behalf of the Company and orders obtained shall be at prices authorized by the Company. All prices
for Services within the scope of this Agreement shall be subject to revision in accordance with the

case and shall not be used for any future sale without the Company’s written authorization.

6. Order Acceptance/Rejection.

(a) The Company has the right, in its sole discretion, to accept or reject (in whole or in
part) any or all orders from Customers, including without limitation, orders that, in the sole
opinion of the Company, involve questionable credit risks or orders which for any reason are deemed
unacceptable to the Company. the Company shall not be liable to Representative for loss or damage
caused by the Company’s inability or refusal for any reason to accept an order to provide Services
and Representative shall have no right to any indemnification or other compensation whatsoever on

7. Compensation.

(a) In consideration of Representative’s performance of its duties as described herein, the
Company shall, during the Term, (i) pay Representative Nine Hundred Dollars ($900) per month per
Principal, during each month in which each of the Principals continues to be employed by
Representative and continues to perform his obligations contemplated by this Agreement (the “Fixed
Monthly Payment”), with the first such Fixed Monthly Payment being prorated for the unexpired
portion of the first month in which this Agreement becomes effective, payable within five (5)
business days after the date of this Agreement and all subsequent Fixed Monthly Payments payable on
or before the 5th day of each calendar month thereafter during the Term and (ii) pay
Representative commissions (“Commissions”) based on the amount of the Company’s Adjusted Profit
during the Term, as set forth herein. The Commissions payable to Representative shall be equal to
(x) for the period commencing on the Effective Date and continuing through and including June 30,
2008, five percent (5%) of the Adjusted Profit for such period and (y) for the period commencing
July 1, 2008 and continuing through and including the Termination Date, twenty-five percent (25%)
of the Adjusted Profit for such period. In clarification of the Fixed Monthly Payment, for
example, in any month where only three of the Principals remain employed by Representative and
continue to perform the obligations contemplated hereby, the aggregate Fixed Monthly Payment will
be $2,700.

(b) Subject to the Advance Commission Limit (as defined below), Commissions with respect to
Net Sales in a given month shall be paid by the Company to Representative on or prior to the
twentieth (20th) day of the next following month in order to allow time for the
Company’s books of account for the month to be closed. Commissions will be deemed paid as advances
on Net Sales to the extent that receivables related to such sales remain outstanding and
uncollected at the time the Commissions are paid, but Commissions will not be deemed earned until
the accounts receivable related to such sales have actually been collected. No Commissions shall
be earned on sales to the extent any receivables related to such sales have not been collected
within one hundred eighty (180) days after the date of the applicable invoice (“Delinquent
Accounts”) and any Commissions that were advanced against Delinquent Accounts shall be, at the
election of the Company in its sole discretion, either credited back to the Company against future
Commissions earned or directly reimbursed to the Company by Representative upon demand by the
Company. In no event shall Representative be entitled to Commissions on any Delinquent Accounts,
even if such receivables are ultimately collected. On or about the 15th day of each
calendar month, Representative shall submit to the Company an estimate of its actual Net Sales
during such initial 15-day period in such month and the good faith estimated transportation and
disposal costs associated therewith, and the Company shall estimate the Adjusted Profit related to
such Net Sales (the “Estimated Interim Profit”). Subject to the Advance Commission Limit, the
Company shall pay Representative twenty percent (20%) of such Estimated Interim Profit within five
(5) days following such submission by Representative. At the time Commissions are paid as
contemplated by the first sentence of this Section 7(b), any advances to Representative based on
such Estimated Interim Profit shall be reconciled and the amount of Commissions payable adjusted to
reflect the prior payment of advances on such Estimated Interim Profit. Commissions advanced on
uncollected sales (including, without limitation, amounts advanced with respect to the Estimated
Interim Profit) shall not at any time, in the aggregate, exceed Two Hundred Thousand Dollars
($200,000.00) (the “Advance Commission Limit”) and the Company shall not be obligated to advance
Representative unearned Commissions in excess of the Advance Commission Limit notwithstanding
anything to the contrary contained herein. The Company shall deliver with each Commission Payment,
a statement describing the calculation of the Adjusted Profit and Commissions.

 

7

 

(c) Periodically, but not less than annually, the Company shall reconcile Commissions paid to
Representative against Commissions earned by Representative based upon the Adjusted Profit as
calculated by
the Company for the applicable period. If such reconciliation indicates that Commissions paid
to Representative are greater than Commissions earned by Representative, the amount of the
overpayment shall be, at the election of the Company in its sole discretion, either credited back
to the Company against future Commissions earned or directly reimbursed to the Company by
Representative upon demand by the Company. If such reconciliation indicates that Commissions paid
to Representative are less than Commissions earned by Representative, then the amount of the
underpayment shall be paid by the Company to Representative. In any event, the Company shall
deliver to Representative a statement describing such reconciliation.

(d) The Company shall not deduct for taxes, assessments or other charges. However, if the
Company shall be required under the laws of any jurisdiction to deduct from any payments made to
Representative any income taxes, or withholding taxes or fees in lieu of income taxes which may be
levied against Representative, then the Company shall so deduct such taxes or fees, provided the
Company promptly furnishes to Representative tax receipts or other documentary evidence, evidencing
payment of such taxes or fees to the appropriate governmental authority or agency.

(e) Any overpayments of Commissions to Representative resulting from refunds, settlements of
claims, other adjustments with Customer, or any other cause, similar or dissimilar, may be deducted
from any Commissions otherwise due Representative or in the alternative shall be repaid by
Representative immediately upon demand of the Company, as the Company shall determine.

8. Long Island Office. The Company shall promptly following the execution of the Agreement
open an office (the “Long Island Office”) in leased space at a location identified by
Representative on Long Island, New York, that is reasonably acceptable to the Company.
Representative shall have the right to occupy and use such office in connection with the
performance of Representative’s obligations under this Agreement. Representative agrees to comply
with any and all terms of any applicable lease agreement and rules and regulations for the premises
and any applicable laws, including, without limitation, those related to occupancy of the leased
premises. The Company shall be solely responsible for paying all rent for the Long Island Office.

9. Term and Termination. Representative’s appointment and position as a sales representative
pursuant to this Agreement shall commence on the date hereof and continue until December 31, 2012
(the “Initial Term”). The Initial Term shall thereafter automatically renew on the same terms for
additional two-year terms (each, a “Renewal Term”) unless either party gives the other party
written notice of non-renewal at least ninety (90) days prior to the end of the Initial Term or the
then current Renewal Term, as the case may be. Representative’s appointment and position as a
sales representative pursuant to this Agreement shall be terminable as follows:

(a) by either party upon breach by the other party of any of the covenants or agreements
contained herein, provided that, if such breach is capable of being cured Representative’s
appointment as a sales representative hereunder may not be terminated unless the breach remains
uncured for a period of ten (10) days after the non-breaching party provides written notice of the
breach to the breaching party;

(b) automatically without prior notice, demand or judicial notice upon the occurrence of any
of the following events:

(i) if Representative enters into voluntary or involuntary bankruptcy, or ceases to make

business, whether in whole or in part, for the benefit of its creditors,

(iii) if a receiver or trustee is appointed to take over or administer or conduct all or any
part of the business or property of Representative, or

(iv) if there is a change in control of Representative or transfer of substantially all of the
business assets of Representative or a merger or reorganization which, in the Company’s opinion,
affects the
relationship between the Company and Representative (Representative shall give the Company
notice at least ten (10) days before the occurrence of any such event);

 

8

 

(c) by the Company if one or more Principals (i) is convicted of a felony or crime of moral
turpitude, (ii) commits an act of theft, embezzlement or act of fraud or dishonesty with respect to

Representative to carry out its responsibilities and duties hereunder or which adversely affects
the Company, the health, safety or welfare of its employees or its reputation, (iv) willfully
violates any material rules, policies or procedures of the Company in connection with causing
Representative to perform its duties hereunder, (v) engages in other misconduct which is harmful to

Termination Date, and (ii) such orders are for Services to be rendered not more than thirty (30)
days after the Termination Date, and (iii) the Company is paid in full within one hundred eighty

acknowledges that no Commissions whatsoever will be due to Representative with respect to any order
or portion of an order which does not meet each and all of the foregoing requirements.

(b) Notwithstanding the foregoing, if this Agreement is terminated by the Company as a result
of Representative’s failure to comply with all of its obligations set forth in Subsection 10(c) and
Sections 13 and 14 below, Representative shall forfeit all outstanding accrued and unpaid
commissions including Commissions which would have otherwise been payable to Representative
pursuant to section 10(a) above. Representative and the Company agree that such forfeiture is in
the nature of liquidated damages, is reasonable and is not in the nature of a penalty, provided
that, notwithstanding the foregoing, the PEI Companies shall also have the right to injunctive
relief set forth in Section 15 hereof.

(c) Representative shall submit to the Company at least three (3) days before the Termination
Date, a complete list of quotations outstanding, full information on each, including current status
as well as such other information concerning the Customers as the Company may reasonably request.

(d) Upon expiration or termination of this Agreement in any manner, and except for the
obligations set forth above in this Section 10, the Company shall not be liable to Representative
either for compensation or for direct, incidental, special, exemplary, consequential, or punitive
damages of any kind or character whatsoever, whether on account of the loss by Representative of
present or prospective profits or expenditures, investments or commitments made in connection
therewith or in connection with the establishment, development or maintenance of Representative’s
business.

11. Reimbursement of Legal Fees. Provided that (i) Representative is not in continuing breach
of this Agreement, (ii) the appointment of Representative as a sales representative hereunder has
not been terminated by the Company pursuant to Section 9(a), 9(c) or 9(d) above or automatically

Representative and actively involved in Representative’s business and causing Representative to
perform its obligations under this Agreement, the Company shall pay any reasonable attorneys’ fees
that are incurred by Representative and/or any of the Principals in connection with the defense of
any legal proceedings, lawsuits or claims asserted against any of them by Clean Earth, Inc. arising
from this Agreement or the Acquisition Agreement, provided, however, that any award of damages will
be borne by Principals and/or Representative. Such legal fees will be paid within thirty (30) days
after the Company’s receipt of the legal bill and confirmation with the Principals and/or
Representative, as applicable, that the amount of legal fees is not in dispute.

 

9

 

The Company’s sole obligation pursuant to this Section 11 is to pay reasonable attorneys’ fees
incurred by Representative and/or the Principals in accordance with this Section 11, subject at all
times to the conditions and limitations set forth herein. Notwithstanding the foregoing, the
Company shall have no obligation to pay any such legal fees in the event that Representative has
breached its representations and warranties set forth in Section 18(b) hereof and the restrictive
covenants described in Section 18(b) gave rise to the lawsuit or other proceeding and, in the event
the Company has paid any such legal fees, Representative shall or shall cause Principals to
reimburse Representative for the amount of such legal fees paid by the Company upon demand by the
Company.

12. Finder’s Fee Program. If Representative identifies and introduces opportunities for PEI
that are acquired by PEI, PEI will pay to Representative a finder’s fee equal to one percent (1.0%)
of the aggregate cash and stock paid by PEI for such acquisition opportunities.

13. Confidentiality. Each of the Representative Parties recognizes and acknowledges that by
reason of its or his present and future service to the Company it or he has been and will be given
access to confidential and/or proprietary information of the PEI Entities, including, without
limitation, information and knowledge pertaining to innovations, designs, ideas, plans, trade
secrets, proprietary information, sales and profit figures, customer and client lists (including,
without limitation, the Persons listed on the Prospect List), and relationships between certain PEI
Entities, customers, clients, suppliers and others who have business dealings with PEI Entities
(collectively, “Confidential Information”). Each of the Representative Parties acknowledges that
such Confidential Information is a valuable and unique asset of the applicable PEI Entities and
each of the Representative Parties covenants and agrees that it or he will at all times keep
confidential such Confidential Information, and will not at any time during or after the expiration
or earlier termination of this Agreement (a) disclose, in whole or in part, any Confidential
Information to any person, firm, corporation, association or other entity for any reason or purpose
whatsoever unless authorized in writing to do so by the Company, or (b) use any Confidential
Information for its own purpose or for the benefit of any person, firm, corporation, association or
other entity other than the Company; except in the proper performance of sales representative
services under this Agreement as instructed by the Company. Upon the expiration or earlier
termination of the term of this Agreement, or at any other time upon request of the Company, each
of the Representative Parties shall promptly deliver to the Company, all property, equipment, sales
literature, promotional materials, other records, documents and Materials relating to any PEI
Entity or the Services (including information and documents stored on computers, disks or any other
medium), regardless of whether or not such information is Confidential Information. Representative
and AEG shall cause their respective officers, agents, employees and other representatives to be
bound by the foregoing confidentiality provisions, and agrees to be responsible for any breach
thereof by any such officers, agents, employees or other representatives. The provisions of this
Section 13 shall survive the expiration or earlier termination of the Term of this Agreement.
Confidential Information does not include information which: (a) is known to any Representative
Party at the time of disclosure to such Representative Party by the Company as evidenced by such
Representative Party’s written records, (b) has become publicly know and made generally available
through no wrongful act of a Representative Party, or (c) has been rightfully received by a
Representative Party from a third party who is authorized to make such disclosure.

14. Non-Competition; Non-Solicitation; Non-Disparagement. Each of the Representative Parties
agrees that it or he will not except with the Company’s prior written consent, during the
Restricted Period, directly or indirectly:

(a) for its own benefit or for the benefit of any Person in any business in competition with
the Business, canvas, contact, solicit, contract with or accept any business from any customer or
prospective customer of a PEI Entity, including, without limitation, any Person on the Prospect
List;

(b) directly or indirectly request or advise any past, present or future Customers (a future
Customer being defined as one that has been actively solicited by any PEI Entity prior to the
cessation of Representative’s engagement as a sales representative of the Company) of such PEI
Entity, including, without limitation, the Persons listed on the Prospect List, to withdraw,
curtail or cancel their business with such PEI Entity;

(c) render services to, become engaged as an independent contractor by, own or have a
financial interest in (either as a partner, joint venturer, owner, stockholder, independent
contractor or any other role) any business which is engaged in the same, similar or competitive
business as the Business, within a 125 mile radius
of Times Square, New York, except that nothing herein shall prohibit the Representative
Parties from owning up to 1% of the outstanding shares in a publicly traded corporation;

 

10

 

(d) induce, offer, assist, encourage or suggest (i) that another business or enterprise offer
employment to or enter into a business affiliation with any Person that is or was an employee,
agent or representative of any PEI Entity within the one (1) year period prior to such solicitation
or employment, or (ii) that any PEI Entity employee, agent or representative terminate his
employment or business affiliation with such PEI Entity;

(e) hire, employ or contract with any Person that is or was an employee, agent or
representative of any PEI Entity within one (1) year period prior to such solicitation or
employment; or

(f) disparage any of the PEI Entities or any of their respective directors, officers,
employees or agents.

15. Injunctive Relief.

(a) The parties agree that any breach by any Representative Party of the covenants and
agreements contained in Sections 13 and 14 will result in irreparable injury to the applicable PEI
Entities for which money damages could not adequately compensate the PEI Entities, and, therefore,
in the event of any such breach, the PEI Entities shall be entitled (in addition to any other
rights and remedies which it may have at law or in equity) to have an injunction, whether
preliminary, mandatory, temporary or permanent issued by any competent court of equity enjoining
and restraining such Representative Party and/or any other Person involved therein from continuing
such breach without the necessity of showing any particular injury or damage or posting of any bond
or other security. The existence of any claim or cause of action which any Representative Party
may have against any PEI Entity or any other Person shall not constitute a defense or bar to the
enforcement of such covenants. The covenants contained in Sections 13 and 14 are independent of
all other covenants between the parties hereto and shall survive the termination of this Agreement.

(b) Each of the Representative Parties and the Company agree and acknowledge that the
duration, scope and geographic area of the covenant not to compete described in Section 14 above is
fair, reasonable and necessary in order to protect the goodwill and other legitimate interests of
the PEI Entities, that adequate consideration has been provided to Representative. If, however,
any portion of the covenants or agreements contained herein, or the application thereof, is
construed to be invalid or unenforceable, then the other portions of such covenant(s) or
agreement(s) or the application thereof shall be considered divisible and not be affected and shall
be given full force and effect without regard to the invalid or unenforceable portions. If any
covenant or agreement herein is held to be unenforceable because of the area covered, the duration
thereof, or the scope thereof, then the court making such determination shall have the power to
reduce the area and/or duration and/or limit the scope thereof, and the covenant or agreement shall
then be enforceable in its reduced form.

16. Right of First Refusal. PEI shall have rights of first refusal as described herein to
provide all transportation and disposal services to the Company on sales generated by
Representative; provided, however, that for purposes of calculating Adjusted Profit, if PEI’s cost
of providing such transportation and disposal services is more than ten percent (10%) in excess of
the bona fide competitive bid (“Bona Fide Competitive Bid”) for such services by a third party
having the financial wherewithal, operational capacity and bonding capability (if required) to
perform the services, and PEI desires to perform the services it may do so, provided that an
adjustment shall be made to the Adjusted Profit calculation in the amount by which PEI’s charge for
such services exceeds 110% of such other competitive bid (the “Right of First Refusal Adjustment
Amount”) to avoid adversely affecting Commissions payable to Representative. If Representative
obtains a Bona Fide Competitive Bid and desires to accept it, Representative shall provide written
notice to the Company and PEI of such Bona Fide Competitive Bid, including a copy of the Bona Fide
Competitive Bid, the name of the bidder and its principal office address and telephone number and
information regarding the financial wherewithal, operational capacity and bonding ability (if
applicable) of the bidder. PEI shall have a period of twenty four hours from the date and time
such notice is received by PEI to notify Representative whether or not it desires to exercise its
right of first refusal pursuant to this Section 16. If PEI notifies Representative in accordance
with the terms of this Agreement that it desires to exercise its right of first refusal, then
Representative may not cause the Company to accept the Bona Fide Competitive Bid and PEI shall be engaged to perform such services.

 

11

 

If PEI notifies the Company that it does
not intend to exercise its right of first refusal or if PEI fails to provide such notice to
Representative within such twenty four hour period, then Representative may accept the Bona Fide
Competitive Bid on behalf of the Company, but only on the same terms and conditions that were
provided in the notice to PEI. If any of the terms of the Bona Fide Competitive Bid change, then
Representative shall provide written notice to PEI and the Company of the changed terms and PEI
shall again have the right of first refusal described herein with respect to the Bona Fide
Competitive Bid, as amended or modified.

17. Common Stock Opportunities. PEI will endeavor to have the Board of Directors of PEI
establish opportunities for Representative to obtain additional common stock opportunities after
the second year of the Term (i.e., after the end of the twenty-four month period following the
Effective Date), tied to future performance by Representative.

18. No Violation of Third Party Proprietary Rights, etc.

(a) Representative represents and warrants to the Company (i) that none of the information and
materials in its possession and/or the possession of any of the Principals, or that from time to
time may come into their possession, which may from time to time be used by Representative and/or
the Principals acting on behalf of Representative in the performance of this Agreement, including,
without limitation, any and all lists of Persons identified as prospective customers that were
obtained by or from any of the Principals, is considered proprietary or confidential information of
any other Person, including, without limitation, Clean Earth, Inc. or any other former employer of
any of the Principals, nor was such information acquired by Representative or the Principals in
violation of any proprietary rights of any other Person, including, without limitation, Clean
Earth, Inc. or any other former employer of any of the Principals and (ii) that Representative and
the Principals have the right to use all such information in furtherance of Representative’s duties
under this Agreement. The use of such information will not infringe or otherwise violate the
proprietary or other rights of any other Person, including, without limitation, Clean Earth, Inc.
or any other former employer of any of the Principals. No Person, including, without limitation,
Clean Earth, Inc. or any other former employer of any of the Principals, will have any claim for
monetary damages or equitable relief (including injunctive relief) against any Principal,
Representative, the Company, PEI or any other PEI Entity for misappropriation of proprietary
information or under any other legal theory, as a result of or related to Representative and/or any
Principal using such information in the performance of Representative’s duties under this
Agreement.

(b) Representative further represents and warrants to the Company that Principals’ ownership
interest in Representative, Representative’s entry into this Agreement and the performance of this
Agreement by Representative and Principals acting on behalf of Representative does not violate any
restrictive covenants to which Representative or to any Principal is subject or bound, including,
without limitation, any covenant not-to-compete, and that neither Representative nor any Principal
is prohibited from performing or causing Representative to perform Representative’s obligations
under this Agreement due to such restrictive covenants.

(c) Representative represents and warrants to the Company that neither it nor any of the
Principals are presently, directly or indirectly, employed by, serving as an independent contractor
for, or joint venturer, partner, or director of Clean Earth, Inc., or any other company in
competition with the Business.

(d) Representative shall indemnify, defend and hold harmless the Company from and against any
and all losses, expenses, costs, damages, claims, actions, lawsuits and proceedings, including,
without limitation, reasonable attorneys’ fees, arising from or related to any breach of the
