                                                                   No.   A
                                                                      ---------

       This Master Lease Agreement (the "MLA") is entered into by and between
Ascend Credit Corporation ("Lessor"), having its principal place of business at
1701 Harbor Bay Parkway, Alameda, CA 94502 and FASTNET Corporation (f/k/a YOU
TOOLS CORPORATION) ("Lessee"), having its principal place of business at Two
Courtney Place, #130, 3864 Courtney Street, Bethlehem, PA 18017.

1.     LEASE AGREEMENT.  Lessor agrees to lease to Lessee, and Lessee agrees
to lease from Lessor, the equipment (the "Equipment") referenced in each of
the Schedules (the "Schedule" or "Schedules") which incorporate this MLA
therein (the "Lease").  So long as no Event of Default has occurred or is
continuing, Lessor agrees to lease to Lessee the groups of Equipment
described on each Schedule, subject to the following conditions, which Lessor
in its sole discretion may elect to waive with respect to a Schedule:  (i)
that in no event shall Lessor be obligated to lease Equipment to Lessee
hereunder where the aggregate purchase of all Equipment leased to Lessee
hereunder would exceed [*]; (ii) the Equipment leased hereunder shall only be
Equipment manufactured by either Ascend Communications, Inc. or Lucent
Technologies or its affiliates; (iii) that [*] hereunder will be available to
the Lessee for Equipment leases upon execution; (iv) that the remaining [*]
hereunder will be available to the Lessee for Equipment leases upon Lessee
providing Lessor with verification that a minimum of [*] in new equity has
been received; (v) that the lease amount shall not include more than 10% for
freight, installation, maintenance, professional services and taxes and that
such amounts above the limit will be paid for by the Lessee; and (vi) no new
leases shall be issued after June 30, 2000.

2.     TERM.  Each Lease shall be effective upon the execution of the MLA and
the related Schedule by the Lessor and the Lessee.  The lease term (the "Lease
Term") of the Equipment referenced in each of the Schedules shall commence on
the rent commencement date specified in each Schedule (the "Rent Commencement
Date").  The Rent Commencement Date shall be the date 30 days from the date that
the Equipment is shipped by the supplier (the "Ship Date") as evidenced by a
shipping document provided by the supplier related to the Equipment (the
"Shipping Document").  Lessor will provide Lessee with a copy of the Shipping
Document evidencing the Ship Date.

3.     RENT.  The rent (the "Rent") for the Equipment referenced in any Schedule
shall be as stated in such Schedule and shall be payable according to the
provisions of such Schedule.  If any amount payable under a Schedule is not
received by Lessor within 10 days of the due date, Lessee agrees to pay an
Overdue Charge, as defined herein, with respect to such amount.

4.     SELECTION AND ASSIGNMENT.  Lessee will select the type, quantity and
Supplier

omitted. The confidential portion has been filed separately with the
Securities and Exchange Commission.

(subject to above) of each item of Equipment designated in a Schedule, and
Lessee hereby assigns to Lessor all of its right, title and interest in and to
the related equipment purchase agreement, a copy of which has been provided to
Lessor by Lessee (the "Agreement").  The Agreement may be amended with the
consent of Lessor.  Any such assignment with respect to Equipment shall become
binding upon Lessor when Lessor and Lessee have entered into a Lease with
respect to such Equipment and as of the Rent Commencement Date referenced in
such Lease.  Upon such an assignment becoming effective, Lessor shall be
obligated to purchase the Equipment from the Supplier in accordance with the
provisions of the Agreement.  It is expressly agreed that Lessee shall at all
times remain liable to Supplier under the Agreement to perform all duties and
obligations of Lessee thereunder, except for the obligation to purchase the
Equipment to the extent expressly assumed by the Lessor hereunder, and that the
Lessee shall be entitled to the same rights of the purchaser of the Equipment
under the Agreement, except such right, title and interest in the Equipment
retained exclusively by the Lessor as owner of the Equipment.  Lessor shall have
no liability for a Supplier's failure to meet the terms and conditions of the
Agreement.

5.     DELIVERY AND INSTALLATION.  Lessee shall be responsible for payment of
all transportation, packing, installation, testing and other charges associated
with the delivery, installation or use of any Equipment which are not included
in the Agreement with respect to such Equipment.

6.     WARRANTIES.  LESSOR MAKES NO REPRESENTATION OR WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, WITH RESPECT TO ANY OF THE EQUIPMENT, ITS MERCHANTABILITY,
OR ITS FITNESS FOR A PARTICULAR PURPOSE.  LESSOR SHALL NOT BE LIABLE TO LESSEE
OR ANY OTHER PERSON FOR DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES ARISING FROM LESSEE'S USE OF THE EQUIPMENT, OR FOR DAMAGES BASED ON
STRICT OR ABSOLUTE TORT LIABILITY OR LESSOR'S PASSIVE NEGLIGENCE.  LESSEE HEREBY
ACKNOWLEDGES THAT ANY MANUFACTURER'S OR SUPPLIER'S WARRANTIES WITH RESPECT TO
THE EQUIPMENT ARE FOR THE BENEFIT OF BOTH LESSOR AND LESSEE.  NOTWITHSTANDING
THE FOREGOING, LESSEE'S OBLIGATIONS TO PAY EACH RENT PAYMENT DUE, OR OTHERWISE
PERFORM ITS OBLIGATIONS, UNDER THIS LEASE ARE ABSOLUTE AND UNCONDITIONAL.

7.     TITLE TO AND LOCATION OF EQUIPMENT.  Lessor shall retain title to each
item of Equipment. Lessee, at its expense, shall protect Lessor's title and keep
the Equipment free from all claims, liens, encumbrances and legal processes.
The Equipment is personal property and is not to be regarded as part of the real
estate on which it may be situated.  If requested by Lessor, Lessee will, at
Lessee's expense, furnish a landlord or mortgagee waiver with respect to the
Equipment.  The Equipment shall not be removed from the location specified in
the Schedule without the written consent of Lessor.  Lessee shall, upon Lessor's
request, affix and maintain plates, tags or other identifying labels, showing
Lessor's ownership of the Equipment in a prominent position on the Equipment .

8.     USE OF EQUIPMENT, INSPECTION AND REPORTS.  The use of the Equipment by
Lessee shall conform with all applicable laws, insurance policies, and
warranties of the manufacturer or Supplier of the Equipment.  Lessor shall have
the right to inspect the Equipment

                                       2
<PAGE>

at the premises where the Equipment is located. Lessee shall notify Lessor
promptly of any claims, liens, encumbrances or legal processes with respect to
the Equipment.

9.     FURTHER ASSURANCES.  Lessee shall execute and deliver to lessor such
instruments as Lessor deems necessary for the confirmation of this Lease and
Lessor's rights hereunder.  Lessor is authorized to file financing statements
signed only by the Lessor in accordance with the Uniform Commercial Code, or
financing statements signed by Lessor as Lessee's attorney-in-fact.  Any such
filing with respect to the Equipment leased pursuant to a true lease shall not
be deemed evidence of any intent to create a security interest under the Uniform
Commercial Code.

10.    MAINTENANCE AND REPAIRS.  Lessee shall, at its expense, maintain each
item of Equipment in good condition, normal wear and tear excepted.  Lessee
shall not make any addition, alteration, or attachment to the Equipment without
Lessor's prior written consent.  Lessee shall make no repair, addition,
alteration or attachment to the Equipment which interferes with the normal
operation or maintenance thereof,  creates a safety hazard, or might result in
the creation of a mechanic's or materialman's lien.

11.    LESSOR'S PERFORMANCE OF LESSEE'S OBLIGATIONS.  If Lessee fails to perform
any of its obligations under a Lease, Lessor may perform any act or make any
payment which Lessor deems necessary for the maintenance and preservation of the
Equipment subject thereto and Lessor's title thereto.  All sums so paid by
Lessor (together with all related Overdue Charges), and reasonable attorneys'
fees incurred by Lessor in connection therewith, shall be additional rent
payable to Lessor on demand.  The performance of any such act or the making of
any such payment by Lessor shall not be deemed a waiver or release of any
obligation or default on the part of Lessee.

12.    INDEMNIFICATION.  Lessee assumes liability for, and hereby agrees to
indemnify, protect and hold harmless, Lessor, and its agents, employees,
officers, directors, partners and successors and assigns, from and against, all
liabilities, obligations, losses, damages, injuries, claims, demands, penalties,
actions, costs and expenses, including, without limitation, reasonable
attorneys' fees, of whatever kind and nature, in contract or in tort, arising
out of the use, condition, operation, ownership, selection, delivery, leasing or
return of any item of Equipment, regardless of when, how and by whom operated,
or any failure on the part of Lessee to perform or comply with any of its
obligations under a Lease, excluding, however, any of the foregoing which result
from the gross negligence or willful misconduct of Lessor.  Such indemnities and
assumptions of liabilities and obligations shall continue in full force and
effect, notwithstanding the expiration or other termination of such Lease.
Nothing contained in any Lease shall authorize Lessee to operate the Equipment
subject thereto so as to incur or impose any liability on, or obligation for or
on behalf of, Lessor.

13.    NO OFF-SET. All Rents shall be paid by Lessee irrespective of any
off-set, counterclaim, recoupment, defense or other right which Lessee may have
against Lessor, the manufacturer or Supplier of the Equipment or any other
party.

14.    ASSIGNMENT BY LESSEE.  Lessee shall not, without Lessor's prior written
consent, (a) sell, assign, transfer, pledge, hypothecate, or otherwise dispose
of, encumber or suffer to exist a lien upon or against, any of the Equipment or
any Lease or any interest therein, by operation of

                                       3
<PAGE>

law or otherwise, or (b) sublease or lend any of the Equipment or permit any of
the Equipment to be used by anyone other than Lessee.

15.    ASSIGNMENT BY LESSOR.  Lessor may assign, sell or encumber its interest
in any of the Equipment and any Lease.  Upon Lessor's written consent, Lessee
shall pay directly to the assignee of any such interest all Rent and other sums
due under an assigned Lease.  THE RIGHTS OF ANY SUCH ASSIGNEE SHALL NOT BE
SUBJECT TO ANY ABATEMENT, DEDUCTION, OFF-SET, COUNTERCLAIM, RECOUPMENT, DEFENSE
OR OTHER RIGHT WHICH LESSEE MAY HAVE AGAINST LESSOR OR ANY OTHER PERSON OR
ENTITY.  Notwithstanding the foregoing, any such assignment (a) shall be subject
to Lessee's right to possess and use the Equipment subject to a Lease so long as
Lessee is not in default thereunder, and (b) shall not release any of Lessor's
obligations hereunder.

16.    RETURN OF EQUIPMENT.  Unless Lessee has exercised its option, if any, to
renew a lease or purchase the Equipment subject thereto, upon expiration of the
then current Lease Term of such Lease, Lessee shall, at its expense, cause such
Equipment to be removed, disassembled, and placed in the same condition as when
delivered to Lessee (reasonable wear and tear excepted) and properly crate such
Equipment for shipment and deliver it to a common carrier designated by Lessor.
Lessee will ship such Equipment, F.O.B. destination, to any address specified in
writing by Lessor within the continental United States.  All additions,
attachments, alterations and repairs made or placed upon any of the Equipment
shall become part of such Equipment and shall be the property of Lessor.

17.    EVENTS OF DEFAULT.  The occurrence of any of the following shall be
deemed to constitute an Event of Default hereunder:  (a) Lessee fails to pay
Rent, any other amount it is obligated to pay under a Lease or any other amount
it is obligated to pay to Lessor and does not cure such failure within 10 days
of such amount becoming due; (b) Lessee fails to perform or observe any
obligation or covenant to be performed or observed by Lessee hereunder or under
any Schedule, including, without limitation, supplying all requested
documentation, and does not cure such failure within 10 days of receiving
written notice thereof from Lessor; (c) the occurrence  and continuance of any
default under any other lease or agreement for borrowed money made between
Ascend Communications, Inc. or its affiliates or successors, and the Lessee; (d)
any warranty, representation or statement made or furnished to Lessor by or on
behalf of Lessee is proven to have been false in any material respect when made
or furnished; (e) the attempted sale or encumbrance by Lessee of the Equipment,
or the making of any levy, seizure or attachment thereof or thereon; or (f) the
dissolution, termination of existence, discontinuance of business, insolvency,
or appointment of a receiver of any part of the property of Lessee, assignment
by Lessee for the benefit or creditors, the commencement of proceedings under
any bankruptcy, reorganization or arrangement laws by or against Lessee, or any
other act of bankruptcy on the part of Lessee.

18.    REMEDIES OF LESSOR.  At any time after the occurrence of any Event of
Default, Lessor may exercise one or more of the following remedies: (a) Lessor
may terminate any or all of the Leases with respect to any or all items of
Equipment subject thereto; (b) Lessor may recover from Lessee all Rent and other
amounts then due and to become due under any or all of the Leases; (c) Lessor
may take possession of any or all items of Equipment, wherever the same may be
located, without demand or notice, without any court order or other process of
law and

                                       4
<PAGE>

without liability to Lessee for any damages occasioned by such taking of
possession, and any such taking of possession shall not constitute a termination
of any Lease; (d) Lessor may demand that Lessee return any or all items or
Equipment to Lessor in accordance with Paragraph 16; and (e) Lessor may pursue
any other remedy available at law or in equity, including, without limitation,
seeking damages, specific performance or an injunction.

       Upon repossession or return of any item of the Equipment, Lessor shall
sell, lease or otherwise dispose of such item in a commercially reasonable
manner, with or without notice and on public or private bid, and apply the net
proceeds thereof (after deducting the estimated fair market value of such item
at the expiration of the term of the applicable Lease, in the case of a sale, or
the rents due for any period beyond the scheduled expiration of such Lease, in
the case of any subsequent lease of such item, and all expenses, including,
without limitation, reasonable attorneys' fees, incurred in connection
therewith) towards the Rent and other amounts due under such Lease, with any
excess net proceeds to be retained by Lessor.

       Each of the remedies under this Lease shall be cumulative, and not
exclusive, and in addition to any other remedy referred to herein or otherwise
available to Lessor in law or in equity.  Any repossession or subsequent sale or
lease by Lessor of any item of Equipment shall not bar an action for a
deficiency as herein provided, and the bringing of an action or the entry of
judgment against Lessee shall not bar Lessor's right to repossess any or all
items of Equipment.

19.    CREDIT AND FINANCIAL INFORMATION.  Within 90 days of the close of each of
Lessee's fiscal years, Lessee shall deliver to Lessor a copy of Lessee's annual
report, if any, and an audited balance sheet and profit and loss statement with
respect to such year.  Within 30 days after the end of each of Lessee's fiscal
months, Lessee shall deliver to Lessor a balance sheet and profit and loss
statement for such month and, if requested, any other additional information
regarding historical or projected operating performance reasonably requested by
Lessor, all of which shall be certified by an officer of Lessee.  Upon Lessee
becoming a publicly traded company, fiscal year and reporting requirements will
change to 120 days and the monthly reporting requirements will change to fiscal
quarters and be due 60 days after each quarter.

20.    INSURANCE.  As of the date that risk of loss for the Equipment passes
from the Supplier to the Lessee under the terms of the Agreement, Lessee shall
obtain and maintain through the end of the Lease Term of each Lease (and any
renewal or extension thereof), at its own expense, property damage and personal
liability insurance and insurance against loss or damage to the Equipment,
including, without limitation, loss by fire (with extended coverage), theft and
such other risks of loss as are customarily insured against with respect to the
types of Equipment leased hereunder and by the types of businesses in which such
Equipment will be used by Lessee.  Such insurance shall be in such amounts, with
such deductibles, in such form and with such insurers as shall be satisfactory
to Lessor; provided, however, that the amount of the Insurance against loss or
damage to the Equipment shall not be less than the greater of the replacement
value of the Equipment, from time to time, or the original purchase price of the
Equipment.  Each insurance policy shall name Lessee as an insured and Lessor as
an additional insured or loss payee, and shall contain a clause requiring the
insurer to give Lessor at least 30 days prior written notice of any alteration
in the terms of such policy or of the cancellation thereof.  Lessee shall
furnish to Lessor a certificate of insurance or other evidence satisfactory to
Lessor that such insurance coverage is in effect; provided, however, that Lessor
shall be under no

                                       5
<PAGE>

duty either to ascertain the existence of or to examine such insurance policy or
to advise Lessee in the event such insurance coverage shall not comply with the
requirements hereof. Lessee shall give Lessor prompt notice of any damage to, or
loss of, any of the Equipment, or any part thereof, or any personal injury or
property damage occasioned by the use of any of the Equipment.

21.    TAXES.  Lessee hereby assumes liability for, and shall pay when due, and,
on a net after-tax basis, shall indemnify, protect and hold harmless Lessor
against all fees, taxes and governmental charges (including, without limitation,
interest and penalties) of any nature imposed on or in any way relating to
Lessor, Lessee,  any item of Equipment or any Lease, except state and local
taxes on or measured by Lessor's net income (other than any such tax which is in
substitution for or relieves Lessee from the payment of taxes it would otherwise
be obligated to pay or reimburse to Lessor as herein provided) and federal taxes
on Lessor's net income.  Lessee shall, at its expense, file when due with the
appropriate authorities any and all tax and similar returns, and reports
required to be filed with respect thereto, for which it has indemnified Lessor
hereunder or, if requested by Lessor, notify Lessor of all such requirements and
furnish Lessor with all information required for Lessor to effect such filings.
Any fees, taxes or other charges paid by Lessor upon failure of Lessee to make
such payments shall, at Lessor's option, become immediately due from Lessee to
Lessor and shall be subject to the Overdue Charge from the date paid by Lessor
until the date reimbursed by Lessee.

22.    SEVERABILITY.  If any provision of any Lease is held to be invalid by a
court of competent jurisdiction, such invalidity shall not affect the other
provisions of such Lease or any provision of any other Lease.

23.    NOTICES.  All notices hereunder shall be in writing and shall be deemed
given when sent by certified mail, postage prepaid, return receipt requested,
addressed to the party to which it is being sent at its address set forth herein
or to such other address as such party may designate in writing to the other
party.

24.    AMENDMENTS, WAIVERS AND EXTENSIONS. This MLA and each Schedule
constitute the entire agreement between Lessor and Lessee with respect to the
Lease of the Equipment subject to such Schedule, and supersede all previous
communications, understandings, and agreements, whether oral or written, between
the parties with respect to such subject matter. No provision of any Lease may
be changed, waived, amended or terminated except by a written agreement,
specifying such charge, waiver, amendment or termination, signed by both Lessee
and Lessor, except that Lessor may insert, on the appropriate schedule, the
serial number of Equipment, after delivery of such Equipment, and the Rent
Commencement Date for the Equipment. No waiver by Lessor of any Event of Default
shall be construed as a waiver of any future Event of Default or any other Event
of Default. At the expiration of the Lease Term with respect to a Lease, upon
notice given by Lessee at least ninety (90) days prior thereto, (a) such Lease
shall be renewed or the Equipment subject thereto shall be purchased under the
terms and conditions set forth herein for a term and rent amount or purchase
price, as the case may be, to be agreed upon, or (b) if no such agreement is
reached prior to the expiration of such Lease Term or such notice specifies that
Lessee intends to return the Equipment, then Lessee shall return the Equipment
to Lessor in the manner prescribed in Paragraph 16 of this MLA. In the absence
of Lessor's timely receipt of the notice contemplated by the preceding

                                       6
<PAGE>

sentence, the Lease shall be automatically extended, on a month-to-month basis,
until terminated (upon notice by either party given at least ninety (90) days
prior to the end of the month on which the termination is to be effective) or
until renewed or the Equipment subject thereto is purchased by agreement of the
parties. Unless otherwise agreed, Lessee shall continue to pay rent for each
month following such Lease Term until the Equipment subject to such Lease is
returned pursuant to Paragraph 16 of this MLA.

25.    CONSTRUCTION.  This MLA shall be governed by and construed in accordance
with the internal laws, but not the choice of laws provisions, of the State of
California.  The titles of the sections of this MLA are for convenience only and
shall not define or limit any of the terms or provisions hereof.  Time is of the
essence in each of the provisions hereof.

26.    PARTIES.  This MLA shall be binding upon, and inure to the benefit of,
the permitted assigns, representatives and successors of the Lessor and Lessee.
If there is more than one Lessee named in this MLA, the liability of each shall
be joint and several.

27.    COUNTERPARTS.  Each Lease may be executed in two or more counterparts,
each of which shall be deemed an original and all of which together shall
constitute but one and the same instrument.

28.    OVERDUE CHARGE.  Overdue Charge shall mean an amount equal to 2% per
month of any payment under a Lease which is past due, including, without
limitation, any amounts not included in any payment of Rent hereunder, or the
highest charge permitted by law, whichever is lower.

The person executing this MLA on behalf of Lessee hereby certifies that he or
she has read, and is duly authorized to execute, this MLA.

Both sides recognize that this term sheet is not the definitive agreement.  The
terms of this proposal will be set forth in the lease agreement, both parties

                    FASTNET-WebTV Network Services Agreement

     This Agreement is made and entered into on this September 4, 1997

                    dedicated physical or virtual circuit) connection, at WNI's
                    election as further described in Schedule C. Except as
                    otherwise provided in Schedule C, the cost for establishing
                    and maintaining such connectivity shall be included with the
                    prices stated in schedule B.

          1.2  NETWORK PERFORMANCE: FASTNET shall use all commercially
               reasonable efforts to operate its network services seven (7) days
               per week, twenty-four (24) hours per day, each day of the year.
               FASTNET's telecommunications services provided to WNI should be,
               at a minimum, of a quality usual and customary in the industry
               for regional Internet access providers.

          1.3  NETWORK INTEROPERABILITY: Both parties agree to comply with the
               technical requirements listed in Schedule A.

          1.4  NETWORK COVERAGE: FASTNET currently maintains a local calling
               area footprint of local access numbers (each, a "dialup POP") in
               Delaware, New Jersey, and Pennsylvania, as described in Schedule
               D. FASTNET will not reduce this local calling area coverage below
               90% of the existing local calling areas listed in Schedule D, for
               a period greater than thirty (30) days. FASTNET shall provide WNI
               with thirty (30) days written

<PAGE>

               notice prior to discontinuing an existing local access number
               and/or a particular geographic location. If FASTNET breaches any
               obligation of this Section 1.4, WNI shall have the right to
               renegotiate all terms and conditions of this Agreement without
               affecting the validity and enforceability of this Agreement until
               this Agreement is replaced by a new agreement between the parties
               or until this Agreement is otherwise terminated as provided
               herein. If such renegotiation does not result in an agreement
               between the parties within thirty (30) days, WNI shall have the
               right to immediately terminate this Agreement.

          1.5  CUSTOMER SERVICE: WNI is responsible for all Subscriber customer
               support, billing, and collections. FASTNET shall not be
               responsible for any hardware or software requirements of WNI's
               Subscribers to connect with FASTNET's facilities. FASTNET's
               relationship under this agreement is solely with WNI and not with
               any WNI Subscriber.

          1.6  TECHNICAL SUPPORT: FASTNET shall provide to WNI a network
               operations Internet email address for reporting by WNI to FASTNET
               of problems in FASTNET's connectivity or performance affecting
               WNI subscribers and transmittal of trouble tickets initiated from
               WNI's Service Operations Center. FASTNET shall monitor said
               mailbox to insure acknowledgment of email problem reports and/or
               trouble tickets within one (1) hour of receipt and shall insure
               that problem resolution for trouble tickets received is reported
               back to the designated WNI Service Operations Center email
               address within one hour of resolution. FASTNET will provide email
               notification to a designated WNI Internet email address of any
               service problems which may affect WNI subscribers within one (1)
               hour of discovery, including but not limited to POP failures,
               Internet access interruptions or routing instabilities, telco
               connectivity problems, dial-in port outages or serious congestion
               (latency) problems.

               In addition, FASTNET shall provide WNI with a toll-free number
               and a pager number to report problems relating to FASTNET's
               network availability or performance which affect WNI subscribers
               and to escalate problems which are significantly affecting WNI
               subscribers, whether or not previously reported by email. The
               toll-free and pager numbers shall be used only by WNI and shall
               not be released to WNI's Subscribers. Such telephone assistance
               shall be available to WNI on a continuous basis, twenty-four (24)
               hours per day, seven (7) days per week, for each day of the year,
               and shall be provided by a qualified technician. FASTNET shall
               use commercially reasonable efforts to begin analysis of any
               request for assistance or report of problems as soon as possible
               after discovery thereof, and in no event more than one half hour
               after any call made by WNI for such purpose. FASTNET shall make
               all repairs required for the proper functioning of its systems as
               soon as commercially reasonable after the discovery thereof or
               WNI's notice to FASTNET thereof. FASTNET

<PAGE>

               shall actively monitor the performance of its systems, and shall
               notify WNI promptly of any condition which materially adversely
               affects such performance. FASTNET will provide WNI with notice as
               far in advance as is reasonably possible as to the changes in its
               service infrastructure, hours of operation, modification to
               communications protocols and any other planned changes in the
               service that could reasonably be expected to have a material
               affect on WNI's ability to service its end users.

          1.7  RESALE: The services provided by FASTNET are for the use of WNI
               Subscribers, and WNI will not resell the services provided by
               FASTNET hereunder to any other party for resale by such party
               except with the prior written approval of FASTNET, which approval
               shall be in the sole discretion of FASTNET, and only if such
               party agrees in writing to all of the terms and conditions of
               this Agreement. WNI shall not at any time or in any manner
               represent itself as the operator of FASTNET.

          1.8  PROJECT MANAGEMENT: Prior to the termination of the testing
               period provided in Section 7, each party will assign a project
               manager for the term of the contract to serve as the other
               party's primary single point of contact.

          1.9  REPORTING: Within five (5) business days of the end of each
               calendar month, and in no event later than the date that any
               invoice pursuant to Section 2.2 is delivered, FASTNET shall
               provide WNI with monthly usage data detailing network access by
               WNI's Subscribers, on which FASTNET shall base its billing to
               WNI.

2.        PRICING AND BILLING

          2.1  PRICING: The prices in Schedule B apply for all services provided
               by FASTNET under this Agreement. For all other services which WNI
               may request, FASTNET's list prices apply unless other prices have
               been specifically negotiated.

          2.2  INVOICES: FASTNET shall provide to WNI a monthly invoice for all
               sums due pursuant to this Agreement, and WNI agrees to pay all
               such invoices to FASTNET no later than thirty (30) days after the
               receipt of such invoices. Any disputed amounts shall be resolved
               by arbitration pursuant to the provisions of Section 13. Any
               payment made more than thirty (30) days after due is subject to a
               charge of the lesser of 1% per month or the maximum legal
               interest rate.

          2.3  NETWORK AVAILABILITY: In the event that certain percentages of
               Customers cannot establish a connection at FASTNET's POPs, the
               following shall apply:

<PAGE>

                    If at least 10% of WNI Subscriber calls to FASTNET's POPs do
                    not connect due to factors within the reasonable control of
                    FASTNET during the course of a given month, and WNI finds it
                    necessary to redirect those Access calls to a different ISP,
                    then the Base Charges for that month shall be reduced by the
                    percentage of calls experiencing such difficulties as
                    compared to the total number of WNI Customer Access calls to
                    FASTNET's POPs minus 10%.

                    FOR EXAMPLE, IF 12% OF WNI'S CUSTOMERS CANNOT CONNECT TO
                    FASTNET OVER THE PERIOD OF ANY MONTH, THE TOTAL CHARGE TO
                    WNI FOR THAT MONTH WILL BE REDUCED BY 2%.

3.     END USER AGREEMENT

WNI agrees to have all of its Subscribers enter into an end user agreement (the
"End User Agreement") in substantially the form provided to FASTNET, the receipt
and adequacy of which FASTNET acknowledges.  In addition to it rights under
Section 6.1, FASTNET may deny or refuse connection or access to any FASTNET
dialup POP to any WNI Subscriber who violates the End User Agreement or notifies
FASTNET that it has a claim against FASTNET or that FASTNET is or might be
responsible to such customer for damages related to any services provided to
such customer through WNI.  WNI may amend the end user agreement once per
calendar quarter by giving FASTNET written notice of amendment.

4.     INDEMNIFICATION

WNI shall defend, indemnify, and hold harmless FASTNET against any claims, costs
or expenses (including reasonable attorneys' fees) arising out of, relating to
or resulting from any breach of this Agreement by WNI, or any use by WNI of
FASTNET's services in violation of this Agreement.  FASTNET shall defend,
indemnify, and hold harmless WNI against any claims, costs or expenses
(including reasonable attorneys' fees) arising out of, relating to or resulting
from any breach of this Agreement by FASTNET.

5.     TERM

The term of this Agreement shall commence on the Effective Date hereof and shall
continue until the date which is two (2) years from the date hereof, which term
shall be automatically renewed for additional one-year terms, provided that
neither party has delivered to the other party a written notice of intent not to
renew for the forthcoming term.  Such notice of intent shall be delivered not
less than 120 days in advance of the end of the current term.

6.     TERMINATION

       6.1    This Agreement may be terminated as follows:

              6.1.1 Either party may terminate this Agreement for cause,
                    without penalty, in the event that the other party breaches
                    any material terms of this Agreement. Prior to any
                    termination under this Section 6.1.1, the non-breaching
                    party shall first give the other party written notice of its
                    intent to terminate which shall specify the problem(s)
                    constituting cause. The other party will have thirty (30)
                    days from the date of receipt of such notice to correct the
                    problem. If the problem is not corrected within such period,
                    the non-breaching party may terminate this Agreement upon
                    notice to the breaching party.

              6.1.2 FASTNET may terminate this Agreement without penalty upon
                    ten (10) days written notice to WNI, if WNI permits a
                    violation of the acceptable use policy set forth in its End
                    User Agreement and does not act to remedy such violation
                    within seven (7) days after receiving written notification
                    of such violation from FASTNET.

              6.1.3 FASTNET may terminate this Agreement without penalty if any
                    amounts due and owing by WNI remain unpaid sixty (60) days
                    after the date of invoice and FASTNET has notified WNI that
                    said amounts are past due, 10 business days prior to
                    termination.

              6.1.4 Either party may terminate this Agreement for convenience
                    after giving the other party six (6)-month written notice.
                    In the event of any termination under this Section 6.1.4,
                    FASTNET will maintain service availability at least the
                    usage level of the immediately preceding full month for six
                    (6) months from the date notice is received by FASTNET.

              6.1.5 As provided by Section 7.

       6.2  The exercise of any right of termination under Section 6.1 shall
            be in addition to, and not in lieu of, any other rights and
            remedies of the nonbreaching party hereunder. Notwithstanding
            anything to the contrary in this Agreement, the provisions of
            Sections 4, 9, 10, 11, 12, 13, 14 and 15 shall survive the
            expiration or termination of this Agreement for any reason.

7.     TESTING

During the period of sixty (60) days following execution of this Agreement, both
parties shall use all commercially reasonable efforts to integrate their
respective networks to provide the connectivity described in Schedule C and
shall conduct testing to assure such

<PAGE>

connectivity. If either party shall reasonably declare the testing results to be
unsatisfactory at the conclusion of the sixty (60) day period, then the parties
shall have another twenty (20) days to correct the problem; and if such
correction is not completed to the mutual and reasonable satisfaction of the
parties within such time, then either party shall be entitled, upon written
notice to the other party, to terminate this Agreement without further liability
to either party. If no such notice is given within eighty (80) days of the
execution hereof, satisfactory completion of technical testing shall be
presumed, and the contract shall remain in full force and effect. Billing will
begin thirty (30) days after the termination of testing, at the rates described
in Schedule B. If testing is completed during the course of a month, the first
month's billing will be prorated to reflect the shortened month. Testing may be
declared complete before the 60 day testing period is complete if both parties
agree.

8.     FORECASTS

WNI shall not be required to provide expected usage forecasts to FASTNET.  WNI
shall use commercially reasonable efforts to provide FASTNET with advance
information as to marketing programs which WNI expects will materially impact
future loads, particularly concerning loads in FASTNET's geographical
locations/POPs.

9.     NO PUBLICITY

Neither party shall disclose the prices and terms of this Agreement, except for
disclosure in confidence to its employees and consultants, accountants,
attorneys, bankers, investors, potential investors, or as required by law.
Neither party shall publicize the existence of this Agreement without the
written consent of the other, and in the event of such agreement, all press
release materials shall be reviewed and approved by the other party prior to the
publication of such press release materials.

                                   SCHEDULE A

                            NETWORK INTEROPERABILITY

1.   FASTNET shall make its dial-up (Internet) network access facilities
     available to WNI's Subscribers via the public switched telephone network
     using circuit termination equipment which complies with current interface
     and modem standards (i.e. V.34 for 28,800 bps service, with extensions for
     33,600 speeds as available) and supports dial-in connection speeds of (at
     least) 28,800 bps. In addition, FASTNET will use equipment which supports
     PPP connections and PAP authentication in a manner which is compatible with
     WNI client and server software, which compatibility shall be ascertained
     during testing (Agreement section 7). FASTNET will notify WNI of changes in
     its modem and terminal server hardware and software in advance of making
     such changes and if WNI should determine that planned changes are not
     compatible with WNI systems and services, WNI may exercise its rights under
     section 6.1.1 of this Agreement.

2.   FASTNET shall provide to WNI telnet access with a login account on a Unix
     host computer attached to its network with telnet access and the ability to
     issue ping and traceroute commands from within FASTNET's network. If
     FASTNET does not have an available Unix host for telnet access, they shall
     identify one or more computers within it's network which will properly
     respond to ICMP requests and traceroute commands issued from other Internet
     locations outside of FASTNET's network.

3.   FASTNET shall operate a proxy server that can identify access by WNI
     Subscribers and forward login attempts from such Subscribers to WNI's
     Radius server for authentication, provided that WNI's Radius server can be
     reached through the Internet from FASTNET's network, or with dedicated
     lines between the parties.

4.   FASTNET shall operate a TCP/IP network that can link WNI's Subscribers who
     connect to FASTNET's dialup network access facilities to WNI's servers,
     provided WNI's servers can be reached through the Internet from FASTNET's
     network, or with dedicated lines between the parties.

5.   FASTNET shall provide WNI with applicable Radius software, as it is
     required for interoperability with FASTNET's Radius implementation. WNI
     will be responsible for any fees to third parties for licensing this
     software for the copies used by WNI. In connection with obtaining the
     source code for the Radius Software, WNI must agree to reasonable
     confidentiality and source code protection requirements of the owner of the
     Radius Software and FASTNET.

6.   FASTNET's network services shall maintain Radius server interoperability
     during the course of the contract.

7.   WNI agrees that it shall operate its own Radius server, which will perform
     user validation functions, and will maintain this server in a secure
     environment. WNI also

<PAGE>

     will maintain this server with reasonably current versions of the Radius
     protocols as provided by FASTNET.

8.   WNI agrees to assign each Subscriber a unique identification number for
     billing purposes, and to reasonably cooperate with FASTNET in establishing
     the structure of this identification number.

9.   WNI and FASTNET each agree to cooperate with the other in identifying and
     resolving any security infringements which involve WNI's Subscriber and
     FASTNET's network.

10.  WNI will impose inactivity time-outs on the WebTV boxes of a maximum of 15
     minutes. Inactivity time-outs disconnect the WNI Subscriber's box from
     FASTNET when the user has not sent any commands to the box for the
     specified period of time. In addition, WNI provides two other backup
     timeouts should the first timeout fail. FASTNET will not implement server
     side timeouts for WNI customers.

                                   SCHEDULE B

                        DIALUP NETWORK SERVICES PRICING

1.     FASTNET SHALL OFFER 2 DIFFERENT PRICING PLANS:

       1.1    "PER SUBSCRIBER" PRICING PLAN:  At the end of each month, FASTNET
              shall count the number of unique Per Subscriber IDs that were used
              to connect to the service during that month.  A Per Subscriber ID
              that was used in a prior month and that was not used in the month
              to be billed shall not be included.  WNI will then be billed an
              amount equal to this number of unique Per Subscriber IDs
              multiplied by a price per Subscriber defined as follows:

              Pricing shall be at $[*] per month.  A mutually agreed upon
              written pricing plan can replace this pricing at any time.

       1.2    "PER HOUR" PRICING PLAN:  At the end of each month, FASTNET shall
              calculate the cumulative numbers of hours spent on-line by WNI
              Subscribers that were identified by a Per Hour ID.  Each
              Subscriber's usage will be calculated in seconds and converted to
              hours with one decimal place, or in six minute increments.  WNI
              would then be invoiced an amount equal to this number of hours
              multiplied by a price per hour defined as $[*] per hour.  A
              mutually agreed upon written pricing plan can replace this pricing
              at any time.

       Whenever a WebTV box connects to FASTNET, WNI shall ensure that the
WebTV box uses an ID whose prefix identifies which pricing plan to use to bill
that connection (a "Per Subscriber ID" or "Per Hour ID," as applicable).

[*] We are seeking confidential treatment of these terms, which have been
    omitted. The confidential portion has been filed separately with the
    Securities and Exchange Commission.

                                   SCHEDULE C

                      CONNECTIVITY BETWEEN FASTNET AND WNI

FASTNET will provide transport via the Internet of WNI Subscriber traffic (IP
packets) between (1) FASTNET's network and WNI's network and server computers
and (2) between WNI Subscribers and all other generally reachable (non-WNI
network) IP networks comprising the Internet.  FASTNET will be responsible for
management of routing and performance of the provided transport from WNI's
customers through FASTNET's network connection to its carrier/ISP to insure
routing integrity and transport reliability.  FASTNET will exercise all
reasonable efforts within its control to insure that the average round trip
latency (measured by ICMP echo tests between FASTNET and WNI) is less than 100
milliseconds.  Further, FASTNET shall disclose to WNI the names and contact
information for the carrier(s) or ISP(s) through which it obtains Internet
backbone connectivity and/or packet exchange with other FASTNET/ISPs and the
interconnect location, routing arrangement and speed of such connection(s) in
order that WNI can adjust its connectivity and routing if needed to better
support FASTNET's transport obligation under the conditions of this paragraph.

Upon WNI's request, FASTNET shall also provide dedicated access into its network
for transport of WNI Subscriber traffic between FASTNET's network and WNI's
network and server computers.  The communication path between FASTNET and WNI
may be by way of common carrier, competitive access provider, CLEC, ISP or some
combination.  Terms for the implementation of such a solution shall be
negotiated at the time of WNI's request.  FASTNET agrees to provide suitable
floor/rack space and inside termination of the communication circuit(s) with
appropriate environmental facilities (HVAC and power with UPS), a router and
communication interface (router interface and DSU/CSU, etc.) compatible with
WNI's facilities at the far end of the path.  The connection and required
interfaces, at WNI's discretion, may be T-1 or fractional T-1 (with suitable
encoding and framing), DS-3 or fractional DS-3 (with Cisco HSSI router
interface) or Frame Relay, ATM (Asynchronous Transfer Mode) or SMDS at any
available speed.  FASTNET and WNI will manage and be responsible for the
operation and maintenance of the equipment at their respective ends of the
communication path.  FASTNET will cooperate with and accept guidance from WNI
for routing setup between the dedicated access path to WNI and the FASTNET's
other IP routes and shall permit WNI access to the SNMP MIB in the router at the
FASTNET end of the path for traffic and status monitoring and configuration
verification.

                              WEBTV NETWORKS, INC.

                         MUTUAL NON-DISCLOSURE AGREEMENT

This Non-Disclosure Agreement ("Agreement") is made and entered into as of 8/28,
1997 by WebTV Networks, Inc., having its principal place of business at 305
Lytton Avenue, Palo Alto, California 94301 (the "First Party") and You Tools
Corp. / FASTNET ("Second Party") with a principal place of business at 3864
Courtney Street, S-130, Bethlehem, PA  18017.

1. PURPOSE. The First Party and Second Party wish to explore a business
opportunity of mutual interest concerning each Party's business, operations,
proprietary technology, and products. In connection with this opportunity
certain trade secrets and business information proprietary to each Party and
which each Party considers Confidential Information (as defined below) may be
provided to one Party (the "Promisor") by the other Party (the "Discloser").
This Agreement is intended to allow both Parties to have open discussions
regarding Confidential Information, while still affording complete protection of
the Discloser's Confidential Information against disclosure or unauthorized use.
Written agreements regarding authorized disclosures or use of the Discloser's
Confidential Information may, but need not, be entered into between the Parties
in the future.

2. DEFINITION. "Confidential Information" means any Discloser proprietary
information relating to (i) the Discloser's proprietary technology and products,
including without limitation, technical data, trade secrets, know-how, research,
product plans, ideas or concepts, products, services, software, inventions,
patent applications, techniques, processes, developments, algorithms, formulas,
technology, designs, schematics, drawings, engineering, and hardware
configuration information (collectively, "Technical Information"), and (ii)
proprietary information relating to the Discloser's operations and business or
financial plans or strategies, including but not limited to customers, customer
lists, markets, financial statements and projections, product pricing and
marketing, financial or other strategic business plans or information
(collectively, "Business Information"), disclosed to Promisor by the Discloser,
either directly or indirectly, in writing, orally or by drawings or inspection
of samples, equipment or facilities. Confidential Information does not include
any of the foregoing items which (i) is known to Promisor at the time of the
disclosure to Promisor by the Discloser as evidenced by written records of
Promisor, (ii) has become publicly known and made generally available through no
wrongful act of Promisor, or (iii) has been rightfully received by Promisor from
a third party who is authorized to make such disclosures.

3. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. Promisor agrees not to use any
Confidential Information disclosed to it by the Discloser for its own use or for
any purpose except to carry out discussion concerning, and the undertaking of,
any business

<PAGE>

relationship between Promisor and the Discloser. Promisor will not disclose any
Confidential Information of the Discloser to third parties or to employees of
Promisor except to its employees who are required to have the information in
order to carry out the discussions of the contemplated business. Promisor will
have or has had its employees who have access to Confidential Information of the
Discloser sign a nondisclosure agreement in content substantially similar to
this Agreement and will promptly notify the Discloser in writing of the names of
each such employee upon the request of the Discloser at any time. Promisor
agrees that it will take all reasonable measures to protect the secrecy of and
avoid disclosure or use of Confidential Information of the Discloser in order to
prevent it from falling into the public domain or the possession of persons
other than those persons authorized hereunder to have any such Confidential
Information, which measures shall include the highest degree of care that
Promisor utilizes to protect its own Confidential Information of a similar
nature, but in any event not less than a reasonable degree of care. Promisor
agrees to notify the Discloser promptly in writing of any misuse or
misappropriation of Confidential Information of the Discloser which may come to
the Promissor's attention.

4. RETURN OF MATERIALS. Any materials or documents which have been furnished by
the Discloser to Promisor will be promptly returned to the Discloser,
accompanied by all copies of such documentation, after the business possibility
has been rejected or concluded, or at any time upon the Discloser's request. No
copies of the Discloser's Confidential Information may be made unless approved
in writing by the Discloser.

5. NO LICENSE. Nothing in this Agreement shall be construed as granting any
rights to Promisor under any patent or copyright, nor shall this Agreement be
construed to grant Promisor any rights in or to the Discloser's Confidential
Information, except the limited right to review such Confidential Information
solely for the purpose of determining whether to enter into the proposed
business relationship with the Discloser.

6. TERM. The foregoing commitments of Promisor shall survive any termination of
discussions between the Parties and shall continue (i) as to matters involving
"Business Information" for a period of three (3) years following the date of
this Agreement and (ii) as to Technical Information, until such Technical
Information is no longer required to be protected as set forth in the second
sentence of Paragraph 2 above.

7. MISCELLANEOUS. This Agreement shall be binding upon and for the benefit of
the undersigned Parties, their successors and assigns, provided that
Confidential Information of the Discloser may not be disclosed by means of any
assignment without the prior written consent of the Discloser. Failure to
enforce any provision of this Agreement shall not constitute a waiver of any
term hereof.

8. GOVERNING LAW. This Agreement shall be governed by and construed in
California and enforced in accordance with the laws of the State of California.
The federal and state courts within the State of California, Northern District,
shall have exclusive jurisdiction to adjudicate any dispute arising with the
Agreement or any disclosure by the Discloser

of its Confidential Information to Promisor, and Promisor hereby consents to
such jurisdiction.

9. REMEDIES. Promisor agrees that the obligations of Promisor provided herein
are necessary and reasonable in order to protect the Discloser and its business,
and Promisor expressly agrees that monetary damages alone may be inadequate to
compensate the Discloser for any breach of Promisor of its covenants and
agreements set forth herein. Accordingly, Promisor agrees and acknowledges that
any such violation or threatened violation will cause irreparable injury to the
Discloser and that, in addition to any other remedies that may be available in
law, in equity, or otherwise, the Discloser shall be entitled to obtain
injunctive relief against the threatened breach of this Agreement or the
continuation of any such breach by Promisor without the necessity of proving
actual damages.

10. ENTIRE AGREEMENT. This document contains the entire Agreement between the
Parties with respect to the subject matter contained herein and supersedes any
previous understandings or commitments, oral or written.
