occasions  within any six (6) month period,  Customer may cancel this  Agreement
without  incurring any  cancellation  charge.

3. Customer's End Users.

requirements promptly upon request of MCI WorldCom.  MCI WorldCom may change the
foregoing requirements for Customer's confirming orders and/or for notifying End
Users  regarding  the  transfer  charge  at any time in order  to  conform  with
applicable FGC and state regulations. Provided, however, Customer will be solely

network conforms with applicable FOC and state  regulations,  including  without
limitation,  the regulations established by the FCC with respect to verification
of orders for long distance service generated by telemarketing as promulgated in
47 C.F .R., Part 64, Subpart Kt Sec.64.1100 or any successor regulation(s).

(iii)  Customer  is not  certified  to provide  long  distance  services  in the
jurisdiction In which the ANI is located,  (iv) Customer is in material  default

implementing  reasonable verification processes determined by MCI WorldCom to be

by a LEG  (e.g.,  "PIC  freezes"),  or (vii) any other  circumstance  reasonably
determined  by MCI  WorldCom  which  could  adversely  affect  MCI  WorldCom  's
performance  under this Agreement or MCI WorldCom's  general ability to transfer
its other  customers or other end users to the MCI WorldCom  network,  including
without limitation, MCI WorldCom 's ability to electronically effect PIC changes
with the LECs.  In the event MCI  WorldCom  rejects an ANI,  MCI  WorldCom  will
notify Customer of its decision specifically describing the rejected ANI and the
reason(s) for rejecting that ANI, and will not incur any further liability under
this Agreement with regard to that ANI. Further, any ANI previously requested by

without  limitation,  excess  noise,  echo,  or loss of service.

4. Customer's Responsibilities.

     (A) Expedite  Charges In the event  Customer  requests  expedited  services
and/or changes to Service Requests and MCI WorldCom agrees to such request,  MCI
WorldCom will pass through the charges assessed by any supplying  parties (e.g.,
local access  providers)  for such  expedited  charges and/or changes to Service
Requests  involved  at the same  rate to  Customer.  MCI  WorldCom  may  further
condition  its  performance  of such  request  upon  Customer's  payment of such
additional charges to MCI WorldCom.

     (B)  Fraudulent  Calls  Customer  shall  indemnify  and hold  MCI  WorldCom

fraudulent is (or had been at the time of the call) an End User of such Switched
Services  through  Customer  or an end  user of the  Switched  Services  through
Customer's distribution channels.  Customer shall not be excused from paying MCI
WorldCom for Switched  Services  provided to Customer or any portion  thereof on
the basis  that  fraudulent  calls  comprised  a  corresponding  portion  of the
Switched Services.  In the event MCI WorldCom  discovers  fraudulent calls being
made (or reasonably believes fraudulent calls are being made), nothing contained
herein shall prohibit MCI WorldCom from taking  immediate action (without notice
to Customer) that is reasonably  necessary to prevent such fraudulent calls from
taking  place,  including  without  limitation,  denying  Switched  Services  to
particular AN Is or terminating Switched Services to or from specific locations.
Provided,  however,  nothing  contained herein will impose any obligation on MCI
WorldCom to take any action with  respect to  fraudulent  calls.

5. Charges and Payment Terms.

     (A) Payment MCI WorldCom billings for Switched Services  hereunder are made
on a monthly  basis (or such  other  basis as may be  mutually  agreed to by the

Services shall be billed at the rates set forth in the applicable Attachment(s).
Discounts, if any, applicable to the rates for certain Services are set forth in
the applicable Attachment(s).  Customer will pay all undisputed charges relative
to each MCI WorldCom  invoice for Switched  Services  within thirty (30) days of
the  invoice  date set forth .on each MCI  WorldCom  invoice to  Customer  ("Due
Date").  If payment is not  received by MCI  WorldCom on or before the Due Date,
Customer  shall  also  pay a late fee in the  amount  of the  lesser  of one and
one-half  percent  (1-1/2%) of the unpaid  balance of the  charges for  Switched

maximum lawful rate under applicable state law.

<PAGE>

     (C)  Modification  of Charges MCI WorldCom  reserves the right to eliminate
particular  Switched  Services  and/or modify  charges for  particular  Switched
Services (which charge  modifications  shall not exceed  then-current  generally
available  MCI WorldCom  charges for  comparable  services),  upon not less than
sixty (60) days prior notice to Customer,  which notice will state the effective
date for the charge modification. In the event MCI WorldCom notifies Customer of
the  elimination  of a  particular  Switched  Service  and/or an increase in the
charges,  Customer may terminate this Agreement without incurring a cancellation
charge (other than payment for Services  provided by MCI WorldCom up through the
effective  date of  cancellation)  only with respect to the Switched  Service(s)
affected  by  the  increase  in  charges.  In  order  to  cancel  such  Switched
Service(s),  Customer must notify MCI WorldCom, in writing, at least thirty (30)
days  prior to the  effective  date of the  increase  in  charges.  In the event
Customer cancels its subscription to a particular  Switched Service as described
in this  Subsection  5(C),  MCI WorldCom and Customer agree to negotiate in good
faith concerning Customer's minimum monthly commitment, if any, described in the
PET.

     (D) Billing  Disputes  Notwithstanding  the foregoing,  amounts  reasonably
disputed 'by Customer (along with late fees  attributable to such amounts) shall
apply but shall not be due and payable for a period of sixty (60) days following
the Due Date therefor,  provided Customer: (i) pays all undisputed charges on or
before  the  Due  Date,  (ii)  presents  a  written   statement  and  supporting
documentation of any billing  discrepancies to MCI WorldCom in reasonable detail
on or before the Due Date of the Invoice in question,  and (iii)  negotiates  in
good faith with MCI WorldCom for the purpose of  resolving  such dispute  within
said sixty (60) day period.  In the event such  dispute is mutually  agreed upon
and resolved in favor of MCI WorldCom,  Customer  agrees to pay MCI WorldCom the
disputed  amounts together with any applicable late fees within ten (10) days of
the resolution (the "Alternate Due Date"). In the event such dispute is mutually
agreed upon and  resolved in favor of Customer,  Customer  will receive a credit
for the disputed  charges in question and the applicable late fees. In the event
MCI WorldCom has responded to Customer's dispute in writing and the parties fail
to  mutually  resolve or settle the  dispute  within  such sixty (60) day period
(unless MCI  WorldCom  has agreed in writing to extend such period) all disputed
amounts together with late fees shall become due and payable, and this provision
shall not be construed to prevent  Customer from  pursuing any  available  legal
remedies. MCI WorldCom shall not be obligated to consider any Customer notice of
billing  discrepancies  which are received by MCI WorldCom  more than sixty (60)
days   following   the  Due  Date  of  the  invoice  in  question.

WorldCom's initial  satisfactory credit review and approval thereof which may be
conditioned upon terms specified by MCI WorldCom, including, but not limited to,
security  for  payments  due  hereunder  in the form of a cash  deposit or other
means. MCI WorldCom reserves the right to modify its requirements,  if any, with
respect to any security or other assurance provided by Customer for payments due
hereunder in light of Customer's  actual usage when compared to projected  usage
levels  upon  which  any  security  or  assurance  requirement  was  based.

     (B)  Creditworthiness If at any time there is a material adverse change, in
Customer's creditworthiness, then in addition to any other remedies available to
MCI WorldCom, MCI WorldCom may elect, in its sole discretion, to exercise one or

providing  Switched  Services pursuant to a Suspension Notice in accordance with

Customer to provide  Switched  Services  which MCI  WorldCom  may  otherwise  be
obligated to accept; and/or (iv) condition its provision of Switched Services or
acceptance of a Service  Request on Customer's  assurance of payment which shall
be a deposit or such other means to establish  reasonable  assurance of payment.

Alternate Due Date, if  applicable)  in any two (2)  consecutive  months;  (iii)
acquisition  of  Customer  (whether  in  whole  or by  majority  or  controlling
Interest) by an entity which is  Insolvent,  which is subject to  bankruptcy  or
insolvency  proceedings,  which  owes past due  amounts to MCI  WorldCom  or any
entity affiliated with MCI WorldCom or which is a materially greater credit risk
than  Customer;  or,  (iv)  Customer's  being  subject  to or  having  filed for
bankruptcy or Insolvency proceedings or the legal insolvency of Customer.

at least  five (5) days prior  written  notice and  opportunity  to cure  (which
notice may be given  instead of or in  conjunction  with the  Suspension  Notice

interest  MCI  WorldCom  may,  have,  to (i)  disconnect  all or any portion the
Switched Services being provided hereunder and/or terminate this Agreement: (ii)
withhold billing  information from Customer;  and/or (iii) contact the End Users
