     Section 10.08. Successors And Assigns; Registration. (a) The provisions of

hereto and their respective successors and assigns (including any transferee of

its rights under this Agreement without the prior written consent of the
Required Holders.

     (b) Either of the Purchasers may at any time assign or transfer all, or a
proportionate part of all of its rights and obligations under this Agreement and
the Notes only with the prior written consent of the Company and each other
Purchaser (each, a "NON-ASSIGNING PURCHASER"), which consent shall not be
unreasonably withheld or delayed; provided that the consent of the Company and
the Non-Assigning Purchasers shall not be required for such assignments or
transfers (i) to an Affiliate of a Purchaser or (ii) to another Purchaser.

assignee of any Note and, in the event of such transfer or assignment, the
rights and privileges herein conferred upon the assigning Purchaser shall
automatically extend to and be vested in such transferee or assignee, all such
to the terms and conditions hereof.

     (c) Upon any assignment of any Note, the assigning Purchaser shall
surrender its Note to the Company for exchange or registration of transfer, and
the Company will promptly execute and deliver in exchange therefor a new Note or
Note of the same tenor, and registered in the name of the assignor Purchaser (if
less than all of such Purchaser's Notes are assigned) and the name of the
assignee Purchaser.
 
     (d) The Company shall maintain a register (the "NOTE REGISTER") of the
Purchasers and all assignee Purchasers that are the holders of all the Notes
issued pursuant to this Agreement. The Company will allow any Purchaser to
inspect and copy such list at the Company's principal place of business during
normal business hours. Prior to the due presentment for registration of transfer
of any Note, the Company may deem and treat the Person in whose name a Note is
registered as the absolute owner of such Note for the purpose of receiving
payment of principal of and premium and interest on such Note and for all other
purposes whatsoever, and the Company shall not be affected by notice to the
contrary.

     (e) Each Purchaser (including any assignee Purchaser at the time of such
assignment) represents that it (i) is acquiring its Note solely for investment
purposes and not with a view toward, or for sale in connection with, any
distribution thereof, (ii) has received and reviewed such information as it
deems necessary to evaluate the merits and risks of its investment in the Notes,
(iii) is an "accredited investor" within the meaning of Rule 501(a) under the
Securities Act, and (iv) has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of its
investment in the Notes, including a complete loss of its investment.

     (f) Each Purchaser understands that the Notes are being offered only in a
transaction not involving any public offering within the meaning of the
Securities Act, and that, if in the future such Purchaser decides to resell,
pledge or otherwise transfer any of the Notes, such Notes may be resold, pledged
or transferred only (i) to the Company, (ii) to a person who such Purchaser
reasonably believes is a qualified institutional buyer that purchases for its
own account or for the account of a qualified institutional buyer to whom notice
is given that such resale, pledge or transfer is being made in reliance on Rule
144A under the Securities Act, or (iii) pursuant to an exemption from
registration under the Securities Act.

     (g) Each Purchaser understands that the Notes will, unless otherwise agreed
by the Company and the holder thereof, bear a legend to the following effect:

     THIS SECURITY IS NOT BEING REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "SECURITIES ACT").  THE HOLDER HEREOF, BY PURCHASING THIS SECURITY,
AGREES FOR THE BENEFIT OF THE ISSUER THAT THIS SECURITY MAY BE RESOLD, PLEDGED

is surrendered by the Purchaser with respect thereto to the Company, or if any
Purchaser claims that its Note has been lost, destroyed or wrongfully taken, the
Company shall execute and deliver to such Purchaser a replacement Note, upon 
the affidavit of such Purchaser attesting to such loss, destruction or wrongful
taking with respect to such Note and such lost, destroyed, mutilated,
surrendered or wrongfully taken Note shall be deemed to be canceled for all
purposes hereof.
                                       34

Such affidavit shall be accepted as satisfactory evidence of the loss, wrongful
taking or destruction thereof and no indemnity shall be required as a condition
of the execution and delivery of a replacement Note. Any costs and expenses of
the Company in replacing any such Note shall be for the account of such
Purchaser.

Documents (including the Exhibits and Schedules hereto and thereto) are included
for convenience of reference only and shall not be given any substantive effect.

     Section 10.11. Confidentiality. In handling any confidential information of
the Company or any of its Subsidiaries, the Purchasers shall exercise the same
degree of care that it exercises with respect to its own proprietary information
of the same types to maintain the confidentiality of any non-public information
thereby received or received pursuant to this Agreement except that disclosure
of such information may be made (i) to the agents, employees, Subsidiaries or
Affiliates of such Person in connection with its present or prospective business
relations with the Company and its Subsidiaries arising out of the Financing
Documents, but only to the extent that each such agent, employee, Subsidiary or
Affiliate has been directed to maintain the confidentiality of such information
in accordance with the provisions of this Section 10.11, (ii) to prospective
transferees or purchasers of any interest in the Notes, provided that they have
agreed to be bound by the provision of this Section 10.11, (iii) as required by
law, regulations, rule, request or order, subpoena, judicial order or similar
order and in connection with any litigation, and (iv) as may be required in
connection with the examination, audit or similar investigation of such Person.

purpose except in connection with the transactions and agreements contemplated
by the Financing Documents. Confidential information shall include only such
information identified as such in writing at the time provided to the Purchasers
or upon written notice to the Purchasers at any time thereafter and shall not
include information that either: (i) is in the public domain, or becomes part of
the public domain after disclosure to such Person through no fault of such
Person or (ii) is disclosed to such Person by a third party, provided the
Purchasers do not have actual knowledge that such third party is prohibited from
disclosing such information.

amount is paid in full at 14% per annum (and until the date such overdue amount

     This Note is being delivered pursuant to a Note Purchase Agreement, dated

Note Purchase Agreement, which among other things, contains provisions for the
acceleration of the maturity hereof upon the happening of certain events and for
the amendment or waiver of certain provisions of the Note Purchase Agreement,
all upon the terms and conditions therein specified.

     1. Certain Definitions. As used herein, the following terms have the
following meanings:

     "CLOSING PRICE" shall mean, on any day, (i) the closing price of the Common
Stock (or any other security for which a closing price must be determined) on a
national securities exchange or as quoted on the Nasdaq National Market on such
day, as reported by the Wall Street Journal or (ii) if the Common Stock (or any
such other security) is quoted on the Nasdaq National Market but no sale occurs
on such day, the average of the closing bid and asked prices of the Common Stock
(or any such other security) on the Nasdaq National Market on such day, as
reported by the Wall Street Journal or (iii) if the Common Stock (or any such
other security) is not so listed or quoted, the average of the closing bid and
asked prices of the Common Stock (or any such other security) in the U.S. over-
the-counter market or (iv) if no such trading market is readily available, the
fair market value of the Common Stock (or any such other security) as determined
in accordance with Section 5(b) hereof.

     "CURRENT MARKET PRICE" of the Common Stock means the average of the daily
Closing Prices of the Common Stock for the five consecutive trading days
selected by the board of directors commencing not more than 20 trading days
before, and ending not later than the date immediately preceding the record date
fixed in connection with such event or, if there is no record date, the date of
such event; provided, that the Current Market Price of the Common Stock in
connection with a Spin-Off shall mean the average of the daily Closing Prices of

                                       2
<PAGE>
 
the Common Stock for the same five consecutive trading days used to determine
the Fair Market Value of the securities being distributed in such Spin-Off.

     "FAIR MARKET VALUE" of the securities to be distributed to the holders of
the Common Stock in connection with a Spin-Off shall mean the average of the
daily Closing Prices of such securities for a five consecutive trading day
period selected by the board of directors during the period beginning on the
first day of trading of such securities after the effectiveness of such Spin-Off
and ending not later than 20 days after the effectiveness of the Spin-Off.

     All capitalized terms used but not otherwise defined herein shall have the
meaning ascribed to such terms in the Note Purchase Agreement.

     2. Security.

     The Purchaser's right to payment pursuant to the terms of this Note shall
be secured to the extent and on the terms and conditions set forth in the
Security Agreement, and the terms and provisions of the Security Agreement are
incorporated herein by reference.

     3. Payment.

     Principal Payments on each Principal Payment Date and Interest on each
Interest Payment Date shall be made by bank cashier's check payable to the
Purchaser at the Purchaser's principal address set forth in Section 10.04 of the
Note Purchase Agreement (or at such other place as the Purchaser hereof shall
notify the Company in writing) or, if the Purchaser so specifies, by written
notice to the Company given not less than two Business Days prior to the
Principal Payment Date or the Interest Payment Date, as the case may be, by bank
wire transfer, in immediately available funds, to the account so specified, in
lawful money of the United States of America; provided that, at the election of
the Company, so long as the Company is listed on the Nasdaq National Market, up
to [one-sixth - CFS Note]/[100% - CMGI Note] of the amount of Interest due on
any Interest Payment Date through and including the Interest Payment Date in
December [2003 -CFS Note]/[2007-CMGI Note] may be paid in shares of Common
Stock.  The number of shares of Common Stock to be issued in payment of the
Interest due on such Interest Payment Date shall equal the amount of such
Interest to be paid in Common Stock divided by the average of the Closing Prices
per share of the Common Stock on the five consecutive trading days ending on the
trading day immediately preceding such Interest Payment Date.  If any Principal
Payment Date or any Interest Payment Date occurs on a date that is not a
Business Day, then the Principal Sum or Interest then due shall be paid on the
next succeeding Business Day.
