RLP agree that, notwithstanding the registration of the Demand Registrable Stock
owned by them, they will not, for a period of one year from the effective date
of said registration statement (the "Restricted Period"), sell any more shares
of Demand Registrable Stock, in the aggregate, than Prochnow would be entitled
to sell during the Restricted Period in compliance with Rule 144(e)(1) under the
Act). Notwithstanding the foregoing, such limitation on the sale of Demand
Registrable Stock during the Restricted Period shall not apply to any
organization exempt under Section 501(c)(3) of the Internal Revenue Code of

applicable to contracts made and to be performed entirely within such State.
This Agreement may be executed in counterparts and by the parties hereto in
separate counterparts, each of which shall constitute an original and all of
which together shall constitute one and the same agreement. This Agreement
supersedes any prior understanding or agreement, written or oral, between or
among the parties hereto (or any of them) relating to the subject matter hereof.
However, except as amended hereby, the Registration Rights Agreement and the

                     NON-NEGOTIABLE SECURED PROMISSORY NOTE

               FOR VALUE RECEIVED, Richard L. Prochnow (the "Maker"), hereby
promises to pay to the order of Cross Media Marketing Corporation (f/k/a

from such sale to reduce the amount outstanding on this Note; provided, however,
that the aggregate of all such payments in connection with sales of Common Stock

               If any payment on this Note is not made when due, such payment
and any outstanding amount on this Note shall thereafter bear interest at a rate
of 10% per annum until the amount not paid and accrued and unpaid interest is
paid in full.

               All payments on this Note shall be made in such currency of the
United States as at the time of payment shall be legal tender for the payment of
public and private debts.

               This Note evidences indebtedness incurred pursuant to the terms
of that certain Stock Purchase Agreement of June 9, 1999 between Maker and Cross
Media Marketing (the "Purchase Agreement"). Cross Media Marketing and the Maker
also entered into a Stock and Partnership Interest Pledge Agreement dated June

hereof (as so amended, the "Pledge Agreement") providing, among other things,
for the securing of this Note by a pledge of the Pledged Collateral (as defined
in the Pledge Agreement). To the extent applicable, the provisions of the
Purchase Agreement and/or the Pledge Agreement (including, without limitation,
the provisions of Section 6.1 of the Purchase Agreement) are incorporated herein
by this reference.

               If any of the following events (each, an "Event of Default")
shall occur:

               (a) the Maker shall default in the payment of any part of the
principal or interest on this Note when the same shall become due and payable,
whether at maturity, by acceleration or otherwise.

               (b) the Maker shall (i) become insolvent or be unable, or admit
in writing its inability, to pay its debts as they mature; (ii) make a general
assignment for the benefit of creditors; (iii) be adjudicated as bankrupt or
insolvent or file a voluntary petition in bankruptcy; (iv) file a petition or an
answer seeking an arrangement with creditors to take advantage of any insolvency
law; or (v) file an answer admitting to the material obligations or consent to,
or default in answering, or fail to have dismissed within 60 days after the
filing thereof, a petition filed against it in any bankruptcy or insolvency
proceeding; or

               (c) any breach of the Maker's obligations under the Pledge
Agreement shall have occurred and be continuing or any representation or
warranty made under Section 4.3 of the Pledge Agreement shall be false in any
material respect,

               then, the holder of this Note may at any time by written notice
to the Maker, declare the entire unpaid principal of and the interest accrued on
this Note through the date of such Event of Default to be forth with due and
payable, without other notices or demands of any kind, all of which are hereby
waived by the Maker; provided that if an Event of Default occurs pursuant to
paragraph (b) above, the entire unpaid principal and the interest accrued on
this Note shall be come automatically due and payable without any notice, demand
or other action by the holder.

<PAGE>

               The Maker agrees to pay to the holder hereof all reasonable
expenses incurred by such holder, including reasonable attorneys' fees, in
enforcing and collecting this Note.

               The Maker hereby forever waives presentment, demand, presentment
for payment, protest, notice of protest, notice of dishonor of this Note and all
other demands and notices in connection with the delivery, acceptance,
performance and enforcement of this Note.

               This Note shall be paid without deduction by reason of any
set-off, defense or counterclaim of the Maker.

               This Note shall be governed by and construed in accordance with
the laws of the State of Georgia, without giving effect to conflicts of law
principles thereof.

               This Note is non-negotiable and shall not be transferred or
assigned by Cross Media Marketing except by operation of law or as provided in
the Purchase Agreement. Any attempted assignment of this Note by Cross Media
Marketing except by operation of law or as provided in the Purchase Agreement
shall be deemed void. This Note amends and replaces that certain Amended
Non-Negotiable Secured Promissory Note dated January 28, 2000 executed by Maker
in favor of Holder.
