          construed so as to require only the consent of that Seller, or those
          Sellers, with an interest in the subject matter requiring consent.

          matter or which is not the owner of the property/operation/stock for
          which consent is required. If there is more than one Seller, Principal

     leases attached as Exhibits "F-1" & "F-2."  Buyer and Seller shall

     cooperate in obtaining each lessor's consent to transfer leased premises to
     Buyer.

     D.   Fee Simple Interests in Real Property, if any, shall be transferred
     free and clear of all title defects and objections, security interests,
     liens, claims, charges and encumbrances of any nature whatsoever.  All Fee
     Simple Interests in Real Property are set forth on the attached Exhibit "G"
                                                                     -----------

          Seller's Property and Seller's Improvements, including, without
          limitation, any right, title and interest of Seller in and to adjacent
          streets, alleys or rights-of-way.

                           Amount of Purchase Price

II   A.   The total "Purchase Price" set forth in BPI Item 7 is based on the
     earnings before interest taxes, depreciation and amortization ("EBITDA").
     The EBITDA shown in BPI Item 8 and the "Effective Capitalization (`Cap')
     Rate" in BPI Item 9, represents the sum of the purchase prices for all the
     operations to be purchased, all personal, real and intangible assets (other
     than Inventory), personal and corporate covenants not to compete, and the
     guaranties contemplated herein.  "Allocations" of the purchase price for
     each operation and for the Covenants Not to Compete are shown  on BPI Item
     10.  Inventory (which includes Seller's stock of gasoline, oil, lubricants,
     filters, detergents, parts,
<PAGE>

     accessories and supplies) will be purchased at Seller's actual cost to
     third parties (excluding Sellers' overhead and operating expenses).
     Notwithstanding the foregoing, Buyer shall have no obligation to purchase
     slow-moving or obsolete items carried by Seller as inventory.

     B.   The purchase price includes the physical assets in their condition at
     the time of sale, without further adjustment.  Buyer and Seller acknowledge
     that the amount allocated to each asset represents its fair market value
     determined pursuant to an arm's-length negotiation. They further
     acknowledge that a tax attorney, accountant, or other qualified advisor has
     explained the tax consequences of the allocations to them. Buyer and Seller
     each agree to report the sale of the operations for federal income tax
     purposes in accordance with the allocations set forth in this Agreement.

                    Payment of Purchase Price & Commissions

III  A.   The purchase price for each Covenant Not to Compete is included in the
     Purchase Price and shall be disbursed at close of escrow.

     B.   The purchase price for each of the operations purchased is payable in
     cash at close of escrow, less a "Hold-Back Percentage" specified in BPI
     Item 11 of the total purchase price (operations and Covenants).  The hold-
     back shall be in effect for the Hold-Back Period specified in BPI Item 12.
     To the extent that the hold-back is depleted during the hold-back period by
     the "Hold-Back Depletion Amount" specified in BPI Item 13, or more, Seller
     shall immediately deposit sufficient funds to bring the amount held-back to
     its original level.  Although the hold-back will terminate at the end of
     the Hold-Back Period, the guarantees, warranties and representations for
     which the hold-back was security, remain in effect for the "Guaranty
     Period" specified in BPI Item 14, further extended by the time during which
     a lawsuit could be brought relating to these items or, if a lawsuit or
     other legal proceeding has been commenced, until the final decision in such
     suit or proceeding.  If a lawsuit or other legal proceeding is instituted
     during the Hold-Back Period, the funds shall not be released but shall be
     held until the final decision in such suit or proceeding.  During the Hold-
     Back Period, the funds held back shall be in an escrowed deposit, in an
     interest-bearing  account in one or more financial institutions approved by
     both Buyer and Seller.  Risk of loss of funds while on deposit shall be
     with Seller and Seller shall receive all of the interest paid by each such
     institution while on deposit.  Loss of funds shall in no way relieve Seller
     of its obligations hereunder and Seller represents and warrants that it has
     sufficient funds to meet its obligations.

     C.   Buyer shall notify Seller and the manager of the escrowed account
     promptly upon receipt of notice that a claim has been made with respect to
     an item for which the hold-back is security.  Seller shall have five (5)
     days to object to disbursement of hold-back funds to pay the claim.
     Objection must be in writing and state Seller's reasons for objecting. If
     no reason has been stated or if Seller has not objected, disbursement in
     accordance with Buyer's instructions shall be made immediately without any
     need for instructions from Seller with respect thereto.  If Seller has
     objected, on a reasonable basis, and has brought suit, within 30 days of
     notice to Seller of the claim, to challenge the claim, Seller shall
     deposit the amount in dispute with the court, pending the final disposition
     of the lawsuit.  Seller shall be liable to Buyer for all detriment suffered
     by Buyer during the pendency of the lawsuit.

     D.   Buyer and Seller have utilized the respective services, if any, of
     those brokers, agents or finders listed in "Buyer's Broker" BPI Item 15 and
     "Seller's Broker" BPI Item 16 in connection with the
<PAGE>

     sale of the assets relating to this Agreement. Each party agrees to pay its
     Agent's fee, at close of escrow, pursuant to their separate agreements with
     their Agents. Each party shall indemnify and hold the other party harmless
     from any and all claims, expenses, demands, actions and costs thereof
     arising in connection with this transaction to an Agent other than that
     Agent specified in the BPI as that party's agent. Each party represents and
     warrants that it has not employed any brokers or other representatives with
     respect to this transaction and that if any brokers or finders make such a
     claim, the employing party shall be solely responsible for any fees,
     commissions, claims, expenses, demands, actions and costs thereof, with
     respect thereto.

                       Documents and Physical Inspection

IV   Seller shall immediately, or as soon as reasonably possible after the
     effective date hereof, deliver to Buyer the following "Inspection Items":

     includes Seller Lands and/or operations).

     C.   Architectural drawings, plans and specifications as are available to
     Seller for the improvements on each Seller's Property.

     D.   Two (2) copies of a current ALTA survey for each of the Seller's Lands

     E.   Current financial statements for all tenants, if any, on each Seller's

     F.   Tax returns, operating and other financial statements, prepared in-
     house, or otherwise, for each Seller's Property for the three (3) most
     recent fiscal years. Seller agrees to allow Buyer or Buyer's agent to have
     access at Seller's applicable places of business and operations at
     reasonable times and hours to inspect, copy as needed at Buyer's expense,
     and audit Seller's files and records relating to the operations and to
     Seller's Property.

     G.   Certificates of Occupancy for each Seller's Property.

     H.   A current Zoning Certificate for each Seller Property, which Seller
     agrees shall be completed by the applicable governing municipalities to
     include the same terms and be in the same form and content as the Zoning
     Certificate attached hereto as Exhibit "I". Buyer will take steps to obtain
                                    -----------
     this item, or otherwise confirm the zoning, and Seller will cooperate as
     necessary.
<PAGE>

     I.   Current tax receipts and insurance certificates for each Seller's
     Property.

     J.   UCC searches of each Seller and Principal,  in the county and state

     L.   Other documents or reports reasonably required by Buyer in order to

                                    Escrow

V    A.   Escrow ("escrow") shall be opened with the "Escrow Company" specified
     in BPI Item 18, upon execution of this Agreement.  If this Agreement has
     not been fully executed and escrow has not opened by the "Escrow Opening
     Date" specified in BPI Item 19, this Agreement shall terminate and neither
     party shall have any further obligation to the other.  This Agreement shall
     operate as the basis for escrow instructions, with the understanding that
     additional form instructions as required by escrow, which do not conflict
     with this Agreement, shall be executed by the parties.  In the event of any
     differences between this Agreement and the escrow instructions, this
     Agreement shall prevail. The deposit of this fully executed Agreement, by
     either party, with escrow shall be deemed the opening of escrow, regardless
     of the date escrow forms are signed by the parties.

     B.   Escrow shall take appropriate action to comply with bulk sales laws.
     Seller shall be solely responsible for all sales, use and transfer taxes.

     C.   Each party shall pay its own attorney's fees.  Escrow fees shall be
     split equally by the parties, except for extraordinary costs which are for
     the benefit, or at the sole request, of one party. Buyer shall deposit the
     sum, specified as the "Initial Deposit" in BPI Item 20, in escrow within 10
     days of escrow's opening.  Escrow shall immediately deposit said sum in an
     escrowed interest-bearing account.  Interest from the sum so deposited
     shall be credited to Buyer until the last of the following: Buyer withdraws
     from the escrow, escrow closes, or the Initial Deposit becomes non-
     refundable.  The interest so credited shall be used either to reduce the
     amount of Buyer's final deposit or shall be returned to Buyer if Buyer is
     entitled to a return of the Initial Deposit.  After the number of "Days
     from Opening" specified in BPI Item 21 and provided that Seller has
     provided each and every item required by Buyer from Seller to complete its
     due diligence in accordance with the checklist provided by Buyer to Seller
     and provided each such item is provided within a time period which will
     allow Buyer to complete its due diligence, and provided Seller has not been
     notified of disapproval by

     Buyer of any element of the sale or that Buyer's contingencies have been
     satisfied or removed, the Initial Deposit in escrow will become non-
     refundable.

     Notwithstanding the preceding, the Initial Deposit again becomes refundable
     if, at any time, including after the number of "Days from Opening," any of
     the following occur:
<PAGE>

          (1)  Purchase of land or change in lease terms are a condition of this
          Agreement and such purchase or change does not occur;

          (2)  Buyer disapproves of the state of Title or the ALTA survey;

          (3)  Buyer disapproves of the Phase I's or Phase II's;

          (4)  Information, financial and otherwise, supplied by Seller to Buyer
          is inaccurate; or

          (5)  Escrow fails to close and Buyer is not at fault therefor.

     At any time prior to the Initial Deposit becoming non-refundable, or upon
     written disapproval of the Phase I's or Phase II's, Buyer may withdraw from
     the escrow with no penalty or obligation to Seller.  Buyer shall be under
     no obligation, and it shall not be deemed Buyer's fault if Buyer does not
     close escrow because of a failure of any condition in this Agreement.
     Further, notwithstanding the lack of obligation to close escrow upon a
     failure of a condition, it is specifically acknowledged by the parties that
     each and every condition required by Buyer is for Buyer's benefit only and
     Buyer has the absolute right to waive one or more or all conditions
     precedent, in Buyer's sole discretion, and proceed with close of escrow.

     If escrow fails to close due to fault of Buyer, the Initial Deposit is
     agreed to be LIQUIDATED DAMAGES and each party shall initial here to show
     their acceptance of this provision: ________________________[INITIAL HERE].
     If escrow fails to close due to the fault of Seller, or if Seller attempts
     to withdraw from escrow at any time after escrow has opened, as defined
     herein, Buyer shall have the right to any and all remedies available at law
     or in equity, including, but not limited to, an action for specific
     performance or a declaratory judgment with respect to this Agreement.

     D.   All personal property taxes applicable to the assets shall be prorated
     on a reasonable basis between Buyer and Seller as of the closing.  Buyer
     and Seller agree to make payments to each other as of the closing, to the
     extent necessary to assure that both parties are reimbursed for the amount
     of any personal property taxes that arise with respect to time periods
     during which the assets were owned by the other party.

     E.   The balance of the Purchase Price, adjusted for allocations or credits
     as set forth in this Agreement, shall be deposited  prior to the scheduled
     closing date.  The price payable for Inventory shall be added to the
     purchase price.  Upon Closing, the Initial Deposit, together with all
     interest accrued thereon, shall be applied as a credit to the Purchase
     Price.

     harmless from and against any liabilities, obligations, claims, damages,
     costs and expenses (including attorneys' fees) associated with or arising

               Is" by giving written notice to the Seller of the same and close

IX   A.   Until the Closing, to the extent covered by Insurance, Seller shall

     condemned by an applicable governmental authority prior to Closing, Buyer
     shall have the right to exercise one of the following options: (1)
     terminate this Agreement in its entirety by giving written notice to Seller
     within ten (10) days after Buyer receives notice of said condemnation from
     Seller in which event this Agreement shall become null and void; or (2)
     Buyer may accept Seller's Property in its condemned state, "As Is," and
     proceed to close on Seller's Property according to the remaining terms of
     this Agreement.  In this event, Buyer shall be entitled to all the proceeds
     awarded relating to said condemnation.

     request, such employees, and Seller shall pay all outstanding wages,

                                     Taxes

XIII  For purposes of this Agreement "Taxes" means any federal, state, local or

      Closing Date. All such Returns are accurate and complete and were prepared
      in conformity with all applicable laws and regulations. Seller has duly
      paid in full all Taxes shown to be due on such Returns or otherwise
      assessed against Seller, and has made adequate provision (by the

      arising in connection with any tax period ending on or before the Closing
      Date. There are no tax liens upon the assets. There are no outstanding
      agreements or waivers by Seller for the extension of time for the
      assessment of any Taxes. Seller is not a party to any pending action or
      proceeding by any governmental authority for the assessment or collection
      of any Taxes, and no claim for assessment or collection of any Taxes has
      been asserted against Seller that has not been paid. There are no pending
      or threatened audits, investigations, or claims for or relating to any
      liability regarding Seller's obligations to pay Taxes. Seller shall be
      solely liable and responsible for all of Seller's Taxes, and hereby agrees
      to completely and unconditionally indemnify, defend and hold Buyer
      completely harmless from and against any liabilities, obligations, claims,
      damages, costs and expenses (including attorneys' fees) associated with or
      arising out of Seller's Taxes.

                    Confidentiality of Agreement/Publicity

XIV   The terms and conditions of this Agreement are and shall at all times
      remain confidential, both before and after Closing, and before and after
      any termination hereof. No provision of this Agreement shall be disclosed
      by any party without the prior written consent of all of the other
      parties. All publicity concerning the transactions contemplated by this
      Agreement shall be jointly planned and coordinated
<PAGE>

      publicity regarding the transactions contemplated by this Agreement
      without the prior written consent of the other parties. Any consents
      requested or otherwise required pursuant to this Section XV shall not be
      unreasonably withheld by any party.

      prior to Closing, Seller and those Principals designated by Buyer, and any
      other individuals or companies listed in BPI Item 3 shall execute and
      deliver respective non-competition agreements in the form of Exhibits
                                                                   --------
      "N-1- Non-Competition-Corporate" and "N-2-Non-Competition-Individual" to
      -------------------------------     --------------------------------
      this Agreement (collectively "Non-Competition Agreements" and individually
      "Non-Competition Agreement-Corporate," and "Non-Competition Agreement-
      Individual"). As additional consideration for this Agreement and pursuant
      to their respective Non-Competition Agreements, Seller and Principals
      agree that they shall not directly or indirectly compete with Buyer or
      carry on or engage in the operation of a car wash within the "Non-Compete
      Area" for the "Non-Compete Period" each of which is specified in BPI Item
      25.

                         Indemnity/Guaranty Agreements

XVI   Except as otherwise expressly provided in this Agreement, Seller and
      Principals shall indemnify Buyer and hold Buyer's property, including the
      property described in this Agreement, harmless from any and all expenses,
      claims, losses, damages, injuries, and liabilities ("Loss") arising from
      or on account of Seller's operations or Seller's lease or ownership of any
      of the property described in this Agreement. Seller and Principals shall
      execute Guaranty Agreements as set forth in Exhibit "O."
                                                  -----------

                  Introduction to and Retention of Customers

XVII  Pending the closing, Buyer shall have the right, during normal business
      hours, at times, and under conditions agreed upon by Seller, to frequent
      the locations where Seller conducts its operations. Seller shall use its
      best efforts to introduce Buyer to Seller's customers and others with whom
      Seller does business in connection with its operations, as Seller's
      successor to the practice. Seller shall, in every manner encourage its
      present and former customers and suppliers to frequent Buyer's operations
      or otherwise conduct business with Buyer.

                            Ownership of Equipment

XVIII All of the equipment is owned by the companies listed as Seller. Seller
      represents that none of the equipment is leased.

                              Amendments/Waivers

XIX   This Agreement may be amended, supplemented, modified or rescinded only
      through an express written instrument signed by all the parties or their
      respective successors and assigns. Either party may specifically and
      expressly waive in writing any portion of this Agreement or any breach
      hereof,
<PAGE>

     but no such waiver shall constitute a further or continuing waiver of any
     preceding or succeeding breach of the same or any other provision. The
     consent by one party to any action for which such consent was required
     shall not be deemed to imply consent or waiver of the necessity of
     obtaining such consent for the same or similar acts in the future. All
     remedies, rights, undertakings, obligations and agreements contained in
     this Agreement shall be cumulative, and none of them shall be in limitation
     of any other remedy, right, undertaking, obligation or agreement of any
     party, except as set forth in the liquidated damages clause. The failure by
     any party hereto at any time to enforce any of the provisions of this
     Agreement, or to require at any time performance of any of the provisions
     hereof, shall in no way be construed to be a waiver of such provisions or
     to affect either the validity of this Agreement or the right of any party
     to thereafter enforce each and every provision of this Agreement. UNDER NO
     CIRCUMSTANCES SHALL A GUARANTOR HAVE THE RIGHT TO APPROVE, NOR SHALL THERE
     BE ANY NEED FOR APPROVAL OF, ANY WRITTEN MODIFICATION OF THIS AGREEMENT OR
     ANY AMENDMENTS HERETO.

                               Attorneys' Fees

XX   In the event that any party  brings a legal action or proceeding to enforce
     the obligations of this Agreement or to exercise any of its rights or
     remedies, or if any party is required to defend the validity or
     enforceability of the obligations of this Agreement in any action or
     proceeding, the prevailing party shall be entitled to an award of its
     attorneys' fees and costs and expenses incurred in bringing or defending
     the action or proceeding, regardless of the forum in which the resolution
     is determined and regardless of whether such legal action is prosecuted to
     judgment.
<PAGE>

                                    Notices

XXI    Notices shall be written and deemed given when personally delivered or 3
       days after deposit in the U.S. Mail, registered or certified, return
       receipt requested, or on date signed for when sent by expedited mail or
       courier service where receipt can be confirmed, and addressed to the
       parties or guarantors at their respective addresses specified in BPI Item
       26, subject to change by written notice. Notices may also be given and
       will be effective as of the first business day following the date of
       transmission if (i) sent over electronic transmitting devices, such as
       facsimile, Telex, telecopy machines, and computers; (ii) the party to
       whom the notice is being sent has such a device in its office and (iii) a
       complete copy of any notice so transmitted shall have also been mailed in
       the same manner as required for a mailed notice. Avoidance of or refusal
       to accept service shall be deemed acceptance.

                                Time of Essence

XXII   Time is of the essence with respect to the performance of each party's
       obligations hereunder.

                                 Severability

XXIII  In the event that any provision of this Agreement becomes or is declared
       by a court of competent jurisdiction to be illegal, unenforceable or
       void, then this Agreement shall continue in full force and effect without
       said provision. Provided, however, that no such severability shall be
       effective if it materially changes the economic benefit of this Agreement
       to any party.

                                   Exhibits

XXIV   All exhibits and addenda described in this Agreement and the BPI are
       incorporated herein by reference as if fully set forth herein, and
       constitute a material part of this Agreement. The parties hereby
       specifically approve the form and substance of any such exhibits and
       addenda. In the event of any conflict between the provisions of this
       Agreement and the provisions of any such exhibits and addenda, the
       provisions of such exhibits and addenda shall govern.

                  Diligence, Good Faith and Further Documents

XXV    The parties specifically agree to act diligently, in the utmost good
       faith and in a timely manner to perform their respective obligations
       pursuant hereto, and to carry out the reasonable intent of the provisions
       of this Agreement. Each of the parties agrees to cooperate in good faith
       with the other, and to execute and deliver such further instruments and
       perform such other acts as may be reasonably necessary or appropriate to
       consummate and carry into effect the transactions contemplated by this
       Agreement.
<PAGE>

                                 Survivability

XXVI   All of the representations and warranties of Seller and Principals
       pursuant to this Agreement and the Other Documents shall survive the
       Closing.

                               Entire Agreement

XXVII  This Agreement constitutes the entire understanding between Buyer and
       Seller concerning its subject matter and all representations, agreements,

       oral or written, have been fully merged herein and are superseded hereby,
       except to the extent fully executed management contracts have been
       previously entered into between Seller/Principals and Buyer. Any
       agreements, representations, letters, conversations, or proposals
       respecting the operations or the sale of assets not expressly set forth
       in this Agreement shall have no effect except for a subsequent written
       modification signed by the party to be charged.

                             Assignment Prohibited

XXVIII Neither this Agreement, nor any interest herein, shall be assignable
       (voluntarily, involuntarily, by judicial process or otherwise) by any
       party hereto to any person or entity without the prior written consent of
       the other executing party. Any attempt to assign this Agreement without
       such consent shall be void. Notwithstanding the above, Seller may assign
       any and all rights to receipt of payments.

                                  Successors

XXIX   Subject to the foregoing section, this Agreement shall be binding upon
       and inure to the benefit of the parties and their respective heirs,
       legatees, legal representatives, successors and permitted assigns.

       the internal laws of the State shown in BPI Item 27, "Governing State

       dispute, action, litigation or other proceeding concerning this Agreement
       shall be instituted, maintained, heard and decided in the county shown in
       BPI Item 28, "County Jurisdiction."

                                 Counterparts

XXXI   This Agreement may be executed in any number of counterparts, each of
       which shall be deemed to be an original, but all of which together shall
       constitute one and the same instrument and agreement.
<PAGE>

                                   Remedies

XXXII  All rights, remedies, undertakings, obligations, options, covenants,
       conditions and agreements contained in this Agreement shall be cumulative

       performing any of Seller's obligations under this Agreement for any
       reason, or if any of the representations or warranties of Seller herein
       are untrue at Closing, Buyer may, at its option, either terminate this
       Agreement or seek to enforce specific performance of this Agreement.

       Agreement. "Shall" or "will" as used herein is mandatory. "May" is not

    Re: Millennia Purchase - Quaker Car Wash, Inc.
        ------------------------------------------

    Dear Patrick:

    It is my understanding that you and Reed Fisher discussed an extension of
    the escrow this morning. As you know, Millennia Car Wash, LLC ("Millennia")
    has the absolute right to cancel the Purchase and Sale escrow and receive a
    return of the Millennia monies held therein. As you also know, Millennia
    prefers not to cancel the escrow. Therefore, Millennia hereby notifies you
    that Millennia will refrain from exercising its right to cancel and demand
    return of its monies today, specifically conditioned on your agreement to
    (i) extend the date in BPI Item 21 - Days From Opening (Earliest Date On
    Which Buyer's Deposit Becomes Non-Refundable) to December 29, 1998 and (ii)
    extend the date in BPI Item 24 - Date for Close of Escrow - to not later
    than March 2, 1999.

    In order to accept this offer to refrain from canceling escrow immediately,
    Seller must indicate its acceptance by signing below. Further, a copy of
    this signed letter must be returned by FAX to me at 949-498-7772 and to
    Millennia at 760-635-0578 today, and the original sent via FedEx or other
    expedited service for delivery tomorrow, if possible, otherwise the
    following day. The FedEx should be sent to the Millennia offices at 511
    Encinitas Blvd., Suite 100, Encinitas, CA 92024, Attention: Carrie Tonini.
    In the absence of Seller's agreement and receipt of evidence thereof, this
    letter shall serve as notification that the escrow is canceled. I will be
    out of my office tomorrow, making time extremely short. If any signature
    lines have been overlooked, please add a signature sheet as necessary.

    Except as stated above, Millennia is not waiving, relinquishing, or
    modifying any rights or privileges whatsoever.

    As Reed has already told you, if you desire more information concerning the
    proposed extension, Stephen Prior is at the Millennia offices (phone
    760-635-0492) today and should be able to assist you.

Dear Patrick:

In accordance with Steve Prior's discussion with you earlier this week, I
understand that there is agreement to amend the escrow as follows:

IN CONSIDERATION of the mutual promises of the parties, Buyer and Seller agree
as follows:

1.   As between Buyer and Seller, Buyer has the option, but not the obligation,
     to assign all or any part of its interest in the Agreement as amended,
     and the escrow for the consummation thereof, to American Wash Services,

     assignment of its interests to AWS. All other agreements and amendments
     contained herein are for the benefit of AWS, Issuer, and Seller, as their

          Issuer to deliver the Issuer's Stock, each Seller represents and
          warrants as follows:

               (a)   Seller is a Texas corporation and each Seller is an
               accredited investor as that term is defined in Regulation D under

               (b)   Each Seller represents and warrants that the Issuer's Stock
               is being acquired for its own account without a view to public
               distribution or resale and that Sellers have no contract,

               (c)   Each Seller represents and warrants that in determining to
               acquire the Issuer's Stock, it has relied solely upon its
               independent investigation, including the advice of its legal
               counsel and accountants or other financial advisors or purchaser
               representatives, and has, during the course of

               discussions concerning its acquisition of the Issuer's Stock,

               such documents concerning Buyer and its business and affairs as
               each Seller has requested so as to more fully understand the
               nature of the investment and to verify the accuracy of the
               information supplied.

               (d)   THE SELLERS ACKNOWLEDGE THAT THE ACQUISITION OF THE
               CONSIDERATION STOCK INVOLVES A HIGH DEGREE OF RISK, and represent
               and warrant that they can bear the economic risk of the Seller's
               acquisition of the Issuer's Stock, including the total loss of
               the investment.

               (e)   The Sellers represent and warrant that (i) they have
               adequate means of providing for their current needs and financial
               contingencies, (ii) they have no need for liquidity in this
               investment, (iii) they have no debts or other obligations, and
               cannot foresee any other circumstances that are likely in the
               future to require them to dispose of the Issuer's Stock, and (iv)
               all their investments in and commitments to non-liquid
               investments are, and after acquisition of the Issuer's Stock will
               be reasonable in relation to their net worth and current needs.

               (f)   The Sellers understand that no federal or state agency has
               approved or disapproved the Issuer's Stock or made any finding or
               determination as to the fairness of the Issuer's Stock for
               investment.

               (g)   The Sellers understand that the Issuer's Stock is being
               offered and sold in reliance on specific exemptions from the
               registration requirements of federal and state securities laws
               and the Buyer is relying upon the truth and accuracy of the
               representations, warranties, agreements, acknowledgments and
               understandings set forth herein in order to determine the
               applicability of such exemption and the suitability of Sellers to
               acquire the Issuer's Stock.

               (h)   The Sellers represent and warrant that they are familiar
               with the business and financial affairs of the Seller corporation
               and have had access to all financial statements prepared by the

Re: Millennia/AWS/Mace Purchase - Quaker Car Wash, Inc.
    ---------------------------------------------------

Dear Patrick:

In accordance with earlier discussions with you, I have prepared this letter
agreement to further amend the CAR WASH ASSET PURCHASE/SALE AGREEMENT
("Agreement") so that the purchase will be stock for stock rather than stock for
assets. The effective or "as of" closing date is midnight May 8, 1999, stock
issue date is anticipated, but not required, to be May 18, 1999.  The stock will
be placed in escrow, pending the actual closing date of June 30, 1999, or
sooner.

Having noticed 2 typos in the letter amendment of April 7, 1999, I have restated
the 1/st/ and 2/nd/ provisions from that letter.  Please note that in stock for
stock transaction, the inventory is included in the purchase price because it is
one of the assets of the corporation whose stock AWS will acquire. Assumption of
debt is also automatic because of the purchase of the stock, so the purchase
price has been adjusted and a representation as to the amount of debt of the
corporation is included.

1.   Buyer, Millennia Car Wash LLC (herein also referenced as "Original Buyer-
     Assignor"), hereby assigns all  its rights, title, and interests in and to
     the Agreement to American Wash Services, Inc. ("AWS"), and or any parent,
     subsidiary or successor corporation to AWS. Original Buyer-Assignor is
     executing this letter amendment for the sole purpose of completing the
     assignment of its interests to AWS.  All other agreements and amendments
     contained herein are for the benefit of AWS, Mace, any successor in
     interest to either of the foregoing, and Seller, as their interests may
     appear.  Original Buyer-Assignor shall not be deemed to have approved such
     transactions or to have any interest in such transactions or in any
     activities or transactions, which occur with respect to the purchase and
     sale of Seller's business, subsequent to March 30, 1999.

2.   AWS (herein also referenced as "Buyer" or "Buyer-Assignee") hereby accepts
     the assignment from Original Buyer-Assignor of its interests in and to the
     Agreement, and assumes and accepts all duties and obligations arising
     thereunder, from and after March 30, 1999.

3.   It is hereby agreed that American Wash Services, Inc. ("AWS" or "Buyer")
     has the right to assign all of its rights, title, and interests in and to
     the Agreement to Mace Security International, Inc. ("Mace"), a Delaware
     corporation and/or any parent, subsidiary or successor corporation to Mace.
     Mace is sometimes further referred to herein as "Issuer."

4.   The sole shareholder of the corporate Seller has reviewed and approved the
     transactions contemplated by this Agreement.  He has decided to amend the
     entire Agreement so that the transaction contemplated by the Agreement will
     be a sale of stock, in lieu of a sale of assets.  To effectuate the intent
     of this letter Amendment, the Shareholder agrees that his signature
     heretofore affixed to any of the documents constituting this transaction
     (including, without limitation, the Agreement, the Exhibits, and all prior
     Amendments) shall be deemed to be a signature of such shareholder in the
     capacity shown, as well as in his shareholding capacity.

               thereof has been issued (unless the Issuer's Stock shall have

               Seller is an accredited investor as that term is defined in
               Regulation D under the Act.

               (b) Seller represents and warrants that the Issuer's Stock is
               being acquired for its own account without a view to public
               distribution or resale and that Seller has no contract,
               undertaking, agreement or arrangement to sell or otherwise
               transfer or dispose of the Issuer's Stock, or any portion

               (c) Seller represents and warrants that in determining to acquire
               the Issuer's Stock, it has relied solely upon its independent
               investigation, including the advice of its legal counsel and
               accountants or other financial advisors or purchaser
               representatives, and has, during the course of discussions
               concerning its acquisition of the Issuer's Stock, been offered
               the opportunity to ask such questions and inspect such documents
               concerning Buyer and its business and affairs as Seller has
               requested so as to more fully understand the nature of the
               investment and to verify the accuracy of the information
               supplied.

               (d) SELLER ACKNOWLEDGES THAT THE ACQUISITION OF THE CONSIDERATION
               STOCK INVOLVES A HIGH DEGREE OF RISK, and represents and warrants
               that he can bear the economic risk of Seller's acquisition of the
               Issuer's Stock, including the total loss of the investment.

               (e) Seller represents and warrants that (i) he has adequate means
               of providing for his current needs and financial contingencies,
               (ii) he has no need for liquidity in this investment, (iii) he
               has no debts or other obligations, and cannot foresee any other
               circumstances that are likely in the future to require him to
               dispose of the Issuer's Stock, and (iv) all his investments in
               and commitments to non-liquid investments are, and after
               acquisition of the Issuer's Stock will be, reasonable in relation
               to his net worth and current needs.

               (f) Seller understands that no federal or state agency has
               approved or disapproved the Issuer's Stock or made any finding or
               determination as to the fairness of the Issuer's Stock for
               investment.

               (g) Seller understands that the Issuer's Stock is being offered
               and sold in reliance on specific exemptions from the registration
               requirements of federal and state securities laws and the Buyer
               is relying upon the truth and accuracy of the representations,
               warranties, agreements, acknowledgments and understandings set
               forth herein in order to determine the applicability of such
               exemption and the suitability of Seller to acquire the Issuer's
               Stock.

               (h) Seller represents and warrants that he is familiar with the
               business and financial affairs of the Seller corporation and has
               had access to all financial statements prepared by the Seller
               corporation."

     collected, and have been paid over to the proper governmental authorities
     or are held by the corporation in separate bank accounts for such payment
     and all such withholders and collections and other payments due in
     connection therewith are duly set forth on the books of the corporation.

     H. The corporation is not a party to any labor agreement with respect to
     any of its employees with any labor organization, group or association.
     The corporation has not experienced any attempt by organized labor or its
     representatives to make the corporation engage in collective bargaining.
     The corporation is in compliance with all applicable laws respecting
     employment practices, terms and conditions of employment, hiring, and wages
     and hours, including, without limitation, laws relating to civil rights,
     safety and health, workers' compensation, the collection and payment of
     withholding and/or social security taxes, and immigration.  The corporation
     is not engaged in any unfair labor practice.  There is no unfair labor
     practices, charge or complaint against the corporation pending before the
     National Labor Relations Board or any other governmental agency arising out
     of the corporation's activities, and the corporation has no knowledge of
     any facts or information which would give rise thereto; there is no labor
     strike or labor disturbance pending or, to the knowledge of the
     corporation, threatened against the corporation nor is any grievance
     currently being asserted; and the corporation has not experienced a work
     stoppage or other similar labor difficulty.

     I. All material insurance policies (the "Insurance Policies") with respect
     to the property, assets, or business of the corporation are in full force
     and effect and all premiums due and payable thereon have been paid in full.
     Seller will provide a complete list of all Insurance Policies and a summary
     of the coverage and policy limits and deductibles applicable to such

     Insurance Policies. As of the date hereof, there are no pending material
     claims under any Insurance Policy as to which the respective insurers have
     denied coverage.  As of the date hereof, the corporation has not received
     either a written notice or, to the knowledge of the Seller, verbal notice
     that could reasonably be expected to be followed by a written notice of
     cancellation or non-renewal of any Insurance Policy.  The Insurance
     Policies are sufficient for compliance with all requirements of law and of
     all contracts to which the respective corporation is a party and are of a
     type and dollar amount as is customary in the car wash/service station
     industry.  The corporation is not in default under any Insurance Policy and
     the corporation has not failed to give any notice or to present any claim
     under any such Insurance Policy in a due and timely manner where the effect
     of such default or failure would be to render a material claim uninsured.
     The corporation has no knowledge of any notice from any insurer advising of
     reduced coverage or increased premiums on existing Insurance Policies.
     There are no outstanding unpaid claims under any such Insurance Policies.
     Such Insurance Policies are in full force and effect on the date hereof and
     shall be kept in full force and effect by the corporation through the
     Closing Date

     J. The shareholder is transferring good, valid and marketable title to the
     stock free and clear of all encumbrances. Marketable title means that the
     shares are capable of being marketed and not necessarily that there is a
     market for such shares.

16.  Other than as set forth herein, there are no other changes to the terms and
     conditions of the Agreement or the Escrow.

Re: Millennia/AWS/Mace Purchase - Quaker Car Wash, Inc.
    ---------------------------------------------------

Dear Patrick:

This letter agreement is to replace, in toto, the letter I sent you dated June
22, 1999 and the letter dated June 9, 1999.  This letter is to further amend the
CAR WASH ASSET PURCHASE/SALE AGREEMENT ("Agreement") to correct some of the
provisions set forth in the earlier May 10, 1999 letter to you.  The changes
hereby agreed to are as follows:

1.   Item 8 of the May 10/th/ letter amending BPI Item 10:  Subparagraph (b) of
     the third full paragraph contains a parenthetical phrase: "(unless the
     Issuer's Stock shall have been registered under the Act for sale prior
     thereto)".  The foregoing parenthetical phrase is hereby deleted.

2.   Seller agrees that each person who is to receive Mace stock shall execute
     an irrevocable twelve month proxy to Louis D. Paolino, Jr. in the form
     attached hereto and designated "IRREVOCABLE PROXY."  The proper execution
     of such Proxies are a condition to the Close of this Escrow.

3.   Other than as set forth herein, there are no other changes to the terms and
     conditions of the Agreement or the Escrow.

I believe this now reflects your understanding with Steve Prior.  If you have
any questions please do not hesitate to contact me.  Please sign below to
indicate your acceptance of this amendment.  Please FedEx five (5) copies with
your original signature to the Millennia home office, attention Carrie Tonini
and fax one copy to me at (949) 498-7772 and one to Millennia at (760) 635-0578.
Carrie or I  will obtain the additional signatures required and will forward one
fully signed copy to you and one to Escrow.

Re: Millennia/AWS/Mace Purchase - Quaker Car Wash, Inc.
    ---------------------------------------------------

Dear Patrick:

This letter agreement between Buyer and Seller is to restructure the above
transaction.  As you know, the transaction was originally an asset purchase for
cash, then became an asset purchase for stock, and ultimately a stock purchase
for stock.  Now, the parties have agreed to return this transaction to its
status as an asset purchase for stock.  To accomplish their goals, the parties
have also agreed to: increase the purchase price by $55,000.00, to be paid in
cash; provide that inventory will not be included in the sales price or be
handled through escrow, but will be addressed by the parties outside of escrow;
and designate the purchasing entity.  This letter amends the letters of
11/23/98, 1/6/99, 2/26/99, 4/7/99, 5/10/99, and 6/25/99, but only to the extent
set forth below.

As you requested, rather than setting forth each provision amended, this letter
will state the net changes effected by it.

This letter is to amend the CAR WASH ASSET PURCHASE/SALE AGREEMENT ("Agreement")
in accordance with the foregoing. The changes hereby agreed to are as follows:

1.   The Purchase Price is hereby amended to be $2,905,000.00.  The Purchase
     Price shall be paid in the following manner:

               (i) Cash $55,000.00, of which $10,000.00 is in Escrow and shall
               be credited to Buyer's account.


<PAGE>

Patrick Simek, Esq.
Letter Amendment
August 13, 1999
Page 2 of 4



               (ii)Assumption of Debt of not less than One Million Dollars
               ($1,000,000.00) nor more than One Million Five Hundred and Fifty-
               Five Thousand Dollars ($1,555,000.00) per Exhibit "K."
                                                         ----------

               (ii) Balance of the Purchase Price shall consist of between One
               Million Eight Hundred and Fifty Thousand Dollars ($1,850,000.00)
               and One Million Two Hundred and Ninety-Five Thousand Dollars
               ($1,295,000.00) in Mace Securities International, Inc. ("Issuer")
               Stock which, for the purpose of this Agreement only, shall be
               valued at Seven Dollars and Eighty-One Cents ($7.81) per share.
               The exact amount of the balance required to be issued pursuant to
               this subparagraph (ii) shall depend upon the exact amount of the
               Assumption of Debt as specified in subparagraph (ii) immediately
               above. Of the total amount of the Purchase Price, $100,000 in
               shares shall be held back in accordance with BPI Item 11 as
               amended. The remaining shares shall be issued at Close of Escrow.
               At the end of the Hold-Back Period, so much of the Hold-Back
               shares as are then remaining, shall be issued to Seller.

2.   The allocation of the Purchase Price is:

          Land:                       $2,455,000.00
                                      -------------
          Building:                   $  395,000.00
                                      -------------
          Car Wash Equipment:         $   50,000.00
                                      -------------
          Covenant Not to Compete     $    5,000.00
                                      -------------
3.   It is the intent of the parties that the transaction be structured as a
     non-taxable re-organization of stock for assets and not as an exchange of
     stock for stock.  Therefore, all references to acquisition of stock for
     stock are hereby deleted.

4.   Seller is hereby identified as Quaker Car Wash, Inc.

5.   American Wash Services, Inc., which as a result of merger and by operation
     of law has become Mace Wash, Inc., hereby assigns all of its right, title
     and interest in and to the Agreement as amended, to Mace Car Wash, Inc.
     Each of the foregoing is a Delaware corporation and each is a wholly owned
     subsidiary of Mace Security International, Inc.

6.   Inventory is not included in the Purchase Price and Escrow shall not make
     any adjustment for Inventory.  Inventory reimbursement shall be handled
     outside of Escrow, directly between Buyer and Seller.

7.   Date for Close of Escrow is hereby extended to "on or before August 18,
     1999."

8.   Other than as set forth herein, there are no other changes to the terms and
     conditions of the Agreement or the Escrow.

Re:  Mace Car Wash, Inc./Quaker Car Wash, Inc.
     -----------------------------------------

Dear Patrick:

This letter agreement is to further amend the CAR WASH ASSET PURCHASE/SALE
AGREEMENT ("Agreement") dated August 26, 1998, a letter amendment thereto, dated
November 23, 1998, a letter amendment thereto, dated January 6, 1999, a letter
amendment thereto, dated February 26, 1999, a letter amendment thereto, dated
April 7, 1999, a letter amendment thereto, dated May 10, 1999, a letter
amendment thereto, dated June 25, 1999, and a letter amendment thereto, dated
August 13, 1999 ("Amendments").  The changes hereby agreed to are as follows:

1.   The balance of the purchase price payable in common stock of Mace Security
International, Inc. ("Consideration Stock"), shall be issued and delivered to
Seller as of January 3, 2000, except for those shares subject to holdback.

2.   Notwithstanding anything to the contrary set forth in the Agreement or the
Amendments, Seller understands and agrees that the following restrictions and
limitations are applicable to the Seller's purchase and resale  or other
transfer of the Consideration Stock, pursuant to the Securities Act of 1933 (the
"Act") or otherwise:

     (a)  Seller agrees that the Consideration Stock shall not be sold or
otherwise transferred, unless the Consideration Stock is registered under the
Act and state securities laws or is exempt therefrom.

     (b)  A legend in substantially the following form will be placed on the
certificates evidencing the Consideration Stock to be issued to the Seller:

     "The securities represented by this certificate have not
     been registered under the Securities Act of 1933 or any
     state securities act. These shares have been acquired for
     investment and may not be sold, transferred, pledged or
     hypothecated unless (i) they shall have been registered
     under the Securities Act of 1933 and any applicable states
     securities act or (ii) Mace Security International, Inc.,
     shall have been furnished
<PAGE>

     with an opinion of counsel, reasonably satisfactory to
     counsel for Mace Security International, Inc., that
     registration is not required under any such acts."

     (c) For a period of one year after May 8, 1999, Seller shall not sell,
distribute or transfer any of the Consideration Stock without the prior written
consent of the Issuer.

     (d) Upon removal of all other trading restrictions as set forth herein,
Seller agrees that no more than one-sixth (1/6th) of the Consideration Stock
received by Seller after Closing shall be  sold, distributed or transferred in
any 31-day period, nor shall any more than 4,000 shares of stock be traded in
any one day.

     (e) Stop transfer instructions will be imposed with respect to the
Consideration Stock issued to Seller pursuant to this Agreement so as to
restrict resale or other transfer thereof except in accordance with the
foregoing provisions of this Agreement.

3.   The following covenants, representations and warranties shall apply to
Purchaser's delivery and Seller's receipt of the Consideration Stock:

     (a) The Consideration Stock delivered after Closing on January 3, 2000,
will either be registered under the Act for sale to the public in brokers
transactions at the time of delivery to Seller or shall be registered on the
first registration statement filed by Issuer thereafter to register shares
issued in connection with any other acquisition by Issuer or its subsidiaries,
pursuant to a "shelf  registration" on Form S-4 or an other appropriate form, if
Form S-4 is not available under Rule 415 of the Act.  At Purchaser's request,
the Seller shall provide Purchaser with any information required for the
completion of the registration statement.  Notwithstanding the above,
Purchaser's obligation to file the shelf registration and/or keep the shelf
registration continuously effective shall be suspended during any period that
there exists material, non-public information relating to Purchaser.  Purchaser
shall keep such registration statement current and effective, until such time as
the shares may be sold by the Seller at any time pursuant to the provisions of
Rule 144 or otherwise without any restrictions, including restrictions relating
to volume, manner of sale, and notice, or until such earlier date as all of the
shares registered pursuant to such registration statement shall have been sold
or otherwise transferred to a third party.  Purchaser shall also prepare and
file with the Securities and Exchange Commission such amendments and supplements
to such registration statement (and the prospectus used in connection therewith)
as may be necessary to update and keep such registration statement  current and
effective for such period and to comply with the provisions of the Act with
respect to the sale of all securities covered by such registration statement.

     (b) With respect to the Consideration Stock, Purchaser will furnish to the
Seller such number of prospectuses, if required, under the Act, including copies
of preliminary prospectuses, prepared in conformity with the requirements of the
Act, and such other documents as the Seller may reasonably request in order to
facilitate the public sale or other disposition of the securities to be sold by
the Seller.

     (c) Purchaser shall indemnify Seller in accordance with the provisions of
Article IX from and against any and all losses, claims, damages and liabilities
(collectively a "Security Liability") to which
<PAGE>

Seller may become subject under the Act, any state securities or "blue sky" law,
any other statute or at common law, insofar as such Security Liability (or
action in respect thereof) arises out of or is based upon (i) any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereto or any filing or other application under the Act or
applicable federal or state securities law or (ii) any omission or alleged
omission to state therein a material fact required to be stated therein (i.e.,
in any registration statement, prospectus, application or filing), or necessary
in order to make the statements therein not misleading or (iii) any violation or
alleged violation by Purchaser to which Seller may become subject under the Act,
or other Federal or state laws or regulations, at common law or otherwise.
Notwithstanding the above, Purchaser shall not be liable to Seller if and to the
extent that any Security Liability arises out of or is based upon any untrue
statement or omission made in such registration statement, preliminary or final
prospectus or amendment or supplement thereto, in reliance upon and in
conformity with information furnished to Purchaser by Seller which is intended
for such use; and provided further, that Purchaser shall not be required to
indemnify Seller against any Security Liability which arises out of the failure
of Seller to deliver a prospectus.

     (d)  All expenses incurred in effecting the registrations provided for
in this Section shall be paid by Purchaser, including, without limitation, all
registration and filing fees, printing expenses, fees and disbursements of
counsel for Purchaser, underwriting expenses (other than commissions or
discounts which shall be shared by the parties registering shares of Purchaser's
common stock  in proportion to the number of shares registered in each
particular offering), expenses of any audits incident to or required by any such
registration and expenses of complying with the securities or "blue sky" laws of
any jurisdictions.

4.   Other than as set forth herein, there are no other changes to the terms and
conditions of the Agreement or the Amendments.

Please indicate your acceptance of the terms of this Letter amendment by signing

       MACE SECURITY INTERNATIONAL SIGNS DEFINITIVE PURCHASE AGREEMENTS
             TO ACQUIRE TWO WASH LOCATIONS IN TEXAS AND NEW JERSEY

Mount Laurel, New Jersey, September 9, 1999 -- Mace Security International, Inc.
(MSI) (Nasdaq: MACE) today announced the completion of the previously announced
acquisitions of Eager Beaver Car Wash and Hanna Car Wash, operators of five car
washes in Florida and one car wash in Texas, respectively. On a combined basis,
these washes add approximately $5,000,000 in annualized revenue to MSI's
existing operation. The Company now owns and operates 58 car washes throughout
the United States and has a present annualized run rate of approximately $57
million.

Eager Beaver Car Wash operates five full service car washes on the West Coast of
Florida. The car washes provide washing and waxing, and contain professional
detail centers and self-service bays. Eager Beaver represents MSI's first car
wash chain in the southeast region of the United States.

Hanna Car Wash is a "tuck-in" acquisition which strengthens the Company's market
presence in Lubbock, Texas.  Hanna is a full service car wash that provides
washing, waxing, gasoline and detailing.  MSI is the largest operator of car
washes in Lubbock.

"The consummation of these transactions are very important to MSI because of
their geographical location. Eager Beaver is the foundation of our strategy to
aggressively penetrate into the southeast region," said Louis D. Paolino, Jr.,
CEO and Chairman of MSI. "Eager Beaver's previous owner, Ken Bachman, who has
over 20 years experience, is well known and well respected in the car wash
industry. He will join MSI and become a key member of our acquisition team."

Mace Security International, Inc. is a provider of car care services which owns
and operates numerous car washes nationwide. The Company is also a leading
producer of less lethal defense sprays for the consumer market and a marketer of
consumer safety and security products.
