                  Cellnet shall investigate any such concerns, and (1)
                  explain why the issue is not reasonably likely, in
                  Cellnet's reasonable discretion, to have a material
                  adverse impact on the AMR Services, or (2) provide a
                  reasonable plan and timeline to address these concerns or
                  issues in a manner reasonably acceptable to Parties.

1.4      Initial Fixed Network Deployment Phase Testing.
         ----------------------------------------------

         (a)      Comparison of Reads. During the Initial Fixed Network
                  -------------------
                  Deployment Phase, Laclede will obtain and compare the
                  manual reads from the Test Meters to the automated meter
                  reads provided by Cellnet pursuant to Section 1.3(e)
                  above. Any deviations between the manual and automated
                  readings will be investigated by both Parties in good
                  faith and resolved within two (2) Business Days.

         (b)      Substitute Meters. Any residence with access issues, meter
                  -----------------
                  problems or other circumstances that interfere with the
                  Initial Fixed Network Deployment Phase will be dealt with
                  on a case-by-case basis. An alternate address within the
                  coverage area described in Section 1.2(a) may be
                  substituted for the remainder of the Initial Fixed Network
                  Deployment Phase, or, in the alternative, the MIU will be
                  subtracted from the sample population, at Laclede's
                  discretion.

         (c)      Network Coverage. Cellnet will be responsible for Fixed
                  ----------------
                  Network infrastructure coverage issues and will use
                  commercially reasonable efforts to resolve any Fixed
                  Network infrastructure coverage issues promptly, as
                  necessary, to perform the AMR Services.

1.5      Initial Fixed Network Deployment Phase Performance Standards.
         ------------------------------------------------------------

         (a)      Summary of Readings. During the Initial Fixed Network
                  -------------------
                  Deployment Phase, Cellnet shall provide Laclede: (i) daily
                  automated meter reads in hundreds of cubic feet; and (ii)
                  a monthly summary of MIU performance, by address. The
                  individual meter readings will be maintained by Cellnet
                  daily and delivered to Laclede on the next Business Day.
                  Daily and monthly overall performance indicators should be
                  included in the summary.

         (b)      Areas of Emphasis. Close scrutiny will be given to
                  -----------------
                  Cellnet's performance in the following areas:

                  (i)      Project Management;
                  (ii)     Integration Support Services
                  (iii)    Data Acquisition and Delivery;
                  (iv)     Operations and Maintenance;
                  (v)      Customer Service;
                  (vi)     Technology; and
                  (vii)    Data Center Operations.

        At any time during the Initial Fixed Network Deployment Phase,
        Laclede may notify Cellnet in writing that Laclede has concerns
        regarding any of the foregoing areas, and

                                     4

                  Cellnet shall investigate any such concerns, and (1)
                  explain why the concerns are not reasonably likely, in
                  Cellnet's reasonable discretion, to have a material
                  adverse impact on the AMR Services, or (2) provide a
                  reasonable plan and timeline to address these concerns in
                  a manner reasonably acceptable to the Parties.

         (c)      MIU Validation. During the Initial Fixed Network
                  --------------
                  Deployment Phase, the Test Meters will be automatically
                  read every day to determine accuracy, network
                  deliverability, and ability to transfer data between the
                  Parties' systems based on the Standard Interface
                  Specifications. During the Initial Fixed Network
                  Deployment Phase, the Parties will work together to
                  validate and correct promptly any errors in the following
                  areas:

                  (i)      Fixed Network reading does not correlate with
                           visual index reading. This deviation will take
                           into account rounding errors and time
                           differences. Cellnet must correct programming
                           errors on a MIU.

                  (ii)     Fixed Network reading was not available through
                           the network during the scheduled reading period.
                           This failure takes into account MIUs that fail to
                           communicate to the Fixed Network due to device
                           problems.

                  (iii)    MIU is found to be in an alarm state and the
                           appropriate flag was not returned.

                  (iv)     MIU is found to be sending inconsistent readings
                           when other MIUs in the area are responding
                           correctly.

                  (v)      The meter installation data and the Laclede Gas
                           Data transferred between Laclede and Cellnet
                           shall be validated and consistent with the
                           Standard Interface Specifications for use within
                           the respective Parties' systems. In the event
                           that the data is not in the correct format, the
                           non-complying Party shall make the correction at
                           its own expense.

                                  ARTICLE 2

                           2.2(g); and

                  (v)      The software to manage the Fixed Network Data.

         (c)      Installation of the AMR Services System and Components.
                  ------------------------------------------------------

                  (i)      AMR Services System. During the Deployment
                           -------------------
                           Period, Cellnet shall install, and/or contract
                           with subcontractors for the installation of, the
                           Fixed Network and the various components thereof.
                           Cellnet shall, or cause its subcontractors to,
                           deploy an adequate number of field supervisors at
                           all times to ensure that installers have ready
                           access to supervisors as and when needed to
                           address issues and receive information in a
                           timely manner. The Cellnet program manager and
                           the Laclede AMR program manager will establish
                           introduction meetings and regularly scheduled
                           project review meetings. A pre-installation
                           meeting will be held among Cellnet, the MIU
                           Installer, and Laclede for the purpose of
                           reviewing all matters of mutual concern to ensure
                           that the installation plan will be met.

                  (ii)     MIUs. Cellnet and Laclede will develop and agree
                           ----
                           upon the various Routes and schedules for
                           installation of the MIUs on existing Laclede Gas
                           Meters at residences and businesses within the
                           Fixed Network Area. Installers shall work during
                           normal working hours of 8:00 a.m. to 5:30 p.m.
                           Monday through Saturday, which hours shall be
                           adjusted to accommodate extended daylight hours.
                           Additionally, it shall be acceptable for
                           installers to install MIUs outside these hours
                           pursuant to previously made appointments with
                           customers. Cellnet shall not be required to
                           install a MIU on a meter unless the meter can be
                           retrofitted to accept the MIU. The Parties agree
                           that all of the meters listed on Exhibit 5-A can
                                                            -----------
                           be retrofitted to accept a MIU; provided that
                           access to the meter is not obstructed or the
                           physical condition of the meter is such that it
                           does not prevent such retrofitting without
                           requiring major repair. The

                                     6

                           Parties shall cooperate in good faith to
                           determine whether the meters listed on Exhibit
                                                                  -------
                           5-B can be retrofitted to accept a MIU. Cellnet
                           ---
                           will manage all installation functions necessary
                           to establish and maintain a fully functional
                           Fixed Network, which shall include, without
                           limitation, installing the MIUs and successful
                           transmission of automated meter readings or
                           alarms to the NOC indicating that the MIU has
                           been successfully installed on a Laclede Gas
                           Meter. Cellnet shall transfer such data regularly
                           to Laclede. During the Deployment Period, Laclede
                           shall provide to Cellnet Laclede's projected
                           monthly meter reading schedule at least ninety
                           (90) days in advance of each respective Billing
                           Window. The following steps and procedures will
                           be followed for installation of the MIUs:

                                    --------------------
                                    installation of MIUs on a Route, Laclede
                                    will promptly notify the customers on
                                    the Route (by flyers, radio or TV
                                    announcements or other reasonable means)
                                    of the planned installation of MIUs on
                                    meters servicing their residence or
                                    business. Cellnet or the MIU Installer
                                    shall contact the occupants of each
                                    affected property to make the necessary
                                    appointments and arrangements to install
                                    the MIUs. For meters that require entry
                                    into the property, the MIU Installer
                                    shall attempt to contact the occupant of
                                    the property by telephone, letter or
                                    door hanger and in person, on six (6)
                                    separate occasions (at least two (2) of
                                    which occasions must be personal visits
                                    to the property) and shall offer the
                                    occupant a choice of reasonable
                                    appointment times (i.e., specific
                                    appointment times or small time
                                    windows). The MIU Installer shall time
                                    its various attempts to contact an
                                    occupant via telephone, letter and in
                                    person so as to have the greatest
                                    probability of successfully contacting
                                    the occupant and installing the MIU. For
                                    purposes of clarity, an unanswered
                                    telephone call constitutes an attempt.

                           (B)      Laclede Appointments. If the MIU
                                    --------------------
                                    Installer is unable to gain the
                                    necessary access to a meter after the
                                    six (6) occasions specified in Section
                                    2.1(c)(ii)(A), Cellnet will so advise
                                    Laclede in writing as soon as reasonably
                                    practicable. After receiving such
                                    written advisement, Laclede will attempt
                                    to contact the occupant and/or owner of
                                    the property and work with Cellnet to
                                    arrange an appointment for Cellnet to
                                    install a MIU. If the occupant and/or
                                    owner miss a scheduled appointment or
                                    the meter is not an Accessible Meter for
                                    any other reason, Laclede will attempt
                                    to once again make contact with the
                                    occupant and/or owner and work with
                                    Cellnet to reschedule the appointment.
                                    If the MIU Installer is not able to
                                    install a MIU on the second or
                                    subsequent appointment made by Laclede,
                                    then Laclede shall reimburse Cellnet for
                                    its actual direct expenses without
                                    mark-up for the visit, not to exceed
                                    Twenty-Five Dollars ($25.00).

                  (iii)    Additional MIUs.
                           ---------------

                           (A) Cellnet shall from time to time during the
                           Term, at no additional cost to Laclede
                           (including, but not limited to, shipping fees and
                           the manufacturers' cost to handle and install a
                           MIU on a meter, which costs will be paid by
                           Cellnet; provided, however, that all such
                           shipping costs and manufacturers' costs shall be
                           actual direct costs without mark-up by Laclede),
                           make MIUs available to the manufacturers
                           supplying meters to Laclede at a time and in a
                           volume and manner that will allow the
                           manufacturers to install the MIUs on the meters
                           during assembly at the manufacturers' facilities.
                           Laclede shall provide Cellnet at least 120 days'
                           prior written notice with regard to what number
                           of, to what manufacturers and when MIUs are to be
                           provided. Cellnet shall throughout the Term
                           provide to the respective manufacturers MIUs for
                           the types of meters listed on Exhibit 5-C.
                                                         -----------
                           Additionally, Laclede and Cellnet will cooperate
                           with regard to the coordination of meter model
                           changes in an effort to ensure availability of
                           MIUs for various meter models.

                           (B) During the Deployment Period, Cellnet shall,
                           at no additional charge to Laclede, make MIUs
                           available to Laclede's meter manufacturers in the
                           manner described above in this Section for
                           installation on new meters that Laclede will use
                           to replace certain of the meters within its
                           system that cannot be retrofitted with a MIU.

                           (C) In addition to the foregoing MIUs, Cellnet
                           shall from time to time, upon the request of
                           Laclede, make available to Laclede MIUs for
                           installation by Laclede on meters that Laclede
                           has removed from customers' premises and is
                           reconditioning in preparation for re-installation
                           at customers' premises. The MIUs described in
                           Subsection (B) above and this Subsection (C) are
                           included in the approximately 650,000 MIUs to be
                           provided by Cellnet during the Deployment Period.

                           (D) Notwithstanding the foregoing, Cellnet is not
                           required to provide a MIU to a manufacturer or to
                           Laclede directly unless Cellnet has an integrated
                           MIU available for the meter on which the MIU is
                           to be installed. At no additional cost to
                           Laclede, Cellnet and Laclede shall work together
                           in good faith to develop a MIU for the National
                           meters of the types listed on Exhibit 5-B in
                           Laclede's meter population that Cellnet cannot
                           currently retrofit with a MIU.

                           (E) Cellnet shall provide additional MIUs and
                           reading services to replace units retired and to
                           serve additional customers subject to the terms
                           and provisions of Exhibit 6, which is attached
                                             ---------
                           hereto and incorporated herein by reference.

                  (iv)     Existing Remote Device Removal. Many of Laclede's
                           ------------------------------
                           existing meters currently have a remote-type
                           device installed. Prior to any such device

                                     8

                           removal, Laclede shall provide any necessary
                           training to Cellnet regarding device removal,
                           including, without limitation, training regarding
                           handling of wires and cables. After device
                           removal, any attached wires and/or cables shall
                           not be removed, but trimmed back to be
                           unobtrusive. Any existing component on the
                           exterior of the premise shall be left in place.
                           One particular device, the American Meter TRACE
                           unit, is both salvageable and redeployable. The
                           MIU Installer will take reasonable care to return
                           each TRACE device to Laclede in the same state it
                           was in immediately prior to its removal. At
                           Laclede's expense, Laclede will provide the
                           proper containers and their transportation to and
                           from the MIU Installer for packaging the returned
                           devices. Any hazardous material component of the
                           meter or module removed from the field by Cellnet
                           or the MIU Installer during the installation of
                           MIUs shall be deposited in a container provided

                           the MIU installations/replacements. Cellnet shall
                           develop a Quality Assurance Plan that is
                           reasonably acceptable to Laclede and shall
                           perform, or require subcontractors to perform,
                           all MIU installation activities in accordance
                           with such plan. The Quality Assurance Plan shall
                           be provided by Cellnet to Laclede within thirty
                           (30) calendar days after the Effective Date and
                           shall include an audit feature that will track
                           the performance of individual installers. Laclede

                           general and/or security or safety violations. If
                           Laclede wishes to disqualify an individual
                           employed or used by such MIU Installer, it shall
                           notify Cellnet and provide reasonable details
                           regarding the grounds for such request. Cellnet
                           shall investigate the request and notify Laclede
                           of its determination promptly, but in all events
                           within five (5) Business Days, during which such

         (g)      Timeframe for Installation and Implementation.
                  ---------------------------------------------

                           (i) Meter Activation. Upon (1) the installation
                               ----------------
                           of MIUs on 90% of the Accessible Meters on a
                           Route, (2) for which Cellnet is receiving
                           designation and installation information via the
                           Cellnet Standard Interface, and (3) Cellnet is
                           utilizing the Fixed Network to gather and provide
                           successful readings to Laclede, Cellnet will
                           activate the Fixed Network with regard to this
                           Route and commence electronically reading the
                           meters on the Route. Cellnet will continue to
                           attempt diligently to install MIUs on any Laclede
                           Gas Meters on a Route which are not equipped with
                           a MIU as of the date Cellnet activates the Route.
                           Cellnet shall notify Laclede in advance of the
                           date that the electronic reads will commence for
                           a Route, and Laclede may, at its option, continue
                           to read manually all meters that it then
                           currently reads manually for one (1) full billing
                           cycle after such date in order to verify the
                           readings. For those meters that Laclede is not
                           then currently obtaining manual reads (i.e.,
                           meters equipped with a TRACE device), Laclede
                           shall use reasonable effort to obtain a manual
                           reading of such meters for one (1) full billing
                           cycle. If Laclede discovers any discrepancy
                           between the manual reading and the reading
                           rendered by the MIU, Laclede shall notify
                           Cellnet, and Cellnet shall promptly repair,
                           replace or reprogram the MIU if found to be
                           defective upon investigation, and thereafter
                           Cellnet shall manually read the meter or take
                           whatever actions are necessary to verify that the
                           MIU is functioning properly. Laclede's obligation
                           to pay the monthly fee per meter described in
                           Section 2.3(a) shall commence on the date the
                           electronic reads commence on a Route as described
                           in the first sentence of this section.
                           Cellnet shall provide manual monthly billing
                           reads pursuant to Laclede's projected monthly
                           meter reading schedule on Accessible Meters on an
                           activated Route that are not equipped with a
                           properly functioning MIU commencing the fortieth
                           (40th) day following the date such Route is

                                     11


                           activated. Cellnet shall not be required to
                           provide manual readings for any meters on which
                           Laclede instructed Cellnet not to install a MIU.

                           (ii) Entire System. MIUs shall be installed and
                                -------------
                           operational on 99% of Accessible Meters within
                           the Fixed Network Area within twenty-four (24)
                           months after the Effective Date ("Deployment
                           Deadline"). If Cellnet fails to perform its
                           obligations under this Agreement relating to
                           installation of the MIUs, and as a result the 99%
                           threshold is not reached by the Deployment
                           Deadline, then until such time as MIUs are
                           installed and operational on 99% of Accessible
                           Meters less Unavailable Meters within the Fixed
                           Network Area (or this Agreement is terminated, if
                           earlier), Cellnet shall provide monthly manual
                           billing readings pursuant to Laclede's projected
                           monthly meter reading schedule to Laclede on
                           Accessible Meters that are not equipped with a
                           MIU. Notwithstanding the foregoing, if, due
                           solely to the failure of Cellnet to perform its
                           obligations under this Agreement, MIUs are not
                           installed and operational on 99% of Accessible
                           Meters within the Fixed Network Area within six
                           (6) months after the Deployment Deadline, Cellnet
                           shall be in default under this Agreement, and
                           Laclede may avail itself of the remedies provided
                           in this Agreement for default by Cellnet.

         (h)      Mandatory Provisions in Cellnet's Leases and/or Financing
                  ---------------------------------------------------------
                  Documents. Cellnet shall use its commercially reasonable
                  ---------
                  efforts to cause the senior lenders to Cellnet who are
                  directly financing the build out of the Fixed Network, to
                  include in the financing agreements therefor provisions
                  providing that upon the occurrence, and during the
                  continuation, of any default of Cellnet under such
                  financing agreements, if the lenders under that financing
                  agreement determine in their sole discretion that such
                  action will not impair the Lender Group's ability to
                  enforce the obligations of Cellnet under such financing
                  agreements or realize upon the security collateral of the
                  lenders under such financing agreements, such lenders
                  shall engage in good faith negotiations with Laclede to
                  permit Cellnet or a third party selected by the Lender
                  Group to continue to perform Cellnet's obligations under
                  this Agreement; provided, however, that the foregoing
                                  --------  -------
                  shall in no way prohibit such lenders from pursuing any of
                  their rights or remedies under such financing agreements.

         (i)      St. Louis Office. During the Term, Cellnet shall maintain
                  ----------------
                  an office in the St. Louis metropolitan area staffed with
                  a sufficient number of employees or contract employees to
                  fulfill its obligations under this Agreement and a manager
                  who is responsible for servicing Laclede under this
                  Agreement.

2.2      Services to be Provided by Cellnet.
         ----------------------------------

         (a)      Daily Meter Reads. Cellnet shall provide to Laclede daily
                  -----------------
                  automated meter reads in hundreds of cubic feet on
                  Activated Meters.

         (b)      Reliability of Daily Consumption Readings. Cellnet shall
                  -----------------------------------------
                  provide daily automated meter reads in hundreds of cubic
                  feet for at least [**]% of the Activated Meters on
                  an averaged basis over the total number of calendar days
                  of each month and a minimum of [**]% of the
                  Activated Meters for each and every calendar day during
                  any Contract Year during the Term of this Agreement. This
                  reliability rate implies that the required percentage of
                  the meters are read electronically through the Fixed
                  Network.

         (c)      Reliability of Scheduled Consumption Readings for Monthly
                  ---------------------------------------------------------
                  Billing. Cellnet shall provide to Laclede monthly meter
                  -------
                  reads in hundreds of cubic feet on each Activated Meter.
                  These monthly meter readings shall be made available
                  during each Fixed Network Meter's respective monthly
                  Billing Window as established according to Laclede's
                  projected monthly meter reading schedule (as such schedule
                  may be adjusted by Laclede from time to time) at a
                  reliability rate of [**]% of the Activated Meters
                  for each month and a minimum of [**]% of the
                  Activated Meters for each respective billing day within
                  the month. If Cellnet is not able to achieve [**]%
                  of such monthly reads electronically, Cellnet shall
                  achieve the required percentage by providing Laclede
                  manual reads of Activated Meters within the Fixed Network
                  Area; provided that Cellnet shall provide to Laclede each
                  month an electronic list of the meters for which Cellnet
                  was not able to obtain an electronic read through the
                  Fixed Network. Cellnet shall promptly research and, if
                  practicable, correct any MIU that the Fixed Network is not
                  able to read electronically. In the event Laclede changes
                  or adjusts its billing cycle schedule during the Term,
                  Cellnet shall make all changes necessary to accommodate
                  such changes or adjustments within thirty (30) days after
                  receiving written notice of such change or adjustment from
                  Laclede; provided that if such changes or adjustments to a
                  billing cycle occur during the Deployment Period, Laclede
                  shall provide Cellnet 120 days prior written notice of
                  such change or adjustment.

         (d)      Reliability Penalty.
                  -------------------

                  (i)      If Cellnet is not able to achieve the respective
                           required average monthly reliability percentages
                           for daily reads set forth in Section 2.2(b) above
                           for any month during the Term, then Cellnet shall
                           owe to Laclede a penalty (the "Daily Reliability
                           Penalty") equal to [***************] Dollars
                           ($[******]) for each [********] percent
                           ([***]%) or portion thereof that Cellnet is
                           below the applicable threshold. Furthermore, if
                           Cellnet is not able to achieve the required daily
                           minimum percentages set forth in Section 2.2(b)
                           above on any day during the Term, then Cellnet
                           shall owe to Laclede a penalty ("Minimum Daily
                           Reliability Penalty") equal to [************]
                           Dollars ($[*****]) for each [********] percent
                           ([***]%) or portion thereof that Cellnet is
                           below the applicable minimum. For purposes of
                           calculating the Daily Reliability Penalty and the
                           Minimum Daily Reliability Penalty, only Activated
                           Meters on Routes that have been activated as
                           described in Section 2.1(g)(i) above for ninety
                           (90) days or more shall be considered. Anything
                           herein to the contrary notwithstanding, except
                           for any rights that

The information below marked by * and [] has been omitted pursuant to a request
for confidential treatment. The omitted portion has been separately filed
with the Commission.

                           may exist pursuant to Article 11 hereof,
                           Laclede's sole remedy for Cellnet's failure to
                           meet or exceed the foregoing performance metrics
                           is set forth in this Section 2.2(d)(i).

                  (ii)     The daily reliability performance percentages
                           shall be equal to the sum of each day's number of
                           successful automated daily meter readings which
                           Cellnet makes available to Laclede during the
                           calendar month, divided by the sum of each day's
                           number of daily Activated Meters. This
                           reliability rate implies that the required
                           percentage of the meters are read electronically
                           through the Fixed Network.

                  (iii)    Commencing the first calendar month ninety (90)
                           days after the Deployment Deadline, if Cellnet
                           fails to provide to Laclede monthly meter reads
                           in accordance with the reliability percentages
                           described in Section 2.2(c) above, during any
                           month, then Cellnet shall owe to Laclede a
                           penalty (the "Monthly Reliability Penalty") equal
                           to [****************] Dollars ($[******]) for each
                           [********] percent ([***]%), or portion
                           thereof, by which Cellnet is below such
                           [**]% threshold. For example, if Cellnet is
                           able to provide reads for only [**]% of the
                           Activated Meters during a month, then the Monthly
                           Reliability Penalty shall equal [***************]
                           Dollars ($[******]). Additionally, Cellnet
                           shall owe to Laclede a penalty ("Minimum Monthly
                           Reliability Penalty") of [************] Dollars
                           ($[*****]) for each [********] percent
                           ([***]%) or portion thereof by which Cellnet
                           is below the [**]% minimum on any billing
                           day. Anything herein to the contrary
                           notwithstanding except for any rights that may
                           exist pursuant to Article 11 hereof, Laclede's
                           sole remedy for Cellnet's failure to meet or
                           exceed the foregoing performance metrics is set
                           forth in this Section 2.2(d)(iii).

                  (iv)     The monthly reliability performance shall be
                           equal to the sum of each day's number of
                           successful monthly meter readings which Cellnet
                           makes available to Laclede during the calendar
                           month, divided by the sum of each day's number of
                           monthly Activated Meters.

                  (v)      The Daily Reliability Penalty, Minimum Daily
                           Reliability Penalty, Monthly Reliability Penalty
                           and Minimum Monthly Reliability Penalty shall be
                           referred to herein collectively as the
                           "Reliability Penalty." Laclede shall have the
                           right to deduct the Reliability Penalty amount
                           from the Fee for each such month during which the
                           daily and/or monthly reliability failures occur,
                           or any subsequent month.

         (e)      Historical On-Request Meter Reads / Off-Cycle Meter
                  ---------------------------------------------------
                  Readings. Cellnet shall provide access to a Cellnet
                  --------
                  website via the Internet in order to obtain the
                  thirty-five (35) most recent days of usage history
                  information for each Activated Meter. Additionally,
                  Cellnet shall provide Laclede with the ability to access
                  the most recent thirteen (13) months of consumption
                  readings for customer billing history information for each
                  such meter over the Internet.


                                     14

         (f)      Special Conditions Applicable to Certain Laclede Gas
                  ----------------------------------------------------
                  Meters. The parties acknowledge that there are
                  ------
                  approximately 10,000 Laclede Gas Meters within the portion
                  of the Fixed Network Area shown on Exhibit 7 ("MoNat
                  Manual Area Meters") for which Cellnet will not initially
                  be able to obtain reads utilizing the Fixed Network as a
                  result of the absence of the necessary MCCs and other
                  infrastructure. Notwithstanding the foregoing, Cellnet
                  shall install MIUs on the MoNat Manual Area Meters if
                  instructed to do so by Laclede and perform Manual Reads of
                  these meters monthly within their respective Billing
                  Windows. Such readings shall be transmitted to Laclede via
                  the Cellnet Standard Interface. The MIUs installed on the
                  MoNat Manual Area Meters shall be subject to the Monthly
                  Reliability Penalty and Minimum Monthly Reliability
                  Penalty described in Section 2.2(d) of this Agreement, but
                  not the Daily Reliability Penalty and Minimum Daily
                  Reliability Penalty described in Section 2.2(d). Except to
                  the extent specifically provided herein, all of the MIUs
                  installed on MoNat Manual Area Meters shall be subject to
                  all of the other terms and conditions of this Agreement.
                  Cellnet shall endeavor in good faith to install the
                  necessary MCCs and other infrastructure necessary to
                  enable Cellnet to read these MoNat Manual Area Meters
                  through the Fixed Network as soon as is financially
                  practicable.

         (g)      Disaster Recovery. Cellnet shall maintain a current
                  -----------------
                  disaster recovery plan for the primary NOC that at a
                  minimum provides for recovery of all systems necessary to
                  deliver the AMR Services within two (2) days of the
                  declaration by Cellnet of a disaster at the primary NOC.
                  Such plan shall include the activities that establish the
                  AMR Services at a separate disaster recovery NOC facility,
                  including, but not limited to, declaration of a disaster
                  at the primary NOC, mobilization of staff for operation at
                  the disaster recovery NOC, primary vendor notification and
                  acquisition of the necessary computer hardware, retrieval
                  of the tape back up Meter Database from off site,
                  installing and configuring the hardware and NOC Software,
                  recovery of Laclede Data from tape backup, reestablishing
                  telecommunications links for Laclede retrieval of data and
                  system testing. Cellnet shall make this plan available to
                  Laclede within ten (10) days after the Effective Date, and
                  from time to time thereafter upon Laclede's request,
                  together with evidence that Cellnet tests such plan
                  periodically in accordance with industry standards and the
                  results of the most recent such test. Additionally,
                  Cellnet and Laclede shall work together to develop, and
                  revise as necessary, procedures that will apply in the
                  event that a disaster occurs at the primary NOC. A
                  disaster shall be declared at the NOC when an event occurs
                  that results in Cellnet not being able to deliver Fixed
                  Network Data for a period of time exceeding forty-eight (48)
                  hours. Subject to the time requirements set forth in the
                  first sentence of this Section 2.2(g), upon the occurrence
                  of a disaster, Cellnet shall place a priority status on
                  restoration of the AMR Services that is at least equal to,
                  if not higher than, any other Cellnet customer within the
                  Fixed Network Area

                  Meter on Routes that have been activated pursuant to Section
                  2.1(g), for each meter that Laclede installs that is already
                  equipped with a MIU, provided Laclede successfully receives a
                  monthly automated Actual Read from Cellnet during the
                  respective Billing Window for each such meter, and for each
                  meter that Laclede receives a manual read from Cellnet (the
                  "Fee"). The Per Read Fee shall consist of the components
                  set forth on Exhibit 8. The number of days in a Billing
                               ---------
                  Window may not be decreased during the Term without the
                  prior written agreement of Cellnet. Except as set forth on
                  Exhibit 8, Laclede shall have no obligation to pay any

                  Asset Fee as set forth on Exhibit 8 ("Asset Fee") shall
                                            ---------
                  also commence for non-Activated Meters where MIU
                  installation is handled pursuant to Section 2.1(c)(iii) on
                  the earlier of the 120th day after delivery of the
                  assembled meter or MIU to Laclede or the 120th day after
                  passage of title of the assembled meter or MIU to Laclede
                  or its bank or other lender. Laclede may deduct from the
                  Fee prior to payment that amount of any penalty being
                  assessed against Cellnet pursuant to Section 2.2(d) above.
                  The Fee shall be payable via check or electronic transfer
                  at such place designated by Cellnet.

                  (i)      Within five (5) Business Days after the end of
                           each calendar month, Cellnet shall submit to
                           Laclede (directed to the Laclede AMR program
                           manager or such other individual or department
                           specified by Laclede in writing) an invoice
                           specifying the Fee due from Laclede for such
                           calendar month. The invoice shall include (A) the
                           number of automated Actual Reads received via the
                           Fixed Network during such calendar month, (B) the
                           number of Cellnet Manual Reads (categorized by
                           reading method) during such calendar month, (C)
                           the amount due and owing for the meter data
                           provided from the Fixed Network during that
                           month, (D) any reduction for the Reliability
                           Penalty calculated pursuant to Section 2.2(d),
                           and (E) the Asset Fees for such calendar month.
                           The invoice shall include any such other
                           documentation as Laclede may reasonably request.

                  (ii)     Within thirty (30) calendar days after receipt of
                           an invoice submitted by Cellnet in accordance
                           with this Agreement, Laclede shall pay Cellnet
                           the amount invoiced. If Laclede disputes any
                           invoiced amount, Laclede shall so notify Cellnet
                           in writing within fifteen (15) calendar days
                           after receipt of the invoice and give full
                           reasons for the dispute. The Parties shall act in
                           good faith to settle such dispute within five (5)
                           Business Days after Laclede provides such notice
                           of dispute to Cellnet. If the Parties are not
                           able to resolve such dispute prior to the due
                           date of the invoice, then

The information below marked by * and [] has been omitted pursuant to a request
for confidential treatment. The omitted portion has been separately filed
with the Commission.

                           Laclede shall be entitled to withhold one-half
                           (1/2) of the disputed sum and shall pay the other
                           one-half (1/2) to Cellnet at the time the
                           undisputed portion of the invoice is due.

                  (iii)    If Laclede disputes any invoiced amount, the
                           provisions of Article 19 shall apply. Following
                           resolution of the dispute: (A) any amount
                           withheld by Laclede and agreed or determined to
                           be payable shall be paid by Laclede within ten
                           (10) Business Days after such agreement or
                           determination; and (B) any amount paid by Laclede
                           and agreed or determined not to be payable shall
                           be deducted by Laclede from the amount of the
                           monthly invoice next due after such agreement or
                           determination.

                  (iv)     Should Laclede fail to make payment on or before
                           the due date of any sum due and owing (other than
                           any sum which is the subject of a bona fide
                           dispute and any Reliability Penalty), interest on
                           the amount unpaid shall accrue from the date such
                           amount was due until the date of payment at a
                           rate per annum during such period equal to the
                           prime rate set forth in the Wall Street Journal
                           most recently published on the date such payment
                           was due plus one percent (1%). Interest shall
                           also accrue at such rate on the amount withheld
                           pursuant to Section 2.3(a)(ii) (or paid by
                           Laclede pending resolution of the dispute) until
                           the time of payment if it is ultimately
                           determined that such amount was due and payable
                           to Cellnet (or, in the case of payment of an
                           amount pursuant to Section 2.3(a)(ii) which was
                           not ultimately payable to Cellnet, refund of such
                           amount to Laclede).

         (b)      Minimum Per Read Fee. The pricing in this Agreement is
                  --------------------
                  predicated upon a minimum installed base of [*******]
                  MIUs. In the event that [*******] MIUs are not installed
                  within twenty-four (24) months after the Effective Date,
                  despite Cellnet's good faith efforts and compliance in all
                  material respects with its obligations under this
                  Agreement, then, from and after such twenty-four (24)
                  month period, Cellnet shall have the right to invoice
                  Laclede, and Laclede shall pay, monthly, in addition to
                  the Fee, an amount equal to the Per Read Fee multiplied by
                  the difference between [*******] and the actual number of
                  MIUs that are installed on Laclede Gas Meters as of the
                  last day of the then current billing period. As soon as
                  more than [*******] MIUs have been installed on Laclede
                  Gas Meters, Laclede shall no longer owe such additional
                  amount to Cellnet.

         (c)      Access to Premises. Laclede hereby grants to Cellnet, its
                  ------------------
                  employees, agents and subcontractors the right of
                  reasonable access to any Laclede Gas Meter, Fixed Network
                  Meter and any other relevant assets and premises owned by
                  it or in its control where such access is necessary in
                  order for Cellnet to perform the AMR Services. Laclede
                  shall, at its own expense, take all reasonable steps to
                  obtain, in favor of Cellnet, its employees, agents and
                  subcontractors all rights of reasonable access to all
                  premises that are reasonably required to enable them to
                  perform the AMR Services and other obligations under this
                  Agreement. Cellnet shall not be in default under this
                  Agreement if it is prevented from performing due to its

                                     17

                  inability to access a meter or premises; provided Cellnet
                  or the MIU Installer has attempted to gain access to the
                  meter on six (6) separate occasions as more specifically
                  described in Section 2.1(c)(ii)(A) hereof. Nothing herein
                  shall prohibit Laclede from establishing reasonable
                  restrictions on such access and rendering of services.

         (d)      Use of Laclede Facilities. Laclede will allow Cellnet the
                  -------------------------
                  use of Laclede buildings, towers, land, transmission and
                  distribution system locations for the positioning of the
                  MCCs. Cellnet and Laclede shall jointly identify the
                  relevant sites. Notwithstanding the foregoing, Laclede has
                  the right to refuse the use of individual sites or to
                  impose reasonable restrictions on Cellnet entry to such
                  sites. Cellnet shall not compensate Laclede for the use of
                  its property as described above; provided, that Cellnet
                  shall reimburse Laclede for out-of-pocket expenses
                  incurred by Laclede due to Cellnet's use of such
                  properties.

         (e)      Multiple Index Large Industrial and Commercial Meters. If
                  -----------------------------------------------------
                  the multiple index meters used by Laclede require the
                  development of a special interface in order to be read
                  automatically, Cellnet and Laclede shall cooperate with
                  each other with regard to Cellnet's development of a
                  proposed price for the automated reading of these meters
                  where appropriate.

         (f)      Installation of Additional MIUs. At Laclede's request,
                  -------------------------------
                  Cellnet shall install additional MIUs after the completion
                  of the Deployment Period at a fee to be agreed upon by the
                  Parties.

         (g)      Laclede Gas Data File. Laclede will prior to completion of
                  ---------------------
                  the Initial Fixed Network Deployment Phase provide to
                  Cellnet a data file that details all Laclede Gas Data,
                  including addresses, the reading schedule and all other
                  pertinent Laclede customer information for all Laclede Gas
                  Meters within the Fixed Network Area. Laclede will update
                  this file and furnish it to Cellnet as additional Laclede
                  Gas Meters are added within the Fixed Network Area.
                  Cellnet shall not be in default under this Agreement if it
                  is prevented from performing its obligations hereunder to
                  the extent caused by an error contained in any data file,
                  including files containing Laclede Gas Data, provided to
                  Cellnet by Laclede.

         (h)      New Laclede Gas Meters. From time to time during the Term,
                  ----------------------
                  Laclede may replace Activated Meters with new Laclede Gas
                  Meters or install new Laclede
                  Gas Meters, each of which already has an installed MIU, in
                  the Fixed Network Area. In the event that Laclede replaces
                  any Activated Meter or installs a new Laclede Gas Meter,
                  it must promptly (i) provide Cellnet with the designation
                  and installation information of the removed Activated
                  Meter and/or the designation and installation information
                  of the new Laclede Gas Meter, electronically via the
                  Cellnet Standard Interface; and (ii) update the data file
                  that details all Laclede Gas Data, as more specifically
                  described in Section 2.3(g). A newly installed Laclede Gas
                  Meter shall not be deemed to be an Activated Meter until
                  Cellnet receives (a) a successful meter reading; (b) the
                  designation and installation information; and (c) the
                  Laclede Gas Data. Laclede shall bear all costs related to
                  the removal

                                     18

                  of any Activated Meters and the installation of all such
                  newly installed Laclede Gas Meters. Under no circumstance
                  shall Cellnet be responsible or have any liability related
                  to (x) Laclede's failure to properly remove any Activated
                  Meter, (y) Laclede's failure to properly install a new
                  Laclede Gas Meter, or (z) Laclede's failure to provide
                  Cellnet with accurate Laclede Gas Data or information
                  related to the new Laclede Gas Meter.

2.4      Systems Integration. Cellnet and Laclede shall each be responsible
         -------------------
         for ensuring that its own respective systems perform in the manner
         that such Party has agreed its systems will perform in the
         specifications for the AMR Services and the implementation of the
         Standard Interface Specifications.

2.5      Interface Changes or New Interface Implementation. The Parties are
         -------------------------------------------------
         not obligated to change or implement new interfaces once the
         Initial Fixed Network Deployment Phase is complete. If either Party
         decides to change, revise or create a new interface that is not in
         accordance with the Standard Interface Specifications, the Party
         shall submit a Change Order pursuant to Article 7. The Party
         requesting such change shall reimburse the other Party for the
         reasonable costs and expenses incurred by such non-requesting Party
         in connection with such change.

2.6      Exclusivity. Laclede acknowledges and agrees that Cellnet shall
         -----------
         have the exclusive right to retrieve data from the MIUs installed
         on Laclede Gas Meters pursuant to this Agreement, and Laclede shall
         not, and shall not engage another person or entity to, read,
         attempt to read or intercept signals or communications from the
         MIUs. Further, during the Term, Cellnet shall be the exclusive
         provider to Laclede of the AMR Services and any tasks or services
         substantially similar to the AMR Services within the Fixed Network
         Area.

2.7      Initial Term. The initial term of this Agreement shall begin on the
         ------------
         date first set forth above (the "Effective Date") and continue for
         fifteen (15) years ("Initial Term").

2.8      Term Extensions and Renewals. At the end of the Initial Term,
         ----------------------------
         Laclede and Cellnet may renew this Agreement upon mutually
         agreeable terms and conditions. The Parties agree to begin
         negotiations two (2) years prior to the end of the Initial Term.


                                  ARTICLE 3
                       MAINTENANCE, GROWTH AND REPAIR
                            OF THE FIXED NETWORK

3.1      Maintenance of MIUs.
         -------------------

         (a)      Subject to this Section 3.1 and Section 3.4 hereof,
                  Cellnet shall be responsible for all costs of repairing or
                  replacing non-working or failed MIUs. Cellnet shall
                  provide all support and maintenance required on the MIUs.
                  Cellnet shall provide service visits free of charge to
                  meters where the NOC fails to receive data from a Fixed
                  Network Meter unless such failure clearly indicates a
                  problem other than with the MIU or the Fixed Network.
                  Notwithstanding the foregoing, if the Parties

                                     19

                  determine that a MIU is damaged by anyone other than
                  Cellnet or the MIU Installer or is vandalized such that it
                  cannot reasonably be made to function properly, the MIU
                  will be considered to be a retired MIU and so treated
                  pursuant to the mechanism set forth in Section
                  2.1(c)(iii)(E).

         (b)      Cellnet shall provide service visits free of charge to any
                  Activated Meter upon the reasonable request of Laclede
                  when Laclede deems a MIU to be stopped, programmed
                  incorrectly by Cellnet or its subcontractor or reset and
                  has provided documented history of such readings. If, upon
                  such service visit, Cellnet discovers and documents that
                  the MIU was programmed correctly and is operating
                  properly, or if a MIU malfunction or incorrect programming
                  by Laclede or its third party vendor or subcontractor was
                  caused by (i) the Laclede Gas Meter, (ii) any Laclede
                  personnel, or (iii) vandalism, and such findings are
                  confirmed by Laclede, Cellnet shall deliver an invoice to
                  Laclede, and Laclede shall reimburse Cellnet's reasonable
                  expenses for such service visit not to exceed Fifty
                  Dollars ($50), payable within thirty (30) calendar days of
                  receipt of the invoice from Cellnet.

         (c)      If Laclede investigates a stopped meter report and
                  determines that there has been a MIU failure, has replaced
                  the MIU or battery, and delivered the MIU or battery to
                  Cellnet, and the failure is confirmed by Cellnet, Laclede
                  shall deliver an invoice to Cellnet, and Cellnet shall
                  reimburse Laclede for its reasonable expenses for such a
                  service visit not to exceed Fifty Dollars ($50), payable
                  within thirty (30) calendar days of receipt of the invoice
                  from Laclede.

         (d)      Notwithstanding the foregoing, if Cellnet cannot gain
                  access to a MIU to verify whether it is functioning
                  properly after making at least three (3) reasonable
                  attempts to access the MIU, Cellnet's obligations under
                  this Section 3.1 with respect to such MIU shall be
                  suspended until such time as Cellnet gains access on its
                  own or with the assistance of Laclede. During the period
                  that Cellnet is not able to gain access to such MIU, the
                  meter shall be deemed to be an Unavailable Meter, and
                  Cellnet shall provide Laclede (directed to the attention
                  of the Laclede AMR program manager at the address provided
                  hereafter in this Agreement) prompt written notice of any
                  MIU that appears to be malfunctioning to which Cellnet
                  cannot gain access. Upon receipt of such notice, Laclede
                  shall make reasonable efforts to assist Cellnet to gain
                  access to the MIU in question.

3.2      Meter Change Outs. Change outs of Laclede Gas Meters will occur
         -----------------
         during the Term in accordance with Laclede's standard procedures
         for meter change outs; provided that Laclede shall de-initialize
         the MIU on each meter that is removed and initialize the new MIU
         that is part of the meter that is being installed. Upon completion
         of the change out, Laclede shall provide to Cellnet the information
         required by the Standard Interface Specifications. Upon receipt of
         the meter change out files via the Cellnet Standard Interface,
         Cellnet shall update the NOC to allow for proper acceptance of
         transmissions from the new MIU.

                                     20

3.3      Battery Replacement. The MIU batteries will be replaced by Cellnet
         -------------------
         so that there is no interruption in the AMR Services due to battery
         failure. Cellnet shall be responsible for the cost of the battery
         and installing the battery. Any system-wide replacement of
         batteries shall be coordinated in advance with Laclede.

3.4      Vandalism. Cellnet will, within five (5) Business Days after the
         ---------
         discovery of vandalism to a MIU, repair or replace the MIU,
         provided the meter is an Accessible Meter, and Laclede will be
         responsible for Cellnet's service visit in accordance with Section
         3.1(b). Vandalism to a MIU requiring repair or replacement of the
         MIU shall be considered to be a Force Majeure Event and shall
         relieve Cellnet of its responsibilities relating to obtaining reads
         under this Agreement with respect to such MIU; provided that
         Cellnet promptly repairs or replaces such MIU upon discovery of
         such vandalism. Notwithstanding the foregoing, if Cellnet discovers
         that only the meter or both the meter and the MIU have been
         damaged, Cellnet will promptly notify Laclede of such damage in
         writing. Within seven (7) Business Days after receiving such
         written notice, Laclede shall, at its own expense, replace the
         damaged meter with a meter equipped with a MIU or remove such meter
         and disconnect gas service, provided such meter is accessible to
         Laclede. All vandalized MIUs that are replaced with a new MIU shall
         be retired in accordance with Section 3.1(a) of this Agreement.

                                  ARTICLE 4
                 INTELLECTUAL PROPERTY, LICENSES AND USE OF
                            INTELLECTUAL PROPERTY

4.1      Intellectual Property. Notwithstanding any other provision in this
         ---------------------
         Agreement to the contrary, (i) all Intellectual Property rights in
         the Fixed Network, the NOC, the Programming Software, the MIUs, the
         MCCs and the method of providing the AMR Services (the "Cellnet
         Intellectual Property") shall at all times remain the property of
         Cellnet, and nothing in this Agreement shall serve to pass
         ownership in any part of the Cellnet Intellectual Property to
         Laclede or any third party, and (ii) any developments,
         improvements, modifications, enhancements and/or adaptations of any
         kind created or developed by Laclede or by Cellnet, or jointly by
         the Parties, to any element or part of the Cellnet Intellectual
         Property shall at all times remain the property of Cellnet, and
         nothing in this Agreement shall serve to pass ownership in any part
         of the Cellnet Intellectual Property to Laclede or any third party.
         To the extent Cellnet updates or modifies the Programming Software
         for its other customers, Cellnet shall offer the same updates
         and/or modifications to Laclede at the same or lesser charge as it
         offers the same to other customers. Notwithstanding the foregoing,
         Cellnet shall provide to Laclede without charge any updates or
         modifications to the Programming Software that are required in
         order for Cellnet to perform and Laclede to utilize the AMR
         Services as contemplated under this Agreement.

4.2      License to the Programming Software. Subject to the terms and
         -----------------------------------
         conditions of this Agreement, Cellnet shall grant Laclede pursuant
         to a license agreement in the form attached hereto as Exhibit 9 a
                                                               ---------
         non-transferable, non-exclusive, limited license to use the
         Programming Software solely to program the MIUs for use on Laclede
         Gas Meters. Should Laclede require the use of the Programming
         Software beyond the expiration or

                                     21

         termination of this Agreement and provided that Cellnet continues
         to support such software, Laclede shall have the right to enter
         into an appropriate license with Cellnet for such software in
         exchange for payment of a commercially reasonable royalty by
         Laclede.

4.3      Rights in Fixed Network. Cellnet shall hold all rights to the Fixed
         -----------------------
         Network, and Laclede shall have no right or interest in any part of
         the Fixed Network, except as expressly provided under this
         Agreement.

4.4      Assignments by Laclede. All developments, improvements,
         ----------------------
         modifications, enhancements and/or adaptations to the Cellnet
         Intellectual Property created or developed by Cellnet, by Laclede,
         or jointly by the Parties shall be considered to be Cellnet
         Intellectual Property. If by operation of law any such Intellectual
         Property is not owned in its entirety by Cellnet automatically upon
         creation or development, then Laclede agrees to transfer and
         assign, and hereby transfers and assigns, to Cellnet the entire
         right, title and interest, if any, throughout the world in and to
         all such Intellectual Property, including any Intellectual Property
         rights in same, and shall cooperate with Cellnet in obtaining for
         Cellnet's benefit, and at Cellnet's sole expense, appropriate legal
         protection for such Intellectual Property, including, but not
         limited to, testifying in any legal proceedings, signing all lawful
         papers, making all rightful oaths and executing applications,
         assignments and other instruments, all at Cellnet's sole expense.

4.5      Assignments by Cellnet. All Intellectual Property that is owned by
         ----------------------
         Laclede, including, without limitation, Laclede Gas Data, the Fixed
         Network Data, and documentation and reports produced by Laclede in
         connection with the AMR Services (except to the extent such
         documentation and reports incorporate Cellnet Intellectual Property
         or Confidential Information), will belong exclusively to Laclede.
         If by operation of law any such Intellectual Property is not owned
         in its entirety by Laclede automatically upon creation or
         development, then Cellnet agrees to transfer and assign, and hereby
         transfers and assigns to Laclede the entire right, title and
         interest, if any, throughout the world in and to all such
         Intellectual Property, including copyrights in same, and shall
         cooperate with Laclede in obtaining for Laclede's benefit, and at
         Laclede's expense, appropriate legal protection of such
         Intellectual Property transferred and assigned, and to be
         transferred and assigned, hereunder to Laclede, including but not
         limited to testifying in any legal proceedings, signing all lawful
         papers, making all rightful oaths and executing all applications,
         assignments and other instruments, all at Laclede's sole expense.

                                  ARTICLE 5
                          OWNERSHIP OF INFORMATION

5.1      Ownership by Laclede. All Fixed Network Data, any documentation or
         --------------------
         reports of any kind produced by Cellnet utilizing Laclede's
         customer data or readings or any other information provided in any
         form by Laclede or Laclede's customers to, or obtained from Laclede
         Gas Meters by, Cellnet in connection with this Agreement are, and
         shall continue to be, owned solely by Laclede, and Laclede shall
         comply with all reasonable requests by Cellnet for access to all
         such data, documentation, reports and other information to the
         extent required for Cellnet to perform its obligations under this
         Agreement. Cellnet may use extracts or summaries of the Fixed
         Network Data only for its internal purposes and

                                     22

         for the purpose of promoting the sale of its services to others as
         long as such extracts or summaries do not contain any information
         identifiable to Laclede or to any particular customer of Laclede.

                                  ARTICLE 6
                                  TRAINING

6.1      Training Plan. Within twenty (20) Business Days after the date of
         -------------
         this Agreement, Cellnet shall provide to Laclede a written plan
         describing the training that Cellnet shall provide to Laclede
         personnel (the "Training Plan"). Such plan shall be subject to
         Laclede's approval, which shall not be unreasonably withheld or
         delayed. Unless otherwise approved by Laclede, all training shall
         be conducted in St. Louis at facilities owned by Laclede. All
         training shall be conducted at times and places mutually agreeable
         to the Parties. Cellnet will provide sufficient training on MIU
         installation, such that Laclede can train the trainers. The
         Training Plan will also include instruction on accessing Fixed
         Network Data via the Internet. In the event that training is not
         conducted at a Laclede facility, or is conducted outside of the St.
         Louis area, Laclede shall bear the costs and expenses related to
         such training.

                                  ARTICLE 7
                                CHANGE ORDERS

7.1      Changes. The Parties may mutually agree to modify the scope of the
         -------
         AMR Services at any time during the Term (a "Change"). If, however,
         such modifications would require the Party not requesting the
         Change to provide services materially different from the AMR
         Services specified in this Agreement, or materially extend or
         shorten the time needed to complete the AMR Services (a "Material
         Change"), the Parties shall follow the Change Order Procedure set
         forth in Section 7.2 below.

7.2      Change Order Procedure.
         ----------------------

         (a)      To request a Material Change, a Party (the "Requesting
                  Party") shall submit to the other Party (the "Responding
                  Party") a written request describing the change that such
                  Party desires ("Change Order"). The Responding Party shall
                  respond to the Change Order within fifteen (15) Business
                  Days of receipt with a written statement (i) offering to
                  perform the AMR Services in a manner consistent with the
                  Change Order, (ii) offering to perform the Change Order
                  but proposing modifications to it, or (iii) rejecting the
                  Change Order. If the Responding Party responds in
                  accordance with either (i) or (ii) in the preceding
                  sentence, the Responding Party shall include detailed
                  information as to the availability of the Responding
                  Party's personnel and resources to perform the Change
                  Order and the impact, if any, on timing of the completion
                  of the affected AMR Services or the additional or reduced
                  cost of the AMR Services. The Responding Party will use
                  commercially reasonable efforts to minimize any adverse
                  impact on the AMR Services created by the Change Order or
                  any increase in cost or expense that is to be imposed on
                  the Requesting Party. This process will continue until the
                  Parties agree in writing upon the changes to be made, the
                  impact on the timing of the

                                     23

                  completion of the affected AMR Services and any additional
                  costs or expenses associated therewith. If the Requesting
                  Party desires to implement the Change Order, it will
                  notify the Responding Party so in writing and the
                  Responding Party will promptly proceed with the
                  implementation of the applicable changes, as mutually
                  agreed upon by the Parties.

         (b)      For any Change Order, Laclede shall pay Cellnet the
                  additional charges, costs and expense agreed upon by the
                  Parties pursuant to the terms of Section 2.3(a). If the
                  Change Order results in a reduction in the anticipated
                  charges, costs or expenses, Laclede shall receive a credit
                  for such reduction against the fees otherwise owed by
                  Laclede under this Agreement.

                                  ARTICLE 8
                                SUBCONTRACTS

8.1      Subcontracts. Cellnet anticipates entering into certain contracts
         ------------
         for equipment and services, including, without limitation,
         installation of MIUs and installation and maintenance of MCCs.
         Laclede shall have the right to approve the parties with whom
         Cellnet contracts for the installation of MIUs as set forth in
         Section 2.1(d)(i). Laclede has provided to Cellnet general
         guidelines for subcontractors to assist Cellnet to select
         subcontractors that will be acceptable to Laclede. No
         subcontracting or delegation of duties by Cellnet to third parties
         shall relieve Cellnet of any obligations of Cellnet under this
         Agreement.

                                  ARTICLE 9
                               CONFIDENTIALITY

9.1      Confidential Information. "Confidential Information" means any
         ------------------------
         information or data disclosed in writing or orally by a Party (the
         "Disclosing Party") to the other Party (the "Recipient") under or
         in contemplation of this Agreement, whether delivered or obtained
         before or after the date hereof, and which (a) if in tangible form
         or other media that can be converted to readable form, is clearly
         marked as proprietary, confidential, or private on disclosure; or
         (b) if oral or visual, is identified as proprietary, confidential
         or private on disclosure and is summarized in writing so marked and
         delivered within thirty (30) days following such disclosure; or (c)
         the Recipient, considering the method of disclosure or discovery
         and the subject matter being disclosed or discovered, should
         reasonably conclude is considered confidential by the Disclosing
         Party. "Disclosing Party" and "Recipient" include each Party's
         Affiliates that disclose or receive Confidential Information. The
         rights and obligations of the Parties shall therefore also inure to
         such Affiliates and may be directly enforced by or against such
         Affiliates. For purposes of clarification, Laclede Gas Data and
         Fixed Network Data shall be deemed Confidential Information of
         Laclede.

9.2      Use of Confidential Information. The Recipient acknowledges the
         -------------------------------
         economic value of the Disclosing Party's Confidential Information.
         The Recipient shall: (a) use the Confidential Information only as
         required to perform its obligations under this

                                     24

         Agreement; (b) restrict disclosure of the Confidential Information
         to employees and advisors of the Recipient and its Affiliates who
         need to know the information in order for Recipient to perform its
         obligations under this Agreement; (c) not disclose it to any other
         person or entity without the prior written consent of the
         Disclosing Party; (d) advise those employees who access the
         Confidential Information of their obligations with respect thereto;
         and (e) copy the Confidential Information only as necessary for
         those employees who are entitled to receive it, and ensure that all
         confidentiality notices are reproduced in full on such copies.

9.3      Exclusions and Exceptions. The foregoing confidentiality
         -------------------------
         obligations shall not apply to any Confidential Information that
         the Recipient can demonstrate: (a) is or becomes available to the
         public through no breach of this Agreement; (b) was previously
         known by the Recipient without any obligation to hold it in
         confidence; (c) is received from a third party free to disclose
         such information without restriction; (d) is independently
         developed by the Recipient without the use of Confidential
         Information; (e) is approved for release by written authorization
         of the Disclosing Party, but only to the extent of such
         authorization; (f) is required by PSC data request, law,
         regulation, administrative order or subpoena to be disclosed, but
         only to the extent and for the purposes of such required
         disclosure, and only if the Recipient first attempts to notify the
         Disclosing Party of the request, law, regulation, order or
         subpoena; or (g) is disclosed in response to a valid order of a
         court or other governmental body of the United States or any
         political subdivision thereof, but only to the extent of, and for
         the purposes of, such order, and only if the Recipient first
         attempts to notify the Disclosing Party of the order to permit the
         Disclosing Party to seek an appropriate protective order.

9.4      Unmarked Confidential Information. If the Disclosing Party
         ---------------------------------
         inadvertently fails to mark as proprietary, confidential or private
         information for which it desires confidential treatment, it shall
         so inform the Recipient. The Recipient thereupon shall return the
         unmarked information to the Disclosing Party and the Disclosing
         Party shall substitute properly marked information. Nothing in this
         paragraph shall relieve Recipient of its obligations to protect
         Confidential Information that contains no restrictive marking that
         the Recipient, considering the method of disclosure or discovery
         and the subject matter being disclosed or discovered, should
         reasonably conclude is considered confidential by the Disclosing
         Party.

9.5      Ownership of Confidential Information. Confidential Information,
         -------------------------------------
         including permitted copies, shall be deemed the property of the
         Disclosing Party. The Recipient shall, within thirty (30) days of a
         written request by the Disclosing Party, return all Confidential
         Information (or any designated portion thereof), including all
         written copies or electronic data containing the Confidential
         Information, to the Disclosing Party or, if so directed by the
         Disclosing Party, destroy all such Confidential Information. The
         Recipient shall also, within fifteen (15) days of a written request
         by the Disclosing Party, certify in writing that it has satisfied
         its obligations under this Agreement.

9.6      Specific Performance. The Parties agree that an impending or
         --------------------
         existing violation of this Article 9 would cause the Disclosing
         Party irreparable injury for which it would have no adequate remedy
         at law, and agree that the Disclosing Party shall be entitled to
         obtain

                                     25

         immediate injunctive relief prohibiting such violation, in addition
         to any other rights and remedies available to it.

9.7      Survival and Severability. All obligations undertaken respecting
         -------------------------
         Confidential Information shall survive the expiration or earlier
         termination of this Agreement and shall continue for five (5) years
         from the date of the expiration or earlier termination of this
         Agreement.

         -----------------------------------------
         represents and warrants the following to Laclede:

         (a)      Duly Authorized. Cellnet is a corporation duly organized
                  ---------------
                  and existing and is in good standing under the laws of
                  Delaware. Cellnet's execution, delivery and performance of

10.2     Representations and Warranties of Laclede. Laclede hereby
         -----------------------------------------
         represents and warrants to Cellnet:

         (a)      Duly Authorized. Laclede is a corporation duly
                  ---------------
                  incorporated and existing in good standing under the laws
                  of Missouri. Laclede's execution, delivery and performance
                  of this Agreement has been duly authorized by all
                  appropriate corporate action on the part of Laclede, and
                  this Agreement constitutes the valid and binding
                  obligation of Laclede and is enforceable against Laclede
                  in accordance with its terms.

         (b)      No Conflict. Neither the execution and delivery of this
                  -----------
                  Agreement nor any assignments or licenses made hereunder
                  will conflict with or violate any other license,
                  instrument, contract, agreement, or other commitment or
                  arrangement to which Laclede is bound.

         (c)      Ownership. Laclede has and will continue to have: (i) good
                  ---------
                  and clear title or (ii) valid and enforceable rights or
                  licenses to the Laclede Gas Meters and the Laclede gas
                  systems. Laclede will not subject any MIUs installed on
                  Laclede Gas Meters to any encumbrances, liens, mortgages,
                  securities or other defects in title.

                                     27

         (d)      Consents. Except as specifically provided otherwise
                  --------
                  herein, no approval, authorization, consent, permission,
                  waiver, notice, filing or recording is necessary for
                  Laclede's execution of this Agreement.

         (e)      Non-Infringement. To the best of Laclede's knowledge and
                  ----------------
                  belief, neither Laclede's gas system nor any information,
                  data, data processes or designs supplied by Laclede that
                  will be integrated with the AMR Services infringes any
                  patents, copyrights, trade secrets or other proprietary
                  rights of any third party to the extent that said
                  infringement is based solely on said Laclede's gas system,
                  information, data, processes or designs, and Laclede has
                  no reason to believe that any such infringement or claims
                  thereof could be made by third parties. Laclede makes no
                  representation or warranty with respect to infringement
                  claims arising from AMR Services, or any system,
                  apparatus, equipment, component, method, process,
                  information, data or design provided by Cellnet hereunder.

         (f)      Compliance with Laws. Laclede shall comply with all
                  --------------------
                  applicable federal, state and local laws, regulations,
                  ordinances, and governmental restrictions in performing
                  its obligations under this Agreement.

10.3     DISCLAIMER OF WARRANTY. EXCEPT FOR THE WARRANTIES SET FORTH IN THIS
         ----------------------
         AGREEMENT, NEITHER PARTY MAKES ANY OTHER WARRANTIES, EXPRESS OR
         IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS

11.1     Termination.
         -----------

         (a)      Termination by Either Party for Breach. Either Party may
                  --------------------------------------
                  terminate this Agreement in the event of a material breach
                  of this Agreement by the other Party, provided that the
                  breaching Party has not cured such material breach within
                  forty-five (45) Business Days after the date that the
                  Party seeking termination provides written notice of such
                  material breach to the breaching Party. Such notice shall
                  set forth the full details of the breach and state that
                  the failure to cure such breach may result in termination.
                  Either Party may terminate this Agreement if there exists
                  a series of non-material or persistent breaches by the
                  other Party, that, in the aggregate, have a material and
                  significant adverse impact on the non-breaching Party;
                  provided that the non-breaching Party provides the
                  breaching Party with prior written notice of its belief
                  that such series of non-material breaches have had, are
                  having, or are reasonably likely to have a material and
                  significant adverse impact on the non-breaching Party and
                  further provided that the non-breaching Party provides the
                  breaching Party with forty-five (45) Business Days, during
                  which such non-material breaches must be cured.

         (b)      Termination by Cellnet for Nonpayment. Cellnet may
                  -------------------------------------
                  terminate this Agreement in the event that Laclede, during
                  two (2) consecutive months or three (3) or more times
                  during any Contract Year, fails to pay any invoice for the
                  Fees when due, provided that Laclede has not cured any
                  such payment default within twenty (20) Business Days
                  after the date that Cellnet provides written notice to
                  Laclede of such payment default.

         (c)      Termination for MIU System Failure. It shall be deemed to
                  ----------------------------------
                  be a material breach of this Agreement by Cellnet, for
                  purposes of Section 11.1(a), if more than [***]
                  percent ([*]%) of either the first [*****] or
                  [******] MIUs installed on Activated Meters fail to
                  provide daily automated meter reads on an average basis
                  over the total number of calendar days of the first full
                  calendar month following the installation of such
                  [*****] or [******] MIUs, respectively, and such
                  failure is not cured during the following forty five (45)
                  Business Days. In the event of such a material breach by
                  Cellnet, Laclede may avail itself of the remedies
                  contained in this Article 11.

         (d)      Termination for Insolvency. Either Party may terminate
                  --------------------------
                  this Agreement on written notice to the other if the other
                  Party becomes an Insolvent Entity. In the event of the
                  bankruptcy of Cellnet pursuant to the Bankruptcy Code and
                  an attendant rejection of this Agreement or any license or
                  assignment granted hereunder pursuant to Section 365
                  thereof, the Parties intend that the provisions of the
                  Bankruptcy Code shall apply.

         (e)      Suspension of Performance. In addition to the foregoing,
                  -------------------------
                  after expiration of the applicable cure period described
                  in Section 11.1(a) or 11.1(b) above, a non-defaulting
                  Party may, without terminating this Agreement, suspend
                  performance of its obligations under this Agreement for
                  such period of time as the non-defaulting Party deems
                  appropriate in its sole discretion to give the defaulting
                  Party an additional opportunity to cure. The
                  non-defaulting Party may terminate this Agreement at any
                  time during such suspension by providing thirty (30)
                  Business Days written notice to the other Party.

11.2     Impaired Performance. If either Party fails to materially perform
         --------------------
         or observe any of its obligations set forth in this Agreement and
         fails to take corrective action within forty-five (45) Business
         Days after written notice by the other, the non-breaching Party
         may, as an alternative to its right to terminate this Agreement,
         accept such Party's impaired performance and recover its actual
         damages.

11.3     Effect of Termination.
         ---------------------

         (a)      Removal of MIUs. Unless otherwise agreed by the Parties,
                  ---------------
                  if this Agreement is terminated as a result of breach,
                  then in the event of a Laclede breach, Laclede shall be
                  responsible for the cost of removal of the MIUs installed
                  on Laclede property. In the event of a Cellnet breach,
                  Cellnet shall be responsible for the commercially
                  reasonable cost of removal of the MIUs; provided that if
                  the removal occurs in connection with deployment of any
                  replacement system, then

                                     29

                  Cellnet shall be responsible only for the commercially
                  reasonable incremental cost of removing the MIUs; and
                  further provided that if Laclede is not deploying a
                  replacement system and the removal is at the discretion of
                  Laclede and not required by any regulatory or governmental
                  authority, applicable law or the superior rights of a
                  third party, then Laclede shall be responsible for the
                  commercially reasonable cost of removal of the MIUs. If
                  this Agreement is terminated as a result of the default of
                  Laclede, then any removal of the MIUs shall have no impact
                  on Laclede's obligation to pay any Asset Fees (as
                  specified in Exhibit 8 hereto) related to such
                               ---------
                  MIUs unless and to the extent that any such MIUs are
                  returned to Cellnet by Laclede and redeployed by Cellnet.
                  If this Agreement is terminated as a result of the default
                  of Cellnet and Laclede does not continue to utilize the
                  Fixed Network, then Laclede's obligation to pay any Asset
                  Fees related to the MIUs shall cease; provided, that if
                  Laclede continues to utilize the Fixed Network, Laclede's
                  obligation to pay the Asset Fee shall continue only for
                  those MIUs that continue to function properly and deliver
                  automated meter reads to Laclede. In all events, Laclede's
                  obligation to pay any Asset Fee shall cease on the
                  fifteenth (15th) anniversary of the Effective Date. Upon
                  expiration of the Term or earlier termination of this
                  Agreement for breach by Laclede, Cellnet may, but shall
                  not be obligated to, remove the MIUs installed on Laclede
                  Gas Meters, at Cellnet's sole cost and expense.
                  Notwithstanding the foregoing, if Cellnet desires to
                  remove the MIUs installed on the Laclede Gas Meters upon
                  the termination of this Agreement, Cellnet shall notify
                  Laclede in writing within thirty (30) days after such
                  termination, and Cellnet and Laclede shall devise a
                  schedule and methodology for such removal that is
                  reasonably acceptable to both Parties.

         (b)      Return of Confidential Information, Trade Secrets and
                  -----------------------------------------------------
                  Cellnet Property. Upon the termination of this Agreement
                  ----------------
                  by either Party for any reason, each Party shall return to
                  the other any Confidential Information of the other Party
                  in its possession or, with the consent of the Disclosing
                  Party, shall destroy the same and certify such destruction
                  to the Disclosing Party. Additionally, upon the
                  termination of this Agreement, Laclede shall return to
                  Cellnet the handheld units provided during the Initial
                  Fixed Network Deployment Phase.

         (c)      Survival of Rights and Licenses. Upon termination of this
                  -------------------------------
                  Agreement by either Party, all rights and licenses granted
                  hereunder, except for those necessary to perform
                  Transition Services as specified in Section 11.3(d) below
                  or as specified elsewhere in this Agreement, shall
                  terminate.

         (d)      Transition Services.
                  -------------------

                  (i)      Transition Services. Upon expiration or earlier
                           -------------------
                           termination of this Agreement (except due to the
                           termination by Cellnet pursuant to Section
                           11.1(a) or (b)), the Parties agree they will

                           At any time after Cellnet becomes aware of any

                           assessment penalty or fee is a result of
                           Cellnet's failure to provide AMR Services in

         (c)      Procedures. In connection with any claim for

                  indemnification, the Party seeking indemnification
                  ("indemnitee") shall give prompt notice to the Party
                  providing indemnification under this Section 12.1
                  ("indemnitor") of the assertion of any claim, or the
                  commencement of any suit, action or proceeding in respect of
                  which indemnity may be sought under this Article 12; provided
                  that the failure to give such notice shall not affect the
                  rights of such indemnitee except and only to the extent the
                  indemnitor is prejudiced by such failure. In the event
                  that any third party claim covered by this Article 12 is
                  asserted, and the indemnitee notifies the indemnitor in
                  accordance with this Section 12.1(c), the indemnitor will
                  be entitled to participate therein and assume control of
                  the defense thereof by notice to the indemnitee. The
                  indemnitee may participate in the defense of such third
                  party claim at its own expense. The indemnitee shall
                  cooperate with the indemnitor in such defense. The
                  indemnitor shall not be liable for any settlement of any
                  claim, action or proceeding which is effected without the
                  prior consent of the indemnitor, which consent shall not
                  be unreasonably withheld. The indemnitor shall not settle
                  any claim, action, or proceeding covered by this Article
                  12 in a manner which adversely affects the business
                  operations of the indemnitee without the prior consent of
                  the indemnitee, which consent shall not be unreasonably
                  withheld.

                                 ASSIGNMENT

16.1     Assignment. This Agreement will be binding on the Parties and their
         ----------
         respective successors and permitted assigns. Except as provided in
         this Section 16.1, neither Party may, or will have the power to,
         assign this Agreement without the prior written consent of the
         other, which consent shall not be unreasonably withheld or delayed,
         except that either Party may assign its rights and obligations
         under this Agreement to an Affiliate that expressly assumes such
         Party's obligations and responsibilities hereunder, without the
         approval of the other Party. Anything herein to the contrary
         notwithstanding, Cellnet may assign this Agreement and its rights
         hereunder as collateral security to lenders to Cellnet or their
         successors and assigns. The assigning Party shall remain fully
         liable for, and shall not be relieved from the full performance of,
         all obligations under this Agreement. Any attempted assignment that
         does not comply with the terms of this Section 16.1 shall be null
         and void. If a Party assigns its rights or obligations to an
         Affiliate in accordance with this Agreement, such Party shall
         promptly provide written notice thereof to the other Party.

                                AUDIT RIGHTS

17.1     Books and Records. Each Party shall have the right to inspect and
         -----------------
         audit or have audited the books and records of the other Party
         relating to the amounts invoiced hereunder and the monies owed
         hereunder for the purpose of verifying the amounts due and payable
         hereunder, upon at least ten (10) Business Days notice to the
         audited Party. Such audit may cover up to, but no more than, the
         two (2) calendar years immediately preceding the date of the audit.
         The cost of such audit shall normally be at the requesting Party's
         expense; provided, however, that the audited Party will bear the
         cost of the audit if the audit reveals, in the case of Laclede, any
         overpayment, and in the case of Cellnet, any underpayment, greater
         than two percent (2%) of the amount that was actually due for any
         twelve-month period. Such audit shall be conducted with a minimum
         of disruption to the audited Party's daily operations and during
         normal business hours. The requesting Party shall not audit the
         audited Party more than once during any twelve-month period during
         the Term.

17.2     Subcontracting, Training and Safety. Laclede shall have the right
         -----------------------------------
         to audit Cellnet's compliance with the obligations set forth in
         Section 2.1(d) of this Agreement for the purpose of verifying that
         Cellnet is fully complying with all of its obligations with regard

                                     35

         to subcontracting, training and safety. Cellnet shall cooperate
         with Laclede during the course of such an audit and make all
         applicable documentation and materials available to Laclede within
         ten (10) Business Days of Laclede's request. Cellnet shall allow
         Laclede to perform field audits to the extent Laclede deems
         reasonably necessary to confirm Cellnet's compliance with Section
         2.1(d). Provided Laclede has not found Cellnet to be out of
         compliance with the obligations of Section 2.1(d) during the
         immediately preceding twenty-four (24) months, Laclede shall not
         audit Cellnet's compliance regarding subcontracting, training or
         safety more than once during any twelve-month period during the
         Term.

                  such amount and in such form, and containing such
                  provisions, as shall protect both Laclede and Cellnet from

                  judgments of any actual or alleged agents or employees of

                  demands, suits, actions, causes of action and judgments of

18.4     Policy Provisions. All of the aforesaid insurance shall include
         -----------------
         Laclede as an additional insured (excluding the coverage described
         in Section 18.2), be endorsed to be primary and without right of
         contribution from any insurance that Laclede may have in effect and
         be written by one or more insurance companies that is or are (i)
         licensed and authorized to do business in the State of Missouri,
         and (ii) rated A - VIII or higher by A.M. Best Company. All
         policies shall contain a provision that the insurance company will
         provide Laclede with written notice of any cancellation of, or
         modification to, the policy. The consent of Laclede to the amount
         of insurance specified shall not be considered as a limitation of
         Cellnet's liability under this Agreement nor an agreement by
         Laclede to assume liability in excess of said amount or for risks
         not insured against. Cellnet shall provide proof of the
         above-described insurance to Laclede annually on or before the
         first day of each Contract Year.

18.5     Periodic Review of Policy Limits. On or about the fifth (5th) and
         --------------------------------
         tenth (10th) anniversaries of the Effective Date, Cellnet and
         Laclede shall review and discuss the continuing adequacy of the
         limits of the various insurance policies required by this Article
         18. In connection with this review, the parties shall consider,
         among other things, whether the policy limits are adequate in light
         of actual loss experience and/or whether the limits are equal to,
         or greater than, limits that are ordinary and customary in the
         automated meter reading industry. To the extent the limits are
         determined to be inadequate based on either of these factors, or
         any other factors deemed relevant in the reasonable judgment of the
         parties, Cellnet shall increase such policy limits accordingly;
         provided that Cellnet shall be required to obtain such increased
         coverage only to the

                                     37

         extent it is available on commercially reasonable terms. In no
         event shall the limits of the policies be reduced.

                             DISPUTE RESOLUTION

19.1     Dispute Procedure.
         -----------------

         (a)      Any dispute between the Parties either with respect to the
                  interpretation of any provision of this Agreement or with
                  respect to the performance by Cellnet or by Laclede
                  hereunder shall be resolved as specified in this Section
                  19.1.

         (b)      Upon the written request of either Party to the other
                  Party ("Written Request"), a dispute shall be discussed by
                  the Parties. The Parties shall meet as often as necessary
                  to gather and furnish to each Party all information with
                  respect to the matter at issue that is appropriate and
                  germane in connection with its resolution. The Parties
                  shall discuss the problem and negotiate in good faith in
                  an effort to resolve the dispute without the necessity of
                  any formal proceeding relating thereto.

         (c)      If the dispute is not resolved within thirty (30) days
                  after the date of the Written Request, then the dispute
                  shall be escalated to a Vice President of Laclede and the
                  Chief Operating Officer of Cellnet for their review within
                  forty-five (45) days after the date of the Written
                  Request.

         (d)      If the dispute is not resolved as described in (c) above
                  within sixty (60) days after the date of the Written
                  Request, the dispute will be referred to mandatory
                  mediation with the American Arbitration Association
                  ("AAA") or other organization mutually agreeable to the
                  Parties, at a mutually agreed location in St. Louis,
                  Missouri. The Parties will agree upon the selection of a
                  particular mediator as soon as reasonably practical, but
                  failing such agreement within thirty (30) days after the
                  issue is referred for mediation, the mediator will be
                  selected by AAA. Any mediator so selected shall have
                  substantial experience in the area of information
                  technology infrastructure outsourcing and the energy
                  industry.

         (e)      With the exception of applications to courts of competent
                  jurisdiction for injunctive relief or any dispute relating
                  to intellectual property rights, the Parties stipulate
                  that the submission of disputes to mediation as provided
                  in this Section 19.1, and mediation pursuant thereto,
                  shall be a condition precedent to any suit, action or
                  proceeding instituted in any court or before any
                  administrative tribunal with respect to such dispute. The
                  mediation provisions hereof shall, with respect to any
                  dispute arising out of this Agreement, survive the
                  termination or expiration of this Agreement.

         (f)      The Parties shall use reasonable effort to set the date of
                  the mediation within sixty (60) days after selection of
                  the mediator but in no event shall the mediation be set

                                     38


                  more than ninety (90) days after selection of the
                  mediator. Each Party shall bear its own mediation costs
                  and expenses and all other costs and expenses of the
                  mediation shall be divided equally between the Parties.

         (g)      Notwithstanding any other provision of this Section 19.1,
                  either Party may resort to court action for injunctive
                  relief at any time if the dispute relates to intellectual
                  property rights or the dispute resolution processes set
                  forth in this Section 19.1 would permit or cause
                  irreparable injury to such Party or any third party
                  claiming against such Party, due to delay arising out of
                  the dispute resolution process.

19.2     Continued Performance. So long as Laclede continues to pay Cellnet
         ---------------------
         the Fees for the AMR Services in accordance with the terms of this
         Agreement, the Parties agree to continue performing their
         respective obligations under this Agreement while the dispute is
         being resolved, unless and until such obligations are terminated or
         expire in accordance with the provisions of this Agreement.

                             GENERAL PROVISIONS

20.1     Cooperation by Cellnet and Laclede. Both Cellnet and Laclede shall
         ----------------------------------

         the PSC and/or Office of Public Counsel (OPC), or other regulatory

         Agreement and provide any written information that may be requested
         by these agencies in connection with these meetings or otherwise;
         and (b) demonstrate the technology that is the subject of this
         Agreement to the PSC and/or OPC or other regulatory agency;
         provided, however, that after the Deployment Deadline, Cellnet
         shall not, without its consent, be required to spend more than
         twenty (20) hours per annum performing these services.

         neither Party to this Agreement shall solicit or otherwise seek to
         hire, whether as an employee or consultant, any persons employed by
         the other Party. Notwithstanding the foregoing, either Party shall
         have the right to hire as an employee or consultant any such person
         who approaches such Party for employment or who responds to a
         general advertisement soliciting employees.

20.4     Governing Law. This Agreement and any and all claims and disputes
         -------------
         arising out of or in connection with or related to the
         relationships and arrangements between Laclede and Cellnet
         described in this Agreement shall be governed by and construed in
         accordance with the laws of the State of Missouri, without regard
         to its conflict of law principles. The prevailing Party in any suit
         brought to enforce or interpret this Agreement shall be

                                     39

         entitled to recover its reasonable attorney's fees and related
         disbursements in addition to any other relief awarded.

20.5     Publicity. Within four (4) days after the Effective Date, the
         ---------
         Parties shall prepare and release a mutually acceptable press
         release announcing this Agreement and/or the Parties' contemplated
         business relationship. As an obligation of this Agreement, each
         Party agrees that it will not, without the prior written consent of
         the other in each instance: (i) use the name, trade name,
         trademark, trade device, service mark, logo, symbol or any
         abbreviation, contraction or simulation thereof, owned by the other
         Party (the "Marks") in any advertising, marketing, promotional
         materials, publicity, press release, references, internet posting
         or otherwise, or (ii) represent, directly or indirectly, that any
         product or service offered by any Party has been approved or

         expiration or other termination of this Agreement.

20.6     Entire Agreement. This Agreement and the Exhibits referenced herein
         ----------------
         constitute the entire agreement of the Parties with regard to the
         services and matters addressed therein, and all prior agreements,
         letters, proposals, discussions and other documents regarding the
         services and the matters addressed in the Agreement are superseded
         and merged into this Agreement. Amendments and modifications to
         this Agreement may not be made orally, but shall only be made by a
         written document signed by an authorized representative of each
         Party. Any terms and conditions varying from this Agreement on
         any order or written notification from either Party shall not be
         effective or binding on the other Party.

20.7     Force Majeure. Neither Party shall be liable for any default or
         -------------
         delay in the performance of its obligations hereunder if and to the
         extent and while such default or delay is caused, directly or
         indirectly, by a Force Majeure Event. If a Force Majeure Event
         occurs, the non-performing Party will be excused from any further
         performance or observance of the obligation(s) so affected for as
         long as such circumstances prevail and such Party continues to use
         commercially reasonable efforts to recommence performance or
         observance whenever and to whatever extent possible without delay.
         Any Party so delayed in its performance will immediately notify the
         other by telephone and describe at a reasonable level of detail the
         circumstances causing such delay (to be confirmed in writing within
         twenty-four (24) hours after the inception of such delay). If any
         delay on the part of either Party resulting from a Force Majeure
         Event exceeds sixty (60) days, the other Party shall have the right
         to terminate this Agreement on notice to the delayed Party.

20.8     Waiver. No waiver of any breach of any provision of this Agreement
         ------
         shall constitute a waiver of any prior, concurrent or subsequent
         breach of the same or any other provisions hereof.

20.9     Severability. If any provision of this Agreement shall be held to
         ------------
         be invalid, illegal or unenforceable, the validity, legality and
         enforceability of the remaining provisions shall not in any way be
         affected or impaired thereby, and such provision shall be deemed to
         be restated to reflect the Parties' original intentions as nearly
         as possible in accordance with applicable law(s).

                                     40


20.10    Counterparts. This Agreement may be executed in counterparts. Each
         ------------

3.6        Siva Kolappa      02/11/02          o    In the sample read file layout, fixed the order of reads to mimic the
                                                    order of reads as they appear in read file, switched off peak to on peak
                                                    and vice versa to comply with Cellnet standards, added more description
                                                    to the read type section, rectified minor errors.
                                               o    Revamped the retrofit file layout to include more verbiage.
                                               o    For most interfaces, added specific instructions about what value
                                                    will be stored in the meter_id field for water meters.
                                               o    In the customer information file layout, modified description to the
                                                    install_time filed to remove time.
                                               o    In the post install file for gas and electric meters, rectified the
                                                    data type for the field_collect_1 field.
                                               o    In DBM interface section, added verbiage on the type of for water meters in
                                                    response to a post install record.
                                               o    Included reject file philosophy
                                               o    Modified meter_electronic field in the customer information file layout
                                                    to include DRR notification for "to be DRR" accounts.
-------------------------------------------------------------------------------------------------------------------------------
3.7        Siva Kolappa      8/1/02            o    Calibration File - Added 3 custom fields
-------------------------------------------------------------------------------------------------------------------------------
3.8        Joy Varghese      05/28/04          o    Added lp_frequency field to the customer interface file format for
                                                    database maint
                                               o    Modified the device type to T from X, in the Restoration Verification
                                                    file formats. Also added the new device_power_status RO
                                                    in the response file layout section.

3.0 TYPES OF INTERFACES


FILE TRANSFER INTERFACE (FTI):
------------------------------

File transfer is the only supported mode of data transfer between Cellnet
and the utility. Cellnet provides "read and write" privileges to the utility
on the UNIX server that houses the OCDB. The utility will be able to write
files into the OCDB server, receive files from the OCDB server and delete
files that have been picked up. The utility will be required to initiate an
FTP (File transfer Protocol) connection to pick-up or post files in the OCDB
server.

The following section describes the file transfer protocol that needs to be
followed when Cellnet sends or receives ASCII flat files to or from its
utility customers. This protocol is currently used for all existing programs
where data delivery is done in the form of ASCII flat files.

3.1 FILE NAMING CONVENTION

Each file interface will have a unique name. This unique file name will be a
"constant" and will not vary every day. If a file name needs to be changed,
the utility needs to coordinate this with Cellnet. All agreed upon file
names are stored within the OCDB database.

For example, if meter.reads is the agreed upon file name for the "Monthly
Meter Reads" interface, the file that will be created by Cellnet will be
called meter.reads.

3.2 FILE CREATION MODE

All files created by either Cellnet or the Utility will be created in
"Append" mode. This means that, for a particular interface, if the Utility
does not pick up a file created by Cellnet the previous day, Cellnet will
append today's information, to the bottom of the file that was created the
previous day. The net result is, the file will have two days worth of data.
The same applies to the files created by the Utility.

3.3 FILE CREATION CHECK

For each file created by both Cellnet and Utility, after the file creation
is complete, a zero byte file should be created to convey the completion of
the data file creation. For example, if the data file is called
"METER.READS", the zero-byte file will be called "METER_READS.OK"

The naming convention for this zero-byte file is the name of the data file
with a ". OK" extension. This file will be referred to as the "TRIGGER FILE"
in the following sections.

<PAGE>


3.4 FILE EXCHANGE FREQUENCY

The frequency of data file exchange could be configured to suit the
utility's processing schedule. For example, utility may want to set up all
interfaces to run all seven days in a week or it would prefer to create
files only during week days.

3.5 FILE PUSH & PULL

The utility, for all interfaces, will either push files into the OCDB server
or pull files from OCDB server.

3.6 FTP USER & FILE ARCHIVING

An FTP user will be created in the OCDB server that houses the oracle
database. The Utility will use this FTP user to connect to the OCDB server.
This connection will take the utility to the following directory -

/u05/home/celldba/utility/Utility_Acronym/prod
Where UTILITY_ACRONYM is a value used to denote a particular utility.

EVERY PRODUCTION FILE RECEIVED FROM THE UTILITY OR CREATED BY CELLNET FOR
THE UTILITY IS ARCHIVED WITH A DATE EXTENSION IN THE FOLLOWING DIRECTORY -

/u05/home/celldba/utility/Utility_Acronym/prod/history
Where UTILITY_ACRONYM is a value used to denote a particular utility.

3.7 FTP IMPLEMENTATION


The following section is a step-by-step instruction on how the ftp
philosophy should be implemented. It is divided into two sections -

5.0 REJECT FILE PHILOSOPHY

The following reject file philosophy applies to all data interfaces, where
in the file creator is Cellnet and the file receptor is the utility.

It is possible for the utilities to reject records in the data files created
by Cellnet, when a record in the file fails to meet a business rule
validation done by the utility or when any given record in the file has
invalid data in it. In such cases, the utility can create a reject file with
all rejected records. This reject file in addition to having the reject
record will also have the reject reason appended to the end of each record.

The format of the reject file is the complete data record that was rejected,
appended with the reject reason. The reject reason should not be longer than
                                 -------------------------------------------
80 characters in length. For example, if the data record is 100 bytes long,
-----------------------
the reject record will be a total of 180 bytes long, where in, the first 100
bytes is the rejected data record and the last 80 bytes will contain the
reject reason.

The utility should always create the reject files in an "append" mode. This
is to ensure that a pre existing reject file does not get overwritten. The
"ok" file philosophy mentioned in the previous section does not apply to
reject file creation.

5.0 INTERFACES


5.1. ROUTE REQUEST

Creator                    : Cellnet
Input/Trigger              : Cellnet route table with the scheduled routes
Output File Name           : route.req
Timing                     : TBD
Error File Name            : route.req.rej (Created by Utility)
Timing                     : TBD
Frequency                  : Daily (7 Days/Week)

Based on the overall rollout plan, Cellnet schedules the routes via the
route-planning tool. Two Cellnet working days prior to the actual changeout
day, Cellnet needs current information on the route in order to perform the
actual installations. The routes that are scheduled for changeout two days
later (identified by `RC') and the routes that are scheduled to be changed
30 (thirty) calendar days in the future (identified by `MR') are processed
by this job and records are inserted into the file. For routes that are
requested for changeout (RC), this action also signifies the beginning of
                              -------------------------------------------
database maintenance. In other words, once a route has been requested for
--------------------
changeout, database maintenance begins from the utility to Cellnet for all
the meters in the requested routes, irrespective of whether the meter is an
AMR meter or not.

The MR request can be used by the utility for customer notification
purposes. The program (Cellnet Program Manager) may choose to receive or not
receive a response to the MR route request. Depending upon the program
manager's decision, the utility needs to or not respond to the MR route
request.

NOTE - UTILITY SHOULD SEND DATABASE MAINTENANCE OR DATABASE SYNC RECORDS
ONLY FOR ROUTES THAT HAVE BEEN REQUESTED AS RC. IF THE UTILITY SENDS RECORDS
FOR ROUTES THAT HAVE NOT BEEN REQUESTED, SUCH RECORDS WILL BE REJECTED AND
WILL END UP AS AN EXCEPTION.

A file will be created by Cellnet with the relevant information (refer to
the file layout). The utility processes this file and will return a set of
pre-installation service order records, if the route request is valid. If
the request is invalid, then the utility will respond with a reject file
with all invalid route requests.

5.2. CUSTOMER INFORMATION FILE LAYOUT

The customer information file layout shown below encompasses multiple
interfaces. This file layout defines the layout for the following interfaces -

-  PRE INSTALL
-  PLANNING DUMP
-  DATABASE MAINTENANCE
-  DATABASE SYNCHRONIZATION



5.2.1 PRE INSTALL

Creator           : Utility
Input/Trigger     : Route request
File Name         : pre.install.rc
Timing            : TBD
Error File Name   : pre.install.rc.rej (Created by Cellnet)
Timing            : TBD
Frequency         : Daily (7 Days / Week)


The utility passes pre-install information on every meter in the routes that
were requested in the RC interface. This includes meters that Cellnet may
not be responsible for installing. For example, even if the utility is
changing out polyphase meters with the standard utility process, those
meters should still be sent in this interface. This interface serves as a
driver for the install process and as an initial load of Cellnet's operating
database. Based on the operating agreements between Cellnet and the utility,
both parties may be responsible for installing a subset of the meters on the
route. Accordingly, each record passes through a filter that determines
whether the meter will be changed out using the Cellnet process.

-  The records in the file should be sorted in route/read sequence order.
-  If a meter is an AMR ready meter, the cellnet_meter flag in the interface
   should be marked accordingly.

5.2.2 PLANNING DUMP

Creator           : Utility
Input/Trigger     : Manual request from Cellnet
File Name         : planning
Timing            : TBD
Error File Name   : planning.rej (Created by Cellnet)
Timing            : TBD
Frequency         : Approximately every 4-6 months

As the name indicates the planning dump is used to plan and schedule routes
for changeout. The two fields that play a crucial role are the "route_id"
and the "billing_cycle" field. These two fields are used to create "route"
records and are mandatory for the route-planning tool to work. The planning
dump is basically a file with all meters in the contract area, wherein each
meter records has customer information, meter information and the meters
physical location. The RF engineering group from Cellnet also uses this
planning dump, for LAN-WAN planning purposes. Hence the address information
should also be present for all meters in the file.


5.2.3 DATABASE MAINTENANCE

Creator       : Utility
Input         : Changes to the DBM specific fields in the utility's CIS system.
File Name     : dbmaint
Timing        : TBD
Error File    : dbmaint.rej
Timing        : TBD
Frequency     : Daily (7 Days / Week)

The database maintenance interface is used to keep the utility database and
OCDB in sync with each other. This synchronizing process is crucial for the
successful installation of meters; meter reads delivery and the ongoing
operation of the systems. This interface supports a master - slave
relationship between utility databases and OCDB. Any changes to either
system are first applied to the master, the utility systems, and then to the
slave, OCDB. The utility will initiate changes to OCDB by generating 3 kinds
of transactions -

ADD (A)    - For adding new meters to OCDB
DELETE (D) - To delete a meter from OCDB
CHANGE (C) - To update meter or customer information, for a meter existing
             in OCDB

This interface is also used by the utility to exercise the features
available on the Cellnet system. For instance, this interface will enable
the utility to change the type of metering for an account or to set a
logical disconnect threshold, etc.

For the layout for the Database Maintenance interface, please refer to the
                                                       -------------------
Customer Information file layout. It is important that the transactions
--------------------------------
applied to the utility's database are also applied to OCDB in a timely
manner. Typically, this file is created each night and will capture all
changes applied to the utility's systems that day.

The transactions in any single DBM file must be sorted by transaction type.
DELETE transactions are sent first, followed by ADD transactions, followed
by CHANGE transactions. On any given day, if there is a DELETE transaction
for a meter, there should not be any CHANGE transaction in the same file for
that meter, unless there is also an ADD transaction for that meter.

Transactions are only sent for meters on routes that have gone through the
route changeout request (RC) process. Transactions are sent for both AMR and
Non-AMR meters.

If any record cannot be loaded into the OCDB due to data format errors or
due to invalid data being present in the file, such error records will be
moved to a reject file. The OCDB database analyst will then contact the
utility operations group for resolving these issues.

The meter identifier programmed into the transmitting module is the primary
key in OCDB. OCDB will not allow duplicate meter identifier values to be
stored. Hence, for every DBM transaction, the utility must pass the meter
identifier. In addition to the meter identifier, OCDB uses a field referred
to as "utility_id", as the secondary key before processing any DBM
transaction. The utility_id can have any value that will provide a
reasonably unique reference to an account or meter. Normally, it is either
the customer account number or the socket identifier or a combination of the
premise identifier and the service point. Hence for every DBM transaction to
be processed, the meter_id and the utility_id passed by the utility should
match the values in OCDB. If there is no match, such transactions will be
rejected. If the utility_id itself needs to be changed, the utility must
send a CHANGE transaction with the old utility_id value in the UTILITY_ID
field and the new utility_id value in the NEW_UTILITY_ID field.

There are three types of DBM transactions -

       -  ADD
     When a new meter is installed on a requested route, utility must send
     an ADD transaction for the new meter. All DBM fields mentioned in the
     file layout are required.
       -  DELETE
     When a meter in a requested route is removed, the utility must send a
     DELETE transaction. A minimum of Meter ID, Utility Id and the
     transaction_type (D) should be passed in the file.
       -  CHANGE
     When one of the DBM specific fields changes in the utility's CIS
     system, utility must send a CHANGE transaction. If any one of DBM
     specific field changes, all other DBM specific fields must also be
     passed in the file, regardless of whether the reminder of the fields
     has changed.

FOR A GAS METER, IF THE CHANGEOUT INVOLVES ONLY A MODULE RETROFIT, UTILITY
---------------
MUST SEND A CHANGE TRANSACTION WITH THE CELLNET_METER FIELD SET TO `Y'. IN
THE POST INSTALL FILE, UTILITY CAN COMPARE THE OLD METER IDENTIFIER AND THE
NEW METER IDENTIFIER FIELDS TO DETERMINE IF THE CHANGEOUT INVOLVED ONLY A
MODULE RETROFIT. IF IT IS NOT A MODULE RETROFIT, EVERY POST INSTALL RECORD
FROM CELLNET MUST RESULT IN A DELETE TRANSACTION FOR THE OLD METER AND AN
ADD TRANSACTION FOR THE NEW METER.

FOR A WATER METER, FOR EVERY RECORD IN POST INSTALL FILE, THE UTILITY HAS TO
-----------------
RESPOND WITH A DELETE TRANSACTION FOR OLD METER AND AN ADD TRANSACTION FOR
THE NEW METER. THERE ARE TWO POSSIBLE SCENARIOS - 1. "FIELD RETROFIT
SCENARIO", WHERE A WATER METER IS RETROFITTED WITH A MODULE IN THE FIELD. 2.
"METER EXCHANGE SCENARIO", WHERE THE OLD WATER METER IS REPLACED WITH A NEW
WATER METER RETROFITTED WITH A MODULE. IN BOTH THE SCENARIOS, THE UTILITY
HAS TO RESPOND WITH A DELETE TRANSACTION FOR THE OLD METER AND AN ADD
TRANSACTION FOR THE NEW METER.

SCENARIOS TRIGGERRING A DBM TRANSACTION
---------------------------------------

1)  House burned down - DELETE
2)  New House comes up in a new/old location - ADD
3)  Empty House for a long time. Utility decides to remove the meter, as no
    one would be reading the meter for a long time. - DELETE
4)  House whose meter was removed previously (as in case 3) gets a new
    meter - ADD
5)  Change to the following fields are identified as crucial by Cellnet -

    o   Cellnet_Meter - This is marked as `Y' if the meter is CellNet
        -------------
        AMR meter. This field is very crucial because the DBM process
        in OCDB treats an AMR meter very differently than a Non-AMR meter.
    o   Demand_Reset - If the utility bills a customer on the first of
        ------------
        every month, and the customer moves out on the 10 of the
        month, the utility may want to reset the demand peak when a
        new customer moves in. This field should be populated only
        when the utility desires to reset the demand for a demand
        meter. Otherwise this field should be a blank. Also, demand
        reset cannot be done on a date specified by the utility.
    o   Meter_Id - Any changes to the meter id would be a DELETE for the
        --------
        old meter and an ADD for the new meter.
    o   Utility_Id -. If the utility_id needs to be changed, the utility
        ----------
        must send a CHANGE transaction with the old utility_id value in
        the UTILITY_ID field and the new utility_id value in the
        NEW_UTILITY_ID field.
    o   Demand_Interval and Demand_Sub_Interval - These values
        ---------------------------------------
        describe the type of demand metering provided for this meter.
        If the value for both fields is the same, the Cellnet system
        will calculate "Block Demand" as opposed to a "Rolling
        Demand". Any changes to these values should trigger a CHANGE
        transaction.
    o   Load_Profile - This field indicates whether interval data
        ------------
        should be collected for this meter. Any change should trigger
        a CHANGE transaction.
    o   Load_Profile_Interval - This value indicates the size of the
        ---------------------
        load profile interval. Any change in this value should trigger
        a CHANGE transaction.
    o   Tou_Rate - This value indicates the TOU rate if this customer
        --------
        is on time-of-use metering. Any change in this value should
        trigger a CHANGE transaction.
    o   Logical_Disconnect - This value indicates whether the customer
        ------------------
        is on logical disconnect. Any change in this value should
        trigger a CHANGE transaction.
    o   Cum_Threshold and Dem_Threshold - These values are used in
        -------------------------------
        conjunction with the logical disconnect flag and sets the
        amount of consumption per day. Any change in these values
        should trigger a CHANGE transaction.
    o   Usage_status - This value indicates whether the utility
        ------------
        believes there should be usage on this meter. This value is
        used by Cellnet to determine whether a meter with zero usage
        should be checked for malfunction. Any change in this value
        should trigger a CHANGE transaction.

----------------------------------------------------------------------

    o   Power_Status - This value indicates whether the utility
        ------------
        believes the meter is powered. For instance, if the power to
        the meter were cut at the pole, this value must be set to `N'.
        If the meter is powered, it is set to `Y'. Cellnet uses this
        field to determine whether a meter module that stops
        transmitting should be checked for malfunction. Any change in
        this value should trigger a CHANGE transaction. This field is
        crucial because, most reports that monitor the performance of
        meters rely on this field very heavily.
    o   Route_Id - This value indicates which route a meter belongs
        --------
        to. Any change in this value should trigger a CHANGE
        transaction. A meter in a route that is not Cellnet's
        responsibility should not be re-routed to a route which is
        Cellnet's responsibility. This will directly impact the
        performance metrics managed by Cellnet.
    o   Life_Support - This field indicates whether a customer is a
        ------------
        "medical alert" customer. Any change in this value should
        trigger a CHANGE transaction.

7)  Meter Changeout initiated by utility system and completed by utility
    processes - DELETE for old meter, ADD for new meter
8)  Meter changeout by Cellnet, sent to utility via post install interface -
    DELETE for old meter, ADD for new meter.
9)  Module Field Retrofit on a gas or water meter (No Meter Change) either by
    utility or Cellnet - CHANGE transaction with Cellnet_Meter field set to `Y'.
10) Module removed from a gas or water meter and not replaced with another
    module (No Meter Change) either by utility or Cellnet - CHANGE
    transaction with Cellnet_Meter field set to `N'.
11) Service to the Customer changes from a single phase meter to a 3 phase
    meter - DELETE for OLD meter, ADD for new meter.
12) Temporary Service Meters - Assume a construction site and the
    installation of temporary meter for construction purposes and then it
    is removed and taken to another temporary site down the block. Utility
    should send a DELETE for the old location and an ADD for the new
    location. In this case, the sequence of transactions is important,
    since the database maintenance process will not allow a meter to be in
    two places at the same time. If the ADD for the new site comes before
    the DELETE transaction, the ADD transaction will fail.

5.2.4 DATABASE SYNCHRONIZATION

Creator           : Utility
Input/Trigger     : Manual request from Cellnet
File Name         : dbsync
Timing            : TBD
Error File Name   : dbsync.rej (created by Cellnet)
Timing            : TBD
Frequency         : Approximately every 4-6 months

While the database maintenance interface will update OCDB with all
meter/customer data changes happening in the CIS system for accounts that
have been requested by Cellnet, exceptions on either side will cause certain
accounts to stay out of sync. Over a period of time, the utility database
and Cellnet database has a potential to drift apart. The database
synchronization process basically helps the two databases get back in sync.

The utility, based on Cellnet request, will produce a single file with all
REQUESTED accounts. The information on these accounts overwrites the
information in OCDB. The following rules apply to the sync process -

       - The transaction type should be set to `A' as in ADD for all accounts
         in the sync file.
       - The sync process will not process any records with duplicate meter
         identifier, referred to as meter_id in OCDB terminology.
       - No database maintenance records should be processed in OCDB, while
         a sync is being performed.

5.3. POST INSTALLATION SERVICE ORDER

Creator       : Cellnet
Input         : Changeout information from RIMS
File Name     : post.install.eg (for electric and gas), post.install.water
                (for water meters)
Timing        : TBD
Error File    : post.install.eg.rej, post.install.water.rej (Created by utility)
Timing        : TBD
Frequency     : 7 Days a week

Each day, Cellnet sends a post installation file to the utility, indicating
the meter changeouts that have been completed. Depending on the timing of
the file creation, it will contain meter changeouts either from today or the
previous working day or a combination of both. The closing meter reads
reported in the file have already been verified by the cross-dock. The meter
installer records the closing read from the meter while in the field, and a
person in the cross-dock independently reads the meter.

When the utility processes the file, any records that fail validation can be
reported in the reject file. Closing reads outside a high/low check or an
exception with the old or new meter number can cause rejects. Rejected
records must include the reason the record was rejected. Usually the reject
reason is appended to the end of the record provided by Cellnet and sent
back to Cellnet. Cellnet processes will verify the reject records sent by
the utility rectify errors if any and resend the record in the next day's
file, with the verified flag set.

If there is a case where two electric meters are being replaced by one
meter, as can be the case when a multi-function meter is installed, the post
install file will contain two records, one for each of the two removed
meters. The socket in which the new Cellnet meter is fitted shall have a
post-install record, which includes the new meter identifier while the
record for the other meter will have a new meter identifier of all blanks.

Data from probed electric meters is not handled through this process. Probed
electric meters can either be handled completely through the utility
process, or the Cellnet process can be used except for obtaining the probed
data from the old meter or recorder. In the latter case, the post install
record will include all readings that are obtained from the face of the
meter. The installer could have a utility handheld to obtain the probed data
as a "pickup" read.

The first time the post install records are sent, they are already verified
and checked by RIMS before the data is sent to the utility. The Verified
flag will still be set to a `N' the first time. If the utility rejects the
post install record, further validation is done by retrieving the digital
image stored in the RIMS database. The record is resent with the verified
flag set to a `Y'. The utility cannot reject the records for the second
time.

Any customer specific information passed in the first 5-util_extra fields in
the Pre Install interface is returned via Post Install. Also, this interface
will provide up to 4 field-collected values, collected during the time of
installation by the installer. For example, the utility might want to
collect the "Corrosion State" of a gas or a water meter.

WATER SPECIFIC INFORMATION
--------------------------

There are three separate units involved in the changeout process of a water
meter -

DEVICE IDENTIFIER

Identifier of the actual water meter (could be the meter serial number
appended with the meter manufacturer).

MIU IDENTIFIER

This is the value that is programmed into the transmitting module as the
meter_id. The transmitting module among other things transmits a meter_id
and a module_id. For an electric or a gas meter, the meter_id value
programmed into the module is the actual meter serial number of the meter
appended to the meter manufacturer code. However, for a water meter, the
serial number of the meter that the module will be married to is unknown
until the meter has been visited. For this reason, the manufacturing factory
programs the module_id into the module_id field and the module_id pre-fixed
with zeroes into the meter_id field. For example,

Module Id = 1234567
MIU Id    = 0001234567

In the above example, note that the module_id has been prefixed with three
leading zeroes to make it ten digits long.

ENCODER IDENTIFIER

Identifier of the encoder attached to the physical meter.

POST INSTALL FILE LAYOUT FOR WATER METERS
-----------------------------------------

NOTE:
-----
1. Each Numeric column (NUMBER) should be left padded with zeroes.
2. Each Character column (CHAR) should be right padded with spaces.
3. DATE field should be in the format shown in the file layout.

M - MANDATORY
O - OPTIONAL

5.5. METER READS REPORT


Creator           : Cellnet
Input             : Utility billing requirements
File Name         : meter.reads
Timing            : TBD
Frequency         : Daily
Timing            : TBD

Each day, Cellnet's meter read collection application populates OCDB with
one meter read for each discovered meter on the network. Meters whose
scheduled consumption readings for monthly billing cycle are manually read
will also be populated in OCDB. All the reads are available to the utility
in file format described below.

This interface will support delivery of both daily meter reads and scheduled
consumption readings for monthly billing cycle. Also, if desired, Utility
can get a separate billing file and a separate daily file. A trailer record
will be created at the end for each day. This will basically be used to
signal the end of the batch and a check for the number of records received
in the batch.

Check the table on Page 21 for the different rates supported by Cellnet. The
number of records per meter in the read file will depend upon the rate the
meter is on. The table below shows the number of records per meter that will
appear in the read file, for each rate.

NOTE
----

The record format shown below for Time Of Use meters is an example of a two
                                                                        ---
period time of use meter, i.e. we have shown below a meter which is tracking
------------------------
usage across two time bins in a 24 hour period. The descriptions for each
bin are utility specific. For example, in the lay out shown below, we have
described the FIRST BIN AS OFF PEAK and the SECOND BIN AS ON PEAK. This
could vary from utility to utility. Cellnet can track up to a maximum of
four bins in a 24-hour period. The utility has the option to decide on the
naming convention of each bin.

If the read data is monthly demand peak (KW or KVAR) or daily demand peak
(KW or KVAR), then the Read Description is prefixed with `M' or `D'
respectively.

Utility can also have the on peaks, off peaks and any other bins printed in
the order they desire. In the example shown below, we are printing the on
peak followed by off peak.

 NOTE

          -   In the READ TYPE column, `B' stands for scheduled consumption
                     ---------
              reads for monthly Billing and `D' stands for Daily meter
              reads.
          -   The application can create two types of files - billing file
                                                              ------------
              and/or a daily file. In the billing file, the read type is
                       ----------
              always a `B'. However, in the daily file, it can be `D' or
              `B'. In the daily file, all reads are marked as `D', except
              for those meters whose read date (this is the billing cycle
              read date defined and stored in OCDB based on the read
              schedule) happens to be the file creation date. For such
              meters, the read type is `B'.
          -   READ DESCRIPTION column, `*' denotes the bin descriptions
              ----------------
              provided by the utility. The description is prefixed with a
              `D' or `M', denoting a MONTHLY VALUE or a DAILY VALUE,
              respectively.
          -   In the TIME STAMP column, `**' denotes that either "READ_TIME
                     ----------
              of the cumulative read" or "DAILY PEAK TIME" is provided in
              the file. It is for the utility to choose what time stamp they
              would like to see printed in the file.

5.6. CALIBRATION DATA REPORT

Creator           : Cellnet
Input             : RIMS daily retrofit processes
File Name         : calibration
Timing            : TBD
Frequency         : Daily
Error File        : calibration.rej
Timing            : TBD

Each day, Cellnet can pass the calibration information on meters (electric
meters only) that were either issued to an installer or shipped to the
utility. This calibration data is the result of the testing done during the
retrofit process of a meter. This file is created by a RIMS application and
placed in the OCDB server for the utility to pick up.

If the utility finds an invalid record in the file, such records can be
placed in a reject file and sent back to Cellnet for further verification.

Retrofit data is basically meter module marriage information, where in, the
meter_id and module_id reported are the actual values programmed into the
module. This file is created by a RIMS application and placed in the OCDB
server for the utility to pick up. This file will have retrofit data for
gas, water, and electric meters.

FOR ELECTRIC METERS, retrofit data is fed into the RIMS system from two
sources - Cellnet Retrofit Centers and Original Equipment Manufacturers
(OEM's). Usually, the utilities also receive a file directly from the OEM's
and this file contains retrofit information on meters retrofitted by the
OEM's. Hence, most utilities desire to receive retrofit data from RIMS, only
for meters retrofitted in Cellnet's Retrofit Centers. However, Cellnet can
provide retrofit data received from both sources or can selectively filter
out data from one source, depending on the utility's requirement. In the
event where data from both sources are reported, RIMS will create a single
file with data from both sources.

FOR GAS AND WATER METERS field retrofitted through RIMS, retrofit data is
reported only after the marriage information is received into RIMS from the
Hand Held.In this scenario, retrofit data is loaded into RIMS after the
installation was performed in the field.

FOR GAS AND WATER METERS, if the meter module marriage happens at the OEM,
then, RIMS will report this as soon as it receives this information from the
OEM.

FOR GAS AND WATER METERS retrofitted in the utility meter shop, retrofit
data will be reported after RIMS receives this information from the utility
meter shop.

If the utility finds an invalid record in the file, such records can be
placed in a reject file and sent back to Cellnet for further verification.
The reject file is a compilation of all rejected records, one meter per
line, with the reject reason appended to the end of the record.

Cellnet collects load profile data on the meters that are configured to
collect load profile data. Cellnet can support 5, 15, 30 and 60 minute load
profile intervals. Load profile data is wall clock aligned. Load profile
collection is a daily process, which populates data into OCDB.
Cellnet has the capability to report load profile data in two different
formats:

1. Lodestar Format to be fed into an MV90 system
2. Cellnet standard format

DATA QUALITY CODE

The following table gives the list of codes that indicate the status of data
being reported to the utility.

5.9.1 LODESTAR FORMAT LOAD PROFILE REPORT

The Lodestar report has the following features:

   -    Capability to report load profile data on a Monthly (Billing Cycle),
        Daily and Off Cycle basis (Read schedule for load profile meters should
        be the same as regular meter reads).

   -    Data will always be reported from midnight to midnight.

   -    No estimation done for missing data

   -    Missing data will be filled with zeros tagged with code `9'.

   -    For each meter reported, start time will always be `0001' Hours (one
        minute after midnight) and end time will be `2400' Hours.

   -    Data in the past can be reported for all meters on load profile. This
        can be handled when the utility requests Cellnet operations to report
        data for a specific period in the past. The request has to be initiated
        manually by the utility.

   -    The read value reported is the actual disk rotations within a given
        interval and not the dial read.

   -    For the Off Cycle read request, utility will have to send a request
        file to Cellnet. This is for meters where data is reported on a
        monthly/billing cycle basis only.

A trailer record at the end of each batch will indicate the number of
intervals that have been reported for all the meters. There will not be a
trailer record per meter. This interface will report load profile data
stored in OCDB. Unlike the Lodestar format report, this interface will not
fill in zeroes for missing data. Also, the read value reported is the actual
consumption within the load profile interval for a given meter.

5.10.  SERVICE UPGRADE REQUEST & FIX-UP REQUEST

This interface provides the utility the ability to upgrade the
service/configuration on their customers from one rate to another. To
provide reliable advanced services on Cellnet meters, a minimum "Packet
Success Rate" (PSR) is required. This interface enables the verification of
the PSR of a meter, before an upgrade of service is provided. For example,
if the utility wants to upgrade a meter from simple consumption metering to
demand metering, the utility would first check with Cellnet to see if that
particular meter has a minimum PSR (as defined by Cellnet standards) before
requesting the actual upgrade via database maintenance.

The utility sends a batch request for an upgrade of service. If Cellnet
determines that the meter has the minimum required PSR to support the
requested rate, the utility is clear to update their CIS system and then
send a database maintenance CHANGE transaction indicating the rate change.
After receiving the DBM change transaction, Cellnet will configure the
tracking MCC to start collecting the specified advanced readings for that
meter.

If the same meter did not have the minimum required PSR to support the
requested rate, the utility can request Cellnet to enhance the RF coverage
via the FIX-UP REQUEST interface. For each fix up request received from the
utility, a work order is generated and is handed over to a RF technician
from Cellnet. Once the necessary steps have been taken to boost the PSR to a
level where the PSR now meets or exceeds the minimum required PSR, the
utility is informed via the a response interface. At this point, the utility
is clear to update their CIS system and send DBM CHANGE transaction.

Both the SERVICE UPGRADE REQUEST & FIX-UP REQUEST INTERFACE share the same
file lay out. The only difference being, the value in the individual records
(request type) differentiates between these two types of requests. The
utility will get one response file back from Cellnet with responses for both
                 ---
SERVICE UPGRADE REQUESTS & FIX-UP REQUESTS.

If the utility wants Cellnet to execute all requested upgrades irrespective
of the current PSR, there is an option within OCDB to automatically generate
a Fix-up request, enhance the PSR and then respond to the utility. If this
option is selected, there will be no need to implement the Fix-up Request
interface.

5.11.  ON DEMAND READ

This interface enables the utility to obtain the most recent information for
any automated meter in the network. Cellnet's web interface "Utility Data
Link" (UDL) provides this feature. UDL also allows its users to look up 35
days of historical data for a meter, one meter at a time.

5.12. PARALLEL METER READ FOR QUALITY CHECK

Creator           : Utility
Input             : The utility's manual meter reading process
File Name         : parallel.reads
Timing            : TBD
Frequency         : daily

This interface applies only to consumption meters and serves to evaluate
Cellnet's RF coverage during the route installation. During the meter
deployment process, there is typically one read date for each route during
which reads are obtained by both the utility's manual read process and by
the Cellnet network. This is because, there is a delay between the time
Cellnet begins mass meter installation for a route and the time Cellnet
takes over responsibility for providing billing reads for that route
(typically between 60 and 90 days).

For example, if a route is billing on the first of October, and Cellnet
begins installing meters on that route on the first of September. By the
third week of September, Cellnet completes installation on the majority of
the meters, Cellnet does not take over read responsibility for that route
until 90% of the MIU's are installed.. The read around October 1 provides an
opportunity to compare manual reads and network reads. This comparison
allows Cellnet to identify suspect meters or modules on that route.

The file is created each day by the utility, and it contains the manual
meter reads that were obtained for routes that have started through the
install process but are not yet Cellnet's responsibility to read.

5.15 POWER OUTAGE REPORT

Creator           : Cellnet
File Name         : power.outages
Timing            : TBD
Frequency         : TBD (generally every 10 min)

The power outage application can detect outages on any of the three
following devices -electric meters, MCC and the Cell Master. When a power
outage occurs, the Cellnet module has enough power in it to send a LAST GASP
packet to the MCC. When the MCC gets this packet, it starts a 12-minute
timer for that meter. If the MCC gets a packet again from the same meter
before the 12 minutes expire, it resets the timer and does not report it to
the system controller.

IF the MCC does not hear from the same meter within 12 minutes, the MCC
forwards this event to the cell manager. Each cell manager has one event log
file. THE POWER OUTAGE DETECTOR DAEMON running in all cell managers searches
the event log file for Meter Last Gasp, Meter Power Up, MCC Last Gasp, MCC
Power Up, Cell Master Last Gasp and Cell Master Power Up.

If the Daemon finds any event in the event log, it forwards it to the Power
Outage Handler process running in the POA server. All events are queued
here. All such events are then recorded in OCDB in NEW status. Then, the
OCDB filter process kicks in to filter out bad outages - if meter has PSR
less than 50%(configurable) or if we did not hear from at least 2 meters
under the same transformer within 30 seconds. This ensures that we report
only good outages to the utility.

DOES NOT APPLY FOR GAS AND WATER METERS.

5.16 RESTORATION VERIFICATION


Restoration verification process works as follows:

     -    The utility decides to send a crew out to fix a problem with their
          distribution network.
     -    The crew goes out and fixes the problem, and then calls into the
          dispatch operator to indicate that the repair has been made.
     -    The dispatch operator triggers a restoration verification action.
     -    The utility "Power Outage Management System" identifies the
          devices that should have been restored as a result of the repair.
          The utility has a database that describes the relationship between
          various devices out in the field and how they are tied to each
          other. In other words, the utility knows the transformers on a
          specific circuit, and the meters that draw power from a specific
          transformer.
     -    The system sends Cellnet, queries on specific devices to find out
          if power is back on or not. This is most often at the transformer
          level, but could also be at the meter level. The query includes
          the time that the repair was made. This query is in the form of a
          file, usually with more than one request. File layout of this file
          is described in section 5.16.1.
     -    Cellnet handles the request. If the request is at the meter level,
          Cellnet does the equivalent of an on-demand read for that meter.
          If the request is at a transformer level, Cellnet looks at the
          bellwether meter to find if power is back on for all meters
          drawing power from the transformer. If the time of the last packet
          received is later than the time of the repair, it indicates that
          the restoration was successful. If not, the power may still be
          out. Part of handling the request is to ensure that we have
          allowed adequate time for the MCC to receive a packet from the
          TOMM.
     -    A bellwether meter is the meter with the highest Packet Success
          Rate for one transformer. The bellwether meter is determined on a
          weekly basis and can change from one week to another.
     -    Cellnet sends the status of the device back to the utility in the
          form of a file. The layout of the file is described in detail in
          section 5.16.2.
     -    If Cellnet receives restoration verification request for multiple
          meters that are being tracked by the same MCC, the applications
          groups them together and queries the MCC only once. This is done
          in order to optimize the network traffic.

DOES NOT APPLY FOR GAS AND WATER METERS.

5.17 PRE CONFIGURATION FOR ADVANCED METERS

This interface basically ensures that there is minimal disruption in
collection of advanced reads from advanced accounts when the utility
                                                             -------
replaces a Non AMR meter with an AMR meter. By default the Cellnet network
--------
tracks only "Cumulative Consumption" read. In a scenario where a Non AMR
meter is replaced with an AMR meter, the network starts collecting
cumulative consumption only. Normally, the network starts collecting
advanced metering data only after Cellnet receives a DBM record for the new
meter and configures the network to enable tracking of the desired advanced
read. This usually is a 2-3 day process and results in lost revenue for the
utility.

If the utility is performing installation on all or certain advanced
accounts, the utility can have Cellnet "Pre Configure" the network to track
a specific advanced rate immediately after a meter is discovered and over
the network and after the "COOK TIME **" is complete. For this, the utility
must provide a list of AMR meters that they will be installing on advanced
accounts at least 3 business days before the actual installation is done.

** COOK TIME is the time taken by the network to assign a newly discovered
meter to the MCC that hears it the best. Cook time is usually a minimum of 4
hours and can go up to 8 hour. During this period of time, only cumulative
consumption read is tracked.

DOES NOT APPLY FOR GAS AND WATER METERS.

validations, such records will be moved to the reject file.

- Meter should not already be installed in the field.
- If the rate requested is a Time of Use rate, it has to be a valid TOU rate
  defined in OCDB.
- If demand rate is requested, demand interval and subinterval should be not
  null
- If demand rate is requested, demand interval must be a multiple of demand
  subinterval
- If demand rate is requested, demand subinterval must be a multiple of the
  native interval of the module
- A retrofit record should exist for an electric meter.
- If a gas module needs to be pre configured, OCDB should have an entry
  denoting that this module was shipped to the utility.
- If load profile flag is set, lp_interval must be a multiple of the native
  interval of the module.

5.18 SYSTEM LOAD SNAPSHOT REPORT

System load snapshot is a process that will provide the utility customers
with Time of Use (TOU) information, on every AMR meter on the network that
is already not in a TOU rate, as frequently as requested by the utility. In
order to fulfill this requirement, all the AMR meters on the network,
already not in a TOU rate, have to be configured to a special TOU rate. OCDB
will not collect and store TOU data for such metes on a daily basis.
However, the MCC's in the network will be tracking and storing TOU data as
defined in the system controller. This TOU data is never passed to OCDB
during the regular read process.

The flow of process is as follows:
1.   On an extremely hot or cold day, utility requests system load snapshot
     data.
2.   A manual request is made to the local Cellnet Operations center to
     initiate a SLS reporting for a day.
3.   The system load snapshot (SLS) data collection process is triggered.
4.   This process via input parameters could collect data either for
     yesterday or for the day before, since the MCC stores snapshots for
     3 consecutive days.
5.   An internal tou_rate (156) has been established specifically for SLS.
     The time period definition of this rate will vary from utility to
     utility. This needs to be defined for every utility and the all MCC's
     configured.
6.   Data is collected and stored in OCDB.
7.   The system load snapshot interface runs automatically at the end of
     collection to create the output file.

DOES NOT APPLY FOR GAS AND WATER METERS.

5.19 OFF CYCLE READS REQUEST

Creator             : Utility
Input               : Off cycle read request from utility
File Name           : offcycle.request
Error File Name     : offcycle.request.rej (Created by Cellnet)

Output File Name    : offcycle.response
Timing              : TBD
Frequency           : Daily


In order to bill a customer, utility needs meter consumption readings at the
end of a billing cycle. But in the case where a customer moves out, the
utility would need a read on the "move out date" to bill the customer. If
the move out date happens to be between two consecutive read dates, the
utility cannot wait until the next read date to get a closing read. The off
cycle reads request interface enables the utility to request reads on an
ad-hoc basis. A read can be requested both for a future date and a past
date.

This interface requires receiving a request file from the utility with a
list of meters that need an off cycle read and the read required date.
Cellnet will process such requests, validate the requests and then respond
back with reads for valid requests.

There are three key fields in this interface -

READ REQUESTED DATE

This is the date on which OCDB received the off cycle read request from the
utility. It is important to understand that the utility could have generated
this request in their systems 2 days earlier and sent it to Cellnet after
two days. In this case, the database does not truly reflect the actual date
of creation in OCDB. Utility will have to ensure that the off cycle read
requests are provided to Cellnet as soon as they are created in their
systems. The utility will have to provide Cellnet with enough time to gather
a valid read. If the read request does not honor the agreed upon "notice
time", such requests will be rejected.

READ REQUIRED DATE

Utility needs a read with this timestamp to bill the customer. The read
provided in the response file could be either the requested time-stamp or a
time-stamp that will be considered as a valid read (as defined by the
billing window). The application has the ability to filter out and not
report any reads that fall outside the billing window.

READ REPORTED DATE

The date utility wants Cellnet to report the read back to them. Basically,
this field determines the day this off cycle read will be reported in the
file.

                        Gas Meter Compatibility List

OVERVIEW
The Gas Meter Compatibility List is the result of retrofit experience and
feedback from meter manufacturers (American Meter, Equimeter, and others).
Every attempt has been made to ensure the accuracy of the information in
this document. There may be limitations to compatibility unknown to Cellnet
due to changes made which Cellnet has been unable to document through our
research and substantial meter library. This document will evolve over time
as Cellnet and its partners expand and update their product base. Any
questions about the compatibility information contained in this document
should be forwarded to your Cellnet representative.

                                  EXHIBIT 6

                        ADJUSTMENT TO MONTHLY MIU FEE

         The Monthly MIU Fee shall be adjusted in accordance with this
Exhibit 6.

         (a) For purposes of this Exhibit 6, the following capitalized terms
have the respective meanings set forth below:

"Number of MIUs Condemned", for a given Contract Year, equals the number of
 ------------------------
Laclede Gas Meters with MIUs removed from service in such Contract Year that
Laclede is not able to reuse on other Laclede Gas Meters.

"Number of MIUs Reconditioned", for a given Contract Year, equals the number
 ----------------------------
of MIUs (of the Number of MIUs Condemned) that Cellnet is able to
recondition and reuse for other than Laclede Gas Meters in such Contract
Year. The Number of MIUs Reconditioned includes MIUs that were retired in a
previous Contract Year, held in inventory, and subsequently reconditioned
and reused.

"Net Number of MIUs Retired", for a given Contract Year, equals the Number
 --------------------------
of MIUs Condemned minus the Number of MIUs Reconditioned in such Contract
Year.

"Number of MIU Startups", for a given Contract Year, equals the number of
 ----------------------
MIUs provided by Cellnet for installation on Laclede Gas Meters in such
Contract Year, excluding the number of MIUs Cellnet is required to replace
under the terms of this Agreement.

"MIU Retirement Unit Cost", for a given Contract Year, equals the amount in
 ------------------------
the row so named for such Contract Year in the chart attached as Appendix A.
                                                                 ----------

"MIU Startup Unit Cost", for a given Contract Year, equals the amount in the
 ---------------------
row so named for such Contract Year as shown on Appendix A.
                                                ----------

"Number of Annual Reads" equals the actual number of MIU readings that were
 ----------------------
subject to the Per Read Fee in a given Contract Year.

"Total Annual Reconditioning Cost", for a given Contract Year, equals the
 --------------------------------
Number of MIUs Reconditioned multiplied by $5.

"Total Annual Retirement Cost", for a given Contract Year, equals the Net
 ----------------------------
Number of MIUs Retired multiplied by the MIU Retirement Unit Cost.

"Total Annual Startup Cost", for a given Contract Year, equals the Number of
 -------------------------
MIU Startups multiplied by the MIU Startup Unit Cost.



The information below marked by * and [] has been omitted pursuant to a request
for confidential treatment. The omitted portion has been separately filed
with the Commission.


"Total Actual Annual Cost", for a given Contract Year, equals the sum of (i)
 ------------------------
the Total Annual Reconditioning Cost for such Contract Year, (ii) the Total
Annual Retirement Cost for such Contract Year, and (iii) the Total Annual
Startup Cost for such Contract Year.

"Total Projected Annual Cost", for a given Contract Year, equals the amount
 ---------------------------
in the row "Total Projected Cost" for such Contract Year in the chart
attached as Appendix A.
            ----------

"Annual Cost Differential", for a given Contract Year, equals the difference
 ------------------------
between the Total Actual Annual Cost for such Contract Year and the Total
Projected Annual Cost for such Contract Year.

"Cumulative Actual Annual Cost" equals the sum of Total Actual Annual Costs
 -----------------------------
for Contract Years that have not been included in a calculation that
resulted in an increase or decrease in the Monthly MIU Fee pursuant to
Section (b) of this Exhibit 6.

"Cumulative Projected Annual Cost" equals the sum of Total Projected Annual
 --------------------------------
Costs for Contract Years that have not been included in a calculation that
resulted in an increase or decrease in the Monthly MIU Fee pursuant to
Section (b) of this Exhibit 6.

"Cumulative Annual Cost Differential" equals the Cumulative Actual Annual
 -----------------------------------
Cost less the Cumulative Projected Annual Cost.

"Reconditionable MIU", means a MIU that Laclede removes from a Laclede Gas
 -------------------
Meter and is not able to reuse, but for which Cellnet has indicated in
writing that it has another customer that has a gas meter or gas meters with
which such a MIU is compatible and who is willing to accept reconditioned
MIUs. Cellnet shall provide a list of meter types on which it can utilize a
Reconditionable MIU within 30 days of the execution of this Agreement and
update or confirm such list from time to time, but at least annually within
30 days after the first day of each Contract Year.

         (b) If the Cumulative Annual Cost Differential is greater than
$[*******], the Monthly MIU Fee shall be increased or decreased (as
applicable) in accordance with the procedures set forth below. If the
Cumulative Annual Cost Differential is less than or equal to $[*******],
there shall be no increase or decrease in the Monthly MIU Fee pursuant to
this Exhibit 6.

         (c) If the Cumulative Actual Annual Cost exceeds the Cumulative
Projected Annual Cost by more than $[*******], or if the Cumulative
Projected Annual Cost exceeds the Cumulative Actual Annual Cost by more than
$[*******], the Monthly MIU Fee for future reads shall be increased or
decreased, as applicable, as follows:

                  (i) First, the Cumulative Annual Cost Differential shall
be amortized over the remaining number of months of this Agreement at an
annual interest rate of [*]% to determine a monthly payment amount.
Such monthly payment amount will be multiplied by the number of months
remaining on this Agreement to determine the "Future Value of the Cumulative
                                              ------------------------------
Annual Cost Differential";
------------------------


The information below marked by * and [] has been omitted pursuant to a request
for confidential treatment. The omitted portion has been separately filed
with the Commission.


                  (ii) Second, the "Total Number of Remaining Reads" shall
                                    -------------------------------
be determined as follows. The Number of Annual Reads for the previous
Contract Year (the "Base Year") will be used as a base-line and the number
                    ---------
of reads for each subsequent Contract Year ("Number of Assumed Reads") will
                                             -----------------------
assume a [*]% increase over each immediately preceding Contract Year. For each
Contract Year, the Number of Assumed Reads for such Contract Year shall
equal the Number of Assumed Reads for the previous Contract Year multiplied
by [****]. The "Total Number of Remaining Reads" shall be (A) the sum of the
              -------------------------------
Number of Assumed Reads for each Contract Year (if any) subsequent to the
Base Year, less (B) the product of a fraction whose numerator is an amount
equal to the number of months in the first Contract Year subsequent to the
Base Year prior to implementation of the increase or decrease to the Monthly
MIU Fee and whose denominator is 12, multiplied by the Assumed Reads in such
Contract Year;

                  (iii) Third, determine the "Read Cost Differential" by
                                              ----------------------
dividing the Future Value of the Cumulative Annual Cost Differential by the
Total Number of Remaining Reads and rounding the result to tenths of a cent;
and

                  (iv) Fourth,

                           (A) If the Cumulative Actual Annual Cost exceeds
the Cumulative Projected Annual Cost by more than $[*******], the Monthly
MIU Fee for future reads shall be increased by an amount equal to the Read
Cost Differential, or

                           (B) If the Cumulative Projected Annual Cost
exceeds the Cumulative Actual Annual Cost by more than $[*******], the
Monthly MIU Fee for future reads shall be decreased by an amount equal to
the Read Cost Differential.

                           (C) In the event the Monthly MIU Fee is increased
or decreased as described above in this subsection (c)(iv), then the
cumulative cost calculation described in this Exhibit 6 is started over at
zero for the next Contract Year.

                  (v) Solely for purposes of reference, an example of the
foregoing four-step calculation is attached as Appendix B.
                                               ----------

         (d) There shall be no adjustment under this Exhibit 6 for the
first, second, or third Contract Year. The first adjustment to the Monthly
MIU Fee described in this Exhibit 6 shall be calculated at the beginning of
the fourth Contract Year (which will commence during 2008) using the third
Contract Year as the Base Year and then again for every Contract Year
thereafter, and if applicable, the Monthly MIU Fee for the next Contract
Year will be increased or decreased, as applicable, from the Monthly MIU Fee
for the Base Year, as such Monthly MIU Fee has been previously adjusted, if
applicable, in accordance with this Exhibit 6.

         (e) Notwithstanding anything contained in this Exhibit 6 or the
Agreement to the contrary, if the Cumulative Annual Cost Differential is
greater than $[*******], the Read Cost Differential shall be calculated
assuming a Cumulative Annual Cost Differential of $[*******]. The excess
Cumulative Annual Cost Differential over $[*******] shall be
paid by Laclede to Cellnet (if the Cumulative Actual Annual Cost exceeds the
Cumulative Projected Annual Cost),

<PAGE>
or by Cellnet to Laclede (if the Cumulative Projected Annual Cost exceeds
the Cumulative Actual Annual Cost) within 30 days after the final
determination of the Cumulative Annual Cost Differential.

         (f) During the term of the Agreement, not later than 30 days after
the end of each month, Laclede shall send a statement to Cellnet showing the
Number of MIUs Condemned in the previous month. Laclede shall, at its own
cost and expense, ship all Reconditionable MIUs to Cellnet's facility in
Laclede's service area.

         (g) Not later than 45 days after the first day of each Contract
Year (beginning in 2008), Cellnet shall deliver a certificate (the
"Certificate") to Laclede setting forth the adjustment to the Monthly MIU
 -----------
Fee (if any) for such Contract Year, or stating that no adjustment is
required, along with supporting calculations in reasonable detail. If,
within 30 days after delivery of the Certificate, Laclede alleges that the
Certificate has not been prepared in accordance with this Exhibit 6 or that
the Certificate contains a mathematical mistake or other error, Laclede
shall deliver to Cellnet within such period a written notice (a "Notice of
                                                                 ---------
Disagreement") specifying in reasonable detail all disputed items and the
------------
basis therefor, including reasonable detail. Subject to the rights described
in Article 17, the failure by Laclede to provide a Notice of Disagreement to
Cellnet within such 30-day period will constitute the acceptance by Laclede
of the Certificate, and in such event the calculations and other
determinations set forth in the Certificate shall be the final calculations
and other determinations for the Contract Year in question. During the
15-day period following the delivery of any Notice of Disagreement or such
longer period as Cellnet and Laclede shall mutually agree, representatives
of Cellnet and Laclede shall meet and seek in good faith to resolve in
writing any differences that Cellnet and Laclede may have with respect to
the matters specified in such Notice of Disagreement. If, at the end of such
15-day period (or such longer period as mutually agreed), Cellnet and
Laclede have not resolved such differences, the dispute shall be submitted
to the dispute resolution procedure contained in Sections 19.1(d), (e), (f)
and (g) of the Agreement.

         (h) Notwithstanding the adjustments provide for in this Exhibit 6,
the parties shall use commercially reasonable efforts to maximize the use of
reconditioned MIUs.
