"Agreement"), among THE THOMSON CORPORATION, a corporation incorporated under
the laws of the Province of Ontario ("Parent"), INFOBLADE ACQUISITION
CORPORATION, a Delaware corporation and an indirect wholly owned subsidiary of
Parent ("Purchaser"), and each of the parties identified on Schedule I hereto
(each, a "Stockholder" and, collectively, the "Stockholders"), as individual
stockholders of NEWSEDGE CORPORATION, a Delaware corporation (the "Company"),

                              W I T N E S S E T H:

            WHEREAS, the Purchaser wishes to commence an offer to all
stockholders of the Company to tender their shares of Common Stock, par value
$0.01, of the Company for the offer price of $2.30 per share of Common Stock
(the "Offer");

            WHEREAS, concurrently with the execution of this Agreement, Parent
and Purchaser are entering into an Agreement and Plan of Merger dated as of the
date hereof (the "Merger Agreement"; capitalized terms used and not otherwise
defined herein shall have the respective meanings assigned to them in the Merger
Agreement) with the Company, pursuant to which (i) Purchaser will commence the
Offer, and (ii) following consummation of the Offer, Purchaser shall merge with
and into the Company;

            WHEREAS, as a condition to entering into the Merger Agreement and
incurring the obligations set forth therein, including the Offer, Parent and
Purchaser have required that each of the Stockholders enter into this Agreement
in order to provide for the tender of their respective Shares (as defined below)
to the Offer and the voting of such Shares at any meeting of the stockholders of
the Company in favor of the approval and adoption of the Merger Agreement, the
Merger and all the transactions contemplated by the Merger Agreement and
otherwise in such manner as may be necessary to consummate the Merger; and

            WHEREAS, the Stockholders believe that it is in the best interests
of the Company and its stockholders to induce Parent and Purchaser to enter into
the Merger Agreement and, therefore, the Stockholders are willing to enter into
this Agreement.

            NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and intending to be legally bound
hereby, the parties hereto agree as follows:

                                    ARTICLE I
                            TENDER OF SHARES; OPTIONS

            SECTION 1.01. TENDER OF SHARES. Each Stockholder, severally but not
jointly, agrees that, as soon as practicable following commencement of the
Offer, such Stockholder shall tender or cause to be tendered all of such
Stockholder's respective
<Page>

Shares (as defined below) pursuant to and in accordance with the terms of the
Offer, and shall not withdraw such Shares from the Offer unless the Offer is
terminated. Each Stockholder, severally but not jointly, acknowledges and agrees
that Purchaser's obligation to accept for payment the shares of Common Stock in
the Offer, including any Shares tendered by such Stockholder, is subject to the
terms and conditions of the Offer. For the purposes of this Agreement "Shares"
shall mean: (i) all shares of Common Stock of the Company and all such shares of
Common Stock issuable upon the exercise or conversion of options, warrants and
other rights to acquire shares of Common Stock (other than those which are
cancelled in accordance with Sections 3.07 and 3.08 of the Merger Agreement or
Section 1.02 hereof) owned of record and /or beneficially by each Stockholder as
of the date of this Agreement; and (ii) all additional shares of Common Stock of
the Company (including any shares of Common Stock received as a result of a
stock split, recapitalization, combination, exchange of shares or the like) and
all additional such shares of Common Stock issuable upon the exercise or
conversion of additional options, warrants and other rights to acquire shares of
Common Stock of the Company (other than those which are cancelled in accordance
with Sections 3.07 and 3.08 of the Merger Agreement or Section 1.02 hereof)
which each Stockholder acquires ownership of, of record and/or beneficially,
during the period from the date of this Agreement through the termination of the
Offer. When used with respect to any Share, the "beneficial ownership" thereof
or similar terms means the power to vote or dispose of, or direct the voting or
disposition of, such Share. Each Stockholder hereby agrees, while this Agreement
is in effect, to promptly notify Parent and Purchaser of the number of any new
Shares acquired by such Stockholder, if any, after the date hereof.

            SECTION 1.02. OPTIONS. Each Stockholder, severally but not jointly,
agrees, subject to the terms and conditions of the Merger Agreement, to the
cancellation of each outstanding option and/or warrant to purchase shares of
Common Stock of the Company held by such Stockholder as set forth on Schedule I
hereto, in exchange for the consideration, if any, described in Sections 3.07
and 3.08 of the Merger Agreement.

                                   ARTICLE II

            SECTION 2.01. VOTING AGREEMENT. Each Stockholder, severally but not
jointly, hereby agrees that, from and after the date hereof and until the
Expiration Date, at any meeting of the stockholders of the Company, however
called, and in any action by consent of the stockholders of the Company, such
Stockholder shall vote (or cause to be voted) such Stockholder's Shares (i) in
favor of the approval and adoption of the Merger Agreement, the Merger and all
the transactions contemplated by the Merger Agreement and this Agreement and
otherwise in such manner as may be necessary to consummate the Merger; (ii)
except as otherwise agreed to in writing by Parent, against any action,
proposal, agreement or transaction that would result in a breach of any
covenant, obligation, agreement, representation or warranty of the Company under
the Merger Agreement or of the Stockholder contained in this Agreement; and
(iii) against (A) any action, agreement or transaction that would impair or
materially delay the ability


                                       2
<Page>

of the Company to consummate the transactions provided for in the Merger
Agreement or (B) any Acquisition Proposal.

            SECTION 2.02. IRREVOCABLE PROXY. Each Stockholder hereby irrevocably
appoints Parent and each of Parent's executive officers as such Stockholder's
true and lawful attorney, agent and proxy, to vote and otherwise act (by written
consent or otherwise) with respect to such Stockholder's Shares at any meeting
of stockholders of the Company (whether annual or special and whether or not an
adjourned or postponed meeting) or by written consent in lieu of any such
meeting or otherwise, on the matters and in the manner specified in Section
2.01, giving and granting to such Stockholder's attorney, agent and proxy the
full power and authority to do and perform each and every act and thing whether
necessary or desirable to be done in and about the premises, as fully as it
might or could do if personally present with full power of substitution,
appointment and revocation, hereby ratifying and confirming all that such
Stockholder's attorney, agent and proxy shall do or cause to be done by virtue
hereof (the "Irrevocable Proxy"). THIS PROXY AND POWER OF ATTORNEY ARE
IRREVOCABLE (UNTIL THE EXPIRATION DATE) AND COUPLED WITH AN INTEREST AND, TO THE
EXTENT PERMITTED UNDER APPLICABLE LAW, SHALL BE VALID AND BINDING ON ANY PERSON
TO WHOM A STOCKHOLDER MAY TRANSFER ANY OF SUCH STOCKHOLDER'S SHARES IN BREACH OF
THIS AGREEMENT. Each Stockholder hereby revokes all other proxies and powers of
attorney with respect to such Stockholder's Shares that may have heretofore been
appointed or granted, and no subsequent proxy or power of attorney shall be
given or written consent executed (and if given or executed, shall not be
effective) by any Stockholder with respect thereto prior to the Expiration Date.
All authority herein conferred or agreed to be conferred shall survive the death
or incapacity of any Stockholder and the termination of the Irrevocable Proxy
and any obligation of the Stockholder under this Agreement shall be binding upon
the heirs, personal representatives, successors and assigns of such Stockholder.
This proxy shall terminate on the Expiration Date.

            SECTION 2.03. CONFLICTS. In the case of any Stockholder who is a
director of the Company, no provision of this Agreement, including Section 5.02
hereof, shall prevent or interfere with such Stockholder's performance of such
Stockholder's obligations, if any, solely in such Stockholder's capacity as a
director of the Company, including, without limitation, the fulfillment of such
Stockholder's fiduciary duties, and in no event shall such performance
constitute a breach of this Agreement.

                                   ARTICLE III
               REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS

cancellation of, or result in the creation of a Lien on any of the Shares of
such Stockholder pursuant to, any note, bond, mortgage, indenture, contract,

decree or other instrument or obligation to which such Stockholder is a party or
by which such Stockholder or the Shares of such Stockholder are bound or

delay such Stockholder from performing its obligations under this Agreement.

            (b) To the knowledge of such Stockholder, the execution and delivery
of this Agreement by such Stockholder do not, and the performance of this
