                  MASTER LOAN AND SECURITY AGREEMENT NO. 10220

DEBTOR: MessageMedia, Inc.    SECURED PARTY: Wells Fargo Equipment Finance, Inc.
        6060 Spine Road                      530 Fifth Avenue
        Boulder, CO 80301                    New York, NY 10036

In consideration of the mutual covenants set forth herein, the above named
Debtor and the above named Secured Party hereby enter into this Master Loan and
Security Agreement and agree to the terms and conditions set forth herein. Each
Loan Schedule which may be executed by Debtor and Secured Party from time to
time pursuant to this Master Loan and Security Agreement shall be deemed to be a
separate loan transaction incorporating all of the terms and conditions of this
Master Loan and Security Agreement. References in this Master Loan and Security
Agreement to "Agreement", "hereunder" and "herein" shall mean a Loan Schedule
which incorporates this Master Loan and Security Agreement.

     1. LOAN SCHEDULES. Debtor shall evidence its agreement to enter into each
Agreement incorporating the terms hereof by executing and delivering to Secured
Party a Loan Schedule in the form annexed hereto as Exhibit 1. Debtor's
execution of a Loan Schedule shall obligate Debtor to make all of the payments
set forth in the Schedule of Obligations as set forth in the Loan Schedule. The
Loan Schedule shall set forth the amount of the Loan, the Term of the Loan, the
number of payments to be made and the amount and dates upon which such payments
are due. The Loan Schedule shall also set forth the Time Balance which means the
aggregate amount of all payments which are payable under the Agreement evidenced
by such Loan Schedule. Secured Party shall have no obligation to enter into or
accept any Loan Schedule and no Loan Schedule shall be binding upon Secured
Party until accepted by Secured Party which acceptance shall be evidenced only
by the execution of such Loan Schedule by Secured Party.

     2. GRANT OF SECURITY INTEREST. Debtor hereby grants to Secured Party a
security interest in the personal property referred to and/or described in each
Loan Schedule (hereinafter with all renewals, substitutions and replacements
and all parts, repairs, improvements, additions and accessories incorporated
therein or affixed thereto referred to as the "Equipment"), together with any
and all proceeds thereof and any and all insurance policies and proceeds with
respect thereto.

     3. OBLIGATIONS SECURED. The aforesaid security interest is granted by
Debtor as security for (a) the payment of the Time Balance (as set forth in the
Loan Schedule) and the payment and performance of all other indebtedness and
obligations now or hereafter owing by Debtor to Secured Party, of any and every
kind and description under the Agreement evidenced by such Loan Schedule, and
any and all renewals and extensions of the foregoing, and all interest, fees,
charges, expenses and attorneys' fees accruing or incurred in connection with
any of the foregoing (all of which Time Balance, indebtedness and obligations
are hereinafter referred to as the "Liabilities") and (b) the payment and
performance of all other indebtedness and obligations now or hereafter owing by
Debtor to Secured Party, of any and every kind and description, howsoever
arising or evidenced including without limitation those arising under other Loan
Schedules, (all of which indebtedness and obligations are hereinafter referred
to as the "Other Liabilities"). Subject to Paragraph 16, any nonpayment of any
installment or other amounts within ten (10) days of when due hereunder shall
result in the obligation on the part of Debtor promptly to pay also an amount
equal to five percent (5%), (or the maximum rate permitted by law, whichever is
less) of the installment or other amounts overdue.

     4. DISCLAIMER OF WARRANTIES. DEBTOR ACKNOWLEDGES THAT SECURED PARTY MAKES
NO WARRANTIES, EXPRESS OR IMPLIED, IN RESPECT OF THE EQUIPMENT, INCLUDING,
WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY
PARTICULAR PURPOSE. Secured Party shall not be liable to Debtor for any loss,
damage or expense of any kind or nature caused, directly or indirectly, by any
Equipment secured hereunder or the use or maintenance thereof or the failure of
operation thereof, or the repair, service or adjustment thereof, or by any delay
or failure to provide any such maintenance, repairs, service or adjustment, or
by any interruption of service or loss of use thereof or for any loss of
business howsoever caused. The Equipment shall be shipped directly to Debtor by
the supplier thereof and Debtor agrees to accept such delivery. No defect or
unfitness of the Equipment, nor any failure or delay on the part of the
manufacturer or the shipper of the Equipment to deliver the Equipment or any
part thereof to Debtor, shall relieve Debtor of the obligation to pay the Time
Balance or any other


<PAGE>   2

obligation under this Agreement. Secured Party shall have no obligation under
this Agreement in respect of the Equipment and shall have no obligation to
install, erect, test, adjust or service the Equipment. Secured Party agrees, so
long as there shall not have occurred or be continuing any Event of Default
hereunder or event which with lapse of time or notice, or both, might become an
Event of Default hereunder, that Secured Party will permit Debtor to enforce in
Debtor's own name at Debtor's sole expense any supplier's or manufacturer's
warranty or agreement in respect of the Equipment to the extent that such
warranty or agreement is assignable.

     5. ASSIGNMENT. Any transaction evidenced by a Loan Schedule shall be
assignable by Secured Party, and by its assigns, without the consent of Debtor,
but Debtor shall not be obligated to any assignee except upon written notice of
such assignment from Secured Party or such assignee. The obligation of Debtor to
pay and perform the Liabilities to such assignee shall be absolute and
unconditional and shall not be affected by any circumstance whatsoever, and such
payments shall be made without interruption or abatement notwithstanding any
event or circumstance whatsoever, including, without limitation, the late
delivery, non-delivery, destruction or damage of or to the Equipment, the
deprivation or limitation of the use of the Equipment, the bankruptcy or
insolvency of Secured Party or Debtor or any disaffirmance of this Agreement by
or on behalf of Debtor and notwithstanding any defense, set-off, recoupment or
counterclaim or any other right whatsoever, whether by reason of breach of this
Agreement or of any warranty in respect of the Equipment or otherwise which
Debtor may now or hereafter have against Secured Party, and whether any such
event shall be by reason of any act or omission of Secured Party (including,
without limitation, any negligence of Secured Party) or otherwise; provided,
however, that nothing herein contained shall affect any right of Debtor to
enforce against Secured Party any claim which Debtor may have against Secured
Party in any manner other than by abatement, attachment or recoupment of,
interference with, or set-off, counterclaim or defense against, the
aforementioned payments to be made to such assignee. Debtor's undertaking herein
to pay and perform the Liabilities to an assignee of Secured Party shall
constitute a direct, independent and unconditional obligation of Debtor to said
assignee. Said assignee shall have no obligations under this Agreement or in
respect of the Equipment and shall have no obligation to install, erect, test,
adjust or service the Equipment. Debtor also acknowledges and agrees that any
assignee of Secured Party's interest in this Agreement shall have the right to
exercise all rights, privileges and remedies (either in its own name or in the
name of Secured Party) which by the terms of this Agreement are permitted to be
exercised by Secured Party.

     6. DAMAGE TO OR LOSS OF THE EQUIPMENT; REQUISITION. Debtor assumes and
shall bear the entire risk of loss or damage to the Equipment from any and
every cause, whatsoever. No loss or damage to the Equipment or any part thereof
shall affect any obligation of Debtor with respect to the Liabilities and this
Agreement, which shall continue in full force and effect. Debtor shall advise
Secured Party in writing promptly of any item of Equipment lost or damaged and
of the circumstances and extent of such damage. If the Equipment is totally
destroyed, irreparably damaged, lost, stolen or title thereto shall be
requisitioned or taken by any governmental authority under the power of eminent
domain or otherwise, Debtor shall, in the reasonable discretion of Debtor so
long as no Event of Default shall have occurred under this Agreement, otherwise
at the option of Secured Party, replace the same with like equipment in good
repair, condition and working order, or pay to Secured Party all Liabilities due
and to become due, less the net amount of the recovery, if any, actually
received by Secured Party from insurance or otherwise for such destruction,
damage, loss, theft, requisition or taking. Whenever the Equipment is destroyed
or damaged and, in the reasonable discretion of Debtor so long as no Event of
Default shall have occurred under this Agreement, otherwise in the sole
discretion of Secured Party, such destruction or damage can be repaired, Debtor
shall, at its expense, promptly effect such repairs as Secured Party shall deem
necessary for compliance with clause (a) of paragraph 8 below. Any proceeds of
insurance received by Secured Party with respect to such reparable damage to the
Equipment shall, at the election of Secured Party, be applied either to the
repair of the Equipment by payment by Secured Party directly to the party
completing the repairs, or to the reimbursement of Debtor for the cost of such
repairs; provided, however, that Secured Party shall have no obligation to make
such payment or any part thereof until receipt of such evidence as Secured Party
shall deem satisfactory that such repairs have been completed and further
provided that Secured Party may apply such proceeds to the payment of any of the
Liabilities or the Other Liabilities due if at the time such proceeds are
received by Secured Party there shall have occurred and be continuing any Event
of Default hereunder or any event which with lapse of time or notice, or both,
would become an Event of Default. Debtor shall, when and as requested by Secured
Party, undertake, by litigation or otherwise, in Debtor's name, the collection
of any claim against


<PAGE>   3

any person for such destruction, damage, loss, theft, requisition or taking, but
Secured Party shall not be obligated to undertake, by litigation or otherwise,
the collection of any claim against any person for such destruction, damage,
loss, theft, requisition or taking.

     7. REPRESENTATIONS AND WARRANTIES OF DEBTOR. Debtor represents and warrants
that: it has the right, power and authority to enter into and carry out the
terms and provisions of this Agreement; this Agreement constitutes a valid
obligation of the Debtor and is enforceable in accordance with its terms; and
entering into this Agreement and carrying out its terms and provisions will not
violate the terms or constitute a breach of any other agreement to which Debtor
is a party.

     8. AFFIRMATIVE COVENANTS OF DEBTOR. Debtor shall (a) cause the Equipment to

cause to be made all needed and proper repairs, renewals and replacements
thereto; (b) maintain at all times property damage, fire, theft and
comprehensive insurance for the full replacement value of the Equipment, with

Secured Party as insureds with all of said insurance and loss payable provisions
to be in form, substance and amount and written by companies approved by Secured
Party, and deliver the policies therefor, or duplicates thereof, to Secured
Party; (c) pay or reimburse Secured Party for any and all taxes, assessments and
other governmental charges of whatever kind or character, however designated
(together with any penalties, fines or interest thereon) levied or based upon

operation, maintenance, repair, return or other disposition of the Equipment, or
upon any receipts or earnings arising therefrom, or for titling or registering
the Equipment, or upon the income or other proceeds received with respect to the
Equipment or this Agreement provided, however, that Debtor shall pay taxes on or

only to the extent that such net income taxes or franchise taxes are levied or
assessed in lieu of any other taxes, assessments or other governmental charges
hereinabove described; (d) pay all shipping and delivery charges and other
expenses incurred in connection with the Equipment and pay all lawful claims,
whether for labor, materials, supplies, rents or services, which might or could
if unpaid become a lien on the Equipment; (e) comply with all governmental laws,
regulations, requirements and rules, all instructions and warranty requirements
of Secured Party or the manufacturer of the Equipment, and with the conditions
and requirements of all policies of insurance with respect to the Equipment and
this Agreement; (f) mark and identify the Equipment with all information and in
such manner as Secured Party may request from time to time and replace promptly
any such marking or identification which are removed, defaced or destroyed; (g)
at any and all times during business hours, grant to Secured Party free access
to enter upon the premises wherein the Equipment shall be located and permit
Secured Party to inspect the Equipment; (h) reimburse Secured Party for all

and hold any assignee of Secured Party, and Secured Party, harmless from and

manufacture, purchase, ownership, delivery, possession, use, storage, operation,
maintenance, repair, return or other disposition of the Equipment or with this
Agreement, including, without limitation, claims for injury to or death of
persons and for damage to property, and give Secured Party prompt notice of any
such claim or liability; and (j) maintain a system of accounts established and
administered in accordance with generally accepted accounting principles and
practices consistently applied, and, within forty-five (45) days after the end

operations, performance or properties or a material impairment of the abilities
of Debtor to perform its obligations under its material agreements with its
primary customers, and as a result of such change in condition Secured Party
deems itself or any of the Equipment to be insecure;

then and in any such event, Secured Party may, at the sole discretion of Secured
Party, without notice or demand and without limitation of any rights and
remedies of Secured Party under the Uniform Commercial Code, take any one or
more of the following steps:

         (1) Declare all of the Time Balance to be due and payable, whereupon
the same shall forthwith mature and become due and payable as provided for in
paragraph 16 below, provided, however, upon the occurrence of any of the events
specified in subparagraphs (f) and (g) above, all sums as specified in this
clause (1) shall immediately be due and payable without notice to Debtor (the
date on which Secured Party declares all of the Time Balance to be due and
payable is hereinafter referred to as the "Declaration Date");

         (2) proceed to protect and enforce its rights by suit in equity, action
at law or other appropriate proceedings, whether for the specific performance of
any agreement contained herein, or for an injunction against a violation of any
of the terms hereof, or in aid of the exercise of any other right, power or
remedy granted hereby or by law, equity or otherwise; and

         (3) at any time and from time to time, with or without judicial process
and the aid or assistance of others, enter upon any premises wherein any of the
Equipment may be located and, without resistance or interference by Debtor, take
possession of the Equipment on any such premises, and require Debtor to assemble
and make available to Secured Party at the expense of Debtor any part or all of
the Equipment at any place or time designated by Secured Party; and remove any
part or all of the Equipment from any premises wherein the same may be located
for the purpose of effecting the sale or other disposition thereof; and sell,
resell, lease, assign and deliver, grant options for or otherwise dispose of any
or all of the Equipment


<PAGE>   6

in its then condition or following any commercially reasonable preparation or
processing, at public or private sale or proceedings, by one or more contracts,
in one or more parcels, at the same or different times, with or without having
the Equipment at the place of sale or other disposition, for cash and/or credit,
and upon any terms, at such place(s) and time(s) and to such persons, firms or
corporations as Secured Party shall deem best, all without demand for
performance or any notice or advertisement whatsoever, except that Debtor shall
be given five (5) business days' written notice of the place and time of any
public sale or of the time after which any private sale or other intended
disposition is to be made, which notice Debtor hereby agrees shall be deemed
reasonable notice thereof. If any of the Equipment is sold by Secured Party upon
credit or for future delivery, Secured Party shall not be liable for the failure
of the purchaser to pay for same and in such event Secured Party may resell such
Equipment. Secured Party may buy any part or all of the Equipment at any public
sale and if any part or all of the Equipment is of a type customarily sold in a
recognized market or which is the subject of widely distributed standard price
quotations Secured Party may buy at private sale and may make payment therefor
by application of all or a part of the Liabilities and of all or a part of any
Other Liabilities. Any personalty in or attached to the Equipment when
repossessed may be held by Secured Party without any liability arising with
respect thereto, and any and all claims in connection with such personalty shall
be deemed to have been waived unless notice of such claim is made by certified
or registered mail upon Secured Party within three business days after
repossession.

Secured Party shall apply the cash proceeds from any sale or other disposition
of the Equipment first, to the reasonable expenses of re-taking, holding,
preparing for sale, selling, leasing and the like, and to reasonable attorneys'
fees and other expenses which are to be paid or reimbursed to Secured Party
pursuant hereto, and second, to all outstanding portions of the Liabilities and
to any Other Liabilities in such order as Secured Party may elect, and third,
any surplus to Debtor, subject to any duty of Secured Party imposed by law to
the holder of any subordinate security interest in the Equipment known to
Secured Party; provided however, that Debtor shall remain liable with respect to
unpaid portions of the Liabilities owing by it and will pay Secured Party on
demand any deficiency remaining with interest as provided for in paragraph 16
below.

     12. SECURED PARTY'S RIGHT TO PERFORM FOR DEBTOR. If Debtor fails to perform
or comply with any of its agreements contained herein Secured Party may perform
or comply with such agreement and the amount of any payments and expenses
incurred by Secured Party in connection with such performance or compliance,
together with interest thereon at the rate provided for in paragraph 16 below,
shall be deemed a part of the Liabilities and shall be payable by Debtor upon
demand.

     13. FURTHER ASSURANCES. Debtor will cooperate with Secured Party for the
purpose of protecting the interests of Secured Party in the Equipment,
including, without limitation, the execution of all Uniform Commercial Code
financing statements requested by Secured Party. Secured Party and any assignee
of Secured Party are each authorized to the extent permitted by applicable law
to file one or more Uniform Commercial Code financing statements disclosing any
security interest in the Equipment without the signature of Debtor or signed by
Secured Party or any assignee of Secured Party as attorney-in-fact for Debtor.
Debtor will pay all costs of filing any financing, continuation or termination
statements with respect to this Agreement, including, without limitation, any
documentary stamp taxes relating thereto. Debtor will do whatever may be
reasonably necessary to have a statement of the interest of Secured Party and of
any assignee of Secured Party in the Equipment noted on any certificate of title
relating to the Equipment and will deposit said certificate with Secured Party
or such assignee. Debtor shall execute and deliver to Secured Party, upon
request, such other instruments and assurances as Secured Party deems reasonably
necessary or advisable for the implementation, effectuation, confirmation or
perfection of this Agreement and any rights of Secured Party hereunder.

     14. NON-WAIVER; ETC. No course of dealing by Secured Party or Debtor or any
delay or omission on the part of Secured Party in exercising any rights
hereunder shall operate as a waiver of any rights of Secured Party. No waiver or
consent shall be binding upon Secured Party unless it is in writing and signed
by Secured Party. A waiver on any one occasion shall not be construed as a bar
to or a waiver of any right and/or remedy on any future occasion. To the extent
permitted by applicable law, Debtor hereby waives the benefit and advantage of,
and covenants not to assert against Secured Party, any valuation, inquisition,
stay, appraisement, extension or redemption laws now existing or which may
hereafter exist which, but for this provision, might be applicable to any sale
or other disposition made under the judgment, order or decree of


<PAGE>   7

any court or under the powers of sale and other disposition conferred by this
Agreement or otherwise. Debtor hereby waives any right to a jury trial with
respect to any matter arising under or in connection with this Agreement.

     15. ENTIRE AGREEMENT; SEVERABILITY; ETC. This Agreement constitutes the
entire agreement between Secured Party and Debtor and all conversations,
agreements and representations relating to this Agreement or to the Equipment
are integrated herein. If any provision hereof or any remedy herein provided for
shall be invalid under any applicable law, such provision or remedy shall be
inapplicable and deemed omitted, but the remaining provisions and remedies
hereunder shall be given effect in accordance with the intent hereof. Neither
this Agreement nor any term hereof may be changed, discharged, terminated or
waived except in an instrument in writing signed by the party against which
enforcement of the change, discharge, termination or waiver is sought. This
Agreement shall in all respects be governed by and construed in accordance with
the internal laws of the State of New York, including all matters of
construction, validity and performance, and shall be deemed a purchase money
security agreement within the meaning of the Uniform Commercial Code. The
captions in this Agreement are for convenience of reference only and shall not
define or limit any of the terms or provisions hereof. This Agreement shall
inure to the benefit of and be binding upon Secured Party and Debtor and their
respective successors and assigns, subject, however, to the limitations set
forth in this Agreement with respect to Debtor's assignment hereof. No right or
remedy referred to in this Agreement is intended to be exclusive but each shall
be cumulative and in addition to any other right or remedy referred to in this
Agreement or otherwise available to Secured Party at law or in equity, and shall
be in addition to the provisions contained in any instrument referred to herein
and any instrument supplemental hereto. Debtor shall be liable for all costs and
expenses, including attorneys' fees and disbursements incurred by reason of the
occurrence of any Event of Default or the exercise of Secured Party's remedies
with respect thereto. Time is of the essence with respect to this Agreement and
all of its provision.

     16. PREPAYMENT; REBATE; INTEREST. Except for the installment payments of
the Time Balance as set forth in the Schedule of Obligations or as expressly
provided in the Prepayment Agreement of even date herewith, the Debtor may not
prepay the Time Balance, in whole or in part, at any time. In the event Secured
Party declares all of the Time Balance to be due and payable pursuant to clause
(1) of paragraph 11 above, Debtor shall pay to Secured Party an amount equal to
the sum of (a) all accrued and unpaid amounts as of the Declaration Date plus
interest thereon, and (b) the present value of all future installments set forth
in this Agreement over the remaining unexpired term of this Agreement discounted
to present value using a discount rate of four percent (4%), provided that the
amount of interest earned by Secured Party computed as aforesaid shall not
exceed the highest amount permitted by applicable law. The Time Balance as
reduced to present value in accordance with the preceding sentence shall bear
interest from and after the Declaration Date, and all other Liabilities due and
payable under this Agreement (including past due installments) shall bear
interest from and after their respective due dates, at the lesser of 1.5% per
month or the highest rate permitted by applicable law, provided, however, that
Debtor shall have no obligation to pay any interest on interest except to the

into a Data Center Services Agreement dated February 20, 1999, as the same may
have been modified prior to the date hereof (the "Customer Contract") relating
to the placement of certain equipment by Customer in Inflow's Data Network
Exchanges located at 1860 Lincoln Street, Suite 305, Denver, Colorado 80296 and
900 Bannock Street, Denver, Colorado 80204 (the "Facilities"). Customer has
advised InFlow that it has obtained financing from Wells Fargo Equipment
Finance, Inc. ("Lender") under a Loan Schedule to a Master Loan and Security
Agreement (the "Equipment Loan") of the equipment described in EXHIBIT A
attached to this letter (the "Equipment").

     InFlow acknowledges and agrees that the Equipment is financed by Lender,
and that, during the term of the Equipment Loan, InFlow shall not claim any
lien or other interest in the Equipment pursuant to the Customer Contract.
Pursuant to InFlow's lease of the Facilities, InFlow's landlords have
acknowledged that in no event will they have a lien on the property of any of
InFlow's customers. Upon written notice from Lender that Customer has defaulted
under the Equipment Loan, InFlow shall permit Lender to enter the Facilities in
the exercise of its rights and remedies arising under the Equipment Loan upon
the following terms and conditions: (1) Lender shall provide InFlow with
reasonable notice of its intent to enter the Facilities; (2) Lender shall enter
the Facilities only during reasonable business hours; (3) Lender shall comply
with all reasonable requirements and security procedures of InFlow related to
such entry; (4) Lender shall comply with all rules and regulations and other
requirements of InFlow's landlords for the Facilities; and (5) Lender shall
exercise its rights and remedies in such a manner as to cause the least
interference possible with other customers of InFlow and with the operations of
the Facilities. Customer hereby agree to indemnify, defend and hold InFlow and
its officers, directors, employees, agents, customers, vendors, successors and
assigns harmless from any and all liability, costs, expenses and damages,
including, without limitation, reasonable attorneys' fees and court costs
arising from or related to any entry into the Facilities or removal of the
Equipment or any other exercise of rights under the Equipment Loan by Lender.
Lender and Customer acknowledge and agree that InFlow shall be entitled to rely
upon any such notice from Lender,

                              PREPAYMENT AGREEMENT


         WHEREAS, Wells Fargo Equipment Finance, Inc. ("WFEFI"), as Secured
Party & MESSAGEMEDIA, INC. ("Debtor") are parties to certain Master Loan and
Security Agreement No. 10220 (the "Agreement"), dated December 22, 2000
affecting the equipment (the "Equipment") described therein; and

         WHEREAS, the parties hereto desire to confirm their understanding
pursuant to which the Debtor may prepay the Agreement on certain dates
("Prepayment Dates") set forth below.

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Provided that the Debtor shall so request WFEFI in writing not less
than thirty (30) days prior to a Prepayment Date, and further provided that the
Debtor shall have paid all monthly installments due through and including the
applicable Prepayment Date in accordance with the terms and provisions of the
Agreement and shall then be in compliance with all the terms and provisions of
the Agreement and shall continue to comply with all the terms and provisions of
the Agreement thereafter until such Prepayment Date, WFEFI agrees to allow
Debtor to prepay the Agreement (in whole, but not in part) by payment of the
appropriate prepayment amount as set forth below ("Prepayment Amount") in good
funds prior to the applicable Prepayment Date. A Prepayment Date shall mean one
day after the date that a regular monthly installment payment is due under the
Agreement, provided that there shall be no Prepayment Date prior to the date
that the twelfth payment has been paid.

         2. The Prepayment Amount which Debtor shall pay in the event of a
prepayment of the Agreement hereunder shall be computed as follows:

         (a) For a Prepayment Date which is after the day that the thirteenth
(13th) monthly installment is due but prior to the date that the twenty-fifth
(25th) payment is due, the Prepayment Amount shall be 104% of the remaining
principal balance due under the Agreement computed in accordance with the books
and records of Secured Party or its assigns;

         (b) For a Prepayment Date which is after the day that the twenty-fifth
(25th) monthly installment is due but prior to the date that the thirty-sixth
(36th) payment is due, the Prepayment Amount shall be 102% of the remaining
principal balance due under the Agreement computed in accordance with the books
and records of Secured Party or its assigns;

         3. All taxes attributable to the transaction herein contemplated
including any taxes on the Prepayment Amount, shall be borne exclusively by the
Lessee.

         4. Time is of the essence for the Lessee's making written request for
prepayment and for remitting the Prepayment Amount in the event Lessee timely
exercises its option to prepay hereunder.

         5. Except at specifically permitted by this Prepayment Agreement,
Lessee shall have no right to prepay the Agreement.

         6. This Prepayment Agreement shall constitute an indivisible part of
the Agreement and shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns.

              RIDER TO MASTER LOAN AND SECURITY AGREEMENT NO. 10220
                DATED DECEMBER 22, 2000 (THE "AGREEMENT") BETWEEN
  WELLS FARGO EQUIPMENT FINANCE, INC. AS SECURED PARTY ("SECURED PARTY") AND
                   MESSAGEMEDIA, INC. AS DEBTOR (THE "DEBTOR")

          Debtor and Secured Party covenant and agree as follows:

1. It shall be an Event of Default under the Agreement if Debtor shall fail to
be in compliance with any of the following during the term of any Loan
Schedule(s) to the Agreement (which together with the covenants contained in
Sections 3, 4 and 5 (if applicable) hereinbelow are hereafter referred to as the
"Financial Covenants"):

         (a)      Debtor's Unrestricted Cash shall be no less than (i)
                  $3,000,000.00 at all times from the date hereof through and
                  including March 31, 2001; and (ii) $2,000,000.00 at all times
                  from April 1, 2001 through the balance of the term of all Loan
                  Schedule(s) to the Agreement.

As used herein;

         Unrestricted Cash means the minimum cash balance on Debtor's balance
         sheet in the form of cash or readily marketable securities which has
         not been pledged, encumbered, restricted or otherwise assigned to or by
         any third party.

2. Provided that no Event of Default has occurred under the Agreement, and
Debtor has achieved, in all material respects, no less than ninety percent (90%)
of the projections contained on Exhibit 1 annexed hereto and made a part hereof
(the "Projections") through its fiscal year ending December 31, 2001 as
confirmed by Debtor's audited financial statements for such fiscal period; then,
upon Debtor's written request, Secured Party will consent to amend the Agreement
to delete therefrom the Financial Covenants contained in Section 1 (a)
hereinabove and to substitute in their place the following financial covenants,
which, in such event, shall, together with the covenants contained in Sections
3, 4 and 5 (if applicable) hereinbelow, thereafter be deemed to be the
"Financial Covenants" for the remaining term of all Loan Schedule(s) under the
Agreement:

(i) It shall be an Event of Default under the Agreement if Debtor shall fail to
be in compliance with any of the following during the term of any Loan
Schedule(s) to the Agreement:

         (a)      Debtor's Cash Flow Coverage Ratio shall be in an amount equal
                  to or greater than 1:1;

         (b)      Debtor's Tangible Net Worth shall be no less than
                  $15,000,000.00; and

         (c)      Debtor's Debt to Tangible Net Worth ratio shall be 1.5:1 or
                  less.

As used herein:

         Cash Flow Coverage Ratio shall mean the ratio of (x) the sum of net
         income, depreciation expense, amortization expense, less non-financed
         capital expenses, less distributions to shareholders, to (y) the sum of
         current maturities of obligations under capital leases and current
         maturities of loans, notes and other debts payable;

         Debt shall mean the sum of current and long-term maturities of
         obligations under capital leases, loans, notes and other debts payable
         as well as any demand notes relating to a revolving credit facility;

         Intangible Assets means the sum of all goodwill, value derived from all
         non-compete agreements, deferred income taxes and all other intangible
         assets, including but not limited to advances made



<PAGE>   14
         to affiliates, officers and employees; and

         Tangible Net Worth means (a) the sum of shareholders' equity plus
         subordinated debt, less (y), Intangible Assets.

3. Debtor shall raise additional equity in the amount of no less than
$8,000,000.00 by March 28, 2001 and shall deliver to Secured Party within
thirteen (13) days of such date, evidence in form and substance which is
satisfactory to Secured Party in its discretion, that Debtor has raised or
generated sufficient equity to comply with this covenant. After the funding of
Loan Schedule No. 1 to the Agreement, in the event that Secured Party supplies
additional financing to Debtor in the amount of $3,000,000.00 or more in Secured
Party's sole discretion on or by March 28, 2001, then the amount of additional
equity that Debtor shall be required to raise by such date under this Section 3
shall be changed to an amount of no less than $5,000,000.00.

4. Debtor shall grant, pledge and assign to Secured Party a first priority
security interest in all of Debtor's accounts receivable and notes receivable
which have been or are hereafter converted from accounts receivable to notes
receivable (collectively, the "Accounts") by executing such documentation as is
requested by Secured Party; such security interest shall not at any time exceed
the sum of the Liabilities and the Other Liabilities under the Agreement,
including all Loan Schedules thereto. Debtor shall establish a lockbox account
(the "Lockbox") pursuant to a lockbox agreement with Debtor's bank which is
acceptable in form and substance to counsel for Secured Party (the "Lockbox
Agreement"). Until such time as an Event of Default occurs under the Agreement,
Debtor shall have control of the proceeds of the Accounts contained in the
Lockbox. In the event that an Event of Default occurs under the Agreement,
Secured Party shall have the right to deliver the Instructions (as defined in
the Lockbox Agreement) to Debtor's bank to direct the proceeds of the Accounts
contained in the Lockbox to be remitted directly to Secured Party.

5. Provided that Debtor has complied with all of the following conditions: (a)
no Event of Default has occurred under the Agreement; (b) Debtor has had two (2)
consecutive fiscal quarters during which it has achieved, in all material
respects, no less than ninety percent (90%) of its projected net income
contained in its Projections, as confirmed by Debtor's financial statements for
such fiscal periods; and (c) Debtor has a working capital facility (the "Working
Capital Facility") in place with a financial institution which is acceptable to
Secured Party (the "Working Capital Lender"), then upon Debtor's request,
Secured Party will consent to: (i) subordinate Secured Party's security interest
in the Accounts to the security interest of the Working Capital Lender by
executing such documentation which is acceptable to counsel for Secured Party;
and (ii) amend Section 1 of this Rider to the Agreement to add the following
financial covenant which shall thereafter be deemed to be one of the "Financial
Covenants" under the Agreement:

         (d)      Debtor shall maintain Liquidity at all times which is equal to
                  or greater than the sum of all of the Liabilities and the
                  Other Liabilities under the Agreement, including all Loan
                  Schedules thereto. "Liquidity" shall mean the sum of
                  Unrestricted Cash and balance of available funds under the
                  Working Capital Facility.

6. Debtor's compliance with the Financial Covenants shall be measured on a
monthly basis. In order to enable Secured Party to review Debtor's compliance
with the Financial Covenants and the other terms, conditions and covenants of
the Agreement, Debtor shall within fifteen (15) days after the end of each
month, provide Secured Party with (a) an affidavit from the chief financial
officer for Debtor in the form annexed hereto as Exhibit 2 stating that Debtor
has complied and is then in compliance with each of the covenants contained in
this Rider, including without limitation, the Financial Covenants, or in the
event of any non-compliance, stating the extent of any such non-compliance; (b)
a balance sheet which accurately represents Debtor's financial condition as of
the end of such month; (c) a borrowing certificate showing the balance of
available funds as of the end of such month under the Working Capital Facility
(if any); and (d) a monthly accounting of the aging of the Accounts.



<PAGE>   15

7. It shall be an Event of Default if Debtor fails to be in compliance with any
of the provisions set forth hereinabove, including without limitation, the
Financial Covenants. In such event, Debtor shall deliver to Secured Party,
within fifteen (15) days of the occurrence of such failure, an irrevocable
standby letter of credit issued by a recognized financial institution acceptable
to Secured Party in an amount equal to the sum of the present value of the then
remaining payments due under all then existing Loan Schedules during the
remaining terms thereof, discounted at a rate equal to six percent (6%), which
letter of credit shall be substantially in the form annexed hereto as Exhibit 3
(the "LC"). Such LC shall secure the payment of all Liabilities (as defined in
the Agreement) and performance of all other obligations of Debtor to Secured
Party and its assigns under the Agreement. Once an LC is required under this
Section 7, it shall be an Event of Default under the Agreement if at any time
during which any amounts remain due under the Agreement or any Loan Schedule,
the LC is not in full force and effect or if Secured Party receives notice that
the LC will not be replaced or renewed. It is hereby further agreed that
provided that no other Event of Default (as defined in the above referred to
Agreement) shall have occurred on or before the end of each fiscal quarter
(each, a "Reduction Date"), the LC may be amended as provided below following
each Reduction Date to reduce the total face amount of the LC, to an amount
equal to the sum of the present value of the then remaining payments due under
all then existing Loan Schedules during the remaining terms thereof, discounted
at a rate equal to six percent (6%). Provided that no other Event of Default has
occurred, upon the request of Debtor following a Reduction Date, WFEFI will then
confirm in writing to the issuing bank that it may amend the LC to reduce the
face amount thereof in accordance with this Rider.

8. Debtor acknowledges that it has agreed to comply with the Financial Covenants
in strict compliance with the terms hereof in order to induce Secured Party to
enter into the Agreement and that Secured Party would not enter into the
Agreement except in reliance upon Debtor's agreement to strictly comply with the
terms hereof. Time is of the essence with regard to Debtor's compliance with the
terms hereof.

9. All other terms and conditions of the Agreement shall remain in full force
and effect. In the event that there is any conflict between the terms and
conditions of this Rider and the terms and conditions of the Agreement, the
terms and conditions of this Rider shall govern. All accounting terms not
defined herein shall have the meanings ascribed to them according to generally
