as shown in the Report.  If Buyer so objects to any matter (each, a "Disapproved
Matter") shown in the Report, Seller will have 30 days after receiving Buyer's

the Deposit to Buyer; and neither party will have any further obligation to the

shown in the Report that (i) is not a Disapproved Matter or (ii) is a
Disapproved Matter for which Seller has obtained the Title Company's agreement
to issue an appropriate endorsement to the Title Policy.

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

               (a) Buyer's Inspection and Testing Rights.  During the Inspection
                   -------------------------------------
Period, Buyer shall obtain a subsurface investigation report on the extent and
concentrations of any petroleum products in the soil and, if encountered,
groundwater at or under the Real Estate (the "Phase II Report").  Buyer shall
engage a geologist or professional engineer who is licensed by the State of

Consultant"), to perform the subsurface investigation and prepare and certify
the Phase II Report.  Buyer shall initially pay for the cost of the Phase II
Report.  Escrow Holder shall prorate the cost of the Phase II Report at the
closing so that Buyer and Seller share equally up to $15,000 of the total cost
of the Phase II Report.  The parties shall request that the Environmental
Consultant complete the Phase II Report at least 10 days prior to the end of the
Inspection Period.  Subject to the provisions of Section 12.7 (b) below, Buyer
shall determine the scope of work for the Phase II Report, in its reasonable
discretion.  Buyer shall have the right to modify the scope of work, as a result
of on-site conditions discovered in the course of the investigation.

               (b) Special Buyer Testing.  If Buyer requests work, or a
                   ---------------------
modification of the original scope of work, that involves any disturbance
(including any drilling or boring) of the surface of the land or any underground
vault or storage tank, underground pipes, or fuel lines ("Special Buyer
Testing"), Buyer must obtain Seller's prior written approval. Seller may
withhold its approval if it determines in good faith that the Special Buyer
Testing would interfere with Seller's business operations or would

                                       9
<PAGE>

pose a safety or environmental hazard. Buyer shall indemnify and defend Seller
from all liabilities, damages, losses, claims, costs and expenses (including
reasonable attorneys' fees) that Seller incurs arising from performance of the
Special Buyer Testing. Without limiting the immediately preceding provisions of
this Section 12.7(b), Buyer shall promptly repair any damage to the Real Estate
or any personal property located at the Real Estate resulting from any Special
Buyer Testing. But Buyer will have no liability regarding any contaminated soil
or groundwater it may discover on or under the Real Estate during the course of
the Special Buyer Testing, unless Buyer caused the release of that
contamination, for example by puncturing the underground storage tanks on the
Real Estate. Buyer's liability under this Section 12.7(b) is in addition to
Seller's right to retain the Deposit and any accrued interest on the Deposit,
when Seller is permitted to do so under any provision of this Agreement
concerning liquidated damages for Buyer's default under this Agreement. A
termination of this Agreement will not terminate Buyer's obligations under this
Section 12.7(b).

               (c) Liens.  Buyer shall keep the Real Estate free from mechanics'
                   -----
and similar liens arising from any and all Phase II Report costs (including
without limitation any Special Buyer Testing) payable by Buyer under this
Agreement.

               (d) Reports and Disclosure. Buyer shall deliver to Seller at
                   ----------------------
Seller's Environmental Notice Address a copy of the Phase II Report, within two
days after Buyer receives the report. Buyer shall not disclose the results of
any test to any regulatory agency or other third party, unless required to do so
by law and unless Buyer delivers to Seller at Seller's Environmental Notice
Address a copy of the disclosure at least ten days before Buyer mails or
otherwise transmits the disclosure to the agency or other third party.

               (e) Buyer's Termination Right.  If Buyer is not satisfied with
                   -------------------------
the environmental condition of the Real Estate, Buyer may terminate this
Agreement by giving notice of termination to Seller and Escrow Holder during the
Inspection Period. If Buyer terminates this Agreement, Buyer and Seller each
shall pay one half of the Escrow and title cancellation charges; after Buyer has
paid its share of those cancellation charges, the Deposit will be returned to
Buyer; and neither party will have any further obligation to the other under
this Agreement. But the Deposit will not be returned to Buyer until Buyer has
delivered to Seller valid, recordable waivers of mechanics' and other statutory
liens from all contractors who conducted tests at Buyer's request.

          12.8  Pending Litigation.  Seller shall indemnify and defend Buyer
                ------------------
from all liabilities, damages, losses, claims, costs, and expenses (including
reasonable attorney's fees) arising from Communities for a Better Environment v.
Tosco, Case No. 300595 (Superior Court for the County of San Francisco), based
on any discharges from the Real Estate into the soil or groundwater before
Escrow closes.

                                       10

     13.  As-Is Sale.  Buyer acknowledges that (i) it is buying the Real Estate
          ----------
solely in reliance on its own investigation; (ii) no covenants, representations,
or warranties have been made by Seller or on Seller's behalf, except those set
forth in this Agreement; (iii) Buyer has made itself aware of all governmental
laws, regulations, and requirements concerning the Real Estate or Buyer's
operation of a business on the Real Estate; and (iv) Buyer will be buying the
Real Estate in its condition existing when Escrow closes.

     14.  Seller's Right of First Refusal.  Before Escrow closes, Buyer shall
          -------------------------------
sign, have notarized, and deposit into Escrow a Right of First Refusal Agreement
(the "Right of First Refusal Agreement") in the form of the attached Exhibit
"D".

     15.  Liquidated Damages.  IF ESCROW FAILS TO CLOSE DUE TO BUYER'S DEFAULT,
          ------------------
ESTABLISHING SELLER'S ACTUAL DAMAGES CAUSED BY BUYER'S DEFAULT WOULD BE
IMPRACTICAL OR EXTREMELY DIFFICULT.  AWARDING SELLER THE DEPOSIT AND ANY ACCRUED
INTEREST ON THE DEPOSIT AS LIQUIDATED DAMAGES FOR BUYER'S DEFAULT WOULD BE
REASONABLE.  THEREFORE, SELLER'S SOLE REMEDY FOR BUYER'S DEFAULT WILL BE TO KEEP
THE DEPOSIT AND ANY ACCRUED INTEREST.  IF SELLER GIVES NOTICE TO ESCROW HOLDER
THAT BUYER HAS DEFAULTED AND INSTRUCTS ESCROW HOLDER TO PAY TO SELLER THE
DEPOSIT (IF THEN HELD IN ESCROW) AND ANY ACCRUED INTEREST, BUYER AUTHORIZES
ESCROW HOLDER TO COMPLY WITH SELLER'S INSTRUCTION WITHOUT BUYER'S FURTHER
CONSENT OR INSTRUCTIONS.

SELLER AND BUYER EACH ACKNOWLEDGE THAT IT HAS READ AND UNDERSTANDS THE ABOVE
PROVISIONS OF THIS SECTION 15; AND BY ITS INITIALS IMMEDIATELY BELOW, IT AGREES
TO BE BOUND BY THOSE PROVISIONS

     16.  Tax-Deferred Exchange.  If Seller elects to complete the sale of the
          ---------------------
Real Estate through a tax-deferred exchange under Internal Revenue Code Section
1031, Buyer shall cooperate with Seller in the exchange transaction.  Buyer's
cooperation includes the signing, acknowledgment, and delivery of all documents
that Seller reasonably requests, at no risk or expense to Buyer.  Seller shall
indemnify and defend Buyer from all liabilities, damages, claims, costs, and
expenses (including reasonable attorneys' fees) that Buyer might incur in
connection with Buyer's participation in the exchange transaction.

example, Articles of Incorporation, Bylaws., Agreement of Partnership, Limited
Liability Company Operating Agreement, or Declaration of Trust), authorizing
action (for example, corporate resolutions, consent of partners, or consent of
members), and any other document necessary to enable Seller to confirm that the

          ---------------------------------------
warrants to Buyer as follows:

          19.1  No Notices of Violation.  To Seller's actual knowledge, Seller
                -----------------------
(i) is not aware that the Real Estate violates any applicable laws (including
zoning laws), except as disclosed in Schedule 2 attached hereto and (ii) has not
received any written notice from appropriate governmental authorities that the
Real Estate violates any applicable laws (including zoning laws), except as
disclosed in Schedule 2 attached hereto.

          19.2  No Notices of Defects.  To Seller's actual knowledge, Seller (i)
                ---------------------
is not aware of any material defects in the improvements on the Real Estate and
(ii) has not received any written notice from any insurance company, board of
fire underwriters, governmental agency, or similar organization regarding any
material defects in the improvements on the Real Estate.

          19.3  No Pending or Threatened Claims.  To Seller's actual knowledge,
                -------------------------------
no litigation or claims of any kind are pending or threatened, and no facts or
circumstances exist, that may in any way materially adverse affect the Real
Estate, including material violations of regulations of the Environmental
Protection Agency or any state regulatory body concerning the disposal of
hazardous waste, petroleum, underground storage tanks, or any other hazardous
materials at the Real Estate, except as disclosed in the Environmental Documents
and Schedule 2 attached hereto.

          19.4  Construction of Improvements.  To Seller's actual knowledge, all
                ----------------------------
structures and improvements on the Real Estate (i) are in good condition,
reasonable wear and tear excepted and (ii) were constructed and installed in
substantial

                                       12
<PAGE>

compliance with all applicable laws, statutes, ordinances, codes, covenants,
conditions, and restrictions of any kind or nature affecting the Real Estate.

          19.5  Underground Storage Tanks.  The underground storage tanks and
                -------------------------
associated underground piping and vapor recovery systems at the Real Estate are
(i) fully operational and (ii) in material compliance with the December 23, 1998
underground storage tank system upgrade standards set forth under Section 25291
or Section 25292(d) and (e) of the California Health and Safety Code, and
related regulations adopted pursuant to Section 25299.3 of the California Health
and Safety Code, according to the certificate of upgrade compliance provided

"To Seller's actual knowledge" means to the actual knowledge of Kyle Christie,
Linda Cohu, Ted Harriss, or Lynn Beteag, without independent inquiry, file
review, or any investigation whatsoever.  Seller represents to Buyer that Kyle
Christie is Seller's Facility Remediation Manager assigned to the Real Estate,
Linda Cohu is Seller's Manager of Environment, Health and Safety, Ted Harriss is
the Property Management Representative assigned to the Real Estate, and Lynn
Beteag is Seller's Property Management Manager assigned to the Real Estate.  All
representations and warranties made in this Agreement will be considered to be
made on the date of this Agreement and again on the date that Escrow closes.  A
condition of Buyer's obligation to close is that all warranties and
representations made are true on the date that Escrow closes.  All those
representations and warranties will survive the Escrow closing and will not be
considered to have merged into and be governed by the closing documents for one
year after the Escrow closing.  If Buyer discovers before closing, that any
representation or warranty in this Agreement is not true, then Buyer may, as its
sole remedy, either (i) terminate this Agreement by delivering notice to Seller
before the Closing Date, in which case Escrow Holder shall return the Deposit to
Buyer, or (ii) elect to purchase the Real Estate subject to the untrue warranty
or representation, without any reduction in the Purchase Price.  If Buyer
discovers after the Escrow closing that any representation or warranty in this
Agreement is not true, Buyer may exercise all rights and remedies available at
law or in equity as a result of the untruthfulness of any representation or
warranty, as long as Buyer delivers written notice of the breach to Seller and
exercises any remedy, including the filing of any suit or other action, within
one year after the date that the Escrow closes.

           This Declaration of Environmental Restriction and Other Environmental
Covenants and Conditions (this "Declaration") dated    September 2   , 1999, is
                                                    -----------------
made by LLO-GAS, INC., a Delaware corporation ("Owner"), for the benefit of
ATLANTIC RICHFIELD COMPANY, a Delaware corporation ("ARCO").

                                   RECITALS
                                   --------

          A.  ARCO is the former owner of the real property in the County of Los
Angeles, State of California, described in the attached Exhibit "A" (the "Real
Estate").  In connection with the signing and recording of this Declaration,
ARCO conveyed the Real Estate to Owner.

          B.  By this Declaration, Owner intends to impose certain restrictions
on the Real Estate.

                                   AGREEMENT
                                   ---------

THEREFORE, Owner agrees and declares as follows:

     1.  Definitions.  Each underlined, capitalized term below has the meaning
         -----------
set forth beside it.
<PAGE>

Agency:  The environmental regulatory agency that has jurisdiction over the
------
assessment and remediation of petroleum products in soil or groundwater on or
about the Real Estate.

ARCO Entities:  ARCO's officers, directors, employees, subsidiaries, divisions,
-------------
or affiliates.

Claim:  Any liability, damage, loss, claim, suit, judgment, settlement, cost,
-----
and expense (including reasonable attorneys' fees) arising after the Effective
Date, whether or not Owner knew or suspected them to exist on the date that
Owner signed this Declaration or on the Effective Date.

Contractual Obligation:  Any obligation that ARCO may have, under the Agreement
----------------------
for Sale of Real Estate to Contract Dealer between Owner and ARCO dated

September 2, 1999 and any other written agreement entered into between Owner and
-----------
ARCO before the Effective Date, to conduct any Corrective Action on the Real
Estate.

Corrective Action:  Any assessment, monitoring, or corrective action (which may
-----------------
include natural attenuation) on petroleum products released into the soil or
groundwater at the Real Estate during gasoline station operations conducted on
the Real Estate by ARCO and the ARCO Entities before the Effective Date, to the
extent required by the Agency for gasoline station use.

Effective Date:  The date on which this Declaration is recorded.
--------------

Hazardous Material:  Any material, substance, or waste that has been determined
------------------
by any governmental authority to be capable of posing a risk of injury to
health, safety, or property.

No Further Action Letter:  A letter issued by the Agency stating that based on
------------------------
certain assumptions and conditions, the Agency will not require ARCO to perform
any further Corrective Action with respect to the Real Estate.

Pre-Closing Contamination:  Any Hazardous Material released into the soil or
-------------------------
groundwater before the Effective Date.

Restricted Area:  Each area shown on the Depiction of the Real Estate and
---------------
Restricted Area attached as Exhibit "B" and labeled "Restricted Area."

     2.   ARCO's Access Right.
          -------------------

          2.1  Grant of Access Right.  After the Effective Date, ARCO and ARCO's
               ---------------------
agents and contractors will have the unrestricted right to enter on the Real
Estate to perform any Corrective Action.  ARCO shall give Owner prior oral or
written
<PAGE>

notice of its exercise of this right to enter (the "Access Right"). In
exercising the Access Right, ARCO shall attempt to minimize, to the extent
reasonably possible, any interference with the operation of the business on the
Real Estate, except in the case of an emergency, as determined by ARCO. In
conducting its operations on the Real Estate, Owner shall attempt to minimize,
to the extent reasonably possible, any interference with any Corrective Action
by ARCO or ARCO's agents or contractors. ARCO will have sole discretion to
determine the schedule, technique, method, and design of any Corrective Action
performed by ARCO. But if the cost of two different techniques, methods, or
designs is the same, then ARCO shall select the technique, method, or design
that causes the least physical interference with the operation of the business
on the Real Estate or that takes the least amount of time to complete. Owner
shall cooperate with ARCO in obtaining Agency approval for any Corrective
Action. This Access Right includes, without limitation, (i) the right to perform
soil and groundwater investigations, (ii) the right to install, operate,
monitor, maintain, repair, close, and remove equipment (including piping and
wells) for Corrective Action, and (iii) the right to have service trucks on the
Real Estate. As part of any equipment installation, ARCO may cut and remove
portions of the asphalt and concrete. But ARCO shall patch any asphalt and
concrete that it removes with comparable asphalt and concrete. ARCO will not be
required to pay any rent or other compensation to Owner for the Access Right or
the portion of the Real Estate occupied by the equipment used in performing any
Corrective Action.

          2.2  Termination and Resumption of Access Right.  The Access Right
               ------------------------------------------
will terminate 90 days after ARCO receives a No Further Action Letter.  But if,
after the Agency issues the No Further Action Letter, the Agency requires ARCO
to perform further Corrective Action, the Access Right will resume until 90 days
after ARCO receives a new No Further Action Letter for the further Corrective
Action.  But, in all events, the Access Right will terminate 25 years after the
Effective Date.

     3.  Owner's Notification Obligations.  For 25 years after the Effective
         --------------------------------
Date, Owner shall notify ARCO within 14 days after (i) any on-site visit by the
Agency, (ii) Owner's receipt of correspondence from the Agency regarding any
Corrective Action, (iii) any release of a Hazardous Material on or about the
Real Estate requiring regulatory notification, or (iv) any activity on or about
the Real Estate that impacts ARCO's rights under this Declaration or ARCO's
performance of any Contractual Obligation.

     4.  Owner's Acceptance of the Condition of the Real Estate.  Owner
         ------------------------------------------------------
acknowledges that Pre-Closing Contamination is present on, under, or near the
Real Estate.  Owner has accepted the Real Estate, including without limitation
its environmental condition, in "AS IS" condition on the Effective Date, subject
only to any Contractual Obligation.  In addition, when the Agency issues the No
Further Action Letter, Owner will be considered to have accepted the Real Estate
in "AS IS" condition as of the date of the No Further Action Letter.  Owner
acknowledges that the purchase
<PAGE>

price paid to ARCO for the Real Estate reflects (i) the effect of this
Declaration on the Real Estate and (ii) any presence of Pre-Closing
Contamination, whether or not Owner knew or suspected it to exist on the date
that Owner signed this Declaration or on the Effective Date.

     5.  Owner's Waiver and Release of Environmental Claims.  Owner, for itself
         --------------------------------------------------
and its heirs, successors, and assigns (including without limitation all future
owners of the Real Estate), waives and releases any Claim that it might have
against ARCO or the ARCO Entities based on or related to the release or presence
of any Hazardous Material on, under, or about the Real Estate at the Effective
Date.  These Claims include, without limitation, (i) Claims that might arise
after the Effective Date and (ii) Claims that Owner did not know or suspect to
exist on the date that Owner signed this Declaration and on the Effective Date.
The waived Claims do not include any Claims arising from any material breach by
ARCO of (a) its Contractual Obligation or (b) the conditions to the Access
Right.

     6.  Real Estate Restrictions.  For a period of 25 years after the Effective
         ------------------------

         under any Restricted Area;

    (c)  Otherwise store or treat petroleum hydrocarbons on or under any

    (d)  Construct any improvements in the Restricted Area without ARCO's prior
         written confirmation that the proposed improvements will not impair
         Owner's ability to perform any Contractual Obligation.  ARCO shall not
         unreasonably withhold that confirmation.

But, as long as Owner performs the following work in compliance with all
applicable laws and governmental requirements, Owner may:

    (i)  Install asphalt or landscaping other than trees or landscape in the
         Restricted Area;

     5.  Included Rights; Exclusion of Security Interest Transfer.

Holder.  No one


                                       3
<PAGE>

other than Owner can satisfy Owner's obligation to send the Transfer Notice.
Holder may acquire the Offered Parcel that is the subject of the Tendered
Agreement, instead of the third party.

          6.2  Exercise Notice; Holder's Assessment and Testing Rights.  If
               -------------------------------------------------------

employees, contractors, and consultants may enter on the Offered Parcel to
conduct reasonable and customary environmental and other assessments and tests
of the Offered Parcel.

          6.3  Holder Indemnifies Owner.  Holder shall indemnify and defend
               ------------------------
Owner from all liabilities, damages, claims, costs, and expenses (including
reasonable attorneys' fees) that Owner incurs and that arise from Holder's
exercise of the entry right granted under Section 4.2.  But Holder will not be
liable for any decrease in the value of any Offered Parcel resulting from
Holder's discovery of any negative matter regarding the Offered Parcel,
including without limitation any contaminated soil or water existing at the
Offered Parcel before the escrow for Holder's purchase closes (the "Pre-Closing
Contamination").  Holder will not be required to remove or dispose of any Pre-
Closing Contamination.  Holder may disclose the existence of any Pre-Closing
Contamination, to the extent that Holder is required to do so under applicable
law.

     7.  Additional Purchase Terms.  If Holder's exercise of the Right is for
         -------------------------
the purchase of the Offered Parcel, the Transaction will be:  at the price and
on the other terms contained in the Tendered Agreement, but subject to the
following:

          (a)  Variation of Terms.  Owner and Holder may vary the price and
               ------------------
               other terms in any manner that is mutually acceptable to them.

          (b)  Closing Date.  Holder will have a period of time to close the
               ------------
               Transaction that is equal to the longer of (i) the period of time
               given to the third party in the Tendered Agreement, but the
               period will begin on the date of the Exercise Notice, (ii) 60
               days after the opening of Escrow, (iii) 15 days after Holder
               receives the last Appraisal Report (as defined in Section 6.3)
               that may be required under Section 6.3, or (iv) the date on which
               Holder receives notice from the applicable governmental authority
               that the authority has transferred to Holder (or an affiliate of
               Holder) any Alcoholic Beverage License that is included in the
               Business Property.

          (c)  Price Allocation When Larger Parcel or Adjacent Parcel is
               ---------------------------------------------------------
               Offered.  If (i) the Right is for the purchase of a Larger Parcel
               -------
               and (ii) the purchase price in the Tendered Agreement is
               allocated between the Real Estate and the remainder of the Larger
               Parcel, Holder


                                       4
<PAGE>

               may buy the Real Estate and not the remainder by paying only the
               consideration allocated to the Real Estate. Or if (i) the Right
               is for the purchase of a Larger Parcel and (ii) the purchase
               price is not so allocated, Holder may buy only the Real Estate by
               paying consideration that is equitable for only the Real Estate,
               considering the total purchase price to be paid by the third
               party for the Real Estate and the remainder. If Owner and Holder
               fail to agree on an equitable amount, that amount will be
               determined in accordance with Section 6. The above principles of
               this Section 5(c) will apply in like manner if the Right is for
               the purchase of the Real Estate and an Adjacent Parcel.

          (d)  Price Allocation When Business Property Is Offered.  If the Right
               --------------------------------------------------
               is for the purchase of both the Offered Parcel and any Business
               Property and Holder exercises the Right, Holder must buy both the
               Offered Parcel and the Business Property.

          (e)  Cash Instead of Delayed Payment Terms.  If the Tendered Agreement
               -------------------------------------
               provides for delayed payment terms, Holder may pay the total
               purchase price in cash at the closing of the Transaction.

          (f)  Noncash Consideration.  If the Tendered Agreement provides for
               ---------------------
               any noncash consideration, Holder may pay cash equal to the fair
               market value of the noncash consideration, as agreed to by Owner
               and Holder or, failing their agreement, as determined in
               accordance with Section 6.

     8.  Valuation Disputes.
         ------------------

          8.1  Appointing Appraisers.  If Owner and Holder cannot agree on (i)
               ---------------------
the equitable amount under Section 5(c), (ii) the value of the noncash
consideration under Section 5(f), or (iii) the fair market value under Section
8.2 or 12.9, the amount or value (the "Value") will be determined in accordance
with the appraisal procedures contained in this Section 6.  Within 15 days after
Owner or Holder receives a demand from the other for an appraisal in accordance
with this Section 6, Owner and Holder each shall appoint a Qualified Appraiser
(as defined in Section 6.2).  If one of them fails to timely appoint a Qualified
Appraiser, the Qualified Appraiser appointed by the other will determine the
Value.

          8.2  Qualified Appraiser.  "Qualified Appraiser" means a real estate
               -------------------
appraiser who (i) is a member of the Appraisal Institute, (ii) is unaffiliated
with Owner, Holder, and the third party under the Tendered Agreement, and (iii)
has had full-time experience, during each of the immediately preceding five
years, in appraising commercial real property in the area of the Real Estate.
But if Holder will be purchasing



                                       5
<PAGE>

Business Property, the Qualified Appraiser must also have had substantial
experience, during the immediately preceding five years, in appraising business
assets in the area of the Real Estate. If the Appraisal Institute ceases to
exist, a reasonably comparable, nationally recognized organization of real
estate appraisers will be substituted in the definition of Qualified Appraiser.

          8.3  Determination of Value.  If only one appraiser is appointed, the
               ----------------------
appraiser must deliver a signed report (an "Appraisal Report") to Owner and
Holder within 30 days after his appointment.  An Appraisal Report must set forth
the appraiser's determination of the Value and the considerations on which his
opinion is based.  If two appraisers are appointed and they agree on the Value,
they must deliver a signed joint Appraisal Report to Owner and Holder within 40
days after the appointment of the second appraiser.  If two appraisers are
appointed and they fail to agree on the Value, each appraiser must deliver his
signed Appraisal Report to Owner and Holder within 35 days after his
appointment.  If the lower of the two determinations is at least 95% of the
higher, the Value will be the average of the two determinations.  If not, then
within ten days after Owner or Holder requests the two appraisers to do so, they
must appoint a third appraiser who is a Qualified Appraiser.  Within ten days
after his appointment, the third appraiser must select one of the two
determinations as being the same as or the closer to the amount that he
determines as the Value; and the selected determination will be the Value.

          8.4  Appraisal Fees.  Owner and Holder each shall bear the cost of the
               --------------
appraiser that it appoints and one half of the cost of the third appraiser.

     9.  Escrow.  If Holder's exercise of the Right is for the purchase of the
         ------
Offered Parcel, the Transaction will occur through an Escrow with the Title
Company.  But if required by law or if Holder so wishes, the purchase and sale
of some or all of the Business Property will occur through a separate Escrow
with an escrow company that specializes in business property escrows and that is
acceptable to Holder.  Owner and Holder shall promptly sign escrow instructions
and open the Escrow.  Owner shall apply to the Title Company for a preliminary
title report on the condition of title of the Offered Parcel.  Despite anything
to the contrary in the Tendered Agreement or elsewhere:

          (a)  Deed and Title Insurance.  Owner shall provide the Title Company
               ------------------------
               with a deed conveying title to the Offered Parcel, free of
               encumbrances, except those that Holder elects to accept.  Owner
               shall provide Holder with an ALTA Standard Coverage Owner's
               Policy of Title Insurance insuring title, subject only to the
               printed exceptions of the policy and those encumbrances that
               Holder elects to accept.  The policy must be issued by the Title
               Company (or another insurer acceptable to Holder) and have a
               liability amount equal to the purchase price of the Offered
               Parcel.  Closing

                                       6
<PAGE>

               will be considered effected when the County Recorder accepts the
               deed for recording.

          (b)  Extended Coverage Title Policy; Survey.  Notwithstanding the
               --------------------------------------
               provisions of Section 7(a), Holder may require that the title
               policy be an Extended Coverage Title Policy.  In that event,
               Holder shall (i) obtain and provide to the title insurer any
               survey that the title insurer might require in order to issue the
               title policy as an Extended Coverage Title Policy and (ii) pay
               the increase in the premium attributable to the extended
               coverage.  Within three days after Escrow opens, Owner shall send
               to Holder a copy of the most recent survey (if any) of the
               Offered Parcel that Owner has in its possession.

          (c)  Taxes and Rent.  Taxes, rentals, and other items of income and
               --------------
               expense related to the Offered Parcel will be prorated as of the
               date that Escrow closes.

          (d)  Closing Costs.  Owner and Holder each shall pay one half of
               -------------
               Escrow Agent's fee for handling the Escrow.  Owner shall pay the
               premium for Holder's title insurance policy.  Owner and Holder
               shall pay all other closing costs in accordance with the custom
               in the County.  But if no custom exists for a particular closing
               cost, each shall pay one half of that cost.

          (e)  Deductions by Holder.  Holder may deduct from the purchase price
               --------------------
               or from any other amounts that Holder is required to pay to Owner
               in connection with the Transaction any or all of the following:
               (i) Any trade payables or other amounts that Owner or any of its
               affiliates owes to Holder or any of its affiliates with respect
               to (A) the operation of the business conducted at the Offered
               Parcel or (B) all or any part of the Offered Parcel, (ii) any
               transfer fee that Owner or any of its affiliates is required to
               pay to Holder under a Contract Dealer Gasoline Agreement, an
               am/pm Mini Market Agreement, or a SmogPros Center Agreement
               pertaining to the business conducted at the Offered Parcel, and
               (iii) the unpaid balance of principal and accrued interest on any
               loan that is payable to Holder or any of its affiliates and that
               is secured, wholly or partially, by any properly that Holder is
               buying in the Transaction, whether or not the deducted amounts
               would otherwise be due when Escrow closes.

     10.  Entity Changes.
          --------------

                                       7
<PAGE>

          10.1  Triggering Events.  Each of the following events (each, a
                -----------------
"Triggering Event") will be considered a transfer of all Offered Parcels and
Related Property that Owner owns or leases at the time of the Triggering Event:

          (a)  Change in Ownership Interests.  A sale, assignment, other
               -----------------------------
               disposition, hypothecation, encumbrance, or change in vesting of
               (i) an ownership, voting, or economic interest (including,
               without limitation, shares of stock in a corporation, a
               partnership interest in a general or limited partnership, or a
               membership interest in a limited liability company) in Owner or
               in a person that holds, directly or indirectly, an ownership,
               voting, or economic interest in Owner (a "Constituent Owner") or
               (ii) a consolidation or merger of Owner or a Constituent Owner,
               whether voluntarily, involuntarily, by operation of law, or
               otherwise;

          (b)  Disposition of Assets.  A sale, lease, assignment, or other
               ---------------------
               disposition of all or substantially all of Owner's assets; or

          (c)  Signing of Agreement.  The signing of an agreement to enter into
               --------------------
               a transaction described in Section 8.1(a) or 8.1(b).

          10.2  Exclusions from Triggering Events.  Notwithstanding anything in
                ---------------------------------
this Agreement to the contrary, none of the following events will be considered
a Triggering Event:

          (a)  Immediate Sale of Stock in Owner.  A sale of up to 25% of stock
               --------------------------------
               in Owner, within 30 days after the Recordation Date, as long as
               (i) John D. Castellucci, or a revocable trust whose trustor,
               trustee, and beneficiary are all John D. Castellucci, retains
               ownership of 75% of the stock in Owner and (ii) John D.
               Castellucci retains control of the management of Owner.

          (b)  Future Sale of Stock in Owner.  A sale of up to 15% of stock in
               -----------------------------
               Owner, as long as (i) John D. Castellucci, or a revocable trust
               whose trustor, trustee, and beneficiary are all John D.
               Castellucci, retains ownership of 75% of the stock in Owner and

               ------------------------------
               or Related Property to a parent corporation of Owner, as long as
               John D. Castellucci (i) owns 75% of the stock in the parent
               corporation and (ii) has control of the management of the parent
               corporation and retains control of the management of Owner.

                                       8
<PAGE>

          (d)  Transfer to Wholly-Owned Subsidiary.  A transfer of any Offered
               -----------------------------------
               Parcel or Related Property to a wholly-owned subsidiary of Owner,
               as long as John D. Castellucci (i) owns 75% of the stock in the
               wholly-owned subsidiary and (ii) retains control of the
               management of Owner and has control of the management of the
               wholly-owned subsidiary.

          10.3  Purchase at Fair Market Value.  Each Triggering Event will give
                -----------------------------
rise to the Right entitling Holder to buy all the Offered Parcels and Related
Property owned by Owner (i) at a price equal to their fair market value, as
agreed to by Owner and Holder or, failing their agreement, as determined in
accordance with Section 6, and (ii) on any other applicable terms contained in
any agreement to enter into the Triggering Event.

          10.4  Rescission by Holder.  If the entire purchase price for a
                --------------------
purchase by Holder in accordance with Section 8.3 results from one or more
Values determined in accordance with Section 6, Holder may rescind its Exercise
Notice by giving a notice of rescission to Owner.  If only part of the purchase
price for a purchase by Holder in accordance with Section 8.3 results from one
or more Values determined in accordance with Section 6 and that part of the
purchase price is greater than 15% of the entire purchase price, Holder may
rescind its Exercise Notice by giving a notice of rescission to Owner.  The
notice of rescission must be given within ten days after Holder receives the
last Appraisal Report that may be required under Section 6.3.  If Holder
rescinds its Exercise Notice, Holder shall pay the cost of all the appraisers.

     11.  Environmental Indemnification.  If Holder acquires an Offered Parcel
          -----------------------------
covered by a Transfer Notice or if Holder acquires the Real Estate in accordance
with Section 12, the person transferring the Offered Parcel or the Real Estate
to Holder ("Transferor") shall sign and deliver to Holder through the Escrow an
indemnification agreement containing the following provision:

          Transferor shall indemnify and defend Holder from all claims,
          liabilities, damages, losses, costs, and expenses (including
          reasonable attorneys' fees) that Holder incurs arising from any
          environmental contamination occurring or hazardous materials existing
          at the real property that Transferor is concurrently conveying to
          Holder (the "Real Property"), to the extent that the contamination or
          hazardous materials (i) are present at concentrations that any
          governmental agency will require to be remediated or otherwise are not
          in compliance with all applicable statutory and regulatory
          requirements, (ii) are known or discovered before Holder begins its
          operations at the Real Property, and (iii) are not those on which
          Holder is obligated to


                                       9
<PAGE>

          perform any corrective action under a written agreement between
          Transferor and Holder. This agreement to indemnify and defend will
          survive the closing of Transferor's transfer of the Real Property to
          Holder.

     12.  Owner's Transfer Rights; Notice of Changed Terms.  If Holder does not
          ------------------------------------------------
exercise the Right for a transaction covered by a Transfer Notice, Owner may
then transfer the interest in the Offered Parcel and any Related Property to the
third party but (i) only for the price and on the other terms contained in the
Tendered Agreement; (ii) only to the third party named in the Tendered
Agreement; (iii) only within 120 days after Holder receives the Transfer Notice;
and (iv) subject to Holder's rights under this Agreement, which will continue
with respect to each future intended transfer of an Offered Parcel by any owner
or tenant of the Real Estate.  Any change in (i) the identity of the third party
or the ultimate beneficial owner of the third party or (ii) the price or other
terms of the Tendered Agreement will give rise to a new Right exercisable by
Holder; and Owner must notify Holder of the changes.  Owner's notice must
include a copy of any signed document changing the price or other terms of the
Tendered Agreement.

     13.  Survival of Holder's Rights.  Holder's failure to exercise the Right
          ---------------------------
with respect to a Tendered Agreement covered by a Transfer Notice will not
relieve Owner from the obligation to comply with this Agreement in connection
with any later Tendered Agreement that Owner enters into during the Right
Duration.  Holder may void any transfer that Owner makes without complying with
this Agreement.  To exercise this right to void a transfer, Holder must give an
Exercise Notice within 25 days after Holder receives actual notice of the
intended or consummated noncomplying transfer and the complete terms of the
transfer.

Policy; and (iii) Holder and Lender shall sign, acknowledge, and deliver any
other documents necessary or appropriate to consummate the transaction.  The
Assignment Endorsement must insure Holder against loss or damage sustained be
reason of lack of priority of the Lien over defects, liens, or encumbrances
other than those shown in Lender's Title Policy and those that Holder approves
in its sole discretion.

          14.8  Holder's Purchase of Elected Property.  If Holder elects to buy
                -------------------------------------
the Elected Property, the purchase and sale transaction will be consummated in
accordance with the procedures described in Section 7.  Holder will have a
period of time to close the purchase of the Elected Property that is equal to
the longer of (i) 60 days after the opening of Escrow, (ii) 15 days after Holder
receives the last Appraisal Report that may be required under Section 6.3, or
(iii) the date on which Holder receives notice from the applicable governmental
authority that the authority has transferred to Holder (or an affiliate of
Holder) any Alcoholic Beverage License that is included in the Elected Property.

          14.9  Purchase Price for Elected Property; Reduction and Credits.  The
                ----------------------------------------------------------
purchase price for the Elected Property will be equal to 80% of the fair market
value of the Elected Property, as agreed to by Owner and Holder or, failing
their agreement, as determined in accordance with Section 6.  But the purchase
price will be reduced by the total costs (including attorneys' fees) that Holder
incurs in connection with the purchase and sale of the Elected Property, to the
extent that those costs exceed the costs that Holder would have incurred if
Holder had purchased the Elected Property after Holder's exercise of the Right
with respect to a Tendered Agreement for Owner's sale of the Elected Property.
If Holder elects to buy the Elected Property subject to the Lien that was the
subject of the Lien Enforcement Notice, Holder will receive a credit against the
purchase price for the Basic Loan Balance as of the date that Escrow closes.  If
Holder elects to buy the Elected Property subject to a lien that secures a
monetary obligation other than the Secured Obligation that was the subject of
the Lien Enforcement Notice, Holder will receive a credit against the purchase
price for the unpaid balance of that monetary obligation as of the date that
Escrow closes.

          14.10  Buying Subject to the Lien.  If Holder elects to buy the Real
                 --------------------------
Estate in accordance with this Section 12, Holder may buy the Real Estate
subject to the Lien and without assuming the obligations secured by the Lien.
Additionally, any person who later buys the Real Estate from Holder may buy the
Real Estate subject to the Lien and without assuming the obligations secured by
the Lien.

          14.11  Reinstating the Secured Obligation.  If Holder becomes the
                 ----------------------------------
owner of the Real Estate in accordance with this Section 12, Holder may
reinstate the Secured

                                      13
<PAGE>

Obligation within 30 days after Holder becomes the owner of the Real Estate by
paying the Reinstatement Amount as of the reinstatement date. Within seven days
after the reinstatement date, Lender shall credit the unpaid balance of the
Secured Obligation by the Default Amounts.


          14.12  No Prepayment Penalty.  At any time after Holder reinstates the
                 ---------------------
Secured Obligation, Holder or any person who later buys the Real Estate from
Holder may prepay all or any portion of the unpaid balance of the Secured
Obligation without the imposition of a prepayment penalty.

          14.13  Lender's Transfer Rights; New Lien Enforcement Notice.  If
                 -----------------------------------------------------
Holder does not exercise the Foreclosure Purchase Right, Lender may proceed with
the enforcement of the Lien and (i) sell the Encumbered Property to a third
party at a Foreclosure Sale, (ii) buy the Encumbered Property by a credit bid at
the Foreclosure Sale, or (iii) accept a deed conveying the Encumbered Property
in lieu of foreclosure, in each case without the requirement of making a further
offer of the Encumbered Property to Holder.  But if, within one year after
Holder actually received the Lien Enforcement Notice, Lender's enforcement of
the Lien has not been completed or Lender has not accepted a deed in lieu of
foreclosure, Lender must give a new Lien Enforcement Notice to Holder before
completing the enforcement of the Lien or accepting a deed in lieu of
foreclosure.

          14.14  Holder's Rights Bind Foreclosure Purchaser.  If Holder does not
                 ------------------------------------------
exercise the Foreclosure Purchase Right and (i) Lender or a third party buys the
Encumbered Property at the Foreclosure Sale or (ii) Lender accepts a deed
conveying the Encumbered Property in lieu of foreclosure, the new owner of the
Encumbered Property will acquire the Real Estate subject to Holder's rights
under this Agreement, which will continue with respect to each future intended
transfer of an Offered Parcel by any owner or tenant of the Real Estate.

                                    GENERAL PROVISIONS

extended for the period during which the party is prevented from performing by
an event beyond its reasonable control (including, without limitation, acts of
God, work stoppage, riots, and other similar events) (an "Uncontrollable
Event").  If (i) a party who has the right to exercise a right under this
Agreement has not done so by the last date allowed under this Agreement and (ii)
on that date, the party is prevented from exercising the right due to an
Uncontrollable Event, the date will be extended until the third business day
after the Uncontrollable Event ends.

     G6.  Entire Agreement; Modification; Waiver.  This Agreement (including any
          --------------------------------------
attached Exhibits) contains the entire agreement between Owner and Holder with
respect to the Right granted under this Agreement.  Any modification of this

          -------------
this Agreement.

     G8.  Interpretation.  The captions appearing in this Agreement are for
          --------------
convenience of reference only, and they do not affect the meanings of the
provisions of this Agreement.  In this Agreement, each gender includes the other
genders.  Words in the singular include the plural and vice versa, when
appropriate.  The word "person" includes natural individuals and all other
entities.  The word "cost" includes any cost or expense.  The word "term"

that is part of an agreement.  Whenever a provision of this Agreement requires
Owner or Holder to perform an act, that person must do so at its sole cost
(unless otherwise stated in connection with that provision).

     G9.  Attorneys' Fees.  If a dispute arises with respect to this Agreement
          ---------------
and if Holder prevails in the dispute, then Holder will be entitled to recover
