     WHEREAS, concurrently with the execution and delivery of this Agreement,

                      ---------------

however, with respect to the preceding clause (ii) of this sentence, that if the
- -------
Option cannot be exercised by reason of any applicable government order then the
Option shall not terminate until the tenth business day after such impediment to
exercise shall have been removed or shall have become final and not subject to
appeal. Notwithstanding the foregoing, the Option may not be exercised if
Desktop is in breach in any material respect of any of its covenants or
agreements contained in the Merger Agreement.

local governmental authority or instrumentality, if any, required in connection
with the issuance of the Option Shares hereunder shall have been obtained or
made, as the case may be; and (b) no preliminary or permanent injunction or
other order by any court of competent jurisdiction prohibiting or otherwise
restraining such issuance shall be in effect.

     4.  Closing
         -------

     At any Closing, (a) Individual shall deliver to Desktop a single
certificate in definitive form representing the number of Individual Shares
designated by Desktop in its Exercise Notice, such certificate to be registered

and (b) Desktop shall pay to Individual the aggregate purchase price of the

     8.  Registration Rights
         -------------------

     (a) Following the termination of the Merger Agreement, each party hereto (a
"Holder") may by written notice (a "Registration Notice") to the other party
 ------                             -------------------                     
(the "Registrant") request the Registrant to register under the Securities Act
      ----------                                                              
all or any part of the shares acquired by such Holder pursuant to this Agreement
(the "Registrable Securities") in order to permit the sale or other disposition
      ----------------------                                                   
of such shares pursuant to a bona fide firm commitment underwritten public

 
                                      -5-

offering in which the Holder and the underwriters shall effect as wide a
distribution of such Registrable Securities as is reasonably practicable and
shall use reasonable efforts to prevent any person or group from purchasing
through such offering shares representing more than 1% of the outstanding shares
of Common stock of the Registrant on a fully diluted basis; provided, however,
                                                            --------  ------- 
that any such Registration Notice must related to a number of shares equal to at
least 2% of the outstanding shares of Common Stock of the Registrant on a fully
diluted basis and that any rights to require registration hereunder shall
terminate with respect to any shares that may be sold pursuant to Rule 144(k)
under the Securities Act.

     (b) The Registrant shall use all reasonable efforts to effect, as promptly
as practicable, the registration under the Securities Act of the Registrable
Securities; provided, however, that (i) neither party shall be entitled to more
            --------  -------                                                  
than an aggregate of two effective registration statements hereunder and (ii)
the Registrant will not be required to file any such registration statement
during any period of time (not to exceed 40 days after a Registration Notice in
the case of clause (A) below or 90 days after a Registration Notice in the case
of clauses (B) and (C) below) when (A) the Registrant is in possession of
material non-public information which it reasonably believes would be
detrimental to be disclosed at such time and, in the written opinion of counsel
to such Registrant, such information would have to be disclosed if a
registration statement were filed at that time; (B) such Registrant is required
under the Securities Act to include audited financial statements for any period
in such registration statement and such financial statements are not yet
available for inclusion in such registration statement; or (C) such Registrant
determines, in its reasonable judgment, that such registration would interfere
with any financing, acquisition or other material transaction involving the
Registrant.  If consummation of the sale of any Registrable securities pursuant
to a registration hereunder does not occur within 180 days after the filing with
the SEC of the initial registration statement therefor, the provisions of this
Section 8 shall again be applicable to any proposed registration, it being
understood that neither party shall be entitled to more than an aggregate of two
effective registration statements hereunder.  The Registrant shall use all
reasonable efforts to cause any Registrable Securities registered pursuant to
this Section 8 to be qualified for sale under the securities or blue sky laws of
such jurisdictions as the Holder may reasonably request and shall continue such
registration or qualification in effect in such jurisdictions; provided,
                                                               -------- 
however, that the Registrant shall not be required to qualify to do business in,
- -------                                                                         
or consent to general service of process in, any jurisdiction by reason of this
provision.

     (c) The registration rights set forth in this Section 8 are subject to the
condition that the Holder shall provide the Registrant with such information
with respect to such Holder's Registrable Securities, the plan for distribution
thereof, and such other information with respect to such Holder as, in the
reasonable judgment of counsel for the Registrant, is necessary to enable the
Registrant to include in a registration statement all material facts required to
be disclosed with respect to a registration thereunder.

     (d) A registration effected under this Section 8 shall be effected at the
registrant's expense, except for underwriting discounts and commissions and the
fees and expenses of counsel to the Holder, and the Registrant shall provide to
the underwriters such documentation (including certificates, opinions of counsel
and "comfort" letters from auditors) as

 
                                      -6-

are customary in connection with underwritten public offerings and as such
underwriters may reasonably require.  In connection with any registration, the
parties agree (i) to indemnify each other and the underwriters in the customary
manner and (ii) to enter into an underwriting agreement in form and substance
customary for transactions of this type with the underwriters participating in
such offering.

     9.  Adjustment Upon Changes in Capitalization
         -----------------------------------------

     (a) In the event of any change in the Individual Shares by reason of stock
dividends, split-ups, mergers (other than the Merger), recapitalizations,
combinations, change of shares and the like, the type and number of shares or
securities subject to the Option, the Exercise Ratio and the Exercise Price
shall be adjusted appropriately, and proper provision shall be made in the
agreements governing such transaction so that Desktop shall receive, upon
exercise of the Option, the number and class of shares or other securities or
property that Desktop would have received in respect of the Individual Shares if
the Option had been exercised immediately prior to such event or the record date
therefor, as applicable.

     (b) In the event of any change in the Desktop Shares by reason of stock
dividends, split-ups, mergers (other than the Merger), recapitalizations,
combinations, exchanges of shares and the like, the type and number of shares or
securities which Desktop can deliver to Individual pursuant to Section 4 hereof
in full payment for any Individual Shares to be purchased and the Exchange Ratio
shall be adjusted appropriately.
 
     10.  Restrictive Legends
          -------------------

     Each certificate representing Option Shares issued to Desktop hereunder,
and each certificate representing Desktop Shares deliver to Individual at a
closing, shall include a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
     ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
     AVAILABLE.  SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
     TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT DATED AS OF NOVEMBER 2,
     1997, A COPY OF WHICH MAY BE OBTAINED FROM DESKTOP DATA, INC.

     11.  Listing
          -------

approval of such listing as soon as practicable.  Desktop, upon the request of
Individual, shall promptly file an application to list the Desktop Shares issued
and delivered to Individual pursuant to Section 4 for quotation on the

 
                                      -7-

listing as soon as practicable.

     12.  Binding Effect
          --------------

     This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns.  Nothing
contained in this Agreement, express or implied, is intended to confer upon any
person other than the parties hereto and their respective successors and
permitted assigns any rights or remedies of any nature whatsoever by reason of
this Agreement.  Any shares sold by a party in compliance with the provisions of
Section 8 shall, upon consummation of such sale, be free of the restrictions
imposed with respect to such shares by this Agreement and any transferee of such
shares shall not be entitled to the rights of such party.  Certificates
representing shares sold in a registered public offering pursuant to Section 8
shall not be required to bear the legend set forth in Section 10.

     13.  Specific Performance
          --------------------

     The parties recognize and agree that if for any reason any of the
provisions of this Agreement are not performed in accordance with their specific
terms or are otherwise breached, immediate and irreparable harm or injury would
be caused for which money damages would not be an adequate remedy.  Accordingly,
each party agrees that in addition to other remedies the other party shall be
entitled to an injunction restraining any violation or threatened violation of
the provisions of this Agreement.  In the event that any action shall be brought
in equity to enforce the provisions of the Agreement, neither party will allege,
and each party hereby waives the defense, that there is an adequate remedy at
law.

     14.  Entire Agreement
          ----------------

     This Agreement and the Merger Agreement (including the appendices thereto)
constitute the entire agreement between the parties with respect to the subject
matter hereof and supersede all other prior agreements and understandings, both
written and oral, between the parties with respect to the subject matter hereof.

     15.  Further Assurances
          ------------------

     Each party will execute and deliver all such further documents and
instruments and take all such further action as may be necessary in order to
constitute the transactions contemplated hereby.

     16.  Validity
          --------

     The invalidity or unenforceability of any provision of this Agreement shall
not affect the validity or enforceability of the other provisions of this
Agreement, which shall remain in full force and effect. In the event any
Governmental Entity of competent jurisdiction holds any provision of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in

 
                                      -8-


good faith and shall execute and deliver an amendment to this Agreement in
order, as nearly as possible, to effectuate, to the extent permitted by law, the
intent of the parties hereto with respect to such provision.
