ARTICLE 2 —  LOAN COMMITMENT

2.1 Term Loan.

     (a) Loan Commitment. Subject to the terms and conditions of this Agreement and the
other Loan Documents, and in reliance upon the representations and warranties of Borrower set forth
herein and in the other Loan Documents, and agrees to make a Term Loan to Borrower as follows: On
the Closing Date, Lender will lend to Borrower the principal amount set forth opposite such
Lender’s name on Schedule A affixed hereto, as amended from time to time.

     Amounts borrowed and repaid under this Section 2.1 may not be reborrowed.

     (b) Use of Proceeds. Proceeds of the borrowing funded on the Closing Date and each
additional borrowing shall be used for general corporate purposes.

     (c) Maturity; Optional Prepayment. The outstanding principal balance of the Term Loan
and any unpaid interest shall be due and payable in full on the Maturity Date, unless the same
shall become due sooner pursuant to the terms of this Agreement. Commencing June 1, 2008 (but not
before such date) Borrower shall have the right to prepay all or any part of the Term Loan, upon
not less than thirty (30) days’ prior written notice to Lender, without premium or penalty.

     (d) Interest. (i) Except as otherwise provided below, the principal amount of the
Term Loan outstanding shall bear interest at ten percent (10%) per annum, calculated using a year
of 365 or 366 days (as applicable) and actual days elapsed. During any period when an Event of
Default has occurred and is continuing, the Loan shall bear interest at the Default Rate. Prior to
maturity, interest shall be payable quarterly in arrears on each March 31, June 30, September 30
and December 31, with the first such payment due on June 30, 2007. After maturity, whether at
scheduled maturity or pursuant to acceleration, interest shall be payable on demand.

          (ii) The Loan is a business loan. Notwithstanding any provision to the contrary contained in
this Agreement or the Note or any other Loan Document, Borrower shall not be required to pay, nor
shall Lender be permitted to collect, any amount of interest in excess of the maximum amount of
interest permitted by law (“Excess Interest”). If any Excess Interest is provided for, or
determined by a court of competent jurisdiction to have been provided for, in this Agreement, the
Note or any other Loan Document, then in such event:

               (A) the provisions of this Section 2.1(d)(ii) shall govern and control;

               (B) Borrower shall not be obligated to pay any Excess Interest;

               (C) any Excess Interest that a Lender may have received hereunder shall be, at Lender’s
option, (x) applied as a credit against the outstanding principal balance of the Term Loan or
accrued and unpaid interest (not to exceed the maximum amount permitted by law), (y) refunded to
Borrower, or (z) any combination of the foregoing;

Page 5 of 17

 

               (D) the interest rate(s) provided for herein shall be automatically reduced to the maximum
lawful rate allowed from time to time under applicable law (the “Maximum Rate”), and this
Agreement, the Note and the other Loan Documents shall be deemed to have been and shall be reformed
and modified to reflect such reduction; and

               (E) Borrower shall not have any action against Lender for any damages arising out of the
payment or collection of any Excess Interest.

     (e) Subordination. Each Lender agrees to subordinate the Borrower’s Obligations in
the event that Borrower is able to arrange to have a commercial lender provide financing to
Borrower for similar purposes and such commercial lender requires that the Term Loan be
subordinated. Such subordination shall be substantially on the terms and conditions set forth in
the Subordination Terms.

2.2 Term Note; Lender’s Loan Records. The Term Loan shall be evidenced by the
Term Note. At the time of the initial disbursement of the Term Loan, and at each time a repayment
made in whole or in part thereon, a notation thereof shall be made on the books and records of
Lender. All amounts recorded shall be, absent demonstrable error, conclusive and binding evidence
of (i) the principal amount of the Term Loan advanced hereunder, (ii) any accrued and unpaid
interest owing on the Term Loan and (iii) all amounts repaid on the Term Loan. The failure to
record any such amount or any error in recording such amounts shall not, however, limit or
otherwise affect the obligations of Borrower to repay the principal amount of the Term Loan,
together with all interest accruing thereon.

2.3 Payments. If any payment to be made by Borrower hereunder shall become due on a
day other than a Business Day, such payment shall be made on the next succeeding Business Day and
such extension of time shall be included in computing any interest in respect of such payment. All
payments made by Borrower hereunder or under any of the Loan Documents shall be made without
setoff, counterclaim, or other defense. To the extent permitted by applicable law, all payments
hereunder or under any of the Loan Documents (including any payment of principal, interest, or
fees) to, or for the benefit, of any Person shall be made by Borrower free and clear of, and
without deduction or withholding for, or account of, any taxes now or hereinafter imposed by any
taxing authority.

ARTICLE 8 —  MISCELLANEOUS.

8.1 Entire Agreement. This Agreement and the other Loan Documents constitute the
entire agreement
between the parties with respect to the subject matter hereof and thereof; and are the final
expression of the intentions of Borrower and each Lender. No promises, either expressed or
implied, exist between Borrower and any Lender, unless contained herein or therein. This
Agreement, together with the other Loan Documents, supersedes all negotiations, representations,
warranties, commitments, term sheets, discussions, negotiations, offers or contracts (of any kind
or nature, whether oral or written) prior to or contemporaneous with the execution hereof with
respect to any matter, directly or indirectly related to the terms of this Agreement and the other
Loan Documents. This Agreement and the other Loan Documents are the result of negotiations between
each Lender and Borrower, and have been reviewed (or have had the opportunity to be reviewed) by
counsel to all such parties, and are the products of all parties. Accordingly, this Agreement and
the other Loan Documents shall not be construed more strictly against any party merely because of
such party’s involvement in their preparation.

8.2 Amendments; Waivers; Lender Consent Terms. No amendment, modification or waiver
of, or consent with respect to, any provision of this Agreement or the other Loan Documents shall
in any event be effective unless the same shall be in writing and acknowledged and consented to by
Lenders and then any such amendment, modification, waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given. Any approval, consent or
satisfaction with respect to, or any amendment, modification or waiver of, any provision of this
Agreement or any other Loan Document by Lenders as a group or any individual Lender shall require
the prior written consent of the holders of a majority of the then-outstanding principal amount of
the Term Notes.

8.3 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, SHALL BE
BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED STATES
DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED THAT NOTHING IN THIS AGREEMENT SHALL
BE DEEMED OR OPERATE TO PRECLUDE LENDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY
OTHER JURISDICTION. BORROWER HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE
COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT
OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. BORROWER FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS. BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM
THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

8.4 WAIVER OF JURY TRIAL. EACH LENDER AND BORROWER, AFTER CONSULTING OR HAVING HAD
THE OPPORTUNITY TO CONSULT WITH COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE
IRREVOCABLY, ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY
RIGHTS UNDER THIS AGREEMENT, ANY NOTE, ANY OTHER LOAN DOCUMENT, ANY OF THE OTHER OBLIGATIONS, THE
COLLATERAL, OR ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH MAY IN THE
FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR ARISING FROM ANY LENDING

Page 12 of 17

 

RELATIONSHIP
EXISTING IN CONNECTION WITH ANY OF THE FOREGOING, OR ANY COURSE OF CONDUCT OR COURSE OF DEALING IN
WHICH LENDER AND BORROWER ARE
ADVERSE PARTIES, AND EACH AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT
AND NOT BEFORE A JURY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR LENDER GRANTING ANY FINANCIAL
ACCOMMODATION TO BORROWER.

8.5 Assignability. A Lender may at any time assign such Lender’s rights in this
Agreement, the other Loan Documents, the Obligations, or any part thereof to any Person which is
not a competitor of the Borrower or of any of Subsidiary of the Guarantor, and which expressly
agrees in writing that it will subordinate the interests which it is acquiring to the extent
provided with respect to such Lender in Section 2.1(e) hereof. In addition, a Lender may at any
time sell one or more participations in the Loans. Borrower may not sell or assign this Agreement,
or any other agreement with Lender or any portion thereof, either voluntarily or by operation of
law, without the prior written consent of the Lenders. This Agreement shall be binding upon each
Lender and Borrower and their respective legal representatives and successors. All references
herein to Borrower shall be deemed to include any successors, whether immediate or remote.

8.6 Confirmations. Borrower and Lender agree from time to time, upon written request
received by either from the other, to confirm to the other in writing the aggregate unpaid
principal amount of the Loans then outstanding.

8.7 Confidentiality. Each Lender, severally and jointly, agrees to use commercially
reasonable efforts (equivalent to the efforts such Lender applies to maintain the confidentiality
of its own confidential information) to maintain as confidential all information provided to it by
Borrower and designated as confidential, except that Lender may disclose such information (a) to
Persons employed or engaged by Lender in evaluating, approving, structuring or administering the
Loans; (b) to any assignee or participant or potential assignee or participant that has agreed to
comply with the covenant contained in this Section 8.7 (and any such assignee or participant or
potential assignee or participant may disclose such information to Persons employed or engaged by
them as described in clause (a) above); (c) as required or requested by any federal or state
regulatory authority or examiner, or any insurance industry association, or as reasonably believed
by Lender to be compelled by any court decree, subpoena or legal or administrative order or
process; (d) as, is required by law; (e) in connection with the exercise of any right or remedy
under the Loan Documents or in connection with any litigation to which Lender is a party; (f) to
any nationally recognized rating agency that requires access to information about Lender’s
investment portfolio in connection with ratings issued with respect to Lender; or (g) that ceases
to be confidential through no fault of Lender.

and accepted in and shall be deemed to be contracts made under and governed by the internal laws of
the State of Illinois applicable to contracts made and to be performed entirely within such state,
without regard to conflict of laws principles.

8.10 Enforceability. Wherever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision
of this Agreement shall be prohibited by, unenforceable or invalid under any jurisdiction, such
provision shall as to such jurisdiction, be severable and be ineffective to the extent of such
prohibition or invalidity, without invalidating the remaining provisions of this Agreement or
affecting the validity or enforceability of such provision in any other jurisdiction.

8.11 Extensions of Lender’s Commitment. This Agreement shall secure and govern the
terms of (i) any extensions or renewals of Lender’s commitment hereunder, and (ii) any replacement
note executed by Borrower and accepted by Lender in its sole and absolute discretion in
substitution for any Note.

Lender under this Agreement and in the performance and observance by Borrower of each covenant,
agreement, provision and term of this Agreement.

8.13 Counterparts; Facsimile Signatures. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts and each such counterpart
shall be deemed to be an original, but all such counterparts shall together constitute but one and
the same Agreement. Receipt of an executed signature page to this Agreement by facsimile or other
electronic transmission shall constitute effective delivery thereof. Electronic records of
executed Loan Documents maintained by Lender shall deemed to be originals thereof.

8.15 Costs, Fees and Expenses. Borrower shall pay or reimburse each Lender for all
reasonable costs,
fees and expenses incurred by such Lender or for which Lender becomes obligated in connection with
the negotiation, preparation, consummation, collection of the Obligations or enforcement of this
Agreement, the other Loan Documents and all other documents provided for herein or delivered or to
be delivered hereunder or in connection herewith (including any amendment, supplement or waiver to
any Loan Document), or during any workout, restructuring or negotiations in respect thereof,
including reasonable consultants’ fees and attorneys’ fees and time charges of counsel to Lender,
plus costs and expenses of such attorneys or of Lender; search fees, costs and expenses; and all
taxes payable in connection with this Agreement or the other Loan Documents, whether or not the
transaction contemplated hereby shall be consummated. In furtherance of the foregoing, Borrower
shall pay any and all stamp and other taxes, UCC search fees, filing fees and other costs and
expenses in connection with the execution and delivery of this Agreement, any Note and the other
Loan Documents to be delivered hereunder, and agrees to save and hold each Lender harmless from and
against any and all liabilities with respect to or resulting from any delay in paying or omission
to pay such costs and expenses. That portion of the Obligations consisting of costs, expenses or
advances to be reimbursed by Borrower to any Lender pursuant to this Agreement or the other Loan
Documents shall be payable by Borrower to such Lender on demand.

8.16 Indemnification. Borrower agrees to defend (with counsel reasonably satisfactory
to the Lenders), protect, indemnify, exonerate and hold harmless each Indemnified Party from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, claims, costs, expenses and distributions of any kind or nature (including the disbursements
and the reasonable fees of counsel for each Indemnified Party thereto), which may be imposed on,
incurred by, or asserted against, any Indemnified Party in any manner relating to or arising out of
this Agreement or any of the Loan Documents, or any act, event or transaction related or attendant
thereto, the preparation, execution and delivery of this Agreement and the Loan Documents,
including the making or issuance and management of the Loans, the use or intended use of the
proceeds of the Loans, the enforcement of Lender’s rights and remedies under this Agreement, the
Loan Documents, any Note, any other instruments and documents delivered hereunder, or under any
other agreement between Borrower and Lender; provided, however, that Borrower shall not have any
obligations hereunder to any Indemnified Party with respect to matters determined by a court of
competent jurisdiction by final and nonappealable judgment to have been caused by or resulting from
the willful misconduct or negligence of such Indemnified Party or by the Lender’s breach of its
obligations under the Loan Documents. To the extent that the undertaking to indemnify set forth in
the preceding sentence may be unenforceable because it violates any law or public policy, Borrower
shall satisfy such undertaking to the maximum extent permitted by applicable law. Any liability,
obligation, loss, damage, penalty, cost or expense covered by this indemnity shall be paid to each
Indemnified Party on demand, and failing prompt payment, together with interest thereon at the
Default Rate from the date of demand until paid by Borrower, shall be added to the Obligations of
Borrower and be secured by the Collateral. The provisions of this Section shall survive the
satisfaction and payment of the other Obligations and the termination of this Agreement.

Page 15 of 17

 

8.17 Revival and Reinstatement of Obligations. If the incurrence or payment of the
Obligations by any Obligor or the transfer to any Lender of any property should for any reason
subsequently be declared to be void or voidable under any state or federal law relating to
creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent conveyances,
preferences, or other voidable or recoverable payments of money or transfers of property
(collectively, a “Voidable Transfer”), and if such Lender is required to repay or restore, in whole
or in part, any such Voidable Transfer, or elects to do so upon the reasonable advice of its
counsel, then, as to any such Voidable Transfer, or the amount thereof that such Lender is required
or elects to repay or restore, and as to all reasonable costs, expenses, and attorneys fees of such
Lender, the Obligations shall automatically shall be revived, reinstated, and restored and shall
exist as though such Voidable Transfer had never been made.

8.18 Customer Identification — USA Patriot Act Notice. Each Lender hereby notifies
Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56,
signed into law October 26, 2001) (the “Act”), and such Lender’s policies and practices, such
Lender is required to obtain, verify and record certain information and documentation that
identifies Borrower, which information includes the name and address of Borrower and such other
information that will allow Lender to identify Borrower in accordance with the Act.

     4. Permitted Payments of Subordinated Debt. Notwithstanding anything contained herein
to the contrary, the Subordinated Lenders may receive, and Borrower may pay regularly scheduled
payments of interest on the Subordinated Loan as and when the same become due in accordance with
the provisions the Junior Loan Agreement as in effect on the date of this agreement,
provided that at the time of making such payment, no Senior Event of Default exists or
would be caused thereby.

     5. No Payments in Violation of this Agreement. Borrower shall not make any payment,
and the Subordinated Lenders shall not receive or accept any payment, with respect to the
Subordinated Debt in violation of this Agreement. In the event that any Subordinated Lender
receives any payment from Borrower in violation of this Agreement, whether such payment is in cash,
by setoff or otherwise, such Subordinated Lender shall be liable and accountable therefore to the
Senior Lenders in the manner hereinafter set forth. The Subordinated Lender shall be deemed to
have received such payment in trust for the use and benefit of the Senior Lenders. The
Subordinated Lender shall not commingle the same with any other funds and shall pay over and
deliver such payment immediately to the Senior Lenders.

     6. Continuing Subordination. The subordination provided by this Agreement shall
survive and remain in full force and effect in the event of any administration of the property
and/or affairs of Borrower arising from any assignment for the benefit of creditors, or other
Insolvency Event. This is a continuing subordination and shall continue in full force and effect,
and Senior Lenders may make advancements of credit to Borrower in reliance upon this Agreement at
any time any Senior Obligations remain unpaid. Subordinated Lenders agree that the Senior Lenders,
at any time and from time to time, may enter into such agreement with Borrower as the Senior
Lenders and Borrower may deem proper
affecting any property which secures the Senior Obligations (the “Collateral”) and may
sell, surrender or

 

 

otherwise deal with any of the Collateral without notice to the Subordinated
Lenders (except as required by the Uniform Commercial Code or any other applicable law) and without
in any way impairing or affecting the subordination provided in this Agreement. The obligations of
the Subordinated Lenders hereunder shall not be affected or impaired by any compromise, release,
renewal, extension, forbearance, indulgence, alteration, change in, modification of, grant of
participation in, or other disposition of any of the Senior Loan Documents or any other documents
or instruments executed by Borrower in favor of the Senior Lenders, any release of any guarantor of
the obligations of Borrower to the Senior Lenders or any other person or the failure of the Senior
Lenders to pursue remedies against any one or more of the guarantors or any other person, failure
to collect any indebtedness owed by Borrower to the Senior Lenders when due, or any delay or
omission by the Senior Lenders in the exercise of any right or remedy against Borrower or any
guarantor of any of the Senior Obligations.

     7. No Assignment, Modification or Management. So long as any Senior Obligations are
outstanding, the Subordinated Lenders agree not to assign, transfer or pledge any rights, claims or
interests of any kind in or to any Subordinated Debt or to amend or modify any of the terms and
provisions of any of the Junior Loan Documents, without first obtaining the prior written consent
of the Senior Lenders. Any such transfer, assignment or pledge without such prior written consent
shall be void. Any such transfer, assignment or pledge to which the Senior Lenders consent shall
be made expressly subject to the terms and conditions hereof.

$0.0001 per share (“Common Stock”) continues to be publicly traded and the Company
continues to comply with the reporting requirements of the Securities Exchange Act, the Company

Common stock at a conversion price of $1.00 per share (the “Conversion Price”). Any such
written notice shall be delivered at the address for the Company applicable under the Loan
Agreement and shall state the amount of principal and interest being converted and the applicable
conversion date (which shall not be earlier than the date upon which such notice is given to the
Company).

     (b) The outstanding principal balance of the Loan and all accrued unpaid interest thereon
shall automatically be converted into shares of Common Stock at the Conversion Price, without

or upon automatic conversion under clause (b) above, such Lenders shall be deemed for all corporate
purposes to have become the holder of record of the shares of Common Stock with respect to which
such conversion occurs (which, for purposes of clause (a) shall be the date specified in the notice
given with respect to a conversion under clause (a)), irrespective of the date of delivery of
certificates evidencing such shares.

THIS CERTIFICATE (THE “SHARES”) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED FOR SALE, SOLD,
TRANSFERRED OR ASSIGNED UNLESS (A) SUBSEQUENTLY REGISTERED PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS
OR (B) THE HOLDER HEREOF SHALL HAVE DELIVERED TO THE COMPANY A WRITTEN OPINION OF
COUNSEL, IN FORM, SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE COMPANY, TO THE
EFFECT THAT THE SHARES TO BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED ARE
BEING OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED PURSUANT TO AN EXEMPTION FROM
SUCH REGISTRATION.

     5. Registration Rights. The Company shall:

     (a) Demand Registration. In the event the Company shall receive from a Lender a
written request that the Company effect any registration, qualification or compliance under the
Securities Act with respect to at least thirty-three percent (33%) of the aggregate Warrant Shares
and the shares of Common Shares which have been issued to such Lender pursuant to Section 2
or Section 3 of this Agreement (“Agreement Shares,” and, collectively with the
Warrant Shares, the “Registrable Securities”) for resale by the Lenders from time to time
through the over-the-counter market or in privately-negotiated transactions or otherwise, the
Company, as soon as practicable, shall (i) use its best efforts to prepare and file with the SEC a
registration statement (the “Registration Statement”), and (ii) provide to each Lender a
draft of the Registration Statement for review and comment within thirty (30) days after receipt of
the initial Lender’s request for such registration. Notwithstanding the foregoing, the Company
shall have no obligations pursuant to this Section 5(a) unless the number of shares to be
registered for the Lenders pursuant to this Section 5(a) shall be at least 1,000,000 in the
aggregate, which amount shall be subject to adjustment for stock splits and other similar pro rata
combinations of the Company’s common stock.

     (b) Subject to the provisions of clause (g) below, and to receipt of all necessary information
from the Lenders, the Company uses reasonable efforts to cause the Registration Statement to be
declared effective as promptly as practicable after filing thereof, and in any event within ninety
(90) days after filing thereof.

     (c) Use reasonable efforts to keep the Registration Statement continuously effective under the
Securities Act until the date which is the earlier of the date (i) when all Registrable Securities
have been sold, or (ii) the date that is the eighteenth (18th) month anniversary of the date the
Registration Statement shall have been declared effective.

     (d) File any documents required of the Company for customary “blue sky” clearance in Illinois.

 

 

     (e) File with the SEC in a timely manner the reports and other documents required to be filed by
it under the Securities Act and the Securities Exchange Act (or, if the Company is not required to
file such reports, it will, upon the request of any Lender, make publicly available other
information so long as necessary to permit sales by Lenders under Rule 144), all to the extent
required to enable Lenders to sell the Registrable Securities from time to time without
registration under the Securities Act within the limitations provided by Rule 144;
provided, however, that nothing in this Agreement shall require the Company to file reports
under the Securities Act or the Securities Exchange Act, to register any of its securities under
the Securities Exchange Act, or to make publicly available any information concerning the Company
at any time when it is not required by law or by any other agreement by which it is bound to do any
of the foregoing.

     (f) All expenses relating to the registration and offering of the Registrable Securities
pursuant to this Section 5 shall be borne by the Company, except that Lenders shall bear
underwriting and selling commissions attributable to the Registrable Securities being registered
and any transfer taxes on shares being sold by Lenders.

     (g) In addition to and without limitation of any other covenant of Lenders contained in this
Agreement, each Lender who desires to have its Registrable Securities registered pursuant to this
Section 5 shall:

     (i) Furnish to the Company, upon the Company’s request, all information regarding
Lenders and the intended distribution of the Registrable Securities for the purpose of
preparing such Registration Statement, to the extent that such information is required to
comply with applicable legal requirements; and

     (ii) Upon the Company’s request, notify the Company of the number of Registrable
Securities that have been sold and remain to be sold pursuant to any the Registration
Statement; and

     (iii) promptly notify the Company when all registered Registrable Securities have been
sold.

     (h) Lender agrees not to effect any disposition of any Registrable Securities or the right to
purchase any Registrable Securities that would constitute an offer or sale within the meaning of
the Securities Act except as contemplated in this Section 5 or pursuant to an exemption
from registration under the Securities Act.

     (i) The Company will promptly notify Lender at any time when a prospectus relating to
Registrable Securities is required to be delivered under the Securities Act of the happening of any
event as a result of which the prospectus included in such Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make the statements therein not misleading or incomplete in
the light of the circumstances then existing.

     (j) The Company will furnish to Lender with respect to the Registrable Securities registered
under the Registration Statement (and to each underwriter, if any, of such Registrable Securities)
such number of copies of the Registration Statement and any amendment or supplement thereto and of
prospectuses and preliminary prospectuses in conformity with the requirements of the Securities Act
as Lender shall reasonably request.

 

 

     (k) The Company shall prepare and file with the SEC such amendments and supplements to such
Registration Statement and the prospectus used in connection therewith as may be necessary so that,
as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading or incomplete in the
light of the circumstances then existing; provided, however, the Company may,
subject to the last sentence of this clause (k), temporarily suspend the use of the prospectus
forming a part of such registration statement in the event that, and during such period as,

     (i) the Company is engaged in confidential negotiations or other confidential
business activities, disclosure of which would be required to be included or incorporated by
reference in such prospectus or registration statement, and

     (ii) the Board of Directors of the Company determines in good faith that such
disclosure would have a material adverse effect on any such confidential negotiations or
other confidential business activities or would be materially detrimental to the Company.

In such event, subject to the last sentence of this clause (k), the Company may suspend the use of
such prospectus until such time as an amendment to such Registration Statement has been filed by
the Company and declared effective by the SEC, or until such time as the Company has filed an
appropriate report with the SEC pursuant to the Securities Exchange Act. Anything herein to the
contrary notwithstanding, the Company does not have the right to suspend the use of such prospectus
or otherwise restrict Lender’s ability to sell or otherwise transfer the Registrable Securities for
a period of more than 90 days (which need not be consecutive days) in any twelve month period.

     (l) The Company will promptly inform Lender when any stop order by the SEC has been issued
with respect to the Registrable Securities and use its best efforts to promptly cause such stop
order to be withdrawn.

     (m) The Company will cause all Registrable Securities registered pursuant to such Registration
Statement to be listed on each securities exchange or market system on which the Company’s Common
Stock then is listed.

     (n) The Company will take such other actions as may be reasonably necessary to effect the
registration of the resale of the Registrable Securities in accordance with the terms of this
Agreement, to allow such Registrable Securities to trade in the same market system or exchange
where the Company’s Common Stock then trades, and to comply with all rules and regulations of the
SEC applicable thereto.

     (o) Indemnification and Contribution. For the purpose of this clause (o), the term
“Lender Party” shall include the Lender and its respective officers, directors, and any
Person which controls Lender, and the term “Registration Statement” shall include the
Registration Statement to be filed pursuant to this Section 5 and any final prospectus,
supplement or amendment included in or relating to such Registration Statement.

     The Company agrees to indemnify and hold harmless each Lender Party from and against any
losses, claims, damages or liabilities to which such Person may become subject (under the
Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon any untrue statement or alleged
untrue statement of a material fact contained in a Registration Statement or the omission or
alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not misleading or
arise out of

 

 

any failure by the Company to fulfill any undertaking included in a Registration
Statement and the Company will reimburse such Lender Party for any reasonable legal or other
expenses reasonably incurred in investigating, defending or preparing to defend any such action,
proceeding or claim as such expenses are incurred; provided, however, that the Company
shall not be liable in any such case to the extent that such loss, claim, damage or liability
arises out of, or is based upon, any such untrue statement or omission made in such Registration
Statement in reliance upon written information furnished to the Company by or on behalf of Lender
or any Lender Party expressly for use in preparation of the Registration Statement, or the failure
of such Lender Party to comply with the covenants and agreements of the Lender contained in this
Section 5 respecting sale of any Registrable Securities or any statement or omission in any
prospectus that is corrected or made not misleading in any subsequent prospectus that was delivered
to Lender or such Lender Party prior to the pertinent sale or sales by such Lender Party.

     Each Lender agrees, severally and jointly, to indemnify and hold harmless the Company (and
each person, if any, who controls the Company within the meaning of Section 15 of the Securities
Act, and each of its officers and directors who sign the Registration Statement) from and against
any losses, claims, damages or liabilities to which the Company (or any such officer, director or
controlling person) may become subject (under the Securities Act or otherwise), insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of,
or are based upon, any failure by such Lender or any respective Lender Party to comply with the
covenants and agreements of such Lender contained in Section 4 hereof respecting sale of
any Registrable Securities, or any untrue statement or alleged untrue statement of a material fact
contained (or incorporated by reference), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, in the Registration Statement on the effective date thereof if such untrue statement
was made in reliance upon and in conformity with written information furnished by or on behalf of
such Lender or any respective Lender Party for use in preparation of such Registration Statement.
Each Lender will reimburse, severally and not jointly, the Company (or such officer, director or
controlling person), as the case may be, for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or claim. In no event
shall the liability of any Lender hereunder be greater in amount than the dollar amount of the net
proceeds received by such Lender and the respective Lender Parties upon the sale of the Registrable
Securities giving rise to such indemnification obligation.

     Promptly after receipt by any indemnified person of a notice of a claim or the beginning of
any action in respect of which indemnity is to be sought against an indemnifying person pursuant to
this clause (o), such indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in
case any such action shall be brought against an indemnified person, such indemnifying person shall
be entitled to participate therein, and, to the extent it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the
indemnifying person to such indemnified person of its election to assume the defense thereof, such
indemnifying person shall not be liable to such indemnified person for any legal expenses
subsequently incurred by such indemnified person in connection with the defense thereof;
provided, however, that if there exists or shall exist a conflict of interest that would
make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to
represent both the indemnified person and such indemnifying person, the indemnified person shall be
entitled to retain its own counsel (in addition to local counsel) at the expense of such
indemnifying person; provided, further, that no indemnifying person shall be
responsible for the fees and expenses of more than one separate counsel for all indemnified parties
collectively without regard to the number of Lenders or Lender Parties. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its written
consent, but, if settled with such consent or if there be a final

 

 

judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party or parties in accordance with the
provisions of this clause (o).

     If the indemnification provided for in this clause (o) from the indemnifying person is
determined by a court of competent jurisdiction to be unavailable to an indemnified person
hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein,
then the indemnifying person, in lieu of indemnifying such indemnified person, shall contribute to
the amount paid or payable by such indemnified person as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the
indemnifying person and indemnified persons in connection with the actions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant equitable
considerations. The relative fault of such indemnifying person and indemnified persons shall be
determined by reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact or omission or alleged omission, has been
made by, or relates to information supplied by, such indemnifying person or indemnified persons,
and the parties’ relative intent, knowledge, access to information and opportunity to correct or
prevent such action. The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include, subject to the
limitations set forth in this clause (o), any reasonable legal or other fees or expenses reasonably
incurred by such party in connection with any investigation or proceeding. The parties hereto
agree that it would not be just and equitable if contribution pursuant to this clause (o) were
determined by pro rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this clause (o), no Lender shall be required to contribute any
amount in excess of the dollar amount of the gross proceeds received by such Lender and the
respective Lender Parties upon the sale of the Registrable Securities giving rise to such
contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

     (p) The conditions precedent imposed upon the transferability of the Registrable Securities by
this Section 5 shall cease and terminate as to any particular number of the Registrable
Securities when such Registrable Securities shall have been effectively registered under the
Securities Act and sold or otherwise disposed of in accordance with the intended method of
disposition set forth in the Registration Statement covering such Registrable Securities or at such
time as an opinion of counsel satisfactory to the Company shall have been rendered to the effect
that such conditions are not necessary in order to comply with the Securities Act.

     (q) So long as a registration statement is effective covering the resale of any Registrable
Securities, the Company will furnish to each Lender:

     (i) As soon as practicable after available (but in the case of the Company’s Annual
Report on Form 10-K, within 120 days after the end of each fiscal year of the Company), one
copy of (i) its Annual Report on Form 10-K or equivalent form (which shall contain financial
statements audited in accordance with generally accepted accounting principles by a firm of
certified public accountants), and (ii) a full copy of the Registration Statement covering
the Registrable Securities which are registered thereby (the foregoing, in each case,
excluding exhibits);

     (ii) Upon the reasonable request of any Lender, any exhibits excluded by the
parenthetical to clause (i) of this clause (q) and all other information that is made
available to stockholders; and

 

 

     (iii) Upon the reasonable request of any Lender, an adequate number of copies of
the prospectuses to supply to any other party requiring such prospectuses;

and the Company, upon the reasonable request of any Lender, will meet with such Lender or a
representative thereof at the Company’s headquarters to discuss all information relevant for
disclosure in the Registration Statement covering the Registrable Securities and will otherwise
cooperate with Lender conducting an investigation for the purpose of reducing or eliminating
Lender’s exposure to liability under the Securities Act, including the reasonable production of
information at the Company’s headquarters.

     (r) Piggyback Registration Rights. In the event that the Company shall determine
to prepare and file with the SEC a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity securities, other
than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) relating to equity
securities to be issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee benefit plans, then
the Company shall send to each Lender written notice of such determination and, if within fifteen
(15) days after receipt of such notice, any Lender shall so request in writing, the Company shall
include in such registration statement all or any part of such Registrable Securities which such
Lender requests to be registered to the extent the Company may do so without violating registration
rights of others which exist as of the date of this Agreement, subject to customary underwriter
cutbacks applicable to all holders of registration rights and subject to obtaining such Lender’s
cooperation substantially on the terms set forth above in this Section 5.

     6. No Shorting. Each Lender agrees that it and its Affiliates will not and will
not cause any person or entity, directly or indirectly, to, engage in “short sales” of the Common
Stock or any other hedging strategies with respect to the Common Stock, as long as the Note or any
part of the Term Loan principal balance shall be outstanding.

     7. Arbitration. In the event of any and all disagreements and controversies arising
from this Agreement, such disagreements and controversies shall be subject to binding arbitration
as arbitrated in accordance with the then current Commercial Arbitration Rules of the American
Arbitration Association in Chicago, Illinois before one neutral arbitrator. Either party may apply
to the arbitrator seeking injunctive relief until the arbitration award is rendered or the
controversy is otherwise resolved. Without waiving any remedy under this Agreement, either party
may also seek from any court having jurisdiction any interim or provisional relief that is
necessary to protect the rights or property of that party, pending the establishment of the
arbitral tribunal (or pending the arbitral tribunal’s determination of the merits of the
controversy). In the event of any such disagreement or controversy, neither party shall directly
or indirectly reveal, report, publish or disclose any information relating to such disagreement or
controversy to any person, firm or corporation not expressly authorized by the other party to
receive such information or use such information or assist any other person in doing so, except to
comply with actual legal obligations of such party, or unless such disclosure is directly related
to an arbitration proceeding as provided herein, including, but not limited to, the prosecution or
defense of any claim in such arbitration. The costs and expenses of the arbitration (excluding
attorneys’ fees) shall be paid by the non-prevailing party or as determined by the arbitrator.

 

 

     8. Miscellaneous.

     (a) All of the WHEREAS clauses and other recitals at the beginning of this Agreement are
hereby incorporated into and made part of this Agreement.

     (b) This Agreement shall be binding upon, and shall inure solely to the benefit of, each of
the parties hereto, and each of their respective heirs, executors, administrators, successors and
permitted assigns, and no other person shall acquire or have any right under or by virtue of this
Agreement. No Lender shall assign its rights under this Agreement except in connection with an
assignment under the Loan Agreement permitted by the terms thereof.

     (c) This Agreement may be amended only by written execution by all parties. No waiver of any
provision of this Agreement shall in any event be effective unless the same shall be in writing and
acknowledged by the party against whom enforcement is sought, and then any such waiver shall be
effective only in the specific instance and for the specific purpose for which given.

     (d) The descriptive headings of the several sections and paragraphs of this Agreement are
inserted for convenience only and do not constitute a part of this Agreement.

     (e) All questions concerning the construction, validity, enforcement and interpretation of
this Agreement shall be governed by the internal laws of the State of Illinois, without giving
effect to any choice of law or conflict of law provision or rule (whether of the State of Illinois
or any other jurisdiction) that would cause the application of the laws of any jurisdiction other
than the State of Illinois.

     (f) Wherever possible, each provision of this Agreement shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this Agreement shall be
prohibited by, unenforceable or invalid under any jurisdiction, such provision shall as to such
jurisdiction, be severable and be ineffective to the extent of such prohibition or invalidity,
without invalidating the remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction.

     (g) This Agreement may be executed in one or more counterparts, all of which shall be deemed
but one and the same agreement and each of which shall be deemed an original. Delivery by
facsimile of an executed counterpart of this Agreement shall be effective as an original executed
counterpart hereof and shall be deemed a representation that an original executed counterpart
hereof will be delivered.

     (h) THE PARTIES HERETO, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH
COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY, ANY RIGHT TO A TRIAL BY
JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT.

 

 

     (i) ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT
SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED
STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED THAT NOTHING IN THIS
AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE LENDER FROM BRINGING SUIT OR TAKING OTHER LEGAL
ACTION IN ANY OTHER JURISDICTION. EACH PARTY HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE

commercial banks in the City of Chicago are authorized or required by law to remain closed.

     “Fair Market Value” means, the fair market value of a share of Common Stock as of a
particular date (the “Determination Date”) as follows:

     (a) If the Common Stock is traded on the American Stock Exchange or another

respectively, reported for the last Business Day immediately preceding the
Determination Date.

 

 

     (b) If the Common Stock is not traded on the American Stock Exchange or another
national exchange or on the Nasdaq but is traded on the NASD OTC Bulletin Board,
then the mean of the average of the closing bid and asked prices reported for the
last Business Day immediately preceding the Determination Date.

     (c) Except as provided in clause (d) of this definition below, if the Common

pursuant to the Company’s charter, then all amounts to be payable per share to
holders of the Common Stock pursuant to the charter in the event of such
liquidation, dissolution or winding up, plus all other amounts to be payable per

     2. Exercise of Warrant.

     (a) Subject to the terms and conditions hereof, this Warrant may be exercised by the
Holder, in whole or in part, during normal business hours on any Business Day on or after
the date hereof and prior to 5:00 P.M. Chicago Time on the Expiration Date by

     (i) delivery of a duly executed written notice, in the form of the subscription
notice attached as Exhibit A hereto (the “Exercise Notice”), of such
Holder’s election to exercise this Warrant, which notice shall specify the number of
Warrant Shares to be purchased;

     (ii) payment to the Company of an amount equal to the Warrant Exercise Price
multiplied by the number of Warrant Shares as to which this Warrant is being
exercised (the “Aggregate Exercise Price”), either in cash or by certified check or
wire transfer of immediately available funds or by delivery of Warrant Shares
receivable upon exercise of this Warrant in accordance with Section 2(b) below; and

     (iii) delivery to the Company of this Warrant (or an indemnity and evidence
with respect to this Warrant in the case of its loss, theft, mutilation or
destruction as provided in Section 11).

In the event of any exercise of the rights represented by this Warrant in compliance with this
Section 2(a), the Company shall, on or before the tenth (10th) Business Day following
the date of its receipt of the Exercise Notice, the Aggregate Exercise Price and this Warrant (or
an indemnity and evidence with
respect to this Warrant in the case of its loss, theft, mutilation or destruction as provided in
Section 11) (the “Exercise Delivery Documents”), deliver at the Company’s expense to the Holder, a
certificate or

 

 

certificates for the Warrant Shares so purchased, in such denominations as may be
requested by Holder and registered in the name of Holder. Upon the Company’s receipt of the
Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become
the holder of record of the Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date of delivery of certificates evidencing such Warrant Shares.

          (b) Notwithstanding any provisions herein to the contrary, if the Fair Market Value of one
share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth
below), in lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal
to the value (as determined below) of this Warrant (or the portion thereof being exercised) by
surrender of this Warrant at the principal office of the Company together with the properly
endorsed Exercise Notice in which event the Company shall issue to the Holder a number of shares of
Common Stock computed using the following formula:

	 	 	 	 	 	 	 
	X

	 	=
	Y	(A-B)
 

A
	 	 

          Where X = the number of shares of Common Stock to be issued to the Holder

	 	Y=	 	 the number of shares of Common Stock purchasable under the
Warrant or, if only a portion of the Warrant is being exercised, the portion of
the Warrant being exercised (at the date of such calculation)
	 
	 	A=	 	 the Fair Market Value of one share of the Company’s Common
Stock (at the date of such calculation)
	 
	 	B=	 	 Exercise Price (as adjusted to the date of such calculation)

 

 

          (c) Unless the rights represented by this Warrant shall have expired or shall have been fully
exercised, the Company shall, as soon as practicable and in no event later than ten (10) Business
Days after any exercise and at its own expense, issue a new Warrant identical in all respects to
this Warrant exercised, except it shall represent rights to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under this Warrant exercised, less the number of
Warrant Shares with respect to which this Warrant is exercised.

          (d) No fractional shares of Common Stock are to be issued upon the exercise of this Warrant,
but rather the number of shares of Common Stock issued upon exercise of this Warrant shall be
rounded up or down to the nearest whole number.

     3. Covenants. The Company hereby represents, covenants and agrees as follows:

     (a) This Warrant is, and any Warrants issued in substitution for or
replacement of this Warrant will upon issuance be, duly authorized and validly issued.

     (b) All Warrant Shares which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully paid and
nonassessable.

     (c) The Company has full power and authority to enter into this Warrant, and to
issue and deliver this Warrant and the Warrant Shares, and to incur and perform fully the
obligations provided herein, all of which have been duly authorized by all necessary
corporate action.

     (d) This Warrant has been duly executed and delivered and is the valid and binding
obligation of the Company enforceable in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency, moratorium and other similar laws
affecting creditors’ rights generally and by general principles of equity.

     4. Taxes. The Company shall pay any and all taxes, except income taxes, which may be
payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant.

     5. Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein,
this Warrant shall not entitle Holder to vote or receive dividends or any other rights of a
stockholder of the Company, including, without limitation, any right to vote, give or withhold
consent to any corporate action (whether a reorganization, issue of stock, reclassification of
stock, consolidation, merger, conveyance or otherwise), receive notice of meetings or receive
subscription rights.

     6. Representations of Holder. The Holder, by the acceptance hereof, represents and
warrants that it:

     (a) is acquiring this Warrant and the Warrant Shares solely for its own account, for
investment and not with a view towards the distribution or resale thereof in violation of
the Securities Act or any applicable state securities laws;

     (b) has received such documents, materials and information as the Holder deems
necessary or appropriate for evaluation of the acquisition of this Warrant and the right to
acquire Warrant Shares hereunder;

     (c) is an “accredited investor” as such term is defined in Rule 501 of Regulation D
promulgated under the Securities Act and has such knowledge and experience in financial and

 

 

business matters that it is capable of evaluating the merits and risks of an investment
in this Warrant and the Warrant Shares;

     (d) understands that no U.S. federal, state or regulatory agency has recommended,
approved or endorsed, or passed upon the fairness or suitability of, an investment in this
Warrant or the Warrant Shares or passed up on the accuracy or adequacy of the information
provided to the Holder; and

     (e) recognizes that an investment in the Warrant Shares involves a high degree of
financial risk, and that it can bear the economic risk of losing its entire investment in
the Warrant Shares and has sought, or will seek, such accounting, legal and tax advice as it
has considered, or will consider, necessary to make an informed investment decision with
respect to its acquisition of this Warrant and of any Warrant Shares.

If the Holder cannot make any of the foregoing representations at the time of any exercise of this
Warrant because it would be factually incorrect at that time, the Holder shall so notify the
Company, and it shall be a condition to the Holder’s exercise of this Warrant at that time that the
Company receive such other assurances as the Company then considers reasonably necessary to assure
the Company that the issuance of the Warrant Shares upon such exercise of this Warrant at such time
shall not violate the Securities Act or any state securities laws.

     7. Restriction on Transfer.

          (a) This Warrant and the rights granted to Holder are transferable, in whole or in part, upon
surrender of this Warrant, together with a properly executed transfer endorsement in the form of
Exhibit B attached hereto; provided, however, that any transfer or assignment shall
be subject to the approval of the Company, such approval not to be unreasonably withheld, and the
conditions set forth in Section 7(b) below.

          (b) Holder represents and warrants that it understands that the Company is under no obligation
to register this Warrant or, except as set forth in Section 8 below, any of the Warrant Shares,
under the Securities Act and that this Warrant and Warrant Shares will be characterized as
“restricted securities” under the Securities Act because they are being acquired from the Company
in a transaction not involving a public offering. The Holder also represents and warrants that it
understands that neither the Warrant nor the Warrant Shares may be offered for sale, sold, assigned
or transferred unless (a) at that time they have been registered pursuant to an effective
registration statement under the Securities Act and applicable state securities laws, or (b) the
Holder shall have delivered to the Company a written opinion of counsel, in form, substance and
scope reasonably acceptable to the Company, to the effect that the securities to be offered for
sale, sold, assigned or transferred are being offered for sale, sold, assigned or transferred
pursuant to an exemption from such registration.

          (c) Unless upon their issuance such Warrant Shares are then registered under the Securities
Act pursuant to an effective registration statement, any certificates representing Warrant Shares
issued in accordance with this Warrant shall bear a legend substantially in the following form:

THE SHARES OF COMMON STOCK OF LIME ENERGY CO. (THE “COMPANY”) REPRESENTED BY THIS
CERTIFICATE (THE “SHARES”) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR
ASSIGNED UNLESS (A) SUBSEQUENTLY REGISTERED PURSUANT TO AN

 

 

EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR (B) THE HOLDER HEREOF SHALL HAVE
DELIVERED TO THE COMPANY A WRITTEN OPINION OF COUNSEL, IN FORM, SUBSTANCE AND SCOPE
REASONABLY ACCEPTABLE TO THE COMPANY, TO THE EFFECT THAT THE SHARES TO BE OFFERED FOR SALE,
SOLD, TRANSFERRED OR ASSIGNED ARE BEING OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED
PURSUANT TO AN EXEMPTION FROM SUCH REGISTRATION.

     8. Registration of Warrant Shares. The Company has granted Holder rights to seek
to register the Warrant Shares under the Securities Act, as more fully set forth in that certain
Investor Rights Agreement dated as of May 29, 2007 by and between the Company and Holder.

     9. Adjustment of Warrant Exercise Price and Number of Warrant Shares upon Subdivision or
Combination of Common Stock.

          (a) If the Company at any time after the date of issuance of this Warrant subdivides (by any
stock split or stock dividend of its Common Stock) its outstanding shares of Common Stock into a
greater number of shares of Common Stock, the Warrant Exercise Price in effect immediately prior to
such subdivision will be proportionately reduced and the number of Warrant Shares obtainable upon
exercise of this Warrant will be proportionately increased. If the Company at any time after the
date of issuance of this Warrant combines (by reverse stock split or otherwise) its outstanding
shares of Common Stock into a smaller number of shares of Common Stock, the Warrant Exercise Price
in effect immediately prior to such combination will be proportionately increased and the number of
Warrant Shares obtainable upon exercise of this Warrant will be proportionately decreased. Any
adjustment under this Section 9(a) shall become effective at the close of business on the date the
subdivision or combination becomes effective.

          (b) Upon any adjustment of the Warrant Exercise Price or number of issuable Warrant Shares
pursuant to Section 9(a), the Company will give written notice thereof to the Holder, setting forth
in reasonable detail the calculation of such adjustment.

     10. Reorganization, Reclassification, Consolidation, Merger or Sale. If at any time,
as a result of:

          (a) a capital reorganization or reclassification (other than a subdivision or combination
provided for in Section 9), or

          (b) a merger or consolidation of the Company with another corporation (whether or not the
Company is the surviving corporation) or sale of substantially all of the Company’s stock, the
Common Stock issuable upon exercise of this Warrant shall be changed into or exchanged for the same
or a different number of shares of any class or classes of capital stock of the Company or any
other Person, or other securities convertible into such shares, then, as a part of such
reorganization, reclassification, merger, consolidation or sale, appropriate adjustments shall be
made in the terms of this Warrant (or of any securities into which this Warrant is exercised or for
which this Warrant is exchanged), so that Holder shall thereafter be entitled to receive, upon
exercise of this Warrant or of such substitute securities, the kind and amount of shares of stock,
other securities, money and property which Holder would have received at the time of such capital
reorganization, reclassification, merger, consolidation or sale, if Holder had exercised this
Warrant immediately prior to such capital reorganization, reclassification, merger, consolidation
or sale. This Warrant, including, without limitation, the provisions of this Section 10 will be
binding upon any entity succeeding to the Company

 

 

by merger, consolidation or acquisition of all or
substantially all of the Company’s assets. The provisions of this Section 10 shall similarly apply
to (x) successive capital reorganizations, reclassifications, mergers, consolidations and sale and (y)
the securities of any other Person that are at the time receivable upon the exercise of this
Warrant.

     11. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen,
mutilated or destroyed, the Company shall promptly, on receipt of evidence reasonably satisfactory
to the Company of the ownership of, and the loss, theft, mutilation or destruction of, this
Warrant, and an indemnity reasonably satisfactory to the Company (or in the case of a mutilated
Warrant, the Warrant), issue in lieu thereof a new Warrant of like denomination and tenor as this
Warrant so lost, stolen, mutilated or destroyed.

     12. Notice. Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Warrant must be in writing and will be deemed to have
been made upon receipt when delivered personally, via pre-paid overnight courier or by certified
mail, postage pre-paid, return receipt requested. The addresses for such communications shall be:

          If to the Company:

Elk Grove Village, IL 60007

Attention: General Counsel

          If to the Holder:

or such other address as the Company or Holder, as applicable, may specify in written notice given
to the other party in accordance with this Section 12.

     13. Amendments. This Warrant and any term hereof may be changed, waived,
discharged, or terminated only by an instrument in writing signed by the party hereto against which
enforcement of such change, waiver, discharge or termination is sought.

     14. Expiration. This Warrant, in all events, shall be wholly void and of no effect
after 5:00 P.M. Chicago Time on the Expiration Date.

     15. Successors and Assigns. The terms and provisions of this Warrant shall inure to
the benefit of, and be binding upon, the Company and the Holder and their respective successors and
permitted assigns.

     16. Descriptive Headings; Governing Law. The descriptive headings of the several
sections and paragraphs of this Warrant are inserted for convenience only and do not constitute a
part of this Warrant. All questions concerning the construction, validity, enforcement and
interpretation of this Warrant shall be governed by the internal laws of the State of Illinois,
without giving effect to any choice

 

 

of law or conflict of law provision or rule (whether of the
State of Illinois or any other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Illinois.

     17. Arbitration. In the event of any and all disagreements and controversies arising
from this Warrant, such disagreements and controversies shall be subject to binding arbitration as
arbitrated in accordance with the then current Commercial Arbitration Rules of the American
Arbitration Association in Chicago, Illinois before one neutral arbitrator. Either party may apply
to the arbitrator seeking injunctive relief until the arbitration award is rendered or the
controversy is otherwise resolved. Without waiving any remedy under this Warrant, either party may
also seek from any court having jurisdiction any interim or provisional relief that is necessary to
protect the rights or property of that party, pending the establishment of the arbitral tribunal
(or pending the arbitral tribunal’s determination of the merits of the controversy). In the event
of any such disagreement or controversy, neither party shall directly or indirectly reveal, report,
publish or disclose any information relating to such disagreement or controversy to any person,
firm or corporation not expressly authorized by the other party to receive such information or use
such information or assist any other person in doing so, except to comply with actual legal
obligations of such party, or unless such disclosure is directly related to an arbitration
proceeding as provided herein, including, but not limited to, the prosecution or defense of any
claim in such arbitration. The costs and expenses of the arbitration (excluding attorneys’ fees)
shall be paid by the non-prevailing party or as determined by the arbitrator.

and the holders of the Term Notes due May 31, 2010, issued by the Company (such holder is referred
to herein as the “Lender,” and collectively as the “Lenders”).

W I T N E S S E T H:

     WHEREAS, Lenders and the Company are parties to that certain Loan Agreement dated as of the
date hereof pursuant to which Lenders have agreed to make certain loans available to the Company,
on and subject to the terms and conditions set forth therein (the “Loan Agreement”); and

relating to the obligations of the Company to Lenders and to certain other matters, all as more

     1. Definitions. Terms which are defined in the Loan Agreement and which are used in
capitalized form herein and not otherwise specifically defined herein are used with the meanings

written notice shall be delivered at the address for the Company applicable under the Loan
Agreement and shall state the amount of principal and interest being converted and the applicable
conversion date (which shall not be earlier than the date upon which such notice is given to the
Company).

     (b) The outstanding principal balance of the Loan and all accrued unpaid interest thereon
shall automatically be converted into shares of Common Stock at the Conversion Price, without
notice or other action by the Company or Lenders, if, at any time after May 31, 2008, for twenty

Common Stock being issued registered in the name of such Lender.

     (e) Upon the Company’s receipt of a notice of conversion from a Lender under clause (a) above,
or upon automatic conversion under clause (b) above, such Lenders shall be deemed for all corporate
purposes to have become the holder of record of the shares of Common Stock with respect to which
such conversion occurs (which, for purposes of clause (a) shall be the date specified in the notice
given with respect to a conversion under clause (a)), irrespective of the date of delivery of
certificates evidencing such shares.

     4. Legends. Unless upon their issuance such shares of Common Stock are then

certificates representing shares of Common Stock issued under Section 2 or Section 3 hereof shall

THE SHARES OF COMMON STOCK OF LIME ENERGY CO. (THE “THE COMPANY”) REPRESENTED BY
THIS CERTIFICATE (THE “SHARES”) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED FOR SALE, SOLD,
TRANSFERRED OR ASSIGNED UNLESS (A) SUBSEQUENTLY REGISTERED PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS
OR (B) THE HOLDER HEREOF SHALL HAVE DELIVERED TO THE COMPANY A WRITTEN OPINION OF
COUNSEL, IN FORM, SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE COMPANY, TO THE
EFFECT THAT THE SHARES TO BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED ARE
BEING OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED PURSUANT TO AN EXEMPTION FROM
SUCH REGISTRATION.

     5. Registration Rights. The Company shall:

     (a) Demand Registration. In the event the Company shall receive from a Lender a
written request that the Company effect any registration, qualification or compliance under the
Securities Act with respect to at least thirty-three percent (33%) of the aggregate Warrant Shares
and the shares of Common Shares which have been issued to such Lender pursuant to Section 2
or Section 3 of this Agreement (“Agreement Shares,” and, collectively with the
Warrant Shares, the “Registrable Securities”) for resale by the Lenders from time to time
through the over-the-counter market or in privately-negotiated transactions or otherwise, the
Company, as soon as practicable, shall (i) use its best efforts to prepare and file with the SEC a
registration statement (the “Registration Statement”), and (ii) provide to each Lender a
draft of the Registration Statement for review and comment within thirty (30) days after receipt of
the initial Lender’s request for such registration. Notwithstanding the foregoing, the Company
shall have no obligations pursuant to this Section 5(a) unless the number of shares to be
registered for the Lenders pursuant to this Section 5(a) shall be at least 1,000,000 in the
aggregate, which amount shall be subject to adjustment for stock splits and other similar pro rata
combinations of the Company’s common stock.

Page 3 of 11

 

     (b) Subject to the provisions of clause (g) below, and to receipt of all necessary information
from the Lenders, the Company uses reasonable efforts to cause the Registration
Statement to be declared effective as promptly as practicable after filing thereof, and in any
event within ninety (90) days after filing thereof.

     (c) Use reasonable efforts to keep the Registration Statement continuously effective under the
Securities Act until the date which is the earlier of the date (i) when all Registrable Securities
have been sold, or (ii) the date that is the eighteenth (18th) month anniversary of the date the
Registration Statement shall have been declared effective.

     (d) File any documents required of the Company for customary “blue sky” clearance in Illinois.

     (e) File with the SEC in a timely manner the reports and other documents required to be filed
by it under the Securities Act and the Securities Exchange Act (or, if the Company is not required
to file such reports, it will, upon the request of any Lender, make publicly available other
information so long as necessary to permit sales by Lenders under Rule 144), all to the extent
required to enable Lenders to sell the Registrable Securities from time to time without
registration under the Securities Act within the limitations provided by Rule 144;
provided, however, that nothing in this Agreement shall require the Company to file reports
under the Securities Act or the Securities Exchange Act, to register any of its securities under
the Securities Exchange Act, or to make publicly available any information concerning the Company
at any time when it is not required by law or by any other agreement by which it is bound to do any
of the foregoing.

     (f) All expenses relating to the registration and offering of the Registrable Securities
pursuant to this Section 5 shall be borne by the Company, except that Lenders shall bear
underwriting and selling commissions attributable to the Registrable Securities being registered
and any transfer taxes on shares being sold by Lenders.

     (g) In addition to and without limitation of any other covenant of Lenders contained in this
Agreement, each Lender who desires to have its Registrable Securities registered pursuant to this
Section 5 shall:

     (i) Furnish to the Company, upon the Company’s request, all information regarding
Lenders and the intended distribution of the Registrable Securities for the purpose of
preparing such Registration Statement, to the extent that such information is required to
comply with applicable legal requirements; and

     (ii) Upon the Company’s request, notify the Company of the number of Registrable
Securities that have been sold and remain to be sold pursuant to any the Registration
Statement; and

     (iii) promptly notify the Company when all registered Registrable Securities have been
sold.

     (h) Lender agrees not to effect any disposition of any Registrable Securities or the right to
purchase any Registrable Securities that would constitute an offer or sale within the meaning of
the

Page 4 of 11

 

Securities Act except as contemplated in this Section 5 or pursuant to an exemption
from registration under the Securities Act.

     (i) The Company will promptly notify Lender at any time when a prospectus relating to
Registrable Securities is required to be delivered under the Securities Act of the happening of any
event as a result of which the prospectus included in such Registration Statement, as then in
effect, includes an untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make the statements therein not misleading or incomplete in
the light of the circumstances then existing.

     (j) The Company will furnish to Lender with respect to the Registrable Securities registered
under the Registration Statement (and to each underwriter, if any, of such Registrable Securities)
such number of copies of the Registration Statement and any amendment or supplement thereto and of
prospectuses and preliminary prospectuses in conformity with the requirements of the Securities Act
as Lender shall reasonably request.

     (k) The Company shall prepare and file with the SEC such amendments and supplements to such
Registration Statement and the prospectus used in connection therewith as may be necessary so that,
as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading or incomplete in the
light of the circumstances then existing; provided, however, the Company may,
subject to the last sentence of this clause (k), temporarily suspend the use of the prospectus
forming a part of such registration statement in the event that, and during such period as,

     (i) the Company is engaged in confidential negotiations or other confidential business
activities, disclosure of which would be required to be included or incorporated by
reference in such prospectus or registration statement, and

     (ii) the Board of Directors of the Company determines in good faith that such
disclosure would have a material adverse effect on any such confidential negotiations or
other confidential business activities or would be materially detrimental to the Company.

In such event, subject to the last sentence of this clause (k), the Company may suspend the use of
such prospectus until such time as an amendment to such Registration Statement has been filed by
the Company and declared effective by the SEC, or until such time as the Company has filed an
appropriate report with the SEC pursuant to the Securities Exchange Act. Anything herein to the
contrary notwithstanding, the Company does not have the right to suspend the use of such prospectus
or otherwise restrict Lender’s ability to sell or otherwise transfer the Registrable Securities for
a period of more than 90 days (which need not be consecutive days) in any twelve month period.

     (l) The Company will promptly inform Lender when any stop order by the SEC has been issued
with respect to the Registrable Securities and use its best efforts to promptly cause such stop
order to be withdrawn.

Page 5 of 11

 

     (m) The Company will cause all Registrable Securities registered pursuant to such Registration
Statement to be listed on each securities exchange or market system on which the Company’s Common
Stock then is listed.

     (n) The Company will take such other actions as may be reasonably necessary to effect the
registration of the resale of the Registrable Securities in accordance with the terms of this
Agreement, to allow such Registrable Securities to trade in the same market system or exchange
where the Company’s Common Stock then trades, and to comply with all rules and regulations of the
SEC applicable thereto.

     (o) Indemnification and Contribution. For the purpose of this clause (o), the term
“Lender Party” shall include the Lender and its respective officers, directors, and any
Person which controls Lender, and the term “Registration Statement” shall include the
Registration Statement to be filed pursuant to this Section 5 and any final prospectus,
supplement or amendment included in or relating to such Registration Statement.

     The Company agrees to indemnify and hold harmless each Lender Party from and against any
losses, claims, damages or liabilities to which such Person may become subject (under the
Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon any untrue statement or alleged
untrue statement of a material fact contained in a Registration Statement or the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading or arise out of any failure by the Company to fulfill
any undertaking included in a Registration Statement and the Company will reimburse such Lender
Party for any reasonable legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim as such expenses are incurred;
provided, however, that the Company shall not be liable in any such case to the extent that
such loss, claim, damage or liability arises out of, or is based upon, any such untrue statement or
omission made in such Registration Statement in reliance upon written information furnished to the
Company by or on behalf of Lender or any Lender Party expressly for use in preparation of the
Registration Statement, or the failure of such Lender Party to comply with the covenants and
agreements of the Lender contained in this Section 5 respecting sale of any Registrable
Securities or any statement or omission in any prospectus that is corrected or made not misleading
in any subsequent prospectus that was delivered to Lender or such Lender Party prior to the
pertinent sale or sales by such Lender Party.

     Each Lender agrees, severally and jointly, to indemnify and hold harmless the Company (and
each person, if any, who controls the Company within the meaning of Section 15 of the Securities
Act, and each of its officers and directors who sign the Registration Statement) from and against
any losses, claims, damages or liabilities to which the Company (or any such officer, director or
controlling person) may become subject (under the Securities Act or otherwise), insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of,
or are based upon, any failure by such Lender or any respective Lender Party to comply with the
covenants and agreements of such Lender contained in Section 4 hereof respecting sale of
any Registrable Securities, or any untrue statement or alleged untrue statement of a material fact
contained (or incorporated by reference), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, in the

Page 6 of 11

 

Registration Statement on the effective date thereof if such untrue statement
was made in reliance upon and in conformity with written information furnished by or on behalf of
such Lender or any respective Lender Party for use in preparation of such Registration Statement.
Each Lender will reimburse, severally and not jointly, the Company (or such officer, director or
controlling person), as
the case may be, for any legal or other expenses reasonably incurred in investigating,
defending or preparing to defend any such action, proceeding or claim. In no event shall the
liability of any Lender hereunder be greater in amount than the dollar amount of the net proceeds
received by such Lender and the respective Lender Parties upon the sale of the Registrable
Securities giving rise to such indemnification obligation.

     Promptly after receipt by any indemnified person of a notice of a claim or the beginning of
any action in respect of which indemnity is to be sought against an indemnifying person pursuant to
this clause (o), such indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in
case any such action shall be brought against an indemnified person, such indemnifying person shall
be entitled to participate therein, and, to the extent it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the
indemnifying person to such indemnified person of its election to assume the defense thereof, such
indemnifying person shall not be liable to such indemnified person for any legal expenses
subsequently incurred by such indemnified person in connection with the defense thereof;
provided, however, that if there exists or shall exist a conflict of interest that would
make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to
represent both the indemnified person and such indemnifying person, the indemnified person shall be
entitled to retain its own counsel (in addition to local counsel) at the expense of such
indemnifying person; provided, further, that no indemnifying person shall be
responsible for the fees and expenses of more than one separate counsel for all indemnified parties
collectively without regard to the number of Lenders or Lender Parties. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its written consent, but,
if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party or parties in accordance with the provisions of
this clause (o).

     If the indemnification provided for in this clause (o) from the indemnifying person is
determined by a court of competent jurisdiction to be unavailable to an indemnified person
hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein,
then the indemnifying person, in lieu of indemnifying such indemnified person, shall contribute to
the amount paid or payable by such indemnified person as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the
indemnifying person and indemnified persons in connection with the actions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant equitable
considerations. The relative fault of such indemnifying person and indemnified persons shall be
determined by reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact or omission or alleged omission, has been
made by, or relates to information supplied by, such indemnifying person or indemnified persons,
and the parties’ relative intent, knowledge, access to information and opportunity to correct or
prevent such action. The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include, subject to the
limitations set forth in this clause (o), any

Page 7 of 11

 

reasonable legal or other fees or expenses reasonably
incurred by such party in connection with any investigation or proceeding. The parties hereto
agree that it would not be just and equitable if contribution pursuant to this clause (o) were
determined by pro rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred
to in the immediately preceding paragraph. Notwithstanding the provisions of this clause (o),
no Lender shall be required to contribute any amount in excess of the dollar amount of the gross
proceeds received by such Lender and the respective Lender Parties upon the sale of the Registrable
Securities giving rise to such contribution obligation. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation.

     (p) The conditions precedent imposed upon the transferability of the Registrable Securities by
this Section 5 shall cease and terminate as to any particular number of the Registrable
Securities when such Registrable Securities shall have been effectively registered under the
Securities Act and sold or otherwise disposed of in accordance with the intended method of
disposition set forth in the Registration Statement covering such Registrable Securities or at such
time as an opinion of counsel satisfactory to the Company shall have been rendered to the effect
that such conditions are not necessary in order to comply with the Securities Act.

     (q) So long as a registration statement is effective covering the resale of any Registrable
Securities, the Company will furnish to each Lender:

     (i) As soon as practicable after available (but in the case of the Company’s Annual
Report on Form 10-K, within 120 days after the end of each fiscal year of the Company), one
copy of (i) its Annual Report on Form 10-K or equivalent form (which shall contain financial
statements audited in accordance with generally accepted accounting principles by a firm of
certified public accountants), and (ii) a full copy of the Registration Statement covering
the Registrable Securities which are registered thereby (the foregoing, in each case,
excluding exhibits);

     (ii) Upon the reasonable request of any Lender, any exhibits excluded by the
parenthetical to clause (i) of this clause (q) and all other information that is made
available to stockholders; and

     (iii) Upon the reasonable request of any Lender, an adequate number of copies of the
prospectuses to supply to any other party requiring such prospectuses;

and the Company, upon the reasonable request of any Lender, will meet with such Lender or a
representative thereof at the Company’s headquarters to discuss all information relevant for
disclosure in the Registration Statement covering the Registrable Securities and will otherwise
cooperate with Lender conducting an investigation for the purpose of reducing or eliminating
Lender’s exposure to liability under the Securities Act, including the reasonable production of
information at the Company’s headquarters.

     (r) Piggyback Registration Rights. In the event that the Company shall determine to
prepare and file with the SEC a registration statement relating to an offering for its own account
or

Page 8 of 11

 

the account of others under the Securities Act of any of its equity securities, other than on
Form S-4 or Form S-8 (each as promulgated under the Securities Act) relating to equity securities
to be issued solely in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit plans, then the
Company shall send to each Lender written notice of such determination and, if within fifteen (15)
days after receipt of such
notice, any Lender shall so request in writing, the Company shall include in such registration
statement all or any part of such Registrable Securities which such Lender requests to be
registered to the extent the Company may do so without violating registration rights of others
which exist as of the date of this Agreement, subject to customary underwriter cutbacks applicable
to all holders of registration rights and subject to obtaining such Lender’s cooperation
substantially on the terms set forth above in this Section 5.

     6. No Shorting. Each Lender agrees that it and its Affiliates will not and will not
cause any person or entity, directly or indirectly, to, engage in “short sales” of the Common Stock
or any other hedging strategies with respect to the Common Stock, as long as the Note or any part
of the Term Loan principal balance shall be outstanding.

     7. Arbitration. In the event of any and all disagreements and controversies arising
from this Agreement, such disagreements and controversies shall be subject to binding arbitration
as arbitrated in accordance with the then current Commercial Arbitration Rules of the American
Arbitration Association in Chicago, Illinois before one neutral arbitrator. Either party may apply
to the arbitrator seeking injunctive relief until the arbitration award is rendered or the
controversy is otherwise resolved. Without waiving any remedy under this Agreement, either party
may also seek from any court having jurisdiction any interim or provisional relief that is
necessary to protect the rights or property of that party, pending the establishment of the
arbitral tribunal (or pending the arbitral tribunal’s determination of the merits of the
controversy). In the event of any such disagreement or controversy, neither party shall directly
or indirectly reveal, report, publish or disclose any information relating to such disagreement or
controversy to any person, firm or corporation not expressly authorized by the other party to
receive such information or use such information or assist any other person in doing so, except to
comply with actual legal obligations of such party, or unless such disclosure is directly related
to an arbitration proceeding as provided herein, including, but not limited to, the prosecution or
defense of any claim in such arbitration. The costs and expenses of the arbitration (excluding
attorneys’ fees) shall be paid by the non-prevailing party or as determined by the arbitrator.

     8. Miscellaneous.

     (a) All of the WHEREAS clauses and other recitals at the beginning of this Agreement are
hereby incorporated into and made part of this Agreement.

     (b) This Agreement shall be binding upon, and shall inure solely to the benefit of, each of
the parties hereto, and each of their respective heirs, executors, administrators, successors and
permitted assigns, and no other person shall acquire or have any right under or by virtue of this
Agreement. No Lender shall assign its rights under this Agreement except in connection with an
assignment under the Loan Agreement permitted by the terms thereof.

Page 9 of 11

 

     (c) This Agreement may be amended only by written execution by all parties. No waiver of any
provision of this Agreement shall in any event be effective unless the same shall be in writing and
acknowledged by the party against whom enforcement is sought, and then any such waiver shall be
effective only in the specific instance and for the specific purpose for which given.

     (d) The descriptive headings of the several sections and paragraphs of this Agreement are
inserted for convenience only and do not constitute a part of this Agreement.

     (e) All questions concerning the construction, validity, enforcement and interpretation of
this Agreement shall be governed by the internal laws of the State of Illinois, without giving
effect to any choice of law or conflict of law provision or rule (whether of the State of Illinois
or any other jurisdiction) that would cause the application of the laws of any jurisdiction other
than the State of Illinois.

     (f) Wherever possible, each provision of this Agreement shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this Agreement shall be
prohibited by, unenforceable or invalid under any jurisdiction, such provision shall as to such
jurisdiction, be severable and be ineffective to the extent of such prohibition or invalidity,
without invalidating the remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction.

     (g) This Agreement may be executed in one or more counterparts, all of which shall be deemed
but one and the same agreement and each of which shall be deemed an original. Delivery by
facsimile of an executed counterpart of this Agreement shall be effective as an original executed
counterpart hereof and shall be deemed a representation that an original executed counterpart
hereof will be delivered.

     (h) THE PARTIES HERETO, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH
COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY, ANY RIGHT TO A TRIAL BY
JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT.

     (i) ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS
AGREEMENT SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN
THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED THAT
NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE LENDER FROM BRINGING SUIT OR
TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION. EACH PARTY HEREBY EXPRESSLY AND IRREVOCABLY
SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES
DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET
FORTH ABOVE AND EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT
IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM.
