ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a corporation to indemnify its directors,
officers, employees and agents against certain liabilities they may incur in
such capacities, including liabilities under the Securities Act of 1933, as
amended (the "Securities Act"), provided they acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation. The Registrant's Bylaws (Exhibit 3.2 hereto) require the Registrant
to indemnify its officers and directors to the fullest extent permitted by
Washington law.
 
     Section 23B.08.320 of the WBCA authorizes a corporation to limit or
eliminate its directors' liability to the corporation or its shareholders for
monetary damages for breaches of fiduciary duties, other than for (1) acts or
omissions that involve intentional misconduct or a knowing violation of law, (2)
improper declaration of dividends, or (3) transactions from which a director
derives an improper personal benefit. The Registrant's Amended and Restated
Articles of Incorporation (Exhibit 3.1 hereto) contain provisions limiting the
liability of the directors to the Registrant and to its shareholders to the
fullest extent permitted by Washington law.
 
     The above discussion of the WBCA and the Registrant's Bylaws and Amended
and Restated Articles of Incorporation is not intended to be exhaustive and is
qualified in its entirety by such statute, the Bylaws and the Amended and
Restated Articles of Incorporation, respectively.
 
     The Registrant maintains officers' and directors' liability insurance of on
its directors and officers.

ITEM 17.  UNDERTAKINGS.
 
     (a) Rule 415 Offering.
 
     The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this Registration Statement (or the most recent
        post-effective amendment thereof), which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this Registration Statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this Registration Statement
        or any material change to such information in this Registration
        Statement;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities as that time shall be deemed
     to be the initial bona fide offering thereof;
 
                                      II-9
<PAGE>   11
 
          (3) To remove from registration by means of post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) Indemnification for Liabilities
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.
 
     (c) Registration Statement Permitted by Rule 430A
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                         MARIA WIEGAND AND DAVE WIEGAND


         In consideration for the promises and covenants of MIDCOM
Communications Inc. and Maria Wiegand and Dave Wiegand made herein in connection

A.       Maria Wiegand

         "The term of this Agreement shall continue through December 29, 1999."

B.       Dave Wiegand

         Section 1 Consideration is amended by the addition of the following:
         "The payments of $10,000 per month payable to Wiegand for the months of
         December 1996 through December 1997 shall be paid in a lump sum
         pursuant to the terms and conditions of Section 4 of the Employment
         Agreement dated December 29, 1995 between Wiegand and MIDCOM and as a
         part of the severance payment defined in Section 2 (a) of the
         Settlement."

         Section 2 Term is amended to read in its entirety as follows:

         "The term of this Agreement shall continue through December 29, 1999."

         Subsection 3.3 (a) and (b) Restrictive Covenants are modified to read

         "(a) induce or attempt to induce any current employees of the ADNET
         DIVISION of MIDCOM to leave its employ but this restriction will not
         prohibit hiring or entering into business relationships with Scott
         White, Mike Whitman, Jean Reeves, or any other persons who have left
         the employ of the AdNet Division of MIDCOM on their own initiative and
         without any inducement on the part of Dave Wiegand."

         "(b) except in the regular course of any representation of MIDCOM as a
         consultant, directly or indirectly sell or market any long distance
         telecommunications services to any MIDCOM subscriber (or prospective
         customers whose identity was obtained by Wiegand through his employment
         or consulting relationship with MIDCOM or in an unauthorized manner)
         except that sales by other persons in any organization with which
         Wiegand is affiliated to MIDCOM subscribers shall not violate this
         provision if Wiegand does not provide any direct or indirect assistance
         in such sales."


                                       1
<PAGE>   2
New Subsection 4.3 is added as follows:

         "4.3 Arbitration. Except as to the remedies provided for in Section
4.2, injunctive relief, the parties agree that any dispute, difference or
disagreement in respect of this Non-Competition Agreement and the meaning and
construction hereof shall fully and finally be resolved by binding arbitration
conducted in accordance with the rules of the American Arbitration Association
before a single arbiter agreed upon by the parties. If a single arbiter cannot
be agreed upon within a reasonable time an arbitrator shall be selected in
accordance with the rules of the American Arbitration Association. Any judgment
upon any arbitration award may be entered in any court having jurisdiction
thereof. Venue for any arbitration matters shall be in Portland, Oregon.

New Section 13 is added as follows:

         "13.     Rights of First Refusal"

                  13.1 MIDCOM's Rights of First Refusal. If David Wiegand or any
entity or venture which he holds a majority equity or partnership interest of
50% ("the Wiegand Group") shall at any time prior to the first Release Event (as
defined in the Settlement) receive offers or series of offers from any
unaffiliated InterExchange Carrier or other providers of telecommunication
services ("Other Providers") giving the Wiegand Group opportunities to serve as
an independent distributor or certified reseller of long-distance
telecommunications services consisting of i) one plus, ii) 800, iii) calling
card or iv) frame relay services (individually "Covered Service" or jointly
"Covered Services") , the Wiegand Group shall use its best efforts to obtain
bona fide, written offers from such Other Providers and shall subject to
applicable legal or contractual restrictions submit exact copies of such offers
(which may have redacted confidential portions not required to enable MIDCOM to
assess rates and essential terms) to MIDCOM or, if the Wiegand Group is legally
or contractually prohibited from providing an exact copy of such an offer, the
Wiegand Group shall provide to MIDCOM a summary of the terms set forth in such
offer in as much detail as is permissible under applicable laws and contractual
restrictions which are sufficient to MIDCOM for it to make a knowledgeable
decision of its Rights of First Refusal. MIDCOM shall have the right,
exercisable by written notice delivered to the Wiegand Group within ten (10)
days from the date of delivery of each offer for a Covered Service to MIDCOM, to
meet the rates or commissions and the essential terms and conditions contained
in such offer (including without limitation price, payment terms, product mix,
geographic coverage, billing data and delivery accuracy, order provision
accuracy and timeliness, contract period, and commitment level, if any for all
Covered Services included in such offer for the same term specified therein
provided, however, that any service agreement between the parties will include a
right of either party to terminate such agreement in the event the other party
has materially breached its obligations thereunder and has failed to cure such
breach within fifteen (15) days after notice (or such shorter period as may be
provided in the applicable Other Provider offer).

   
                  13.2 Terms of Service Agreements. In connection with each
service agreement between MIDCOM and the Wiegand Group entered into pursuant to
this Section 13, (each a "Service Agreement") MIDCOM shall be required to (a)
provision [*]% of switched services within five (5) days of receipt of the
order therefor or otherwise within fourteen (14) days of receipt of the order
therefor, (b) provision [*]% of dedicated services within thirty (30) days of
receipt of the order therefor or otherwise within sixty (60) days of receipt of
the order therefor, and (c) provide to the Wiegand Group complete billing
information for all end users for which MIDCOM is providing services under a
wholesale service agreement within [*] days after the closing of each billing
cycle or period applicable to such end users if such records are available to
MIDCOM from any underlying interexchange telecommunications carrier. In
addition, no billing statement provided by MIDCOM to the Wiegand Group shall
(a) omit more than [*] percent ([*]%) of the records or files for any Covered
Services or customer of the Wiegand Group that should be included therein to
reflect all end user activity during the billing cycle or period to which the
statement is intended to relate, or (b) include errors affecting more than [*]
percent ([*]%) of the records or files or total dollar volume for any Covered
Services or customer of the Wiegand Group included in that statement to the
extent that MIDCOM is the party responsible for maintaining such records or
files. Each Service Agreement between MIDCOM and the Wiegand Group shall
further provide, upon any two occasions during the period thereof that each
party shall have the right to request amendments to any one or more terms of
the Service Agreement affecting a Covered Service or to add or delete a Covered
Service. If the other party does not accept such changes within sixty (60) days
then the change shall take effect but the other party may elect to delete the
affected Covered Service or remove customers therefrom provided further,
however, that in the case of any amendments requested by the Wiegand Group the
Wiegand Group shall have first received an offer (which may be solicited by the
Wiegand Group) from an Other Provider for such Covered Service and terms for
which amendments are being submitted, which shall be provided to MIDCOM in
accordance with the terms of Subsection 13.1.
    
   
    

<PAGE>   3
In case MIDCOM breaches any of its obligations under this Section 13, MIDCOM's
Rights of First Refusal with respect to any other offer made by Other Providers
for any Covered Service shall terminate. If MIDCOM does not exercise its Right
of First Refusal with respect to any offer or if MIDCOM cannot or is not willing
to meet the essential terms and conditions contained in any offer, the Wiegand
Group may after the waiting period provided for herein accept the offer of such
Other Providers pursuant to and on the terms of such offer, provided that if any
Other Provider's offer is not accepted within one hundred twenty (120) days
after delivery of such offer to MIDCOM, or there is a material change in the
terms of the transaction such that the transaction becomes more beneficial to
the Other Provider, MIDCOM shall again have continued Rights of First Refusal
provided in this Section 13. Notwithstanding anything herein to the contrary,
MIDCOM's right to perform services hereunder shall not apply if MIDCOM is not
able or not willing to provide all services offered by the Other Provider or if
any material term or condition of MIDCOM's services is less advantageous to the
Wiegand Group than the comparable term or condition of the Other Provider's
offer. Except as specifically set forth herein, the grounds for termination
between the Wiegand Group and MIDCOM shall in all material respects be the same
as those set forth in the agreements upon which the Rights of First Refusal are
predicated.  Furthermore, any performance requirements applicable to MIDCOM set
forth herein shall be minimum requirements subject to and replaced by any higher
service level set forth in the applicable Other Provider's Offer.

                  13.3 Period of Agreement. In the event the period of any
Service Agreement between MIDCOM and the Wiegand Group expires before the first
Release Event, Rights of First Refusal shall apply to all other offers for any
Covered Service from Other Providers received by the Wiegand Group prior to the
first Release Event, which shall be provided to MIDCOM in accordance with the
terms of Subsection 13.1. Notwithstanding anything herein to the contrary,
MIDCOM's rights under this Section 13 shall terminate immediately upon (1) the
date that Dave Wiegand owns less than three quarters of one percent (3/4%) of
MIDCOM's outstanding 

   
    


                                       3
<PAGE>   4
common stock and the Wiegands have disposed of more than seventy percent (70%)
of their combined current interests in MIDCOM common stock or options to acquire
such stock or, (2) MIDCOM files a plan of reorganization or a plan of
liquidation under Chapter 11 or Chapter 7 of the federal Bankruptcy Code or
voluntary or involuntary dissolution or liquidation proceedings are commenced by
or against the Company or the Company makes a general assignment for the benefit
of creditors of institutes or consents to a proceeding for appointment of a
receiver or custodian or similar officer.

                  13.4 Failure to Submit. A failure of the Wiegand Group to
submit offers to MIDCOM pursuant to Section 13 and the Wiegand Group's execution
of a definitive agreement with the Other Provider contrary to MIDCOM rights
under this Section 13 shall be deemed to constitute a breach of this
Non-Competition Agreement by Dave Wiegand entitling MIDCOM to the remedies set
forth in Section 4, but no breach by Dave Wiegand of his obligations hereunder
shall entitle MIDCOM to refuse to perform its obligations to Dave Wiegand under
the Stock Option Agreement between MIDCOM and Dave Wiegand dated November 25,
1996, which obligations are independent of this Agreement and shall remain in
effect notwithstanding any dispute between the parties hereunder.

                  13.5 Restrictions on the Parties. Neither party shall at any
time during the term of this Agreement or for six months thereafter use
confidential information such as a Customer List to market or provide any
services to the other party's customers.

         Except as specifically amended herein, all the remaining terms and
conditions of each of the Non-Competition Agreements of Maria Wiegand and Dave
Wiegand of December 29, 1995 respectively shall remain in full force and effect.

         DATED this 27 day of December, 1996.

                    AT&T/MIDCOM Confidential and Proprietary
   
    
<PAGE>   2
                THEREFORE, in consideration of the mutual promises contained
herein, the parties agree as follows:

        1.  New Agreement

            AT&T will file revisions to CT 969, in the form attached to this
Agreement as Attachment A. On the date such revisions become effective, and
without any further action being required, Customer's subscription to CT 969
will be discontinued without liability, according to the revised terms of CT
969, in conjunction with Customer's order for service under a separate Carrier
Agreement between AT&T and Customer (the "New Service"). If, however, such
Carrier Agreement is not effective as of the date the revisions to CT 969
become effective, the Customer's subscription to CT 969 will not be
discontinued without liability until the effective date of the Carrier
Agreement.

        2.  Payments to AT&T

            (a) AT&T and Customer agree that as of September 30, 1996, Customer
has paid the total amount owed to AT&T for charges billed through and including
July 1, 1996. (b) Customer will pay AT&T $3.8 million within 30 days after
Customer announces quarterly gross revenues in excess of $75 million or upon
completion of a Change in Control. For purposes of this Agreement, a Change in
Control occurs if, (1) as a result of a tender offer, fifty percent (50%) or
more of the outstanding shares of common stock of MIDCOM is acquired by another
person or entity, or (2) the shareholders of MIDCOM approve a merger involving
the conversion or exchange of fifty percent (50%) or more of the outstanding
shares of common stock of MIDCOM into other securities, cash or property (or
any combination thereof).

        3.  Existing Disputes
   

            AT&T and Customer acknowledge that bona fide billing disputes exist
between the parties in the amount of $1,117,247.00 as described in Attachment B
to this Agreement ("the Existing Disputes").
    

        4.  Arbitration

            With respect to the Existing Disputes, Customer or AT&T shall have
the right to commence an arbitration proceeding. The party choosing arbitration
shall submit the dispute(s) to the Center for Public Resources ("CPR"). The
arbitration shall be held in Chicago, Illinois and shall be conducted under the
then-current rules and supervision of the CPR. The Federal Arbitration Act, 9
U.S.C. Sections 1 to 16, will govern the arbitrability of all claims. The
arbitral decision and award shall be binding and judgment on the award may be
entered in any

                                       2

                    AT&T/MIDCOM Confidential and Proprietary

   
    

<PAGE>   3
court of competent jurisdiction. The arbitration will be conducted by a single
arbitrator who is knowledgeable in business information, commercial matters or
the telecommunications field, as applicable, except that either party may
require that the arbitration be conducted by a tribunal of three such
arbitrators by providing Notice of such a demand to the other party before a
single arbitrator is selected. The arbitrator(s) may not limit, expand or
otherwise modify the terms of this agreement and will not have authority to
award damages to either party beyond the limitations of liability provided in
this Agreement.

            The arbitrator may not expand the amount sought regarding the
applicable dispute beyond that specified in Section 3. The parties, their
representatives, other participants and the arbitrator shall hold the
existence, content and result of the arbitration in confidence. Each party
shall bear its own costs and expenses if arbitration occurs.

        5.  Transfer of Obligations

            The outstanding Customer obligations, not otherwise extinguished
under this Agreement, which have arisen or which may arise under the Former
Service shall be transferred to the New Service at such time as the New Service
Agreement is effective. Such obligations include all tariffed charges provided
that there are not shortfall or termination charges associated with CT 969 at
the time of termination of CT 969.

        6.  Releases

            The following releases are effective as of the initial service date
of the Carrier Agreement for the New Service:

            (a) Customer, on behalf of itself and its employees, agents,
shareholders, officers, subsidiaries, predecessors, affiliates, parent
corporations, if any, joint venturers, successors and assigns, heirs,
executors, administrators and trustees ("Customer Releasors"), hereby
discharges and releases AT&T and its past and present employees, agents,

1.3.    APPLICABILITY OF AT&T TARIFFS.

        AT&T's tariffs filed with the F.C.C. shall apply to the Services to the
extent provided in Attachment A.

1.4.    PROVISIONING.

        CUSTOMER is responsible for placing any orders as necessary for AT&T to
provision the Services. CUSTOMER shall provide provisioning information as is
required according to AT&T's standard ordering procedures applicable to
CUSTOMER.

1.5.    BILLING AND PAYMENT.

        (a)     CUSTOMER is liable for all amounts due to AT&T under this
Agreement. AT&T will provide to CUSTOMER a single monthly bill on magnetic tape
for each of the Services, except that, at AT&T's option, the billing for more
than one of the Services may be combined on a single monthly bill on magnetic
tape. Said bill or bills will be sent to one CUSTOMER location designated by
CUSTOMER.

        (b)     Payment of charges under this Agreement is due, and CUSTOMER's
obligation to pay such charges is enforceable, upon presentation of a bill to
CUSTOMER or CUSTOMER's designate. Payment shall be made to AT&T by electronic
funds transfer, or by such other payment method as the parties may agree in
writing. Except as provided in Section 1.5(c), payment shall be considered
timely if made within one month after the date of the bill.

        (c)     The following payment provisions will apply until such time as
CUSTOMER either establishes a record of timely payment for at least one year,
or posts a deposit (or other assurance of payment satisfactory to AT&T) equal
to three months' net charges, but in no event less than [*].

                (1)     Beginning October 21, 1996, and every Monday thereafter
        (or the next business day if the Monday is a holiday), CUSTOMER will
        submit to AT&T an estimated weekly payment (the "Weekly Payment") to be
        applied to CUSTOMER's account for Services provided under this
        Agreement.  Customer's failure to submit any Weekly Payment in full on
        or before the due date established may result in disconnection of
        service upon five days' prior written notice.

                (2)     The Weekly Payment for October 21, 1996 will be [*].
        The Weekly Payment thereafter shall be [*], subject to modification as 
        follows.  At least once every three months, AT&T, in consultation with
        CUSTOMER, shall determine CUSTOMER's average weekly charges for the
        three most recently-available billing months (based on net billed
        amounts, and taking disputed charges into account only to the extent
        deemed appropriate by AT&T).  If the then-effective Weekly Payment
        amount is more than ninety percent (90%) of such average weekly charges,
        AT&T shall establish a new Weekly Payment amount approximately equal to
        ninety percent (90%) of such average weekly charges.  If the
        then-effective Weekly Payment amount is less than ninety percent (90%)
        of such average weekly charges, AT&T may establish a new Weekly Payment
        amount approximately equal to ninety percent (90%) of such average
        weekly charges.  The new Weekly Payment amount will become effective ten
        (10) days after AT&T provides written notice to CUSTOMER of the new
        amount.  Except as provided in Section 1.5(c)(4) and 1.5(d), disputed
        charges shall not be withheld from the Weekly Payment amount.


                (3)     The Weekly Payments will be applied first against any
        amounts past due, and then against current charges.  A true-up payment
        will be due with the last Weekly

        Payment of each calendar month.  The true up payment will be equal to
        the sum of the amount shown as due on the DNS invoice dated the 29th of
        the prior calendar month and the SDN and Inbound Services invoices dated
        the 1st of the calendar month in which the Weekly Payment is made,
        subject to adjustment for disputes as described in Section 1.5(d).  If
        the sum of such amounts is negative (i.e., there is a net credit due to
        CUSTOMER) for two consecutive months, AT&T will adjust the amount of the
        Weekly Payment pursuant to Section 1.5(c)(2).

                (4)     If CUSTOMER requests a credit ????? account, CUSTOMER's
        Director of Revenue Accounting at AT&T shall review the account status
        with the AT&T District Manager responsible for collection of charges
        from CUSTOMER and apply reasonable and normal business standards to
        promptly determine whether or not the credit should be applied to
        CUSTOMER's account.  If the AT&T District Manager agrees in writing to
        reduce (in whole or in part) one or more Weekly Payments as a result of
        such a credit, then CUSTOMER may make Weekly Payments adjusted in the
        manner so specified by AT&T.

        (d)     If CUSTOMER provides to AT&T a written bona fide dispute of a
charge before payment is due for that charge, payment will be considered timely
if made within fifteen (15) days after AT&T sustains the charge as correct.
CUSTOMER may withhold payment of charges under this Section for any calls for
which AT&T has not provided standard call detail records on magnetic tape or
other electronic media (unless AT&T's failure to provide such records is
attributable to CUSTOMER); payment of such charges will be considered timely if
made within thirty (30) days after AT&T thereafter provides such call detail
records.  Payment by CUSTOMER of a disputed charge does not preclude CUSTOMER
from continuing to dispute

the charge, nor does acceptance by AT&T of a partial payment preclude AT&T from
collecting the unpaid amount (notwithstanding any restrictive endorsements).

        (e)     CUSTOMER shall be solely responsible for rendering bills to and
collecting charges from its own customers.  Failure of CUSTOMER to bill or
collect charges shall not excuse in whole or in part CUSTOMER's
responsibilities to AT&T under this Agreement, including but not limited to the
responsibility to render to AT&T timely payment of charges.

        (f)     If CUSTOMER does not make timely payment of any charge(s) other
than bona fide disputes, AT&T may apply a late payment charge equal to 1% of
such charge(s) for each whole month and pro rata for any partial month between
the date on which the payment would have been considered timely and the date on
which the payment is made to AT&T, except that if such charge is found to be in
excess of the maximum amount allowed by applicable payment charge shall be the
maximum amount allowed by applicable law.

        (g)     CUSTOMER is responsible for safeguarding the service from use
by ???? persons, and to pay all charges for use of the service by any persons
whether or not a CUSTOMER.

1.6     DEPOSITS.

        AT&T may at any time require CUSTOMER to furnish a deposit under the
same terms and conditions that apply to deposits under AT&T Tariff F.C.C. No. 1,
Section 2.5.6., as it exists on the Effective Date.

                            2.  USE OF THE SERVICES


2.1     RESALE OF SERVICES.

        (a)     CUSTOMER may (1) resell the Services directly (e.g., through
CUSTOMER's own employees, agents and/or independently contracted sales
representatives) to entities that will actually use the service (referred to in
this Agreement as "End Users") and/or (2) resell the Services directly to other
resellers for ultimate resale to End Users (which ultimate resale may but need
not be through one or more other intermediaries). All resellers and other
intermediaries in the sales chain between CUSTOMER (including its employees,
agents and independently contracted sales representatives) and an End User are
referred to in this Agreement as "Intermediate Resellers".

        (b)     AT&T has no relationship with CUSTOMER's End Users or
Intermediate Resellers under this Agreement and has no obligation to
communicate with, or provide support to CUSTOMER's End Users or Intermediate
Resellers. AT&T shall not use information provided by CUSTOMER in connection
with the provision of the Services in support of AT&T's own marketing efforts.

2.2     ABUSE OF THE SERVICES.

        The abuse of Service is prohibited. The following activities constitute
abuse:

        (a)     Using Service to make calls that might reasonably be expected
to frighten, abuse, torment, or harass another, or

        (b)     Using Service in such a way that it interferes unreasonably
with the use of Service or AT&T's network by others.

2.3.    FRAUDULENT USE OF THE SERVICES.

        The fraudulent use of, or the intended or attempted fraudulent use of
Service is prohibited. In any instance in which AT&T believes in good faith
that there is fraudulent use of Service, AT&T may, immediately and upon written
notice to the Customer, and without liability on the part of AT&T, restrict,
suspend or discontinue providing Service. In the event that Customer does not
provide to AT&T within five (5) business days of the temporary restriction of
service acceptable proof that said use has ceased and that appropriate measures
have been taken to prevent its recurrence, AT&T may immediately and without
further notice discontinue service and CUSTOMER shall be liable for a
Termination Charge as provided in Attachment A. If the event giving rise to the
right to restrict, suspend, or discontinue service is limited to one or more
specific locations, 800/888 numbers or calling cards, AT&T shall, to the extent
practicable, limit the restriction, suspension or discontinuance to those
locations, 800/888 numbers or calling cards. This Agreement does not obligate
AT&T to monitor, notify CUSTOMER about, or prevent fraudulent use of Service.
The following activities constitute fraudulent use:

        (a)     Using Service to transmit any message or code, locate a person,
or otherwise give or obtain information, without payment for Service (AT&T shall
not apply this provision to CUSTOMER differently than it generally applies to
comparable provision of AT&T Tariff F.C.C. No. 1 to other customers);

        (b)     Using or attempting to use Service with the intent to avoid the
payment, either in whole or in part, of any charges by any means or device;

        (c)     Using Service to carry calls that originate on the network of a
facilities-based interexchange carrier other than AT&T and terminate
disproportionately to locations for which

the cost to AT&T of terminating switched access is above the average cost of
terminating switched access, based on the published access tariffs of local
exchange companies; or

        (d)     Using the Services to carry calls that originate on the network
of a facilities-based interexchange carrier other than AT&T and terminate
disproportionately to locations for which the cost to AT&T of terminating
switched access is above AT&T's average cost of terminating switched access.

2.4.    INTERFERENCE, IMPAIRMENT OR IMPROPER USE.

        Customer may not use Service in any manner that subjects AT&T personnel
or non-AT&T personnel to hazardous conditions or results in immediate harm to
the AT&T network or other AT&T services. In any instance in which AT&T believes
in good faith that Service is being used in such manner, AT&T may immediately
restrict Service on a temporary basis. In such cases, AT&T will make a
reasonable effort to give the Customer prior notice. In the event that Customer
does not provide to AT&T within five (5) business days of the temporary
restriction of service acceptable proof that said use has ceased and that
appropriate measures have been taken to prevent its recurrence, AT&T may
immediately and without further notice terminate service and CUSTOMER shall be
liable for a Termination Charge as provided in Attachment A.

                          3.  TERMINATION OF AGREEMENT

3.1.    TERMINATION FOR MATERIAL NON-COMPLIANCE.

        If either party fails to comply with one or more of the material terms
and conditions of this Agreement, the other party may provide written notice of
such failure to the party in noncompliance and such party shall have ninety
(90) days following receipt of such notice to cure the noncompliance. If such
cure is not demonstrated to the reasonable satisfaction of the party

claiming the noncompliance within the ninety (90) day period, such party may
immediately terminate without liability this Agreement and the Services
provided hereunder upon written notice to the party in noncompliance provided
within sixty (60) days after the end of the cure period. In the event of a
termination under this Section, CUSTOMER shall be liable for a Prorated
Shortfall Charge to the extent provided in Attachment A. This Section shall not
apply to a termination for nonpayment.

3.2.    TERMINATION FOR NONPAYMENT.

        Except as otherwise provided in Section 1.5(d), if CUSTOMER fails to
make payment of charges due under this Agreement, AT&T may deny and/or restrict
the Services upon at least five (5) days' prior written notice to CUSTOMER.
Upon payment of all such charges, the denial and/or restriction of the Services
will be removed, except that if AT&T denies and/or restricts the Services for
nonpayment and CUSTOMER fails to pay the charges that gave rise to the denial
of Services within fifteen (15) days after the date on which such denial of
Services began, AT&T may immediately terminate without liability this Agreement
and the Services provided hereunder. In the event of a termination under this
Section of the entire Agreement, CUSTOMER shall be liable for a Termination
Charge as provided in Attachment A.

3.3.    TERMINATION FOR BREACH OF WARRANTY BY CUSTOMER.

        If at any time during the term of this Agreement CUSTOMER is in
material noncompliance with any of its Warranties under this Agreement, AT&T
may provide written notice of such non-compliance to CUSTOMER and CUSTOMER
shall have thirty (30) days following receipt of such notice to cure such
non-compliance. If such cure is not demonstrated to the reasonable satisfaction
of AT&T within the thirty (30) day period, AT&T may immediately terminate this
Agreement and the Services provided hereunder without liability upon written

shall be liable for a Termination Charge as provided in Attachment A.

                4.      LIMITATIONS OF LIABILITY AND INDEMNIFICATIONS

4.1.    LIMITATIONS OF LIABILITY.

        (a)     AT&T's liability, if any, for any claim or suit by CUSTOMER for
damages associated with the installation, provision, termination, maintenance,
repair or restoration of any of the Services shall not exceed an amount equal
to the charge under this agreement for the affected service for the period
during which the service was affected.  Any liability for damages shall be in
addition to any credit allowance that may otherwise be due.

        (b)     IN NO EVENT SHALL AT&T OR CUSTOMER BE LIABLE TO EACH OTHER IN
CONNECTION WITH THE INSTALLATION, PROVISION, TERMINATION, MAINTENANCE, REPAIR,
RESTORATION, USE OR RESALE OF THE SERVICES FOR INDIRECT, INCIDENTAL,
CONSEQUENTIAL, RELIANCE OR SPECIAL DAMAGES, INCLUDING WITHOUT LIMITATION
DAMAGES FOR LOST PROFITS OR DIMINISHED BUSINESS VALUE, REGARDLESS OF THE FORM
OF ACTION WHETHER IN CONTRACT, INDEMNITY WARRANTY, STRICT LIABILITY OR TORT,
INCLUDING WITHOUT LIMITATION NEGLIGENCE OF ANY KIND WHETHER ACTIVE OR PASSIVE.

        (c)     AT&T is not liable for damages caused by service, channels, or
equipment which it does not furnish.

        (d)     Nothing in this Section shall limit either party's liability
for damages to individuals or their estates for bodily injury or death
proximately caused by that party's negligence. The limitations of liability set
forth in this Agreement shall survive failure of an exclusive remedy.

4.2     INDEMNIFICATIONS.

        (a)     AT&T shall be indemnified, defended, and held harmless by
CUSTOMER against all claims, losses, or damages awarded, to the extent that
they arise from the use of the Services, regardless of the form of action,
whether in contract, tort (including AT&T's active or passive negligence),
warranty, or strict liability, involving:

                (1)     Claims for libel, slander, invasion of privacy, or
        infringement of copyright arising from any communication not initiated
        by AT&T or its agent;

                (2)     Claims for patent infringement arising from combining or
        using the Services in connection with facilities or equipment furnished
        by others, provided that such claim would not have arisen if the
        Services had not been combined or used in connection with facilities or
        equipment furnished by others;

                (3)     Claims arising out of the use of the Services in an
        explosive atmosphere;

                (4)     Claims brought against AT&T by any of CUSTOMER's
        Intermediate Carriers or End Users related to the Services provided to
        CUSTOMER under this Agreement.

        (b)     CUSTOMER shall be indemnified, defended and held harmless by
AT&T against all claims, losses or damages awarded, to the extent that they
arise from use of the Services, regardless of the form of action, whether in
contract, tort (including CUSTOMER's active or passive negligence), warranty,
strict liability, intellectual property infringement or

misappropriation involving claims of patent, copyright, trademark or trade
secret infringements arising solely from the use of the Services.

        (c)     If, in connection with any claim, lawsuit, or demand brought by
a third party against either party (the "Indemnified Party"), the Indemnified
Party asserts it is entitled to indemnification and defense from the other party
(the "Indemnifying Party") pursuant to this Agreement, the Indemnified Party
shall provide prompt written notice to the Indemnifying Party of such claim,
lawsuit or demand, and shall tender the defense of such claim, lawsuit, or
demand to the Indemnifying Party.  The Indemnifying Party shall cooperate in
every reasonable manner with the defense or settlement of such claim, lawsuit,
or demand.  The Indemnifying Party shall not be liable for settlements by the
Indemnified Party of any such claim, demand, or lawsuit unless the Indemnifying
Party has approved the settlement in advance or unless the defense of the claim,
demand, or lawsuit has been tendered to the Indemnifying Party, in writing, and
the Indemnifying Party has failed promptly to undertake the defense.

using AT&T's corporate or trade names, logos, trademarks, service marks, trade
dress or other symbols that serve to distinguish AT&T from its competitors in a
manner inconsistent with Section 6.1. of this Agreement (an "Inconsistent Use"),
AT&T shall provide notice of such Inconsistent Use to CUSTOMER.  The exclusive
means and remedy for settling any dispute between the parties as to whether a
particular use constitutes an Inconsistent Use shall be an arbitration conducted
under the Non-Administered Arbitration Rules (the "Rules") of the CPR Institute
for Dispute Resolution

(the "CPR Institute"), except as otherwise provided in this Agreement.  In the
case of a conflict between this Agreement and the Rules, this Agreement will
govern.

        (b)     If AT&T provides notice to CUSTOMER of an Inconsistent Use, and,
within 30 days after the receipt of such notice, CUSTOMER either (1) cures the
Inconsistent Use or takes appropriate commercially reasonable efforts to prevent
an Intermediate Reseller from continuing such use (which efforts shall include
ceasing to provide service to the Intermediate Reseller, if necessary), (2)
demonstrates that no Inconsistent Use occurred, or (3) demonstrates that no
person responsible for the Inconsistent Use was either CUSTOMER, an Affiliate of
CUSTOMER, an Intermediate Reseller, or an employee, agent or independently
contracted sales representative of any of them, then there shall be no loss of
discount arising out of the use that gave rise to the notice.  If CUSTOMER
thereafter seeks to contest AT&T's determination that the use was an
Inconsistent Use, CUSTOMER must institute an arbitration under the Section.  If
CUSTOMER does not obtain a ruling in such arbitration that the use was not an
Inconsistent Use, CUSTOMER shall be precluded from repeating such use (and shall
take appropriate, commercially reasonable measures to ensure that no
Intermediate Reseller repeats such use).

        (c)     If AT&T provides notice to CUSTOMER of an Inconsistent Use, and
CUSTOMER does not avoid the withholding of discount by accomplishing one of the
steps described in (1) through (3) of Section 6.2(b) within the specified
period, the discounts and credits set forth in Attachment A will not apply
beginning as of the date AT&T's notice is given and ending as of the date that
CUSTOMER accomplishes one of the steps described in (a) through (c) of Section
6.2(b).  Any such suspension of discounts shall not relieve CUSTOMER from its
obligations to comply with any other conditions contained in this Agreement.

        (d)     If CUSTOMER seeks to contest AT&T's determination that the use
was an Inconsistent Use, CUSTOMER shall institute an arbitration as provided
below.  If CUSTOMER does not institute such an arbitration, CUSTOMER shall be
precluded from contesting AT&T's determination that the use was an Inconsistent
Use.  If the Arbitrator decides that the use giving rise to the notice was not
an Inconsistent Use, any discounts that were not applied as a result of the use
will be restored and applied to CUSTOMER's account as a credit.

        (e)     To institute an arbitration under this subsection, CUSTOMER
shall submit the dispute to a tribunal of three arbitrators to be selected
jointly by the parties, or, at the option of either party, to be selected by the
procedures established under the then-current rules of the CPR Institute for the
selection of arbitrators.  Each of the arbitrators shall be an attorney with not
less than ten (10) years experience in the practice of trademark law.  The
parties shall cooperate in good faith to achieve a prompt resolution of the
arbitration.  In the event that the parties, in consultation with the CPR
Institute, determine that a panel of three qualified arbitrators cannot be
appointed pursuant to this procedure, the parties will work in good faith, in
consultation with the CPR Institute, to implement an alternative process for
appointing a panel of three qualified arbitrators.

        (f)     The arbitration panel will determine whether the use that gave
rise to the notice constitutes an Inconsistent Use, and the parties will comply
with such interpretation.  Judgment on the award of the arbitration panel may be
entered in any court or administrative body having jurisdiction.

        (g)     Initially, all administrative fees of the CPR Institute and all
Arbitrator compensation ("Arbitration Fees") shall be borne equally by CUSTOMER
and AT&T.  At the conclusion of the arbitration, the arbitration panel shall
award to the prevailing party (as

determined by the arbitration panel), the Arbitration Fees paid by such party.
Each party shall bear the expense of its own counsel, experts, witnesses,
preparation and presentation of proofs, travel, and other out-of-pocket
expenses. 

6.3     NO PATENT OR SOFTWARE LICENSE.

        No license under patents or software copyrights is granted by AT&T or
shall be implied or arise by estoppel, with respect to the Services provided
under this Agreement.

6.4     CONFIDENTIALITY.

        (a)     Information furnished or disclosed by one party or its agent or
representative (the "Disclosing Party") to the other party or its agent or
representative (the "Receiving Party") in connection with or in contemplation
of this Agreement, or relating to current or anticipated voice and data
telecommunications needs of CUSTOMER (including but not limited to lists of
CUSTOMER's customers and/or End Users, other information about CUSTOMER's
customers and/or End Users, proposals, contracts, tariff and contract drafts,
specifications, drawings, network designs and design proposals, pricing
information, strategic plans, computer software and documentation, and other
technical or business information related to current and anticipated AT&T or
CUSTOMER products and services), shall be deemed "Confidential Information".

        (b)     If such information is in written, graphic or other tangible
form, it shall be deemed Confidential Information only if it is indicated by
appropriate markings or statements to be confidential or proprietary, provided,
however, that all written or oral pricing, contract, and tariff proposals
exchanged between the parties (including proposals exchanged in contemplation
of this Agreement) shall be deemed Confidential Information, whether or not
expressly indicated by markings or statements to be confidential or
proprietary.

                                     - 19 -


        (c)     Confidential Information shall be deemed the property of the
Disclosing Party and shall be returned to the Disclosing Party upon request
either at the end of the Term or at an earlier time if the information is no
longer needed for the purposes described in subsection (e) below.

        (d)     The terms and conditions of this Agreement shall be deemed
Confidential Information as to which each party shall be both a Disclosing
Party and a Receiving Party.  Information that was previously known to the
Receiving Party free of any obligation to keep it confidential or is
independently developed by the Receiving Party shall not be deemed Confidential
Information.  The Receiving Party shall not be required to hold in confidence
any Confidential Information that is made public by the Disclosing Party or a
third party.

        (e)     A Receiving Party shall hold all Confidential Information in
confidence during the Term and for a period of twelve (12) months following the
termination of this Agreement.  During that period, the Receiving Party: (1)
shall use such Confidential Information only for the purposes of evaluation,
negotiation, discussion between the parties, preparation of proposals, provision
or use of AT&T products and/or services and otherwise carrying out the intent of
this Agreement; (2) shall reproduce such Confidential Information only to the
extent necessary for such purposes; (3) shall restrict disclosure of such
Confidential Information to such of its employees or its Affiliate's employees
as have a need to know such information for such purposes only; (4) shall advise
any employees to whom such Confidential Information is disclosed of the
obligations assumed in this Agreement; (5) shall not disclose any Confidential
Information to any third party (not including disclosure to an employee of an
Affiliate pursuant to (3)) without prior written approval of the Disclosing
Party except as expressly provided in this Agreement; and (6) shall use at least
the same degree of care as it uses with regard to its own proprietary or


                   AT&T/CUSTOMER CONFIDENTIAL AND PROPRIETARY             DRAFT

<PAGE>   24
                                     - 20 -

confidential information to prevent the disclosure, unauthorized use or
publication of Confidential Information.

        (f)     In the absence of a contrary instruction by a party, such
party's Affiliates, and the agents and employees of its Affiliates, shall be
deemed agents of such party for purposes of receipt or disclosure of
Confidential Information.  Accordingly, any receipt or disclosure of
Confidential Information by a party's Affiliate, or by an agent or employee of
such Affiliate, shall be deemed a receipt or disclosure by the party.

        (g)     CUSTOMER may disclose Confidential Information to a person or
entity (other than a direct competitor of AT&T) retained by CUSTOMER to provide
advice, consultation, analysis, legal counsel or any other similar services
("Consulting Services") in connection with this Agreement or the service
provided hereunder (such person or entity hereinafter referred to as
"Consultant") only with AT&T's prior permission and only after CUSTOMER
provides to AT&T a copy of a written agreement by such Consultant (in a form
satisfactory to AT&T): (a) to use such Confidential Information only for the
purpose of providing Consulting Services to CUSTOMER, and (b) to be bound by
the obligations of a Receiving Party under this Agreement with respect to such
Confidential Information.

        (h)     A Receiving Party may disclose Confidential Information if such
disclosure is in response to an order or request from a court, the FCC or other
regulatory body; provided, however, that before making such disclosure, the
Receiving Party shall first give the Disclosing Party reasonable notice and
opportunity to object to the order or request, and/or to obtain a protective
order covering the Confidential Information to be disclosed.  If the FCC
determines that legal requirements, including the Communications Act of 1934,
as amended, or the regulations promulgated thereunder, require the filing of
this Agreement with the Commission, or

<PAGE>   25
                                     - 21 -


if the FCC (or a state regulatory entity with applicable jurisdiction)
otherwise requires the filing of this Agreement pursuant to authority granted
by law or regulation, the party required to make with such filing shall file
the Agreement to the extent required and each party to this Agreement shall
request confidential treatment in connection with such filing.

        (i)     In the event of a breach or threatened breach by a Receiving
Party or its agent or representative of the terms of this Section, the
Disclosing Party shall be entitled to an injunction prohibiting such breach in
addition to such other legal and equitable remedies as may be available to it
in connection with such breach.  Each party acknowledges that the Confidential
Information of the other Party is valuable and unique and that the use or
disclosure of such Confidential Information in breach of this Agreement will
result in irreparable injury to the other party.

                             7. DISPUTE RESOLUTION

        Except as provided in Section 6.2, if a dispute arises between the
parties relating to this Agreement or to the Services provided under this
Agreement, or to the provision, use, sale, or resale of the Services (a
"Dispute"), the parties will use good faith efforts to resolve the Dispute
promptly and fairly by negotiation.  If the parties are unable to resolve the
Dispute through negotiation, the parties shall follow the dispute resolution
procedures provided in this Section.

7.1     MEDIATION.

        If the parties are unable to resolve a Dispute by negotiation, the
parties shall submit it to mediation conducted by a mediator to be selected
jointly by the parties or, at the option of either party, to be selected by the
procedures established under the then-current rules of the CPR Institute for
the selection of a mediator.  The parties, their representatives, other
participants and the mediator shall hold existence, content and result of the
mediation in confidence.  The


                   AT&T/CUSTOMER CONFIDENTIAL AND PROPRIETARY              DRAFT
<PAGE>   26
                                     - 22 -

mediation shall conclude at such time as either party (or the mediator) notifies
the other party (or, for the mediator, both parties) in writing that the parties
are at an impasse and that continued efforts at mediation are unlikely to be
productive.

7.2.    ARBITRATION.

        (a)     If a Dispute in which the total amount in controversy (based on
the written positions taken by the parties in the course of mediation) is ten
million dollars ($10,000,000) or less, or any Dispute (regardless of the amount
in controversy) regarding the payment, nonpayment or applicability of charges
(including shortfall or termination charges), is not successfully resolved by
negotiation or mediation, it shall be subject to binding arbitration under the
then-current Rules and supervision of the CPR Institute.  The arbitration will
be held in Chicago, Illinois.  The Federal Arbitration Act, 9 U.S.C. Sections 1
to 16, not New York law, will govern the arbitrability of all claims.  The
arbitral decision and award will be final and binding, and either party may
enter it in any court with jurisdiction.

        (b)     The arbitration will be conducted by a single arbitrator who is
knowledgeable in business information, commercial matters or the
telecommunications field, as applicable, except that either party may require
that the arbitration be conducted by a tribunal of three such arbitrators by
providing written notice of such a demand to the other party before a single
arbitrator is selected.  The arbitrator(s) may not limit, expand or otherwise
modify the terms of this Agreement and will not have authority to award damages
to either party beyond the limitations of liability provided in this Agreement.

        (c)     Each party will bear its own attorney's fees and related costs
and expenses associated with the arbitration.  The parties will pay the
arbitrator(s) fees and other similar costs and expenses of the arbitration as
the Rules provide.

<PAGE>   27
                                     - 23 -

        (d)     The parties, their representatives, other participants and the
arbitrator(s) shall hold the existence, content and result of the arbitration
in confidence except that the prevailing party shall have the right to enter
the arbitration award in a court of competent jurisdiction if such entry is
necessary to enforce the terms of the award.

        (e)     Neither party may bring a legal proceedings before a court or
administrative body a case in court in connection with a Dispute subject to
this Section 7.2.  If a party disregards this restriction, files such a legal
proceeding, and fails to dismiss it promptly upon being notified of this
provision, that party will pay the other party's costs and expenses, including
attorney's fees, incurred after the notice in defending the legal proceeding.

7.3     COURT PROCEEDINGS.

        If a Dispute not subject to Section 7.2 is not successfully resolved by
negotiation or mediation, it may be the subject of legal proceedings brought
before a court or administrative body having jurisdiction over the Dispute, and
will be submitted to arbitration only by written agreement of the parties.


                        8.      MISCELLANEOUS TERMS AND CONDITIONS.

8.1     COMBINATION WITH OTHER SERVICES OR OFFERS.

        This Agreement may not be used in combination with any other AT&T
Carrier Agreement, AT&T Contract Tariff, AT&T Tariff, promotions or other
offerings or pricing arrangements for any AT&T services.

8.2     ASSIGNMENT AND DELEGATION.

        Neither party may assign its rights under this Agreement, in whole or
in part, to a third party (other than an Affiliate of the assigning party),
without the express prior written consent of


                   AT&T/CUSTOMER CONFIDENTIAL AND PROPRIETARY              DRAFT
<PAGE>   28
                                     - 24 -


the other party, which consent will not be unreasonably withheld.  CUSTOMER may
delegate its obligations under this Agreement without the consent of AT&T, but
CUSTOMER shall remain liable for the performance of all such obligations
notwithstanding any such delegation.  This provision shall not restrict
CUSTOMER's right to resell the Service.  No resale of the Service, assignment of
rights, or delegation of duties shall release the original party from its
obligations under this Agreement.

8.3.    AFFILIATE.

        As used in this Agreement, an entity is an "Affiliate" of a party if
such entity directly or indirectly controls, is controlled by, or is under
common control with such party.

8.4.    INDEPENDENT PARTIES.

        The employees and agents of either party to this Agreement are solely
the employees or agents of that party, and not employees or agents of the other
party.  Neither party is responsible for the employment, control, or conduct of
the other party's employees.  AT&T's relationship with CUSTOMER, and CUSTOMER's
relationship with AT&T, under this Agreement will be that of an independent
contractor, and nothing herein will be construed to constitute either party (or
any of its Affiliates, employees, or agents), an employee, agent, fiduciary,
joint venturer or partner of the other party.

8.5.    ACKNOWLEDGEMENT OF RIGHT TO COMPETE.

        CUSTOMER acknowledges and understands that it remains at all times
solely responsible for the success and profits of its business.  AT&T makes no
promises, warranties or representations regarding CUSTOMER's business success or
prospects of business success in connection with the provision of the Services.
CUSTOMER acknowledges and understands that


                   AT&T/CUSTOMER CONFIDENTIAL AND PROPRIETARY             DRAFT
<PAGE>   29
                                     - 25 -


AT&T will continue to market AT&T services directly to the public (including
actual and potential End Users, Intermediate Resellers, and competitors of
CUSTOMER) and that such marketing will from time to time bring AT&T into direct
or indirect competition with CUSTOMER.  CUSTOMER acknowledges and understands
that nothing in this Agreement restricts in any way the rights of AT&T to engage
in competition with CUSTOMER or to market its services to competitors of
CUSTOMER.

8.6.    NO THIRD-PARTY BENEFICIARIES.

        This Agreement does not create any claim or right of action, nor is it
intended to confer any benefit on any third party, including but not limited to
any End-User or Intermediate Reseller.

8.7.    ACCESS TO CUSTOMER'S PREMISES.

        The Customer is responsible for arranging premises access at any
reasonable time so that AT&T personnel may install, repair, maintain, inspect or
remove Service components.  Premises access must be made available at a time
mutually agreeable to the Customer and AT&T.

8.8.    NETWORK EQUIPMENT.

        AT&T shall retain title to all of its network equipment and facilities
used to provide Services under this Agreement.

8.9.    FORCE MAJEURE.

        Neither party nor its Affiliates, subsidiaries, subcontractors, or
parent corporation shall be liable in any way for delay, failure in performance,
loss or damage due to any of the following: fire, strike, embargo, explosion,
power blackout, earthquake, volcanic action, flood, war, water, the elements,
labor disputes, civil or military authority, acts of God, acts of the public
enemy, inability to secure raw materials, inability to secure products, acts or
omissions of carriers, or

other causes beyond its reasonable control, whether or not similar to the
foregoing; provided, however, that any failure or inability by CUSTOMER to
resell Services provided under this Agreement or to collect payment from its
Intermediate Resellers or End-Users shall not excuse CUSTOMER from performing
its obligations under this Agreement.

8.10.   LOSS.

        CUSTOMER is liable to AT&T for the replacement cost of AT&T-provided
equipment installed at CUSTOMER's premises in the event of loss of said
equipment for any reason, including but not limited to theft, but not including
loss caused by a defect in the equipment itself.

8.11.   NOTICES.

        Any notice to the other party under this Agreement shall be given in

        This Agreement may be modified only by a writing signed by authorized
