     network;

f)   Provide Internet equipment and backbone infrastructure at the Network

     customers, per Epoch's normal IP policies and as defined in Attachment A,

k)   Provision and install equipment and obtain locations for POPs, which shall
     be established and configured based on the projections of Branded Provider

     for spending the capital and resources;

l)   Make available Internet University training, in both classroom and online
     formats, to Branded Provider for training Branded Provider's sales,
     marketing and project management personnel. Branded Provider shall pay

m)   Within thirty (30) days of execution of this Agreement the parties shall
     meet to develop an implementation plan for fulfilling this Agreement; which
     shall be amended from time to time as needed.

3.   Branded Provider Responsibilities
     ---------------------------------

In consideration for being appointed as a Branded Provider, Branded Provider
assumes the following responsibilities:

a)   Solicit customers (e.g. companies, organizations and/or individuals who
     shall utilize Internet services) and maintain a trained and capable sales
     and support organization to solicit customers and support Epoch to assure
     customer satisfaction;

b)   Allocate necessary funding and personnel to support the Branded Product
     development, integration, marketing, sales, and training which shall ensure
     the success of the commitments made by both parties hereto;

c)   Present to potential customers an Internet Service Application (forms may
     be changed or adapted for Branded Providers' specific needs with
     authorization from Epoch). Branded Provider shall work with and assist such
     customers in completing the form, as updated from time to time by Epoch.
     Further, Branded Provider shall ensure that its personnel are adequately
     trained to assist such customers. The Service Application shall constitute
     a directive from Branded Provider to Epoch to provide the customer with all
     Services set forth therein. Branded Provider shall then be billed by Epoch
     for the Services in accordance with the prices set forth on Attachment A.
     Receipt of the Service Application by Epoch shall constitute a binding
     contract between Epoch and Branded Provider. Branded Provider understands
     that Epoch may refuse service to any customer, which is: (i) an Internet
     service provider using BGP, (ii) utilizes the UDP layer (streaming), (iii)
     violates or plans to violate generally accepted net protocol, including
     Epoch's Acceptable Use Policy ("AUP"), as such AUP may be modified from
     time to time by Epoch in its sole discretion (the most recent statement of
     Epoch's AUP is located at http://www.eni.net/products services/aup.html)
     (e.g. "spamming"), or (iv) breaches any provision of Epoch's standard
     Internet Services Agreement (the subject matter and provisions of which
     Branded Provider shall incorporate into its own agreement);

                                      -3-
<PAGE>

d)   Set prices for products and services provided to its customers independent
     of any prices charged by Epoch to its customers;

e)   Provide Epoch with a monthly forecast (the "Request") that forecasts four
     (4) months out, attached as Attachment B, that specifies the sales forecast
     for each type of Branded Service for each Market in which Branded Provider
     shall be selling such services. Epoch may rely on the Request to build
     infrastructure to meet Branded Providers forecasted needs. The Request
     shall include, at a minimum, a schedule of projected volume of dial-up and
     dedicated access customers and other information reasonably necessary for
     Epoch to project usage and build POPs. Furthermore, Epoch reserves the
     right, in its sole discretion, to decline to build a new POP or add
     capacity to an existing POP where Request does not warrant the investment
     of capital and resources by Epoch. In the event that Branded Provider
     requests that Epoch open any new POP or add capacity to an existing POP to
     serve the Request, then Branded Provider and Epoch shall enter into the POP
     Expansion Agreement attached as Exhibit A hereto;

f)   Branded Provider shall agree to pay the monthly minimum Revenue Commitment
     dollar amount as set forth on Attachment A, according the revenue Ramp
     (defined as a percentage of the minimum Revenue Commitment due in a given
     month) set forth in Attachment A, if billing based on actual network and/or
     services usage shall be less than as set forth in Attachment A;

g)   Take no action inconsistent with this Agreement, and reasonably support
     Epoch's efforts in providing Internet service to the customers.

4.   Pricing & Commissions
     ---------------------

Epoch shall provide products and services to Branded Provider's customers and
charge Branded Provider prices as agreed in Attachment A; such pricing shall not
change during the term of this Agreement except with the express written consent
of both parties. Epoch shall bill Branded Provider on a monthly basis for
services provided to customers by Epoch; with such billing occurring in advance
of the services provided for standard recurring charges (e.g. access is paid in
advance of the month) and in arrears following provisioning of services for
usage based or consulting services. All invoices are payable within thirty (30)
days of receipt. Unpaid invoices are subject to Epoch's then-current late
payment charge and interest of one percent (1%) per month on any outstanding
balance, or the maximum permitted by law, plus all expenses of collection. The
initial price and commission schedule is attached hereto as Attachment A.
Furthermore, all definitions in this Agreement shall be subject to modification
by Epoch at any time, upon thirty (30) days notice to Branded Provider as needed
to conform with Epoch's AUP and to control abusers of Internet services, as well
as to comply with regulatory authorities or changes of law.

5.   Trademarks and Related Matters
     ------------------------------

Branded Provider shall clearly mark its packaging and collateral materials with
the " Epoch"

                                      -4-
<PAGE>

logo. Epoch shall provide and periodically update a list of marks
which the Branded Provider may use, pursuant to the terms of this Agreement (the
"Marks"). All rights, title and interest in and to such Marks shall remain in
Epoch and Branded Provider shall not at any time challenge Epoch's rights in and
to said Mark or Marks or seek to obtain or obtain any rights therein. Any
unauthorized use of the Marks by Branded Provider or any person employed by or
contracting with Branded Provider, or any use not in compliance with the rules
and procedures prescribed by Epoch relating to such use, shall constitute an
infringement of Epochs rights in and to the Marks and be a material breach of
this Agreement.

Branded Provider agrees that upon the expiration or termination of this
Agreement, Branded Provider shall:

a)   Not thereafter use any actual or similar Marks in any manner or for any
     purpose; and,

b)   Destroy all advertising and marketing materials, forms, and other materials
     containing any Mark or otherwise identifying or relating to Epoch.

6.   Confidentiality, Non-Disclosure, Trade Secrets & Intellectual Property
     ----------------------------------------------------------------------
Rights
------

a)   For purposes of this Agreement, the term "Confidential Information" shall
     mean all documents, information, financial statements, agreements, software
     programs, pricing information, contracts, know-how, inventories,
     projections, customer names, customer requirements, materials, details,
     programs, software, specifications, techniques, properties, methods,
     manufacturing processes, marketing and sales plans and techniques, employee
     lists and information regarding employees such as work habits, skills, and
     areas of expertise, products and services, as well as future and proposed
     products and services, and other data, or any combination thereof, whether
     or not the party who disclosed such Confidential Information ("Disclosing
     Party") is the owner of such Confidential Information, which is disclosed
     to the other party hereunder ("Receiving Party") by the Disclosing Party,
     whether or not such information is or is not generally known to the public
     or to other persons, and whether or not economic value may be obtained from
     its disclosure or use by others.

b)   The Receiving Party, along with its employees and agents, shall hold and
     maintain the Confidential Information in strictest confidence and in trust
     for the sole and exclusive benefit of the Disclosing Party.

c)   The Receiving Party shall not, without the prior written approval of the
     Disclosing Party, use for its own benefit, nor for the benefit of others,
     other than in connection with this Agreement, nor publish or otherwise
     disclose to others, or permit any use by others for their benefit or to the
     detriment of the Disclosing Party, any of the Confidential Information.

d)   The Receiving Party shall carefully restrict access to the Confidential
     Information received from the Disclosing Party to the officers, directors,
     employees, partners, and

                                      -5-
<PAGE>

     professional advisors of the Receiving Party, who clearly need such access.
     The Receiving Party further warrants and represents that it shall advise
     each of the persons to whom it provides access to any of the Confidential
     Information pursuant to this paragraph that such persons are strictly
     prohibited from making any use, publishing or otherwise disclosing to
     others, or permitting others to use for their benefit or to the detriment
     of the Disclosing Party, any of the Confidential Information except as
     required in the performance of its duties hereunder.

e)   The Receiving Party shall take all necessary action to protect the
     confidentiality of the Confidential Information, except for its disclosure
     pursuant to paragraph (d) above, and hereby agrees to be held accountable
     to the Disclosing Party for any and all losses, damages, claims, or
     expenses incurred or suffered by the Disclosing Party as a result of the
     Receiving Party's breach of this Agreement.

f)   The Receiving Party shall not solicit the employment of, or the termination
     of employment with the Disclosing Party, of any employee, officer, or
     director of the Disclosing Party.

g)   The Receiving Party understands and acknowledges that any disclosure or
     misappropriation of any of the Confidential Information or the solicitation
     or employment of any employees, officers or directors of the Disclosing
     Party is in violation of this Agreement and shall constitute a material
     breach of the Agreement as well as irreparable business harm, the amount of
     which may be difficult to ascertain and, therefore, agrees that the
     Disclosing Party shall have the right to apply to a court of competent
     jurisdiction for an order restraining any such violation and for such other
     relief as the Disclosing Party shall deem appropriate. The right of the
     Disclosing Party to enjoin a violation of this Agreement is to be in
     addition to the remedies otherwise available to the Disclosing Party at law
     or in equity.

h)   The Receiving Party shall return to the Disclosing Party any and all
     records, notes, and other written, printed, or tangible materials
     containing the Confidential Information immediately in the event of the
     termination of this Agreement; provided, however, that any failure by the
     Disclosing Party to request the return of such materials shall not affect
     the duties of the Receiving Party as provided for in this Agreement.

i)   Each party represents to the other party that it is the owner or licensee
     of all proprietary software and intellectual property provided by such
     party under the terms of this Agreement. To the extent that Branded
     Provider requests Epoch to develop new software which is deemed proprietary
     by and to Branded Provider then Branded Provider shall own all rights and
     interest to such software. Branded Provider shall not own any rights to
     software which is proprietary to Epoch, even though Branded Provider may
     have paid reasonable fees for Epoch to customize such Epoch software for
     Branded Provider's use while under this Agreement; specific examples of
     which include, but are not limited to, CustomDial, SmartList, and
     Start.page.

the sum of all minimum monthly Revenue Commitments, as set forth on Attachment
A, for each remaining month in the term of this Agreement; in addition to any
and all amounts currently due and owing.

Either party may terminate this Agreement "for cause" in the event that the
other party hereto breaches any material term of this Agreement. In the event
that such breach is made by Epoch, then Branded Provider may terminate the
Agreement without penalty. In the event that such breach is made by Branded
Provider, then Epoch may terminate the Agreement and require payment from
Branded Provider equal to the minimum monthly Revenue Commitment defined in
Attachment A for the remaining balance of the term of the Agreement. In either
case, any and all past due amounts outstanding shall be payable prior to any
termination. Prior to the effectiveness of such termination the party noticing

breach which clearly describes the problem(s) constituting cause; the other
party shall then have sixty (60) days to correct and cure the breach. Should the
breach be cured, then this Agreement shall remain in full force and effect.
