                              STOCK OPTION PLAN OF
                         DATA BROADCASTING CORPORATION

                    (as amended through September 13, 1994)

     1. PURPOSE OF THE PLAN. Under this First Amended and Restated Stock Option
Plan (the "Plan") of the Company, options may be granted to eligible employees,
officers, and directors to purchase shares of the Company's capital stock. The
Plan is designed to enable the Company and its subsidiaries to attract, retain,
and motivate their employees, officers, and directors by providing for or
increasing the proprietary interest of such persons in the Company. The Plan
provides for options which qualify as incentive stock options ("Incentive
Options") under Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code"), as well as options which do not so qualify.

     2. STOCK SUBJECT TO PLAN. The maximum number of shares of stock for which
options granted hereunder may be exercised shall be 5,000,000 shares of common
stock, $.01 par value per share, subject to the adjustments provided in Sections
6 and 11 hereof. Shares of stock subject to the unexercised portions of any
options granted under this Plan, which expire, terminate or are cancelled, may
again be subject to options under the Plan. If shares are delivered or withheld
from the number of shares otherwise issuable upon an option exercise, in payment
of the option exercise price and/or withholding tax obligations,








<PAGE>   2
such delivered or withheld shares shall not again become subject to options
under the Plan. Further, no option may be granted under this Plan unless, on the
date of grant, the sum of (i) the maximum number of shares issuable at any time
under such option, plus (ii) the number of shares that have previously been
issued pursuant to options granted under the Plan, other than shares that have
been subject to options but pursuant to the terms and conditions of such option
have been forfeited without the participant having received any benefits of
ownership from the forfeited shares, plus (iii) the maximum number of shares
that may be issued at any time after such grant date pursuant to options
outstanding on such date, does not exceed the maximum number of shares for which
this Plan permits options granted hereunder to be exercised.

     3. ELIGIBLE PARTICIPANTS.

       (a) The participants eligible to be considered by the Plan Administrator
(as defined in Section 10 hereof) for the grant of options hereunder are any
persons regularly employed by the Company or its subsidiaries, including
officers and directors, in a managerial capacity on a full-time, salaried basis
("Eligible Employees").

       (b) During the term of the Plan, on the third business day following the
date of public release of the Company's fiscal year-end summary statement of
sales and

                                      -2-



<PAGE>   3
earnings, each person who is on such date a director, but not an Eligible
Employee, may, at the discretion of the Company's stock option committee, be
granted an option with an exercise price equal to the fair market value of the
Company's stock for such date. Such options shall become exercisable on the
earlier of the first anniversary of their grant date or the occurrence of an
event described in the first sentence of Section 11 hereof, and shall expire on
the earlier of the first anniversary of the date the option holder ceases to be
a director of the Company or the tenth anniversary of their grant. The exercise
price for such options and any withholding tax due in connection with such
exercise may be paid by any of the methods described under Section 9 hereof,
unless the Company at the time is prohibited from purchasing or acquiring shares
of its stock.

     4. MAXIMUM EXERCISE PRICE. The exercise price for each option granted
hereunder shall be not less than 100% of the fair market value of the stock at
the date of the grant of the option. The fair market value of the stock as of
the date shall be deemed to equal the average of the high asked and low bid
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers Inc. Automated Quotations system ("NASDAQ"), or any then
operative successor to the NASDAQ system, for such date or, if the stock is then
listed on a national securities exchange, the average of the high and


                                      -3-

<PAGE>   4
low transaction prices reported through the consolidated reporting system for
such date.

     5. NONTRANSFERABILITY. Any option granted under this Plan shall by its
terms be nontransferable by the optionee other than by will or the laws of
descent and distribution and is exercisable during the optionee's lifetime only
by him or by his guardian or legal representative.

     6. ADJUSTMENTS. If the outstanding shares of stock of the class then
subject to this Plan are increased or decreased, or are changed into or
exchanged for a different number or kind of shares or securities, in any such
case as a result of one or more reorganizations, recapitalizations, stock
splits, reverse stock splits, stock dividends or the like, appropriate
adjustments shall be made in the number and/or kind of shares or securities for
which options may thereafter be granted under this Plan and for which options
then outstanding under this Plan may thereafter be exercised. Any such
adjustment in outstanding options shall be made without changing the aggregate
exercise price applicable to the unexercised portions of such options.

     7. MAXIMUM OPTION TERM. No options granted under this Plan may be exercised
in whole or in part more than ten years after its date of grant.

                                      -4-


<PAGE>   5
     8. PLAN DURATION. Options may not be granted under this Plan more than ten
years after the date of the adoption of the Plan, or of the shareholder approval
thereof, whichever is earlier.

     9. PAYMENT. Payment for stock purchased upon any exercise of an option
granted under this Plan, and payment of any withholding tax obligation arising
in connection with such exercise, shall be made in full in cash concurrently
with such exercise, except that, if and to the extent the instrument evidencing
the option so provides or the Plan Administrator so permits, and if the Company
is not then prohibited from purchasing or acquiring shares of such stock, such
payment may be made in whole or in part with shares of the same class of stock
as that then subject to the option, or with shares otherwise issuable upon
exercise of the option, delivered or withheld in lieu of cash concurrently with
such exercise, the shares so delivered or withheld to be valued on the basis of
the fair market value of the stock (determined in a manner specified in the
instrument evidencing the option) on the day preceding the date of exercise.

     10. ADMINISTRATION. The Plan shall be administered by the Company's board
of directors (the "Board") or, in the discretion of the Board, by a committee of
not less than two members of the Board (the Board or such committee if

                                      -5-
<PAGE>   6
designated by the Board, is referred to herein as the "Plan Administrator").

     The interpretation and construction by the Plan Administrator of any term
or provision of the Plan or of any option granted under it shall be final,
unless otherwise determined by the Board, in which event such determination by
the Board shall be final. The Plan Administrator may from time to time adopt
rules and regulations for carrying out this Plan and, subject to the express
provisions of this Plan, may prescribe the form or forms of the instruments
evidencing any option granted under this Plan.

     Subject to the express provisions of this Plan, the Plan Administrator
shall have full and final authority in its discretion to select the employees
and directors to be granted options, to grant such options and to determine the
number of shares to be subject thereto, the exercise prices, the terms of
exercise, exercisability and/or vesting, the terms of expiration, termination or
forfeiture, and other pertinent provisions thereof.

     11. CORPORATE REORGANIZATIONS. Upon the dissolution or liquidation of the
Company, or upon a reorganization, merger or consolidation of the Company as a
result of which the outstanding securities of the class then


                                      -6-
<PAGE>   7


subject to options hereunder are charged into or exchanged for cash or property
or securities not of the Company's issue, or upon a sale of substantially all
the property of the Company to, or the acquisition of stock representing more
than eighty percent (80%) of the voting power of the stock of the Company then
outstanding by, another corporation, group or person, the Plan shall terminate,
and all options theretofore granted hereunder shall terminate, unless provision
be made in writing in connection with such transaction for the continuance of
the Plan and/or for the assumption of options theretofore granted, or the
substitution for such options of options covering the stock of a successor
employer corporation, or a parent or a subsidiary thereof, with appropriate
adjustments as to the number and kind of shares and prices, in which event the
Plan and options theretofore granted shall continue in the manner and under the
terms so provided. If the Plan and unexercised options shall terminate pursuant
to the foregoing sentence, all persons entitled to exercise any unexercised
portions of options then outstanding shall have the right, at such time prior to
the consummation of the transaction causing such termination as the Plan
Administrator shall designate, to exercise the unexercised portions of their
options, including the portions thereof which would, but for this paragraph
entitled "Corporate Reorganizations" not yet be exercisable. The instrument
evidencing any option may also provide for such acceleration of


                                      -7-
<PAGE>   8


otherwise unexercisable portions of the option upon other specified events or
occurrences, such as involuntary terminations of the option holder's employment
following certain changes in the control of the Company.

     12. STOCK APPRECIATION RIGHTS AND LIMITED RIGHTS. If the instrument
evidencing the option so provides (as determined by the Plan Administrator), an
option granted to an Eligible Employee under this Plan (herein sometimes
referred to as the "corresponding option") may include the right upon any
exercise (a "Stock Appreciation Right") or upon exercise following the
occurrence of any event provided for in the instrument evidencing the option (a
"Limited Right" and, together with Stock Appreciation Rights, "Rights") to
receive an amount equal to some or all of the excess of the fair market value
(determined in a manner specified in the instrument evidencing the corresponding
option) of the shares subject to unexercised portions of the corresponding
option over the aggregate exercise price of such shares under the corresponding
option as of the date the Right is exercised. The amount payable upon exercise
of a Right may be paid in cash or in shares of the class then subject to the
corresponding option (valued on the basis of their fair market value, determined
by the Plan Administrator as specified with respect to the measurement of the
amount payable as aforesaid), or in a combination of cash and such shares so


                                      -8-
<PAGE>   9


valued. No Right may be exercised in whole or in part (a) other than in
connection with the contemporaneous surrender without exercise of such
corresponding option, or the portion thereof that corresponds to the portion of
the Right being exercised, or (b) except to the extent that the corresponding
option or such portion thereof is exercisable (including pursuant to Section 11
of the Plan) on the date of exercise of the Right, or (c) unless the class of
stock then subject to the corresponding option is then "publicly traded." For
this purpose, a class of stock is "publicly traded" if it is listed or admitted
to unlisted trading privileges on a national securities exchange or if sales or
bid and offer quotations therefor are reported on NASDAQ or on any then
operative successor to the NASDAQ system.

     13. RESTRICTED STOCK. If the instrument evidencing the option so provides,
shares of stock issued on exercise of an option granted to an Eligible Employee
under this Plan may upon issuance be subject to the following restriction (and,
as used herein, "restricted stock" means shares issued on exercise of options
granted under this Plan which are still subject to restrictions imposed under
this Section 13 that have not yet expired or terminated):

          (a) shares of restricted stock may not be sold or otherwise
transferred or hypothecated;


                                      -9-
<PAGE>   10


          (b) if the employment of the holder of shares of restricted stock with
the Company or a subsidiary is terminated for any reason other than his death,
normal or early retirement in accordance with his employer's established
retirement policies or practices, or total disability, the Company (or any
subsidiary designated by it) shall have the option for sixty (60) days after
such termination of employment to purchase for cash all or any part of his
restricted stock at the lesser of (i) the price paid therefor by the holder, or
(ii) the fair market value of the restricted stock on the date of such
termination of employment (determined in a manner specified in the instrument
evidencing the option); and

          (c) as to the shares of stock affected thereby, any additional
restrictions that may be imposed on particular shares of restricted stock as
specified in the instrument evidencing the option.

     The restrictions imposed under this Section 13 shall apply as well to all
shares or other securities issued in respect of restricted stock in connection
with any stock split, reverse stock split, stock dividend, recapitalization,
reclassification, spin-off, split-off merger, consolidation or reorganization,
but such restrictions shall expire or terminate at such time or times as shall
be specified therefor in the instrument evidencing the option which provides for
the restrictions.

     14. FINANCIAL ASSISTANCE. The Company is vested with authority under this
plan to assist any employee to whom an option is granted hereunder (including
any director or officer of the Company or any of its subsidiaries who is also an
employee) in the payment of the purchase price payable on exercise or that
option, by lending the amount of such purchase price to such employee on such
terms and at such rates of interest and upon such security, (or unsecured) as
shall have been authorized by or under authority of the Plan Administrator.

     5. AMENDMENT AND TERMINATION. The Board may alter, amend, suspend or
terminate this Plan, provided that no such action shall deprive an optionee,
without his consent, of any option granted to the optionee pursuant to this Plan
or of any of his right under such option. Except as herein provided, no such
action of the Board, unless taken with the approval of the shareholders of the
Company, may:

          (a) materially increase the benefits accruing to participants under
the Plan;

          (b) materially increase the number of securities which may be issued
under the Plan; or

          (c) materially modify the requirements as to eligibility for
participation in the Plan.

<PAGE>   12


     The provisions of Section 3(b) relating to the amount, price and timing of
awards shall not be amended more than once every six months (other than to
comport with changes in the Internal Revenue code, the Employee Retirement
Income Security Act, or the rules thereunder) and any amendment to the
provisions of Section 3(b) shall, unless approved by the shareholders of the
Company, become effective no sooner than six months after approval of the
amendment by the Board.
