Delaware corporation, ("Operator"), with its headquarters at 1101 Kermit Drive,
Suite 800, Nashville, TN 37217.

         WHEREAS, Operator currently owns or operates twenty-eight (28)
full-service travel plaza truckstops which are located at the addresses listed
on Schedule 1 hereto; and (ii) may acquire or contract to operate other
full-service travel plaza truckstops, all of the aforesaid hereinafter
individually being referred to as a "Truckstop" and collectively being referred
to as the "Truckstops"; and

         WHEREAS, PNV has designed and developed the concept and equipment ("the
System") to (i) enable truck drivers to: (a) receive and/or have access to cable
television services and telecommunications services; and (b) provide such truck
drivers programming consisting of video and audio services, and telephone, fax
or other data services while remaining in their vehicles parked at the
Truckstop; and (ii) sell advertising to be broadcast over the System
(collectively, the "Services"); and

         WHEREAS, Operator desires to engage PNV to install the System and
provide the Services at certain of the Truckstops.

         NOW THEREFORE, in consideration of the mutual promises and covenants
contained herein, Operator and PNV (hereinafter collectively being referred to
as the "Parties"), intending to be legally bound, hereby mutually agree as
follows:

         1.       Purpose. The Parties hereby agree that PNV shall initially
install the System and the parties shall operate the System and provide the
Services at the Truckstop(s) on Schedule 1 pursuant to a build out schedule to
be mutually agreed upon by the Parties.

         2.       Installation of Equipment.

                  (a)      PNV shall, at its sole cost and expense, and in the
manner herein provided, install and continually maintain at each Truckstop at
which the Services are to be provided all equipment necessary to provide the
Services including the following:

                           (i)      equipment necessary for the provision and
                                    distribution of the Services.

                           (ii)     outlet ports to parking spaces to provide
                                    users with access to the Services.

                           (iii)    equipment to (a) monitor the use of the
                                    Services and (b) account for all receipts
                                    for billing and revenue sharing purposes.

All of the foregoing equipment as currently used by PNV is described on Schedule
2 hereto and is hereinafter, together with any additions or deletions to said
equipment, collectively referred to as the "PNV Equipment". PNV reserves the
right to make additions to and deletions from the PNV Equipment to be installed
at each Truckstop. PNV shall provide the Services to at least 75% of the truck
parking spaces located at each Truckstop at which it installs the System. The
Parties shall mutually determine the precise number and location of the truck
parking spaces at which the Services shall be provided, taking into account such
factors as the cost of construction and implementation, the layout of the
parking facilities, the usage of particular parking rows to drop trailers and
such other factors as the Parties may deem relevant.

                  (b)      Operator shall make available to PNV a sufficient
area in which to install the PNV Equipment including: (i) such area as is
required for the installation of satellite dish(es); (ii) a secured
air-conditioned interior area of approximately 50 square feet for the
installation of the headend equipment and the telephone and related monitoring
equipment; and (iii) an area at the fuel desk and/or the travel store for
installation of the equipment required for activation of the Services
(hereinafter collectively referred to as the "Equipment Area"). PNV shall be
entitled to have continued access to the Equipment Area and all parking areas
for purposes of installing, repairing and monitoring the PNV Equipment, the
System and the Services.

                  (c)      Prior to commencement of construction at any
Truckstop, PNV shall obtain Operator's approval of the methods and materials to
be used by PNV with respect to the installation of the System. PNV will repair
any damage to the Truckstop which is caused by PNV. However, PNV shall not be
responsible for any existing defects or deficiencies or the normal wear and tear
to the parking lot or the Truckstop.

                  (d)      PNV shall install the PNV Equipment in a workmanlike
and efficient manner, without unreasonable interference with the operation of
each Truckstop. PNV shall use its best efforts to: (i) minimize the disruption
to traffic flow and parking space availability; and (ii) complete the
installation of the System at each Truckstop within forty-five (45) days of
commencement of the installation at each Truckstop.

                  (e)      PNV shall on a timely basis secure, and continuously
maintain in full force and effect, all licenses, permits and approvals required
by governmental authorities with respect to the installation, operation and
maintenance of the System and providing the Services. Operator shall assist PNV
(at PNV's expense) in obtaining any such licenses, permits, or approvals upon
PNV's reasonable request.

                  (f)      The Parties agree that while PNV shall use reasonable
efforts to complete the installation of the System at the Truckstops pursuant to
the terms of this Agreement, PNV's obligations to install the System at any of
the Truckstops is subject to: (i) Operator having ownership or control over such
Truckstop at the time PNV commences installation of the System; (ii)
confirmation that the Truckstop has, in PNV's sole discretion, a sufficient
number of parking stalls to warrant installation; (iii) Operator authorizing PNV
to use its standard


                                      -2-

construction methods and materials with respect to the installation of the
System at such Truckstop; (iv) completion of satisfactory engineering and
environmental surveys at such Truckstop; (v) confirmation that no part of the
System crosses a public right of way adjacent to such Truckstop; (vi) receipt
from Operator of all requested maps, blue prints and other relevant information
relating to such Truckstop on a timely basis; and (vii) PNV not being able to
complete any such installation because of any of the following: floods, civil
unrest, acts of God; war; governmental interference or embargoes; labor strikes;
failure of others to supply fuel, power, materials or supplies; transportation
delays by third parties; or any other cause (whether or not similar to those
described in this Section 2(f)) beyond the control of PNV.

                  (g)      After completion of the installation of the System at
a Truckstop, PNV shall provide Operator with notice of the date on which the
sale of the Services shall commence at each such Truckstop (hereinafter referred
to as the "Truckstop Service Date").

         3.       Rights and Duties of The Parties With Respect To The PNV
Equipment.

                  (a)      Notwithstanding the fact that certain parts of the
PNV Equipment may be affixed to each Truckstop, the PNV Equipment shall not
become a fixture thereto and shall remain the property of PNV. Operator
acknowledges that the System, the Services and the PNV Equipment and the manner
of its operation and installation are proprietary to PNV. Accordingly, Operator
shall use its best efforts to insure that all material confidential information
and data concerning the System, the Services and the PNV Equipment shall not be
divulged, and (except in the case of emergency) that access to the System and
the PNV Equipment shall not be given to any person or persons other than
personnel authorized by PNV.

                  (b)      Upon the termination of this Agreement for any
reason, PNV shall have the right to: (i) remove, at its sole cost and expense,
any or all of the PNV Equipment from each Truckstop; or (ii) if agreeable to
Operator, sell or lease it to the Operator or its successors, nominees or
assignees. PNV shall, if it elects to remove the System, restore each Truckstop
as near as reasonably possible to the condition of such premises prior to the
installation of the System, normal wear and tear excepted, but shall not be
obligated to remove any underground cables.

         4.       Programming and Telecommunications Services to Be Provided.

                  (a)      PNV shall make the Services available on the System
as follows:

                           (i)      PNV shall source and deliver a programming
                                    package consisting of a minimum of eleven
                                    (11) channels of entertainment programming.
                                    PNV shall pay the cost of all such
                                    programming. The current programming
                                    schedule to be broadcast by PNV is as set
                                    forth on Schedule 3. PNV may make changes to
                                    the programming schedule from time to time.

                           (ii)     In addition to the eleven (11) channel
                                    entertainment lineup, there shall be other
                                    channels which shall be used to provide a
                                    programming schedule and advertising.

                           (iii)    PNV may, with the consent of Operator,
                                    provide pay-per-view or other
                                    non-traditional cable channels or services
                                    as part of the Services.

                           (iv)     PNV shall also provide telephone service to
                                    certain parking slots at each Truckstop. The
                                    current telephone services offered by PNV
                                    are set forth on Schedule 4. PNV shall, with
                                    Operator's prior consent, have the right to
                                    determine and make changes to the specific
                                    types of telecommunication services provided
                                    to a particular Truckstop from time to time.
                                    If the Parties mutually agree to permit PNV
                                    to provide phone service to areas of the
                                    Truckstops, other than the parking lot, the
                                    Parties shall mutually agree as to the
                                    profit allocations with respect to such
                                    services.

         5.       Operation of the System and Sale and Promotion of the
Services.

                  (a)      Initially, upon installation of the System at any
Truckstop, PNV shall train the Operator and its designated employees with
respect to the maintenance and operation of the System and the promotion of the
Services. PNV shall provide follow up training for Operator's personnel during
working hours with respect to the promotion of the Services, the operation of
the System, and the maintenance of the PNV Equipment as may be reasonably
requested by Operator from time to time. PNV shall, with the prior consent of
Operator, be entitled to have its own employees or agents engage in the
promotion of the Services at any Truckstop, provided that PNV's employees and
agents shall not interfere with the operation of said Truckstop.

                  (b)      Operator shall use its best efforts to assure that
the management, fuel desk employees and other personnel promote the use of the
Services by the truck drivers frequenting the Truckstops. The Parties may
mutually agree from time to time to implement sales incentive programs for the
fuel desk employees and other personnel to promote the sale of the Services. The
Parties shall share the cost of implementing and funding any such mutually
agreed upon incentive programs.

                  (c)      Operator may develop and supply to PNV, at no cost to
PNV, certain advertising and promotional materials relating to the Operator's
truckstop system to be run on a single dedicated channel to be made available to
Operator at no cost. Additional channels may be provided for Operator's use at
mutually agreed upon charges. PNV may also develop and supply to Operator, at no
cost to Operator, certain advertising and promotional materials relating to the
System and the sale of the Services. Subject to each Party's approval and
consent, Operator and PNV shall make reasonable efforts to utilize and display
such materials at each Truckstop in order to promote the sale and promotion of
the Services.

                                    and removal of debris (i.e. oil, dirt, ice,
                                    snow, etc.); and (iii) replace cable and
                                    phone connection outlets in the outside

                           (ii)     If a mechanical problem arises other than
                                    through a failed connecting cable or
                                    accessory, Operator shall contact PNV by
                                    telephone at PNV's office. Unless
                                    extenuating circumstances exist, PNV shall,

                                    will be billed directly to PNV.

         7.       Term. Subject to Section 16, the term of this Agreement, as it
applies to each Truckstop at which the System is installed, shall be for a
period of ten (10) years commencing on the Truckstop Service Date and
terminating on the tenth anniversary of the Truckstop Service Date (the "Term").
Subject to Section 16 and Operators written consent, the Term shall
automatically be extended for a five (5) year renewal period (the "Automatic
Renewal Term") provided that, as a condition to the commencement of the
Automatic Renewal Term, Operator shall be entitled to receipt of the increased

Refusal"). In the event that PNV desires to exercise its Right of First Refusal,
PNV shall provide written notice thereof ("First Refusal Notice") to Operator
within thirty (30) days of receipt of the New Service Notice. For a period of
thirty (30) days after the date of the First Refusal Notice, Operator and PNV
will negotiate in good faith the terms upon which PNV will provide the New
Services to Operator. If after such good faith negotiations, PNV and Operator


                                      -5-

are unable to agree upon the terms and conditions upon which PNV will provide
Operator with the New Services or if PNV is unable to provide the New Services
for any reason, then Operator shall pay PNV liquidated damages in accordance
with Section 7(b) hereof and terminate this Agreement.

                  (b)      If at any time after the fifth anniversary of this
Agreement, (i) Operator terminates such Agreement after following the Right of
First Refusal procedure set forth in Section 7(a) hereof or (if Operator does
not intend to obtain New Services) for any other reason, or (ii) PNV terminates
such Agreement as a result of Operator's material breach of such Agreement, then
Operator shall pay PNV liquidated damages in the following amounts: (1) $200,000
for each applicable truckstop that contains up to 100 stalls and $2,000 for each
additional stall over 100 if such termination occurs on or after the fifth

anniversary of this Agreement; (3) $100,000 for each applicable truckstop that
contains up to 100 stalls and $1,000 for each additional stall over 100 if such
termination occurs during the first quarter of the tenth year of this Agreement;
(4) $75,000 for each applicable truckstop that contains up to 100 stalls and
$750 for each additional stall over 100 if such termination occurs during the
second quarter of the tenth year of this Agreement; (5) $50,000 for each
applicable truckstop that contains up to 100 stalls and $500 for each additional
stall over 100 if such termination occurs during the third quarter of the tenth
year of this Agreement; and (6) $25,000 for each applicable truckstop that
contains up to 100 stalls and $250 for each additional stall over 100 if such
termination occurs during the fourth quarter of the tenth year of this
Agreement. In the event that Operator terminates this Agreement as a result of
PNV's material breach of such Agreement, Operator shall not be required to pay
PNV liquidated damages as specified in this Section 7(b) hereof.

         8.       Fees.

                  (a)      All revenues and profits derived from the sale or
provision of the Services at each Truckstop shall, during the Term (and any
renewal terms) be allocated between PNV and Operator as set forth as Schedule 5
attached hereto.

                  (b)      The books and records of the Operator and PNV
pertinent to the Gross Receipts (as defined on Schedule 5), Net Profits (as

         13.      Risk of Loss and Insurance; Indemnification.

                  (a)      PNV shall bear the risk of loss and hereby
indemnifies and holds harmless Operator for: (i) damage to or destruction of the
PNV Equipment and the System installed at each Truckstop, except as provided in
Section 13(b); and (ii) injury to persons or damage to property arising from the
installation of the PNV Equipment and the System (except to the extent such
damage is occasioned by the gross negligence or willful misconduct of Operator,
its employees, contractors or agents).

                  (b)      Operator shall be responsible for the maintenance,
repair or replacement of the PNV Equipment resulting from damage or destruction
caused by the gross negligence or willful misconduct of the Operator, its
employees, contractors or agents.

                  (c)      Both Operator and PNV shall maintain during the Term
of this Agreement (or any renewal term), at their sole cost and expense,
comprehensive public liability insurance in the minimum amount of $1,000,000
providing coverage at each Truckstop at which the Services are provided against
any personal injury or other claims relating to the operation or use of the
System or the sale or provision of the Services and shall ensure that each Party
is named as an additional insured in respect of such insurance or is otherwise
covered as its interest may appear.

         14.      Force Majeure. Neither party shall have any liability for the
failure to perform or a delay in performing any of its obligations if such
failure or delay is the result of any legal restriction, labor dispute, strike,
boycott, flood, fire, public emergency, revolution, insurrection, riot, war,
unavoidable mechanical failure, interruption in the supply of electrical power
or any other cause beyond the control of any party acting in a reasonable
business-like manner, whether similar or dissimilar to the causes enumerated
above.

         15.      Assignment.

                  (a)      Operator may sell, assign, transfer or otherwise
dispose of its interest in one or more of the Truckstops (through a change of
control, sale of assets or otherwise) provided that the acquiror of such
interest or assets shall assume the Operator's rights and obligations hereunder
and shall be bound by the terms of this Agreement, in which case, PNV shall
recognize the acquiror of such Truckstop as its Operator for purposes of this
Agreement.

                  (b)      PNV may pledge its interest in this Agreement to any
party, including without limitation, to any bank, recognized lending or leasing
institution or investor as collateral. PNV may sell, assign, transfer or
otherwise dispose of its interest in this Agreement provided that said acquiror
shall assume all of PNV's rights and obligations hereunder and shall be bound by
the terms of this Agreement.

         16.      Breach. In the event that either party shall fail in any
material respect to perform any obligation under this Agreement, the other party
may in writing notify the non-performing party that such failure constitutes a
breach. If the breach is not remedied or cured within thirty (30) days following
receipt of the notice of breach, without limiting any other remedy which may

the breaching party.

         17.      Ownership and Confidentiality. Operator recognizes and agrees
that PNV shall, during the term of this Agreement and thereafter, retain sole
ownership of the System and the PNV Equipment. Operator recognizes the
proprietary nature of the concept and the design of the System, the PNV
Equipment and the Services. Accordingly, Operator agrees to maintain and cause
each of its employees and agents to maintain and keep strictly confidential all
confidential information that it obtains or receives in conjunction with the
System, the PNV Equipment and the Services. Operator further agrees that the
"Park N' View" name and logo shall be and remain the property of PNV and all
