                          INTERACTIVE DATA CORPORATION

                          2000 LONG-TERM INCENTIVE PLAN

                            OPTION GRANT CERTIFICATE

                             (EXECUTIVE LEVEL GRANT)

      This Option Grant Certificate, together with the summary of grant award
(the "Grant Summary"), evidences the grant by Interactive Data Corporation
(f/k/a Data Broadcasting Corporation) (the "Company") on the date (the "Grant
Date") that appears on the Grant Summary presented to the individual (the
"Grantee") whose name appears on the Grant Summary, of an option to purchase, in
whole or in part, the specific number of shares of Stock set forth on the Grant
Summary (at the exercise price, vesting schedule and other terms set forth
therein), pursuant to the provisions of the 2000 Long-Term Incentive Plan (the
"Plan") and on the terms and conditions set forth below. Capitalized terms used
herein and not defined herein shall have the meanings ascribed thereto in the
Plan.

      It is intended that to the extent possible, the option evidenced by this
Option Grant Certificate shall be an incentive stock option as defined in
Section 422 of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code"). The Company shall have no
liability to the Grantee, or any other party, if the option (or any part
thereof) is not an incentive stock option.

      Except as otherwise indicated by the context, the term "Grantee", as used
in connection with this Option Grant Certificate, shall be deemed to include any
person who acquires the right to exercise this option validly under its terms.

1.    Vesting in the Event of a Change in Control:

      (i) Notwithstanding the vesting schedule set forth on the Grant Summary,
any unvested option shares shall automatically vest and become exercisable
immediately upon termination of the Grantee's employment if the Grantee's
employment is terminated within one (1) year following a Change in Control (x)
by the Company (other than for Cause) or (y) by the Grantee for Good Reason.

      (ii) In addition, notwithstanding the vesting schedule set forth on the
Grant Summary, any unvested option shares shall automatically vest and become
exercisable immediately prior to the occurrence of a Change in Control if, in
connection with the Change in Control, shares of Stock will no longer be listed
on a recognized national securities exchange; provided, however, in the event
that in connection with such a Change in Control, the holders of Stock will
receive a cash payment for each share of Stock surrendered pursuant to such
transaction (the "Acquisition Price"), then the Committee may instead provide
that all outstanding Options shall terminate upon consummation of such
transaction and that the Grantee shall receive, in exchange therefore, a cash
payment equal to the amount (if any) by which (x) the Acquisition Price
multiplied by the number of shares of Stock subject to such outstanding Options
(whether or not then exercisable), exceeds (y) the aggregate exercise price of
such Options.

<PAGE>

      For purposes of this Option Grant Certificate, Change in Control shall
mean the occurrence of any of the following events at any time after the Grant
Date:

      (a)   The acquisition by any individual, entity or group (within the
            meaning of Sections 13(d) and 14(d) of the Securities Exchange Act
            of 1934, as amended (the "Exchange Act") or any successor provisions
            thereto) of beneficial ownership (as defined in Rule 13d-3 of the
            Exchange Act or any successor provision thereto), directly or
            indirectly, of securities of the Company representing more than 50%
            of the combined voting power of the Company's then outstanding
            voting securities; provided, however, that for purposes of this
            subsection (a), the following acquisitions shall be disregarded: (x)
            any acquisition by any employee benefit plan (or related trust)
            sponsored or maintained by the Company or any corporation controlled
            by the Company, (y) any acquisition by a corporation owned directly
            or indirectly by the stockholders of the Company in substantially
            the same proportions as their ownership of stock of the Company, or
            (z) any acquisition by Pearson plc ("Pearson");

      (b)   The consummation of a merger, consolidation, or reorganization of
            the Company with or involving any other entity or the sale or other
            disposition of all or substantially all of the Company's assets (any
            of these events being a "Business Combination"), unless, immediately
            following such Business Combination, either of the following
            conditions is satisfied:

                  (x) all or substantially all of the individuals and entities
            who were the beneficial owners of the outstanding voting securities
            of the Company immediately prior such Business Combination
            beneficially own, directly or indirectly, at least 50% of the
            combined voting power of the voting securities of the resulting or
            acquiring Entity in such Business Combination (which shall include,
            without limitation, a corporation which as a result of such Business
            Combination owns the Company or substantially all of the Company's
            assets either directly or through one or more subsidiaries) (such
            resulting or acquiring Entity is referred to herein as the
            "Surviving Entity") in substantially the same proportions as their
            ownership of the outstanding voting securities of the Company
            immediately prior to such Business Combination, or

                  (y) Pearson beneficially owns, directly or indirectly, 50% or
            more of the combined voting power of the then-outstanding voting
            securities of the Surviving Entity; or

      (c)   The stockholders of the Company approve a plan of complete
            liquidation of the Company.

      Notwithstanding the foregoing, a Change in Control will not be deemed to
      have occurred with respect to the Grantee if the Grantee is part of a
      purchasing group that consummates the Change in Control transaction. The
      Grantee shall be deemed "part of a purchasing group" for purposes of the
      preceding sentence if the Grantee is either directly or indirectly an
      equity participant in the purchasing group (except for (A) passive
      ownership of less than 3% of the stock of the purchasing group, or (B)
      ownership of equity participating in the purchasing group which is
      otherwise not significant, as determined prior to the Change in Control by
      the Committee).

      (d) For purposes of this Option Grant Certificate, Good Reason shall mean
any significant diminution in the Grantee's title, authority, or
responsibilities or any reduction in the annual base cash compensation of more
than 10%.

      (e) For purposes of this Option Grant Certificate, Cause shall mean (i)
the Grantee's material breach of any term of any written agreement with the
Company, including without limitation any violation of confidentiality and/or
non-competition agreements; (ii) the Grantee's conviction for any act of fraud,
theft, criminal dishonesty, or any felony; (iii) the Grantee's engagement in
illegal conduct, gross misconduct, or act(s) involving moral turpitude which is
materially and demonstrably injurious to the Company; or (iv) the Grantee's
willful failure (other than any such failure resulting from incapacity due to
physical or mental illness), which failure is not cured within 30 days of
written notice to the Grantee from the Company, to perform his or her reasonably
assigned material responsibilities to the Company. For purposes of (iv), no act
or failure to act by the Grantee shall be considered "willful" unless it is
done, or omitted to be done, in bad faith and without reasonable belief that the
Grantee's action or omission was in the best interests of the Company.

2.    Termination of Option (the "Grant Expiration Date"): The Grantee's
ability to exercise his/her right to purchase shares of Stock pursuant this
grant shall terminate on the earliest to occur of:

      (i)   the 10th anniversary of the Grant Date (the "Final Exercise Date");

      (ii)  as to any unvested portion of this option, the termination
            (including voluntary resignation) of the Grantee's employment (and
            if such termination is for Cause, as to the vested portion as well);

     (iii)  as to any vested portion of this option, unless earlier terminated
            in connection with a transaction described in Section 1(ii) above or
            as set forth parenthetically in Section 2(ii) above, three months
            following termination (including voluntary resignation) of the
            Grantee's employment; and

      (iv)  such earlier times as described in the Plan.

                                       -3-

3.    Assignment of Company's Rights and Obligations: Except as provided in
Section 1 (ii) above, in the event of a Change in Control, the Company shall
assign this Option Grant Certificate and the related Grant Summary and all of
its rights and obligations thereunder to the acquiring or surviving entity, such
entity shall assume in writing all of the obligations of the Company relative to
this option, and the Company (in the event and so long as it remains in business
as a going concern) shall remain liable for the performance of its obligations
thereunder in the event of a failure of the acquiring entity to perform its
obligations thereunder.

4.    Acquired Rights: The award of this option: (i) does not form part of
the Grantee's contract of employment (if any); (ii) does not constitute a
contract of employment; and (iii) does not entitle the Grantee to any benefits
other than those granted under the Plan. Benefits granted under the Plan are not
part of the Grantee's ordinary salary, and shall not be considered part of such
salary for pension purposes or in the event of severance, redundancy or
resignation. If the Grantee's employment is terminated for any reason, the
Grantee agrees that he or she shall not be entitled to any sum, shares or other
benefit intended to compensate the Grantee for the loss or diminution in value
of any actual or prospective rights, benefits or expectations under or in
relation to the Plan.

      The Grantee understands and accepts that the benefits granted under the
Plan are entirely at the discretion of the Company and that the Company retains
the right to amend, modify or terminate the Plan at any time, in its sole
discretion and, except as may otherwise be provided in the Plan, without notice.

5.    Data Protection: To the extent reasonably necessary to administer the
Plan: (i) the Company may process personal data about the Grantee, including,
but not limited to (a) information concerning this option grant and any changes
hereto, (b) other personal and financial data about the Grantee, and (c)
information about the Grantee's participation in the Plan and shares exercised
under the Plan from time to time; and (ii) the Grantee gives explicit consent to
the Company to (a) process any such personal data, and (b) transfer any such
personal data outside the country in which the Grantee lives, works or is
employed, including, without limitation, to the Company and any of its
subsidiaries and agents, including the outside stock plan administrator as
selected by the Company from time to time, and any other person the Company may
deem appropriate in its administration of the Plan. The Grantee has the right to
access and correct personal data by contacting a local Human Resources
Representative. The transfer of the information outlined here is important to
the administration of the Plan and failure to consent to the transmission of
such information may limit or prohibit the Grantee from participating in the
Plan.

6.    Access to Plan/Incorporation by Reference: The Grantee hereby
acknowledges that he/she has access to a copy of the Plan as presently in
effect. The text and all of the terms and provisions of the Plan, as amended
from time to time, are incorporated herein by reference, and this option is
subject to such terms and provisions in all respects.

7.    Exercise of Option / Tax Withholding:

      (i) Form of Exercise. At any time when the Grantee wishes to exercise this
option, in whole or in part, the Grantee shall transmit to the Company or its
agent notice of exercise in such form as the Committee may determine from time
to time. Each election to exercise this option shall specify that it relates to
this Option Grant Certificate and to the related Grant Summary. The Grantee may
purchase less than the number of shares covered hereby, provided that no partial
exercise of this option may be for any fractional share.

      (ii) Payment of Exercise Price and Tax Withholding. As a condition to
exercise, the Grantee shall remit to the Company the exercise price in cash or
in such other form as permitted under the Plan, plus an amount sufficient to
satisfy any withholding tax obligation of the Company that may arise in
connection with such exercise (or make provision satisfactory to the Company for
the payment of any such withholding obligation). Notwithstanding the foregoing,
in the event a Grantee's applicable tax rate is not readily determinable on the
date of exercise of this option, a tax withholding shall be withheld from the
proceeds due such Grantee using an estimated tax rate. If the actual rate of
withholding tax applicable to the exercise of this option is less than the
amount withheld, then the Grantee will be refunded the difference at a
subsequent Company payroll date.

      (iii) Disqualifying Disposition. If the Grantee disposes of Shares
acquired upon exercise of this option within two years from the Grant Date or
one year after such Shares were acquired pursuant to exercise of this option,
the Grantee shall notify the Company in writing of such disposition.

8.    Nontransferability of Option: This option may not be sold, assigned,
transferred, pledged or otherwise encumbered by the Grantee, either voluntarily
or by operation of law, except by will or the laws of descent and distribution,
and, during the lifetime of the Grantee, this option shall be exercisable only
by the Grantee.
