ITEM 1.  BUSINESS
 
GENERAL
 
     Primark Corporation and its subsidiaries (the "Company" or "Primark") is a
Michigan corporation organized in 1981 engaged in the information services
industry. The businesses consist of the operations of Baseline Financial
Services, Inc. ("Baseline"), Datastream International Limited and affiliates
("Datastream"), Disclosure Incorporated ("Disclosure"), Groupe DAFSA S.A.
("DAFSA"), I/B/E/S International, Inc. ("I/B/E/S"), ICV Limited, ("ICV"), Vestek
Systems, Inc. ("Vestek"), WEFA Holdings, Inc. ("WEFA"), Yankee Group Research,
Inc. (the "Yankee Group") and an 80% investment in Worldscope/Disclosure LLC
("Worldscope"). Primark also has an equity interest in Primark Decision
Economics ("PDE"). Primark develops and markets "value-added" databases that it
combines with proprietary analytical software to create a series of products
used for the analysis and presentation of financial, economic and market
research information. Customers include investment managers, investment bankers,
financial market traders, analysts, accounting and legal professionals,
corporate managers, government officials and information and reference service
providers.
 
     Commencing in 1991, the Company embarked on a strategy of combining
proprietary data content within technologically advanced applications to serve
the increasing information requirements of its customers with value-added
products. In connection with that strategy, the Company acquired Datastream in
1992 and Vestek in 1994, while divesting certain of its non-core operations. In
1995, Primark expanded its domestic presence in information services through the
acquisition of Disclosure and I/B/E/S. In 1996 and 1997, the Company continued
to expand its information business by pursuing a strategy of focusing the
Company's operations solely on its information services businesses. In
connection with that strategy, the Company discontinued its operating segment of
applied technology which was previously recorded as part of the information
services industry segment, as well as its transportation services industry
segment, and its financial services industry segment. During 1996, Primark
acquired DAFSA, ICV, Yankee, a controlling interest in Worldscope and formed a
joint venture, PDE. During 1997, Primark acquired Baseline and WEFA.
 
     Information regarding the revenues, operating results and identifiable
assets of the Company and its subsidiaries, by geographical region, is
incorporated by reference herein from Note 12 to the Consolidated Financial
Statements entitled "Segment and Geographic Information" in the Company's 1997
Annual Report.
 
  Acquisitions
 
     On January 6, 1997, the Company purchased all of the outstanding stock of
Baseline for $41.0 million in cash. Baseline provides institutional investors
with valuation graphics that portray financial market information to customer
accounts throughout the U.S. and Canada.
 
     On February 7, 1997, the Company acquired all of the outstanding stock of
WEFA Holdings, Inc. ("WEFA") for $45.0 million in cash. WEFA is an international
provider of value-added economic information, software and consulting services
to Fortune 500 companies, governments, universities and financial institutions.
 
     Information regarding the Company's acquisitions is incorporated by
reference herein from Note 2 to the Consolidated Financial Statements entitled
"Acquisitions" in the 1997 Annual Report.
 
  Discontinued Operations
 
     In June 1997, the Company adopted a formal plan to sell its transportation
services segment consisting of Triad International Maintenance Corporation
("TIMCO"). The Company anticipates that the sale of TIMCO will be completed by
June 30, 1998. On December 8, 1997, the Company entered into a stock purchase
agreement to sell its subsidiary, TASC and certain of its affiliates, subject to
shareholder approval. On March 30, 1998, the shareholders of Primark approved
the terms of this agreement. The results of both
<PAGE>   4
 
TASC and TIMCO's operations have been reported as a component of discontinued
operations. Prior year consolidated financial statements have been restated to
present these businesses, as well as Primark Storage Leasing Company which was
sold in 1996, as discontinued operations.
 
     Information regarding the Company's discontinued operations is incorporated
herein from Note 3 to the Consolidated Financial Statements entitled
"Discontinued Operations and Dispositions" in the 1997 Annual Report.
 
BUSINESSES AND PRODUCTS
 
DATASTREAM/ICV
 
  Datastream
 
     Datastream provides global historical economic and financial information to
customers worldwide and through its division, Primark Investment Management
Services, Limited, is a leading provider of computer-based accounting and other
investment fund services in the United Kingdom.
 
     The core of Datastream's products is its centralized data system which
maintains a series of linked databases of extensive international economic and
financial data collected from wire services, official publications of national
agencies, stock, options and futures exchanges, other information vendors,
brokers, dealers, banks and issuers. Customers have online access to
Datastream's databases through personal computers, networks or workstations.
Datastream's products and services enable customers to perform extensive
investment research and analysis, investment administration and portfolio
valuations on securities in all major markets, and to produce graphics,
statistics, time series analysis and perform other analytical functions.
Datastream's products and services fall into two principal categories -
investment research and fund management services.
 
     Investment research services accounted for approximately 85% of
Datastream's total revenues for each of the fiscal years ended December 31,
1997, 1996, and November 30, 1995, respectively. These services consist of a set
of software programs to manipulate, analyze and present financial and economic
information obtained from Datastream's databases. The software is designed to
facilitate the customers' access to data from any of Datastream's databases and
to manipulate this data in a variety of pre-programmed and pre-formatted ways
such as graphs, regressions, and tables.
 
     Fund management services accounted for approximately 15% of Datastream's
total revenues for each of the fiscal years ended December 31, 1997, 1996 and
November 30, 1995, respectively. Fund management services, available through
Primark Investment Management Services (PIMS), provide investment accounting,
portfolio valuation and performance measurement activities.
 
     A critical component of Datastream's business is the data itself.
Datastream's principal supply requirements are for raw financial data, which are
acquired from numerous data suppliers worldwide and developed internally. Once
acquired, the data sets are edited and stored in Datastream's databases for
access and manipulation through Datastream's applications and value-added
software programs. Data suppliers generally retain ownership of the raw data,
but allow Datastream and its customers the use of such data. Datastream places
great importance on the quality of its data and has developed a program to
continuously review its data sources to ensure quality, control and continuity.
Wherever possible, Datastream develops multiple sources of data to provide
backup and cross checking.
 
     Data relating to equities include pricing information for earnings and
dividends on approximately 50,000 stocks from 64 countries, including all major
markets and a number of emerging markets. This data includes historical earnings
and dividend data, as well as forecast data supplied by market specialists. Data
relating to bonds include maturity and yield on approximately 83,000 corporate
and government bonds from 32 countries, all Eurobonds and related indices. Data
relating to futures and options includes current prices, previously traded
prices, trading volume and intra-day high and low values from the international
options and futures exchanges, including LIFFE (London), MONEP and MATIF
(Paris), SOFFEX (Switzerland), EOE (Amsterdam), DTB (Germany), Chicago and
Philadelphia.
 
                                        2
<PAGE>   5
 
     Datastream has included databases from I/B/E/S, Disclosure and Worldscope
as an integral part of its investment research services. Consequently, it has
helped these companies gain additional customers, as well as customers new to
Datastream. Datastream has also installed the full Disclosure index on its
online system and offers index searches and electronic ordering of hard copy
documents to Datastream users. Vestek is also developing investment management
software products that will be marketed and supported by Datastream's European
sales and service personnel.
 
  ICV
 
     ICV provides real-time on-line prices, news and research on the U.K.
equities market as well as systems for order entry and trade reporting. The
company's software combines real-time prices with news and other data in a
unique format which has become the standard presentation for U.K. equity data.
ICV has incorporated Datastream's historical information as an add on to its
major product, TOPIC, and is continuing to integrate both Primark Company data
and third party data into its major products.
 
     The core of ICV products is its central systems that take real-time data
from several exchanges and combine the prices with news. The information is then
broadcast to a customer base of nearly 9,000 terminals using the datacast
bandwidth on terrestrial television, leased telecommunication circuits or via
satellite. The data is broadcast to customers' systems, provided by ICV, where
the signal is decoded, stored on a local database and presented on user screens
utilizing software designed and maintained by ICV. Timeliness and reliability
are critical aspects of ICV's services. ICV's central systems are designed to
provide state-of-the-art timeliness by handling incoming data within a few
milliseconds by utilizing program code that resides in memory. Reliability is
provided through several back-up sites. The investment in trading systems has
allowed for the set up of a U.K. wide interactive network which can be used to
link customers' offices and provide a future conduit to any new data sources ICV
may acquire or develop in the future. ICV's two principal products are TOPIC and
MARKET-EYE.
 
     TOPIC services accounted for 53%, 47%, and 45% of ICV's total revenue for
the fiscal years ended December 31, 1997, 1996 and 1995, respectively. TOPIC
services provide real-time data on prices and comparative quotes from market
makers with historical charts and research from brokers. During 1997, the London
Stock Exchange moved to an order driven market. In connection with this event,
ICV was able to meet its customers' requirements for an interactive trade
reporting system through its TOPIC product. The TOPIC services are used by
traders and fund managers, stockbrokers, U.K. clearing banks and major publicly
traded corporations.
 
     MARKET-EYE services accounted for 12%, 11% and 11% of ICV's revenue for the
fiscal years ended December 31, 1997, 1996 and 1995 respectively. MARKET-EYE is
aimed predominantly at the private investor and is accessable via the Internet.
The data include prices and news and may be combined with analytical and
charting packages supplied by third parties.
 
     Stock exchange fees accounted for 29%, 35% and 36% of ICV's revenues for
the fiscal years ended December 31, 1997, 1996, and 1995, respectively. Exchange
fees are revenues collected by ICV and remitted to the Stock Exchanges to permit
customer use of exchange data feeds. Consequently, the exchange fee business is
a low margin business.
 
     ICV has leveraged its existing technology through alliances with other
information companies, providing access to new markets. During 1996, ICV entered
a joint venture with Merrill Lynch to leverage its technology with Merrill
Lynch's expertise in live trading systems. Also during 1996, Primark entered a
joint venture with Dow Jones & Company, Inc. and its subsidiary Dow Jones
Markets to develop an international equity trading information product by
combining ICV's technology, Datastream's historical databases, the global news
capability of Dow Jones and the real time data capability of Dow Jones Markets.
 
     On March 17, 1998, Dow Jones & Company Inc. reported that it has agreed to
sell its wholly owned subsidiary, Dow Jones Markets to Bridge Information
Systems, Inc. While Dow Jones & Company and Dow Jones Markets are both
contractually obligated to provide news and financial information for the
Primark/Dow Jones product, this business relationship is under review and may be
continued, altered or terminated.

DISCLOSURE/WORLDSCOPE
 
     Disclosure is a leading provider of "as reported" and abstracted financial
information in the U.S. market, distributing information on over 16,000 U.S.
companies and 13,000 foreign companies, derived from a variety of government and
third-party sources. Disclosure's proprietary content is provided on a
subscription and per use basis through electronic media such as online services
and compact laser discs, as well as through printed products.
 
     Disclosure's financial information products and services are based upon a
wide spectrum of Securities and Exchange Commission ("SEC") documents such as
Forms 10-K and 10-Q, proxy statements, registration statements and material
event reports, and increasingly non-SEC documents such as foreign company
financial filings, news, economic data, pricing information and U.S. and foreign
annual reports. The information included in Disclosure's products is obtained
through contractual relationships with the SEC and major stock exchanges, from
other Primark Companies and through commercial acquisition of the information.
Once acquired, Disclosure indexes, tags, abstracts and formats the information
to allow for ease in navigation, searches and analysis.
 
     Primark considers Disclosure's electronic media business, comprised of
Global Access, Worldscope, compact discs and revenues from third party
distributors of its value-added database products, as representing Disclosure's
next generation of product offerings. These products represented approximately
40% of Disclosure's overall revenues at the end of 1997, up from 20% in 1996.
 
     Disclosure's image-based services are delivered through the Global Access
and Laser D products as well as through Info Centers. Global Access is a
web-based front end that offers online and real-time access to Disclosure's
proprietary electronic index of public company documents; online delivery of
Disclosure's value-added EDGAR database; access to over ten years of data on
29,000 companies in the Worldscope and SEC databases; institutional and
corporate ownership data; and links to third-party content such as I/B/E/S and
industry news. Global Access provides real-time broadcast alert functionality as
well as desktop full text and field searching and screening of company and
industry information with direct downloading to spreadsheets and word
processors. Laser D is a multi-disc CD-ROM document database that provides a
desktop library of information to high volume document users who require instant
access to documents filed with the SEC, banking agencies and U.S. and foreign
stock exchanges. The Info Centers are staffed by research specialists who assist
customers in locating requested information and produce alert services for
customers who want early identification of specified documents. Approximately
82%, 81% and 81% of Disclosure's total revenues were derived from document
services for the twelve months ended December 31, 1997, 1996, and 1995,
respectively.
 
     Disclosure's database segment provides products that can be machine read
and manipulated by the end users. Disclosure's Global Researcher and Compact D
products provide access to perform sophisticated searching of financial and text
information on over 29,000 companies. These products also provide reporting and
graphing functionality. Proprietary Disclosure databases include EdgarPlus (SEC
filings with value-added navigational and style tags), the SEC 34 Act database
(over 11,000 U.S. Company profiles and financial statement abstracts dating back
over 10 years) and other databases on institutional and corporate insider
transactions. These proprietary databases are offered by third-party vendors
which target both the commercial and consumer markets, enhancing Disclosure's
product through their hardware, software, and market focus. Such vendors include
Bridge, Dow Jones, Factset, Lexis, MAID, UMI and West. Approximately 18%, 19%
and 19% of Disclosure's total revenues were derived from database services for
the years ended December 31, 1997, 1996 and 1995, respectively.
 
     Worldscope contains a collection of descriptive profiles and standardized
financial statements on over 11,900 companies in 45 countries. The Worldscope
database is standardized, indexed and organized for cross-border screening and
searching. In addition to its global database, Worldscope offers an emerging
market database. Worldscope products are delivered via third-party distributors,
CD-ROM and online platforms. In October 1996, Primark acquired an additional 30%
ownership in Worldscope, giving Primark an 80% controlling interest.

YANKEE GROUP RESEARCH, INC.
 
     The Yankee Group consists of a global team of highly skilled technology and
market experts that focuses on identifying current trends and future directions
in the communications and computer industries for business and consumer markets.
The company markets these insights by providing strategic planning, technology
forecasting, consulting and market research to clients worldwide, including
vendors and users of major computer and communications systems and services. The
Yankee Group's products and services fall into three principal
categories -- Planning Services, Custom Consulting Engagements, and Seminars and
Conferences.
 
     Planning Services accounted for 66% and 71% of the total revenues for the
years ended December 31, 1997 and 1996, respectively. An annually renewable
Planning Service subscription provides a customer with consultation time with a
research analyst, quarterly audio conferences, access to the Yankee Group's
published research reports and whitepapers in both an electronic and paper
format, and discounts on seminars. The Yankee Group currently offers 24 Planning
Service packages.
 
     Custom Consulting Engagements accounted for 20% and 20% of the total
revenues for the years ended December 31, 1997 and 1996, respectively. Custom
Consulting Engagements often result from an extension of Planning Services when
an inquiry or a study is more extensive than that offered through a Planning
Service subscription. Custom Consulting contracts are also entered into with
external parties where the company considers the study to be of strategic
importance.
 
     Seminars and Conferences accounted for 14% and 12% of the company's total
revenues for the years ended December 31, 1997 and 1996, respectively. The
Yankee Group holds an average of fifteen to twenty seminars and/or conferences a
year, often in conjunction with industry publication houses.

MARKETING
 
     The products and services of Primark's information companies are marketed
worldwide. Increasingly, the individual Primark companies are offering each
other's data through their own delivery platforms.
 
     Datastream is located in London, England and has sales and support offices
located in Germany, France, Italy, Spain, Switzerland, the Netherlands, Belgium,
Luxembourg, Sweden, Japan, Hong Kong, Singapore, Australia, Korea, Thailand,
Canada and the United States. ICV is located in London, England and has sales
and support offices throughout the U.K. Datastream/ICV sells both Disclosure and
I/B/E/S data through their platforms.
 
     Disclosure and Worldscope market and distribute their products
predominately in the United States. In addition to employing a domestic and
international sales force, Disclosure extends its sales and marketing reach with
Info Centers strategically located in the major financial centers including ten
major U.S. cities and several international locations including London,
Frankfurt, Madrid, Paris, Milan, Hong Kong, Mexico City and Tokyo. Disclosure
also incorporates I/B/E/S data and WEFA data in its Global Access Platform.
 
     I/B/E/S, headquartered in New York City with offices in London, Hong Kong
and Tokyo, delivers its products directly to customers via state-of-the-art
electronic delivery media. I/B/E/S Express, the fastest growing delivery
mechanism, is a PC-based proprietary software, database management and
communications package. The I/B/E/S Express platform separately provides

products through a network of more than 30 electronic third-party distributors
including Bloomberg, Bridge, Datastream/ICV, FactSet, FAME, OneSource, Reuters,
S & P Compustat and Vestek. These third-party distributors offer I/B/E/S a
mechanism to reach new markets and link I/B/E/S data to other databases and
applications software.
 
     Baseline's product is targeted primarily toward portfolio managers of
domestic equities and carries portions of Disclosure's data as part of its
product offering. Baseline delivers its product directly to customers via an

<PAGE>   10
 
     WEFA markets its product through its international sales force. WEFA
delivers its data online through I/B/E/S and Disclosure as well as through its
own electronic distribution platform. WEFA believes its historical association
with the Wharton School of Business and with Nobel Laureate Lawrence R. Klein
gives it a distinct advantage in the marketplace.
 
     The Yankee Group markets its services internationally primarily through its
own sales force. The Company considers its historic record of accurately
forecasting the general direction of communication and computing technology
together with its focus on customer support as its greatest competitive
advantages. Yankee's industry analysts are the company's critical resource.
These individuals have significant expertise in their areas of concentration,
gained through industry experience, constant study of the technology market and
ongoing dialogue with vendors and consumers in the industry.
 
COMPETITION
 
     The global information industry is highly competitive. There are many large
and successful companies in the information services industry that supply
financial economic and market research data competitive to products and services
provided by Primark's information businesses. The advancement of electronic
delivery via online vendors and the Internet has further impacted the
competitive environment in the information market.
 
     Principal competitive factors include the quality, reliability and
comprehensiveness of the analytical services and data provided, flexibility in
tailoring services to client needs, experience, innovation, the capability of
technical and client service personnel, data processing and decision support
software, reputation, price and geographic coverage. Primark distinguishes its
products through its broad international coverage, wide range of databases,
accuracy of the data, proprietary software applications, reputation, experience
and quality of customer support provided.
 
     Primark's ability to remain competitive in the information market will
depend largely upon its ability to maintain and develop new products and access
new markets in a cost efficient manner, as well as the integration of all its
information products and services. There can be no assurance that Primark will
continue to maintain its market share in the future.
 
TECHNOLOGICAL CHANGES
 
     The Company operates principally in the information services industry which
changes rapidly and is highly competitive. Even if the Company remains abreast
of the latest developments and available technology, technological advances
and/or the introduction of new products and services in the information services
industry could adversely affect the Company. There are many large and successful
companies in the information services industry, many of which have greater
resources than the Company. The Company's future success will depend
significantly on its ability to develop and deliver technologically advanced
quality products and services. The cost of developing such products and services
could adversely affect the Company's future results of operations.
 
     The Company has a formal plan and task force assigned to make all of its
financial systems, product offerings and related databases year 2000 compliant.
In 1997, the Company spent $1.5 million of resources on this endeavor and
anticipates that it will be required to spend an additional $2.7 million and
$2.6 million in 1998 and 1999, respectively, to be year 2000 compliant. The
majority of the remaining year 2000 work will be performed at Datastream/ICV. To
the extent the Company is unable to become fully year 2000 compliant, it may
have a materially adverse effect on the Company.
 
FOREIGN OPERATING RISKS
 
     Since not all of the Company's revenues and expenses incurred are in U.S.
dollars, the Company's operations have been and may continue to be affected by
fluctuations in currency exchange rates. For the year ended 1997, international
revenues and operating income of the Company's Continuing operations represented
56% and 56%, respectively, of total consolidated revenues and operating income.
 
                                        8
<PAGE>   11
 
     Consequently, the Company is exposed to certain risks associated with an
international business, particularly with respect to foreign currency exchange
rate movements. International business is also subject to the customary risks
associated with international transactions, including political risks, local
laws and taxes, the potential imposition of trade or currency exchange
restrictions, tariff increases and difficulties or delays in collecting accounts
receivable. Weak foreign economies and/or a weakening of foreign currencies in
certain countries against the U.S. dollar would adversely affect the Company's
overall future operating results and cash flows.
 
     The Company engages in hedging activities, including foreign currency
options and forward contracts, in order to minimize the ongoing exposure to
foreign currency exchange risk with respect to its foreign operating income and
cash flows. In 1997, the Company recorded a $1.9 million gain before income
taxes for foreign currency transactions. In addition, the Company typically
maintains foreign currency hedges for its significant foreign currency
exposures.
 
TRADEMARKS
 
     Primark's information companies hold numerous trademarks worldwide that are
subject to continuous renewal. These trademarks are significant to the Company's
business, and are registered in all of the Company's major markets to ensure
recognition among its many global trading customers.
 
EMPLOYEES
 
     At December 31, 1997, the Company and its subsidiaries employed 2,328
persons. The Company sponsors a number of employee benefit plans including a
401(k) savings deferral plan and certain foreign defined benefit plans. The
Company believes its relationship with its employees to be satisfactory.

ITEM 3.  LEGAL PROCEEDINGS
 
     On June 24, 1994, a jury in a civil case in Massachusetts Superior Court
(the "Court") returned an unfavorable verdict against the two founders of TASC,
Inc., ("TASC") and against TASC itself. The suit was brought by a former
employee regarding a TASC stock transaction which took place in 1976, prior to
Primark's acquisition of TASC in 1991. The defendants in the Bradley litigation,
the two founders of TASC, have settled the lawsuit for $4,000,000 plus an amount
of up to $8,500,000 that was conditioned on the outcome and reasoning of a
then-pending motion for a directed verdict and a new trial. TASC has been
advised that the founders are disputing with the plaintiff whether any
additional amount is owing under the terms of the settlement, and it appears
that those parties will proceed to arbitration of that dispute. Also, the
founders settled a related claim for $600,000. The founders have demanded that
TASC indemnify them for amounts paid in such settlements, totaling up to $13.1
million, and associated expenses. TASC has advised counsel for the founders that
their settlement agreements do not appear to satisfy by-law requirements
(including prior company approval) and has requested clarification of the basis
for the founders' indemnification claims. Neither Primark, nor any of its
directors or officers, was a party to the Bradley litigation. Assuming the sale
to Litton Industries, Inc. of all of the outstanding common stock of TASC, Inc.
is consummated, Litton has agreed to indemnify and hold harmless, to the fullest
extent permitted by law, Primark and its directors and officers, from and
against all liability and charges resulting from the Bradley litigation.
 
     The Company and its subsidiaries are involved in other administrative
proceedings and matters concerning issues arising in the ordinary course of
business. Management cannot predict the final disposition of such issues, but
believes that adequate provision has been made for the probable losses and the
ultimate resolution of these proceedings will not have a material adverse effect
on the Company's financial condition, results of operations or financial
liquidity.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     On March 30, 1998, the Company held a special meeting of its shareholders
for the purpose of obtaining a vote related to the sale of TASC as described in
the Company's definitive proxy statement dated February 26, 1998. Proxies for
the meeting were solicited pursuant to Section 14(a) of the Securities Exchange
Act of 1934. There was no solicitation in opposition to management's
solicitations.
 
THE SALE OF TASC WAS APPROVED BY THE FOLLOWING VOTE:

                                   RECITALS:

         A. The Borrower has entered into (a) a Revolving Credit Agreement (as

         B. The parties hereto desire to amend further the Credit Facilities as
set forth herein.

         NOW THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

         SECTION 1. AMENDMENTS

         (a) AMENDMENT TO COVENANT RELATING TO MERGERS, ETC. Section 7.08 of
each Credit Facility is hereby amended by deleting clause (a) thereof and
replacing it with the following new clause (a):

         (a) A Subsidiary of the Borrower may (i) merge with or into or
     consolidate with, or liquidate or dissolve into, any other Subsidiary of
     the Borrower, or (ii) merge into, or liquidate or dissolve into, the
     Borrower, provided that the surviving entity is the Borrower, or (iii) in
     the case of a Wholly Owned Subsidiary of the Borrower, acquire a
     substantial portion of the properties of the Borrower, or acquire all or a
     substantial portion of the properties of any other Subsidiary of the
     Borrower, or (iv) in the case of a Wholly Owned Subsidiary of the Borrower,
     acquire from the Borrower or any other Subsidiary of the Borrower any
     Shares of Capital Stock or other equity interest owned by the Borrower or
     such other Subsidiary (it being understood that, subject to the other
     provisions of the Loan Documents, in the event that a wholly Owned
     Subsidiary thus acquires from the Borrower Shares of Capital Stock which
     constitute Collateral Agent to release such Shares of Capital Stock from
     the Lien in favor of the Collateral Agent); and

         (b) AMENDMENT RELATING TO OPTIONAL PREPAYMENTS UNDER THE NOTE BACKUP
AGREEMENT. Section 3.12 of the Note Backup Agreement is hereby amended by

its sole



<PAGE>   2
discretion from time to time), any such prepayment may be made in a principal
amount other than a principal amount permitted under Section 3.11.

     Section 2. Effectiveness and Effect, etc.

     (a) Effectiveness.  This Amendment shall become effective, with effect as
of the date hereof, when Mellon Bank, N.A., as Agent under each Credit
Facility, shall have received counterparts hereof duly executed by the Borrower
and by the "Required Lenders" and the "Agent" under each Credit Facility.

     (b) Effect.  The Revolving Credit Agreement, the Term Loan Agreement and
the Note Backup Agreement, as amended by the letter agreement dated February
21, 1997, the Amendment to Transaction Documents dated as of May 1, 1997 and
the Amendment to Transaction Documents dated as of June 30, 1997, and as
further amended hereby, are and shall continue to be in full force and effect
and are hereby in all respects ratified and confirmed.  Except to the extent
expressly set forth herein, the execution, delivery and effectiveness of this
Amendment shall not operate as a waiver of any right, power or remedy under any
Credit Facility or constitute a waiver of any provision of any Credit Facility.

     Section 3. Miscellaneous.  This Amendment may be executed in any number of
counterparts and by the different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed to be an original and
all of which taken together shall constitute but one and the same document.
Section and other headings herein are for reference purposes only and shall not
affect the interpretation of this Amendment in any respect.  This Amendment
shall be governed by and construed in accordance with the laws of the
Commonwealth of Pennsylvania, without regard to choice of law rules. This
Amendment is a requested amendment within the meaning of Section 10.06(a) of
each Credit Facility. 

     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be

                                    RECITALS:

                  A. The Borrower has entered into (a) a Revolving Credit
Agreement (as amended, the "Revolving Credit Agreement") dated as of February 7,
1997 among Primark Corporation (the "Borrower"), the Lenders parties thereto
from time to time, the Issuing Banks referred to therein, and Mellon Bank, N.A.,

                  B. The parties hereto desire to amend further the Credit

referred to in each of the Credit Facilities (the "Collateral Agency Agreement")
and the Borrower Pledge Agreement referred to in the Collateral Agency Agreement

                  NOW THEREFORE, the parties hereto, intending to be legally
bound, hereby agree as follows:

SECTION 1.  CERTAIN AMENDMENTS TO THE FINANCIAL TERMS OF THE REVOLVING CREDIT 
            AGREEMENT.

(a)  Revolving Credit Agreement, Section 2.01(a), is amended to read as follows:

                  (a) REVOLVING CREDIT COMMITMENTS. Subject to the terms and
         conditions and relying upon the representations and warranties herein
         set forth, each Lender, severally and not jointly, agrees (such
         agreement being herein called such Lender's "Revolving Credit
         Commitment") to make loans (the "Revolving Credit Loans") to the
         Borrower at any time or from time to time on or after the date hereof
         and to but not including the Revolving Credit Maturity Date. A Lender
         shall have no obligation to make any Revolving Credit Loan to the
         extent that such Lender's Revolving Credit Exposure at any time would
         exceed such Lender's Revolving Credit Committed Amount at such time.
         Each Lender's "Revolving Credit Committed Amount" at any time shall be
         equal to the amount set forth as its "Initial Revolving Credit
         Committed Amount" below its name on the signature pages hereof, as such
         amount may have been reduced under Section 2.01(f) hereof at such time,
         and subject to transfer to another Lender as provided in 
<PAGE>   2
         Section 10.14 hereof; provided, that upon the occurrence of the
         Extension Date, each Lender's "Revolving Credit Committed Amount shall
         be automatically increased by an amount equal to such Lender's Pro Rata
         share of $150,000,000. The sum of the Revolving Credit Committed
         Amounts of the Lenders shall not exceed $75,000,000 at any time before
         the Extension Date or $225,000,000 at any time on or after the
         Extension Date.

(b) Revolving Credit Agreement, Section 2.01(c), is amended by deleting the
period at the end thereof and replacing it with the following: "; provided, that
Revolving Credit Notes issued pursuant to Section 5.03 in connection with the
Extension Date shall be dated the Extension Date and shall be in the face amount
equal to such Lender's Revolving Credit Committed Amount on the Extension Date
after giving effect to the increase in the Revolving Credit Committed Amounts on
such date."

(c) Revolving Credit Agreement, Section 2.01(e), is amended by adding the
following line (ignoring the caption, which is set forth below only for
reference purposes):

     If the Applicable Margin for                 Then the Revolving Credit
     such day is to be determined                 Commitment Fee Percentage for
     in accordance with                           such day is
     ------------------                           -----------

     Level V Performance Margins                          0.20%


(d)  The following new Sections 2.01(g) and 2.01(h) are added to the Revolving 
     Credit Agreement:

                  (g) AUTOMATIC REDUCTION OF THE REVOLVING CREDIT COMMITTED
         AMOUNTS. The aggregate Revolving Credit Committed Amounts of the
         Lenders shall be reduced automatically by the following amounts on the
         following dates:

                  Date of Reduction                      Amount of Reduction
                  -----------------                      -------------------

                  December 31, 1998                              $5,000,000
                  June 30, 1999                                  $5,000,000

         To the extent any such reduction amount exceeds the aggregate Revolving
         Credit Committed Amounts of the Lenders on such date, the excess shall
         be ignored. Each such automatic reduction of the Revolving Credit
         Committed Amounts shall be applied Pro Rata to the Revolving Credit
         Committed Amounts of the Lenders. After the date of such reduction the
         Revolving Credit Commitment Fee shall be calculated upon the Revolving
         Credit Committed Amounts as so reduced.

                  (h)  CERTAIN ADDITIONAL FEES IN CERTAIN CIRCUMSTANCES.

                  (i) In consideration of the Lenders entering into the

         Pro Rata share of $75,000, and (B) to the Agent, for its own account, a

         structuring fee in the amount agreed by the Borrower and the Agent. The
         obligations of the Borrower under this Section 2.01(h)(i) shall survive
         any termination of this Agreement.

                  (ii) In the event that at any time before the first
         anniversary of the effective date of the Agreement dated as of March 6,
         1998 (or, if the Extension Date occurs, at any time before the first
         anniversary of the Extension Date) any of the following events or
         conditions shall have occurred: (A) an event or condition referred to
         in Section 8.01(m) hereof shall have occurred, (B) the Borrower shall
         have consolidated or merged with or into any other Person, (C) the
         Borrower shall have liquidated, commenced a Wind-up, dissolved or

         transferred all or substantially all of its assets to any other Person
         or Person, voluntarily or involuntarily, then, and in any such event
         (whether or not consented to or waived by the Lenders), in addition to
         all other amounts payable under this Agreement and the other Loan
         Documents, the Borrower shall pay to the Agent, for the account of each
         of the Lenders, on the third Business Day following the occurrence of
         such event, a fee equal to such Lender's Pro Rata share of $150,000.
         The obligations of the Borrower under this Section 2.01(h)(ii) shall
         survive any termination of this Agreement.

         less than 2.50, if the last day of such fiscal quarter is on or before
         the Extension Date, or (y) less than 2.50 and greater than or equal

         Test V is satisfied and the other conditions set forth above are met.
         "Financial Test V" means that as of the end of the relevant fiscal
         quarter, the Consolidated Funded Debt Ratio (Adjusted) for the period
         of four consecutive fiscal quarters ending on the last day of such
         fiscal quarter, considered as a single accounting period, is less than
         2.00; provided, that Financial Text V shall not be deemed to be

         Credit Committed Amounts and prepay the Revolving Credit Exposures, and
         any requirement under the Term Loan Agreement to prepay the
         Indebtedness outstanding thereunder) give rise to any "Excess Proceeds"
         as defined in the Senior Note Indenture (taking into account the
         periods specified in the Senior Note Indenture which must elapse before
         amounts constitute "Excess Proceeds") (Recapture Asset Dispositions
         described in this clause (B) being sometimes referred to herein as

                  Collateral Agency Agreement to the Term Loan Agent requesting
                  the Term Loan Agent to give to the Collateral Agent the notice
                  contemplated by Section 2.05(b) of the Collateral Agency

                  request.

         In the event that the Extension Date occurs, the Agent shall promptly
         notify each of the Lenders of such fact and shall promptly distribute
         to each Lender its new Revolving Credit Note. Promptly following its
         receipt of such new Revolving Credit Note, each Lender shall promptly

SECTION 3.  CERTAIN AMENDMENTS TO THE FINANCIAL TERMS OF THE NOTE BACKUP 
            AGREEMENT.

(a) Note Backup Agreement, Section 3.01(c), final sentence, is amended to read
as follows: "The 'Letter of Credit Fee Rate' for any day shall mean the
Applicable Margin applicable under the Euro-Rate Option on such day (whether or
not the Extension Date has occurred and, accordingly, whether or not the
Euro-Rate Option is actually available to the Borrower on such day)."

(b)  Note Backup Agreement, Section 3.04(a), is amended to read as follows:

                  (a) BORROWER'S REIMBURSEMENT OBLIGATION. The Borrower hereby
         agrees to reimburse the Issuing Bank, by making payment to the Agent
         for the account of the Issuing Bank in accordance with Section 3.15(b)
         hereof, in the amount of each Letter of Credit Unreimbursed Draw, which
         reimbursement shall be due at the following times:

                           (x) if the Extension Date has not occurred, on
                  October 16, 2000 (the "Reimbursement Target Date") and
                  thereafter ON DEMAND,

                           (y) if the Extension Date has occurred, ON DEMAND;
                  provided, that if any unpaid amount of any Letter of Credit
                  Unreimbursed Draw is subject to a Euro-Rate Funding Period
                  beginning before the Extension Date and ending after the
                  Extension Date, reimbursement of such unpaid amount shall,
                  subject to the other provisions of this Agreement and the
                  other Loan Documents, be payable on the last day of such
                  Euro-Rate Funding Period.

         Such reimbursement shall also be due at such earlier times as are
         provided elsewhere in this Agreement and the other Loan Documents.

(c)  Note Backup Agreement, Section 3.09(a), is amended to read as follows:

                  (a) INTEREST RATE OPTIONS. Interest on the unpaid amount of
         Letter of Credit Unreimbursed Draws shall bear interest for each day
         until due on one or more bases selected by the Borrower from among the
         interest rate Options set forth below. Subject to the provisions of
         this Agreement, during any period before an unpaid amount of a Letter
         of Credit Unreimbursed Draw is due, such unpaid amount shall bear
         interest at the Base Rate Option, unless and until converted to the
         Euro-Rate Option in accordance with the provisions of this Agreement.
         Subject to the provisions of this Agreement, during any period before
         an unpaid amount of a Letter of Credit Unreimbursed Draw is due, the
         Borrower may select different Options to apply simultaneously to
         different Portions of such unpaid amount and may select different
         Funding Segments to apply simultaneously to different parts of the
         Euro-Rate Portion of such unpaid amount. The interest rate Options
         applicable to unpaid amounts of Letter of Credit Unreimbursed Draws
         before such unpaid amounts become due are as follows:

                         (i) BASE RATE OPTION: A rate per annum (computed on the
                  basis of a year of 365 or 366 days, as the case may be, and
                  actual days elapsed) for each day equal to the Base Rate for
                  such day plus the Applicable Margin for such day.

                         (ii) EURO-RATE OPTION: A rate per annum (based on a
                  year of 360 days and actual days elapsed) for each day equal
                  to the Euro-Rate for such day plus the Applicable Margin for
                  such day.


                                      -6-
<PAGE>   7
         From and after the date reimbursement of any unpaid amount of Letter of
         Credit Unreimbursed Draw is due, such unpaid amount shall bear interest
         in accordance with Section 3.15(c) hereof. For the avoidance of doubt,
         for all purposes of this Agreement and the other Loan Documents, any
         unpaid amount of any Letter of Credit Unreimbursed Draw which is
         payable on demand shall be deemed due, whether or not any demand for
         payment has been made.

(d) Note Backup Agreement, Section 3.09(b), is amended as provided in Section
1(e) of this Amendment. In addition, in the table of Applicable Margins, the
Applicable Margins for the Euro-Rate Options are amended as follows:

         (i) under Level I Performance Margins, "1.25%" is amended to read
         "1.25% or, after the Extension Date, 1.00%",

         (ii) under Level II Performance Margins, "1.00%" is amended to read
         "1.00% or, after the Extension Date, 0.75%",

         (iii) under Level III Performance Margins, "0.875%" is amended to read
         "0.875% or, after the Extension Date, 0.625%", and

         (iv) under Level IV Performance Margins, "0.75%" is amended to read
         "0.75% or, after the Extension Date, 0.50%".

In addition, the following additional paragraph is added following the end of
the table of Performance Margins (after the table entry relating to Level V
Performance Margins):

                  Notwithstanding the foregoing, if the Extension Date has
         occurred and if any unpaid amount of any Letter of Credit Unreimbursed
         Draw is subject to a Euro-Rate Funding Period beginning before the
         Extension Date and ending after the Extension Date, the Applicable
         Margin applicable to calculation of interest on such unpaid amount for
         each day from and after the Extension Date shall not be affected by the
         occurrence of such Extension Date and shall be determined as if the
         Extension Date had not occurred.

(e)  Note Backup Agreement, Section 3.09(c)(ii), is amended to read as follows:

                  (ii) The Borrower may not select a Funding Period that would
         end after the Reimbursement Target Date or, if the Extension Date has
         occurred, after the Extension Date; and

(f) Section 3.12 of the Note Backup Agreement is amended by deleting the final
sentence thereof and replacing it with the following: "Any such prepayment shall
be made in accordance with Section 3.11 hereof; provided, that with the consent
of the Agent (which the Agent may grant or withhold in its sole discretion from
time to time), any such prepayment may be made in a principal amount other than
a principal amount permitted under Section 3.11."

(g) Note Backup Agreement, Annex A, Section 1.01, is amended by adding the
following new definition in its appropriate place in alphabetical order:

         Expenditures for such period. For purposes of determining the

         Capital Expenditures of TASC and its Subsidiaries shall be included for
         each complete fiscal quarter during which TASC is a wholly-owned
         Subsidiary of the Borrower (notwithstanding that the Borrower may have

         a consequence of the proposed TASC Disposition), and (y) on any date on

         EBITDA Less Capital Expenditures of TASC and its Subsidiaries shall be
         excluded for all periods, whether before or after the date on which the
         TASC Disposition occurs.

                               PRIMARK CORPORATION

                              OFFICER'S CERTIFICATE

                  The undersigned, an officer of Primark Corporation, a Michigan
corporation (the "Borrower"), hereby certifies on behalf of the Borrower as
follows:

                  1. This certificate is delivered to Mellon Bank, N.A., as
Agent, pursuant to Section 5.03 of the Revolving Credit Agreement dated as of
February 7, 1997 (as amended, modified or supplemented from time to time, the
"Revolving Credit Agreement") by and among the Borrower, the Lenders from time
to time parties thereto, the Issuing Banks referred to therein, and Mellon Bank,
N.A., as Agent. Capitalized terms used herein and not otherwise defined have the
meanings as ascribed to them in the Revolving Credit Agreement.

                  2. The Borrower desires the Extension Date to occur on the
date of this certificate.

                  3. On the date hereof, all of the conditions set forth in
Section 5.03 of the Credit Agreement have been satisfied. Without limiting the
generality of the foregoing:

                  (a)  The TASC Disposition occurred on ___________, 1998.

                  (b) The Borrower has given notice to the trustee under the
         Senior Note Indenture of redemption of all of the outstanding Senior
         Notes, specifying as the "Redemption Date" a date not later than 60
         days after the TASC Disposition.

                  (c) The Borrower has indefeasibly paid in full in cash all
         Term Loan Obligations (other than Contingent Indemnification
         Obligations), as such terms are defined in the Collateral Agency
         Agreement. Such payment was made on the date of this certificate. The
         Borrower has given a written notice pursuant to the final sentence of
         Section 2.05 of the Collateral Agency Agreement to the Term Loan Agent
         requesting the Term Loan Agent to give to the Collateral Agent the
         notice contemplated by Section 2.05(b) of the Collateral Agency
         Agreement.

                  (d) No Event of Default or Potential Default has occurred and
         is continuing or exists on the date hereof or will occur or exist after
         giving effect to the Extension Date. The aggregate Revolving Credit
         Committed Amounts of the Lenders on the date hereof, before giving
         effect to the increase in the Revolving Credit Committed Amounts
         occurring on the Extension Date, is not less than $75,000,000.

                  Executed this_______________day of_________________, 1998.

         amended by the Cumulative Amendment (the "Replacement Revolving Credit

                  In my examination I have assumed the genuineness of all
signatures (other than those on behalf of the Borrower), the legal capacity of

the conformity to original documents of all documents submitted to me as
certified or photostatic copies and the authenticity of the originals of such

independently establish or verify, I have relied upon the statements and
representations of officers and other representatives of the Borrower and of
public officials.

                  I am admitted to the Bar of the State of Michigan, and I do
not express any opinion as to the laws of any jurisdiction other than the State
of Michigan and the federal laws of the United States of America.

                  The opinions set forth below are subject to the following
qualifications:

                           (a) enforcement of the Specified Documents may be
                  limited by applicable bankruptcy, insolvency, fraudulent
                  transfer, reorganization, moratorium or other similar laws
                  affecting creditors' rights generally and by general
                  principles of equity (regardless of whether enforcement is
                  sought in equity or at law);

                           (b) certain of the remedial provisions including
                  waivers, with respect to the exercise of remedies against the
                  collateral contained in the Borrower Pledge Agreement, as
                  amended, may be unenforceable in whole or in part, but the
                  inclusion of such provisions does not affect the validity of
                  the Shared Security Documents, taken as a whole, and the
                  Shared Security Documents, taken as a whole, together with
                  applicable law, contains adequate provisions for the practical
                  realization of the benefits of the security created thereby;

                           (c) I express no opinion as to the effect on the
                  opinions expressed herein of (i) the compliance or
                  non-compliance of the Collateral Agent, the Agent, any of the
                  Lenders or any of the other Secured Parties with any state,
                  federal or other laws or regulations applicable to them or
                  (ii) the legal or regulatory status or the nature of the
                  business of the Collateral Agent, the Agent, any of the
                  Lenders or any of the other Secured Parties;

                           (d) I express no opinion as to the enforceability of
                  any rights to contribution or indemnification provided for in
                  the Specified Documents which are violative of the public
                  policy underlying any law, rule or regulation (including any
                  federal or state securities law, rule or regulation);

                           (e) I express no opinion as to the enforceability of
                  (i) any provision of any Specified Document to the extent it
                  authorizes or permits any party to any Specified Document or
                  any purchaser of a participation interest from any such party
                  to set-off or apply any deposit, property or indebtedness with
                  respect to any participation interest or (ii) any provision of
                  any Specified Document to the extent it purports to waive any
                  objection a Person may have that a suit, action or proceeding
                  has been brought in an inconvenient forum;

                           (f) enforcement of the Shared Security Documents
                  against the rights of the Borrower in instruments, leases or
                  contracts may be subject to the terms of such instruments,
                  leases or contracts or other arrangements between the Borrower
                  and the other parties to such agreements, the rights of such
                  other parties and any claims or defenses of such other parties
                  against the Borrower arising under or outside such
                  instruments, leases or contracts or other agreements; and

                           (g) I have assumed that the Specified Documents are
                  the legal, valid and binding obligations of each party thereto
                  other than the Borrower, enforceable against each such party
                  thereto in accordance with its terms.

                  Based upon and subject to the foregoing, I am of the opinion
that:



                                      -21-
<PAGE>   22
                  1. The Borrower is a corporation duly organized, validly
existing and in good standing under the laws of the State of Michigan. The
Borrower has corporate power and authority to own its property and to transact
the business in which it is engaged or presently proposes to engage. The
Borrower is duly qualified to do business as a foreign corporation and is in
good standing in the Commonwealths of Massachusetts and Virginia.

                  2. The Borrower has corporate power and authority to execute,
deliver, perform, and take all actions contemplated by, the Specified Documents,
and all such action has been duly and validly authorized by all necessary
corporate proceedings on its part. Without limitation of the foregoing, the
Borrower has the corporate power and authority to borrow and request Letters of
Credit (as defined in the Specified Documents) to be issued pursuant to the
Specified Documents to the fullest extent permitted thereby from time to time,
and has taken all necessary corporate action to authorize such borrowings and
requests for issuance of Letters of Credit.

                  3. Each of the Specified Documents has been duly and validly
executed and delivered by the Borrower.

                  4. No Federal or Michigan Governmental Action is or will be
necessary in connection with execution and delivery of the Specified Documents,
performance of or compliance with the terms of the Specified Documents, or to
ensure the legality, validity, binding effect, enforceability or admissibility
in evidence of the Specified Documents, except for the matters set forth in
Section 4.04 of each of the Revolving Credit Agreement, the Term Loan Agreement
and the Note Backup Agreement, as the same have been respectively amended by the
Cumulative Amendment.

                  5. Neither the execution and delivery of the Specified
Documents, nor performance of or compliance with the terms and conditions of the
Specified Documents by the Borrower, does or will

                  (a)  violate or conflict with any Federal or Michigan Law, or

                  (b) violate or conflict with, or constitute a default under,
         or result in (or give rise to any right, contingent or other, of any
         Person to cause) any termination, cancellation, prepayment or
         acceleration of performance of, or result in the creation or imposition
         of (or give rise to any obligation, contingent or other, to create or
         impose) any Lien upon any property of the Borrower or any Subsidiary of
         the Borrower (except for any Lien in favor of the Collateral Agent
         securing the Obligations) pursuant to, (i) the articles of
         incorporation or by-laws (or other constitutional documents) of the
         Borrower or any Subsidiary of the Borrower, or (ii) any judicial or
         administrative order, judgment, injunction or decree, any material
         agreement or instrument (including without limitation the Senior Note
         Indenture), or to my knowledge after due inquiry any other agreement or
         instrument, to which the Borrower or any Subsidiary of the Borrower is
         a party or by which any of their respective properties may be subject
         or bound.

                  6. To the best of my knowledge, there is no pending or
threatened action, suit, proceeding or investigation by or before any
Governmental Authority against or affecting the Borrower or any Subsidiary of
the Borrower, except for matters that if adversely decided, individually or in
the aggregate, do not, and would not be likely to, have a Material Adverse
Effect (as defined in the Specified Documents).

                  7. In the event that a Michigan court were to apply the
substantive laws of the State of Michigan, notwithstanding the choice of law of
the parties set forth in the Specified Documents and the 



                                      -22-
<PAGE>   23
limited nature of contacts within the State of Michigan, each of the Specified
Documents constitutes a valid and binding obligation of the Borrower,
enforceable against the Borrower in accordance with its terms. I call to your
attention that the Specified Documents are governed by the laws of the
Commonwealth of Pennsylvania, and I express no opinion as to whether a Michigan
court would apply the substantive laws of the State of Michigan to such
documents.

                  8. The Borrower is not an "investment company" under the
Investment Company Act of 1940, as amended.

                  9. The Borrower is not a "holding company," or a "public
utility company" within the meaning of the Public Utility Holding Company Act of
1935, as amended.

                  This opinion is being furnished to you and is solely for your
benefit in connection with the Specified Documents and the transactions
contemplated by the foregoing, except that it may be relied upon by any person
which becomes a Participant or Secured Party as if it were addressed to such
person and delivered on the date hereof.

                                                              Very truly yours,

                            NOTES TO THE CONSOLIDATED

                              FINANCIAL STATEMENTS


1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a.  Business

The Company is a global information services company with businesses
strategically focused in supplying financial, economic and market research
information to financial and corporate markets.

b.  Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Primark
Corporation and its majority-owned subsidiaries (the "Company"). All significant
intercompany transactions and balances have been eliminated. Investments in
companies of less than 50 percent are accounted for using the equity method.

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 those estimates.

Effective January 1996, Datastream International Limited and its affiliates and
Vestek Systems, Inc. changed their year-end reporting period from November 30 to
December 31. The change was made to provide more timely information and enhance
comparability. The operating results for December 1995 were credited directly to
retained earnings. 

Certain reclassifications have been made to prior years' statements to conform
to the 1997 presentation. Prior periods have been restated to separately present
continuing operations from discontinued operations (Note 3).

c. Foreign Currency Translation 

The functional currency for most of the Company's foreign operations is the
applicable local currency. Foreign currency accounts are translated into U.S.
dollars using current exchange rates in effect at the balance sheet date for
assets and liabilities, and weighted average monthly exchange rates during the
period for revenues and expenses. Adjustments resulting from translating foreign
functional currency financial statements into U.S. dollars are reported as a
separate component of shareholders' equity. Gains and losses resulting from
transactions and certain balance sheet accounts denominated in currencies other
than the applicable functional currency are included in income. The net effect
of changes in cash are separately identified in the consolidated statements of
cash flows.

d.  Derivative Financial Instruments

The Company enters into currency exchange and interest rate swap agreements to
minimize interest rate and foreign exchange risk. Gains and losses related to
qualifying accounting hedges of firm commitments are deferred and recognized in
income when the hedged transaction occurs. Gains and losses from financial
instruments that do not qualify for hedge accounting are marked to market and
recognized as a gain or loss in the current period. The Company does not hold or
issue derivative financial instruments for trading purposes. 

e. Revenue Recognition 

Revenue derived from subscription contracts is generally billed in advance of
services provided. Amounts billed in advance are recorded as deferred income and
recognized ratably over the periods in which services are performed.

f. Cash and Cash Equivalents 

Cash and cash equivalents represent cash and short-term, highly liquid
investments with original maturities of three months or less.

g. Goodwill 

Goodwill represents the excess of the purchase price over the fair value of net
identifiable assets acquired and is amortized on a straight line basis over
estimated useful lives ranging from 20 to 40 years. The Company regularly
evaluates the net carrying value of all long-lived assets, including intangibles
and goodwill, for recoverability based upon the undiscounted future cash flows
associated with these assets. Management believes there have been no impairments
of these assets.

h. Capitalized Software 

Costs related to the conceptual formulation and design of software developed for
internal use are expensed as incurred. Costs incurred subsequent to
establishment of technological feasibility are capitalized and amortized over
periods ranging from 3 to 5 years. Costs to support or service software are
expensed as incurred. The Company does not develop software for sale or lease.

i. Capitalized Data and Other Intangibles 

Costs incurred to update and maintain the Company's database assets are expensed
as incurred. Costs associated with the purchase of historical data not currently
part of the Company's database assets, as well as the cost of initiating a new
database product, are capitalized. Other intangible assets and liabilities
consist of non-compete covenants, trademarks and unfavorable lease commitments.
Data and other intangibles are amortized on a straight line basis over periods
ranging from 3 to 20 years.

                                    CONTINUED



j. Property and Equipment 

Computer equipment and other property are recorded at cost and depreciated on a
straight line basis over their estimated useful lives, ranging from 3 to 10
years. Leasehold improvements are amortized over the shorter of the remaining
life of the lease or the estimated useful life of the improvement.

k. Income Taxes 

Income tax expense is based on reported earnings before income taxes. Deferred
income taxes reflect the impact of temporary differences between assets and
liabilities recognized for financial reporting purposes and such amounts
recognized for tax purposes. Deferred tax balances are adjusted to reflect
changes in tax rates expected to be in effect during the periods in which the
temporary differences reverse. As temporary differences reverse, the related
deferrals are recorded to income.

l. Earnings Per Share 

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128 "Earnings Per
Share." This standard requires dual presentation of basic and diluted earnings
per share ("EPS") on the face of the income statement and requires a
reconciliation of the numerators and denominators of basic and diluted EPS
calculations (Note 8). The EPS of prior periods have been restated to present
basic and diluted EPS.

m. Accounting For Stock-Based Compensation 

The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations. The impact of recording
stock-based compensation under the fair value method is disclosed in Note 10.

n. New Accounting Pronouncements 

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income" and
SFAS No. 131 "Disclosures about Segments of an Enterprise and Related
Information." The Company will adopt these statements during fiscal year 1998
and does not expect that the adoption will have a material impact on the
consolidated financial statements.

2. ACQUISITIONS 

During the three years ending December 31, 1997, the Company made the
acquisitions set forth below, each of which has been accounted for as a
purchase. Accordingly, the purchase price has been allocated to the identifiable
net assets acquired. The excess of the purchase price over the estimated fair
value of net assets acquired has been allocated to goodwill and is amortized on
a straight line basis over periods ranging from 25 to 40 years. Future
adjustments to the total purchase price allocation, if any, are not expected to
materially affect the Company's financial statements. The consolidated financial
statements include the operating results of each business from the date of
acquisition.

ICV

On October 24, 1996, the Company acquired all the outstanding stock of ICV
Limited. The purchase price, excluding fees, consisted of $24,007,000 in net
cash, 2,200,000 shares of Primark common stock at a $27.25 market value and
$8,250,000 in six year notes (the "ICV Purchase Notes"), issued by the Company
to the sellers (Note 6b). ICV supplies a variety of real-time data and news
products to equity traders and investors in London and throughout the United
Kingdom. In accordance with the terms of the purchase agreement, the Company
registered the 2,200,000 shares of its common stock in 1998.

Worldscope

On October 15, 1996, the Company acquired an additional 30% ownership interest
in Worldscope for $5,000,000 in cash, giving Primark a controlling ownership
interest of 80%. Prior to the transaction, Worldscope was a 50% partnership
accounted for under the equity method. In connection with the transaction,
Primark and the previous 50% owner each forgave working capital advances equal
to $3,889,000. The sellers of the 30% interest in Worldscope have a non-expiring
option to sell their remaining 20% ownership to Primark, in increments of 5% or
15%. The price of a 5% increment would be at 5 times the most recent 12 months
of revenue multiplied by the 5% ownership. The price of a 15% increment would be
at 4 times revenue multiplied by the 15% ownership. As of October 15, 2006,
Primark will have the right to purchase an additional 15% of Worldscope.

August 1998 and future contingent payments to the former Yankee shareholders
based upon future operating results, ranging from $0 to a maximum of
$27,000,000. Future contingent payments, if any, are due in the year 2000 and
will be recorded as goodwill when incurred. The Yankee Group provides market
research on telecommunications and computer systems.

</TABLE>

TASC

On December 8, 1997, the Company entered into an agreement to sell its
subsidiary, TASC, Inc. subject to shareholder approval (Note 14), for $432
million in cash, subject to adjustment, including changes in the TASC
consolidated equity account through the date of closing. The sale of TASC
represents disposal of essentially all of the Company's applied technology
segment. On a consolidated basis, TASC had revenues of $437.9, $383.7, and
$346.2 million for the years ended December 31, 1997, 1996 and 1995,
respectively. The purchaser has agreed to indemnify the Company from and against
all expenses and liabilities Primark may incur related to an outstanding claim
against TASC.

TIMCO

In June 1997, the Company adopted a formal plan to sell its non-core
transportation services segment consisting of Triad International Maintenance
Corporation ("TIMCO"). TIMCO reported revenues of $113.3, $106.4 and $79.2
million for the years ended December 31, 1997, 1996 and 1995, respectively. The
Company anticipates that the sale of TIMCO will be completed by June 30, 1998.

PSLC

On September 30, 1996, the Company sold all of the outstanding stock of Primark
Storage Leasing Corporation ("PSLC"), for $14,300,000 in cash. The disposal of
PSLC resulted in an after-tax gain of approximately $8,400,000 and eliminated
$28,700,000 of non-recourse debt from the Company's balance sheet. The purchaser
has agreed to indemnify the Company from and against all expenses and
liabilities that Primark may incur with respect to any adverse environmental
condition relating to PSLC's natural gas storage fields.

b. Dispositions

On January 7, 1997, the Company completed the sale of its investment in the
Weather Network pursuant to the terms of a sale agreement dated December 5, 1996
for 2,100,000 pounds sterling ($3,500,000). The $2,500,000 pre-tax gain on the
sale has been included in other income.

4.  RESTRUCTURING CHARGES

a.  Disclosure

During the first quarter of 1997, the Company recorded a $1,800,000 pre-tax
charge, or $0.04 per share, at Disclosure to take advantage of new information
technology, reorganization of Disclosure's document business and other actions
aimed at reducing costs and enhancing efficiency. The restructuring provision
included estimated costs for employee severance and other benefits of $981,200,
asset write-downs of $713,600 and idle facility related costs of $105,200. As
part of the restructuring, 114 employees were eliminated. The spending for these
accrued restructuring costs was completed in June 1997.

 b. DAFSA 

During the second quarter of 1997, the Company recorded a restructuring charge
of $5,000,000 related to the integration and downsizing of operations at DAFSA.
Due to DAFSA's unprofitable condition, tax benefits associated with losses
incurred during 1997, including the restructuring charge, were not recognized.
Consequently, the restructuring charge resulted in a $0.18 reduction of earnings
per share in 1997.

When the Company acquired DAFSA in June of 1996, approximately $1,500,000 of
integration costs were recorded in determining the purchase accounting. The
subsequent restructuring charge is the result of a plan to further integrate
DAFSA's personnel, space and product with those of the Company's other
subsidiaries. The $6,500,000 total restructuring provision includes estimated
costs for exiting a line of business of $1,700,000, the future rent cost of
abandoned space of $1,000,000, employee severance and other benefits of
$1,400,000, asset write-downs of $1,200,000 and legal, professional and other
related costs of $1,200,000. The accrual for abandoned space will be utilized
over the remaining life of the lease. As of December 31, 1997, $4,800,000 of
restructuring costs had been incurred, of which $1,500,000 related to exiting a
line of business, $1,100,000 related to employee severance and other benefits,
$1,200,000 related to asset write-downs and abandoned lease space and $1,000,000
related to legal, professional and other related costs. As part of the
restructuring, 31 employees of DAFSA have

been terminated and an additional 9 employees will be terminated in 1998. The
restructuring plan, when fully implemented, is expected to significantly improve
DAFSA's operating margins.

5.  LEASES

The Company leases a variety of assets principally under non-cancelable
operating lease agreements, including office facilities, real property, and
computer and office equipment. These leases expire at various dates through
2008. Total rent expense for all operating leases was $15,105,000, $11,563,000,
and $7,649,000 for the years ended December 31, 1997, 1996 and 1995,

6.  SHORT-TERM AND LONG-TERM DEBT

On February 7, 1997, the Company entered into a $300,000,000
refinancing arrangement to replace some of the funds expended for recent
acquisitions and enhance liquidity for future opportunities. The new
arrangement, comprised of a $75,000,000 revolving credit facility (the "Credit
Facility") and a $225,000,000 term loan (the "Term Loan") replaced an
outstanding $75,000,000 revolving credit facility and a $125,000,000 term loan
and provided $8,382,000 as a note backup agreement. The Company incurred costs
of $2,831,000 in conjunction with the arrangement, which will be amortized over
the term of the debt. The write-off of unamortized debt issue costs related to
the original financing generated an extraordinary after-tax loss of $1,955,000
in the first quarter of 1997. The Company recognized an extraordinary after-tax
loss of $534,000 for the write-off of unamortized debt issue costs associated
with the June 1995 refinancing of its $75,000,000 revolving credit facility.
Deferred debt issue costs are amortized over the terms of the related debt,
ranging from 3 to 18 years.

The Credit Facility expires on October 15, 2000 and bears interest on
outstanding borrowings based upon performance pricing which results in rates
ranging from 0.50% to 1.00% above the current prevailing LIBOR rate. Commitment
fees are payable quarterly at rates ranging from 0.20% to 0.30% per annum on the
average daily unused portion of the facility. The Credit Facility contains
various restrictive covenants, which, among other things, require the Company to
maintain certain minimum levels of consolidated net worth and specific
consolidated liquidity and long-term solvency ratios. The Credit Facility is
secured by a pledge of the outstanding common stock of certain of Primark's
subsidiaries.

Required principal payments on long-term debt and notes payable
over the next five years, excluding the Senior Notes and capital lease and other
obligations, are $15,000,000 in 1998, $20,000,000 in 1999, $30,000,000 in 2000,
$35,000,000 in 2001, and $53,250,000 in 2002.

Primark's 8.75% Senior Notes due 2000 ("Senior Notes") are carried
at their principal amount due at maturity less the unamortized discount.
Interest on the Senior Notes is payable semi-annually on April 15 and October

requirements, and are redeemable in whole or in part at the option of the
Company at redemption prices ranging from 104.375% to 100.00% in 1999 and
thereafter, plus accrued interest. The Indenture pursuant to which the Senior
Notes were issued contains various restrictive covenants. Under the most
restrictive covenants, the Company is restricted from paying cash dividends on
its common stock, repurchasing its common stock or making certain other payments
which in the aggregate exceed the sum of: (i) $10,000,000; (ii) 50% of the
Company's consolidated net income (cumulative from the date of issuance of the
Senior Notes); plus (iii) 100% of the net proceeds received from sales of the
Company's common stock for cash.

The Term Loan is due through June 30, 2004. Principal payments are due
semi-annually on June 30 and December 31. Interest on outstanding borrowings
under the Term Loan is payable at rates ranging from 0.50% to 1.25% above the
current prevailing LIBOR rate of interest. The Term Loan contains various
restrictive covenants which, among other things, require the Company to maintain
certain minimum levels of consolidated net worth and specific consolidated
liquidity and long-term solvency ratios. The Term Loan is secured by a pledge of
the outstanding common stock of certain of the Company's subsidiaries.

On October 24, 1996, the Company entered into five loan note agreements totaling
$8,250,000 in connection with the purchase of ICV (Note 2b). The ICV Purchase
Notes are due October 24, 2002. Interest on the ICV Purchase Notes is payable
quarterly at the current prevailing LIBOR rate. In November 1997, the Company
paid $500,000 of the ICV Purchase Notes. On February 7, 1997, the Company
entered into a $8,382,000 Note Backup Agreement (the "Note Agreement") which
expires on November 8, 2002. Under the terms of the Note Agreement, standby
letters of credit were issued to provide credit enhancement for the payment of
the Notes. Interest on outstanding borrowings under the Note Agreement is based
upon performance pricing and payable at rates ranging from 0.75% to 1.25% above
the current prevailing LIBOR rate of interest. Letter of credit fees are based
upon performance pricing and are payable quarterly at a rate of 0.25% per annum
on the average daily unused portion of the facility. As of December 31, 1997,
the Company had no outstanding borrowings under the Note Agreement.

7.  FINANCIAL INSTRUMENTS

a.  Foreign Exchange Risk Management
The Company enters into forward exchange and currency option contracts to reduce
the exposure of foreign currency fluctuations associated with certain firm
commitments and anticipated cash flows. The Company's principal strategy is to
protect the net cash flow from foreign customers' contracts. As these contracts
are typically under two years in length, most of the derivative financial
instruments are similarly two years or less in duration. The Company principally
enters into contracts to deliver foreign currencies for U.S. dollars at
agreed-upon exchange rates. Other contracts include the purchase of British
pounds and Irish Punts for U.S. dollars. Counterparties to these agreements are
major international financial institutions. The tables below illustrate the U.S.
dollar equivalent of foreign exchange contracts at December 31, 1997 and 1996
along with unrecorded gross unrealized gains and losses.

b.  Interest Rate Swap Agreement

On August 1, 1995, the Company entered into an interest rate swap agreement with
a major bank, having a notional principal amount of $18,333,000. The swap
agreement effectively changed the interest rate of a portion of Primark's
long-term debt from a floating rate to a 6.1% fixed rate. This swap agreement
expires in December of 1999. As of December 31, 1997, the notional principal
amount outstanding was $8,333,000. Though the Company is exposed to credit and
market risk in the event of future non-performance by the bank, management does
not anticipate that such an event will occur.

</TABLE>


Estimated fair values of these financial instruments were based upon quotes
obtained from investment and commercial bankers using comparable securities. The
fair values of currency forward contracts and currency options were estimated
based on quoted market prices of contracts with similar terms. Other financial
instruments have been excluded as their carrying value approximates their market
value. 

8. EARNINGS PER SHARE 

In February of 1997, the FASB released SFAS No. 128, "Earnings per Share",
effective for fiscal periods ending after December 15, 1997. The statement
simplifies the standards for computing EPS and makes them comparable to
international EPS standards. The statement replaces primary EPS with basic EPS.
Basic EPS is computed by dividing income available to common shareholders by the
weighted-average number of common shares outstanding for the period. Diluted EPS
reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock or
resulted in the issuance of common stock. Diluted EPS is computed similarly to
fully diluted EPS previously presented. In accordance with the standard, all
prior period EPS data has been restated.

Options to purchase 785,000; 227,000 and 19,000 shares of common stock were
outstanding for the years ended 1997, 1996 and 1995 respectively but were
excluded in the computation of diluted EPS because the options' exercise price
was greater than the average market price of common shares. The conversion of
preferred stock outstanding during 1995 and the first quarter of 1996 was
excluded from the

</TABLE>


In December of 1997, the Company received 722,000 shares of its common stock to
satisfy the exercise price of stock options and payment of withholding taxes due
on option exercises totaling $29,604,000. These shares were retired upon
receipt. The Company drew on its revolving credit facility to satisfy the
withholding tax payment. Primark will receive a compensation deduction related
to the option exercises and anticipates a tax refund of approximately
$25,000,000.

In April 1997, the Company's Board of Directors authorized the
repurchase of up to 2,200,000 shares of the Company's common stock from time to
time through open market and/or privately negotiated transactions. During the
second quarter of 1997, the Company repurchased 1,349,000 shares of its
outstanding common stock in the open market at a total cost of $26,633,000. On
May 13, 1997 and June 5, 1997, the Company retired 1,145,300 and 203,700 shares,
respectively.

On October 24, 1996, the Company issued 2,200,000 shares of its common stock as
part of the purchase price for ICV Limited (Note 2b).

On May 2, 1996, the Company received notification to convert the total
outstanding shares of Primark Series A, 8.5% Cumulative Convertible Preferred
Stock into shares of Primark common stock. The 674,943 preferred shares plus
accrued and unpaid dividends were converted into 1,164,276 shares of Primark
common stock based upon the stated conversion rate of $14.49. The preferred
shares were held entirely by the Profit Sharing and Stock Ownership Plan of
TASC, a discontinued subsidiary (Note 3).

                                    CONTINUED


On December 5, 1995, the Company completed an equity offering in which it sold
4,068,200 shares of its common stock and offered an additional 288,000 shares
for certain selling shareholders. The sale of common stock together with option
proceeds related to the selling shareholders provided the Company $107,784,000,
net of commissions and expenses. A portion of the proceeds was used to pay down
the outstanding balance of $48,166,000 on the Company's revolving credit
agreement and to prepay $15,000,000 on a loan held by TASC, a discontinued
subsidiary (Note 3).

In December of 1995, 92,000 shares of the Company's common stock were delivered
to satisfy the exercise price of stock options and 168,000 shares were withheld
from the exercise of stock options to satisfy the related tax withholding
requirements.

b.  Rights Agreement

In May of 1997, the Board of Directors of the Company executed a new Rights
Agreement (the "Rights Agreement") to extend the benefits of the rights
agreement adopted in 1988. The Company's Rights Agreement is designed to deter
coercive or unfair takeover tactics, and to prevent a buyer from gaining control
of the Company without offering a fair price to all of its shareholders. The
Rights Agreement generally becomes effective when an "Acquiring Person" (as
defined in the agreement) beneficially owns 15% or more of the outstanding
shares of Primark's common stock. In general, upon a "Triggering Event" (as
defined in the agreement), each Right represents the right to purchase one share
of Common Stock of the Company at a price per share of $138.00, subject to
adjustment. The Rights, which do not have voting privileges, are redeemable
under certain circumstances at $0.01 per Right and will expire on January 25,
2008, unless previously redeemed. At December 31, 1997, common stock reserved
for issuance under the Rights Agreement was 26,800,399 shares.

10.  RETIREMENT AND BENEFIT PLANS

a.  Employee Savings and Stock Ownership Plan

The Primark Corporation Savings and Stock Ownership Plan was amended and revised
effective January 1, 1997 ("ESSOP") to provide for 401(K) contributions,
employer matching contributions and certain other changes. Prior to the
amendment, the plan, which covers all employees of Primark and certain
subsidiaries, was pre-funded in 1989 with 965,000 shares of the Company's common
stock which were allocated to participants, based upon a percentage of
compensation, through 1996. Under the current 401(K) provisions of the ESSOP,
the Company matches 50% of an employee's contribution up to a maximum of 3% of
each participant's compensation. Participating employees' future benefits are
based on their vested portion of contributions, plus their pro rata share of
fund investment gains or losses. Under the 401(K) provisions, the Company
contributed $1,629,000 during 1997. No contributions were made to the ESSOP
during 1996 and 1995.

b.  Foreign Plans

Substantially all employees in foreign countries who are not U.S. citizens are
covered by various retirement benefit arrangements, some of which are considered
to be defined benefit pension plans for accounting purposes. Benefits are based
primarily on years of service and employees' salaries near retirement. In
general, plans are funded based upon legal requirements, tax considerations,
local practices and investment opportunities. Plan assets are generally held in
restricted trusts or foundations that are segregated from the assets of the plan
sponsor, and consist primarily of common stock and fixed income securities. The
components of net periodic pension cost for foreign defined benefit pension
plans are shown below.

c.  Employee Stock Purchase and Stock Option Plans

Established in 1992, the Primark Corporation Employee Stock Purchase Plan is
available for all employees of Primark and certain subsidiaries. Under this plan
employees may purchase, through periodic payroll deductions, up to a maximum of
3,000,000 shares of the Company's common stock at 85% of the lower of the
average market price of such shares either at the beginning or end of each six
month offering period.

The Primark Corporation Stock Option Plan for Non-Employee Directors provides
for the granting of options to purchase shares of common stock to each director
who is not an employee. The Primark Corporation 1992 Stock Option Plan provides
for the granting of options to purchase common stock to officers and certain key
employees of Primark and its subsidiaries. This plan limits the number of shares
subject to option that may be granted to any participant in any year to 100,000
shares. Stock options available for grant in any one year under Primark
Corporation's 1992 Stock Option Plan may not exceed 1.5% of the Company's
outstanding common stock as of January 1 each year, plus any excess of available
stock options not granted from previous years. At December 31, 1997, options
available for grant in 1998 included 449,513 stock options under Primark
Corporation's 1992 Stock Option Plan. Generally, options outstanding under the
Company's stock option plans: (i) are granted at prices equal to the fair market
value of the stock on the date of grant, (ii) vest within a three year period,
and (iii) expire ten years subsequent to award.

Changes in the number of options granted under the Company's various stock
option plans are shown below.

It should be noted that the option-pricing model used was designed
to value readily tradable stock options with relatively short lives. The options
granted to employees are not tradable and have contractual lives of up to ten
years. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. However,
management believes that the assumptions used and the model applied to value the
awards yields a reasonable estimate of the fair value of the grants made under
the circumstances.

The Company uses the intrinsic value method to measure compensation expense
associated with grants of stock options to employees. Had compensation cost been
determined based upon the fair value at the grant date for awards under these
plans, reported net income and earnings per share would have been as follows:

The 1997 adjustment of Federal income taxes provided in prior years
is primarily due to the recognition of net operating losses and the true up of
prior year tax expense. The 1996 adjustment is primarily the result of the
Company settling seven open tax years at lower than anticipated levels.

The tax effects of significant temporary differences that gave rise to deferred
income tax assets and liabilities are shown below.

12.  SEGMENT AND GEOGRAPHIC INFORMATION

During 1997 and 1996, the Company realigned its business segments
to reflect its strategic emphasis in the information services industry. The
realignment included several acquisitions throughout 1996 and 1997 (Note 2) as
well as the discontinuance of two of its previously reported segments, applied
technology and transportation services during 1997 (Note 3). Accordingly, the
Company's continuing operations primarily reflect that of one industry segment,
information services, which provides services and related products principally
in the United States and the United Kingdom. Most of Primark's international
sales are generated through its affiliates, which are located throughout Europe,
Asia and the United States.

The Company's operations by geographic region are presented in the following
table on a stand-alone basis. Information presented includes acquired companies
from their respective dates of acquisition (Note 2), and has been restated to
exclude discontinued operations (Note 3).

13.  COMMITMENTS AND CONTINGENCIES

The Company and its subsidiaries are involved in other administrative
proceedings and matters concerning issues arising in the ordinary course of
business. Management cannot predict the final disposition of such issues, but
believes that adequate provision has been made for the probable losses and the
ultimate resolution of these proceedings will not have a material adverse effect
on the Company's financial condition, results of operations or financial
liquidity.

14.  SUBSEQUENT EVENTS

a.  Sale of TASC

On March 30, 1998, the shareholders of Primark approved the terms of a stock
purchase agreement providing for the sale of TASC and its subsidiaries to Litton
Industries, Inc. (Note 3).

b.  Refinancing

In March 1998, the Company amended the terms of its revolving credit facility
and term loan agreements. Under the terms of the amendment, which will become
effective upon the consummation of the TASC sale, the Company will prepay its
$112,000,000 Senior Notes and its $220,000,000 outstanding term loan and replace
its outstanding $75,000,000 credit facility with a $225,000,000 revolving credit
facility expiring in 2000. Interest on the borrowings under the new revolving
credit facility is payable at rates ranging from 0.05% to 1.00% above the
current prevailing LIBOR rate of interest.

                                   MANAGEMENT


Management of Primark Corporation and its subsidiaries (the "Company") is
responsible for the preparation and integrity of the accompanying consolidated
financial statements and other financial information contained in this Annual
Report. Management believes that all such information has been prepared in
conformity with generally accepted accounting principles, and necessarily
includes certain amounts that are based on management's judgments and estimates.
The consolidated financial statements have been audited by Deloitte & Touche
LLP, the Company's independent Certified Public Accountants. Their audit was
made in accordance with generally accepted auditing standards, as indicated in
their report, and included a review of the Company's system of internal
accounting controls and tests of transactions to the extent they considered
necessary to carry out their responsibilities.

In management's opinion, the Company's system of internal accounting controls,
coupled with an ongoing program of internal audits to review such controls,
provide reasonable assurance that the Company's assets are safeguarded from
material loss and the transactions are executed and recorded in accordance with
established procedures. The system is supported by formal policies and
procedures, including an active Code of Conduct program intended to ensure key
employees adhere to the highest standards of personal and professional
integrity. The concept of reasonable assurance is based on the recognition that
the cost of maintaining a system of internal accounting controls should not
exceed the related benefits to be derived.

The Audit Committee of the Board of Directors, composed solely of outside
directors, meets periodically with management, internal auditors and Deloitte &
Touche LLP to review planned audit scope and results and to discuss other
matters affecting the adequacy of internal accounting controls and the quality
of financial reporting. Deloitte & Touche LLP has full and free access to the
Audit Committee and may meet with the committee without management
representatives present.

                          CERTIFIED PUBLIC ACCOUNTANTS

TO THE BOARD OF DIRECTORS OF PRIMARK CORPORATION:
We have audited the accompanying consolidated statements of financial position
of Primark Corporation and its subsidiaries as of December 31, 1997 and 1996 and
the related consolidated statements of income, cash flows and common
shareholders' equity for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. 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, such consolidated financial statements present fairly, in all
material respects, the financial position of Primark Corporation and its
subsidiaries at December 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles.

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



RESULTS OF OPERATIONS:

Primark reported net income of $19.7 million ($0.71 per share) for the twelve
months ended December 31, 1997 compared to $36.8 million ($1.38 per share) in
1996 and $16.9 million ($0.82 per share) in 1995. Net income for 1997 and 1995
includes an after tax extraordinary loss of $2.0 million ($0.07 per share) and
$0.5 million ($0.03 per share) for the write off of debt issue costs associated
with bank debt which was successfully refinanced.

Primark reported income from continuing operations of $7.0 million ($0.25 per
share) for the year ended December 31, 1997, compared to $12.5 million ($0.46
per share) and $5.4 million ($0.19 per share) in 1996 and 1995, respectively.
The 1997 income from continuing operations includes restructuring charges of
$6.2 million ($0.22 per share), net of tax, taken at DAFSA and Disclosure during
the first half of 1997. Excluding the restructuring charges, 1997 income from
continuing operations increased 5.4% to $13.2 million ($0.47 per share). The
Company's decision to discontinue the operations of TASC and TIMCO in 1997, as
well as PSLC in 1996, affected income from continuing operations for all
periods.

During 1996 and 1997, management pursued a strategy of focusing the Company's
operations on its information services businesses. In connection with that
strategy, the Company discontinued three operating segments as discussed below
and acquired several businesses in the information industry. The Company is in
the preliminary stages of investigating further organizational changes to
address the best way to manage the remaining information services segment. This
investigation includes, among other things, the examination of all tangible and
intangible assets of the Company for possible adjustment.

On December 8, 1997, the Company entered into an agreement for the sale of TASC
for $432 million in cash. The Company estimates the sale will generate a net
gain of approximately $179.9 million. On March 30, 1998 the shareholders of
Primark approved the sale. Consequently, the operating results and net assets of
TASC have been reclassified from continuing operations and recorded as a
discontinued operation for all periods presented. As an essential part of the
transaction, TASC and Primark entered into an information technology services
agreement. Under this agreement, TASC will continue to provide Primark
information technology research and development, planning, and technical
assistance for a three year period. TASC will also continue to manage the
Primark Telecommunications Network and supply professional information
technology services to the business units of Primark and their customers. TASC
generated net income of $15.0, $13.0 and $9.7 million, for the twelve months
ended December 31, 1997, 1996 and 1995, respectively.

In June of 1997, the Company adopted a formal plan to dispose of its
transportation business, TIMCO. Accordingly, the operating results and net
assets of TIMCO have been reclassified from continuing operations and recorded
as a discontinued operation for all periods presented. During the three years
ended 1997, 1996 and 1995, TIMCO generated net losses of $0.3 million, net
income of $2.4 million and $2.7 million, respectively.

In September of 1996, the Company sold its financial services segment, PSLC,
which resulted in a $8.4 million gain, net of tax. Discontinued operations for
the twelve months ended December 31, 1996 and 1995 include net income of $0.8
and $1.0 million.

Acquisitions during the first quarter of 1997 and last half of 1996, together
with the Company's stock repurchase program, resulted in the Company increasing
its level of funded debt. As a result, interest costs from continuing operations
increased $3.5 million and $4.1 million during 1997 and 1996. The Company
allocated interest costs to each of the discontinued operations based upon their
ratios of net assets proportional to total net assets. After the allocation of
interest cost to discontinued operations, the Company reported interest expense
of $16.0 million, $12.5 million and $8.4 million for the years ended 1997, 1996
and 1995, respectively. It is the Company's intention to repay all funded debt
with the proceeds from the sale of TASC and eliminate substantially all interest
costs.

During 1997, the Company's effective tax rate increased due to the
non-deductibility of goodwill created by certain of its recent acquisitions and
because no tax benefits have been recorded for the $8.6 million of net losses
incurred at DAFSA for the year. In 1996, the Company's effective tax rate
received a favorable impact from settling seven years of open tax returns.

The Company has a formal plan and task force assigned to make all of its
financial systems, product offerings and related databases year 2000 compliant.
In 1997 the Company spent $1.5 million of resources on this endeavor and
anticipates that it will be required to spend an additional $2.7 million and
$2.6 million in 1998 and 1999, respectively, to be year 2000 compliant. The
majority of the remaining year 2000 work will be performed at Datastream/ICV.

* Pro forma results include the results of recent acquisitions for the full year
periods.

For the year ended December 31, 1997, revenues increased 43.6% and 115.3% over
the same periods in 1996 and 1995. The increase is primarily due to the effect
of the acquisitions of Baseline and WEFA during the first quarter of 1997; ICV,
the Yankee Group, DAFSA and a controlling interest in Worldscope during 1996;
and Disclosure and I/B/E/S in 1995. On a pro forma basis to include the effect
of acquisitions, the Company grew 1997 revenues and operating income 6.7% and
17.6%, respectively, over the same period in 1996. These pro forma growth rates
include adverse currency movements and restructuring charges, a resized DAFSA
and Disclosure's paper based product fall-off.

DAFSA had the single most significant negative impact on operating income during
1997. During 1997, DAFSA generated revenue of $5.5 million but incurred
operating losses of $8.4 million, which included a $5.0 million restructuring
charge. The restructuring program was implemented in the second quarter of 1997
and, together with the introduction of technology and applications developed at
Disclosure and WEFA, DAFSA was able to achieve near break-even results during
the fourth quarter of 1997.

Datastream/ICV:

During 1997, the Datastream/ICV operation grew revenues 8.8%. These businesses
experienced most of the negative impacts of currency fluctuations. Excluding the
effects of currency and exchange fees, the Datastream/ICV operation grew
revenues approximately 13.1% for the year. Exclusive of currency effects, ICV's
Topic3 product line grew 19.2% for the year but overall revenues were offset by
declining exchange fee revenues. ICV's overall margins increased due to shifts
in product mix, primarily the reduction of minimum margin exchange fee revenues.
Excluding the effects of currency, Datastream grew revenues 12.7% for the year.
Datastream's annual growth in revenues was led by increases in the UK of 9.4%,
the Americas of 10.4%, Continental Europe of 17.3% and Asia of 15.1%. Including
the effects of currency, the Pacific Basin accounted for $21.1 million of
Datastream's annual revenues. The Company reduced investment in the Far East
region in early 1997 and does not plan to risk any further capital until
management believes the current period of adjustment comes to an end.

Disclosure/Worldscope:

Disclosure and Worldscope generated revenues of $88.5 million for the year, a
decrease of 3.0% compared to the same period in 1996. Overall growth in revenues
was impacted by the 14.1% decrease in paper demand business. Disclosure's
electronic products now represent approximately 40% of total revenues and
continue to do very well with 29.9% growth in revenues for 1997. At the
beginning of 1996, the electronic products represented less than 19.6% of
Disclosure's total revenue.

Financial Analytics:

The financial analytics group, comprised of I/B/E/S, Baseline, WEFA and Vestek,
generated $90.6 million of revenues for the year. As a group, on a pro forma
basis, these operations grew revenues 24.7% over 1996. The strong performance in
the year was lead by I/B/E/S, Baseline and Vestek, which had record growth in
revenues of 42.9%, 32.8% and 18.3%, respectively.

Yankee:

The Yankee Group was originally acquired, in part, to be the market research arm
of the Company's applied technology segment, focusing on identifying current
trends and future directions in communications and computer industries for
commercial, industrial and consumer markets. With the disposition of TASC,
management has folded Yankee in with information services. Yankee finished the
year with pro forma revenue growth of 11.2%.

CAPITAL RESOURCES & LIQUIDITY:

Primark ended 1997 with $12.8 million in cash and cash equivalents compared to
$25.3 in 1996 and $59.9 in 1995. During 1997, $86.1 million was used to purchase
Baseline and WEFA, $56.2 million to repurchase and retire stock and $43.9
million to fund capital expenditures. Partially offsetting these uses were cash
flows from operating activities which generated $ 58.0 million, the issuance of
long-term debt that provided $97.2 million, net of debt issue costs, and the
sale of the Weather Network which generated $3.5 million. During 1996, the
Company acquired four separate businesses for $71.1 million in net cash, $8.3
million in seller notes, 2.2 million shares of common stock and $7.6 million of
other consideration. Primark also increased capital expenditures

                                    CONCLUDED



$20.8 million over 1995. The 1996 cash expenditures were primarily funded from
cash on the balance sheet, the sale of PSLC for $14.3 million and increased
operating cash flows. During 1995, the Company issued $125.0 million of
commercial bank debt and $106.5 million of common stock that provided funds
partially used for the acquisition of Disclosure and I/B/E/S for $199.7 million
in net cash.

Operating cash flows decreased $7.7 million during 1997. The decrease reflects a
decline in net income primarily attributable to the restructuring charges,
decreases in deferred income, and tax refunds due. The tax refunds arose as the
Company accepted stock from certain employees to pay taxes due on their option
exercises in accordance with the Company's benefit policies. The Company
received a compensation deduction associated with the option exercises, which
should result in approximately $25 million of tax refunds to be received in
1998. The increase between 1995 and 1996 primarily represents additional cash
flows from acquired companies offset by increased working capital requirements.
All periods benefited from improving growth in the base businesses.

Cash flows from financing activities provided $74.7 million for the year, a
$70.0 million increase over the same period in 1996. The increase is primarily
the result of the $300.0 million bank refinancing arrangement on February 7,
1997 which provided an additional $100.0 million in long term debt. The new
arrangement is comprised of a $75.0 million revolving credit facility and a
$225.0 million term loan expiring in June 2004. The new financing replaced an
outstanding $75.0 million revolving credit facility and a $125.0 million term
loan. The Company incurred costs of $2.8 million in conjunction with the
arrangement that will be amortized over the term of the debt. The additional
borrowings increased Primark's debt to total capital ratio from 34.3% at
December 31, 1996 to 44.0% at December 31, 1997. Partially offsetting this
increase was $56.2 million used to repurchase the Company's common stock
comprised of $26.6 million for a stock buy back program and $29.6 million
associated with the Company's acceptance of stock from certain employees to pay
withholding taxes on option exercises. These repurchased shares were retired
during the year. At year end, the Company had $27.6 million outstanding on its
revolving credit facility primarily as a result of withholding taxes due on
stock options exercised in December. During 1996, the Company entered into
several non cash financing transactions including the conversion of its $16.9
million redeemable preferred stock to 1.2 million shares of common stock and the
issuance of 2.2 million shares of common stock in connection with the
acquisition of ICV. During 1995, the Company entered into a $200.0 million
credit arrangement with several banks to support the Disclosure and I/B/E/S
acquisition. The credit arrangement included a $75.0 million revolving credit
facility and a $125.0 million term loan which were refinanced in 1997. In
December of 1995, the Company sold 4.1 million shares of common stock for $107.8
million and used the net proceeds to repay loan balances and for other general
corporate purposes.

Investing activities, primarily for acquisitions, used $144.5 million of cash
during 1997, compared to $106.0 million in 1996 and $226.7 million in 1995. The
majority of 1997 investing uses were for the purchases of Baseline and WEFA,
which used $41.2 and $44.9 million, respectively. Capital expenditures and
capitalized software amounted to $43.9 million during the year, an increase of
$7.6 million over the same period in 1996. The majority of the expenditures were
for computer equipment, leasehold improvements for new facilities at I/B/E/S and
ICV, and capitalized software and data for upgrading and revising Disclosure's
product line and production operation. Partially offsetting these uses were
proceeds from the Company's sale of its investment in the Weather Network that
provided $3.5 million of cash. During 1996, the Company acquired four separate
operations with net cash consideration totaling $71.1 million. The sale of PSLC
partially offset these uses, providing $14.3 million. During 1995, Primark
purchased Disclosure and I/B/E/S for $199.7 million in net cash.

The Company anticipates the sale of TASC for $432 million during the first
quarter of 1998 will generate approximately $345 million of cash after taxes and
related expenses are paid. It is the intention of management to repay the Senior
Notes and any outstanding bank debt at the closing of the transaction.

In June of 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive Income"
and SFAS No. 131 "Disclosures about Segments of an Enterprise and Related
Information." The Company will adopt these statements during fiscal year 1998
and does not expect that the adoption of these statements will have a material
impact on the consolidated financial statements.

Changes in foreign exchange rates during 1997 negatively impacted the Company's
revenues and operating income by approximately $3.2 million and $4.9 million,
respectively. Management anticipates that the international component of its
revenues and operating income will be approximately 50% and 55%, respectively
during 1998. The Company will continue to manage foreign currency risk through
its hedging program.

      While not computed in accordance with generally accepted accounting
      principles, EBITDA is a widely used measure of a company's performance in
      its industry because it assists in comparing performance on a consistent
      basis without regard to depreciation and amortization, which may vary
      significantly depending on accounting methods (particularly where
      acquisitions are involved). Management of the Company believes that EBITDA
      is a meaningful measure given the widespread industry acceptance as a
      basis for financial analysis. Further, certain of the Company's debt
      agreements include financial covenants that are based upon EBITDA, as
      defined above. Due to the variety of methods that may be used by companies
      and analysts to calculate EBITDA, the EBITDA measures presented herein may
      not be comparable to that presented by other companies.
