Enviro-Clean's files and records to Enviro-Clean and other authorized parties.

Enviro-Clean's files, records and data retained by B2B, but Enviro-Clean
recognizes that events beyond the control of B2B may cause such loss or
alteration. B2B will maintain backup file(s) containing all the data, files and
records related to Enviro-Clean. Enviro-Clean's file(s), records and data shall,

Enviro-Clean to ensure that the information it transmits and receives complies
with all applicable laws and regulations.

officers, directors and employees ("B2B Indemnitees") from and against, and
shall reimburse them for, any losses, claims, damages and liabilities (including
costs and expenses attendant thereto, including reasonable attorneys' fees)
which may be sustained, suffered or incurred by the B2B Indemnitees, arising
from or in connection with (i) the breach of any of Enviro-Clean's
representations, warranties or covenants contained in this Agreement, (ii) any
content presented on the EC Site, except to the extent such content was provided
by B2B or (iii) the operation of the EC Site, including without limitation,
improper use of software and infringement of patents or other intellectual
property.

                  (b) B2B shall indemnify and hold harmless Enviro-Clean and its
officer, directors and employees (the " EC Indemnitees") from and against, and
shall reimburse them for, any losses, claims, damages and liabilities (including
costs and expenses attendant thereto, including reasonable attorneys' fees)
which may be sustained, suffered or incurred by the EC Indemnitees, arising from
or in connection with (i) the breach of any of B2B's representations, warranties
or covenants contained in this Agreement, and (ii) any content presented on the
B2B Site, except to the extent such content was provided by Enviro-Clean or its
vendors.

                  (c) A party required to make an indemnification payment
pursuant to this Section ("Indemnifying Party") shall have no liability to make
such payment unless the party or parties entitled to receive such
indemnification payment (each an "Indemnified Party") gives notice to the
Indemnifying Party specifying (i) the covenant, representation or warranty
contained herein which it asserts has been breached, (ii) in reasonable detail,
the nature and dollar amount of any claim the Indemnified Party may have against
the Indemnifying Party by reason thereof under this Agreement, and (iii) whether
the claim is a third-party claim or a direct claim of the Indemnified Party
against the Indemnifying Party.

                  (d) If an Indemnified Party becomes aware of a third-party
claim for which an Indemnifying Party would be liable to an Indemnified Party
hereunder, the Indemnified Party shall, with reasonable promptness, notify in
writing the Indemnifying Party of such claim,

<PAGE>

identifying the basis for such claim and the amount or the estimated amount
thereof to the extent then determinable which estimate shall not be conclusive
of the final amount of such claim (the "Claim Notice"); provided, however, that
any failure to give such Claim Notice will not be deemed a waiver of any rights
of the Indemnified Party except to the extent the rights of the Indemnifying
Party are actually prejudiced by such failure. The Indemnifying Party, upon
request of the Indemnified Party, shall retain counsel (who shall be reasonably
acceptable to the Indemnified Party) to represent the Indemnified Party and
shall pay the reasonable fees and expenses of such counsel with regard thereto;
provided further, however, that any Indemnified Party is hereby authorized,
prior to the date on which it receives written notice from the Indemnifying
Party designating such counsel, to retain counsel, whose reasonable fees and
expenses shall be at the expense of the Indemnifying Party, to file any motion,
answer or other pleading and take such other action which it reasonably shall
deem necessary to protect its interests or those of the Indemnifying Party until
the date on which the Indemnified Party receives such notice from the
Indemnifying Party. After the Indemnifying Party shall retain such counsel, the
Indemnified Party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually
agreed to the retention of such counsel or (ii) the named parties of any such
proceeding (including any impleaded parties) included both the Indemnifying
Party and the Indemnified Party and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. If requested by the Indemnifying Party, the Indemnified Party
agrees to cooperate with the Indemnifying Party and its counsel in contesting
any claim or demand which the Indemnifying Party defends. A claim or demand may
not be settled by any party without the prior written consent of the other party
(which consent will not be unreasonably withheld) unless, as part of such
settlement, the Indemnified Party shall receive a full and unconditional release
reasonably satisfactory to the Indemnifying Party. Notwithstanding the
foregoing, the Indemnifying Party shall not settle any claim without the prior
written consent of the Indemnified Party if such claim is not exclusively for
monetary damages.

         9.       Late Payments and Resolution of Payment Disputes.

of this Agreement. Each party shall be entitled to offset amounts owed to it by
the other party under the terms of this Agreement against amounts it owes to
such other party.

this Agreement that the parties have been unable to resolve by the normal and
routine channels ordinarily used for such matters. In order to resolve a
dispute, the parties shall first follow the informal and escalating procedures
set forth below.

                           (i) The complaining party's representative will
         notify the other party's representative in writing of the dispute, and
         the non-complaining party will exercise good faith efforts to resolve
         the matter as expeditiously as possible.

                          (ii) In the event that such matter remains unresolved
         thirty (30) days after the delivery of the complainant party's written
         notice , a senior representative of

<PAGE>

         each party shall meet or confer within ten (10) business days of a
         request for such a meeting or conference by either party to resolve
         such matter.

                         (iii) In the event that the meeting or conference
         specified in (ii) above does not resolve such matter, the senior
         officer of each party shall meet or confer within ten (10) business
         days of a request for such a meeting or conference by either party to
         resolve such matter.

                          (iv) If the parties are unable to reach a resolution
         of the dispute after following the above procedure, or if either party
         fails to participate when requested, the parties may proceed in
         accordance with paragraphs (c)-(e) below.

                  (c) Any dispute shall, after utilizing the procedures in this
section , be resolved by final and binding arbitration in New York, New York,
before a single arbitrator selected by, and in accordance with, the rules of
commercial arbitration of the American Arbitration Association. Each party shall
bear its own costs in the arbitration, including reasonable attorneys' fees, and
each party shall bear one-half of the cost of the arbitrator.

                  (d) The arbitrator shall have the authority to award such
damages as are not prohibited by this Agreement and may, in addition and in a
proper case, declare rights and order specific performance, but only in
accordance with the terms of this Agreement.

                  (e) Any party may apply to a court of general jurisdiction to
enforce an arbitrator's award, and if enforcement is ordered, the party against
which the order is issued shall pay the costs and expenses of the other party in
obtaining such order, including reasonable attorneys' fees.

         10.      Early Termination.

                  (a)  At any time when Enviro-Clean owns less than 10% of the
outstanding voting stock of B2B, based on the aggregate number of votes carried
by shares of common and preferred stock of B2B outstanding, each party shall
have the right to terminate this Agreement by giving 30 days written notice of
its election to terminate to the other party.

                  (b)  Enviro-Clean may terminate this Agreement upon ten days
prior written notice if it experiences Repeated Unavailability of the Vendor
Management Services. "Repeated Unavailability" shall mean the unavailability of
the Vendor Management Services to process orders placed through the EC Site for
a sustained period of four or more hours on three or more occasions during any
one calendar month, excluding unavailability as a result of regularly scheduled
system maintenance, failures wholly related to error or omission by
Enviro-Clean, web hosts, system integrators or communications service providers
other than B2B or entities hired or contracted by B2B or Enviro-Clean in
connection with the Vendor Management Services, and regional or national
Internet or communications outages outside the control of B2B. In no event will
B2B be liable to any third party for any claims arising out of or related to
Repeated Unavailability for any lost revenue, lost profits, replacement goods,
loss of technology, rights or services, incidental, punitive, indirect or
consequential damages, loss of data, or interruption or loss of use of service
or Enviro-Clean's business, even if advised of the possibility of such

                  (a)  Neither party shall assign or otherwise transfer this
Agreement in whole or in part, or any of the rights and obligations hereunder,
either voluntarily or by operation of law, without the other's written consent.

                  (b)  Neither party shall be deemed to be in default or have
breached any provision of this Agreement solely as a result of any delay,

indirectly from any act of God, civil or military authority, civil disturbance,
war, laws, regulations, acts or orders of any government or agency or official
thereof, or any other occurrences beyond the party's reasonable control.

                  (c)  No waiver of any provision of this Agreement or of any
rights or obligations of either party hereunder shall be effective unless in
writing and signed by the party or parties waiving compliance, and any such
waiver shall be effective only in the specific instance and for the specific
purpose stated in such writing.

                  (d)  The execution and delivery of this Agreement shall not be
deemed to confer any rights or remedies upon, nor obligate any of the parties
hereto, to any person or entity other than such parties. Nothing in this
Agreement shall cause or be deemed to cause the parties to be partners or joint
venturers with, or agent or employees of, each other. The parties are
independent contractors, and neither party shall have any right or power to
create any obligation or responsibility on behalf of the other party.

                  (e)  B2B shall not be liable to Enviro-Clean or to any third

difficulties, storms, strikes, walk-outs, equipment or systems failures, or
other causes over which B2B, its affiliates, employees, officers, or agents have
no reasonable control, or for loss or damage, direct or indirect, resulting from
inaccuracies, erroneous statements, errors of facts, omissions or errors in the
transmission or delivery of Vendor Management Services, or any data provided as
a part of the Vendor Management Services pursuant to this Agreement, except to
the extent caused by the gross negligence or wilful misconduct of B2B.

                               PROMISSORY NOTE

                                                        Dated: November 15, 1999

The Promissory Note dated July 1, 1999 is hereby amended and restated to read as
follows:

     FOR VALUE RECEIVED, b2bstores.com Inc., a Delaware corporation (the
"Maker"), hereby promises to pay to the order of Enviro-Clean of America, Inc.
(the "Payee"), at 211 Park Avenue, Hicksville, New York 11801, or such other
place as may from time to time be designated by notice thereof from the Payee
hereof to the Maker, the principal sum as shall have been advanced from time to
time from Payee to Maker (as set forth on the schedule to this Note ("Grid")),
together with interest on the unpaid principal sum outstanding at a rate equal
to eight percent per annum. Principal and interest shall be due and payable on
the earlier of (i) February 1, 2000 and (ii) the date the Maker consummates an
offering of its equity securities yielding gross proceeds of at least
$2,000,000.

     Interest shall be payable on any installment of principal and interest not
paid to the Payee on its due date as set forth above at a per annum rate equal
to the lesser of (i) 18%, or (ii) the highest rate permitted by law, from the
date such installment was due and payable to the Payee until the date such
installment is fully paid.

     If any of the following events shall occur:

     (i) the Maker shall default in the payment of principal of, or interest on,
this Note or any indebtedness for borrowed money in excess of $50,000, or shall
default in the performance or observance of the terms of any instrument pursuant
to which such indebtedness was created or is secured, the effect of which
default is to cause or permit any holder of any such indebtedness to cause the
same to become due prior to its stated maturity;

     (ii) any judgment against the Maker or any attachment, levy or execution
against any of its properties for any amount shall remain unpaid, or shall not
be released, discharged, dismissed, stayed or fully bonded for a period of 10
days or more after its entry, issue or levy, as the case may be; or

     (iii) the Maker shall make an assignment for the benefit of creditors, or a
trustee, receiver or liquidator shall be appointed for the Maker or for any of
its property, or the commencement of any proceedings by the Maker under any
bankruptcy, reorganization, arrangement of debt, insolvency, readjustment of
debt, receivership, liquidation or dissolution law or statute, or the
commencement of any such proceedings without the consent of the Maker and such
proceedings shall continue undischarged for a period of 10 days;
<PAGE>

then, in any such event, the Payee may declare the entire unpaid principal
amount of this Note, and all interest accrued and unpaid hereon, to be forthwith
due and payable, whereupon the same shall become and be forthwith due and
payable, without presentment, demand, protest or notice of any kind, all of
which are hereby expressly waived by the Maker.

     No failure on the part of the Payee to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise by Payee of any right hereunder preclude any other or
further exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

     In the event this Note is turned over to an attorney for collection or
Payee otherwise seeks advice of an attorney in connection with exercise or
enforcement of its rights hereunder, the Maker agrees to pay all costs of
collection, including reasonable attorneys' fees and expenses, which amounts
may, at the Payee's option, be added to the principal hereof.

     No amendment, modification or waiver of any provision of this Note, nor
consent to any departure by the Payee therefrom, shall be effective unless the
same shall be in writing and signed by the Payee, and then such waiver or
consent shell be effective only in the specific instance and for the specific
purpose for which it is given.

     This Note has been executed and delivered in the State of New York and the
construction, validity and performance hereof shall be governed by the internal
laws of the State of New York without regard to the principles of conflict of
laws. Any action, suit or proceeding in respect of or arising out of this Note
may be brought by Payee in federal or state court located in Nassau County. In
any such action, suit or proceeding, Maker waives trial by jury, and Maker also
waives (i) the right to interpose any setoff or counterclaim of any nature or
description; (ii) any objection based on forum non-conveniens or venue; and
(iii) any claim for consequential, punitive, or special damages.

     This Note shall be binding upon the Maker and its successors and assigns,
and the terms hereof shall inure to the benefit of the Payee and its successors
and assigns, including subsequent holders hereof.

     All notices hereunder from the Payee to the Maker shall be in writing and
mailed to the Maker at the above address by registered or certified mail, return
receipt requested. All such notice shall be deemed given when mailed.

                                      2

     Maker hereby authorizes Payee to complete and revise the Grid and to
reflect thereon the making of any loan made to Maker hereunder. Payee shall send
a copy of the Grid to Maker promptly after any revision thereto. The Grid, as
completed and/or revised by Payee, shall be final and binding on Maker in the
absence of fraud or mathematical error.

     IN WITNESS WHEREOF, the undersigned has duly executed this instrument on
the date set forth above.
