         WHEREAS,  BellSouth  is a  local  exchange  telecommunications  company
authorized  to provide  telecommunications  services  in the states of  Alabama,
Florida,  Georgia,  Kentucky,  Louisiana,  Mississippi,  North  Carolina,  South
Carolina and Tennessee; and

         WHEREAS,  Colmena is or seeks to become an  alternative  local exchange
telecommunications  company  ("CLEC")  authorized to provide  telecommunications
services  in the  states of  Alabama,  Florida,  Georgia,  Kentucky,  Louisiana,
Mississippi, North Carolina, South Carolina, and Tennessee; and

         WHEREAS,  upon the execution of this Resale  Agreement  between Colmena
and BellSouth,  the agreement between Business Technology Systems and BellSouth,
dated  October 8, 1997,  will become null and void in its  entirety  having been
superceded  by the  execution  of this newly  negotiated  agreement  between the
Parties; and

         WHEREAS,  the  Parties  wish to resell  BellSouth's  telecommunications
services and/or  interconnect  their  facilities,  purchase network elements and
other services, and exchange traffic specifically for the purposes of fulfilling
their obligations pursuant to sections 251 and 252 of the Telecommunications Act
of 1996 ("the Act").

         NOW THEREFORE,  in  consideration  of the mutual  agreements  contained
herein BellSouth and Colmena agree as follows:

1.        Purpose

          The  Parties  agree that the  rates,  terms and  conditions  contained

          have  offered  telecommunications  services to the public in any state
          within  BellSouth's  region until such time as it has ordered services
          for resale or interconnection facilities for the purposes of providing
          business and/or residential local exchange service to customers

          Georgia,  Kentucky,  Louisiana,  Mississippi,  North  Carolina,  South
          Carolina, and Tennessee.  If as of the expiration of this Agreement, a
          Subsequent  Agreement  (as defined in Section 2.2) below) has not been
          executed  by  the  Parties,   this  Agreement   shall  continue  on  a
          month-to-month basic while a Subsequent Agreement is being negotiated.
          The Parties'  rights and  obligations  with respect to this  Agreement
          after expiration shall be as set forth in Section 2.4 below.

        2.2    The  Parties  agree that by no later than one  hundred and eighty
          (180)  days  prior to the  expiration  of this  Agreement,  they shall
          commence negotiations with regard to the terms,  conditions and prices
          of resale and/or local  interconnection  to be effective  beginning on
          the expiration date of this Agreement ("Subsequent Agreement").

        2.3    If, within one hundred and  thirty-five  (135) days of commencing
          the  negotiation  referred  to in Section  2.2 above,  the Parties are
          unable  to   satisfactorily   negotiate   new  resale   and/or   local
          interconnection  terms,   conditions  and  prices,  either  Party  may
          petition the Commission to establish appropriate local interconnection
          and/or  resale  arrangements  pursuant to 47 U.S.C.  151.  The Parties
          agree that,  in such event,  they shall  encourage  the  Commission to
          issue its order regarding the appropriate local interconnection and/or
          resale  arrangements  no  later  than  the  expiration  date  of  this
          Agreement.  The Parties further agree that in the event the Commission
          does not issue its order to the expiration date of this Agreement, oir
          if the Parties  continue  beyond the expiration date of this Agreement
          to negotiate  the local  interconnection  and/or  resale  arrangements
          without  Commission  intervention,  the terms,  conditions  and prices
          ultimately  ordered by the  Commission,  or negotiated by the Parties,
          will be effective retroactive to the day following the expiration date
          of this Agreement.

        2.4    Notwithstanding  the foregoing,  in the event that as of the date
          of expiration of this  Agreement and conversion of this Agreement to a
          month-to-month  term,  the Parties  have not entered into a Subsequent
          Agreement  and  either no  arbitration  proceeding  has been  filed in
          accordance  with  Section 2.3 above , or the Parties have not mutually
          agreed  (where  permissible)  to extend  the  arbitration  window  for
          petitioning the applicable Commission(s) for resolution of those terms
          upon which the Parties have not agreed,then either Party may terminate

          this Agreement upon sixty (60) days notice to the other Party.  In the
          event that  BellSouth  terminates  this  Agreement as provided  above,
          BellSouth shall continue to offer services to Colmena  pursuant to the
          terms,  conditions  and rates set forth in  BellSouth's  Statement  of
          Generally  Available  Terms  (SGAT)  to the  extent  an SGAT  has been
          approved by the applicable Commission(s).  If any state Commission has
          not approved a BellSouth  SGAT, then upon  BellSouth's  termination of
          this Agreement as provided herein,  BellSouth will continue to provide
          services to Colmena  pursuant to  BellSouth's  then  current  standard
          interconnection  agreement.  In the event that the SGAT or BellSouth's
          standard  interconnection  agreement  becomes effective as between the
          Parties, the Parties may continue to negotiate a Subsequent Agreement,
          and the  terms  of  such  Subsequent  Agreements  shall  be  effective
          retroactive to the day following expiration of this Agreement.

3.        Ordering Procedures

        3.1    Colmena shall provide BellSouth its Carrier  Identification  Code
          (CIC),  Operating  Company  Number (OCN),  Group Access Code (GAC) and
          Access  Customer Name and Address  (ACNA) code as applicable  prior to
          placing its first order.

        3.2    The   Parties   agree   to   adhere   to  the   BellSouth   Local
          Interconnection  and Facility Based Ordering Guide and Resale Ordering
          Guide, as appropriate for the services ordered.

        3.3    Colmena shall pay charges for  Operational  Support Systems (OSS)
          as set forth in this Agreement in Attachment 1 and/or in Attachment 2,
          3, 5 and 7 as applicable.

4.        Parity

          telecommunications  services from  BellSouth for the purpose of resale
          to end  users,  BellSouth  shall  provide  said  services  so that the
          services  are equal in quality,  subject to the same  conditions,  and
          provided  within the same  provisioning  time intervals that BellSouth
          provides to its affiliates,  subsidiaries and end users. To the extent
          technically feasible, the quality of a Network Element, as well as the
          quality of the access to such Network Element provided by BellSouth to
          Colmena  shall be at least  equal in quality  to that which  BellSouth
          provides  to itself.  The quality of the  interconnection  between the
          networks of BellSouth  and the network of Colmena  shall be at a level
          that is equal to that which BellSouth  provides  itself, a subsidiary,
          an Affiliate, or any other party. The interconnection facilities shall
          be designed to meet the same technical  criteria and service standards
          that are  used  within  BellSouth's  network  and  shall  extend  to a
          consideration of service quality as perceived by end users and service
          quality as perceived by Colmena.

          deleted listings, on a magnetic tape, computer disk, or other mutually
          agreed upon means.  These procedures are detailed in BellSouth's Local

        5.4    Unlisted/Non-Published  Subscribers.  Colmena will be required to

6.        Bona Fide Request/New Business Request Process for Further Unbundling

          If Colmena is a facilities  based  provider or a facilities  based and
          resale  provider,  this section  shall apply.  BellSouth  shall,  upon
          request of Colmena,  provide to Colmena access to its network elements
          at any  technically  feasible  point for the  provision  of  Colmena's
          telecommunications  service where such access is necessary and failure
          to  provide  access  would  impair  the  ability of Colmena to provide
          services that it seeks to offer.  Any request by Colmena for access to
          a network element,  interconnection option, or for the provisioning of
          any service or product that is not already  available shall be treated
          as a Bona Fide Request/New Business Request, and shall be submitted to
          BellSouth  pursuant  to the Bona Fide  Request./New  Business  Request
          process set forth following.

        6.1    A Bona Fide  Request/New  Business  Request shall be submitted in
          writing to Colmena's Account Manager by Colmena and shall specifically
          identify the requested  service date,  technical  requirements,  space
          requirements  and/or  such  specifications  that  clearly  define  the
          request such that BellSouth has sufficient  information to analyze and
          prepare  a  response.  Such a request  also  shall  include  Colmena's
          designation   of  the   request   as  being   9i)   pursuant   to  the
          Telecommunications  Act of 1966 or (ii)  pursuant  to the needs of the
          business.

7.        Court Ordered Requests for Call Detail Records and Other Subscriber
          Information

          To the extent technically  feasible,  BellSouth  maintains call detail
          records for Colmena end users for limited time periods and can respond
          to  subpoenas  and  court  ordered  requests  for  this   information.
          BellSouth  shall maintain such  information  for Colmena end users for
          the same length of time it maintains such  information for its own end
          users.

        7.1    Colmena agrees that BellSouth will respond to subpoenas and court
          ordered  requests  delivered  directly to BellSouth for the purpose of
          providing  call detail  records  when the targeted  telephone  numbers
          belong  to  Colmena  end  users.  Billing  for such  requests  will be
          generated by  BellSouth  and  directed to the law  enforcement  agency
          initiating the request.

                                    Page 343
<PAGE>

        7.2    Colmena agrees that in cases where Colmena received  subpoenas or
          court ordered requests for call detail records for targeted  telephone
          numbers  belonging  to Colmena end users,  Colmena will advise the law
          enforcement  agency initiating the request to redirect the subpoena or
          court  ordered   request  to   BellSouth.   Billing  for  call  detail
          information  will be generated  by  BellSouth  and directed to the law
          enforcement agency initiating the request.

        7.3    In cases where the timing of the response to the law  enforcement
          agency  prohibits  Colmena from having the  subpoena or court  ordered
          request redirected to BellSouth by the law enforcement agency, Colmena
          will furnish the official  request to BellSouth for providing the call
          detail information.  BellSouth will provide the call detail records to
          Colmena  and bill  Colmena  for the  information,  Colmena  agrees  to
          reimburse BellSouth for the call detail information provided.

        7.4    Colmena  will  provide  Colmena  end user and/or  other  customer
          information  that is available to Colmena in response to subpoenas and
          court orders for their own customer  records.  BellSouth will redirect
          subpoenas and court ordered requests for Colmena end user and/or other
          customer  information  to Colmena  for the purpose of  providing  this
          information to the law enforcement agency.

8.        Liability and Indemnification

        8.1    BellSouth    Liability.    BellSouth    shall   take    financial
          responsibility  for its own actions in causing,  or its lack of action
          in preventing, unbillable or uncollectible Colmena revenues.

        8.2    Colmena Liability.  In the event that Colmena consists of two (2)
          or  more  separate  entities  as set  forth  in the  preamble  to this
          Agreement, all such entities shall be jointly and severally liable for
          the obligations of Colmena under this Agreement.

        8.3    Liability  for  Acts  or  Omissions  of  Third  Parties.  Neither
          BellSouth  nor  Colmena  shall be liable  for any act or  omission  of
          another telecommunications company providing a portion of the services
          provided under this Agreement.

        8.4    Limitation of Liability.

<PAGE>

                8.4.1    Each Party's liability to the other for any loss, cost,
                    claim, injury or liability or expense,  including reasonable
                    attorney's  fees relating to or arising out of any negligent
                    act or omission in its performance of this Agreement whether
                    in contract or in tort, shall be limited to a credit for the
                    actual cost of the  services or functions  not  performed or
                    improperly performed.

                8.4.2    Limitations  in  Tariffs.  A  Party  may,  in its  sole
                    discretion,  provide in its tariffs and  contracts  with its
                    Customer  and third  parties  that  relate  to any  service,
                    product or  function  provided  or  contemplated  under this
                    Agreement,   that  to  the  maximum   extent   permitted  by
                    Applicable  Law,  such Party shall not be liable to Customer
                    or third  Party for (i) any Loss  relating to or arising out
                    of this Agreement,  whether in contract,  tort or otherwise,
                    that  exceeds the amount such Party would have  charged that
                    applicable person for the service,  product or function that
                    gave rise to such Loss and (ii)  Consequential  Damages.  To
                    the extent  that a Party  elects not to place its tariffs or
                    contracts such limitations of liability, and the other Party
                    incurs  a  Loss  as  a  result  thereof,  such  Party  shall
                    indemnify  and reimburse the other Party for that portion of
                    the Loss that would have been  limited  had the first  Party
                    included in its tariffs and  contracts  the  limitations  of
                    liability  that such other Party included in its own tariffs
                    at the time of such Loss.

                8.4.3    Neither  BellSouth  nor  Colmnena  shall be liable  for

Mississippi, North Carolina, South Carolina, and Tennessee.

     Daily  Usage File is the  compilation  of messages or copies of messages in
standard  Exchange Message  Interface (EMI) format exchanged from BellSouth to a
CLEC.

for  the   exchange   of  data   among  the   Exchange   Carriers   within   the
telecommunications industry.

provider  or  information  service  provider.  As further  clarification,  Local
Traffic does not include  calls that do not transmit  information  of the user's

          service will be used in violation of the law.

          intended solely for the use of the end user of the feature.  Resale of
          this information is prohibited.

5.       Maintenance of Services

        5.1    Colmena will adopt and adhere to the  standards  contained in the
          applicable  CLEC  Work  Center  Operational   Understanding  Agreement
          regarding maintenance and installation of service.

        5.2    Services  resold under  BellSouth's  Tariffs and  facilities  and
          equipment provided by BellSouth shall be maintained by BellSouth.

        5.3    Colmena  or its end users may not  rearrange,  move,  disconnect,
          remove or attempt to repair any facilities  owned by BellSouth,  other
          than by  connection  or  disconnection  to any  interface  means used,
          except with the written consent of BellSouth.

<PAGE>

        5.4    Colmena accepts  responsibility to notify BellSouth of situations
          that arise that may result in a service problem.

        5.5    Colmena  will be  BellSouth's  single  point of  contact  for all
          repair calls on behalf of Colmena's  end users.  The parties  agree to
          provide one another with toll-free contact numbers for such purposes.

        5.6    Colmena will contact the appropriate repair centers in accordance
          with procedures established by BellSouth.

        5.7    For all  repair  requests,  Colmena  accepts  responsibility  for
          adhering to BellSouth's prescreening guidelines prior to referring the
          trouble to BellSouth.

        5.8    BellSouth will bill Colmena for handling  troubles that are found
          not to be in  BellSouth's  network  pursuant to its standard  time and
          material  charges.  The standard time and material  charges will be no
          more than what BellSouth  charges to its retail customers for the same
          service.

        5.9    BellSouth  reserves the right to contact  Colmena's end users, if
          deemed necessary, for maintenance purposes.

6.       Establishment of Service

        6.1    After receiving  certification  as a local exchange  company from
          the   appropriate   regulatory   agency,   Colmena  will  provide  the
          appropriate  BellSouth  service center the necessary  documentation to
          enable  BellSouth to establish a master  account for Colmena's  resold
          services.  Such documentation shall include the Application for Master
          Account, proof of authority to provide telecommunications services, an
          Operating  Company  Number ("OCN")  assigned by the National  Exchange
          Carriers  Association  ("NECA") and a tax  exemption  certificate,  if
          applicable.  When necessary  deposit  requirements are met,  BellSouth
          will begin taking orders for the resale of service.

        6.2    Service  orders  will  be  in a  standard  format  designated  by
          BellSouth.

        6.3    When  notification  is received  from  Colmena that a current end
          user of  BellSouth  will  subscribe  to  Colmena's  service,  standard
          service  order  intervals  for the  appropriate  class of service will
          apply.

        6.4    BellSouth  will  not  require  end  user  confirmation  prior  to
          establishing  service for Colmena's end user  customer.  Colmena must,
          however, be able to demonstrate end user authorization upon request.

                               Attachment 1 - Page 367
<PAGE>

        6.5    Colmena will be the single point of contact  with  BelLSouth  for
          all subsequent  ordering activity resulting in additions or changes to
          resold services  except that BellSouth will accept a request  directly
          from  the end user  for  conversion  of the end  user's  service  from
          Colmena to  BellSouth  or will accept a request  from another CLEC for
          conversion  of the end user's  service  from Colmena to the other LEC.
          BellSouth will notify Colmena that such a request has been processed.

        6.6    If  BellSouth  determines  that an  unauthorized  change in local
          service to Colmena has occurred,  BellSouth will  reestablish  service
          with the appropriate local service provider and will assess Colmena as
          the CLEC initiating the unauthorized  change, the unauthorized  change
          charge  described  in F.C.C.  Tariff No. 1,  Section 13 or  applicable
          state  tariff.  Appropriate  nonrecurring  charges,  as set  forth  in
          Section A4 of the  General  Subscriber  Service  Tariff,  will also be
          assessed to Colmena. These charges can be adjusted if Colmena provides
          satisfactory proof of authorization.

        6.7    In order to safeguard its interest,  BellSouth reserves the right
          to secure the account with a suitable form of security deposit, unless
          satisfactory credit has already been established.

                6.7.1    Such  security  deposit  shall  take  the  form  of  an
                    irrevocable  Letter  of Credit  or other  forms of  security
                    acceptable  to BellSouth.  Any such security  deposit may be
                    held during the  continuance  of the service as security for
                    the payment of any and all amounts accuring for the service.

                6.7.2    If  a  security  deposit  is  required,  such  security
                    deposit shall be made prior to the inauguration of service.

                6.7.3    Such  security  deposit  may  not  exceed  two  months'
                    estimated billing.

                6.7.4    The fact that a  security  deposit  has been made in no
                    way  relieves   Colmena  from  complying  with   BellSouth's
                    regulations as to advance payments and the prompt payment of
                    bills on  presentation  nor does it  constitute  a waiver or
                    modification of the regular practices of BellSouth providing
                    for the  discontinuance  of service for  non-payment  of any
                    sums due BellSouth.

                6.7.5    BellSouth  reserves  the right to increase the security
                    deposit   requirements   when,   in  its   sole   judgement,
                    circumstances  so warrant  and/or gross monthly  billing has
                    increased  beyond the level  initially used to determine the
                    security deposit.

                6.7.6    In the event  that  Colmena  defaults  on its  account,
                    service  to  Colmena  will be  terminated  and any  security
                    deposits held will be applied to its account.

                6.7.7    Interest on a security deposit shall accrue and be paid
                    in accordance  with the terms in the  appropriate  BellSouth
                    tariff.

7.       Payment And Billing Arrangements

        7.1    Prior to  submitting  orders to BellSouth  for local  service,  a
          master account must be established for Colmena. Colmena is required to
          provide the following before a master account is established: proof of
          PSC/PUC   certification,   the  Application  for  Master  Account,  an
          Operating  Company  Number ("OCN")  assigned by the National  Exchange
          Carriers  Association  ("NECA") and a tax  exemption  certificate,  if
          applicable.

        7.2    BellSouth  shall bill Colmena on a current  basis all  applicable
          charges and credits.

        7.3    Payment of all  charges  will be the  responsibility  of Colmena.
          Colmena  shall make  payment to  BellSouth  for all  services  billed.
          BellSouth is not responsible for payments not received by Colmena from
          Colmena's  end user.  BellSouth  will not become  involved  in billing
          disputes  that may arise  between  Colmena and its end user.  Payments
          made to  BellSouth  as  payment  on  account  will be  credited  to an
          accounts receivable master account and not to an end user's account.

        7.4    BellSouth will render bills each month on  established  bull days
          for each of Colmena's accounts.

        7.5    BellSouth  will bill Colmena in advance  changes for all services
          to be  provided  during the  ensuing  billing  period  except  charges
          associated  with  service  usage,  which  will be billed  in  arrears.
          Charges will be calculated on an  individual  end user account  level,
          including,  if applicable,  any charge for usage or usage  allowances.
          BellSouth will also bill Colmena,  and Colmena will be responsible for
          and remit to  BellSouth,  all charges  applicable  to resold  services
          including but not limited to 911 and E911 charges,  telecommunications
          relay charges (TRS), and franchise fees.

        7.6    The payment will be due by the next bill date (i.e., same date in
          the  following  month as the bill date) and is payable in  immediately
          available funds. Payment is considered to have been made when received
          by BellSouth.

                7.6.1    If the  payment  due date  falls  on a  Sunday  or on a
                    Holiday which is observed on a Monday,  the payment due date
                    shall be the first  non-Holiday day following such Sunday or
                    Holiday. If the payment due date falls on a Saturday or on a
                    Holiday which is observed on Tuesday,  Wednesday,  Thursday,
                    or  Friday,   the   payment  due  date  shall  be  the  last
                    non-Holiday  day  preceding  such  Saturday or  Holiday.  If
                    payment is not  received  by the  payment  due date,  a late
                    payment  penalty,  as set forth in  section  7.8  following,
                    shall apply.

                7.6.2    If  Colmena   requests   multiple   billing   media  or
                    additional copies of bills,  BellSouth will provide these at
                    an appropriate charge to Colmena.

                7.6.3    Billing Disputes

                                  Attachment 1 - Page 369
<PAGE>

                7.6.3.1  Each Party  agrees to notify  the other  Party upon the
                    discovery  of a billing  dispute.  In the event of a billing
                    dispute,  the Parties  will  endeavor to resolve the dispute
                    within  sixty (60)  calendar  days of the Bill Date on whcih
                    such disputed  charges appear.  Resolution of the dispute is
                    expected to occur at the first level of management resulting
                    in a  recommendation  for  settlement  of  the  dispute  and
                    closure of a specific billing period.  If the issues are not
                    resolved  within the  allotted  time  frame,  the  following
                    resolution procedure will begin:

                7.6.3.2  If the dispute is not resolved within sxty (60) days of
                    the Bill Date,  the dispute  will be escalated to the second
                    level of management for each of the  respective  Parties for
                    resolution. If the dispute is not resolved within ninety (9)
                    days of the Bill Date,  the dispute will be escalated to the
                    third level of management for each of the respective Parties
                    for resolution.

                7.6.3.3  If the dispute is not  resolved  within one hundred and
                    twenty  (120) days of the Bill  Date,  the  dispute  will be
                    escalated to the fourth level of management  for each of the
                    respective Parties for resolution.

                7.6.3.4  If a Party  disputes  a  charge  and  does not pay such
                    charge  by the  payment  due  date,  such  charges  shall be
                    subject  to late  payment  charges  as set forth in the Late
                    Payment  Charges  provision of this  Attachment.  If a Party
                    disputes  charges  and the  dispute is  resolved in favor of
                    such Party,  the other  Party  shall  credit the bill of the
                    disputing Party for the amount of the disputed charges along
                    with any late  payment  charges  assessed  no later than the
                    second  Bill  Date  after  the  resolution  of the  dispute.
                    Accordingly,  if a Party disputes charges and the dispute is
                    resolved in favor of the other Party,  the  disputing  Party
                    shall pay the other Party the amount of the disputed charges
                    and any associated  late payment  charges  assessed no later
                    than the second bill  payment due date after the  resolution
                    of the dispute. BellSouth shall only assess payment due date
                    after the  resolution of the dispute.  BellSouth  shall only
                    assess interest on previously  assessed late payment charges
                    in a state where it has authority pursuant to its tariffs.

        7.7    Upon proof of tax exempt  certification  from Colmena,  the total
          amount  billed to Colmena  will not include any taxes due from the end
          user to  reflect  the tax  exempt  certification  and  local tax laws.
          Colmena  will be solely  responsible  for the  computation,  tracking,
          reporting, and payment of taxes applicable to Colmena's end user.

        7.8    If any portion of the payment is received by BellSouth  after the
          payment  due date as set forth  preceding,  or if any  portion  of the
          payment is received  by  BellSouth  in funds that are not  immediately
          available to  BellSouth,  then a late payment  penalty shall be due to
          BellSouth.  The  late  payment  penalty  shall be the  portion  of the
          payment  not  received by the payment due date times a late factor and
          will be applied on a per bill basis.  The late factor  shall be as set
          forth in  Section A2 of the  General  Subscriber  Services  Tariff and
          Section B2 of the Private Line Service Tariff. Colmena will be charged
          a fee for all  returned  checks as set forth in  Section  to A2 of the
          General Subscriber Services Tariff or in applicable state law.

                                  Attachment 1 - Page 370
<PAGE>

        7.9    Any switched access charges associated with interexchange carrier
          access to the resold local  exchange  lines will be billed by, and due
          to, BellSouth. No additional charges are to be assessed to Colmena.

        7.10   BellSouth will not perform  billing and  collection  services for
          Colmena as a result of the execution of this  Agreement.  All requests
          for billing  services should be referred to the appropriate  entity or
          operational group within BellSouth.

        7.11   Pursuant to 47 CFR Section  51.617,  BellSouth  will bill Colmena
          end user common line  charges  identical  to the end user common lines
          charges BellSouth bills its end users.

        7.12   In  general,  BellSouth  will not  become  involved  in  disputes
          between Colmena and Colmena's end user customers over resold services.
          If a dispute does arise that cannot be settled without the involvement
          of BellSouth,  Colmena shall contact the designated Service Center for
          resolution.  BellSouth  will  make  every  effort  to  assist  in  the
          resolution  of the  dispute  and will wok with  Colmena to resolve the
          matter in as timely a manner as  possible.  Colmena may be required to
          submit documentation to substantiate the claim.

8.       Discontinuance of Service

        8.1    The  procedures for  discontinuing  service to an end user are as
          follows:

                8.1.1    Where   possible,   BellSouth   will  deny  service  to
                    Colmena's  end user on behalf  of,  and at the  request  of,
                    Colmena.   Upon  restoration  of  the  end  user's  service,
                    restoral  charges will apply and will be the  responsibility
                    of Colmena.

                8.1.2    At the request of Colmena,  BellSouth will disconnect a
                    Colmena end user customer.

                8.1.3    All requests by Colmena for denial or  disconnection of
                    an end user for nonpayment must be in writing.

                8.1.4    Colmena will be made solely  responsible  for notifying
                    the end user of the proposed disconnection of the service.

                8.1.5    BellSouth  will  continue to process  calls made to the
                    Annoyance  Call  Center and will advise  Colmena  when it is
                    determined  that annoyance  calls are originated from one of
                    their end user's locations.  BellSouth shall be indemnified,
                    defended  and held  harmless by Colmena  and/or the end user
                    against any claim,  loss or damage  arising  from  providing
                    this  information to Colmena.  It is the  responsibility  of
                    Colmena to take the corrective action necessary with its end
                    users who make annoying calls.  Failure to do so will result
                    returned checks as set forth in Section to A2 of the General
                    Subscriber  Services  Tariff  or  in  applicable  state  law
                    in BellSouth's disconnecting the end user's service.

                               Attachment 1 - Page 371
<PAGE>

                8.1.6    BellSouth may disconnect and reuse  facilities when the
                    facility is in a denied state and  BellSouth has received an
                    order to  establish  new service or transfer of service from
                    an end user or an end user's CLEC at the same address served
                    by the denied facility.

        8.2    The  procedures  for  discontinuing  service  to  Colmena  are as
          follows:

                8.2.1    BellSouth  reserves  the right to suspend or  terminate
                    service  for  nonpayment  or in  the  event  of  prohibited,
                    unlawful or improper use of the facilities or service, abuse
                    of the facilities,  or any other violation or  noncompliance
                    by  Colmena  of the  rues  and  regulations  of  BellSouth's
                    Tariffs.

                8.2.2    If payment of account is not  received  by the bill day
                    in the month  after the  original  bill day.  BellSouth  may
                    provide   written   notice  to  Colmena,   that   additional
                    applications  for  service  will be  refused  and  that  any
                    pending  orders for service will not be completed if payment
                    is not received by the  fifteenth  day following the date of

                    to receive  notices of  noncompliance,  and  discontinue the

                                    Exhibit A

                    OPERATIONAL SUPPORT SYSTEMS (OSS) RATES

     BellSouth has developed and made available the following mechanized systems
by which Colmena may submit LSRs electronically.

         LENS                   Local Exchange Navigation System
         EDI                    Electronic Data Interface
         EDI-PC                 Electronic Date Interface - Personal Computer
         TAG                    Telecommunications Access Gateway

     LSRs submitted by means of one of these  interactive  interfaces will incur
an OSS  electronic  ordering  charges  as  specified  in  the  Table  below.  An
individual  LSR will be identified  for billing  purposes by its Purchase  Order
Number  (PON).  LSRs  submitted  by means  other  than one of these  interactive
interfaces  (mail,  fax,  couries,  etc.)  Will incur a manual  order  charge as
specified in the table below.

OPERATIONAL        Electronic                        Manual
SUPPORT            Per LSR received from the        Per LSR received from the
SYSTEMS (OSS)      CLEC by one of the OSS           CLEC by means other than one
RATES              Interactive interfaces           of the OSS interactive
                                                    Interfaces

OSS LSR Charge     $3.50                            $19.99
USOC               SOMEC                            SOMAN

     Note: In addition to the OSS charges,  applicable  discounted service order
and related discounted charges apply per the tariff.

     Denial/Restoral OSS Charge

     In the  event  Colmena  provides  a list  of  customers  to be  denied  and
restored,  rather than an LSR, each location on the list will require a separate
PON and, therefore, will be billed as one LSR per location.

     Cancellation OSS Charge

     Colmena will incur an ODD charge for an accepted LSR that is later canceled
by Colmena.

     Note:  Supplements or  clarifications  to a previously  billed LSR will not
incur another OSS charge.

     Threshold Billing Plan

     The Parties  agree that  Colmena will incur the  mechanized  rate for LSRs,
both manual, if the percentage of mechanized LSRs meets or exceeds the threshold
percentages shown below:

         Year                       Ratio: Mechanized/Total LSRs
         1999                                        70%
         2000                                        80%
         2001                                        90%

     The threshold plan will be discontinued in 2002.

     BellSouth  will track the total LSR volume for each CLEC for each  quarter.
At the end of that time period,  a Percent  Electronic LSR  calculation  will be
made  for  that  quarter  based on the LSR data  tracked  in the  LCSC.  If this
percentage  exceeds the threshold volume,  all of that CLECs' future manual LSRs
will be billed at the  mechanized  LSR rate.  To allow  time for  obtaining  and
analyzing  the data and updating the billing  system,  this billing  change will
take place on the first day of the second month following the end of the quarter
(e.g.  May 1 for 1Q, Aug. 1 for 2Q, etc.).  There will be no  adjustments to the
amount billed for previously billed LSRs.

          included  in the LIDB  query.  BellSouth  will  establish  fraud alert
          thresholds and will notify Colmena of fraud alerts so that Colmena may
          take  action it deems  appropriate.  Colmena  understands  and  agrees
          BellSouth will  administer all data stored in the LIDB,  including the
          data  provided  by Colmena  pursuant  to this  Agreement,  in the same
          manner  as  BellSouth's  data  for  BellSouth's  end  user  customers.
          BellSouth  shall not be  responsible  to Colmena for any lost  revenue
          which may result from BellSouth's  administration of the LIDB pursuant
          to its  established  practices and procedures as the exist and as they
          may be changed by BellSouth in its sole discretion from time to time.

         Colmena  understands  that BellSouth  currently hsa in effect  numerous
         billing and collection agreements with various  interexchange  carriers
         and billing  clearing  houses.  Colmena further  understands that these
         billing and collection customers of BellSouth query BellSouth's LIDB to
         determine  whether to accept  various  billing  options from end users.
         Additionally,  Colmena  understands  that  presently  BellSouth  has no
         method to differentiate  between  BellSouth's own billing and line data
         in the LIDB and such data which it  includes  in the LIDB on  Colmena's
         behalf  pursuant  to this  Agreement.  Therefore,  until  such  time as
         BellSouth can and does implement in its LIDB and its supporting systems
         the means to differentiate Colmena's data from BellSouth's data and the
         Parties to this Agreement execute  appropriate  amendments  hereto, the
         following terms and conditions shall apply.

         collection customers for Colmena's end user accounts which are resident
         in LIDB pursuant top this Agreement.  Colmena  authorizes  BellSouth to

         page  identified  with the name of the  entity for which  BellSouth  is
         billing the charge.

   (3)   Colmena shall have the  responsibility to render a billing statement to
         its end  users for  these  charges,  but  Colmena's  obligation  to pay
         BellSouth  for the  charges  billed  shall be  independent  of  whether
         Colmena is able or not to collect from Colmena's end users.

   (4)   BellSouth  shall not become involved in any dispute between Colmena and
         the  entities  for which  BellSouth  performs  billing and  collection.
         BellSouth will not issue adjustments for charges billed on behalf of an
         entity to Colmena.  It shall be the  responsibility  of Colmena and the

          provision  of the  service  set forth  herein will be paid by Colmena.
          Colmena  shall  have the  right  to have  BellSouth  contest  with the

         other Party is responsible under this Section and to cooperate in every
         reasonable  way to  facilitate  defense or  settlement  of claims.  The
         indemnifying   Party  shall  not  be  liable  under  this  Section  for
         settlement by the indemnifying Party of any claim,  lawsuit,  or demand
         unless the defense of the claim,  lawsuit,  or demand has been tendered

          will request any toll billing exceptions via the Local Service Request
          (LSR) form used to order  resold  exchange  lines,  or the SPP service
          request form used to order SPNP arrangements.

        B.     Under normal  operating  conditions,  BellSouth shall include the
          billing number  information in its LIDB upon completion of the service
          order  establishing  either the resold local  exchange  service or the
          SPNP   arrangement,   provided  that  BellSouth   shall  not  be  held
          responsible for any delay or failure in performance to the extent such
          delay or  failure  is caused by  circumstances  or  conditions  beyond
          BellSouth's  reasonable  control.  BellSouth will store in its LIDB an
          unlimited  volume of the working  telephone  numbers  associated  with

          separate agreement is required.

        C.     BellSouth will provide responses to on-line, call-by-call queries
          to the stored information for the specific purposes listed in the next
          paragraph.

          perform the  following  functions for  authorized  users on an on-line
          basis:

        1.     Validate a 14 digit Calling Card number where the first 10 digits
          are a line number or special billing number assigned by BellSouth, and
          where the last four  digits  (PIN) are a  security  code  assigned  by
          BellSouth.

        2.     Determine  whether the Colmena has  identified the billing number
          as one which should not be billed for collect or third  number  calls,
          or both.

          Parties with consideration  given to time necessary for the completion
          of required Telcordia  (formerly BellCore)  functions.  BellSouth will
          request the assignment of an RAO code from its connecting  contractor,
          currently Telcordia (formerly BellCore), on behalf of Colmena and will
          coordinate all associated conversion activities.

5.        BellSouth will receive  messages from Colmena that are to be processed
          by  BellSouth,  another LEC or CLEC in the  BellSouth  region or a LEC
          outside the BellSouth region.

6.       BellSouth will perform invoice sequence  checking,  standard EMI format
         editing,  and  balancing  of message  data with the EMI trailer  record
         counts on all data received from Colmena.

7.       All data  received  from  Colmena  that is to be processed or billed by
         another LEC or CLEC within the BellSouth  region will be distributed to
         that LEC or CLEC in accordance  with the  agreement(s)  which may be in
         effect between BellSouth and the involved LEC or CLEC.

8.       All data received from Colmena that is to be placed on the CMDS network
         for  distribution  outside  the  BellSouth  region  will be  handled in
         accordance  with  the  agreement(s)  which  may  be in  effect  between
         BellSouth and its connecting  contractor (currently Telcordia (formerly
         BellCore)).

                                  Attachment 1 - Page 384
                                   EXHIBIT D
<PAGE>

9.       BellSouth will receive messages from the CMDS network that are destined
         to be  processed by Colmena and will forward them to Colmena on a daily
         basis.

10.      Transmission of message data between BellSouth and Colmena will be via
         CONNECT: Direct.

11.      All messages and related data exchanged  between  BellSouth and Colmena
         will be formatted in accordance  with accepted  industry  standards for
         EMI formatted  records and packed  between  appropriate  EMI header and
         trailer records, also in accordance with accepted industry standards.

12.      Colmena  will ensure that the  recorded  message  detail  necessary  to
         recreate  files  provided to BellSouth  will be maintained  for back-up
         purposes for a period of three (3) calendar  months  beyond the related
         message dates.

13.      Should  it become  necessary for Colmena to send data to BellSouth more
         than  sicty (60) days past the  message  date(s),  Colmena  will notify
         BellSouth in  advance of the transmission of the data. If there will be
         impacts  outside  the BellSouth  region,  BellSouth  will work with its
         connecting contractor and Colmena to notify all affected Parties.

14.      In  the event that data to be exchanged  between the two Parties should
         become  lost or destroyed, both Parties will work together to determine
         the  source of  the  problem.  Once the cause of the  problem  has been
         jointly  determined  and the responsible  Party  (BellSouth or Colmena)
         identified  and agreed to, the  company  responsible  for  creating the
         data  (BellSouth  or  Colmena)  will  make  every  effort  to have  the
         affected  data  restored   and  retransmitted.  If the data  cannot  be
         retrieved,  the responsible Party will be liable to the other Party for
         any  resulting  lost  revenue.  Lost revenue  may be a  combination  of
         revenues  that could be billed to the end users and  associated  access
         revenues.  Both  Parties  will  work  together to estimate  the revenue
         amount based  upon  historical  data through a method  mutually  agreed
         upon.  The  resulting  estimated  revenue  loss  will  be  paid by the
         responsible  Party to the other Party within  three (3) calendar months
         of the date of  problem  resolution,  or as mutually agreed upon by the
         Parties.

15.      Should  an error be  detected  by the EMI  format  edits  performed  by
         BellSouth on data received from Colmena, the entire pack containing the
         affected data will not be processed by BellSouth. BellSouth will notify
         Colmena of the error  condition.  Colmena will correct the error(s) and
         will resend the entire pack to BellSouth for  processing.  In the event
         that an out-of-sequence  condition occurs on subsequent packs,  Colmena
         will resend these pack to BellSouth after the pack containing the error
         has been successfully reprocessed by BellSouth.

17.      In  no case shall either Party be liable to the other for any direct or
         consequential  damages incurred  as a result of the obligations set out
         in this agreement.

          the  circuit,   overseeing  its   installation  and  coordinating  the
          installation with BellSouth.  Colmena will also be responsible for any
          charges associated with this line. Equipment required on the BellSouth
          end to  attach  the line to the  mainframe  computer  and to  transmit
          successfully ongoing will be negotiated on a case by case basis. Where
          a dial-up facility is required, dial circuits will be installed in the
          BellSouth data center by BellSouth and the associated charges assessed
          to Colmena. Additionally, all message toll charges associated with the
          use of the dial  circuit  by  Colmena  will be the  responsibility  of
          Colmena. Associated equipment on the BellSouth end, including a modem,
          will be negotiated on a case by case basis between the Parties.

        18.4   All equipment,  including modems and software, that is requird on
          the  Colmena  end for the  purpose  of data  transmission  will be the
          responsibility of Colmena.

19.      Intercompany Settlements Messages

        19.1   This Section addresses the settlement of revenues associated with
          traffic  originated  from or billed by Colmena as a  facilities  based
          provider of local exchange  telecommunications  aservices  outside the
          BellSouth  region.  Only traffic that originates in one Bell operating
          territory and bills in another Bell  operating  territory is included.
          Traffic  that  originates  and bills  within  the same Bell  operating
          territory  will be settled on a local  basis  between  Colmena and the
          involved company(ies), unless that company is participating in NICS.

        19.2   Both  traffic that  originates  outside the  BellSouth  region by
          Comena and is billed  within the  BellSouth  region,  and traffic that
          originates  within  the  BellSouth  region and is billed  outside  the
          BellSouth region by Colmena, is covered by this Agreement (CATS). Also
          covered is traffic that either is  originated by or billed by Colmena,
          involves a company other than Colmena,  qualifies for inclusion in the
          CATS settlement,  and is not originated or billed within the BellSouth
          region (NICS)

       .

        19.3   Once  Colmena  is  operating  within  the  BellSouth   territory,
          revenues  associated  with  calls  originated  and  billed  within the
          BellSouth region will be settled via Telcordai (formerly  BellCore)'s,
          its successor or assign, NICS system.

        19.4   BellSouth  will receive the monthly  NICS reports from  Telcordia
          (formerly  BellCore),  its successor or assign,  on behalf of Colmena.
          BellSouth  will  distribute  copies of these  reports  to Colmena on a
          monthly basis.

        19.5   BellSouth will receive the monthly  Calling Card and Third Number
          Settlement System (CATS) reports from Telcordia  (formerly  BellCore),
          its  successor  or  assign,  on  behalf  of  Colmena.  BellSouth  will
          distribute copies of these reports to Colmena.

        19.6   BellSouth  will  collect the revenue  earned by Colmena  from the
          Bell  operating  company in whoce  territory  the  messages are billed
          (CATS),  less a per message  billing and  collection fee of five cents
          ($0.05), on behalf of Colmena. BellSouth will remit the revenue billed
          by  Colmena  to the Bell  operating  company  in whose  territory  the
          messages originated,  less a per message billing and collection fee of
          five cents  ($0.05),  on behalf on Colmena.  These two amounts will be
          netted together by BellSouth and the resulting charge or credit issued
          to  Colmena  via  a  monthly  Carrier  Access  Billing  System  (CABS)
          miscellaneous bill.

        19.7   BellSouth  will collect the revenue  earned by Colmena within the
          BellSouth  territory  from  another  CLEC also  within  the  BellSouth
          territory  (NICS) where the  messages  are billed,  less a per message
          billing and  collection  fee of five  centee\s  ($0.05),  on behalf of
          Colmena. BellSouth will remit the revenue billed by Colmena within the
          BellSouth region to the CLEC also within the BellSouth  region,  where
          the messages originated, less a per message billing and collection fee
          of five cents  ($0.05).  These two amounts will be netted  together by
          BellSouth and the  resulting  charge or credit issued to Colmena via a
          monthly  Carrier  Access  Billing  System (CABS)  miscellaneous  bill.
          BellSouth and Colmena agree that monthly  netted  amounts of less than
          fifty dollars ($50.00) will not be settled.

          packs  (via the  mutually  agreed  medium).  Packs  could be  rejected
          because of pack sequencing discrepancies or a critical edit failure on
          the Pack Header or Pack Trailer records (i.e. out-of-balance condition
          on grand  totals,  invalid data  populated).  Standard  ATIS EMI Error
          Codes will be used.  Colmena will not be required to return the actual
          rejected  data to  BellSouth.  Rejected  packs will be  corrected  and
          retransmitted to Colmena by BellSouth.

6.5      Control Data

         Colmena  will send one  confirmation  record per pack that is  received
         from BellSouth. This confirmation record will indicate Colmena received
         the pack and the  acceptance  or  rejection  of the pack.  Pack  status
         Code(s) will be populated using standard ATIS EMI error codes for packs
         that were rejected by Colmena for reasons stated in the above section.

                  CALLING NAME DELIVERY (CNAM) DATABASE SERVICES

1.       DEFINITIONS

         For the  purpose  of this  Attachment,  the  following  terms  shall be
defined as:

         CALLING NAME DELIVERY DATABASE SERVICE (CNAM) - The ability

         to  associate a name with the calling  party  number,  allowing the end
         user  subscriber  (to  which a call is  being  terminated)  to view the
         calling  party's  name before the call is  answered.  This service also
         provides Colmena the opportunity to load and store its subscriber names
         in the BellSouth CNAM SCPs.

         CALLING  PARTY NUMBER  (CPN) - Thenumber  of the calling  party that is
         delivered to the  terminating  switch using  common  channel  sugnaling
         system  7  (CCS7)  technology,  and that is  contained  in the  Initial
         Address Message (IAM) portion of the CCS7 call steup.

         COMMON CHANNEL SIGNALING SYSTEM 7 (CCS&) - A network
         signaling technology in which all signaling  information between two of
         more nodes is transmitted over high-speed data links,  rather than over
         voice circuits.

         SERVICE  CONTROL  POINTs (SCPs) - The real-time  data base systems that
         contain the names to be provided in response to queries  received  form
         CNAM SSPs.

         SERVICE MANAGEMENT SYSTEM (SMS) - The main operations support system of
         CNAM DATABASE  SERVICE.  CNAM records are loaded into the SMS, which in
         turn downloads into the CNAM SCP.

         SERVICE SWITCHING POINTs (SSPs) - Features of computerized  switches in
         the  telephone  network  that  determine  that a  terminating  line has
         subscriber  to CNAM  service,  and then  communicate  with CNAM SCPs in
         order to provide the name associated with the calling party number.

         SUBSYSTEM  NUMBER (SSN) - The address used in the Signaling  Connection
         Control  Part  (SCCP)  layer  of  the  SS7  protocol  to  designate  an
         application at an end signaling point. A SSN for CNAM at the end office
         designates the CNAM application  within the end office.  BellSouth uses
         the CNAM SSN of 232.

2.       ATTACHMENT

        2.1    This Attachment contains the terms and conditions where BellSouth
          will provide to Colmena  access to the BellSouth CNAM SCP for query or

3.       PHYSICAL CONNECTION AND COMPENSATION

        3.1    BellSouth's  provision  of  CNAM  Database  Services  to  Colmena
          requires  interconnection  from  Colmena  to  BellSouth  CNAM  Service
          Control  Points  (SCPs).  Such  interconnections  shall be established
          pursuant to Attachment 3 of this Agreement. The appropriate charge for
          access to and use of the BellSouth  CNAM Database  service shall be as
          set forth in this Attachment.

        3.2    In order to  formulate  a CNAM query to be sent to the  BellSouth
          CNAM SCP, Colmena shall provide its own CNAM SSP.  Colmena's CNAM SSPs
          must be compliant  with  TR-NWT-001188,  "CLASS  Calling Name Delivery
          Generic Requirements."

        3.3    If Colmena  elects to access the  BellSouth  CNAM SCP via a third
          party CCS7  transport  provider,  the third party CCS7 provider  shall
          interconnect with the BellSouth CCS7 network according the BellSouth's
          Common  Channel  Signaling  Interconnection  Guidelines  and Telcordia
          (formerly  BellCore)'s CCS Network Interface  Specification  document,
          TR-TSV-000905.  In addition,  the third party provider shall establish
          CCS7  interconnection  at the BellSouth  Local Signal  Transfer Points
          (LSTPs) serving the BellSouth CNAM SCPs that Colmena desires to query.

        3.4    Out-Of-Region  Customers.  If the customer  queries the BellSouth
          CNAM SCP via a third party national SS7 transport provider,  the third
          party SS7 provider shall  interconnect with the BellSouth CCS7 network
          according to  BellSouth's  Common  Channel  Signaling  Interconnection
          Guidelines  and  Bellcore's   CCS  Network   Interface   Specification
          document, TR-TSV-000905. In additional, the third party provider shall
          establish SS7  interconnection at one or more of the BellSouth Gateway
          Signal  Transfer  Points (STPs).  The payment of all costs  associated
          with  the  transport  of  SS7  signals  via  a  third  party  will  be
          established by mutual  agreement of the parties and writing shall,  by
          this reference become an integral part of this Agreement

4.       CNAM RECORD INITIAL LOAD AND UPDATES

        4.1    The  mechanism to be used by Colmena for initial CNAM record load
          and/or  updates shall be determined by mutual  agreement.  The initial
          load and all updates  shall be  provided  by Colmena in the  BellSouth
          specified format and shall contain records for every working telephone
          number that can originate  phone calls.  It is the  responsibility  of
          Colmena to provide  accurate  information  to  BellSouth  on a current
          basis.

        4.2    Updates to the SMS shall occur no less than once a week,  reflect
          service order activity  affecting either name or telephone number, and
          involve only record additions, deletions or changes.

        4.3    Colmena CNAM records  provided for storage in the BellSouth  CNAM
          SCP shall be  available,  on a SCP query  basis  only,  to all parties
          querying  the  BellSouth  CNAM SCP.  Further,  CNAM  service  shall be
          provided  by  each  party   consistent   with  state  and/or   federal
          regulation.
