prior to such consummation, (3) the Required Investors notify the Company, in writing, that they

shares of Preferred Stock in whole but not in part. In the event of such an optional redemption,

holder pursuant to the Certificate of Designations. The Additional Shares shall be identical to
all other shares of Preferred Stock except that the “Original Issue Date” (as defined in the
Certificate of Designations) with respect to such shares shall be the date such Additional Shares
are actually issued. In such cases, the number of Additional Shares to be issued as payment of
such previously accreted dividends shall be equal to the amount of accreted dividends being paid by

be reduced by the amount of the accreted dividend paid by the issuance of Additional Shares
pursuant to this Section 2.9.

2.10 Pro Rata Treatment.

If any Investor shall, by exercising any right of setoff or counterclaim or otherwise, obtain
payment in respect of the Preferred Stock, the Warrant or other Obligations hereunder resulting in
such Investor’s receiving payment of a proportion of the aggregate amount of the Liquidation Value
of the Preferred Stock held by it and or other such Obligations greater than its pro rata share
thereof as provided herein (except where such excess payment is received as a result of the
Inventors differing decisions with respect to redeeming their shares of Preferred Stock where such
redemption is at the election of individual Investors), then the Investor receiving such greater
proportion shall (a) notify the other Investors of such fact, and (b) purchase (for cash at face
value) Obligations of the other Investors, or make such other adjustments as shall be equitable, so
that the benefit of all such payments shall be shared by the Investors ratably in accordance with
the Liquidation Value of their respective shares of Preferred Stock and other amounts owing them,
provided that (i) if any such Obligations are purchased and all or any portion of the
payment giving rise thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the provisions of this
Section shall not be construed to apply to (x) any payment made by the Company pursuant to and in
accordance with the express terms of this Agreement or (y) any payment obtained by an Investor as
consideration for the assignment of or sale of its Preferred Stock or Warrant to any assignee or
participant, other than to the Company or any Subsidiary thereof (as to which the provisions of
this Section 2.10 shall apply). The Company consents to the foregoing and agrees, to the extent it
may effectively do so under applicable law, that any Investor acquiring an Obligation pursuant to
the foregoing arrangements may exercise against the Company rights of setoff and counterclaim with
respect to such Obligation as fully as if such Investor were a direct obligee of the Company in the
amount of such Obligation. If under any applicable bankruptcy, insolvency or similar law, any
Investor receives a secured claim in lieu of a setoff to which this Section 2.10 applies, such
Investor shall, to the extent practicable, exercise its rights in respect of such secured claim in
a manner consistent with the rights of the Investors entitled under this Section 2.10 to share in
the benefits of any recovery on such secured claim.

change the basis of taxation of payments to such Investor in respect thereof (except for
Indemnified Taxes or Other Taxes covered by Section 2.12 and the imposition of, or any change in
the rate of, any Excluded Tax payable by such Investor); or

(iii) impose on any Investor any other condition, cost or expense affecting this Agreement;

and the result of any of the foregoing shall be to increase the cost to such Investor, or to reduce
the amount of any sum received or receivable by such Investor hereunder, then, upon request of
such Investor, the Company will pay to such Investor, as the case may be, such additional amount or
amounts as will compensate such Investor, as the case may be, for such additional costs incurred or
reduction suffered.

(b) If any Investor determines in good faith and in the exercise of its reasonable business

reducing the rate of return on such Investor’s capital or on the capital of such Investor’s holding
company, if any, as a consequence of this Agreement or such Investor’s purchase or ownership of the
Preferred Stock to a level below that which such Investor or such Investor’s holding company could
have achieved but for such Change in Law (taking into consideration such Investor’s and the
policies of such Investor’s holding company with respect to capital adequacy), then from time to
time the Company will pay to such Investor such additional amount or amounts as will compensate
such Investor or such Investor’s holding company for any such reduction suffered.

(c) A certificate of an Investor setting forth the amount or amounts reasonably determined by
such Investor in good faith necessary to compensate such Investor or its holding company, as the
case may be, as specified in Section 2.11(a) or 2.11(b) and delivered to the Company shall be
conclusive absent manifest error. The Company shall pay such Investor the amount shown as due on
any such certificate within ten days after receipt thereof.

 

24

 

(d) Failure or delay on the part of any Investor to demand compensation pursuant to the
foregoing provisions of this Section shall not constitute a waiver of such Investor’s right to
demand such compensation, provided that the Company shall not be required to compensate an
Investor pursuant to the foregoing provisions of this Section for any increased costs incurred or
reductions suffered more than nine months prior to the date that such Investor notifies the Company
of the Change in Law giving rise to such increased costs or reductions and of such Investor’s
intention to claim compensation therefor (except that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the nine-month period referred to above shall be
extended to include the period of retroactive effect thereof).

(e) Notwithstanding anything to the contrary elsewhere in this Agreement, if any Change in Law
results in an increase in payments by Company to any Investor hereunder, the Company may
immediately redeem the Preferred Stock of such Investor in whole or in part at a Redemption Price
calculated in the same manner as optional redemptions are conducted pursuant to Section 2.7(c)
hereof.

2.12 Taxes.

(a) Any and all payments by or on account of any obligation of the Company hereunder or under
any other Investment Document shall be made free and clear of and without reduction or withholding
for any Indemnified Taxes or Other Taxes, provided that if the Company shall be required by
applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then
(i) the sum payable shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section) the Investor
receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Company shall make such deductions and
(iii) the Company shall timely pay the full amount deducted to the relevant Governmental Authority
in accordance with applicable law.

(b) Without limiting the provisions of Section 2.12(a), the Company shall timely pay any Other
Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Company shall indemnify each Investor within 10 days after demand therefor, for the
full amount of any Indemnified Taxes or Other Taxes imposed or asserted on or attributable to
amounts payable in respect of the Obligations (including Indemnified Taxes or Other Taxes imposed
or asserted on or attributable to amounts payable under this Section) paid by such Investor and any
penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority. A certificate as to the amount of such payment or liability
delivered to the Company by an Investor shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the
Company to a Governmental Authority, the Company shall deliver to the applicable Investors the
original or a certified copy of a receipt issued by such Governmental Authority evidencing such
payment, a copy of the return reporting such payment or other evidence of such payment reasonably
satisfactory to such Investors.

 

25

 

(e) Any Foreign Investor that is legally entitled to and desires to obtain the benefit of an
exemption from or reduction of withholding tax for United States federal income tax purposes, with
respect to payments hereunder or under any other Investment Document shall deliver to the Company,
at the time or times prescribed by applicable law or reasonably requested by the Company, such
properly completed and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate of withholding. In addition, any
Investor, if requested by the Company, shall deliver such other documentation prescribed by
applicable law or reasonably requested by the Company as will enable the Company to determine
whether or not such Investor is subject to backup withholding or information reporting
requirements.

Without limiting the generality of the foregoing, any Foreign Investor shall deliver to the
Company on or prior to the date on which such Foreign Investor becomes an Investor under this
Agreement (and from time to time thereafter upon the request of the Company, but only if such
Foreign Investor is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for
benefits of an income tax treaty to which the United States is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Investor claiming the benefits of the exemption for portfolio
interest under Section 881(c) of the Code, (x) a certificate to the effect that such Foreign
Investor is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10
percent shareholder” of the Company within the meaning of Section 881(c)(3)(B) of
the Code, or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the
Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by applicable law as a basis for claiming exemption from or a
reduction in United States Federal withholding tax duly completed together with such supplementary
documentation as may be prescribed by applicable law to permit the Company to determine the
withholding or deduction required to be made.

(f) If any Investor receives a refund of any Taxes or Other Taxes as to which it has been
indemnified by the Company or with respect to which the Company has paid additional amounts
pursuant to this Section, such Investor shall promptly pay to the Company an amount equal to such
refund (but only to the extent of indemnity payments made, or additional amounts paid, by the
Company under this Section with respect to the Taxes or Other Taxes giving rise to such refund),
net of all out-of-pocket expenses of such Investor and without interest (other than any interest
paid by the relevant Governmental Authority with respect to such refund), provided that the
Company, upon the request of such Investor agrees to repay the amount paid over to the Company
(plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to
such Investor in the event such Investor is required to repay such refund to such Governmental
Authority.

 

26

 

(g) Notwithstanding the foregoing, the Company may, at any time, challenge the imposition of
any Taxes or Other Taxes subject to payment or indemnification by Company hereunder and, without
limiting the foregoing, pursue a refund of any such Taxes or Other Taxes. Any such amounts
recovered, including, any interest, penalties or other amounts, shall be the property of the
Company. Any Investor with respect to whom any such challenge or refund relates agrees to
reasonably cooperate, at the sole expense of the Company, with the Company in the pursuit of such
challenge or refund including, without limitation, permitting such challenge or refund request to
be brought in the name of such investor and providing to the Company or its designee a limited
power of attorney with respect thereto. Any amounts recovered in connection with any such
challenge or refund request shall be promptly paid to the Company.

2.13 Mitigation of Costs.

If any Investor requests compensation under Sections 2.11(a) or 2.11(b), or the Company is
required to pay any additional amount to any Investor or any Governmental Authority for the account
of any Investor pursuant to Section 2.12, then such Investor shall use reasonable efforts to
designate a different office for funding or holding its Preferred Stock and the Warrant hereunder
or to assign its rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Investor, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Sections 2.11(a), 2.11(b) or 2.12, as the case may
be, in the future, and (ii) in each case, would not subject such Investor to any unreimbursed cost
or expense and would not otherwise be disadvantageous to such Investor. The Company hereby agrees
to pay all reasonable costs and expenses incurred by any Investor in connection with any such
designation or assignment.

To induce the Company to enter into this Agreement and to induce the Company to issue and sell
the Preferred Stock and Warrant, each Investor as of the date of this Agreement (for purposes of
this Article IV-A, each “Investor”) represents and warrants to each the Company that the
statements contained in this Article IV-A are correct as of the date of this Agreement.

4A.1 Organization and Authority. Each Investor is duly organized, validly existing,
and in good standing under the laws of the jurisdiction of its formation. Each Investor has the
requisite power and authority to execute and deliver this Agreement and the Investment Documents to
which it is a party and to perform its obligations hereunder and thereunder. This Agreement and
the Investment Documents to which it is a party constitute the valid and legally binding
obligations of each Investor, enforceable in accordance with terms and conditions hereof
and thereof, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors’ rights generally, by general
equitable principles or by principles of good faith and fair dealing (regardless of whether
enforcement is sought in equity or at law).

 

39

 

Except as could not reasonably be expected to have a
material adverse effect on the ability of the Investors to fulfill their obligations under the
Investment Documents, assuming the accuracy of all representations and warranties of the Company
made herein, each Investor has given each notice to, made each filing with, and obtained each
authorization, consent, and approval of each government, governmental agency and third Person
required to be given, made or obtained by such Investor as of the date hereof to consummate the
transactions contemplated by this Agreement and the Investment Documents to which each Investor is
a party. The execution, delivery, and performance of this Agreement and the Investment Documents
to which each Investor is a party have been duly authorized by each Investor.

4A.2 Non-contravention. Assuming the accuracy of the representations and warranties
made by the Company in this Agreement (and the certificates and other documents contemplated
hereby), neither the execution and the delivery by the Investors of this Agreement, nor the
Investment Documents to which each Investor is a party, nor the consummation of the transactions
contemplated hereby or thereby, will (a) violate any constitution, statute, regulation, rule,
injunction, judgment, order, decree, ruling, charge or other restriction of any government,
governmental agency or court to which each Investor is subject or any provision of its
organizational documents, or (b) conflict with, result in a breach of, constitute a default under,
result in the acceleration of, or create in any party the right to accelerate, terminate, modify or
cancel, any agreement, contract, lease, license, instrument or other arrangement to which each
Investor is a party or by which it is bound or to which any of its assets is subject; except, where
such contraventions, violations, conflicts, breaches or defaults, individually or in the aggregate,
could not reasonably be expected to have a material adverse effect on the ability of the Investors
to fulfill their obligations under the Investment Documents.

solely for its own account as principal for investment purposes only and not with a view to or for
sale in connection with any distribution thereof within the meaning of the Securities Act, and (b)

evaluating and investing in companies such as the Company Parties and has substantial experience in
investing in and evaluating private placement transactions of securities in companies similar to

Preferred stock and Warrant and has the capacity to protect its own interests. Each Investor has
had an opportunity to discuss the Company Parties’ business, management, financial affairs and the
terms and conditions of the offering of the Preferred Stock and Warrant with management of the
Company Parties and has had an opportunity to review the Company Parties’ facilities.

4A.4 Restricted Securities. Each Investor acknowledges that, because the Preferred
Stock, Warrant and shares underlying the Warrant have not been registered under the Securities Act
of 1933 or any state securities laws, such securities must be held indefinitely unless subsequently
registered under the Securities Act of 1933 and applicable state securities law or an exemption
from registration or resale under such laws is available. Each Investor is familiar with
the provisions of Rule 144 promulgated under the Securities Act of 1933 and the resale limitation
imposed thereby and by the Securities Act.

 

40

otherwise resident in the states of New York, Illinois and North Carolina.

which a Small Business Concern (as defined in the SBIA) is prohibited from engaging in under 13
C.F.R §107.720(h). In the event any Person becomes such an Associate of any Investor prior to the
first anniversary of the date hereof, such Investor shall notify the Company of the identity of
such Associate.

investment company under the SBIA (an “SBIA Investor”), the Company will redeem the
Preferred Stock in full (at the Redemption Price) and purchase the Warrant at the purchase price
set forth therein, in immediately available funds, in the event that any Company Party changes the
nature of its business within one year after the Closing Date in a manner that would cause such
Company Party to be ineligible for financing under 13 C.F.R. §107.720 without the written approval
of the SBA to permit the SBIA Investor to retain such investment in the Company under 13 C.F.R.
§107.760(b)(1) (as amended from time to time).

accurate compliance reports at such times and in such form and containing such information as the
SBA may determine to be necessary to enable the SBA to ascertain whether the Company Parties have
complied or are complying with 13 C.F.R. Part 112 (“Part 112”). Upon the request of any
SBIA Investor, the Company Parties will submit to such SBIA Investor such information regarding the
Company Parties as may be reasonably necessary to enable such SBIA Investor to meet its reporting
requirements under Part 112. Each Company Party will permit the SBA to have access with advance
written notice and during normal business hours to such of its books, records, accounts and other
sources of information, and its facilities as may be pertinent to ascertain compliance with Part
112. Where any information required of the Company Parties is in the exclusive possession of any
other agency, institution or Person and such agency, institution or Person shall fail or refuse to
furnish this information, the Company Parties shall so certify in their report and shall set forth
what efforts they have made to obtain this information.

5.13 SEC Filings. In the event that the Company files a registration statement on Form 10,
or other form of registration statement, (the “Registration Statement”) with the Securities
and Exchange Commission (“SEC”) for the purpose of registering any of its Capital Stock
under the Exchange Act and, if applicable, the Securities Act (such Registration Statement and any
other reports filed with or furnished to the SEC, or required to be filed with or furnished to the
SEC, subsequent to the filing of such Registration Statement, if any, including any amendments
thereto, collectively the “Company SEC Documents”), each Company SEC Document, when filed
with or furnished to the SEC (or, in the case of any Registration Statement, when such Registration
Statement is declared effective by the SEC), will comply in all material respects with the
requirements of the Securities Act and the Exchange Act, as the case may be, and will comply, as
applicable, in all material respects with the then-applicable accounting standards. None of the
Company SEC Documents when filed will contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the statements therein,
in light of
the circumstances under which they were made, not misleading. Following the effectiveness of the
Registration Statement, to the extent required by the rules and regulations of the SEC, the Company
will file with and furnish to the SEC all reports required to be filed and furnished by an issuer
of equity securities registered under the Exchange Act.

8.2 Remedies: Redemption, etc.

Upon and at any time after the occurrence and during the continuance of any Event of
Noncompliance, each Investor may take any or all of the following actions at the same or different
times:

(a) (i) if such event is a Bankruptcy Event, the Company shall redeem immediately all of the
outstanding Preferred Stock and (ii) if such event is any other Event of Noncompliance, each
Investor, at its option, may require the Company to redeem all or any portion of the shares of
Preferred Stock held by such Investor (a “Put Right”) in accordance with the terms of the
Certificate of Incorporation and the Investment Documents. Each Investor may exercise its Put
Right by providing written notice of exercise of such Put Right to the Company identifying the
shares of Preferred Stock to be redeemed by the Company in accordance with the terms of the
Certificate of Incorporation and the Investment Documents. In the event of any redemption of the
Preferred Stock pursuant to this Section 8.2, the Company shall pay to each Investor an amount in
cash equal to the Redemption Price of the Preferred Stock. The Company also shall pay in cash to
such Investors at the time of such redemption all accrued and unpaid fees, charges
and other amounts owed by any Company Party to each such Investor under the Investment
Documents;

(b) at the option of the Required Investors, the Investors shall be entitled to receive
additional dividends on the Preferred Stock as provided in the Certificate of Incorporation; and

(c) exercise all rights and remedies available to it under this Agreement, the other
Investment Documents and applicable law.

8.3 Rescission of Put Right.

The provisions of this Article VIII are subject to the condition that, if any Investor has
given the Company notice that the Preferred Stock shall be redeemed by reason of the occurrence of
any Event of Noncompliance described in Section 8.2 other than a Bankruptcy Event, any Investor
may, by written instrument filed with the Company, rescind and annul such notice and the
consequences thereof; provided, however, that at the time such declaration is annulled and
rescinded: (i) no judgment or decree has been entered for the payment of any monies due pursuant
to the Preferred Stock or this Agreement; or (ii) the Preferred Stock had not previously been
redeemed by the Company; and (iii) each and every other Event of Noncompliance shall have been made
good, cured or waived, unless the same specifically has been waived in writing by such Investor;
provided, further, however, that no such rescission and annulment shall extend to or affect any
subsequent Event of Noncompliance or impair any right consequent thereto.

8.4 Remedies: Set-Off.

Upon and at any time after the occurrence and during the continuance of any Event of
Noncompliance, each Investor and each of its respective Affiliates is hereby authorized at any time
and from time to time, to the fullest extent permitted by applicable law, to set off and apply any
and all amounts at any time held and other obligations (in whatever currency) at any time owing by
such Investor or any such Affiliate to or for the credit or the account of the Company against any
and all of the obligations of the Company now or hereafter existing under this Agreement or any
other Investment Document to such Investor. The rights of each Investor and its respective
Affiliates under this Section are in addition to other rights and remedies (including other rights
of setoff) that such Investor or its Affiliates may have. Each Investor agrees to notify the
Company and each other Investor promptly after any such setoff and application; provided
that the failure to give such notice shall not affect the validity of such setoff and application.

MISCELLANEOUS

9.1 Expenses; Indemnity; Damage Waiver.

(a) The Company shall pay (i) all reasonable out-of-pocket expenses incurred by the Investors
(including the reasonable fees, charges and disbursements of counsel), in connection with the

thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and
(ii) all reasonable out-of-pocket expenses incurred by any Investor (including the reasonable fees,
charges and disbursements of any counsel for any Investor), in connection with the enforcement or
protection of its rights upon and during the continuance of an Event of Noncompliance (A) in

Section, or (B) in connection with the Preferred Stock and the Warrant purchased hereunder,
including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Preferred Stock and the Warrant.

(b) The Company shall indemnify each Investor, and each Related Party of any of the foregoing
Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee
harmless from, any and all losses, claims, damages, liabilities and related expenses (including the
reasonable fees, charges and disbursements of any counsel for any Indemnitee), incurred by any
Indemnitee in connection with a third-party claim or asserted against any Indemnitee by any third
party or by the Company or any other Company Party arising out of, in connection with, or as a
result of (i) the execution or delivery of this Agreement, any other Investment Document or any
agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of
their respective obligations hereunder or thereunder or the consummation of the transactions
contemplated hereby or thereby, (ii) any Preferred Stock or the Warrant or the use or proposed use
of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Substances
on or from any property owned or operated by any Company Party, or any Environmental Claim related
in any way to any Company Party, or (iv) any actual or prospective claim, litigation, investigation
or proceeding relating to any of the foregoing, whether based on contract, tort or any other
theory, whether brought by a third party or by the Company or any other Company Party, and
regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses (x) are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such
Indemnitee or (y) result from a claim brought by the Company or any other Company Party against an
Indemnitee for breach of such Indemnitee’s obligations hereunder or under any other Investment
Document, if the Company or such Company Party has obtained a final and nonappealable judgment in
its favor on such claim as determined by a court of competent jurisdiction. The Investors hereby
agree that the liability of the Company to all Investors pursuant to this Section 9.1(b) for
damages related to any diminution in value of the Warrants and the Warrant Shares (each, as defined
in the Warrant) resulting from an Event of Noncompliance shall be limited to a maximum aggregate
amount of
$2,000,000 and shall only be recoverable by such Investors in the event such damages are in
excess of $100,000 (in which case damages may be recovered back to dollar one).

 

61

 

(c) (i) If any third party shall promptly notify any Indemnitee with respect to any matter (a
“Third-Party Claim”) which may give rise to a claim for indemnification against any
indemnifying party under Section 9.1(b), then the Indemnitee shall notify the Company thereof in
writing (a “Notice of Third-Party Claim”); provided, however, that no delay
on the part of the Indemnitee in notifying any indemnifying party shall relieve the indemnifying
party from any obligation hereunder unless (and then solely to the extent) the indemnifying party
thereby is materially prejudiced. A Notice of Third-Party Claim shall state in reasonable detail
the nature of the Third-Party Claim.

(ii) Any indemnifying party will have the right to defend the Indemnitee against the
Third-Party Claim with counsel of its choice reasonably satisfactory to the Indemnitee so long as
(A) the indemnifying party provides written acknowledgement to the Indemnitee that the indemnifying
party will indemnify the Indemnitee in respect of the Third-Party Claim (except for any liabilities
under such Third-Party Claim determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful misconduct of such
Indemnitee) and provides notice to the Indemnitee that the indemnifying party intends to undertake
such defense and provides the Indemnitee with evidence reasonably acceptable to the Indemnitee that
the indemnifying party will have the financial resources to defend against the Third-Party Claim
and fulfill its indemnification obligations hereunder, (B) the Third-Party Claim involves only
money damages and does not seek an injunction or other equitable relief and (C) the indemnifying
party conducts the defense of the Third-Party Claim actively and diligently.

(iii) So long as the indemnifying party is conducting the defense of the Third-Party Claim in
accordance with this Section 9.1(c), (A) the Indemnitee may retain separate co-counsel at its sole
cost and expense and participate in the defense of the Third-Party Claim, (B) the Indemnitee will
not consent to the entry of any judgment or enter into any settlement with respect to the
Third-Party Claim without the prior written consent of the indemnifying party (not to be withheld
unreasonably), and (C) the indemnifying party will not consent to the entry of any judgment or
enter into any settlement with respect to the Third-Party Claim without the prior written consent
of the Indemnitee (not to be withheld unreasonably), provided that if the Indemnitee fails
to provide such consent within 30 days following a written request from the indemnifying party to
the Indemnitee in accordance with the notice provisions hereof and such settlement involves a full
release with no finding or indication of wrong doing by the Indemnitee or admission of liability by
the Indemnitee and involves only money damages and does not seek an injunction or other equitable
relief, the indemnification provided to the Indemnitee shall be limited to the amount of such
settlement.

(iv) In the event any of the conditions in Section 9.1(c)(ii) is or becomes unsatisfied,
however, (A) the Indemnitee may defend against, and consent to the entry of any judgment or enter
into any settlement with respect to, the Third-Party Claim in any manner it may deem reasonably
appropriate (and the Indemnitee need not obtain any consent from, any indemnifying party in
connection therewith), (B) the indemnifying party will reimburse the Indemnitee promptly and
periodically for the costs of defending against the Third-Party Claim (including
reasonable attorneys’ fees and expenses), and (C) the indemnifying party will remain
responsible for any amounts required to be indemnified hereunder the Indemnitee may suffer
resulting from, arising out of or relating to the Third-Party Claim to the fullest extent provided
in this Section 9.1.

 

62

 

(d) To the fullest extent permitted by applicable law, no party to this Agreement shall
assert, and each such party hereby waives, any direct claim against another party to this Agreement
(including without limitation, with respect to any indemnification obligation hereunder) on any
theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct
or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other
Investment Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Preferred Stock or the Warrant or the use of the proceeds
thereof, in each case other than a claim for diminution of value of the Warrants and Warrant Shares
(each, as defined in the Warrant); provided, however, that the limitations in this
sentence shall not in any way limit any rights of indemnification of an Indemnitee under Sections
9.1(a), 9.1(b) or 9.1(c). No Indemnitee referred to in Section 9.1(b) shall be liable for any
damages arising from the use by unintended recipients of any information or other materials
distributed by it through telecommunications, electronic or other information transmission systems
in connection with this Agreement or the other Investment Documents or the transactions
contemplated hereby or thereby.

(e) All amounts due under this Section shall be payable by the Company upon demand therefor
(except that the Investors shall not have the right to receive advances or payments of
out-of-pockets costs and expenses incurred in connection with a claim by the Investors for
diminution in value of the Warrants and Warrant Shares (each, as defined in the Warrant) prior to
resolution of such claim).

9.2 Governing Law; Submission to Jurisdiction; Waiver of Venue; Service of Process.

(a) This Agreement and the other Investment Documents shall (except as may be expressly
otherwise provided in any Investment Document) be governed by, and construed in accordance with,

parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action
or proceeding may be heard and determined in such state court or, to the fullest extent permitted

in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any
other Investment Document shall affect any right that any
Investor may otherwise have to bring any action or proceeding relating to this Agreement or
any other Investment Document against the Company or any other Company Party or its properties in
the courts of any jurisdiction.

 

63

 

(c) The Company irrevocably and unconditionally waives, to the fullest extent permitted by
applicable law, any objection that it may now or hereafter have to the laying of venue of any
action or proceeding arising out of or relating to this Agreement or any other Investment Document
in any court referred to in Section 9.2(b). Each of the parties hereto hereby irrevocably waives,
to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

(d) Each party hereto irrevocably consents to service of process in the manner provided for
notices in Section 9.4. Nothing in this Agreement will affect the right of any party hereto to

ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER
INVESTMENT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Neither the Company not any other Company Party shall assign any of its rights, or any of its
obligations, under this Agreement or any other Investment Document without first obtaining the
written consent of the Required Investors. This Agreement, each other Investment Document, the

Investor without obtaining the Consent of any Person; provided, however, that,
other than upon and during the continuance of any Event of Noncompliance, (i) with respect to

65

 

9.7 No Waiver.

The rights and remedies of the Investors expressly set forth in this Agreement and the other
Investment Documents are cumulative and in addition to, and not exclusive of, all other rights and
remedies available at law, in equity or otherwise. No failure or delay on the part of any Investor
in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single
or partial exercise of any such right, power or privilege preclude other or further exercise
thereof or the exercise of any other right, power or privilege or be construed to be a waiver of
any Event of Noncompliance. No course of dealing between any Company Party or the Investors or
their agents or employees shall be effective to amend, modify or discharge any provision of this
Agreement or any other Investment Document or to constitute a waiver of any Event of Noncompliance.
No notice to or demand upon any Company Party in any case shall entitle any Company Party to any
other or further notice or demand in similar or other circumstances or constitute a waiver of the
right of any Investor to exercise any right or remedy or take any other or further action in any
circumstances without notice or demand.

9.8 Survival.

All representations, warranties and agreements made by or on behalf of the Company or any
other Company Party in this Agreement and in the other Investment Documents shall survive from and

contrary, the provisions of this Agreement and the other Investment Documents relating to
indemnification or payment of costs and expenses, including, without limitation, the provisions of
Sections 2.11, 2.12 and 9.1, shall survive the redemption of the Preferred Stock, the exercise of
the Warrant and any termination of this Agreement or any of the other Investment Documents.

9.9 Severability.

To the extent any provision of this Agreement is prohibited by or invalid under the applicable
law of any jurisdiction, such provision shall be ineffective only to the extent of such prohibition
or invalidity and only in such jurisdiction, without prohibiting or invalidating such provision in
any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction.

9.10 Construction.

The headings of the various articles, sections and subsections of this Agreement and the table
of contents have been inserted for convenience only and shall not in any way affect the meaning or
construction of any of the provisions hereof. Except as otherwise expressly provided herein and in
the other Investment Documents, in the event of any inconsistency or conflict between any provision
of this Agreement and any provision of any of the other Investment Documents, the provision of this
Agreement shall control.

9.11 Confidentiality.

In handling any confidential information of any Company Party, each Investor shall exercise
the same degree of care that it exercises with respect to its own proprietary information of the
same types to maintain the confidentiality of any non-public information thereby received or
received pursuant to this Agreement, except that the foregoing shall not be construed to prevent
any Investor from:

(a) making any disclosure of any information (A) if required to do so by any Requirement of
Law, (B) to any Governmental Authority having or claiming authority to regulate or oversee any
aspect of such Person’s business or that of the corporate parent or affiliates of such Person in

part, by the Preferred Stock or the Warrant (as used in this Section 9.11, a
“Securitization”) that agrees that its access to such confidential information is solely
for purposes of evaluating an investment in such Securitization and who agrees to treat such
information as confidential;

(g) making disclosures to a Person that is a trustee, collateral manager, servicer, backup

information. Notwithstanding any other express or implied agreement, arrangement or understanding
to the contrary, the parties hereto hereby agree that each of the parties hereto (and each of their
respective employees, representatives, or agents) are permitted to disclose to any and all Persons,
without limitation of any kind, the tax treatment and tax aspects of the transactions contemplated
by the Investment Documents, and all materials of any kind (including opinions or other tax
analyses) that are provided to such parties related to such tax treatment and tax aspects.

9.12 Counterparts; Integration; Effectiveness.

This Agreement may be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement and the other Investment Documents constitute
the entire contract among the parties relating to the subject matter hereof and supersede any and
all previous agreements and understandings, oral or written, relating to the subject matter hereof
(except for the Fee Letter). Except as provided in Section 3.1, this Agreement shall become
effective when it shall have been executed by the Investors and when the Investors shall have
received counterparts hereof that, when taken together, bear the signatures of each of the other

9.15 Subordination; Payment Restrictions.

(a) Any payment to any Investor under or on account of the obligations under the Investment
Documents (the “Subordinated Obligations”) is hereby expressly subordinated to the extent
and in the manner set forth in this Section 9.15 to the payment in full of the indebtedness (the
“Senior Indebtedness”) of the Company to Wells Fargo Bank, National Association (“Wells
Fargo”), under a Credit and Security Agreement dated as of October 24, 2006, as amended, by and
between the Company, Wells Fargo, as agent, and the lenders thereunder from time to time (such
lenders collectively, the “Senior Lenders”) as the same may hereafter be further amended,
supplemented or restated from time to time (the “Credit Agreement”). The payment rights of
each Investor shall continue to be subordinated to the Senior Indebtedness on the terms set forth
in this Agreement even if the Senior Indebtedness is deemed unsecured, under-secured, subordinated,
avoided or disallowed under the United States Bankruptcy Code or other applicable law.

(b) Until all of the Senior Indebtedness has been paid in full, no Investor shall, without the
prior written consent of the Senior Lenders holding a majority of the Senior Indebtedness, receive
or accept any payment from the Company under or on account of the obligations under the Investment
Documents, or exercise any right of or permit any setoff with respect to the Subordinated
Obligations, except that the Investors may accept (i) scheduled quarterly dividends (but not
prepayments) to be paid under the Certificate of Designations, Preferences and Rights of Series B
Preferred Stock of Pure Earth, Inc. of even date herewith, except upon the occurrence and during
the continuance of an event of default under the Credit Agreement either immediately before or
following any such payment and (ii) any payment made out of funds held in any New Equity Account
(as defined in the Credit Agreement as in effect on the date hereof).

(c) If any Investor receives any payment that the Investor is not entitled to receive under
the provisions of this Agreement, the Investor will hold the amount so received in trust for the
Senior Lenders and will forthwith turn over such payment to the Senior Lenders in the form received
(except for the endorsement of the Investor where necessary) for application to the Senior
Indebtedness (whether or not due), in such manner of application as the Senior Lenders may deem
appropriate. If an Investor exercises any right of setoff which the Investor is not permitted to
exercise under the provisions of this Agreement, the Investor will promptly pay over to the Senior
Lenders, in immediately available funds, an amount equal to the amount of the claims or obligations
offset.

(d) Each Senior Lender shall be a third party beneficiary entitled to enforce the provisions
of this Section 9.15.

(e) Upon the Company’s entry into any other secured credit facility in replacement of or in
addition to the Senior Indebtedness, whether with the Senior Lenders or one or more substitute
lenders, each Investor agrees to enter into documentation with the Company and such lenders
providing the lenders with substantially the same subordination and other rights as are held by the
Senior Lenders pursuant to this Section 9.15.
