advantage if used to compete with Employer. In order to avoid such unfair
advantage, Executive agrees that while he/she is employed with Employer and for
a period equal to one (1) year after the date of a voluntary termination of
employment (the "Restricted Period"), he shall not, directly or indirectly,
individually or as an owner, lender, consultant, adviser, independent
contractor, employee, partner, officer, director or in any other capacity, alone

way in competition with Employer in any business at the time the termination
occurs, including, but not limited to, computer resellers, service companies
providing the same services as CompuCom, and computer retail companies.
Executive also agrees that, for the Restricted period, he/she will not, either
directly or indirectly, solicit any employee or other independent contractor of

Executive will not compete for the same period of time for which payments are
received in accordance with Subsection 6.3.

education, experience and/or abilities are such that he/she can obtain

this Agreement through temporary and/or permanent injunctive relief will not
prevent him from earning a livelihood and will not cause an undue hardship upon
him. Executive hereby acknowledges that $16,666.67 of his monthly salary
described in Subsection 2.1 is paid by Employer in consideration for Executive's
agreement to be bound by the non-competition provisions of this Agreement.

New York, New York time, on a Business Day, the exercise of the Warrants to
which such item relates will be deemed to be effective on the next succeeding

Warrants on the Expiration Date, if all of the items referred to in the last
sentence of the preceding paragraph are received by the Warrant Agent at or
prior to 5:00 p.m., New York, New York time, on such Expiration Date, the
exercise of the Warrants to which such items relate will be effective on the
Expiration Date.

     Subject to the terms of the Warrant Agreement, as soon as practicable after

issued to or upon the written order of the registered holder of this Warrant
Certificate, a certificate or certificates evidencing the Share or such holder
pursuant to the Election to Exercise, as set forth on the reverse of this
Warrant Certificate.  Such certificate or certificates evidencing the Share or
Shares shall be deemed to have been issued and any persons who are designated to
be named therein shall be deemed to have become the holder of record of such
Share or Shares as of the close of business on the date upon which the exercise
of this Warrant was deemed to be effective as provided in the preceding
paragraph.

     The Company, at its option, may provide the holder of this Warrant written
notice (the "Call Notice") that this Warrant shall terminate on the 20th day
following the date of delivery of the Call Notice (such date being the "Early
Termination Date"), as described in the Warrant

                                       3

Agreement, at any time: (i) the Closing Per Share Market Price of the Common
Stock has been equal to or greater than 200% of the Warrant Exercise Price on
the date of delivery of the Call Notice and the 19 consecutive Trading Days
immediately preceding the date delivery of the Call Notice (the "Call Notice
Period") and (ii) after the Registration Statement has been declared effective
and has been effective for the Call Notice Period. In the event that the Warrant
is not exercised by the holder of this Warrant on or before the Early
Termination Date, this Warrant shall expire at 5:00 p.m., New York, New York
time, on the Early Termination Date, and the Company will remit to the holder of
the Warrant $.10 per Warrant upon such holder tendering to the Company the
expired Warrant Certificate.

     Upon due presentment for registration of transfer of this Warrant
Certificate at any office or agency maintained by the Company for that purpose,
a new Warrant Certificate evidencing in the aggregate a like number of Warrants
shall be issued to the transferee in exchange for this Warrant Certificate,
subject to the limitations provided in the Warrant Agreement, without charge
except for any tax or other governmental charge imposed in connection therewith.

     The Company and the Warrant Agent may deem and treat the registered holder
hereof as the absolute owner of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone) for the purpose of
any exercise hereof and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary.

     The term "Business Day" shall mean any day on which (i) banks in New York,
New York, (ii) the principal national securities exchange or market on which the
Common Stock is listed or admitted to trading and (iii) the principal national
securities exchange or market on which the Warrants are listed or admitted to
trading are open for business.

                      Transferee Letter of Representation

Enviro-Clean of America, Inc.
211 Park Avenue
Hicksville, New York  11801-1408

Ladies and Gentlemen:

     In connection with our proposed purchase of warrants to purchase Common
Stock, par value $.001 per share (the "Securities"), of Enviro-Clean of America,
Inc. (the "Company") we confirm that:

     1.   We understand that the Securities have not been registered under the
Securities Act of 1933, as amended (the "Securities Act") and, unless so
registered, may not be sold except as permitted in the following sentence. We
agree on our own behalf and on behalf of any investor account for which we are
purchasing Securities to offer, sell or otherwise transfer such Securities prior
to the date which is two years after the later of the date of original issue and
the last date on which the Company or any affiliate of the Company was the owner
of such Securities, or any predecessor thereto (the "Resale Restriction
Termination Date") only (a) to the Company, (b) pursuant to a registration
statement which has been declared effective under the Securities Act, (c) so
long as the Securities are eligible for resale pursuant to Rule 144A, under the
Securities Act, to a person we reasonably believe is a qualified institutional
buyer under Rule 144A (a "QIB") that purchases for its own account or for the
account of a QIB and to whom notice is given that the transfer is being made in
reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the
United States within the meaning of Regulation S under the Securities Act, (e)
to an institutional "accredited investor" within the meaning of subparagraph
(a)(1), (2), (3) or (7) of Rule 501 under the Securities Act that is purchasing
for his own account or for the account of such an institutional "accredited
investor, or (f) pursuant to any other available exemption from the registration
requirements of the Securities Act, subject in each of the foregoing cases to
any requirement of law that the disposition of our property or the property of
such investor account or accounts be at all times within our or their control
and to compliance with any applicable state securities laws. The foregoing
restrictions on resale will not apply subsequent to the Resale Restriction
Termination Date. If any resale or other transfer of the Securities is proposed
to be made pursuant to clause (e) above prior to the Resale Restriction
Termination Date, the transferor shall deliver a letter from the transferee
substantially in the form of this letter to the warrant agent under the Warrant
Agreement pursuant to which the Securities were issued (the "Warrant Agent")
which shall provide, among other things, that the transferee is an institutional
"accredited investor" within the meaning of subparagraph (a)(1), (2), (3) or (7)
of Rule 501 under the Securities Act and that it is acquiring such Securities
for investment purposes and not for distribution in violation of the Securities
Act. The Warrant Agent and the Company reserve the right prior to any offer,
sale or other transfer prior to the Resale Restriction Termination Date of the
Securities pursuant to clause (e) or (f) above to require the delivery of a

                                       8
<PAGE>

written opinion of counsel, certifications, and or other information
satisfactory to the Company and the Warrant Agent.

     2.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) purchasing
for our own account or for the account of such an institutional "accredited
investor." and we are acquiring the Securities for investment purposes and not
with a view to, or for offer or sale in connection with, any distribution in
violation of the Securities Act and we have such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of our investment in the Securities, and we and any accounts for which we
are acting are each able to bear the economic risk of our or its investment for
an indefinite period.

     3.   We are acquiring the Securities purchased by us for our own account or
for one or more accounts as to each of which we exercise sole investment
discretion.

     4.   You, the Warrant Agent and your respective counsel are entitled to
rely upon this letter and you are irrevocably authorized to produce this letter
or a copy hereof to any interested party in any administrative or legal
proceeding or official inquiry with respect to the matters covered hereby.

                              Very truly yours,

                              (Name of Purchaser)

                              Date:
