         WHEREAS, immediately prior to the execution and delivery of this
Agreement, CBS and DBC entered into the Limited Liability Company Agreement of

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein and for other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties hereto, intending to be
legally bound by the terms hereof applicable to each of them, hereby agree as
follows:

                                    ARTICLE I

commitment relates to the period from and after the date hereof (the "Assumed
DBC Liabilities"), other than any Excluded DBC Liabilities.

                  (b) Notwithstanding Section 1.02(a), or any other provision of
this Agreement or any of the other agreements and instruments executed and
delivered in connection herewith and the transactions contemplated hereby,
including, but not limited to, the License Agreement and the DBC Services
Agreement (the "Ancillary Agreements"), and regardless of any disclosure to CBS
or the Company, the Company shall not assume any Excluded DBC Liability, each of

         the DBC Companies not specifically assumed pursuant to Section 1.02(a);

                  (c) The Company shall acquire the DBC Assets free and clear of
all liabilities, obligations and commitments of any of the DBC Companies, other
than the Assumed DBC Liabilities, and free and clear of all Liens (as defined in
Section 3.05), other than Permitted Liens (as defined in Section 3.05).

         SECTION 1.03.  Consents of Third Parties.

                  (a) Notwithstanding anything in this Agreement to the
contrary, this Agreement shall not constitute an agreement to assign any asset
or any claim or right or any benefit arising under or resulting from such asset
if an attempted assignment thereof, without the consent of a third party, would
constitute a breach or other contravention of the rights of such third party,
would be ineffective with respect to any party to an agreement concerning such
asset, or would in any way adversely affect the rights of any of the DBC
Companies or, upon transfer, the Company under such asset. If any transfer or
assignment by any of the DBC Companies to, or any assumption by the Company of,
any interest in, or liability, obligation or commitment under, any asset
requires the consent of a third party, then such assignment or assumption shall
be made subject to such consent being obtained. To the extent any DBC Contract
may not be assigned to the Company by reason of the absence of any such consent,
the Company shall not be required to assume any Assumed DBC Liabilities arising
under such DBC Contract.

                  (b) In connection with those consents that have not been
obtained as of the date hereof, DBC and the Company hereby agree that, until any
such required consent is obtained, DBC, or one or more of its subsidiaries, as
appropriate, shall, with the reasonable and necessary cooperation of the
Company, and at the Company's direction, continue to fulfill any and all
obligations and commitments, and enforce any and all rights, of the DBC
Companies in connection with any asset, claim or right that constitutes a DBC
Asset but for which any required consent has not been obtained, and that the
Company shall be entitled to all of the economic claims, rights and benefits
under such asset, claim or right and DBC shall pay or cause to be paid to the
Company all such economic benefits as promptly as practicable following receipt
by DBC or any of its subsidiaries. To the extent, and only to the extent, a
required consent is received to the transfer of any asset, claim or right, the
Company shall be responsible for the Assumed DBC Liabilities, if any, arising
under such asset, claim or right.

         SECTION 1.04. CBS Contribution. On the terms and subject to the
conditions of this Agreement, CBS will contribute to the Company, over a period
of five years and on the terms set forth in Exhibit D, advertising time with an
aggregate rate card value of $50 million calculated in accordance with the terms
set forth in Exhibit D (the "CBS Contribution" and, together with the DBC
Contribution, the "Contributions"), which contribution is deemed to have a
discounted present value equal to the discounted present value of the DBC
Contribution, in exchange for a 50% membership interest in the Company (the "CBS
Interest").

instruments of transfer relating to the DBC Assets in form and substance
reasonably satisfactory to CBS and the Company and (iii) such other documents as
CBS or the Company have reasonably requested to demonstrate compliance with the
terms and provisions of this Agreement;

                  (b) CBS is delivering (i) appropriately executed copies of
this Agreement and each Ancillary Agreement to which it is specified to be a

requested to demonstrate compliance with the terms and provisions of this
Agreement; and

                                   ARTICLE III

                      Representations and Warranties of DBC

         DBC hereby represents and warrants to CBS and the Company, as of the
date of this Agreement, as follows:

         SECTION 3.01. Organization, Standing and Power. Each of the DBC
Companies is duly organized, validly existing and in good standing under the
laws of the jurisdiction in which it is organized and has full corporate power
and authority and possesses all governmental franchises, licenses, permits,
authorizations and approvals necessary to enable it to own, lease or otherwise
hold its properties and assets and to conduct the Business and its other
businesses as presently conducted, other than such franchises, licenses,
permits, authorizations and approvals the lack of which, individually or in the
aggregate, have not had and could not reasonably be expected to have a material
adverse effect (i) on the business, assets, condition (financial or otherwise)
or results of operations or prospects of DBC and its subsidiaries, taken as a
whole, or of the Business, (ii) on the ability of DBC to perform its obligations
under this Agreement and



                                       5
<PAGE>   9

the Ancillary Agreements or (iii) on the ability of the DBC Companies to
consummate the DBC Contribution and the other transactions contemplated hereby
and thereby (a "DBC Material Adverse Effect"). Each of the DBC Companies is duly
qualified to do business as a foreign corporation in each jurisdiction where the
character of the DBC Assets held by it or the nature of the Business make such
qualification necessary for it to conduct the Business as currently conducted by
it or the failure to so qualify has had or could reasonably be expected to have
a DBC Material Adverse Effect. DBC has delivered to the Company true and
complete copies of the certificate of incorporation and by-laws of each of the
DBC Companies, in each case as amended through the date of this Agreement.

         SECTION 3.02. Authority; Execution and Delivery; Enforceability. DBC
has full power and authority to execute this Agreement and the Ancillary
Agreements to which it is a party. Each of the DBC Companies has full power and
authority to consummate the DBC Contribution and the other transactions
contemplated hereby and thereby. The execution and delivery by DBC of this
Agreement and the Ancillary Agreements to which it is a party and the
consummation by the DBC Companies of the DBC Contribution and the other
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action. DBC has duly executed and delivered this Agreement
and each Ancillary Agreement to which it is a party, and this Agreement, and
each Ancillary Agreement to which it is a party, constitutes its legal, valid
and binding obligation, enforceable against it in accordance with its terms
except as enforcement may be limited by bankruptcy, insolvency or similar laws
affecting creditors' rights generally or equitable principles relating to or

relate in the conduct of the Business as presently conducted (the Liens
described in clauses (ii) and (iii) above are referred to collectively as
"Permitted Liens").

         SECTION 3.06.  Intellectual Property.

filing or issuance is necessary or appropriate for the conduct of the business
as presently conducted, (ii) one or more of the DBC Companies is the sole and
exclusive owner of, and DBC has the right to use, execute, reproduce, display,
perform, modify, enhance, distribute, prepare derivative works of and

as set forth in Schedule 3.06 and except for so-called "shrink-wrap" license
agreements relating to computer software licensed in the ordinary course of the
Business. The conduct of the Business as presently conducted does not violate,
conflict with or infringe the Intellectual Property of any other person. Except
as set forth in Schedule 3.06, (i) no claims are pending or, to the knowledge of
DBC, threatened, as of the date of this Agreement against any of the DBC
Companies by any person with respect to the ownership, validity, enforceability,
effectiveness or use in the Business of any Intellectual Property and (ii)
during the past three years DBC and its affiliates have not received any written

conduct of the Business violated any rights relating to Intellectual Property of
any person.

                  (c) All material Technology has been maintained in confidence
in accordance with protection procedures customarily used in the industry to
protect rights of like importance. All former and current members of management
and key personnel of DBC or any of its affiliates, including all former and
current employees, agents, consultants and independent contractors who have
contributed to or participated in the conception and development of material
Technology (collectively, "Personnel") either (i) have been party to a

property thereby arising or (ii) have executed appropriate instruments of
assignment in favor of one of the DBC Companies as assignee that have conveyed
to one of the DBC Companies full, effective and exclusive ownership of all
tangible and



                                       8
<PAGE>   12

intangible property thereby arising. No former or current Personnel have any

pending for any device, process, design or invention of any kind now used or
needed by any of the DBC Companies in the furtherance of the business, which

such assignment duly recorded in the United States Patent and Trademark Office.

                  (d) All Contributed Intellectual Property, as applicable, is
free of any "bugs" or "viruses" that could materially interfere with the
Company's use of such Intellectual Property.

obtained.

         SECTION 3.08. Personal Property. Each material item of tangible
personal property and interests therein, including all machinery, equipment,
furniture and vehicles, of any of the DBC Companies that constitute DBC Assets

material respects in accordance with the past practice of the Business and

none of such Permits will be subject to suspension, modification, revocation or
nonrenewal as a result of the execution and delivery of this Agreement or the

and the Company and each of their respective affiliates and each of their

("Losses"), as incurred (payable promptly upon written request), arising from,
in connection with or otherwise with respect to:

                             (i) any breach of any representation or warranty of
         DBC that survives the Closing and is contained in this Agreement, in
         any Ancillary Agreement or in any document delivered in connection
         herewith;

                            (ii) any breach of any covenant of DBC contained in
         this Agreement or in any Ancillary Agreement;

                           (iii) any Excluded DBC Liability;

                            (iv) the disclosure by any current or former
         Personnel of any proprietary information of DBC and its affiliates;

<PAGE>   22

         SECTION 6.03. Calculation of Losses. The amount of any Loss for which
indemnification is provided under this Article VI shall be net of any amounts
actually recovered by the indemnified party under insurance policies with
respect to such Loss and shall be (i) increased to take account of any net Tax
cost incurred by the indemnified party arising from the receipt of indemnity
payments hereunder (grossed up for such increase) and (ii) reduced to take
account of any net Tax benefit realized by the indemnified party arising from
the incurrence or payment of any such Loss. In computing the amount of any such
Tax cost or Tax benefit, the indemnified party shall be deemed to recognize all
other items of income, gain, loss, deduction or credit before recognizing any
item arising from the receipt of any indemnity payment hereunder or the
incurrence or payment of any indemnified Loss.

         SECTION 6.04. Termination of Indemnification. The obligations to
indemnify and hold harmless any party, (i) pursuant to Section 6.01(i) or
6.02(i), shall terminate when the applicable representation or warranty
terminates pursuant to Section 6.06 and (ii) pursuant to the other clauses of
Section 6.01 or 6.02 shall not terminate; provided, however, that such
obligations to indemnify and hold harmless shall not terminate with respect to
any item as to which the person to be indemnified shall have, before the
expiration of the applicable period, previously made a claim by delivering a
notice of such claim (stating in reasonable detail the basic of such claim)
pursuant to Section 6.05 to the party to be providing the indemnification.

         SECTION 6.05.     Procedures.

         (a) In order for a party (the "indemnified party"), to be entitled to
any indemnification provided for under this Agreement in respect of, arising out
of or involving a claim made by any person against the indemnified party (a
"Third Party Claim"), such indemnified party must notify the indemnifying party
in writing of the Third Party Claim promptly following receipt by such
indemnified party of written notice of the Third Party Claim; provided, however,
that failure to give such notification shall not affect the indemnification
provided hereunder except to the extent the indemnifying party shall have been
actually and materially prejudiced as a result of such failure. Thereafter, the
indemnified party shall deliver to the indemnifying party, promptly following
the indemnified party's receipt thereof, copies of all notices and documents
(including court papers) received by the indemnified party relating to the Third
Party Claim and not also addressed to the indemnifying party.

         (b) If a Third Party Claim is made against an indemnified party shall
be entitled to participate in the defense thereof and, if it so chooses, to
assume the defense thereof with counsel selected by the indemnifying party;
provided, however, that such counsel is not reasonably objected to by the
indemnified party. Should the indemnifying party so elect to assume the defense
of a Third Party Claim, the indemnifying party shall not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party assumes such defense, the indemnified party shall have the right to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the indemnifying party, it being
understood that the indemnifying party shall control such defense. The
indemnifying party shall be liable for the fees and expenses of counsel employed
by the indemnified party for any period during which the



                                       19
<PAGE>   23

indemnifying party has not assumed the defense thereof. If the indemnifying
party chooses to defend or prosecute a Third Party Claim, all the indemnified
parties shall cooperate in the defense or prosecution thereof. Such cooperation
shall include the retention and (upon the indemnifying party's request) the
provision to the indemnifying party of records and information that are
reasonably relevant to such Third Party Claim, and making employees available on
a mutually convenient basis to provide additional information and explanation of
any employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder. Whether or not
the indemnifying party assumes the defense of a Third Party Claim, the
indemnified party shall not admit any liability with respect to, or settle,
compromise or discharge, such Third Party Claim without the indemnifying party's
prior written consent (which consent shall not be unreasonably withheld). If the
indemnifying party assumes the defense of a Third Party Claim, the indemnified
party shall agree to any settlement, compromise or discharge of a Third Party
Claim that the indemnifying party may recommend and that by its terms obligates
the indemnifying party may recommend and that by its terms obligates the
indemnifying party to pay the full amount of the liability in connection with
such Third Party Claim, which releases the indemnified party completely in
connection with such Third Party Claim and that would not otherwise adversely
affect the indemnified party. Notwithstanding the foregoing, the indemnifying
party shall not be entitled to assume the defense of any Third Party Claim (and
shall be liable for the fees and expenses of counsel incurred by the indemnified
party in defending such Third Party Claim) if the Third Party Claim seeks an
order, injunction or other equitable relief or relief for other than money
damages against the indemnified party that the indemnified party reasonably
determines, after conferring with its outside counsel, cannot be separated from
any related claim for money damages. If such equitable relief or other relief
portion of the Third Party Claim can be so separated from that for money
damages, the indemnifying party shall be entitled to assume the defense of the
portion relating to money damages.

         (c) Other Claims. In the event any indemnified party should have a
claim against any indemnifying party under Section 6.01 or 6.02 that does not
involve a Third Party Claim being asserted against or sought to be collected
from such indemnified party, the indemnified party shall deliver notice of such
claim with reasonable promptness to the indemnifying party. The failure by any
indemnified party so to notify the indemnifying party shall not relieve the
indemnifying party from any liability that it may have to such indemnified party
under Section 6.01 or 6.02, except to the extent that the indemnifying party
demonstrates that it has been materially prejudiced by such failure. If the
indemnifying party does not notify the indemnified party within 10 calendar days
following its receipt of such notice that the indemnifying party disputes its
liability to the indemnified party under Section 6.01 or 6.02, such claim
specified by the indemnified party in such notice shall be conclusively deemed a
liability of the indemnifying party under Section 6.01 or 6.02 and the
indemnifying party shall pay the amount of such liability to the indemnified
party on demand or, in the case of any notice in which the amount of the claim
(or any portion thereof) is estimated, on such later date when the amount of
such claim (or such portion thereof) becomes finally determined. If the
indemnifying party has timely disputed its liability with respect to such claim,
as provided above, the indemnifying party and the indemnified party shall
proceed in good faith to negotiate a



                                       20
<PAGE>   24

resolution of such dispute and, if not resolved through negotiations, such
dispute shall be resolved by litigation in an appropriate court of competent
jurisdiction.

         SECTION 6.06. Survival of Representations. The representations and
warranties contained in this Agreement, in any Ancillary Agreement or in any
document delivered in connection herewith shall survive the Closing solely for
purposes of Article VI and shall terminate at the close of business five years
following the date hereof.

                                   ARTICLE VII

                               General Provisions

         SECTION 7.01. Assignment. This Agreement and the rights and obligations
hereunder shall not be assignable or transferable by CBS, DBC or the Company

however, that CBS may assign this Agreement and its rights and obligations
hereunder to any entity controlling, controlled by or under common control with,
CBS, or to any entity that acquires CBS by purchase of stock or by merger or
otherwise, or by acquiring all or substantially all of CBS's assets, provided
that any such assignee succeeds to all of the rights and is subject to all of
the obligations of CBS under this Agreement. Any attempted assignment in
violation of this Section 7.01 shall be null and void ab initio.

         SECTION 7.02. No Third-Party Beneficiaries. Except as provided in
Article VI, this Agreement is for the sole benefit of the parties hereto and
their permitted assigns and nothing herein expressed or implied shall give or be
construed to give to any person, other than the parties hereto and such assigns,
any legal or equitable rights hereunder.

         SECTION 7.03. Attorney Fees. A party in breach of this Agreement shall,
on demand, indemnify and hold harmless each other party for and against all
reasonable out-of-pocket expenses, including legal fees, incurred by such other
party by reason of the enforcement and protection of its rights under this
Agreement. The payment of such expenses is in addition to any other relief to
which such other party may be entitled.

         SECTION 7.04. Notices. All notices or other communications required or
permitted to be given hereunder shall be in writing and shall be delivered by
hand or sent, postage prepaid, by registered, certified or express mail or
reputable overnight courier service and shall be deemed given when so delivered
by hand, or if mailed, three days after mailing (one business day in the case of
express mail or overnight courier service), as follows:

                             CBS Contribution Terms


         1. CBS shall arrange for the placement of broadcast advertising and
promotion of the website operated by the Company in the media category or type
set forth in the Advertising and Promotion placement schedule set forth below.
The rate card value of all broadcast advertising and promotion provided
hereunder shall be based upon the average paid unit price, excluding barter, for
spots purchased during the specific CBS Television Network, CBS Owned and
Operated Television Station or CBS Owned and Operated Radio Station broadcast in
which the advertising or promotion occurs. Banner advertising on CBS Internet
sites shall have a rate card price equal to the average price paid by third
parties for banner advertising (excluding barter) during the month in which such
advertising is delivered less 20%. The total rate card value of banner
advertising delivered by CBS to the Company shall not exceed 5% per year of the
total advertising delivered by CBS to the Company during such year. CBS shall
not have to make any ad placements if the exigencies of time or current or
future contractual obligations, prevent or restrict CBS from doing so.

         2. CBS shall have the right to suspend and/or withdraw placement of
broadcast advertising and promotion (i) pending resolution of any claim covering
use by the Company of the tradename or trademark "Marketwatch" either alone or
in combination with any other mark and/or (ii) during such time as the Company
is enjoined from using the tradename or trademark "Marketwatch" on or in
connection with its website and has not renamed the website. The Company shall
rename its website within thirty (30) days following the issuance of any
injunction or the resolution of any claim which requires the Company to cease
using the tradename or trademark "Marketwatch" on or in connection with its
website (the "Cessation Event"), it being understood, however, that CBS shall
have the sole right and power to approve the substitute tradename and/or
trademark to be used. In the event that CBS fails to approve the substitute
tradename and/or trademark within the 30-day period prescribed, then the Members
will be deemed to have mutually agreed to terminate the Company on the 31st day
following the date of the Cessation Event as contemplated by Section 11.04(a)(i)
of the LLC Agreement.
