                       PETRO PARTS AND SERVICE AGREEMENT

      This Agreement is made this 3rd day of May, 2000 by Volvo Trucks North
America, Inc. (hereinafter called "Volvo"), a Delaware corporation with its
principal place of business in Greensboro, North Carolina, and Petro Stopping
Centers, L.P. (hereinafter called "Petro") a Delaware Limited Partnership with
its principal place of business in El Paso, Texas.

      WHEREAS Volvo desires to establish Petro as a parts and service center in
the dealer's Area of Responsibility; and

      WHEREAS Petro desires to act as such parts and service center,

  NOW, THEREFORE, in consideration of the mutual covenants contained herein,
Volvo and Petro (sometimes hereinafter jointly the "Parties") do agree as
follows:

  1. Appointment. Petro owns and operates truckstop facilities ("Truckstops")
     -----------
located in the same geographic area as one or more of Volvo's franchised dealers
("Dealer").  Each Petro location will work in conjunction with the appropriate
Dealer, designated by Volvo in accordance with the provisions of this agreement.
Volvo hereby grants to Petro, with the concurrence and agreement of the Dealer,
and Petro hereby accepts from Volvo, the non-exclusive right to act as an
authorized parts and service center of Volvo, providing parts for and service to
trucks under the VOLVO nameplate and such other nameplates as Volvo shall
designate (hereinafter the "Trucks"). Petro shall not be, and nothing contained
in this Agreement shall be deemed to authorize Petro to act as, a dealer for the
sale of any new trucks or other vehicles manufactured or distributed by Volvo.

  2. Area of Responsibility. Based upon this Agreement, Petro shall act as a
     ----------------------
parts and service center for Volvo in the locations set forth on Schedule A
attached hereto and made a part hereof (the "Area of Responsibility"). Petro
shall operate its parts and service center at the Truckstops located at such
other locations within the Area of Responsibility as the Parties may from time
to time agree upon (the "Premises").  Schedule A shall be amended from time to
time, upon agreement of the parties, as Petro opens new Truckstop locations.

  3. Evaluation of Sales Performance. Petro agrees  to purchase/sell parts
     -------------------------------
consistent with objectives agreed to by the parties.

  4. Service - General. Petro will provide a limited range of repair services
     -----------------
for Trucks at Petro's Truckstops in the Area of Responsibility, regardless of
where the Trucks were purchased. This will include service paid for by
customers, as well as light  warranty service.   Petro also agrees to provide
Contract Maintenance and MVP Care services to vehicles as requested by Volvo.
Petro agrees to refer all other service work outside of Petro's capabilities, to
Dealer.  All service work performed by Petro will be performed and administered
in a professional manner.

  In servicing Trucks, Petro will follow instructions contained in service
manuals and bulletins issued by Volvo. Petro will maintain on its Premises all
service equipment, and any special tools, which are required or desirable to
provide economical and efficient service to users of Trucks. If and when Volvo
makes available new models or types of Trucks, Volvo will provide, at its
expense, any additional equipment or special Volvo tools required to service the
new models or types of Trucks.

  Petro understands that customers have the right to expect that any part which
Petro sells, installs, or uses in the repair or servicing of Trucks meets the
high quality standards of Volvo. Petro agrees that it will not knowingly sell,
use, or install non-genuine VOLVO parts or parts not meeting Volvo's
specifications, or which are not equal in quality and design to genuine VOLVO
parts. Petro further agrees that it will not knowingly sell or offer for sale as
genuine VOLVO parts any parts which are not in fact new genuine VOLVO parts, and
in any case where Petro sells a non-genuine VOLVO part, it shall disclose such
fact to the customer and advise the customer that the item is not included in
warranties furnished by Volvo.

  5. Warranty and Special Policy Service. Petro will perform light warranty
     -----------------------------------
services on all Trucks, regardless of where they were purchased, in accordance
with warranty policies established by Volvo, and will perform any other service
to Trucks specially requested by Volvo which are within the scope of this
Agreement.  Volvo will reimburse Petro for all parts or other materials and will
pay Petro, at published labor rates, for necessary labor used by Petro in
providing light warranty or special service. Petro, as instructed by Volvo, will
retain for up to 30 days, or dispose of parts replaced by Petro in performing
light warranty or special service. Petro shall not charge customers for any
light warranty or special service which is to be paid for by Volvo.

  6. Recall Service.  Petro will, at the request of Volvo, provide Volvo with
     --------------
all information in Petro's possession to assist Volvo in notifying customers of
the need for or desirability of recall inspections or repairs. Petro shall refer
all Volvo sponsored Recall work to Dealer.

  7. Customer Relations.  Petro will receive, investigate and handle complaints
     ------------------
of owners or users of Trucks in a manner which will secure the goodwill of the
owners and users and the public toward Petro, the Trucks and Volvo. Except as
expressly provided in this Agreement, or approved in advance by Volvo, Petro
investigation and handling of complaints will be at Petro's expense.  If Petro
receives any complaints regarding Volvo warranty work which it cannot resolve to
the customer's satisfaction, Petro will promptly inform Volvo of the nature of
the complaint, the identity of the person making the complaint and the serial
number of the Truck or part to which it relates.

  8. Compliance with Law. Volvo and Petro will at all times comply with all
     -------------------
laws, and maintain in effect all required licenses and permits, applicable to
the activities conducted by them or the locations at which they are conducted.
Volvo represents to Petro that to the best of Volvo's knowledge and belief that
this Agreement and the performance of the terms hereof does not violate any law,
statute, ordinance, rule or regulation to which Volvo is subject to or violate
the terms of any contract or agreement to which Volvo is a party.

  9. Location, Facilities, Signs. Petro will maintain the Premises in good
     ---------------------------
repair and in accordance with Petro's policies as in effect from time to time
regarding appearance, size and layout of facilities for sales of parts and
accessories and service operations.

  Petro will permit Volvo to display signs in the lube bay(s) and provide other
sales materials for distribution as agreed to by Volvo and Petro at the
Truckstops.

  10. Inventories. Subject to availability and delivery, Petro will at all times
      -----------
carry an inventory of parts sufficient to meet the minimum parts stocking
guidelines as agreed to by Volvo and Petro annually and maintain a prescribed
inventory of Volvo proprietary parts and have trained technicians on each shift.

  11. Training. Petro shall maintain a sufficiently trained staff to complete
      --------
the warranty repair and other repair obligations of this Agreement. Volvo will
make available to Petro training programs that Volvo deems appropriate in
assisting Petro to fulfill its obligations under this Agreement.  Volvo will
provide, at its expense for a period of one year from the date of this
agreement, training uniquely related to Volvo products or services.  Costs for
offsite training  or training beyond the first year of this Agreement will be
borne as mutually agreed to by Volvo and Petro.  The cost of all other training
shall be borne by Petro.  Only qualified mechanics or technicians shall perform
Volvo warranty repairs.

  12. Special Tools. Volvo shall provide, at Volvo's expense, those special
      -------------
tools prescribed by Volvo for servicing trucks pursuant to this Agreement.
Petro agrees to maintain all such tools and equipment in good condition,
ordinary wear and tear excepted, and Petro shall be solely responsible to Volvo
for any other damage, theft or destruction.  At the termination of this
Agreement for any reason, Petro shall return to Volvo, within ten (10) days, all
such special tools or equipment provided by Volvo.

  13. Parts  Sales to Petro.  Parts sold to Petro, either through Dealer or
      ---------------------
directly from Volvo, shall be sold to Petro at a price not to exceed National
Fleet Prices as established by Volvo from time to time.  All parts used in
warranty repairs, or any other repair reimbursable by Volvo, either whole or in
part, shall be purchased from Volvo or Dealer.  All parts or other materials

<PAGE>

  14. Advertising Materials. Volvo will provide Petro with advertising, sales
      ---------------------
promotion and marketing materials relating to parts.

  15. Service, Parts Manuals. Volvo will provide and charge per policies in
      ----------------------
effect for service and parts manuals and such other materials as Volvo deems
appropriate in order to assist Petro in fulfilling its obligations under this
Agreement.

  16. [Deleted].

  17. Parts Return.  Volvo will process requests for parts returns and
      ------------
adjustments in accordance with Volvo's policies in effect from time to time.
This includes discontinued dealer salable parts returns. The parts return
privileges detailed in this agreement, shall be applicable to Petro only.

  18. Petro Orders. Petro will order parts from Dealer or Volvo directly,
      ------------
subject to parts availability and/or as instructed by Volvo.  Billing for such
parts will be handled by a third-party billing company.  Petro may cancel orders
once they are accepted by Volvo, except as specifically otherwise permitted
hereunder or pursuant to Company policies as in effect from time to time.  If
Volvo is notified in writing by Petro of repeated Dealer nonperformance, Volvo
will make every reasonable attempt to intervene and have such Dealer performance
deficiencies corrected.  If problems continue, Volvo will change the Dealer
assigned to Petro, or sell parts directly to Petro.

  19.  Prices. The prices Petro will pay the Dealer for parts sold to it by
       ------
Dealer,  and ordered from Volvo, or parts purchased directly from Volvo, shall
not exceed those shown on Volvo's National Fleet price lists in effect from time
to time, or in other publications issued by Volvo. Subject to Volvo's policy
from time to time regarding prior commitments by Dealers, unless otherwise
specified, each change in price or other terms will apply to all parts delivered
after the date it becomes effective, even if they were ordered before that date.
However, after Petro is informed of a price increase, Petro may cancel or modify
orders for parts which are the subject of that price increase in accordance with
Volvo policies in effect from time to time.

  20. Terms of Sale Grant of Purchase Money Security Interest. If at any time,
      -------------------------------------------------------
Volvo sells parts or other materials directly to Petro, terms of payment and
other terms of sale of parts will be in accordance with Company policies as in
effect from time to time. To secure its indebtedness to Volvo for parts
purchased directly from Volvo (the "Secured Indebtedness"), Petro grants to
Volvo a purchase money security interest in that portion of Petro's parts
inventory purchased directly from Volvo (the "Collateral"). The grant of such
purchase money security interest shall not affect Petro's right to sell its
parts inventory in the ordinary course of its business. Petro shall, at Volvo's
request, execute such documents for public filing as are necessary, in Volvo's
judgment, to perfect the purchase money security interest hereby granted. Upon a
default by Petro in the payment of any Secured Indebtedness, Volvo shall have
all the rights of a secured party under the Uniform Commercial Code. Petro
warrants and covenants that, so long as it has any outstanding Secured
Indebtedness: (i) the Collateral will be retained in Petro's possession at
Petro's sole risk and responsibility at all times prior to final retail use or
sale; and (ii) Petro's ownership of its parts inventory is solely for sale in
the ordinary course of its business. The purchase money security interest hereby
granted shall survive a termination of this Agreement for any reason if, at the
time of such termination, any Secured Indebtedness remains unpaid.

  21. Delivery. Delivery of the parts will be as stated by Volvo policies per
      --------
the type of order for parts ordered directly from Volvo. Volvo will not be
responsible for a failure or delay in accepting orders or delivering parts if
the failure or delay is due in whole or in part to an excess of orders, changes
in production schedules, discontinuance of the manufacture or sale of specific
parts, labor difficulties, labor, material, transportation or utilities
shortages, government regulations, or other causes beyond Volvo's control.  For
parts ordered through Dealer, delivery terms will be as agreed to between Petro
and Dealer.

  22. Shipping Point and Mode of Delivery. For parts purchased directly from
      -----------------------------------
Volvo, shipping charges are determined by type of order in accordance with
company policy. Petro will pay all demurrage, storage, and other charges
accruing after arrival of any shipment of parts at their destination. Volvo will
attempt to comply

                                       3
<PAGE>

with Petro's instructions as to routing and mode of transportation, but Volvo
will make the final decision as to routing and mode of transportation of all
parts. Risk of loss or damage will be transferred to Petro when parts are
delivered to and received by Petro. Volvo will cooperate fully with Petro in
attempting to recover compensation from carriers for loss or damage in shipment.

  23. Failure of Petro to Accept Delivery. If Petro fails or refuses to take
      -----------------------------------
delivery of any parts which Petro has ordered from Volvo or Dealer, Volvo may,
without prejudice to its right to other remedies, charge Petro a cancellation
charge.

  24. Warranty. Volvo will provide each customer of Petro a limited parts
      --------
warranty relating to Volvo parts sold to the customer by Petro in accordance
with Volvo's customer warranty policies in effect from time to time. VOLVO MAKES
NO OTHER WARRANTIES WHATSOEVER, WHETHER WRITTEN OR ORAL, EXPRESS OR IMPLIED, TO
DEALER, PETRO OR THEIR RESPECTIVE CUSTOMERS, INCLUDING ANY WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSES.

  25. Use of Trademarks and Trade Names.  Petro will not use any of Volvo's
      ---------------------------------
trademarks, service marks or trade names for any purpose or in any context which
in Volvo's opinion is likely to injure the reputation of Volvo or its products
or to impair the enforceability of any of Volvo's trademarks, service marks or
trade names.  Likewise, Volvo will not use any of Petro's trademarks, service
marks or trade names for any purpose or in any context which in Petro's opinion
is likely to injure the reputation of Petro or its products or to impair the
enforceability of any of Petro's trademarks, service marks or trade names.

  26.  Audit Rights.  Volvo shall have the right, upon reasonable advance
       ------------
written notice, to audit the accounting or other records of Petro.  This
examination may include, among other things, an audit of Petro's records
supporting warranty or other claims made against Volvo, and the records relating
to the purchase and sale of parts and other materials pursuant to this
agreement.  Petro shall provide all reports at such times and on such forms as
may be reasonably requested by Volvo.

  27. Termination by Advance Notice.   This Agreement shall remain in effect
      -----------------------------
until it is terminated by either party as provided in this section.

  a. The parties may at any time terminate this Agreement by mutual consent.

  b. Petro may at any time terminate the Agreement by giving written notice of
termination to Volvo and the Dealer. Such notice of termination shall specify
the date upon which the termination is to become effective and not less than one
(1) year shall intervene between the giving of such notice and the effective
date.

  c. Volvo may terminate the Agreement at any time by giving the Dealer and
Petro written notice of termination. Such notice of termination shall specify

year shall intervene between the giving of such notice and such effective date.

  d.  Petro may terminate this Agreement with respect to any particular
Truckstops and amend Schedule A, at any time by giving Volvo and Dealer written
notice of termination.  Such termination shall specify the date upon which the
termination is to become effective and not less one (1) year shall intervene
between the giving of such notice and such effective date.  If, in Volvo's sole
discretion, in the exercise of its reasonable business judgment, such
terminations by Petro reach an unreasonable number, Volvo may terminate this
Agreement in its entirety upon 90 days prior written notice to Petro.

  e. Upon the effective date of termination, all indebtedness of Petro to Volvo
or to any subsidiary or affiliate of Volvo, incurred as a result of this
Agreement, shall become immediately due and payable and, unless otherwise agreed
between the parties, all unfilled orders accepted from Petro shall be deemed
canceled, without liability on the part of either party, or upon mutual
termination, Volvo at its option may establish terms of cash with order or
C.O.D. on any or all parts thereafter delivered to Petro.

  28.  Termination by Immediate Notice. It is the hope and expectation of the
       -------------------------------
parties that this Agreement will create an enduring and mutually profitable
relationship. However, it is recognized that circumstances may arise

                                       4
<PAGE>

requiring Volvo to take steps to protect its interest and making it
impracticable for the relationship to continue, and under which this Agreement
should be immediately terminated. In order that those circumstances may be
clearly understood, it is agreed that:

  a. Notwithstanding any other provisions of this Agreement, Volvo may, at its
option, by written notice, terminate the Agreement effective at once, or Volvo
or any subsidiary of Volvo may without notice declare immediately due and
payable any indebtedness of Petro to Volvo, or any such subsidiary, for parts
sold directly to Petro, and may immediately and without notice repossess such
parts as well as any other parts or assets in Petro's possession with respect to
which Volvo or any subsidiary or affiliate of Volvo has a lien, encumbrance or
security interest, or may without notice establish terms of cash with order or
C.O.D. on parts thereafter delivered to Petro, or may exercise any other legal
remedies that are available to it, upon the happening of any of the following:

    1. Petro defaults in the payment of any obligations owing to Volvo or to any
       subsidiary of Volvo, or upon demand fails to account for the proceeds of
       the sale of parts for which it is indebted to Volvo or any subsidiary of
       Volvo;

    2. Petro sells or makes an attempted sale or other distribution of any parts
       purchased under this Agreement, upon which any part of the purchase price
       is unpaid, other than in the ordinary course of trade;

    3. Without prior approval of Volvo, Petro sells or attempts to sell in bulk
       all or a major portion of his inventory purchased from Volvo, whether or
       not any part of the purchase price therefor remains unpaid;

    4. An assignment by Petro for the benefit of creditors;

    5. The admitted insolvency of Petro or the institution of voluntary or
       involuntary proceedings in bankruptcy or under other insolvency law, or
       for an arrangement with creditors or for corporate reorganization or for
       receivership or dissolution of the Dealer or Petro;

    6. The assignment or attempted assignment of this Agreement, or of any
       interest therein or any right thereunder, by Petro without Volvo's
       written consent;

    7. The falsification of records or reports by Petro in a material respect.

In all such cases, with the exception of subsections (5) through (7), Petro
shall be given thirty (30) days to cure such deficiency after receiving written
notice of such from Volvo.

   b. The exercise of one right or remedy shall not constitute an election of
remedies or preclude Volvo from exercising all other rights or remedies
available to it under the law or as provided herein, and the acceptance by Volvo
or any subsidiary or affiliate of Volvo of the payment of any past due
indebtedness owing to either of them shall not constitute a waiver of any of the
rights of Volvo under this section arising out of the existence of such past due
indebtedness.

   c. Volvo may by written notice terminate any Petro Truckstop location and
amend Schedule A, effective at once, if any state or jurisdiction where this
Agreement is to be performed requires a license of Petro and Petro fails to
secure or maintain or renew such license for the Petro Truckstop location, or
such license is suspended or revoked for any reason.

   d. The termination of this Agreement under this section shall, unless
otherwise agreed between the parties, cancel all unfilled orders accepted from
Petro, without liability on the part of either party. Alternatively, Volvo will
have the option to cancel or fill any unfilled orders placed by Petro for parts.

   e.  Any sum owed by Petro to Volvo, as a result of this Agreement, will be
due immediately upon termination.

   29.  Rights and Obligations Upon Termination.
        ---------------------------------------

   a.  Volvo will have the option to purchase any removable business signs which
belong to Petro and bear a Volvo trademark, service mark, or trade name. The
purchase price will be the amount, net of depreciation, at which the signs were
purchased by Petro and Volvo shall repair all damage to the Premises occasioned
thereby, normal wear and tear excepted.  For any signs or sub-branded trade or
service marks not covered or addressed by the operation agreement between Volvo
and Petro, Volvo may remove such signs at its sole cost and expense and restore
all affected premises or fixtures to their original condition, normal wear and
tear excepted.  Volvo will retain all ownership rights in any sub-branded trade
or service marks.

   b.  Petro shall immediately stop using in any way any of Volvo's trademarks,
service marks or trade names, including sub-branded trade or service marks, or
other marks or names so nearly resembling those of Volvo as to be likely to
cause confusion or mistake. Likewise, Volvo shall immediately stop using in any
way any of Petro's trademarks, service marks or trade names or other marks or
names so nearly resembling those of Petro as to be likely to cause confusion or
mistake.

   c.  Petro will indemnify Volvo against, and hold it harmless from, any
liability, costs or expenses (including attorneys' fees) resulting from Petro's
failure to pay all sums due under agreements by which Petro finances the
purchase of parts or maintenance of its inventory of parts.  Both parties will
indemnify each other against any breach of this Agreement or the breach of any
representations or warranties made herein.

   d.  Within 30 days of the effective date of termination of this Agreement,
Petro also agrees to return to Volvo, if requested, any or all catalogs,
microfiche, price lists, bulletins, and current advertising material, which have
been furnished to Petro by Volvo. Any charges (except for transportation,
subscription service and binders) paid by Petro to Volvo for such material will
be credited to Petro when such material is returned to Volvo. Amounts credited
to Petro under this section will not be payable until Petro has complied with
all applicable provisions of law relating to bulk transfers and has complied
with all requirements regarding the returns of signs, catalogs, microfiche,
price lists, bulletins, and advertising material and has submitted evidence
satisfactory to Volvo that all such materials are free and clear of all liens
and encumbrances (other than liens and encumbrances of Volvo or any subsidiary
or affiliate of Volvo). When payable, the amount may be paid to Petro in cash or
credited to Petro's notes or account or other obligations to Volvo or to any
subsidiary corporation of Volvo, at Volvo's option.

   e.  The termination of this Agreement for any reason shall automatically
terminate any and all agreements between Volvo and Petro franchisees for the
provision of similar services hereunder.

  30. Relationship of Petro. Petro will at all times be an independent
      ---------------------
contractor, not an agent of Volvo. Petro agrees to indemnify Volvo against, and
hold it harmless from, any liabilities, costs or expenses, including attorneys'
fees and expenses, incurred by Volvo because of any acts of  Petro or its
respective employees or agents.  Volvo agrees to indemnify Petro against, and
hold it harmless from, any liabilities, costs or expenses, including attorneys'
fees and expenses, incurred by Petro because of any acts of  Volvo or its
respective employees or agents.  Additionally, both parties agree to indemnify
and hold harmless the non-breaching party, from, any liabilities, costs or
expenses, including attorneys' fees and expenses, incurred because of a breach
this Agreement by either party.

  31. Governing Law. This Agreement will be governed by, and construed under,
      -------------
the laws of the State of North Carolina without regard to its conflicts of law
principles, except that if any provision of this Agreement would violate a
prohibition of any applicable law of any other jurisdiction, the provision will
be deemed governed by, and amended to the extent necessary to comply with, the
law of the other jurisdiction.

  32. Limitation on Damages. The damages which Volvo and Petro may recover from
      ---------------------
each other for breach of this Agreement will be limited to actual damages.
Neither of the parties may recover any consequential or other incidental,

document signed by both parties.

action.
