Dear Lisa:

As requested, enclosed is the Record and Replay Communication Services
Agreement (in triplicate) executed by Interactive Telesis. Would you please
provide one fully executed copy to the undersigned at your convenience.

You will note that we have added the PostView Support and Maintenance Section of
our Business Continuity Plan as Attachment C to the Agreement. I think you will
find this addendum will cover the issues that were raised earlier and for which
Frontier wanted more specific detail than set forth in our Best Practices
document. If you would like any amendments to Attachment C, just let us know
and we will be happy to accommodate.

Yours very truly,

/s/ DONALD E. CAMERON

Any objections or disputes concerning invoices shall be resolved in accordance

3.   AUDIT

     ITI shall maintain accurate and complete records of all recording and
replay usage for which payment under this Agreement is to be computed. Such

practices so they may be readily audited and shall be held until costs have

payments as the case may be has been made. ITI shall permit Corporation or
Corporation's Representative to examine and audit these records and all
supporting records at all reasonable times. Audits shall be made not later than
two (2) calendar years after the completion of services rendered pursuant to
this Agreement.

4.   REPORTING

     ITI shall provide usage and billing reports in the format(s) and time
intervals required by the Corporation. ITI shall, at the Corporation's request,
provide secured online call management and call usage access to the Corporation

5.   TITLE TO WORK PRODUCTS

     All right, title and interest in and to all tangible and intangible work
and work products developed or produced under this Agreement by or on behalf of
ITI for the Corporation, whether comprising or incorporated in specifications,
samples, data, computer programs, reports, documentation or other technical or
business information, and all right, title and interest in and to patents,
copyrights, trade secrets, trademarks and other intellectual property derived
from such work and work products are the property of ITI. This Provision shall
not apply to the Corporation's confidential information that may be contained
in the work product.

6.   WARRANTIES

     ITI agrees that it shall provide, in connection with the services provided
pursuant to this Agreement, the standard of care, skill, and diligence normally
provided by a vendor in the performance of similar services and that all such
services shall be performed in accordance with sound and accepted industry
standards and practices. If ITI fails to meet such standards of care, skill and
diligence set forth in this section, ITI shall be liable for all direct damages
caused thereby.

     ITI has developed a Business Continuity Plan (the "BCP") which addresses
issues relating to system maintenance, back-up, and disaster recovery relating
to the services to be provided hereunder. The BCP details ITI's procedures and
is attached hereto as Exhibit "C" and incorporated by reference herein.

7.   YEAR 2000

     ITI warrants that all services, including any software or data processing
support, data exchanges or systems of any kind used by ITI to support
performance of the services, shall be Year 2000 Compliant, as defined below.
This warranty begins upon the commencement of the service and shall continue
thereafter until March 31, 2001, or the expiration of any other warranty period
applicable to the service, whichever is later. In the event of a breach of this
warranty, Corporation shall have any and all rights and remedies provided at
law or in equity. Upon receiving notice thereof, ITI shall promptly correct any
breach of this warranty, including correction of any invalid data or
information resulting therefrom.

     "Year 2000 Compliant" means proper performance of any service which is
dependent upon or involves calendar dates before, during and after the Year
2000, including both single century and multi-century formulas, leap year
capabilities and transition from the year 2000 to the year 2001. "Proper
Performance" means the service will not cause an abnormal ending scenario or
generate incorrect values involving dates.

8.   INDEMNIFICATION

     A.   By Corporation. The Corporation shall indemnify and hold harmless ITI
and any affiliated companies from and against any and all claims, damages, or
liability, including reasonable attorneys' fees and the costs and expense of
any legal action, or prelude thereto, for libel, slander, invasion of privacy,
securities law violations, improper trade practices, illegal competition,
infringement of copyright or licenses (if not covered under Section 14
hereof), or any other wrongful conduct resulting from the dissemination of any
information provided by customers of the Corporation and made available on the
Network and not involving negligence or wrongful acts or omissions on the part
of ITI.

     B.   By ITI. ITI shall indemnify, defend and hold harmless Corporation
from and against any claims, damage or liability including reasonable attorneys
fees and the costs and expenses of any legal action, or prelude thereto,
arising as a result of the negligence or wrongful acts or omissions of ITI, its
officers, employees or agents in performing any services for Corporation
pursuant to this Agreement, including, without limitation, claims under Sections
7 and 14 hereof.

     C.   Survival. The provision of this paragraph shall remain effective and
inure to the benefit of the respective parties notwithstanding the expiration,
cancellation, or termination of this Agreement.

9.   TERMINATION

     Either party may cancel this Agreement at any time by giving the other
party 30 days' written notice thereof and specifying the effective date of such
cancellation. ITI may cancel this Agreement if the Corporation has failed to
make any payment when due pursuant to this Agreement upon giving 30 days'
written notice to Corporation and the Corporation does not cure such failure
within 10 days after receipt of ITI's written notice thereof.

10.  GOVERNMENTAL REGULATION

either presently in existence or enacted, made or enforced hereafter, including

written consent of the other, which consent shall not be unreasonably delayed

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,
unless the arbitrator rules otherwise, 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

<PAGE>   4
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.

13.  WAIVER

     The failure of either party to this Agreement to object to, or to take
affirmative action with respect to, any conduct of the other which is a
violation of the terms of this Agreement shall not be construed as a waiver of
such violation or breach, or of any future breach, violation, or wrongful
conduct.

     ITI warrants that the service provided hereunder does not infringe upon or
violate any patent, copyright, trade secret, or any other proprietary right

name. ITI shall pay all damages and costs (including reasonable attorney fees)
whether or not such claim is successful or awarded against Corporation.

15.  EQUAL OPPORTUNITY

because of race, religion, color, sex, age, or national origin. ITI will take
affirmative action to ensure that applicants are employed, and the employees are
treated during employment without regard to their race, religion, color, sex,
age, or national origin. Such action shall include, but not be limited to, the
employment, upgrading, demotion, or transfer; recruitment or recruitment
advertising; layoff or termination; rates of pay or other forms of compensation;
and selection for training, including apprenticeship. ITI agrees to post in
conspicuous places, available to employees and applicants for employment,

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

     by the following carriers:

          Frontier Communications   8 long distance TIs
          AT&T                      2 long distance TIs

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

     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.

      machines. ITI has two highly fault-tolerant servers and a spare server
      that is synchronized nightly with the other servers. This system includes

      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.

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.

                                       7

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
          within 30 minutes of ticket issue.

     -    Priority 2 bugs are escalated to a Sr. Developer if not resolved
          within 6 hours of ticket issue. If the bugs are not resolved within 3
          days, the bugs are escalated to the Director, IT.

     -    Priority 3 bugs are not escalated through the normal escalation
          process. They will be identified and scheduled for correction through
          the Director, IT.

     -    Priority 4 bugs will not be tracked through the system however, they
          will be logged with the MSDN for evaluation.

KEY CONTACTS

     Primary point of contact for service and support will be the
     PartnerSupport.net group. This may be via email, Internet, and 800 number.

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.
