                        PRIMARK AGREES TO ACQUISITION BY
                             THE THOMSON CORPORATION
                 Thomson to Make $38 Per Share Cash Tender Offer


WALTHAM, MA, and TORONTO, ONTARIO, June 5, 2000 - Primark Corporation (NYSE/PCX:
PMK) and The Thomson Corporation (TSE: TOC) today jointly announced a merger
agreement under which Thomson will acquire Primark.

Under terms of the agreement, unanimously approved by the Boards of Directors of
both companies, Thomson will make a cash tender offer for all shares of Primark
stock at US$38.00 per share, or approximately US$842 million. Thomson will also
assume approximately US$235 million in Primark debt.

Joseph E. Kasputys, Primark's Chairman and Chief Executive Officer, will become
Chairman of Thomson Financial. "This acquisition by Thomson is consistent with
Primark's three primary objectives: serving the best interests of our customers,
providing career opportunities for our talented employees and enhancing
shareholder value. We strongly believe that Thomson Financial, with its industry
expertise, world-class content and significant resources, is the ideal partner
for Primark. Shareholders, customers and employees of both organizations will
realize exceptional benefits from this combination," stated Kasputys.

"With the acquisition of Primark, Thomson is taking another significant step to
strengthen its global information offerings, in particular, the content and
software applications we provide to the financial services market," commented
Richard J. Harrington, President and Chief Executive Officer of The Thomson
Corporation. "Primark's extensive data, analytical tools and workflow solutions
are extremely complementary to our existing products and will provide
significant added value to Thomson's current customers. In addition, Primark's
strong European and international operations will greatly expand Thomson
Financial's global presence and capabilities - a key requirement to service
these high-growth market opportunities."

"We are extremely excited to be adding a company of Primark's caliber to the
Thomson Financial family," said Patrick J. Tierney, President and Chief
Executive Officer of Thomson Financial. "Primark's highly regarded analytical
product range and innovative desktop applications will enhance our offerings to
the fund management, investment banking and brokerage communities, and provide
new and far-reaching channels for distributing our broad content offerings. We
look forward to working with the Primark team to provide our customers with an
expanded portfolio of products and services."

The transaction, which is expected to be completed during the second half of the
year, is conditioned upon the tender of 51% of the eligible shares, the
expiration or termination of customary regulatory approvals, and other customer
closing conditions.
