     equip2move.com Corporation, a Delaware corporation (the "Company"), the
principal office of which is located c/o Koster Industries Inc., 555 Broadhollow
Road, Melville, New York 11747, hereby promises to pay to Enviro-Clean of
America, Inc., a Nevada corporation, or its assigns (the "Payee"), the principal
amount of ONE MILLION DOLLARS ($1,000,000) (the "Principal"), plus interest
(calculated on the basis of a year of 365 days and actual days elapsed) on the
unpaid Principal of this Convertible Promissory Note (the "Note") until such
Principal has been paid in full, at the Prime Rate. "Prime Rate" means the rate
of interest publicly announced by Bank of America (or its successor) as its
prime lending rate. Amount(s) of the Principal shall be deemed outstanding as of
the date of this Note, and the outstanding balance hereof shall be due and
payable either: (i) in full by November 1, 2000 (the "First Maturity Date"), if
the Company has raised an aggregate of at least $1,000,000 in capital (the "July
to November Financing"); provided that all capital received by the Company from
the July to November Financing is immediately due and payable to Payee as the
Company receives such capital, or (ii) if the aggregate total of the July to
November Financing is less than $1,000,000, then the total amount due by the
First Maturity Date shall equal the aggregate amount of the July to November
Financing which shall be paid to the Payee as it is received by the Company and
the remaining balance under this Note shall be due and payable on February 1,
2001 (the "Final Maturity Date"), as described in Section 1 below. A check or
checks for all payments hereunder shall be delivered to the Payee at the address
for such payments designated in writing by the Payee to the Company. The Company
may prepay all or any part of the principal amount of this Note, together with
accrued interest on the Principal amount so prepaid, at any time without premium
or penalty. This Note shall be senior in repayment to all other obligations of
the Company.

          This Note has been issued pursuant to the terms of the Stockholders'
Agreement, dated as of May 31, 2000, by and between Koster Industries Inc.,
Enviro-Clean of America, Inc., Corporate Assets International Inc., Prestige
Equipment Corporation, Rosen Systems, Inc., Rodney Schultz, Jerry Root,
equip2move.com Corporation and b2bstores.com, Inc. as amended
<PAGE>

by Amendment No. 1 to the Stockholders' Agreement dated __________ (together,
the "Stockholders' Agreement") to which reference is made for all purposes.
Terms used herein with initial capital letters and not defined herein, if any,
have the meanings given them in the Stockholders' Agreement and/or the
Amendment.

     This Note is subject to the following additional provisions:

          1.   Final Payment or Conversion of the Note.

               (a)    Final Payment of the Note on the Final Maturity Date. In
conjunction with the provisions of the Stockholders' Agreement and provided that
the following have occurred: (i) the balance of this Note is not paid in full by
the First Maturity Date; and (ii) the Company has raised an aggregate amount of
$2,250,000, excluding the proceeds from this Note, through Payee or third party
financing sources ("Third Party Financing") by February 1, 2001, then the
remaining balance under this Note, including all accrued and unpaid interest,
shall be paid in full to the Payee on the Final Maturity Date.

               (b)    Conversion of the Note into Capital Stock at the Final
Maturity Date. In conjunction with the provisions of the Stockholders' Agreement
and provided that the following have occurred: (i) the balance of this Note is
not paid in full by the First Maturity Date; and (ii) the Company has not raised
an aggregate amount of $2,250,000, excluding the proceeds from this Note,
through Third Party Financing by February 1, 2001, then the Payee will be
obligated to invest an additional $2,250,000 less the total amount of: (i) the
Third Party Financing actually raised by the Company up to the Final Maturity
Date, and (ii) the remaining balance under this Note. The total amount of the
$2,250,000 investment will be made in exchange for 15% of the outstanding
capital stock of the Company (the "Capital Stock"), at which time this Note
shall be cancelled; provided, however, that if the Payee, for any reason, fails
to comply with the provisions of this Section 1(b), the balance of the Note
shall be immediately convertible into Capital Stock. The amount of Capital Stock
which the balance of the Note shall convert into shall equal the following: 15%
of the Capital Stock multiplied by a fraction, the numerator of which is equal
to the outstanding balance of the Note and the denominator of which is
$2,250,000.

               (c)    Issuance of Securities Upon Conversion of this Note. Upon
the conditions as set forth in Section 1(b) above, the Payee shall surrender
this Note and cause the Third Party Financing to be delivered at the office of
the Company for the applicable number of shares of Capital Stock. Thereupon,
there shall be issued and delivered to Payee a certificate or certificates of
shares representing the Capital Stock into which the unpaid Principal balance
and accrued interest of this Note has been converted, along with the Capital
Stock purchased in connection with the Third Party Financing by the relevant
parties.

               (d)    Cash in Lieu of Fractional Shares. No fractional share or
interest of shares of Capital Stock or scrip representing any such fractional
share or interest, shall be issued upon conversion of this Note. Instead of any
such fractional shares or interests which would otherwise be issuable upon
conversion of this Note, the Company shall pay to the Payee a cash adjustment in
respect of such fraction in an amount equal to the fraction of the share
<PAGE>

multiplied by the purchase price per share of Capital Stock as set calculated at
the time of conversion.

               (e)    Cancellation of Note. This Note shall be cancelled upon
the conversion of the entire outstanding principal amount of this Note and all
accrued and unpaid interest thereon, in accordance with the terms hereof, or
upon the payment of all Principal amounts of this Note and all accrued interest
thereon.

     2.   Securities Laws.  The Payee, by acceptance hereof, represents that it
is an "accredited investor" as such term is defined in Rule 501 of the
Securities Act and agrees that this Note is being acquired for investment for
its own account and that the Payee will not offer, sell or otherwise dispose of
this Note or the shares of the securities issuable upon conversion thereof
except under circumstances which will not result in a violation of the
Securities Act of any applicable state securities law or similar laws relating
to the sale of securities.  Payee agrees to execute and deliver the Company's
Investor Letter to the Company which is attached hereto as Exhibit A.
                                                           ---------

its rights or obligations hereunder without the prior written consent of Payee.
The Payee may at any time enter into assignment agreements or participations
with other lenders or persons with the written consent of the Company. All
stipulations, promises and agreements in this Note shall be binding on the
successors and/or assigns of the Company whether so expressed or not. Any
assignee of Company or Payee shall agree in writing prior to the effectiveness
of such assignment to be bound by the provisions hereof.

     4.   Default Under this Note. The following shall constitute an event of
default ("Events of Default"):

          (a)  the Company shall fail to make the payment of the principal
and/or interest on the First Maturity Date and/or the Final Maturity Date or the

          (b)  the Company shall; (1) admit in writing its inability to pay for

The Company agrees to pay all costs and expenses of collection and enforcement,
including without limitation reasonable attorneys' fees and expenses.

                   AMENDED AND RESTATED SETTLEMENT AGREEMENT
                   -----------------------------------------

     This Amended and Restated Settlement Agreement (this "Agreement") is made
and entered into on this _____ day of July, 2000, by and between THOMAS B.
HAINES ("Haines") and ENVIRO-CLEAN OF AMERICA, INC., a Nevada corporation (the
"Company").

     WHEREAS, Haines and the Company entered into a Settlement Agreement on
March 31, 2000 wherein, among other things, the Company agreed to assist Haines
in the disposition of the Company's common stock, par value $0.001 (the "Common
Stock") held by, or to be held by Haines. A copy of the March 31, 2000
Settlement Agreement is attached hereto and marked Exhibit A and incorporated
herein by reference for all relevant purposes (the "Original Agreement"); and

     WHEREAS, the Company and Haines desire to amend certain provisions of the
Original Agreement by amending and restating the Original Agreement in its
entirety as herein provided and this Amended and Restated Agreement will
supercede the Original Agreement and upon the execution hereof shall represent
the Settlement Agreement by and between the Company and Haines.

     NOW THEREFORE, in consideration of the mutual covenants herein contained
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

     1.   500,000 Shares.  The Company will either purchase, or use its best
          --------------
efforts to assist Haines in the sale of, 500,000 shares of the Common Stock (the
"Shares") beneficially held by Haines at a price of no less than $2.00 per
share, with the purchase of 250,000 shares to be consummated on or before August
1, 2000 and the purchase of the remaining 250,000 shares to be consummated on or
before August 15, 2000.  Haines will prepare and deliver on or before July 19,
2000 the purchase agreement between Haines and the buyer(s) of Shares which
shall contain such representations, warranties, terms and conditions as are
reasonably acceptable to Haines and such buyer(s).  It is the intent of the
parties that the purchase agreement to be delivered to the Company shall be
substantially similar to the purchase agreement used in connection with Haines'
previous sale of 500,000 of his shares in the Company for a total purchase price
of $1,500,000.  If the Company is not the buyer, it is understood and agreed
that the Company will not be acting as a broker or finder in any such sale and
will not be compensated for any of its efforts, but will facilitate any sale and
purchase by expediting stock transfers and providing Haines with an escrow
account. All buyers shall be "accredited investors" as such term is defined
under Regulation D, promulgated under the Securities Act of 1933.  Haines
represents and warrants that in formulating his decision to sell the Shares, he
has had the opportunity to ask questions and receive answers from the Company
concerning the Company and its business and prospects, and he has been permitted
to have access to all information which he has requested in order to evaluate
the merits and risks of the sale of the Shares.  Haines has been represented by
independent legal counsel with respect to the sale of the Shares and has
received such financial advice as he deems necessary from financial advisors of
<PAGE>

his own choosing.  In addition, Haines understands that in the future the
Company may issue its stock in a public or private offering for a price higher
than the price Haines receives for the Shares, or may effect a sale of the
Company or substantially all of its assets.

     2.   Relocation of Florida Office.  Haines understands that, upon
          ----------------------------
consummation of the sale of the Shares and receipt of the entire sales proceeds
by Haines or Haines' attorneys, the Company, at its sole cost and expense, will
commence to close the Florida office of NISSCO/NIPPCO/Sunline, Inc.
(collectively "NISSCO"), a subsidiary of the Company, and relocate as much or
all of the furniture, computers, files and staff thereof to Texas as it deems to
be necessary and advisable.  It is anticipated that this move will take place by
August 31, 2000.  Haines agrees to assist the Company in this relocation process
prior to August 5, 2000 and after August 20, 2000. In furtherance of this move,
Haines shall coordinate with the Company's management, and will deliver new
signature cards from Nissco's bank accounts to Randall K. Davis.

     3.   Resignation; Consulting; Severance Payments.  Haines hereby resigns
          -------------------------------------------
from all positions with the Company and NISSCO effective as of the date Haines
or his attorneys have received the entire sales proceeds from the sale of the
Shares (the "Resignation Date").  From the Resignation Date through December 31,
2000, Haines agrees to provide consulting services to the Company.  Haines will
not be required to travel, but will be required to be reasonably available by
phone. Failure to comply with these requirements will excuse the Company's
obligations to make severance payments as described in this Section 3 of this
Agreement. The termination of the Company's obligation to make severance
payments under this Section 3 shall be the sole and exclusive remedy available
to the Company if Haines fails to comply with the requirements of this Section
3. Commencing on the Resignation Date and ending on December 31, 2000, the
Company will pay Haines severance pay at the rate of $6250 per month which shall
also be the full consideration for Haines's consulting services; provided that
the first months' payment shall be prorated if the Resignation Date is on any
date other than the first day of the month.  The payments shall be made in
consecutive monthly installments on or before the first day of each month;
provided that the first month's payment shall be made on or before the
Resignation Date.  This is not required by any pre-existing policy or agreement.

     4.   Confidentiality; Return of Company Property. Haines will return all of
          -------------------------------------------
the Company's property in his immediate possession no later than 5:00 p.m.
August 15, 2000. Such property shall be returned to the Company's Florida
office. This includes but is not limited to, computer equipment, cellular phone,
pager, keys, credit cards, long distance calling card, and any confidential
and/or proprietary information or files. Failure to return Company property as
required by this Agreement will excuse the Company's obligation to make
severance payments described in Section 3 of this Agreement.

     Haines acknowledges that he has been permitted access to documents and
exposed to other information regarding the confidential affairs of the Company
and NISSCO, which may include, without limitation, information about their past,
present and future financial condition, the markets for their services, key
personnel, trade secrets, current and prospective customer lists, price data,
purchasing information, operational methods, acquisition plans, prospects, plans
for future development and other business affairs and information, all of which
is information not available to the public, or which is protectable under
copyright, trademark, patent, or similar
<PAGE>

law (the "Confidential Information"). Haines covenants and agrees that at no
time shall he ever divulge, disclose or otherwise use any Confidential
Information, unless and until (a) such information is available in the public
domain by reason other than Consultant's unauthorized disclosure or use thereof,
unless such disclosure or use is expressly authorized by the Company's Chief
Executive Officer in writing in advance of such disclosure or use, or (b)
disclosure is required pursuant to a legal proceeding and Haines provides the
Company with reasonable advance notice of such disclosure. Haines also hereby
acknowledges and agrees that all Confidential Information shall remain the sole
property of the Company and that Haines has not and shall not acquire any right,
title or interest in and to any of the Confidential Information.

     5.   Restrictive Covenants Applicable to Haines. For a period of one (1)
          ------------------------------------------
year immediately following the date of execution of this Agreement, Haines shall
not, within the United States of America:

          (a)  participate directly or indirectly as an owner, partner, limited
     partner, joint venturer, member, employee, consultant, officer, director,

     interest in the voting securities of a corporation, the shares of which are
     traded on a national securities exchange or in the over-the-counter market)
     in or otherwise be associated in any manner connected with or render
     services or advice to, whether or not for compensation, any person or
     entity who or which is in the business of forming and maintaining buying

     Business");

          (b)  induce or attempt to induce any person who, at any time during
     the term of Haines' employment at NISSCO, was a customer, supplier,
     licensee, or business relation of NISSCO, the Company or any of the
     Company's other subsidiaries, to cease doing business with Company, or in
     any way interfere with the relationship between any such customer,
     supplier, licensee or business relation and Company;

          (c)  directly or indirectly, either for himself or any other person,
     solicit the business of any person who at any time during Haines'

     Company's other subsidiaries, whether or not Haines or a person under
     Haines' control had personal contact with such person, with respect to
     products or activities which compete in whole or in part with the
     Janitorial Buying Group Business of the Company or any of its subsidiaries;

          (d)  directly or indirectly, on Haines' own behalf or in the service
     of or on behalf of others, solicit, divert, recruit, or employ any employee

     competitor of the Company; and

     Haines agrees that the covenants set forth in this Section 5 are reasonable
with respect to their duration, geographical area and scope.  In consideration
for Haines' agreement to abide by the covenants set forth in this Section 5, the
Company hereby agrees to pay Haines $96,000 (the "Non-Compete Fee"), which shall
be in addition to the other payments to be made by the Company pursuant to the
terms of this Agreement. The Non-Compete Fee shall be paid in consecutive
monthly installments of $8,000 on or before the first day of each month,

relief, (ii) discontinuing payment of the monthly installments of the Non-
Compete Fee which are due after the date of the breach; (iii) discontinuing
payment of the monthly installments of the severance pay as described in Section
3 which are due after the date of the breach and (iv) any and all other legal
and equitable remedies available under applicable law. In the event the Company

Compete Fee when due, then the covenants applicable to Haines under this Section
5 shall immediately terminate and be of no further force or effect and any and
all other legal and equitable remedies will be available to Haines under
applicable law.

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

except to the Company's attorneys, accountants, and employees, and to Haines'
attorneys, personal tax advisor and spouse, or as may be required by legal
process.  The parties agree to use their best efforts to prevent any future
publicity or disclosure of this Agreement and the matters contained herein,
including but not limited to instructing those to whom disclosure is permitted
that its terms are confidential and must not be disclosed, and securing from
those to whom disclosure is allowed their agreement not to divulge said
information, but to maintain its confidentiality.  In the event confidentiality
of this agreement is breached, each of the parties understands and agrees that
he or it will be liable to the other party for any damages arising therefrom.

     9.   Representation of Counsel.  The parties hereto, jointly and
          -------------------------
individually, hereby acknowledge that they have been represented by counsel in
connection with the giving and execution of this Agreement; that they understand
the meaning of this document; that they intend to be legally bound by all of the
terms set forth herein; and that they have received consideration deemed by them
and their counsel to be sufficient for the giving and execution of this
document.

     10.  Limitation on Remedies.  Notwithstanding anything contained in this
          ----------------------
Agreement to the contrary, neither party shall have the right to raise or assert
as a remedy for any breach of this Agreement by the other party the remedy of
rescission with respect to the sale of the Shares as described in Section 1
hereof.

     11.  Miscellaneous.  No amendment, modification, or discharge of this
          -------------
Agreement, and no waiver hereunder, shall be valid or binding unless set forth
in writing and duly executed by the party against whom enforcement of the
amendment, modification, discharge, or waiver is sought.  No delay or failure at
any time on the part of either party in exercising any right, power, or
privilege under this Agreement, or in enforcing any provision of the Agreement,
shall impair any such right, power, or privilege, or be construed as a waiver of
such provision, or be construed as a waiver of any default or as any
acquiescence therein, or shall affect the right of such party thereafter to
enforce each and every provision of this Agreement in accordance with its terms.
This Agreement constitutes the entire agreement between the parties hereto with
respect to the subject matter hereof, and supersedes all prior oral or written
agreements,
<PAGE>

commitments, or understandings with respect to such matters, including the
Original Agreement. This Agreement or any interest herein may not be assigned by
either party in whole or in part without the prior written approval of the other
party. This Agreement shall be binding upon and shall inure to the benefit of
the parties hereto and their respective permitted heirs, successors and assigns.
The section headings contained herein are for the purposes of convenience only
and are not intended to define or limit the contents of said sections. This
Agreement shall be governed by and interpreted in accordance with the laws of
the State of Texas. The provisions of this Agreement are several and the
invalidity or unenforceability of any provision hereof shall not effect the
validity or enforceability of any other provision. In addition, in the event
that the provision of this Agreement (or a portion thereof) is determined by the
Court to be unenforceable as drafted by the virtue of the scope, duration,
extent or character of any obligation contained therein, the parties acknowledge
that it is their intention that such provision (or portion thereof) shall be
construed in a manner designed to effectuate the purposes of such provision to
the maximum extent enforceable under applicable law. If any of the covenants set
forth in Sections 5 or 8 are held to be unreasonable, arbitrary or against
public policy, such covenants will be considered divisible with respect to
scope, time and geographic area, and will be effective, binding and enforceable
against Haines in such lesser scope, time and geographic area as a court of
competent jurisdiction determines to be adequate under the circumstances.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above-written.
