access is neither successful nor expedient, and upon receipt of a service
request from DataCom, Itron will provide services as set forth in Schedule "D",
and shall dispatch appropriate employees or contract personnel to investigate
any Nonconformity. As part of its field investigation process, Itron will make
available all labor, material, exchange equipment, tools, and consumable
supplies (e.g., wire, batteries, brackets, and cables) necessary for
de-installation and re-installation of Nonconforming Covered Components, as well
as CCUs requiring battery replacement. If Itron discovers site characteristics
that adversely impact CCU performance, Itron will attempt to relocate the
affected CCU to an alternative site if



                                                                         PAGE 10
<PAGE>   14

an alternative site is available within fifty (50) yards of the original site
location. If CCU performance cannot be restored, Itron will remove the CCU from
the field and report the site(s) to DataCom as out of service. In any case,
Itron will take such action as may be necessary to eliminate the Nonconformity.

               (b) Covered Components Corrective Maintenance. Itron shall
provide corrective maintenance for Nonconforming Covered Components during
regular hours at Itron's servicing location, within the response/return times
documented in Schedule "D". Upon receiving the Covered Component at the
servicing location, Itron will complete the corrective maintenance, or arrange
for all corrective maintenance necessary, to return the Covered Component to its
original operating specifications, excluding minor cosmetic deficiencies (e.g.,
minor cracks, dents, and scratches). Itron will furnish all parts and materials
necessary to complete the corrective maintenance and eliminate any
Nonconformity. Parts furnished will be new, or in a condition equivalent to new,
and shall be functionally equivalent to those parts removed from service.
Nonconforming, malfunctioning or inoperative parts so replaced by Itron will
become Itron property.

               (c) Covered Component Installation and Maintenance. Itron will
ensure all Covered Components have been installed properly as of the Effective
Date, and subsequently if installed by or under Itron's direction pursuant to
this Agreement or the EnSite Agreement. Itron will maintain all Covered

2002, in addition to all other remedies which may be available to DataCom
hereunder, the fee payable by DataCom pursuant to Paragraph 5.2 may be reduced,
at DataCom's sole option, by up to 15% until such time as the Fixed Network
Expansion is completed. In no event shall any amount by which such fee is
reduced be recoverable by Itron.



                                                                         PAGE 11

               (c) Third Party Warranties. To the extent permitted and subject
to Paragraph 9.1, Itron will assign to DataCom, without recourse to Itron, all
third party manufacturer's warranties related to the Covered Components which
are in effect on the Effective Date. The expiration of such warranties, however,
shall not be acceptable cause for non-delivery, or unsatisfactory delivery, of
Services under this Agreement.



                                                                         PAGE 16

existence or is terminated or dissolved, liquidates or is liquidated.

                      (b) In the event that Itron breaches or fails to perform
any of its covenants, agreements or obligations under this Agreement, and such
breach or failure continues for a period of forty-five (45) days following
Itron's receipt of written notice from DataCom of such breach or failure to
perform (the "CURE PERIOD"), then for each day following such Cure Period that
the breach or failure continues, DataCom shall have the option, exercisable in
its sole discretion, to withhold and deduct from the next scheduled fee payment
under Paragraph 5.2, an amount equal to (i) the annual fee then payable under
Paragraph 5.2, divided by (ii) 365. If such breach or failure to perform
continues for a period of thirty (30) days beyond the end of the Cure Period,
then DataCom shall have the right, at its option, to terminate the Agreement
pursuant to Paragraph 7.2, and upon such termination, DataCom may exercise any
or all of the remedies in Paragraph 6.2 (in addition to any other rights and
remedies it may have at law, in equity or otherwise, including those under this
Agreement, the Purchase Agreement, the Escrow Agreement and the Radio Frequency
Sharing Agreement). If



                                                                         PAGE 28
<PAGE>   32

Itron has advised DataCom in writing that the breach or failure is not capable
of being cured within the Cure Period through the exercise of Itron's reasonable
best efforts, and provided that (x) Itron has commenced and is continuing to use
its reasonable best efforts to cure the breach or failure, and (y) DataCom is
satisfied that such reasonable best efforts will result in a timely cure, then
the Cure Period shall be extended for the additional time necessary to achieve
such cure.

        6.2    REMEDIES FOR EVENTS OF DEFAULTS

               Upon the occurrence of an Event of Default under Paragraph
6.1(a), and as permitted by Paragraph 6.1(b), DataCom shall be entitled to
exercise any or all of the following remedies in addition to any other rights
and remedies it may have, at law, in equity or otherwise, including those under
this Agreement, the Purchase Agreement, the Escrow Agreement and the Radio
Frequency Sharing Agreement:

               (a) DataCom may immediately draw down all or any portion of the
Letter of Credit required to be maintained at that time;

               (b) DataCom may cause all items held in escrow pursuant to the
Escrow Agreement to be delivered to it; and

               (c) DataCom may terminate this Agreement pursuant to Paragraph
7.2 hereof.

        6.3    CHANGE IN CONTROL

               Upon the occurrence of a Change in Control, DataCom may cause
all items held in escrow pursuant to the Escrow Agreement to be delivered to
it for its use, to the extent necessary in DataCom's sole judgement, in
connection with the Fixed Network.

SECTION 7.     TERM AND TERMINATION

               The term of this Agreement will commence on the Effective Date,
unless earlier terminated as provided elsewhere in this Agreement, and will
automatically terminate at the end of December 31, 2013 (the "TERM"); provided,
however, that the Term shall be automatically extended for an additional two
year period at the end of the Term and at the end of each subsequent two year
extension period unless either (a) Itron has given DataCom written notice of its
intent not to renew at least two years prior to the end of the Term or any
extension period or (b) DataCom has given Itron notice of its intent not to
renew at least six months prior to the end of the Term or any extension period.

include each such additional extension period.

        7.2    TERMINATION BY DATACOM

               Without limiting any other rights or remedies (including, without
limitation, any right to seek damages and other monetary relief) that DataCom
may have in law or otherwise, DataCom may terminate this Agreement (a) upon the
occurrence of an Event of Default, (b) as provided in Paragraph 6.1(b), or (c)
at any time at its convenience upon 120 days notice to Itron. In the event of
such termination for convenience, Itron shall discontinue Services hereunder in
accordance with the termination notice, effective on the date of such
termination, the Parties shall mutually agree on the procedures for termination
and DataCom shall make payment to Itron in the amount of (i) $1.0 million if the
termination notice is given on or prior to the fifth anniversary of the
Effective Date, (ii) $500,000 if the termination notice is given after the fifth
anniversary but on or prior to the tenth anniversary of the Effective Date and
(iii) $250,000 if the termination notice is given after the tenth anniversary of

all licenses and other rights necessary or appropriate to operate the Fixed
Network and Covered Components.

        7.3    TERMINATION BY ITRON

               Without limiting any other rights or remedies (including, without
limitation, any right to seek damages and other monetary relief) that Itron may
have in law or otherwise, Itron may terminate this Agreement upon written notice
if:

               (a) DataCom breaches its obligations to make payments under
Section 5 hereof, unless such failure to pay is covered by a bona fide, good
faith dispute, provided that (i) Itron sends written notice to DataCom
describing the breach, and (ii) DataCom does not cure the breach within thirty
(30) days following its receipt of such notice; or

               (b) There is an appointment of a receiver, custodian, or trustee
of DataCom for all or substantially all of the property of DataCom; DataCom
makes an assignment for the benefit of creditors other than an assignment for
security or collateral purposes in connection with a financing; DataCom convenes
a meeting of its creditors, or any class thereof, for purposes of effecting a
moratorium upon or extension or composition of its debts and thereafter is
unable to obtain an agreement with such creditors for a moratorium upon or
extension or composition of its debts; DataCom shall have been adjudicated
bankrupt or insolvent or all or substantially all of its property shall have
been sequestered by an order of federal, state, foreign or other court of
competent jurisdiction; there shall have been a filing of an involuntary
petition against DataCom seeking liquidation, reorganization, arrangement,
readjustment of its debts or for any other relief under the Bankruptcy Code or
under any other act or law pertaining to



                                                                         PAGE 30
<PAGE>   34

insolvency or debtor relief, whether state, federal or foreign, now or hereafter
existing, which petition shall not be dismissed within sixty (60) days after
such filing; DataCom has commenced any bankruptcy, reorganization or insolvency
proceeding or other proceeding under the Bankruptcy Code or under any other act
or law pertaining to existing or DataCom has consented to the taking of any of
the foregoing actions; or DataCom voluntarily dissolves or terminates its
existence or is terminated or dissolved, liquidates or is liquidated.

SECTION 8. INDEMNIFICATION

        8.1    OF DATACOM

               Itron will indemnify, hold harmless and defend DataCom, its
directors, officers, employees and agents from and against any and all losses,
damages, liabilities, claims, penalties, fines and other costs and expenses,
including reasonable attorneys' fees and costs of settlement ("LOSSES") that
DataCom reasonably incurs arising from Itron's performance of or failure to
perform any Services required to be performed by Itron under this Agreement,
including, without limitation, customer claims relating to Sentry Device
telephone line seizures. However, Itron will have no such obligation regarding
any Losses to the extent they arise from DataCom's negligence or willful
misconduct.

        8.2    OF ITRON

               DataCom will indemnify, hold harmless and defend Itron, its
directors, officers, employees and agents from and against any and all Losses
that Itron reasonably incurs from DataCom's performance or failure to perform
any obligation under this Agreement. However, DataCom will have no such
obligation regarding any Losses to the extent they arise from Itron's negligence
or willful misconduct.

        8.3    INTELLECTUAL PROPERTY INDEMNIFICATION

               Itron will indemnify, hold harmless and defend DataCom, its
directors, officers, employees and agents from and against all Losses that
DataCom reasonably incurs in connection with any third party claim that any
Covered Component, Software or Software Release provided by Itron under this
Agreement infringes or misappropriates the U.S. copyright, trade secret or
trademark rights of a third party ("INFRINGING MATERIAL"). If the use of any
Infringing Material is enjoined by a court of competent jurisdiction, Itron,
shall, at Itron's option and sole cost and expense, either (a) procure for
DataCom the right to continue use of the Infringing Material, (b) replace the
Infringing Material with material that is substantially similar in functionality
and performance, but noninfringing, (c) modify the Infringing Material to
eliminate the infringement or misappropriation, or (d) terminate the enjoined
activity with an appropriate reduction in



                                                                         PAGE 31
<PAGE>   35

the Annual Fee; provided however, that such termination and reduction shall not
excuse Itron from performance of its obligations pursuant to its Agreement.
Itron will have no liability under this Paragraph for any infringement or
misappropriation due to any repair, maintenance, service modification to or
alteration of the Fixed Network performed by any personnel other than Itron
personnel (including its employees, agents and contractors) or Itron-trained
DataCom personnel (including its employees, agents and contractors) after the
Effective Date which has not been approved by Itron as required by the terms of
this Agreement; or (ii) any combination of the Fixed Network in whole or in part
with any material or software not included in the Fixed Network which has not
been installed by Itron personnel or Itron-trained DataCom personnel and which
has not been approved by Itron as required by the terms of this Agreement.

        8.4    PROCEDURE

               In connection with any claim or action described in this Section
8, the Party seeking indemnification will (a) give the indemnifying Party prompt
written notice of the claim, (b) cooperate with the indemnifying Party (at the
indemnifying Party's expense) in connection with the defense and settlement of
the claim, and (c) permit the indemnifying Party to control the defense and
settlement of the claim, provided that the indemnifying Party must diligently
defend the claim and may not settle the claim without the indemnified Party's
prior written consent (which will not be unreasonably withheld or delayed).
Further, the indemnified Party (at its cost) may participate in the defense and
settlement of the claim.



                                                                         PAGE 32
<PAGE>   36

        8.5    PAYMENT OF INDEMNIFICATION CLAIMS

               Losses which are indemnified against hereunder shall be paid by
the Indemnifying Party within 30 days after such Party's receipt of notice of
such Losses, which notice shall include such evidence as is reasonably necessary
to establish the amount of the Losses and the Indemnifying Party's liability
therefor. If and to the extent Itron does not pay for any indemnified Losses
within such 30 day period, then, in addition to any other rights and remedies it
may have at law, in equity or otherwise, including those under the Agreement,
the Purchase Agreement, the Escrow Agreement and the Radio Frequency Sharing
Agreement, DataCom may, at its option, (a) set off the full amount of such
unpaid Losses against the next payment(s) due under Paragraphs 5.2 and/or 5.3
hereof and/or (b) draw up to the full amount of such unpaid Losses under the
Letter of Credit.

SECTION 9. LIMITATION ON LIABILITY

        9.1    DISCLAIMER

               EXCEPT AS OTHERWISE SET FORTH HEREIN, ITRON HEREBY DISCLAIMS ALL
OTHER WARRANTIES, OBLIGATIONS AND LIABILITIES OF ITRON, EXPRESS OR IMPLIED,
ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ALL SERVICES, EQUIPMENT, SOFTWARE,
GOODS, AND OTHER ITEMS FURNISHED BY ITRON HEREUNDER OR ANY OTHER ITEMS SUBJECT
TO THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION: (A) ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; (B) ANY IMPLIED WARRANTY
ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE OR USAGE OF TRADE; AND (C)
ANY IMPLIED WARRANTY OF NON-INFRINGEMENT.

        9.2    LIMITATION ON LIABILITY

               THE TOTAL CUMULATIVE LIABILITY OF ITRON WHETHER BASED ON
WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT LIABILITY), OR
OTHERWISE, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE PERFORMANCE OF THE
SERVICES (INCLUDING, WITHOUT LIMITATION, AMOUNTS DRAWN AGAINST THE LETTER OF
CREDIT), SHALL IN NO CASE EXCEED $30 MILLION, AND DATACOM HEREBY RELEASES ITRON
FROM ANY LIABILITY IN EXCESS OF SUCH AMOUNT. THIS MONETARY LIMITATION SHALL
SURVIVE THE FAILURE OF ANY EXCLUSIVE REMEDY.

               ITRON SHALL NOT BE LIABLE, WHETHER BASED ON WARRANTY, CONTRACT,
TORT (INCLUDING NEGLIGENCE AND STRICT



                                                                         PAGE 33

LIABILITY), OR OTHERWISE, FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, EXEMPLARY,
PUNITIVE OR INCIDENTAL LOSS OR DAMAGE, LOSS BY REASON OF SERVICE INTERRUPTION,
COSTS OF CAPITAL OR EXPENSES THEREOF, LOSS OF PROFITS OR REVENUES OR THE LOSS OF
USE THEREOF, CLAIM OF ANY THIRD PARTY FOR LOSS CAUSED BY DELAYS IN MANUFACTURE
OR OPERATION, AND DATACOM HEREBY RELEASES ITRON FROM ANY LIABILITY FOR ALL SUCH
LOSSES AND DAMAGES.

               THIS SECTION 9.2 SHALL NOT LIMIT OR RESTRICT THE AVAILABILITY
OF SPECIFIC PERFORMANCE OR OTHER INJUNCTIVE RELIEF TO THE EXTENT OTHERWISE
AVAILABLE UNDER APPLICABLE LAW.

SECTION 10. MISCELLANEOUS

        10.1   EXCUSABLE DELAY

               (a) Neither Party will be liable for, or be considered to be in
breach of or default under this Agreement because of a Force Majeure Event.

               (b) A Party affected by a Force Majeure Event shall notify the
other Party promptly after becoming aware of the Force Majeure Event, giving
details of the circumstances constituting the Force Majeure Event and the likely
duration thereof, if reasonably known, and shall keep the other Party informed
of any changes in circumstances, including when such Force Majeure Event ends.
Each Party shall also notify the other Party of any events of which it is aware
which may reasonably be expected, with the lapse of time or otherwise, to become
a Force Majeure Event. Following the receipt of such notice, the Parties shall
consult in good faith to assess the Force Majeure Event and any ways in which
the same may be avoided or its effects mitigated.

               (c) A Party affected by a Force Majeure Event shall use
reasonable best efforts to place itself in a position to fulfill its obligations
hereunder, and if unable to fulfill any obligation by reason of a Force Majeure
Event such Party shall exercise all reasonable best efforts to remove such
disability at the earliest practicable time.



                                                                         PAGE 34
<PAGE>   38

               (d) A Party's performance shall be excused only for the minimum
period necessary to return to performance hereunder through the exercise of all
reasonable best efforts. To the extent a Force Majeure Event prevents Itron from
performing any Services, DataCom shall be relieved of the obligation to make
payments for the pro rata period of time during which the Services are not
performed only if Itron is not exercising all reasonable best efforts to perform
the Services.

        10.2   NONDISCLOSURE

               Each Party will protect the Confidential Information of the other
Party from misappropriation and unauthorized use or disclosure, and at a
minimum, will take precautions at least as great as those taken to protect its
own confidential information of a similar nature. Without limiting the
foregoing, the Receiving Party will: (a) use such Confidential Information
solely for the purposes for which it has been disclosed; and (b) disclose such
Confidential Information only to those of its employees, agents, consultants,
and others who have a need to know the same for the purpose of performing this
Agreement and who are informed of and agree to a duty of nondisclosure. The
Receiving Party may also disclose Confidential Information of the Disclosing
Party to the extent necessary to comply with Applicable Law or legal process,
provided that the Receiving Party uses reasonable efforts to give the Disclosing
Party prompt advance notice thereof. Subject to the rights of DataCom under the
Escrow Agreement and the Purchase Agreement, upon request of the other Party, or
in any event upon any termination or expiration of the Term, each Party shall
return to the other all materials, in any medium, which contain, embody, reflect
or reference all or any part of any Confidential Information of the other Party.

        10.3   ASSIGNMENT

               Neither Party will assign all or any part of this Agreement or
any of its rights under this Agreement without the prior written consent of the
other Party, which may be given or withheld in such other Party's sole
discretion. However (a) either Party may assign all of its rights, title, and
interest in this Agreement, upon thirty (30) days' prior written notice to the
other Party, to an affiliate which controls, is controlled by or is under common
control with, such Party, where such successor agrees in writing to be bound by
all of the provisions of this Agreement and (b) DataCom may assign all of its
rights, title and interest in this Agreement with 30 days prior written notice
to Itron, to a non-affiliated Party which is not a competitor of Itron. No
assignment, with or without the other Party's consent, will relieve a Party from
its obligations under this Agreement. Subject to the foregoing restriction on
assignment, this Agreement will be fully binding upon, inure to the benefit of,
and be enforceable by the Parties and their respective successors and assigns.



                                                                         PAGE 35

        10.4   NOTICES

               Any notice or other communication under this Agreement given by
either Party to the other Party shall be either (a) in writing and delivered by
first class, registered, or certified U.S. mail or overnight delivery service,
return receipt requested, postage prepaid, or (b) sent by telex or facsimile and
then acknowledged as received by return telex or facsimile by the intended
recipient. Notices shall be deemed received only upon actual receipt. Notices
shall be directed to the intended recipient at the address or numbers specified
below. Either Party may from time to time change such address or numbers by
giving the other Party notice of such change in accordance with this paragraph.

               The failure of either Party to insist upon or enforce strict
performance of any of the provisions of this Agreement or to exercise any rights

Party's right to assert or rely upon



                                                                         PAGE 36

the same will be and remain in full force and effect.

        10.6   INDEPENDENT CONTRACTOR

               Each Party is engaged in an independent business and will perform
its obligations under this Agreement as an independent contractor and not as an
agent, partner, franchisee, or representative of any other Party. Neither Party
will have any right or authority to create any obligation or make any
representation or warranty in the name or on behalf of the other Party.

        10.7   COUNTERPARTS

               This Agreement may be executed in any number of counterparts,

        10.11  DISPUTE RESOLUTION

               (a) Any dispute, controversy or claim arising out of or relating
to this Agreement (including all schedules and exhibits that are related to or
incorporated by the Agreement) or the breach, termination or validity thereof (a
"DISPUTE") shall be submitted to management of the Parties for resolution. In

                                                                         PAGE 37
<PAGE>   41

court of competent jurisdiction, or the Parties may, by mutual agreement, agree
to proceed with arbitration in accordance with Paragraph 10.11(b).

               (b)    Arbitration.

                      (i) Disputes may, by mutual agreement of the Parties, be
referred to arbitration administered by the American Arbitration Association
(the "AAA") under its Commercial Arbitration Rules then in effect (the "RULES")
except as modified herein. The arbitration shall be held in Pittsburgh,
Pennsylvania.

                      (ii) There shall be three arbitrators of whom each Party
shall select one within five (5) days of respondent's receipt of claimant's
demand for arbitration. The two Party-appointed arbitrators shall within five
(5) days of the selection of the second arbitrator, select a third arbitrator to
serve as chair of the tribunal, who shall be qualified by professional
experience and education to rule upon the issue presented. If any arbitrator has
not been appointed within the time limits specified herein, such appointment
shall be made by the AAA upon the written request of either Party within five
(5) days of such request.

                      (iii) The hearing shall be held no later than forty-five
(45) days following the appointment of the last of the three arbitrators and the
award shall be rendered no later than fifteen (15) days following the close of
the hearing.

                      (iv) The arbitral tribunal shall permit prehearing
discovery that is relevant to the subject mater of the Dispute taking into
account the Parties' desire that the arbitration be conducted expeditiously and
cost effectively. All discovery shall be completed within forty-five (45) days
of the appointment of the third arbitrator.

                      (v) The award of the arbitrators shall be final and
binding between the Parties, and a judgment may be entered enforcing it in any
court having jurisdiction over the Parties.

                      (vi) Each Party shall bear its own costs of arbitration,
and the costs of the arbitrators shall be divided equally between them. If a
Party chooses to file an appeal, however, and does not substantially prevail on
the merits of its claim, that Party shall bear all of the reasonable costs and
expenses of both Parties for the appeal.

               (c) Continued Performance. This Agreement and the rights and
obligations of the Parties shall remain in full force and effect pending the
resolution of any Dispute in any arbitration proceeding hereunder, and both
