                             AMENDED PROMISSORY NOTE

Amount of $287,575.25                                       As of April 1, 2001

         FOR VALUE RECEIVED, Long Distance Direct Holdings, Inc. ("Maker"), a
Nevada corporation, does hereby promise to pay to the order of PowerChannel
Holdings, Inc. ("Holder"), a Delaware corporation having an address at 20
Squadron Blvd., Suite 210, New City, NY 10956, the principal sum of Two Hundred
Eighty-Seven Thousand Five Hundred Seventy-Five Dollars and Twenty-Five Cents
($287,575.25), with simple interest thereon at the rate of seven and one-half
percent (7.5%) per annum, until maturity. The principal and all accrued interest
due under this Note shall be paid in full on or before December 31, 2001 (the
"Maturity Date"). This note amends and replaces the Promissory Note dated
December 21, 2000 by the Maker in favor of the Holder (the "Original Note"). In
consideration for extension of the Maturity Date from June 30, 2001 to December
31, 2001, Maker agrees to pay Holder an amount of Ten Thousand Dollars ($10,000)
which amount is has been added to the face value of the Original Note.

         Holder has advanced funds to Maker at various times and in various
amounts, all as set forth on the Schedule appearing on the signature page
hereof. Interest shall accrue only on the amount of principal actually
outstanding from time to time.

         The indebtedness evidenced by this Note may be prepaid in whole or in
part at any time without penalty or premium. Any and all such prepayments shall
be paid with interest on the amount being prepaid through the date of such
prepayment.

         If Maker fails to repay this Note in full, along with accrued interest,
on or prior to the Maturity Date, Maker undertakes that it shall deliver to
Holder the number of the shares of Holder's common stock owned by Maker, with
each share being valued at $1.00 per share, equivalent to the principal amount,
plus accrued interest, not repaid. Maker consents to the entry in the Holder's
share registry of a stop-transfer notation on 300,000 shares of Holder's common

                                       1

stock owned by Maker and to the cancellation of such shares in the event this
Note is not paid as agreed.

         The outstanding principal amount of this Note shall be accelerated and
shall become immediately due and payable upon the occurrence of any of the
following events:

         (i)   Maker shall file a petition or otherwise seek relief from
               creditors in any proceeding under any bankruptcy, reorganization,
               moratorium or similar laws for the relief or benefits of
               creditors (such laws, collectively, "Bankruptcy Laws");

         (ii)  a petition shall be filed against Maker in any proceeding under
               any Bankruptcy Laws and either (a) Maker shall consent thereto or
               acquiesce therein or (b) the same shall not be discharged or
               reversed within thirty (30) days;

         (iii) a receiver, liquidator, sequestrator or similar official shall be
               appointed by any court of competent jurisdiction over Maker or
               any substantial portion of its business and assets;

         (iv)  Maker shall admit in writing its inability, or shall become
               unable, to pay its debts generally as they become due.

         Presentment for payment, demand, protest and notice of demand, notice
of dishonor and notice of nonpayment and all other notices are hereby waived by
Maker. No failure to accelerate the debt evidenced hereby by reason of default
hereunder, acceptance of a past due installment, or indulgences granted from
time to time shall be construed (1) as a novation of this Note or as a
restatement of the indebtedness evidenced hereby or as a waiver of such right of
acceleration or of the right of the Holder thereafter to insist upon strict
compliance with the terms of this Note, or (2) to prevent the exercise of such
right of acceleration or any other right granted hereunder or by applicable law;
and Maker hereby expressly waives the benefit of any statute or rule of law or
equity now provided, or which may hereafter be provided, which would produce a
result contrary to or in conflict with the foregoing. No extension of the time
for the payment of this Note or any installment due hereunder, made by agreement
with any person now or hereafter liable for the payment of this Note shall
operate to release, discharge, modify, change or affect the original

                                       2

<PAGE>

liability of the Maker under this Note, either in whole or in part, unless the
Holder agrees otherwise in writing. This Note may not be changed orally, but
only by an agreement in writing signed by the party against whom enforcement of
any waiver, change, modification or discharge is sought.

                  Maker hereby waives and renounces for itself, its heirs,
successors and assigns, all rights to the benefits of any statute of
limitations, any moratorium, reinstatement, marshaling, forbearance, valuation,
stay, extension, redemption, appraisement and exemption now provided, or which
may hereafter by provided, by the Constitution and laws of the United States of
America and of any state thereof, against the enforcement and collection of the
obligations evidenced by this Note.

         The terms and provisions of this Promissory Note are severable, and if
any term or provision shall be determined to be superseded, illegal, invalid or
otherwise unenforceable in whole or in part pursuant to applicable law by a
court of competent jurisdiction, that determination shall not in any manner
impair or otherwise affect the validity, legality or enforceability of that term
or provision in any other jurisdiction or any of the remaining terms and
provisions of this Note in any jurisdiction.

         No delay or failure on the part of Holder to exercise any power or
right given under this Note shall operate as a waiver of the power or right, and
no course of conduct by Holder shall be deemed to amend or modify this Note or
to affect the meaning or interpretation of any provision hereof. No amendment or
other modification of this Note shall be effective except to the extent
expressly set forth in writing signed by Maker and Holder.

         Any notice required or permitted hereunder shall be in writing and
shall be delivered personally, by overnight courier service or by both
registered or certified mail, return receipt requested, and first class mail,
addressed to the maker at its corporate offices or to the holder at its address
set forth above or at such other more recent address for such party as notice
has been given, and any notice so given shall be deemed received when so
personally delivered, one

business day after being so sent by overnight courier service or three (3)

         This Note shall be governed by, and interpreted and enforced in
accordance with, the internal laws of the State of New York applicable to
contracts executed, and to be wholly performed, within the State of New York.
Any action brought by either party against the other concerning this Note shall

                                                              New York, New York

         ON DEMAND as set forth herein, for value received, ALLOY ONLINE, INC.,
a Delaware corporation ("Maker"), promises to pay to the order of ALAN M.
WEISMAN ("Holder"), at the address of the Holder at 1800 Sherman Ave., Suite
400, Evanston, IL 60201, or at such other place or places or to such other party
or parties as the Holder may from time to time designate, the Principal Amount
as determined below, without interest; provided, that if this Note is not paid
in full upon demand for payment thereof given in accordance with the provisions
hereof, interest on the unpaid balance shall thereafter be payable on demand at
an interest rate per annum equal to ten percent (10%) per annum.

         This Note is issued pursuant to the provisions of that certain
Agreement and Plan of Reorganization, dated as of July 3, 2001 (the
"Reorganization Agreement"), by and among Maker, CASS Communications, Inc., an
Illinois corporation, and Holder. Pursuant to terms and conditions set forth in
the Registration Rights Agreement of even date herewith between Maker and
Holder, Maker has agreed to use all commercially reasonable efforts to file a
Registration Statement on Form S-3 or any successor thereto for a public
offering of all of the Restricted Stock (as such term is defined in the
Registration Rights Agreement (the "Initial Registration") within thirty (30)
days of the consummation of the transactions contemplated by the Reorganization
Agreement, and to use all commercially reasonable efforts to cause the same to
be declared effective by the Securities Exchange Commission.

         Holder shall have the ability to demand payment of the final Principal
Amount of this Note, if any, only during the period beginning on the date (the
"Anniversary Date") which is exactly four (4) months after the date of the
declaration of effectiveness of the Initial Registration by the Securities and
Exchange Commission (the "Commencement Date") and ending at 5:00 p.m. local New
York, New York time on the date which is exactly sixty (60) days after the
Anniversary Date (the "Expiration Date"). The Principal Amount of this Note at
any time outstanding shall be determined as follows: On the date hereof, this
Note shall have a contingent Principal Amount of $10,000,000. Thereafter, on the
date that is exactly one (1) month after the Commencement Date and on each
subsequent monthly anniversary date thereafter (each, a "Monthly Anniversary
Date") up to and including the Anniversary Date, Maker shall calculate a monthly
balance (each, a "Monthly Balance"), which shall be equal to the product of (x)
the average closing sale price of the common stock, par value $0.01 per share,
of Maker (the "Common Stock") as quoted on the NASDAQ National Market System for
each of the trading days in such monthly period multiplied by (y) 221,700;
provided, that if the Common Stock is not listed for trading on the NASDAQ
National Market System for all or any of the days in such monthly period, the
average closing sale price of the Common Stock on any such day shall be equal to
the average of the closing bid and asked prices of the Common Stock on such day
as quoted in the Over-The-Counter Market Summary or the last reported sale price
of the Common Stock on such day on the principal exchange or market on which the
Common Stock is then listed for trading, whichever is applicable.

         At the same time as it calculates each Monthly Balance, Maker shall
calculate the remaining contingent Principal Amount of this Note, which shall be
equal, as of any date, to $10,000,000 less the sum of the Monthly Balances
determined through such date, and shall deliver a copy of each such

<PAGE>

calculation to Holder. Unless this Note earlier shall have been deemed satisfied
and cancelled in accordance with the provisions set forth below, promptly after
the Anniversary Date Maker shall deliver to Holder Maker's calculation of the
final Principal Amount. Maker's calculation of the Monthly Balances and the
contingent and final Principal Amounts shall be final and binding on Maker and
Holder absent manifest error.

         This Note shall be deemed to have been satisfied in full and shall have
no further force or effect after the first to occur of (A) the Expiration Date,
if Holder shall not have previously made a demand for payment hereunder, (B) the
date on which the then current Principal Amount is less than or equal to zero
($0), and (C) the first date prior to the Anniversary Date on which Holder shall
have received (or be deemed to have received pursuant to next succeeding
paragraph) gross proceeds of $10,000,000 or more from Sales (as defined herein)
by Holder of Common Stock issued by Maker pursuant to the provisions of the
Reorganization Agreement. Upon the expiration of this Note pursuant to the
provisions of this paragraph, Holder shall, at the request of Maker, deliver
this Note to Maker for cancellation.

         In order that Maker may maintain an accurate record of the gross
proceeds received by Holder from Sales of Common Stock, Holder covenants to
deliver to Maker written notice of the date, number of shares and gross Sales
proceeds received upon any Sales of Common Stock by Holder on or prior to the
Anniversary Date within two (2) business days after consummation of any such
Sale. For purposes hereof, a "Sale" shall mean (A) completion of any agreement
to sell any Common Stock, (B) entrance into any contract to sell any Common
Stock prior to the Anniversary Date which has a closing date with respect to all
or any portion of the Common Stock covered thereby after the Anniversary Date,
or (C) a pledge or other disposition of, or the entrance into any agreement or
transaction which is designed to, or might reasonably be expected to, result in
the disposition (whether by actual disposition or effective economic disposition
due to cash settlement or otherwise) of, shares of Common Stock, including,
without limitation, by means of a gift or other transaction for no
consideration; provided, however, that any such gift or conveyance to a family
member of Holder or to an estate planning vehicle of any sort shall not be
deemed a "Sale" for purposes of this Note. Notwithstanding the foregoing, if any
Sale shall occur (i) in a manner other than pursuant to an arms' length
transaction with a party that is unrelated to and otherwise unaffiliated with
Holder and (ii) at a price that is less than the average closing sale price of
the Common Stock as quoted on the NASDAQ National Market System for each of the
five (5) trading days preceding the date of such Sale (the "Average Sales
Price"), then, for purposes of the provisions of subsection (ii) of clause (C)
above, such Sale shall be deemed to have occurred at the Average Sales Price.

         Maker may voluntarily prepay this Note, in whole or in part, at any
time and from time to time without penalty.

         Maker will pay on demand, without limitation, all reasonable attorneys'
fees, out-of-pocket expenses reasonably incurred by the Holder's attorneys and
all costs reasonably incurred by the Holder, including, without limitation costs
and expenses associated with travel on behalf of the Holder, which costs and
expenses are directly or indirectly related to the protection or enforcement of
any of the Holder's rights against Maker or any endorser or guarantor of this
Note (whether or not suit is instituted by or against the Holder) following a
breach by Maker of any of its obligations hereunder.

         No delay or omission on the part of the Holder in exercising any right
hereunder shall operate as a waiver of such right or of any other right of the
Holder, nor shall any delay, omission or waiver on any

                                      -2-

<PAGE>

one occasion be deemed a bar to or waiver of the same or any other right on any
future occasion. Maker and every endorser or guarantor of this Note, regardless
of the time, order or place of signing, waive presentment, demand, protest and
notices of every kind and assents to any extension or postponement of the time
or terms of payment hereunder or any other indulgence, to any substitution,
exchange or release of collateral, and to the addition or release of any other
party or person primarily or secondarily liable.

         All amounts hereunder shall automatically become immediately due and
payable if Maker commences or has commenced against it any bankruptcy or
insolvency proceeding.

         None of the terms or provisions of this Note may be excluded, modified,
or amended except by a written instrument duly executed on behalf of the Holder
expressly referring hereto and setting forth the provisions so excluded,
modified or amended.

         The term "Holder" as used in this Note includes the Holder's heirs,
personal representatives, executors and assigns. This Note shall be binding upon
Maker and its successors and assigns. Notwithstanding the foregoing, neither
this Note nor any of the obligations hereunder may be assigned by Maker without
the prior written consent of Holder, which may by granted or withheld in
Holder's sole discretion.

         This Note contains the entire agreement between the Holder and Maker
with respect to the matters covered hereby, and supersedes every course of
dealing, other conduct, oral agreement and representation previously made by the
Holder. Each provision of this Note shall survive until all amounts due are
indefeasibly paid in full to the Holder, and shall be interpreted as consistent
with existing law, and shall be deemed amended to the extent necessary to comply
with any conflicting law. If a Court deems any provision invalid, the remainder
of this Note shall remain in full force and effect.

         ALL RIGHTS AND OBLIGATIONS HEREUNDER SHALL BE GOVERNED BY THE LAWS OF
THE STATE OF DELAWARE, WITHOUT REGARD TO ITS CONFLICTS OF LAWS PROVISIONS.

         MAKER AND HOLDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ALL
RIGHTS TO TRIAL BY JURY IN ANY LEGAL ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT
BY THE HOLDER AGAINST MAKER ON ANY MATTER WHATSOEVER ARISING OUT OF, IN
CONNECTION WITH OR RELATED TO THIS NOTE.

         THIS NOTE IS A DEMAND NOTE DUE AND OWING IMMEDIATELY, WITHOUT PRIOR
DEMAND OF THE HOLDER, AND IMMEDIATE ACTION TO ENFORCE ITS PAYMENT MAY BE TAKEN
AT ANY TIME WITHOUT NOTICE.
