the business of manufacturing and distribution of industrial absorbents (the

         B. The Company agrees to engage the Consultant and the Consultant
accepts the engagement with the Company ("Engagement"), subject to the terms and
conditions contained in this Consulting Agreement.

         NOW, THEREFORE, the parties hereby covenant that the foregoing recitals

         The Consultant shall serve as the business counselor to the Chairman of
the Board of the Company ("Chairman") and shall have such authority and such

as may be assigned to the Consultant from time to time by the Company's Board of
Directors (the "Board"). Consultant's Engagement includes the Company and its

3.       CONSIDERATION AND BENEFITS.

         3.1 Base Fee.

         The Company shall pay the Consultant an initial base fee, exclusive of
any bonuses, of $156,000 per annum ("Base Fee"). The Base Fee shall be increased
to $186,000 effective January 1, 2005 and $206,000 effective January 1, 2006. In
addition, the Base Fee shall be reviewed and increased upon the completion of
any Acquisition (whether by asset purchase or purchase of a majority of stock
interest) of any entity during the Engagement Period, or other mutually agreed
milestones. The amount of such increase shall be promptly determined by the
Board of Directors and made retroactive to the closing date of the Acquisition.
The Base Fee shall be payable at such intervals as salaries are paid by the
Company to its executive employees.

         3.2 Minimum Salary - Accrual

         The Consultant shall be limited to drawing down $6,000.00 per month of
his Base Fee until such time as the company reaches break-even in cash flow.
Base Fee due above $6,000.00 per month shall accrue to the Consultant and shall
be payable when the Company reaches break-even in cash flow, at which time the
Consultant shall draw down his full Base Fee. The accrual period shall be
limited to one year. Thereafter, if the company is not at break-even in cash
flow, the Base Fee due above $6,000.00 per month shall be waived by the
Consultant.

         3.3 Performance Based Bonus.

         The Consultant shall receive an annual bonus ("Bonus") pursuant to a
bonus system established for its Senior Management (as hereinafter defined)
whereby, on December 31, 2004, and on each anniversary thereof (each, a "Bonus
Year"), the Company shall set aside an amount equal to ten (10%) percent of its
earnings before interest, taxes, depreciation and amortization (the "Bonus
Pool"). Bonuses payable from the Bonus Pool shall be paid not later than 30 days
following the end of a Bonus Year. For the Bonus Year ending December 31, 2004,
the Company's Senior Management shall consist of Consultant and the Company's
Vice President/COO, who shall each share equally in the Bonus Pool. Commencing
with the Bonus Year ending December 31, 2004, and thereafter, the Senior Manager
may, in its discretion, add to the persons constituting Senior Management and
reallocate the Bonus Pool among such Senior Management, as redefined. In the
absence of any contrary action taken by the Board of Directors during a Bonus
Year, the computation and distribution of Bonuses to Senior Management shall be
that of the prior Bonus Year. Additionally, the Board reserves the right to
award Bonuses to the Consultant in excess of that prescribed above, in
recognition of his individual contributions, as and when it deems appropriate.

         3.4 Benefit Plans.

         During the Engagement Period, Consultant shall be entitled to
participate in all plans adopted for the general benefit of the Company's
executive employees, such as pension plans, medical plans, investment plans and
group or other insurance plans and benefits (including disability and life
insurance plans) to the extent that the Consultant is and remains eligible to
participate therein and subject to the eligibility provisions of such plans in
effect from time to time. At the request of Consultant, Company shall reimburse
Consultant for the cost of Consultant's medical insurance.

         3.5 Expenses.

         The Consultant shall be reimbursed for his reasonable out-of-pocket
expenses incurred in the performance of his duties upon submission of
appropriate evidence thereof in conformity with normal Company policy.

         3.6 Stock Options/Stock Grant.

         The Consultant shall be granted an option ("Option") to purchase a
number of shares equal to twelve (12%) of the issued and outstanding shares of
the common stock of the Company on a fully diluted basis ("Option Shares") at
the exercise price of $.01 per Option Share. The amount of shares included in
such options shall be calculated upon vesting, which shall be 1/2 upon execution
hereof and 1/2 on the first anniversary hereof. The Options shall contain
anti-dilution provisions relating to adjustments in the event that the Company,
among other things, declares stock dividends, effects forward or reverse stock
splits, or other financings. The Option shall expire seven (7) years from the
date of this Agreement. The Option shall be immediately exercisable and shall
remain exercisable during the Engagement Period and for a period of four (4)
years following termination of the Agreement. Payment of the Exercise Price of
the Option Shares being purchased may be made by a cashless exercise procedure
whereby the Option Shares issued upon exercise of the Option will be sold with
the Grantee receiving the difference between the Exercise Price and the sale
price, in cash, and the Company receiving the Exercise Price for the Option
Shares, in cash. The Option may be exercised in whole or in part. All Options
shall vest immediately upon Change in Control as defined below.

         3.7 Registration of Stock Underlying Options.

         (a) Piggyback Registration Rights. The Consultant shall have piggy back
registration rights, as to shares of the common stock underlying twenty-five
(25%) of the Options, subject to certain restrictions. If at any time Company
prepares and files one or more registration statements under the Securities Act
with respect to a public offering of its Company's equity securities, or of any
of the Company's securities held by its security holders (other than a
registration statement on Forms S-4, S 8, or similar form) the Company will
include in the registration statement information as is required, to permit a
resale of the shares of the common stock underlying twenty five percent 25% of
the Options. However, if, in the written opinion of the Company's managing
underwriter, if any, for such offering, the shares underlying the Warrant, when
added to the securities being registered by the Company or its selling security
holders, would exceed the maximum amount of securities that could be marketed
without otherwise materially and adversely affecting the entire offering, then
the Company may exclude shares required to be registered so that the total
number of securities to be registered is within the maximum number of shares
that, in the opinion of the managing underwriter, may be marketed without
otherwise materially and adversely affecting the entire offering.


                                       3

the Options. The Company will use its reasonable best efforts through its
officers, directors, auditors and counsel in all matters necessary or advisable
to file and cause to become effective such Registration Statement within one (1)
year of the Effective Date.

         c) The Company will bear all fees and expenses other than the fees and
expenses of shareholder's counsel incurred in the preparation and filing of one
or more registration statements and related state registrations, and the
furnishing of copies of the preliminary and final prospectuses. In connection
with filing of a registration statement, the Consultant may be required to
furnish certain information to the Company and must agree to indemnify the
Company, its officers, directors and controlling persons against any liabilities
or damages, including liabilities arising under the Securities Act, with respect
to any information the Investor provided in writing. The Company will agree to

liabilities under the Securities Act with respect to certain claims under the

written notice given at any time within one year after the occurrence of such

Exchange Act), directly or indirectly, of securities of the Company representing
thirty percent (30%) or more of the combined voting power of the Company's
outstanding securities then having the right to vote at elections of directors;
or

                  (b) the individuals who at the commencement date of the

will not apply where the Consultant gives the Consultant's explicit written
waiver stating that for the purposes of this Section 6.7(ii) a Change in Control
shall not be deemed to have occurred. The Consultant's participation in any
negotiations or other matters in relation to a Change in Control shall in no way
constitute such a waiver which can only be given by an explicit written waiver

Control of the Company or any "Attempted Change in Control," as hereinafter

                                       9
<PAGE>

operation and other information which the Company regards as confidential and in
the nature of trade secrets (collectively "Confidential Information"); provided,
however, Confidential Information shall not include information which (i) is
already in the possession of the Consultant prior to the date of this Agreement;

Information is valuable to the Company and that the Company could suffer damage
if any of the Confidential Information were improperly disclosed.

         The Consultant covenants and agrees that the Consultant will not, at
any time during or for a period of twelve (12) months after the termination of
the Consultant's relationship with the Company, reveal, divulge, or make known
to any person, firm or corporation, any Confidential Information made known to
the Consultant or of which the Consultant has become aware, regardless of
whether developed, prepared, devised or otherwise created in whole or in part by
the efforts of the Consultant, except and to the extent that such disclosure is
necessary to carry out the Consultant's duties for the Company. The Consultant
further covenants and agrees that the Consultant shall retain all Confidential
Information in trust for the sole benefit of the Company, and will not divulge
or deliver or show any Confidential Information to any unauthorized person
including, without limitation, any other employer of the Consultant, and the

purpose whatsoever.

period of twelve (12) months thereafter (or, if Consultant's Engagement is
terminated pursuant to Section 6.4 hereof, during the Severance Term), and
whether or not the Consultant shall be entitled to the payment of any
post-termination severance benefits described in Section 6.4 hereof, the
Consultant shall not, except as permitted under Section 7.3 hereof, (i) engage,

time the provisions of this Section 7.2 shall be determined to be invalid or
unenforceable, by reason of unreasonableness as to area, duration or scope of
activity, this Section 7.2 shall be considered divisible and shall become and be
immediately amended to only such area, duration and scope of activity as shall
be determined to be reasonable and enforceable by the court or other body having
jurisdiction over the matter; and the Consultant agrees that this Section 7.2 as
so amended shall be valid and binding as though any invalid or unenforceable
provision had not been included herein.

         7.3 Exclusivity.

         During the Engagement Period, the Consultant shall devote substantially
his full time to the business of the Company, shall faithfully serve the
Company, shall in all respects conform to and comply with the lawful and
reasonable directions and instructions given to him by the Board in accordance
with the terms of this Agreement, shall use his best efforts to promote and
serve the interest of the Company and shall not engage in any other business
activity, whether or not such activity shall be engaged in for pecuniary profit,
except that the Consultant may (i) participate in the activities of professional
trade organizations related to the business of the Company and its subsidiaries,
(ii) engage in personal investing activities of unrelated businesses and (iii)
with the written consent of the Board, which shall not be withheld unreasonably,
own up to five (5%) percent of the outstanding capital stock or profits interest
of any competing Business, provided that the activities set forth in these
clauses (i), (ii) and (iii), either singly or in the aggregate, does not
interfere in any material respect with the services to be provided by the
Consultant hereunder.

         7.4 Due Performance By Company.

         All terms and provisions of this Section 7 are subject to the Company's
due performance of all obligations on its part to be performed.

8.       ENFORCEMENT.

         The Consultant acknowledges that the Company will suffer substantial
and irreparable damages not readily ascertainable or compensable in terms of
money in the event of the breach of any of the Consultant's obligations under
Section 7. The Consultant agrees that the Company, in addition to any other
remedies (including damages) provided by law, shall have the right and remedy to
have such provisions specifically enforced by any court having equity
jurisdiction upon due notice to the Consultant. The rights and remedies set
forth in this Section 8 shall be in addition to, and not in lieu of, any other
rights and remedies available to the Company under law or equity. Should it
become necessary for any party to institute legal action to enforce the terms
and conditions of this Agreement, the successful party will be awarded
reasonable attorneys' fees at all trial and appellate levels, expenses and
costs.

9.       INDEMNITY.

                  9.1 The Consultant shall be covered by the Articles of
Incorporation and/or the Bylaws of the Company with respect to matters occurring
on or prior to the date of termination of the Consultant's Engagement with the
Company, subject to all the provisions of Delaware and Federal law and the
Articles of Incorporation and Bylaws of the Company then in effect. Such
reasonable expenses, including attorneys' fees, that may be covered by the
Articles of Incorporation and/or Bylaws of the Company shall be paid by the

                                       11
<PAGE>

Company on a current basis in accordance with such provision, the Company's
Articles of Incorporation and Delaware law. To the extent that any such payments
by the Company pursuant to the Company's Articles of Incorporation and/or Bylaws
may be subject to repayment by the Consultant pursuant to the provisions of the
Company's Articles of Incorporation or Bylaws, or pursuant to Delaware or
Federal law, such repayment shall be due and payable by the Consultant to the
Company within twelve (12) months after the termination of all proceedings, if
any, which relate to such repayment and to the Company's affairs for the period
prior to the date of termination of the Consultant's Engagement with the Company
and as to which Consultant has been covered by such applicable provisions.

         9.2 The Company hereby agrees to indemnify Consultant and hold
Consultant harmless from and against all claims and damages (including
reasonable attorney's fees) arising out of or relating to any personal
guarantees given by Consultant to secure obligations of the Company. Company's
obligations under this section shall survive the termination of this Agreement
and the termination of Consultant's Engagement with the Company. The Company
further agrees that, if Consultant is terminated without cause during the term
of this Agreement, Company will exercise best efforts to relieve Consultant from
his guaranteed obligations and, failing such efforts, to attempt to refinance
the indemnified obligation if it is commercially reasonable to do so.

10.      Withholding.

         Anything to the contrary notwithstanding, all payments required to be
made by the Company hereunder to the Consultant or the Consultant's estate or
beneficiaries shall be subject to the withholding of such amounts, if any,
relating to tax and other payroll deductions as the Company may reasonably
determine it should withhold pursuant to any applicable law or regulation. In
lieu of withholding such amounts, the Company may accept other arrangements
pursuant to which it is satisfied that such tax and other payroll obligations
will be satisfied in a manner complying with applicable law or regulation.

         11. Certain Tax Matters. The Company shall indemnify and hold the
Consultant harmless from and against (i) the imposition of excise tax (the
"Excise Tax") under Section 4999 of the Internal Revenue Code of 1986, as
amended (or any successor provision thereto, the "Code"), on any payment made
under this Agreement (including any payment made under this paragraph) and any
interest, penalties and additions to tax imposed in connection therewith, and
(ii) any federal, state or local income tax imposed on any payment made pursuant
to this paragraph. The Consultant shall not take the position on any tax return
or other filing that any payment made under this Agreement is subject to the
Excise Tax, unless, in the opinion of independent tax counsel reasonably
acceptable to the Company, there is no reasonable basis for taking the position
that any such payment is not subject to the Excise Tax under U.S. tax law then
in effect. If the Internal Revenue Service makes a claim that any payment or
portion thereof is subject to the Excise Tax, at the Company's election, and the
Company's direction and expense, the Consultant shall contest such claim;


                                       12
<PAGE>

provided, however, that the Company shall advance to the Consultant the costs
and expenses of such contest, as incurred. For the purpose of determining the
amount of any payment under clause (ii) of the first sentence of this paragraph,
the Consultant shall be deemed to pay federal income taxes at the highest
marginal rate of federal income taxation applicable to individuals in the
calendar year in which such indemnity payment is to be made and state and local
income taxes at the highest marginal rates of taxation applicable to individuals
as are in effect in the jurisdiction in which the Consultant is resident, net of
the reduction in federal income taxes that is obtained from deduction of such
state and local taxes.

11.      MISCELLANEOUS PROVISIONS.

         11.1 Entire Agreement; Prior Agreement Terminated.

         This Agreement set forth the entire agreement and understanding between

Company's business and/or assets ("Change of Ownership"). The Company shall
require any successor, by agreement in form and substance reasonably
satisfactory to the Consultant, to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be

         11.4 Waiver.

         The failure of either party at any time or times to require performance
of any provision hereof in no manner shall affect the right at a later time to
enforce the same. No waiver by either party of a breach of any term or covenant
contained in this Agreement, whether by conduct or otherwise, in any one or more
instances, shall be deemed to be or construed as a further or continuing waiver
of any such breach or a waiver of any other term or covenant contained in this
Agreement.

and shall be conducted by a single arbitrator. The arbitration shall be
conducted by a single arbitrator to be selected by 2 (or 3) independent
arbitrators, one each to be selected by each party to the dispute. The written
decision of the arbitrator so selected shall be binding, final and conclusive on
the parties. The fees and expenses of the arbitration will be shared equally by
the disputing parties. The prevailing party in any arbitration (subject to the
discretion of the arbitrator) shall recover its expenses and costs including
reasonable attorney's fees from the other party. The parties knowingly and
voluntarily agree to enter into this arbitration clause and waive any rights
that might otherwise exist to request a jury trial or other court proceeding.

         11.8 Assignability.

         This Agreement and the Consultant's rights and obligations hereunder,
may not be assigned by the Consultant. Subject to Consultant's documentary
approval rights as provided in Section 9.3, the Company may assign its rights,

the parties and their respective legal representatives, heirs, permitted
