thereby
being contested.  Tenant further agrees that each such contest shall be promptly
prosecuted to a final conclusion.  Tenant shall pay, indemnify and save Landlord
and Permitted Beneficiary harmless against, any and all losses, judgments,
decrees and costs (including all attorneys' fees, appearance costs and expenses)
in connection with any such contest and shall, promptly after the final
settlement, compromise or determination of such contest, fully pay and discharge
the amounts which shall be levied, assessed, charged or imposed or be determined
to be payable therein or in connection therewith, together will all penalties,
fines, interests, costs and expenses thereof or in connection therewith, and
perform all acts, the performance of which shall be ordered or decreed as a
result thereof; provided, however, that nothing herein contained shall be
construed to (a) require Tenant to pay or discharge any lien, encumbrance or
other charge created by any act or failure to act of Landlord or the payment of
which by Tenant is not otherwise required hereunder, or (b) apply in any respect
to the Previous Construction or the Renovations.  No such contest shall subject
Landlord or any Permitted Beneficiary to the risk of any criminal liability.
Tenant shall give such reasonable security to Landlord or such Permitted
Beneficiary as may be demanded by Landlord or such Permitted Beneficiary to
insure compliance with the foregoing provision of this Section 19.

        of preventing Tenant from complying with the terms of this Lease), shall

        winding-up or adjustment of debts (hereinafter collectively called
        "Bankruptcy Law") or if Tenant shall (A) apply for or consent to the
        appointment of, or the taking of possession by, any receiver, custodian,

        against Tenant shall be entered pursuant to any other Bankruptcy Law, or
        if a petition commencing an involuntary case against Tenant or proposing

        if a proceeding or case shall be commenced in any court of competent
        jurisdiction seeking (A) the liquidation, reorganization, dissolution,
        winding-up or adjustment of debts of Tenant or (B) the appointment of a
        receiver, custodian, trustee, United States Trustee or liquidator (or

        or of any substantial portion of Tenant's property, or (C) any similar
        relief as to Tenant pursuant to any Bankruptcy Law, and any such
        proceeding or case shall continue undismissed, or an order, judgement or

        however, that if any notice and/or grace periods are specifically
        provided for any of such defaults by the terms of any of such documents,
        such default shall not constitute an Event of Default under this Lease
        until such default continues uncured beyond any such notice and/or grace
        periods as may be specifically provided therefor in such document, and
        provided further, that no notice or grace periods provided for in this
        Lease shall apply to any such defaults under any of such other
        documents; or

 (vii)  if Tenant fails to deliver to Landlord and Permitted Beneficiary, no
        sooner than 150 days after completion of the Previous Construction, any

(b)    If an Event of Default shall have happened and be continuing, Landlord
       shall have, in its sole discretion, the following rights:

   (i) To give Tenant written notice of Landlord's intention to terminate the
       Term of this Lease on a date specified in such notice. Thereupon, the
       Term of this Lease and the estate hereby granted shall terminate on such
       date as completely and with the same effect as if such date were the date
       fixed herein for the expiration of the Term of this Lease, and all rights
       of Tenant hereunder shall terminate, but Tenant shall remain liable as
       provided herein.

  (ii) To (A) re-enter and repossess the Premises or any part thereof by force,
       summary proceedings, ejections or otherwise and (B) remove all persons
       and property therefrom, whether or not the Lease has been terminated
       pursuant to subsection 20(b)(i) above, Tenant hereby expressly waiving
       any and all notices to quit, cure or vacate provided by current or any
       future law. Landlord shall have no liability by reason of any such re-
       entry, repossession or removal. No such re-entry or taking of possession
       of the Premises by Landlord shall be construed as an election on
       Landlord's part to terminate this Lease unless a written notice of such
       intention be given to Tenant pursuant to subsection 20(b)(i) above.

 (iii) To (but shall be under no obligation to) relet the Premises or any part
       thereof for the account of Tenant, in the name of Tenant or Landlord or
       otherwise, without notice to Tenant, for such term or terms (which may be
       greater or less than the period which would otherwise have constituted
       the balance of the term of this Lease) and on such conditions (which may
       include concessions or free rent) and for such uses Landlord, in its
       absolute discretion, may determine. Landlord may collect and receive any
       rents payable by reason of such reletting. Landlord shall not be
       responsible or liable for any failure to relet the Premises or any part
       thereof or for any failure to collect any rent due upon any such
       reletting.

  (iv) To recover from Tenant, and Tenant shall pay to Landlord on demand, as
       and for liquidated and agreed final damages, and not as a penalty, for
       Tenant's

                                      -34-
<PAGE>
 
       default, and in lieu of all current damages beyond the date of such
       demand, an amount determined in accordance with Exhibit F, it being
                                                       ---------
       acknowledged and agreed by both Landlord and Tenant that during the
       continuation of any Event of Default, an amount determined in accordance
       with Exhibit F shall be fair and appropriate, and payable as liquidated
            ---------
       damages, and not as a penalty, and is an amount which is discounted to
       present net value. If any law shall limit the amount of such liquidated
       final damages to less than the amount above agreed upon, Landlord shall
       be entitled to the maximum amount allowable under such statute or rule of
       law.

   (v) To accept Tenant's irrevocable Purchase Offer which Tenant shall be
       conclusively presumed to have made upon the occurrence of an Event of
       Default. The Purchase Offer shall be deemed to contain an immediate
       closing date and the purchase shall be governed by the terms and
       conditions set forth in subsections 15(b), 15(c), 15(d) and 15(e) of this
       Lease.

  (vi) To continue this Lease in effect for so long as Landlord does not
       terminate Tenant's right to possession of the Premises and Landlord may
       enforce all of its rights and remedies hereunder including without
       limitation the right to recover all Basic Rent, Additional Rent and other
       sums payable hereunder as the same become due.

 (c)   No termination of this Lease pursuant to subsection 20(b)(i), or by
operation of law or otherwise, and no repossession of the Premises or any part
thereof pursuant to subsection 20(b)(ii) or otherwise, and no reletting of the
Premises or any part thereof pursuant to subsection 20(b)(iii), shall relieve
Tenant of its liabilities and obligations hereunder, all of which shall survive
such expiration, termination, repossession or reletting.

 (d)   Notwithstanding anything in this Section 20 to the contrary, Landlord
agrees that Landlord shall pursue the remedy described above in subsection
(b)(iv) only after Landlord has pursued and been denied the remedy described
above in subsection (b)(v).

 21.   Additional Rights of Landlord.
       ----------------------------- 

 (a)   No right or remedy herein conferred upon or reserved to Landlord is
intended to be exclusive of any other right or remedy, and each and every right
and remedy shall be cumulative and in addition to any other right or remedy
given hereunder or now or hereafter existing at law or in equity or by statute.
The failure of Landlord to insist at any time upon the strict performance of any
covenant or agreement or to exercise any option, right, power or remedy
contained in this Lease shall not be construed as a waiver or a relinquishment
thereof for the future. A receipt by Landlord of any Basic Rent, any Additional
Rent or any other sum payable hereunder with knowledge of the breach of any
covenant or agreement contained in this Lease shall not be deemed a waiver of
such breach, and no waiver by Landlord of any

                                      -35-
<PAGE>
 
provision of this Lease shall be deemed to have been made unless expressed in
writing and signed by Landlord.  In addition to other remedies provided in this
Lease, Landlord shall be entitled, to the extent permitted by applicable law, to
injunctive relief in case of the violation, or attempted or threatened
violation, of any of the covenants, agreements, conditions or provisions of this
Lease, or to decree compelling performance of any of the covenants, agreements,
conditions or provisions of this Lease, or to any other remedy allowed to
Landlord at law or in equity.

    (b)    Tenant hereby waives and surrenders for itself and all those claiming
under it, including creditors of all kinds, (i) any right or privilege which it
or any of them may have under any present or future constitution, statute or
rule of law to redeem the Premises or to have a continuance of this Lease for
the term hereby demigod after termination of Tenant's right of occupancy by
order or judgment of any court or by any legal process or writ, or under the
terms of this Lease or after the termination of the term of this Lease as herein
provided, and (ii) the benefits of any present or future constitution, statute

          be calculated as follows:

          (i)   Determine the "Reinvestment Yield." The Reinvestment Yield will
                be determined in the following manner: (A) Landlord will select
                a U.S. Treasury Bond, Note or Bill which Landlord deems to be
                appropriate and which matures or is repayable as close as
                possible to October 15, 2010, (B) the yield for the Treasury
                Bond, Note or Bill selected as described in (A) above will be as
                published two weeks prior to the date of the termination of this
                Lease, (C) the yield determined in (B) above is to be converted
                to an equivalent monthly nominal yield, (D) the monthly nominal
                yield determined in (C) above shall be adjusted to an after tax
                yield by multiplying said yield by 1 minus .34. If there has
                been a tax rate change due to Federal Tax Law Changes as defined
                on Exhibit C, the yield will be by 1 minus the new rate due to
                   ---------
                Federal Tax Law Changes. The yield resulting in (D) is the
                Reinvestment Yield.

          (ii)  Calculate the "Present Value of the Leased Premises." The
                Present Value of the Leased Premises is the present value of the
                original after-tax cash flows anticipated by Landlord from this
                Lease and the Premises, assuming a sale of the Premises on
                October 15, 2010, only modified by Rent Adjustments as provided
                for in Section 5, discounted at the Reinvestment Yield.

          (iii) Determine the applicable equity investment balance as it is
                shown or would be shown on Landlord's financial statements if
                accounted for under GAP, utilizing the original assumptions used
                by Landlord for the

                                      -40-
<PAGE>
 
          purchase of the Premises and modified only by Rent Adjustments as
          provided for in Section 5. Then, subtract the amount of the equity
          investment balance from the Present Value of the Leased Premises as of
          the date of Lease termination. Any resulting positive differential
          shall be divided by 1 minus .34. If there has been a tax rate change
          due to Federal Tax Law Changes as defined on Exhibit C, the positive
          differential will be divided by 1 minus the new rate due to the-
          Federal Tax Law Changes. Any positive quotient that results shall be
          the Lease Make-Whole Premium.

 (i)  The term "Loan Make-Whole Premium" means:
