RE:  TELECONFERENCE RECORDING AND REPLAY SERVICE

Dear Maggie:

I apologize for the delay in responding to your Nov. 20 memo in which you
provided me with a draft of the agreement by which Interactive Telesis will
provide recording and playback services to AT&T.

I provided a draft copy of Exhibit B (pricing schedule) to Rob Mayer and have
just received his approval. Attached is the Exhibit B pricing schedule for
inclusion in the agreement. I have not yet received a draft of Exhibit A (the
description of services to be provided) from you and look forward to receiving
same at your earliest convenience.

We commenced providing services approximately Nov. 15, and will be invoicing
AT&T the first week in January for service provided in November and December.
As such, it would be best for all concerned if we could expedite the
finalization and execution of this agreement.

I do not have any comments or revisions on the form of draft agreement that you
forwarded to me so that once the exhibits are finalized we should be in a
position to execute the agreement.

I look forward to hearing from you shortly.

Yours very truly,

/s/ DONALD E. CAMERON

If a dispute arises out of or relates to this Agreement, or its breach, and the
parties have not been successful in resolving such dispute through negotiation,
the parties agree to attempt to resolve the dispute through mediation by
submitting the dispute to a sole mediator selected by the parties or, at any
time at the option of a party, to mediation by the American Arbitration
Association ("AAA"). Each party shall bear its own expenses and an equal share
of the expenses of the mediator and the fees of the AAA. The parties, their
representatives, other participants and the mediator shall hold the existence,
content and result of the mediation in confidence. If such dispute is not
resolved by such mediation, the parties shall have the right to resort to any
remedies permitted by law. All defenses based on passage of time shall be
tolled pending the termination of the mediation. Nothing in this clause shall
be construed to preclude any party from seeking injunctive relief in order to
protect its rights pending mediation. A request by a party to a court for such
injunctive relief shall not be deemed a waiver of the obligation to mediate.

and we will be happy to accommodate.

Yours very truly,

Network and not involving negligence or wrongful acts or omissions on the part
of ITI.

The Communication Services to be provided under this Agreement are set forth
in detail under ITI's response dated July 1, 1998, to the Corporation's RFP
dated June 15, 1998, which are incorporated herein by reference. In general,
the services will include the following:

-    Services - The digital recording and automated replay of teleconference
     calls originating at the Corporation's Westminster, Colorado, and Canadian
     operations. The service includes the recording and storage of all calls as
     a back-up to analog taping carried out by the Corporation.

-    Storage - All calls, whether scheduled for replay or not, shall be
     available on the system for retrieval for a period of 30 days from the date
     of recording or, in the event of replay, 30 days after the expiration of
     the replay, within two business hours.

-    Recordings, in any format, will be removed from all media and destroyed no
     earlier than 60 days and no later than 90 days after the expiration date of
     each conference call.

-    Reporting - The call detail reporting format will be determined by the
     Corporation and may be modified from time to time at the Corporation's
     request.

-    Management tools - ITI will develop an online session management interface
     (OSMI) providing the Corporation with the ability to remotely manage all
     aspects of the replay of each conference call, from set-up to tear-down.
     Details of OSMI are set forth in the ITI response at item 4.2.1.1.

-    Internet replay - ITI will design, develop and host a web site for the
     Corporation dedicated to the replay of audio teleconferences through the
     Internet. ITI will modify and enhance this dedicated web site from time to
     time at the Corporation's request.

SERVICE STANDARDS

1.   The service will initially be provisioned with 288 dedicated ports provided
     by the following carriers:

          Frontier Communications   8 long distance TIs
          AT&T                      2 long distance TIs
          TCG                       2 local access TIs

2.   ITI will perform all technical development, testing, installation and
     operation of Corporation's system according to the specifications outlined
     by the Corporation.

3.   ITI has configured the dedicated system to allow routine maintenance and
     the addition of system hardware without any interruption of service. If any
     interruption of the service is anticipated, ITI will inform the Corporation
     of such interruption (if possible) before interrupting service to ensure
     that call volume loss is minimized.

4.   ITI has configured the existing hardware and software for maximum fault
     tolerance and redundancy and, in the event of equipment malfunction or
     failure, general service should not be interrupted, although total capacity
     will be reduced until repairs to the system have been completed. ITI will
     provide its best efforts to replace any lost capacity as quickly as
     possible.

<PAGE>   6
5.    ITI will provide technical support for any and all issues arising from the
      ITI equipment and the operation of the Communication Services to be
      provided under this Agreement at no additional cost to the Corporation.

6.    ITI has preconfigured hot spare work stations to replace any failed
      machines. ITI has two highly fault-tolerant servers and a spare server
      that is synchronized nightly with the other servers. This system includes
      an auto-loading SCSI tape backup system that can store 96GB of data. ITI
      performs daily incremental backups and weekly full backups of all data
      with tapes being archived off-site.

7.    All call usage and billing data shall be available to the client within
      one hour of request during usual business hours.

8.    ITI has dedicated systems-support staff that performs monthly maintenance
      on all machines during non-peak hours. ITI disconnects each machine, one
      by one, and runs a full set of diagnostics. This consists of checking
      hard drives for logical and physical errors and running both high- and
      low-level diagnostics on all system components (such as controller cards,
      T1 cards, RAM, etc.).

9.    All recordings are stored digitally into 8-bit U-law dialogic VOX format
      at a sampling rate of 8,000Hz.

10.   All hardware and software are prequalified for Y2K compliance. Software

SERVICE TICKET CLASSIFICATION

       1. Priority 1: (Critical) The Post View system is down and conference
          customers cannot listen to and or record conferences. Restoration
          will occur as fast as humanly possible with an objective of 15
          minutes or less.

       2. Priority 2: (Major) Fifty percent or more of the system is unavailable
          for any reason. System is still functional but capacity is severely
          reduced. Restoration will occur as fast as humanly possible with an
          objective of 1 hour or less.

       3. Priority 3: (Minor) Any condition that results in the Post View
          system performing at less than optimal performance. This includes;
          slow performance during administration, recording, and replay, 1 or
          more voice communications lines down, 1 or more IVR workstations
          down, disk space reaches 85 percent of capacity, any other trouble
          that results in degradation in performance. Restoration will occur as
          fast as humanly possible with an objective of 3 hours or less.

     BUG TICKET CLASSIFICATION

       1. Priority 1: (Critical) Any code error or violation in the Interactive
          Telesis developed applications or databases that results in the Post
          View system being unavailable. Repair will occur as fast as humanly
          possible with an objective of 15 minutes or less.

       2. Priority 2: (Major) Any code error or violation in the Interactive
          Telesis developed applications or databases that results in the Post
          View system operating at a reduced capacity. Repair will occur as
          fast as humanly possible with an objective of 1 hour or less.

       3. Priority 3: (Minor) Code errors or violations in the Interactive
          Telesis developed applications or databases that should be fixed to
          enhance service or improve performance. Repair will occur according
          to a scheduled implementation plan after a significant amount of
          testing has occurred.

       4. Priority 4: (warranted) Errors in software developed by companies
          other than ITI and used to host the Post View system, e.g. bugs in
          Microsoft or any other commercially available software. Repair will
          occur in accordance with the software manufacturer's bug fixing plan.

SYSTEM MAINTENANCE

Whenever possible any system maintenance will be performed in a non-intrusive
manner consistent with insuring maximum availability of the Post View system.
Where available software utilities will be used to automate and enhance the
maintenance procedures. A framework like Unicenter TNG or HP OpenView will be
used to monitor and report on system health and performance. Additional tools
will be deployed to build a layered approach to maintenance. All automated
maintenance will occur as background processes and have no effect on system
performance. The first line of defense is the monitoring of system performance
and capacity. The second line of defense is the proactive maintenance of the
system on a scheduled basis. The third line of defense is the exception
maintenance conducted just before peak periods to insure maximum availability
of the Post View application. All maintenance will be performed under the
supervision of the Manager, Corporate Systems who is directly responsible for
all corporate systems. Technicians qualified on the monitoring and maintenance
procedures of Interactive Telesis will perform monitoring and maintenance.
These steps are detailed below:

DISK MAINTENANCE

All disks will be maintained in the readiest state available.

-    On RAID arrays the PERC Flexible Array Storage Tool (FAST) or the PERC SC
     RAID Console utility is to be used for consistency monitoring of the
     array. Monitoring will be continuous and a specific consistency check will
     occur at 12:00 AM every Saturday night.

-    A hot swappable standby drive will be ready on all RAID 5 configurations
     in case of a drive in the array failing.

-    Consistency checks will be performed on non-RAID disk drives using,
     Executive Software's, NT utilities. This will occur nightly with full
     defragmentation of the drives occurring every Sunday at noon.

NETWORK MAINTENANCE

All network cabling, switch, and hub equipment is maintained on a scheduled
basis.

-    Wire management trenches are used to route cabling away from traffic areas.

-    Cables will be labeled to identify the devices connected to them. This
     list will be maintained in an excel spreadsheet.

-    Cables will be inspected on a quarterly basis for fraying, cracking, and
     loose connectors. Damaged cables will be replaced immediately.

-    Switches will be maintained and monitored through the Network Node
     Management station. During peak periods, a sniffer may be deployed to
     determine if any bottlenecks are occurring in the network or transport
     layer. Corrective action will be taken immediately to relieve any
     occurrences of above items.

                                       4

<PAGE>   14
OTHER DEVICES

     .    Board diagnostics are performed on a quarterly basis for all Dialogic
          240SC T1 cards.

     .    Network interface cards will be monitored via SNMP and replaced
          immediately if performance drops below 85% of advertised capability.

     .    Backup tape drives are cleaned after every 80 hours of usage.

     .    UPS are maintained in accordance with the manufacturer's suggested
          maintenance plan.

     .    CSU's will be monitored via RMON probes and the network management
          station.

DATABASE MAINTENANCE

     All databases have a weekly scheduled maintenance plan run by the SQL
     Agent.

     .    Transaction logs are dumped nightly at 1:00 AM to a backup device
          (disk). During this process a consistency check and file resizing will
          occur.

     .    Databases are dumped to a backup device daily at 12:00 midnight for
          user databases and 1:00 AM for system databases. Consistency checks
          are performed before databases are being dumped.

     .    Query optimization and analysis tools are enabled to allow SQL 7.0 to
          performance tune itself automatically.

     .    Databases are configured to grow by 10% when needed and all logs are
          truncated on checkpoint. Performance monitoring and index resizing
          recommendations are written to a file for analysis and implementation
          at the appropriate time and place.

     .    Transactional replication occurs "in real time" to the backup database
          server and is designed to take over if the primary server fails.

VIRUS PROTECTION

     The Post View system is a partially closed loop system with connectivity to
     the Internet via a firewall. System management is achieved via VPN PPTP
     connection over the Internet. There will be no direct downloads of files or
     software to the Post View file servers. Only "shrink wrapped" software,
     voice files, and ITI application code will be installed or copied to the
     Post View system. This will significantly reduce the potential for viruses
     effecting system availability. Additionally the following will occur:

     .    McAfee Netshield and Webscan X are installed and running on the
          Firewall.

     .    A scheduled full scan of all server logical volumes will occur, from
          the firewall, every Tuesday starting at 11:00 PM.

     .    All IVR machines will be scanned on a monthly rotation. Three machines
          per week rotating so that each machine gets a full scan at least once
          per month. Only the Post View IVR applications will be installed on
          the IVR workstations. No other files or software will be installed, on
          the workstations, with the exception of diagnostic utilities.

                                       5

<PAGE>   15
   -  If a virus is introduced to a system, that system will be physically
      disconnected from the network (LAN cable unplugged from the NIC) and
      manually cleaned of the virus. If the Manager, Corporate Systems cannot
      certify the system clean then the drive will be formatted and the machine
      rebuilt.

   -  An incident report will be generated and submitted to the Manager,
      Corporate Systems within 1 hour of a suspected or confirmed virus
      incident.

SYSTEM BACKUP

   Without exception, all logical volumes on the servers will have a weekly full
   backup and a daily incremental backup. Tapes are changed on a grandfather,
   father, and son rotation. Archive jobs will be run on an as needed basis
   depending on system volume.

   -  Full backups with verify will occur every Thursday starting at 12:30 AM.
      All volumes are written to tape at this time.

   -  Incremental backups with verify will occur every day except Thursday at
      12:30 AM. Only files that have been changed since the last full backup or
      incremental backup are written to tape at this time.

   -  The backup operator is responsible for reviewing the backup reports to
      insure complete and verifiable backups.

   -  Tapes are secured in an Underwriters Laboratory (UL) approved fire proof
      safe both on site and off site. The current working set in the auto
      loader, second most current in safe on site, third most current in safe
      off site, fourth set in off site storage location.

   -  One month of normal and incremental tapes will be available for
      restoration. Archive tapes are kept for 6 months from date of archive
      before being recycled.

   -  Manager, Corporate Systems is directly responsible for management and
      implementation of the data storage procedures.

   -  During normal business hours, the NOC will be alerted electronically if a
      back up job fails. During non-business hours the on call technician will
      be paged.

   -  In the event of critical data loss the most current full backup will be
      restored to the disk and current incremental tapes restored to bring the
      system up to the existing storage level. The Manager, Corporate Systems
      will closely monitor this procedure to insure accurate and rapid
      restoration of all corrupted data.

   -  The Network Administrator will coordinate and monitor the restoration of
      individual files on an as needed or requested by the Post View
      administrators.

SYSTEM MONITORING

All critical functions of the Post View system will be monitored on a 24/7
basis. This includes LAN throughput, CPU utilization, storage capacity, memory
allocation, database performance, network availability (T1 lines), capacity, and
general system health. Since our Network Operation Center (NOC) does not operate
on a 24/7 basis, the Computer Associates Framework (Unicenter TNG subset) is the
monitoring tool set we use. From 7:00 AM until 6:00 PM Monday through Friday
(normal operating hours) the NOC will be responsible for system monitoring and
maintenance. All other times the on call technician will be responsible for
system monitoring and maintenance. Alerts are programmed to trigger events at
the warning stage and to page the on call technician during non-business hours.

o    Weekly reports will be submitted to the Manager, Corporate Systems for
     review. Reports will include storage capacity, intraday system capacity,
     performance matrix, and any other general information pertinent to the
     operation of the system.

o    Alerts have 4 thresholds for reporting purposes;

     1.   Critical: System has had a major malfunction and system is down.

     2.   Warning: An abnormal condition has occurred, however the system is
          still functional. The system will alarm in the NOC during normal
          business hours or page the on call technician during off business
          hours.

     3.   Informational: Event has occurred and information is being logged
          detailing the event. System is fully functional.

     4.   Exception: An event has occurred but no information was logged. A
          dialog box may appear for administrative intervention, however no
          data is logged to the event log. System is fully functional and no
          abnormal condition has occurred.

o    The Network Administrator reviews all event logs on a weekly basis for
     recurring events and unusual conditions. Additionally, the event logs are
     saved to a monthly folder every week and cleared in the on-line event log.

o    Manager, Corporate Systems reviews monthly event folders and will submit a
     quarterly system status report to the Director of Operations.

o    Immediate action will be taken by either the NOC or the on call technician
     to resolve events reported by the monitoring utilities.

o    If any server volume reaches 85 percent of capacity additional storage
     will be added "on the fly" using the FAST tool to initialize the stand by
     drive.

o    Any unusual or abnormal conditions are to be reported to the Network
     Administrator and the Manager, Corporate Systems as soon as possible after
     the event.

SYSTEM SUPPORT

Post View system support is provided via our "PartnerSupport.net" solution
support operation. This new value added service is designed to "surround our
customer in service". It consists of a web site, email support, and an 800
number (1-888-833-4378). We will use it to track all issues and bugs related to
the Post View system. You will receive an issue tracking number and be able to
get status updates via the web site. Future enhancements include access via the
"OSMI" as well.

PROCEDURES

When an issue arises with the Post View system, a service request will be
submitted to the ITI partner support group. The first level technician will
take down pertinent information, open a ticket and perform preliminary
troubleshooting procedures to determine if the issue is on the LAN or the
telecommunications network. If the problem resides on the telecom network, the
Frontier Confertech Network Management Center (NMC) will be conferenced into
the call and the issue will be gracefully passed to them for resolution with
the long haul carriers. If the issue is determined to be within an ITI managed
network the following will occur.

o    A case number is assigned in the system and user contact information will
     be entered. A detailed description of the issue will be entered and the
     issue is prioritized based on the service ticket classification explained
     in the previous section.

o    For priority 1 issues, the NOC will be notified of the issue as fast as
     humanly possible with an objective of 15 minutes or less. If the incident
     occurs after hours the on call technician will be notified immediately via
     alphanumeric paging. The objective being to return the system to
     operational status ASAP.

o    For priority 2 issues, the same steps will be taken as in priority 1
     however, the ticket will be passed through normal communications channels
     with resolution being 1 hour or less. If the issue occurs after hours the
     on call technician will receive an alert page and will continue
     troubleshooting procedures to determine what level of repair needs to be
     accomplished immediately. If service is performing at an acceptable level,
     the repairs will commence at the start of the next business day. The
     Manager, Corporate Systems will make the decision when determining if a
     system is performing at an acceptable level.

o    For priority 3 issues, a ticket will be opened and a case number assigned
     to the Network Administrator for resolution. The Network Administrator
     will assess the situation, determine the best course of action, and
     schedule the repair of the issue to insure no interruption of service.

o    The same procedures will apply for software bug tracking as well.
     Additionally, a priority 4 bug will be recorded and submitted to the
     appropriate software vendor for analysis and resolution in accordance with
     their established procedures.

o    Priority 1 and 2 software bugs will be addressed immediately, priority 3
     and 4 bugs will be implemented on a mutually agreed upon schedule.

                                       8

ESCALATIONS

     All escalations will occur automatically at pre-determined times. Frontier
     Confertech and Interactive Telesis employees may request escalation of an
     issue if they feel it is warranted. It is important to note that if all
     issues are submitted as priority one tickets then priority one issues
     become normal an the effectiveness of the escalation process is diminished.
     If service level and responsiveness is not meeting your expectations,
     please do not hesitate to contact the Director of Operations at
     760-704-4345. All escalations will go from a first level technician to the
     next appropriate person in the process.

     -    Priority 1 issues are escalated to the Manager, Corporate Systems if
          not resolved within 30 minutes of ticket issue.

     -    Priority 2 issues are escalated to the Network Administrator if not
          resolved within 3 hours of ticket issue. If the issue is not resolved
          within 6 hours, the issues are escalated to the Manager, Corporate
          Systems.

     -    Priority 3 issues are escalated to the Network Administrator if not
          resolved within 6 hours of ticket issue. If the issues are not
          resolved by next business day, the issues are escalated to the
          Manager, Corporate Systems.

     -    Priority 1 bugs are escalated to the Director, It if not resolved

SYSTEM CAPACITY PLANNING AND UPGRADE

       All system upgrades are scheduled to avoid confusion and downtime.
       Coordination between the Post View administrators and Interactive
       Telesis is critical to a successful upgrade. System and storage capacity
       reports will be reviewed regularly, by the management team, to analyze
       trends and better prepare for peak seasons.

       -  When storage reaches 65 percent of capacity, the Network administrator
          will institute the standing PO for a new hot swappable hard drive. At
          85 percent full the standby drive is initialized and added to the
          file systems logical volume. When the replacement drive is received,
          it will be put into the standby bay and low level formatted.

       -  An archive program will be run at least 3 times per week to move
          expired voice files to the alternate file system for backup to an
          archive tape and deletion from the system.

       -  When incoming T1 ports reach 75 percent of capacity, provisioning for
          additional port capacity will occur. Additional capacity will be
          captured from existing IVR systems and or standby IVR workstations
          may be deployed to meet capacity during peak system usage.

       -  Analysis of usage will occur quarterly and after every "IR season" to
          determine capacity and plan for the next period of heavy usage.

       -  IVR Application upgrades will be categorized as either an enhancement
          or a fix to an existing problem. Bug fixes will be thoroughly tested
          in a development environment and then ported to 1 or 2 production
          IVR's. Once the fix has been validated on the product system the
          remainder of the IVR's will be brought up to the latest build and a
          new release will be generated.

       -  The same procedures apply for software enhancements, the only
          difference being a new version is generated instead of a new release.
          Additionally, enhancements are to be scheduled outside of the bug
          tracking system.
