Re: Employment Agreement

On behalf of the Board of Directors of Polaris Industries Inc., a Minnesota corporation
(“Polaris”), I am writing regarding your continuing employment with Polaris. This letter agreement
(the “Agreement”) amends, restates, replaces and supersedes, effective as of January 1, 2006, that
letter agreement between you and Polaris dated January 31, 2005, and is written for the purpose of
setting forth the terms and conditions of your continued employment by Polaris and to protect
Polaris’ knowledge, expertise, and relationships and the confidential information Polaris has
developed about its customers, suppliers, products, operations and services.

	1.	 	Title and Position

During the term of your employment hereunder you shall be employed as Chief Executive Officer
of Polaris and, subject to the supervision and control of the Board of Directors of Polaris,
perform such duties, have such power and exercise such supervision and control with regard to the
business of Polaris as are commonly associated with or appropriate to the office of Chief Executive
Officer, including but not limited to the day-to-day general management, supervision and control of
all of the businesses and operations of Polaris and its subsidiaries. In discharging your duties
and responsibilities, you may also serve as an executive officer and/or director of any direct or
indirect subsidiary of Polaris. During the term of your employment you shall apply on a full-time
basis (allowing for ordinary course vacations and sick leave) all of your skill and experience to
the performance of your duties in your positions with Polaris and its subsidiaries. It is
understood that you may have other business investments and participate in other business ventures
which may, from time to time, require minor portions of your time, but which will not interfere or
be inconsistent with your duties under this letter agreement.

	2.	 	Term of Employment

Unless sooner terminated as provided in Section 5 below, your employment under the terms of
this Agreement shall commence as of January 1, 2006 and shall continue until December 31, 2007.

	 	(a)	 	Base Salary. During the term of your employment, you will be paid a
base annual salary (“Base Salary”) in the amount of $750,000, payable in accordance

increased during the term of your employment.

	 	(b)	 	Annual Cash Incentive Compensation. During the term of your
employment, you will continue to participate in Polaris’ Senior Executive Annual
Incentive Compensation Plan (the “Plan”). The Compensation Committee of the Board of
Directors will determine, in accordance with the Plan, on an annual basis the actual
amount of any Performance incentive award (“Annual Bonus”) to be awarded to you under
the Plan. During the term of your employment you will be eligible to receive a target
annual payment under the Plan equal to 200 percent of your Base Salary subject to the
performance criteria established by the Compensation Committee under the Plan.

	 	(c)	 	Supplemental Perquisites. During the term of your employment, you will

anniversary of the date of termination of your employment.

	 	(e)	 	Definitions. For purposes of this Agreement:

	 	(i)	 	“Cause” means (A) the willful and continued failure by you to
substantially perform your duties hereunder (other than any such failure
resulting from incapacity due to physical or mental illness) after a written
demand for substantial performance has been delivered by the Board of Directors
of Polaris which specifically specifies the manner in which the Board of
Directors believes you have not substantially performed your duties; (B) the
willful engaging by you in gross negligence, illegal conduct or gross
misconduct which is materially and demonstrably injurious to Polaris; (C) you
are convicted of, or enter a guilty or nolo contendere plea with respect to, a
felony; or (D) any other willful and material breach of this Agreement by you
that you have not remedied within a reasonable time after receipt of a written
notice from the Board of Directors of Polaris that specifically identifies such
breach.

For purposes of this paragraph, no act, or failure to act, on your part will
be deemed “willful” unless done, or omitted to be done, by you not in good
faith and without reasonable belief that your action or omission was in the
best interest of Polaris.

	 	(ii)	 	“Good Reason” means any of (A) a material reduction in the
scope of your authority and responsibility as an executive of Polaris (other
than isolated, insubstantial actions not taken in bad faith and which are
remedied by Polaris upon notice to Polaris, or as temporarily required due to
your illness or injury), (B) a reduction in your base compensation; (C) Polaris
requires your principal place of employment to be other than at its principal
executive offices; or (D) Polaris otherwise fails to perform any of its
material obligations to you.

	 	(f)	 	Waiver of Claims; Withholding. All amounts payable under this
Agreement will be net of any applicable requisite tax withholding and in lieu of any
other rights or claims you may have against Polaris including under the Change in
Control Agreement referred to in Section 4 above, all of which such rights or claims
you hereby waive.

All payments to be made under this Agreement will be less applicable withholding or
deductions.

	6.	 	Proprietary Information; Noncompetition

	 	(a)	 	Proprietary Information. Except with the prior written permission of
Polaris, you agree that you will not, through the actual date of any termination of
your employment with Polaris and for a period of 60 months thereafter, disclose or use
any Proprietary Information (as defined below) of Polaris or any of its subsidiaries of
which you become informed during your employment with Polaris, whether or not developed
by you, except as required by your duties to Polaris or any of its subsidiaries.
Proprietary Information means, as to Polaris or any of its subsidiaries, business
plans, operating plans, procedures or manuals, financial statements, projections or
reports, or other confidential information of the Company, excluding, however, (i) such
information which is then or later becomes generally available to the public other than
through you; (ii) such information which is received by you from a third party owing no
obligation of confidentiality to Polaris; and (iii) such information which has been or
is later disclosed by Polaris to an unrelated third party on a non-confidential basis.
Information does not lose its Proprietary Information status merely because it was
known by other persons or entities or because it did not entirely originate with
Polaris. Upon termination of your employment with Polaris for any reason, you agree to
deliver to Polaris all materials (in whatever form or format) that include Proprietary
Information. You agree and understand that the Proprietary Information and all
information contained therein shall be at all times the property of Polaris. Further,
upon termination of your employment for any reason, you agree to make available to any
person designated by Polaris or any of its subsidiaries all information concerning
pending or preceding transactions which may affect the operation of Polaris or any of
its subsidiaries about which you have knowledge.

	 	(b)	 	Noncompetition. It is mutually acknowledged that by virtue of your
employment hereunder, Polaris and its subsidiaries will divulge and make accessible to
you, and you will become possessed of, certain valuable and confidential information
concerning the business and operations of Polaris and its subsidiaries. Without
limitation it is also specifically acknowledged that great trust on the part of Polaris
and its subsidiaries will reside in you because your duties will include involvement in
the management, promotion and development of Polaris’ operations and business.
Accordingly, it is necessary to enter into the following protective agreements:

	 	(i)	 	You agree with Polaris and for the benefit of Polaris and its
subsidiaries through the actual date of termination of your employment, and for
a period of two years thereafter, you will not own or have any interest in and
will not, on your behalf or on the behalf of any third party, perform any
services for, directly or indirectly, any person or entity (a “Polaris
Competitor”) which engages in a business that Polaris or any of its
subsidiaries conducts or contemplates conducting in the near future at the time
of the termination of your employment (each, a “Competitive Activity”), except
that you may own up to 1% of the outstanding securities of any corporation if
such securities are registered under the Securities Exchange Act of 1934, as
amended and you may provide services for businesses of Polaris Competitors that
are not engaged in or provide goods or services to a Competitive Activity.

	 	(ii)	 	You agree that during your employment with Polaris and for a
period of two years following the termination of such employment that you will
not, either directly or indirectly, on your own behalf or in the service or on
behalf of others solicit, divert or hire away, or in any manner attempt to
solicit, divert or hire away any full-time employee of Polaris or any of its
subsidiaries, and whether or not such employment was pursuant to a written or
oral contract of employment and whether or not such employment was for a
determined period or was at-will.

	7.	 	Miscellaneous. 

You understand and agree that a breach by you of any of the provisions of this Agreement may
cause Polaris or its subsidiaries irreparable injury and damage which cannot be compensable by
receipt of money damages. You, therefore, expressly agree that Polaris and its subsidiaries shall
be entitled, in addition to any other remedies legally available to it, to injunctive and/or other
equitable relief to prevent a breach of this Agreement or any part hereof.

Neither this Agreement nor anything contained herein shall be construed as conferring upon you
or Polaris the right to your continued employment by Polaris after December 31, 2006.

All notices under this Agreement shall be in writing and shall be deemed given if delivered by
hand or mailed by registered or certified mail, return receipt requested, to the party to receive
the same at the address set forth below or such other address as may have been furnished by proper
notice.

Capitalized terms used but not otherwise defined herein shall have the meanings set forth in
Section 9.1.

per Unit (the “PER UNIT PURCHASE PRICE”) and on the other terms and conditions contained in this
Agreement.

TERMS OF AGREEMENT

In consideration of the mutual representations and warranties, covenants and agreements
contained herein, the parties hereto agree as follows:

ARTICLE 1

SUBSCRIPTION AND ISSUANCE OF SECURITIES

Agreement, the Issuer will issue and sell to the Investors and the Investors, severally and not
jointly, subscribe for and will purchase from the Issuer the number of Units set forth next to each
Investor’s name on the signature pages hereof for the aggregate purchase price set forth next to
such Investor’s name on the signature pages hereof (the “SUBSCRIPTION AMOUNT”). The purchase price
for each Unit shall be the Per Unit Purchase Price, which shall be equal to the sum of the Per
Share Purchase Price and the Per Warrant Share Purchase Price.

1.2 TRANSFER RESTRICTIONS. The Securities may be disposed of only in compliance with state and
federal securities laws. In connection with any transfer of Securities other than pursuant to an
effective Registration Statement, to the Issuer, or to an Affiliate of an Investor, the Issuer may
require the transferor thereof to provide to the Issuer an opinion of counsel selected by the
transferor, at the expense of the Investor transferring such Securities or the transferee, the form
and substance of which opinion shall be reasonably satisfactory to the Issuer, to the effect that
such transfer does not require registration of such transferred Securities under the Securities
Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the
terms of this Agreement and shall have the rights of an Investor under this Agreement.

1.3 LEGEND. Any certificate or certificates representing the Securities shall bear the following
legend:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, TRANSFERRED, OR
OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND IN COMPLIANCE WITH
APPLICABLE SECURITIES LAWS OF ANY STATE WITH RESPECT THERETO OR IN ACCORDANCE WITH
AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE ISSUER
THAT AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE AND ALSO MAY NOT BE SOLD,
TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH ANY APPLICABLE RULES
OF THE SECURITIES AND EXCHANGE COMMISSION. NOTWITHSTANDING THE FOREGOING, SUBJECT
TO COMPLIANCE WITH APPLICABLE SECURITIES LAWS, THE SECURITIES MAY BE PLEDGED IN
CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT
SECURED BY THE SECURITIES.

1.4 REMOVAL OF LEGENDS. During the period that a Registration Statement (as defined below)
covering the resale of the Shares and Warrant Shares, and if applicable the Additional Shares, is
effective under the Securities Act or if such Securities are being sold pursuant to Rule 144(k)
promulgated thereunder, upon the written request of an Investor and following delivery to the
Issuer of certificates evidencing the Shares, Additional Shares and/or Warrant Shares held by such
Investor, the Issuer shall, no later than four Trading Days following the delivery by an Investor
to the Issuer or to the Issuer’s transfer agent of a certificate representing Shares, Additional
Shares and/or Warrant Shares with a restrictive legend, direct the transfer agent to remove the
legend described in section 1.3 and, as directed by such Investor, either (a) issue a certificate
evidencing the Shares, Additional Shares and/or Warrant Shares without such legend to such
Investor, or (b) direct an electronic transfer of the Shares, Additional Shares and/or Warrant
Shares via DWAC to a DTC account designated by such Investor; provided, that the Issuer shall pay
any fees of the Issuer’s transfer agent with respect to such certificate issuance or DWAC transfer;
provided further, however, that in the case of a sale pursuant to Rule 144(k), such holder of
Securities shall provide such information as is reasonably requested by the Issuer to ensure that
such Securities may be sold in reliance on Rule 144(k); and provided, further, that in order to
receive shares without a legend, the holder of such Securities shall submit to the company a
representation letter stating that (and thereby agrees that) (i) to the extent the exemption from
prospectus delivery requirements in Rule 172 under the Securities Act is not available, the holder
will comply with the prospectus delivery requirements of the Securities Act and (ii) the holder is
aware that it must suspend sales of the Securities covered by a Registration Statement during a
Suspension Period as provided in Section 6.5 and not recommence such sales until such time as is
provided for in Section 6.5(a).

1.5 LEGAL, TAX OR INVESTMENT ADVICE. Each Investor understands that nothing in this Agreement or
any other materials presented to such Investors in connection with the purchase and sale of the
Units constitutes legal, tax or investment advice. Each Investor has consulted such legal, tax and
investment advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of Units.

ARTICLE 2

CLOSING

2.1 CLOSING. The closing of the transactions contemplated herein (the “CLOSING”) shall take place

Closing shall take place at the offices of Bryan Cave LLP, 1290 Avenue of the Americas, New York,

ARTICLE 3

REPRESENTATIONS AND WARRANTIES OF THE ISSUER

As a material inducement to the Investors entering into this Agreement and subscribing for the
Units, the Issuer represents and warrants to the Investors as follows as of the date hereof:

3.1 CORPORATE STATUS. The Issuer is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has all requisite corporate power and
authority to own and lease its properties and assets and to conduct its business as now conducted
except where the failure to do so would not have a Material Adverse Effect. Each Subsidiary as
referred to in the SEC Reports (as hereinafter defined) is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its incorporation and has all
requisite corporate power and authority to own and lease its properties and assets and to conduct
its business as now conducted except where the failure to do so would not have a Material Adverse
Effect. The Issuer and its Subsidiaries are each qualified to do business as a foreign corporation
and are in good standing in all states where the conduct of their respective businesses or their
ownership or leasing of property requires such qualification, except where the failure to so
qualify would not have a Material Adverse Effect.

3.2 CORPORATE POWER AND AUTHORITY. The Issuer has the corporate power and authority to execute and
deliver this Agreement and the Warrants (collectively, the “TRANSACTION DOCUMENTS”) and to issue
the Securities in accordance with the terms hereof and thereof, and to perform its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. At
the time of the Closing, the Issuer will have taken all necessary corporate action to authorize the
execution, delivery and performance of the Transaction Documents and the consummation of the
transactions contemplated thereby.

3.3 ENFORCEABILITY. Each of the Transaction Documents has been duly executed and delivered by the
Issuer and (assuming it has been duly authorized, executed and delivered by the Investors)
constitutes a legal, valid and binding obligation of the Issuer, enforceable against the Issuer in
accordance with their respective terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting enforcement of
creditors’ rights generally, and (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, and (iii) with respect to the
indemnification provisions set forth herein, as and to the extent limited by public policy.

3.4 NO VIOLATION. The execution and delivery by the Issuer of the Transaction Documents, the
consummation of the transactions contemplated thereby, and the compliance by the Issuer with the
terms and provisions thereof (including, without limitation, the Issuer’s issuance to the Investors
of the Securities as contemplated by and in accordance with this Agreement), will not result in a
default under (or give any other party the right, with the giving of notice or the passage of time
(or both), to declare a default or accelerate any obligation under) or violate any provision of the
Certificate of Incorporation or By-Laws of the Issuer or any material Contract to which the Issuer
is a party (except to the extent such a default, acceleration, or violation would not, in the case
of a Contract, have a Material Adverse Effect on the Issuer), or violate any Requirement of Law
applicable to the Issuer, or result in the creation or imposition of any material Lien upon any of
the capital stock, properties or assets of the Issuer or any of its Subsidiaries (except where such
violations of any Requirement of Law or creations or impositions of any Liens would not have a
Material Adverse Effect on the Issuer).

3.5 CONSENTS/APPROVALS. Except for the filing of a Registration Statement in accordance with
Article 6 hereof, a filing of a Form D with the SEC, the securities commissions of the states in
which the Securities are to be issued, filing of listing applications with respect to the
Registrable Securities with The Nasdaq Stock Market, and the granting of Stockholder Approval as
contemplated by Section 5.11(b), (a) no consents, permits, filings, authorizations or other actions
of any Governmental Authority, and (b) no vote or consent of the Issuer’s stockholders (other than
as contemplated in Section 5.11(b), are required to be obtained or made by the Issuer for the
Issuer’s execution, delivery and performance of this Agreement which have not already been obtained
or made. No consent, approval, waiver or other action by any Person under any Contract to which
the Issuer is a party or by which the Issuer or any of its properties or assets are bound is
required or necessary for the execution, delivery or performance by the Issuer of this Agreement
and the consummation of the transactions contemplated hereby, except where the failure to obtain
such consents would not have a Material Adverse Effect on the Issuer.

3.6 VALID ISSUANCE. Upon payment of the Subscription Amount applicable to an Investor and delivery
to such Investor of the Securities, such Securities will be validly issued, fully paid and
non-assessable, free from all Liens with respect to the issuance of such Securities and will not be
subject to any preemptive or similar rights.

3.7 SEC FILINGS, OTHER FILINGS AND NASDAQ COMPLIANCE. The Issuer has delivered or made accessible
to the Investors all reports required to be filed by it under the Securities Act and the Exchange
Act, including pursuant to Section 13(a) or 15(d) thereof, for the twelve months preceding the date
hereof (the “SEC REPORTS,” and together with the disclosure schedule to this Agreement, the
“DISCLOSURE DOCUMENTS”). Except to the extent set forth in a subsequent amendment thereto, the SEC
Reports, when filed, complied in all material respects with all applicable requirements of the
Exchange Act. None of the SEC Reports, at the time of filing, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading in the light of the circumstances in which they
were made. The Issuer has received notice from The Nasdaq Stock Market that its common stock is
subject to delisting from the Nasdaq Capital Market as a result of failure to comply with the $1.00
per share bid price requirement for 30 consecutive days as required by Nasdaq Marketplace Rule
4310(c)(4). The Issuer has been provided until July 3, 2006, to regain compliance with Nasdaq
minimum bid price requirements. The Issuer has taken, or will have taken prior to July 3, 2006,
all necessary actions to ensure its continued inclusion in, and the continued eligibility of the
Common Stock for trading on, The Nasdaq Capital Stock Market (the “PRINCIPAL MARKET”) under all
currently effective inclusion requirements. Each balance sheet included in the SEC Reports
(including any related notes and schedules) fairly presents in all material respects the
consolidated financial position of the Issuer as of its date, and each of the other financial
statements included in the SEC Reports (including any related notes and Schedules) fairly presents
in all material respects the consolidated results of operations of the Issuer for the periods or as
of the dates therein set forth in accordance with GAAP consistently applied during the periods
involved (except that the interim reports are subject to adjustments which might be required as a
result of year end audit and except as otherwise stated therein).

3.8 GENERAL SOLICITATION; COMMISSIONS. Neither the Issuer, nor any of its affiliates, nor any
Person acting on its or their behalf, has engaged in any form of general solicitation or general
advertising (within the meaning of Regulation D) in connection with the offer or sale of the
Securities. The Issuer shall be responsible for the payment of any placement agent’s fees,
financial advisory fees, or brokers’ commissions (other than for persons engaged by any Investor or
its investment advisor) relating to or arising out of the transactions contemplated hereby. The
Issuer shall pay, and hold each Investor harmless against, any liability, loss or expense
(including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection
with any such claim. Except as described in Schedule 3.8, no brokerage or finder’s fees or
commissions are or will be payable by the Issuer to any broker, financial advisor or consultant,
finder, placement agent, investment banker, bank or other Person with respect to the transactions

on Schedule 3.12 or in the case of a Piggy-Back Registration under Section 6.2(b), which securities
may be included in such Registration Statement.

3.13 OFFERINGS. Subject in part to the truth and accuracy of the Investors’ representations and
warranties set forth in this Agreement, the offer, sale and issuance of the Securities as
contemplated by this Agreement are exempt from the registration requirements of the Securities Act
and any applicable state securities laws, and neither the Issuer nor any authorized agent acting on

without limitation, under the federal and state securities laws, Employee Retirement Income
Security Act of 1974, as amended and all laws relating to the employment of labor), except for such
violations which would not, individually or in the aggregate, have a Material Adverse Effect.

3.15 NASDAQ CAPITAL MARKET. The Common Stock is listed on The Nasdaq Capital Market and, except

SEC or the NASD is contemplating terminating such listing or registration. The issuance of the

form or manner of filing or submission of such certifications. Except as disclosed in the SEC
Reports, the Company is in compliance with any and all applicable requirements of the
Sarbanes-Oxley Act of 2002 and any and all applicable rules and regulations promulgated by the SEC
thereunder, except where such noncompliance would not have, individually or in the aggregate, a
Material Adverse Effect.

3.18 DISCLOSURE. The Issuer is aware of no facts which lead it to believe that the Disclosure
Documents, as of their respective dates, contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

3.19 CONFIDENTIAL INFORMATION. Other than this Agreement and the terms of the transactions
contemplated hereby, the Issuer has not provided any material non-public information to the
Investors in connection with this Agreement or the transactions contemplated hereby. The Issuer
acknowledges that each Investor shall be relying on the foregoing representation in effecting
transactions in securities of the Issuer.

3.20 PATENTS AND TRADEMARKS. To the knowledge of the Issuer and each of its Subsidiaries, the
Issuer and its Subsidiaries have, or have rights to use, all patents, patent applications,
trademarks, trademark applications, service marks, trade names, copyrights, licenses and other
similar rights that are necessary or material for use in connection with their respective
businesses as described in the SEC Reports and which the failure to so have could have or would
reasonably be expected to result in a Material Adverse Effect (collectively, the “INTELLECTUAL
PROPERTY RIGHTS”). Except as described in the SEC Reports or on Schedule 3.20, neither the Issuer
nor any of its Subsidiaries has received a written notice that the Intellectual Property Rights
used by the Issuer or any of its Subsidiaries violates or infringes upon the rights of any Person.
To the knowledge of the Issuer, all such Intellectual Property Rights are enforceable in all
material respects.

3.21 INSURANCE. The Issuer and its Subsidiaries are insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are prudent and customary in
the businesses in which the Issuer and its Subsidiaries are engaged. Neither the Issuer nor any of
its Subsidiaries has any knowledge that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from similar insurers as
may be necessary to continue its business without a significant increase in cost.

3.22 TRANSACTIONS WITH AFFILIATES. Except as described in the SEC Reports or on Schedule 3.22,
none of the officers or directors of the Issuer is presently a party to any transaction with the
Issuer or any of its Subsidiaries (other than for services as officers and directors), including
any contract, agreement or other arrangement providing for the furnishing of services to or by,
providing for rental of real or personal property to or from, or otherwise requiring payments to or
from any officer or director or, to the knowledge of the Issuer, any entity in which any officer or
director has a substantial interest or is an officer, director, trustee or partner, in each case in
excess of $60,000 other than (a) for payment of salary or consulting fees for services rendered,
(b) reimbursement for expenses incurred on behalf of the Issuer and (c) for other employee
benefits, including stock option agreements under any stock option plan of the Issuer.

3.23 NO INTEGRATED OFFERING. Neither the Issuer, nor any of its Affiliates, nor any Person acting
on its or their behalf, has directly or indirectly made any offers or sales of any security or
solicited any offers to buy any security under circumstances that would cause the offering of the
Securities pursuant to this Agreement to be integrated with prior offerings by the Issuer for
purposes of the Securities Act which would prevent the Issuer from selling the Securities pursuant
to Regulation D and Rule 506 thereof under the Securities Act, or any applicable exchange-related
stockholder approval provisions, nor will the Issuer or any of its Affiliates or Subsidiaries take
any action or steps that would cause the offering of the Securities to be integrated with other
offerings if such other offering, if integrated, would cause the offer and sale of the Securities
not to be exempt from registration pursuant to Regulation D and Rule 506 thereof under the
Securities Act.

3.24 PRICE OF COMMON STOCK. The Issuer has not taken, and will not take prior to the Closing,
directly or indirectly, any action designed to cause or result in, or which has constituted or
which might reasonably be expected to constitute, the stabilization or manipulation of the price of
the shares of the Common Stock to facilitate the sale or resale of the Securities.

3.25 SOLVENCY. Based on the financial condition of the Issuer as of the Closing Date (and
assuming that the Closing shall have occurred), (i) the Issuer’s fair saleable value of its assets
exceeds the amount that will be required to be paid on or in respect of the Issuer’s existing debts
and other liabilities (including known contingent liabilities) as they mature; (ii) the Issuer’s
assets do not constitute unreasonably small capital to carry on its business for the current fiscal
year as now conducted and as proposed to be conducted including its capital needs taking into
account the particular capital requirements of the business conducted by the Issuer, and projected
capital requirements and capital availability thereof; and (iii) the current cash flow of the
Issuer, together with the proceeds the Issuer would receive, were it to liquidate all of its
assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all
amounts on or in respect of its debt when such amounts are required to be paid. The Issuer does
not intend to incur debts beyond its ability to pay such debts as they mature (taking into account
the timing and amounts of cash to be payable on or in respect of its debt).

3.26 LABOR RELATIONS. No material labor dispute exists or, to the knowledge of the Company,
is imminent with respect to any of the employees of the Company or any Subsidiary which could
reasonably be expected to result in a Material Adverse Effect.

3.27 FOREIGN CORRUPT PRACTICES ACT. The Issuer has not taken any action which would cause it
to be in violation of the Foreign Corrupt Practices Act of 1977, as amended, or any rules or
regulations thereunder. To the Issuer’s knowledge, there is not now, and there has never been,
any employment by the Issuer of, or beneficial ownership in the Issuer by, any governmental or
political official in any country in the world.

performance, injunctive relief or other equitable remedies, and (iii) with respect to the
indemnification provisions set forth herein, as and to the extent limited by public policy.

4.2 NO VIOLATION. The execution and delivery by such Investor of this Agreement, the consummation
of the transactions contemplated hereby, and the compliance by such Investor with the terms and
provisions hereof, will not result in a default under (or give any other party the right, with the
giving of notice or the passage of time (or both), to declare a default or accelerate any
obligation under) or violate any charter or similar documents of such Investor, if other than a
natural person, or any Contract to which such Investor is a party or by which it or its properties
or assets are bound, or violate any Requirement of Law applicable to such Investor, other than such
violations or defaults which, individually and in the aggregate, do not and will not have a
Material Adverse Effect on such Investor.

4.3 CONSENTS/APPROVALS. No consents, filings, authorizations or actions of any Governmental
Authority are required for such Investor’s execution, delivery and performance of this Agreement.
No consent, approval, waiver or other actions by any Person under any Contract to which such

securities laws), and no one other than such Investor has any beneficial interest in the Securities
(except for those individuals who hold dispositive or voting power over the Securities purchased by

the right to dispose of the Securities at any time in accordance with or pursuant to a registration
statement or an exemption under the Securities Act. Such Investor understands that the offer and
sale by the Issuer of the Securities being acquired by such Investor hereunder has not been
registered under the Securities Act by reason of their contemplated issuance in transactions exempt
from the registration and prospectus delivery requirements of the Securities Act pursuant to
Section 4(2) thereof, and that the reliance of the Issuer on such exemption from registration is
predicated in part on these representations and warranties of such Investor. Such Investor

investment contemplated herein, other than the representations and warranties set forth in Article
3 hereof.

4.9 KNOWLEDGE AND EXPERIENCE. Such Investor has such knowledge and experience in financial, tax
and business matters, including substantial experience in evaluating and investing in common stock
and other securities (including the common stock and other securities of speculative companies), so
as to enable such Investor to utilize the information referred to in Section 4.6 hereof and any
other information made available by the Issuer to such Investor in order to evaluate the merits and
risks of an investment in the Securities and to make an informed investment decision with respect
thereto. Such Investor is able to bear the economic risk of an investment in the Securities and is
able to afford a complete loss of such investment.

4.10 INDEPENDENT DECISION. Such Investor is not relying on the Issuer, any other potential
investor, or on any legal or other opinion in the materials reviewed by such Investor with respect
to the financial or tax considerations of such Investor relating to its investment in the
Securities. Such Investor has relied solely on the representations and warranties, covenants and
agreements of the Issuer in this Agreement (including the Exhibits hereto) and on its examination

acting on behalf of or pursuant to any understanding with such Investor, engaged in any
transactions in the securities of the Issuer (including, without limitations, any Short Sales
involving the Issuer’s securities) since the time that such Investor was first contacted by the
Issuer or Roth Capital Partners, LLC regarding an investment in the Issuer. Such Investor
covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with
it will engage in any transactions in the securities of the Issuer (including Short Sales) prior to

to Section 15 of the Exchange Act.

4.17 INDEPENDENT INVESTMENT. No Investor has agreed to act with any other Investor for the purpose
of acquiring, holding, voting or disposing of the Securities purchased hereunder for purposes of
Section 13(d) under the Exchange Act, and each Investor is acting independently with respect to its
investment in the Securities.

4.18 REGULATION M. Each Investor represents and warrants that it is aware of the following
Telephone Interpretation in the SEC Manual of Publicly Available Telephone Interpretations (July
1997):

A.65. Section 5

An issuer filed a Form S-3 registration statement for a secondary offering of common
stock which is not yet effective. One of the selling shareholders wanted to do a
short sale of common stock “against the box” and cover the short sale with
registered shares after the effective date. The issuer was advised that the short
sale could not be made before the registration statement becomes effective, because
the shares underlying the short sale are deemed to be sold at the time such sale is
made. There would, therefore, be a violation of Section 5 if the shares were
effectively sold prior to the effective date.

In addition, each Investor acknowledges that (i) the Issuer has informed the Investor that the
anti-manipulation provisions of Regulation M under the Exchange Act may apply to purchases and
sales of Shares, Additional Shares and Warrant Shares and that there are restrictions on market
making activities by persons engaged in the distribution of such Securities and (ii) the Issuer has
advised the Investor to consult with its counsel regarding such matters.

ARTICLE 5

COVENANTS

5.1 PUBLIC ANNOUNCEMENTS. Each party to this Agreement agrees that it shall not issue or release
any public announcement with respect to this Agreement or the transactions provided for herein,

governmental or regulatory notifications and filings required to be made by it with or to any
Governmental Authority in connection with the consummation of the transactions contemplated hereby.
The Issuer and each Investor agree to cooperate with the other in the preparation and filing of
all forms, notifications, reports and information, if any, required or reasonably deemed advisable
pursuant to any Requirement of Law or the rules of Nasdaq Stock Market in connection with the

reasonable opinion of such party would result in or produce a Material Adverse Effect on such
party.

an Investor continues to hold any Securities acquired hereunder, such Investor will not, nor will
any Person acting on its behalf or pursuant to any understanding with such Investor, engage in any
Short Sales, except on those days (each a “PERMITTED DAY”) on which the aggregate short position
with respect to the Common Stock of the Investor prior to giving effect to any Short Sales by the
Investor on such Permitted Day does not exceed such Investor’s Permitted Share Position (as defined
below) on such Permitted Day; provided, however, that such Investor will only be entitled to engage
in transactions that constitute Short Sales on a Permitted Day to the extent that following such
transaction, the aggregate short position with respect to the Common Stock of the Investor does not
exceed such Investor’s Permitted Share Position. For purposes of Section 5.4, the Investor’s
“PERMITTED SHARE POSITION” means, with respect to any date of determination, the number of shares
of Common Stock owned by the Investor (including Shares, Additional Shares, Warrant Shares and any
Warrant Shares underlying unexercised Warrants).

(b) Other Transactions Permitted. Subject to Section 5.4(a) and applicable securities laws,

with the offer or sale of the Securities for purposes of the rules and regulations of the Nasdaq
Capital Market such that the transaction contemplated hereby would violate any such rules or
regulations.

5.7 USE OF PROCEEDS. The Issuer shall use the net proceeds from the sale of the Units hereunder
for working capital and any other general corporate purposes.

5.8 DISCLOSURE OF MATERIAL INFORMATION. The Issuer covenants and agrees that neither it nor, to

its agents or counsel with any information that the Issuer believes constitutes material non-public
information, unless prior thereto such Investor shall have executed a written agreement regarding
the confidentiality and use of such information. The Issuer understands and confirms that each
Investor shall be relying on the foregoing representations in effecting transactions in securities
of the Issuer. Notwithstanding the foregoing, the Issuer’s compliance with the terms of Section
5.11 (including the notice provisions thereof) of that certain Subscription Agreement, dated
December 21, 2004, by and among the Issuer and the investors listed on Annex I thereto shall not
under any circumstances constitute a breach of this Section 5.8.

upon each national securities exchange and automated quotation system, if any, upon which the
Common Stock is then listed (subject to official notice of issuance) and shall maintain such
listing of all Registrable Securities from time to time issuable under the terms of the Transaction
Documents. The Issuer has taken, or will have taken prior to July 3, 2006, all commercially
reasonable necessary actions to ensure its continued inclusion in, and the continued eligibility of
the Common Stock for trading on, the Principal Market and shall take all commercially reasonable
necessary actions to maintain such inclusion and eligibility until such time as all Registrable
Securities have been sold or transferred; provided, that the foregoing shall not preclude the
Issuer from changing its listing to the Nasdaq National Market, the New York Stock Exchange or

(a) make and keep public information available, as those terms are understood and defined in
Rule 144;

(b) file with the SEC in a timely manner all reports and other documents required of the

upon request, (i) a written statement by the Issuer, if true, that it has complied with the
reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the
most recent annual report of the Issuer and such other reports and documents so filed by the
Issuer, and (iii) such other information as may be reasonably requested to permit the Investors to

Period, have the option to either:

(i) Pay to each Investor an amount in cash (the “RESET AMOUNT”), which must be received by
such Investor no later than the 10th Business Day following the Reset Period, equal to
the lesser of (A) the Threshold Price minus the Reset Price, multiplied by the number of Shares
then held by such Investor on the Trading Day immediately following the Reset Period, or (B) the
Per Unit Purchase Price minus the Reset Price, multiplied by the number of Shares then held by such
Investor on the Trading Day immediately following the Reset Period. The Issuer agrees that all
such payments (x) will be made free of any and all set-offs and claims that it may have against any
Investor and (y) will be made in U.S. dollars by wire transfer of immediately available funds to
the account designated by each Investor for such purpose; or

(ii) Issue to each Investor such number of additional shares of Common Stock (collectively,
“ADDITIONAL SHARES”), which must be received by such Investor no later than the 10th
Business Day following the Reset Period, equal to such Investor’s Reset Amount divided by the Reset
Price.

(b) The Issuer covenants and agrees that, solely as a condition precedent to the issuance of
the Additional Shares to Investors in accordance with Section 5.11(a)(ii), the Issuer must first
obtain the approval of its stockholders, if required, for purposes of complying with Nasdaq Rule
4350(i) (the “STOCKHOLDER APPROVAL”).

In furtherance of the obligations of the Issuer under this Section 5.11(b), as a condition
precedent to the issuance of the Additional Shares to Investors in accordance with Section
5.11(a)(ii), (1) the Board of Directors of the Issuer shall adopt proper resolutions authorizing
the issuance of the Additional Shares, (2) the Board of Directors of the Issuer shall recommend and
the Issuer shall otherwise promptly and duly obtain the Stockholder Approval, including, without
limitation, soliciting proxies from its stockholders in connection therewith and having all
management-appointed proxy-holders vote their proxies in favor of such proposals to carry out such
resolutions (and hold a meeting of the stockholders as soon as practicable, but in any event not
later than the 60th day after delivery of the proxy or other applicable materials
relating to such meeting) and (3) within three Business Days of obtaining such stockholder
authorization, take all actions necessary to effectuate the Stockholder Approval.

(c) Each Investor covenants that, as a condition precedent to its right to receive any cash or
securities pursuant to this Section 5.11, neither it nor any Person acting on its behalf or
pursuant to any understanding with it will engage in or close out any transactions in the
securities of the Issuer (including Short Sales) during the Reset Period.

(d) The aggregate Reset Amount payable to an Investor under Section 5.11(a)(i) or the
aggregate value of Additional Shares payable to an Investor under Section 5.11(a)(ii) shall not
exceed ten percent (10%) of the aggregate purchase price of the Units purchased by such Investor
pursuant to this Agreement.

(e) It shall be a condition precedent to any issuance of Additional Shares pursuant to Section
5.11(a)(ii) that (i) the Issuer shall be eligible for continued inclusion in, and the Common Stock
shall be eligible for trading on, the Principal Market or another principal stock exchange or
market under all then effective inclusion requirements, and (ii) the Issuer shall not be in
material breach of the Transaction Documents.

5.12 RESERVATION OF COMMON STOCK. As of the Closing Date, the Issuer shall have reserved and
the Issuer shall continue to reserve and keep available at all times, free of preemptive rights, a
sufficient number of shares of Common Stock for the purpose of enabling the Issuer to issue Shares
pursuant to this Agreement and to issue Warrant Shares pursuant to the Warrants.

5.13 ADDITIONAL ISSUANCES OF SECURITIES. The provisions of this Section 5.13 shall not be
effective if it is determined under the rules of the Principal Market (or any other principal stock
exchange or market (including the Nasdaq National Market) on which the Issuer’s shares of Common
Stock may become listed) that such provisions would result in the Issuer being required to obtain
the approval of its stockholders for the consummation of the transactions contemplated by this
Agreement.

(a) For purposes of this Section 5.13, the following definitions shall apply:

(i) “APPROVED STOCK PLAN” means any plan which has been approved by the board of directors of
the Issuer, pursuant to which the Issuer’s securities may be issued to any consultant, employee,
officer or director for services provided to the Issuer.

(ii) “CONVERTIBLE SECURITIES” means any stock or securities (other than Options) convertible
into or exercisable or exchangeable for shares of Common Stock.

(ii) “OPTIONS” means any rights, warrants or options to subscribe for or purchase shares of
Common Stock or Convertible Securities.

(ii) “COMMON STOCK EQUIVALENTS” means, collectively, Options and Convertible Securities.

(b) From the date hereof until the one year anniversary of the Closing Date (the “TRIGGER
DATE”), except as provided in clauses (vii) and (viii) of this Section 5.13(b), the Issuer will
not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or
announce any offer, sale, grant or any option to purchase or other disposition of) any of its
equity or equity equivalent securities, including without limitation any debt, preferred stock or
other instrument or security that is, at any time during its life and under any circumstances,
convertible into or exchangeable or exercisable for shares of Common Stock or Common Stock
Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a
“SUBSEQUENT PLACEMENT”) unless the Issuer shall have first complied with this Section 5.13(b).

(i) The Issuer shall deliver to each Investor an electronic or written notice (the ”OFFER
NOTICE”) of any proposed or intended issuance or sale or exchange (the ”OFFER”) of the securities
being offered (the “OFFERED SECURITIES”) in a Subsequent Placement, which Offer Notice shall (A)
identify and describe the Offered Securities, (B) describe the price (which may be expressed as a
percentage of the market price on the date definitive agreements are to be executed) and other
material terms upon which they are to be issued, sold or exchanged, and the approximate number or
amount of the Offered Securities to be issued, sold or exchanged, (C) identify the persons or
entities (if known) to which or with which the Offered Securities are to be offered, issued, sold
or exchanged and (D) offer to issue and sell to or exchange with such Investors a pro rata portion
of 30% of the Offered Securities, allocated among such Investors (x) based on such Investor’s pro
rata portion of the aggregate number of Shares purchased hereunder (the “BASIC AMOUNT”), and (y)
with respect to each Investor that elects to purchase its Basic Amount, any additional portion of
the Offered Securities attributable to the Basic Amounts of other Investors as such Investor shall
indicate it will purchase or acquire should the other Investors subscribe for less than their Basic
Amounts (the “UNDERSUBSCRIPTION AMOUNT”). In the event the material terms of the Subsequent
Placement change prior to execution of definitive agreements with respect thereto, the Issuer shall
notify the Investor of such modified terms and the Offer Notice shall be deemed modified thereby
(and, in the event an Investor has elected to accept the Offer, such Investor may elect to revoke
such acceptance by notifying the Issuer in writing of such revocation within one day after the
Issuer delivers such notice).

(ii) To accept an Offer, in whole or in part, such Investor must deliver a written notice to
the Issuer prior to the end of the fifth (5th) Business Day after such Investor’s
receipt of the Offer Notice or such shorter period (which shall not be less than one Business Day)
as the Issuer shall specify in the Offer Notice (the “OFFER PERIOD”), setting forth the portion of
such Investor’s Basic Amount that such Investor elects to purchase and, if such Investor shall
elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Investor
elects to purchase (in either case, the “NOTICE OF ACCEPTANCE”). If the Basic Amounts subscribed
for by all Investors are less than the total of all of the Basic Amounts, then each Investor who
has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to
purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has
subscribed for; provided, however, that if the Undersubscription Amounts subscribed
for exceed the difference between the total of all the Basic Amounts and the Basic Amounts
subscribed for (the “AVAILABLE UNDERSUBSCRIPTION AMOUNT”), each Investor who has subscribed for any
Undersubscription Amount shall be entitled to purchase only that portion of the Available
Undersubscription Amount as the Basic Amount of such Investor bears to the total Basic Amounts of
all Investors that have subscribed for Undersubscription Amounts, subject to rounding by the Issuer
to the extent its deems reasonably necessary.

(iii) The Issuer shall have thirty (30) Business Days from the expiration of the Offer Period
above to offer, issue, sell or exchange all or any part of such Offered Securities as to which a
Notice of Acceptance has not been given by the Investors (the “REFUSED SECURITIES”) (it being
understood that Refused Securities include 70% of the Offered Securities not covered by the Offer
Notice and any remaining Offered Securities as to which a Notice of Acceptance has not been given
by the Investors), and only upon terms and conditions (including, without limitation, unit prices
and interest rates) that are not more favorable to the acquiring person or persons or less
favorable to the Issuer than those set forth in the Offer Notice (as such notice may be modified
pursuant to clause (i) above).

(iv) In the event the Issuer shall propose to sell less than all the Refused Securities (any
such sale to be in the manner and on the terms specified in Section 5.13(b)(iii) above), then each
Investor may, at its sole option and in its sole discretion, reduce the number or amount of the
Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than
the number or amount of the Offered Securities that such Investor elected to purchase pursuant to
Section 5.13(b)(ii) above multiplied by a fraction, (A) the numerator of which shall be the number
or amount of Offered Securities the Issuer actually proposes to issue, sell or exchange (including
Offered Securities to be issued or sold to Investors pursuant to Section 5.13(b)(iii) above prior
to such reduction) and (B) the denominator of which shall be the original amount of the Offered
Securities. In the event that any Investor so elects to reduce the number or amount of Offered
Securities specified in its Notice of Acceptance, the Issuer may not issue, sell or exchange more
than the reduced number or amount of the Offered Securities unless and until such securities have
again been offered to the Investors in accordance with Section 5.13(b)(i) above.

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused
Securities, the Investors shall acquire from the Issuer, and the Issuer shall issue to the
Investors, the number or amount of Offered Securities specified in the Notices of Acceptance, as
reduced pursuant to Section 5.13(b)(iii) above if the Investors have so elected, upon the terms and
conditions specified in the Offer. The purchase by the Investors of any Offered Securities is
subject in all cases to the preparation, execution and delivery by the Issuer and the Investors of
a purchase agreement relating to such Offered Securities reasonably satisfactory in form and
substance to the Investors and their respective counsel. It is expressly agreed that the Issuer
shall not be required to issue, sell or exchange all or any portion of the Refused Securities and
if the Purchaser abandons any such issuance, sale or exchange then Investors will not have the
right to purchase any Offered Securities hereunder notwithstanding the delivery of a Notice of
Acceptance hereunder.

(vi) Any Offered Securities not acquired by the Investors or other persons in accordance with
Section 5.13(b)(iii) above may not be issued, sold or exchanged until they are again offered to the
Investors under the procedures specified in this Agreement.

(vii) The provisions of this Section 5.13 shall not apply in connection with the issuance of
any Common Stock or Common Stock Equivalents issued or issuable: (A) in connection with any
Approved Stock Plan; (B) to officers, directors, employees or consultants, whether or not pursuant
to an Approved Stock Plan, primarily for compensatory purposes with respect to services rendered or
to be rendered or as an inducement grant to any such individuals as permitted under applicable
Nasdaq Stock Market Rules, (C) upon exercise of the Warrants; (D) pursuant to any public offering
of the Company’s equity or debt securities; (E) in connection with a change of control or
acquisition transaction (including by way of a merger, consolidation, tender offer, asset
acquisition or otherwise) approved by the Company’s board of directors; (F) to customers, vendors,
licensors or joint venture partners or in connection with other strategic alliances, the primary
purpose of which is not to raise equity capital; (G) to any strategic investor (whether or not a
primary purpose of such issuance is to raise equity capital); (H) in connection with an equipment
lease financing transaction or a credit financing transaction, the primary purpose of which is not
to raise equity capital; (I) in connection with a dividend, distribution or issuance of Convertible
Securities pursuant to a stockholder rights plan (poison pill) approved by the Company’s board of
directors; (J) in any other transaction the primary purpose of which is not to raise equity capital
and (K) upon conversion of any Options or Convertible Securities which are outstanding on the day
immediately preceding the date hereof or that may be issued pursuant to any of clauses (A) through
(J) of this clause (vii) (the actions referred to in subclauses (A) through (K) collectively
referred to as “EXEMPT TRANSACTIONS.”)

(viii) The provisions of this Section 5.13 shall not apply in connection with the issuance of
any Common Stock issued or issuable in connection with any bona fide financing if the participation
of Investors in such financing (assuming Investors exercised their rights to so participate
pursuant to this Section 5.13) would cause the offering of the securities in connection with such
bona fide financing to be integrated with the issuance of the Securities for purposes of any rules
of the Principal Market (or any other national securities exchange (including the Nasdaq National
Market) on which the Issuer’s shares of Common Stock may become listed) or otherwise result in the
Issuer being required to obtain the approval of its stockholders for all or any portion of such
bona fide financing under the rules of the Principal Market (or any other national securities
exchange (including the Nasdaq National Market) on which the Issuer’s shares of Common Stock may
become listed), in which case, the Issuer shall notify the Investors of such potential integration
and the basis therefor; provided that at the request of one or more Investors that desire(s) to
exercise its rights under this Section 5.13 with respect to such financing, the Issuer shall use
commercially reasonable best efforts to cooperate with such Investors to explore whether the
transaction can be structured in a manner that would not result in such integration or stockholder
approval requirement, including by participating in discussions with the staff of the Principal
Market (it being understood that the Issuer shall not be required to alter the structure of such
transaction in a manner that would be adverse to it in any material respect).

5.14 NO ISSUANCES UNTIL AFTER EFFECTIVNESS. Except for any Exempt Transaction or any issuance
of securities to be registered on a Special Registration Statement, the Issuer shall not, prior to
the earlier of (a) the 60-day anniversary of the effectiveness date of the initial Registration
Statement required to be filed pursuant to Section 6.2 hereof, or (b) the sixth month anniversary
of the Closing Date, consummate a Subsequent Placement.

ARTICLE 6

REGISTRATION RIGHTS

The Investors shall have the following registration rights with respect to the Registrable
Securities owned by it:

6.1 TRANSFER OF REGISTRATION RIGHTS. Subject to the provisions of this Agreement, each Investor
may assign the registration rights with respect to the Registrable Securities to any party or
parties to which it may from time to time transfer the Registrable Securities, provided that the
transferee agrees in writing with the Issuer to be bound by the applicable provisions of this
Agreement regarding such registration rights and indemnification relating thereto. Upon assignment
of any registration rights pursuant to this Section 6.1 by an Investor, such Investor shall deliver
to the Issuer a notice of such assignment which includes the identity and address of any assignee
and such other information reasonably requested by the Issuer in connection with effecting any such
registration (collectively, the Investor and each such subsequent holder is referred to as a
“HOLDER”). Notwithstanding anything to the contrary herein, the rights of a Holder pursuant to
Article 6 may be assigned only to a transferee or assignee of any Registrable Securities if such
transferee or assignee acquires at least 100,000 shares of such Holder’s Registrable Securities
(equitably adjusted for any stock splits, subdivisions, stock dividends, changes, combinations or
the like) or less if the shares being transferred constitute all of such transferring Holder’s
Registrable Securities.

6.2 REQUIRED REGISTRATION. (a) The Issuer shall use best efforts to file a Registration Statement
on Form S-3, except if the Issuer is not then eligible to register for resale the Registrable
Securities on Form S-3, in which case the Registration Statement shall be on another appropriate
form in accordance herewith, on or before each Filing Date, as the case may be, pursuant to which
the Registrable Securities shall be registered for resale. The Issuer shall use commercially
reasonable efforts to cause the SEC to declare a Registration Statement effective as soon as
practicable after filing, but in any event, no later than its Effectiveness Date, and to thereafter
maintain the effectiveness of such Registration Statement until the earlier of (i) the second
anniversary of the Closing Date, (ii) in the case of a Registration Statement (other than an
initial Registration Statement) which shall include any Additional Shares, the second anniversary
of the date on which the Issuer first has the obligation to issue Additional Shares, or (iii) such
time as all Holders have sold all of their Registrable Securities (the “EFFECTIVENESS PERIOD”).
The Issuer covenants that it will provide written notice to the Investors that each of the Issuer’s
Registration Statements on Form S-3 registering the Registrable Securities has been declared
effective by the SEC, which notice shall be given promptly after the Issuer has received notice of
such effectiveness from the SEC. The Issuer shall file with the SEC in accordance with Rule 424
under the Securities Act the final prospectus to be used in connection with sales pursuant to such
Registration Statement (whether or not such filing is technically required under such Rule), no
later than 5:00 p.m. (New York City time) on the date that such Registration Statement is declared
effective in the event the SEC notifies the Issuer of such effectiveness by 12:00 p.m. on such
date, or no later than 8:00 a.m. (New York City time) on the Business Day after the date such
Registration Statement is declared effective in the event the SEC notifies the Issuer of such
effectiveness after 12:00 p.m. on such date. In the event the Issuer shall not be eligible to file
a registration statement on Form S-3, the Issuer covenants and agrees to undertake to register the
Registrable Securities on Form S-3 as soon as reasonably practicable after the Issuer becomes
eligible to use such form (but shall maintain the effectiveness of a Registration Statement on any
substitute form until such Form S-3 is effective). In the event that (A) a Registration Statement
required hereunder is not declared effective by the applicable Effectiveness Date, and (B) after
such Effectiveness Date the Issuer files any registration statement under the Securities Act for
purposes of a public offering of securities of the Issuer (including, but not limited to,
registration statements relating to secondary offerings of securities of the Company, but excluding
Special Registration Statements), then the Issuer will, subject to customary underwriter cut-backs
and exclusions, include in such registration statement the Registrable Securities then held by such
Investor in such registration statement (any such registration a “PIGGY-BACK REGISTRATION”).

(b) In connection with Section 6.2(a) and for the avoidance of any doubt, if Additional Shares
are issued prior to the filing of the initial Registration Statement, such Additional Shares shall
be included in such initial Registration Statement. If Additional Shares are issued subsequent to
the filing of the initial Registration Statement, then the Issuer shall prepare and file by the
Filing Date for such Registration Statement, an additional Registration Statement covering the
resale of all Registrable Securities not already covered by an existing and effective Registration
Statement, on Form S-3 (except if the Company is not then eligible to register for resale the
Registrable Securities on Form S-3, in which case such registration shall be on another appropriate
form for such purpose).

(c) If: (i) a Registration Statement is not filed on or prior to its Filing Date, or (ii) a
Registration Statement is not declared effective by the SEC on or prior to its required
Effectiveness Date, or (iii) after the Effectiveness Date, such Registration Statement ceases to be
effective and available to the Holders as to all Registrable Securities to which it is required to
cover at any time prior to the expiration of its Effectiveness Period, (any such failure or breach
being referred to as an “EVENT,” and for purposes of clauses (i), (ii) or (iii) the date on which
such Event occurs, being referred to as “EVENT DATE”), then, in addition to any other rights
available to the Holders, on each such Event Date and on each monthly anniversary of each such
Event Date (if the applicable Event shall not have been cured by such date) until the applicable
Event is cured, but subject to Section 6.5(b), the Issuer shall pay to each Holder, as liquidated
damages and not as a penalty, in the case of the initial Registration Statement, a cash payment
equal to 1% of the aggregate purchase price paid by such Investor to the Issuer with respect to the
Shares or Warrant Shares then held by such Holder, and in the case of a Registration Statement with
respect to Additional Shares not included in the initial Registration Statement, a cash payment
equal to 1% of the product of the Reset Price multiplied by the number of Additional Shares then
held by such Holder. The parties agree that the Issuer will not be liable for liquidated damages
under this Section in respect of the Warrants. The liquidated damages pursuant to the terms hereof
shall apply on a pro rata basis for any portion of a month prior to the cure of an Event; provided
that the maximum aggregate liquidated damages payable to a Holder under this Section 6.2(c) shall
not exceed eight percent (8%) of the aggregate purchase price of the Units purchased by such Holder
pursuant to this Agreement. The parties agree that such liquidated damages shall not be the
exclusive damages under this Agreement with respect to the occurrence of such Event.

6.3 REGISTRATION PROCEDURES. (a) In case of a Registration Statement effected by the Issuer
subject to this Article 6, the Issuer shall keep the Holders, advised in writing as to the
initiation of such registration, and as to the completion thereof. In addition, subject to Section
6.2 above, the Issuer shall, to the extent applicable to a Registration Statement:

(i) prepare and file with the SEC such amendments and supplements to a Registration Statement
as may be necessary to keep such registration, effective and comply with provisions of the
Securities Act with respect to the disposition of all securities covered thereby during the period
referred to in Section 6.2(a);

(ii) update, correct, amend and supplement a Registration Statement as necessary;

(iii) notify the Holders when a Registration Statement is declared effective by the SEC, and
furnish such number of prospectuses, including preliminary prospectuses, and other documents
incident thereto as the Holders may reasonably request from time to time;

(iv) use its reasonable best efforts to register or qualify such Registrable Securities under
such other securities or blue sky laws of such jurisdictions of the United States as the Holders
may reasonably request where an exemption is not available to enable it to consummate the
disposition in such jurisdiction of the Registrable Securities (provided that the Issuer will not
be required to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this provision, or (ii) consent to general service of
process in any such jurisdiction, or (iii) subject itself to taxation in any jurisdiction where it
is not already subject to taxation);

(v) notify the Holders at any time when a prospectus relating to the 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 a Registration Statement contains an untrue statement of a
material fact or omits any fact necessary to make the statements therein not misleading, and the
Issuer will prepare a supplement or amendment to such prospectus, so that, as thereafter delivered
to purchasers of such shares, such prospectus will not contain any untrue statements of a material
fact or omit to state any fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

(vi) cause all such Registrable Securities to be listed on each securities exchange on which
similar securities issued by the Issuer are then listed and obtain all necessary approvals from The
Nasdaq Capital Market for trading thereon;

(vii) provide a transfer agent and registrar for all such Registrable Securities not later
than the effective date of a Registration Statement; and

(viii) upon the sale of any Registrable Securities pursuant to a Registration Statement,
direct the transfer agent to remove all restrictive legends from all certificates or other
instruments evidencing the Registrable Securities.

(b) Notwithstanding anything stated or implied to the contrary in Section 6.3(a) above, the
Issuer shall not be required to consent to any underwritten offering of the Registrable Securities
or to any specific underwriter participating in any underwritten public offering of the Registrable
Securities.

(c) Each Holder agrees that upon receipt of any notice from the Issuer of the happening of any
event of the kind described in Section 6.3(a)(v), such Holder will forthwith discontinue such
Holder’s disposition of Registrable Securities pursuant to a Registration Statement relating to
such Registrable Securities until such Holder’s receipt of the copies of the supplemented or
amended prospectus contemplated by Section 6.3(a)(v) and, if so directed by the Issuer, will
deliver to the Issuer at the Issuer’s expense all copies, other than permanent file copies, then in
such Holder’s possession, of the prospectus relating to such Registrable Securities current at the
time of receipt of such notice.

(d) Except as required by law, all expenses incurred by the Issuer in complying with this
Article 6, including but not limited to, all registration, qualification and filing fees, printing
expenses, fees and disbursements of counsel and accountants for the Issuer, blue sky fees and
expenses (including fees and disbursements of counsel related to all blue sky matters)
(“REGISTRATION EXPENSES”) incurred in connection with any registration, qualification or compliance
pursuant to this Article 6 shall be borne by the Issuer. All underwriting discounts and selling
commissions applicable to a sale incurred in connection with any registration of Registrable
Securities and the legal fees and other expenses of a Holder shall be borne by such Holder.

6.4 FURTHER INFORMATION. If Registrable Securities owned by a Holder are included in any
registration, such Holder shall furnish the Issuer such information regarding itself as the Issuer
may reasonably request and as shall be required in connection with any registration (or amendment
or supplement thereto), referred to in this Agreement, and Holder shall indemnify the Issuer with
respect thereto in accordance with Article 7 hereof. Each Investor hereby represents and warrants
to the Issuer, severally and not jointly, that it has accurately and completely provided all
material requested information and answered the questions numbered (a) through (d) on the signature
pages of this Agreement, and such Investor agrees and acknowledges that the Issuer may rely on such
information as being materially true and correct for purposes of preparing and filing a
Registration Statement at the time of filing thereof and at the time it is declared effective,
unless such Investor has notified the Issuer in writing to the contrary prior to such time.

6.5 RIGHT OF SUSPENSION. (a) Notwithstanding any other provision of this Agreement or any related
agreement to the contrary, if any, the Issuer shall have the right, at any time, to suspend the
effectiveness of a Registration Statement and offers and sales of the Registrable Securities
covered thereby whenever, in the good faith judgment of the Issuer, (i) continuing such
effectiveness or permitting such offers and sales could reasonably be expected to have an adverse
effect upon a proposed sale of all or substantially all of the assets of the Issuer or a merger,
acquisition, reorganization, recapitalization or similar current transaction materially affecting
the capital structure or equity ownership of the Issuer, (ii) there exists a material development
or a potential material development with respect to or involving the Issuer that the Issuer would
be obligated to disclose in the prospectus used in connection with a Registration Statement, which
disclosure, in the good faith judgment of the Issuer, after considering the advice of counsel,
would be premature or otherwise inadvisable at such time, or (iii) the SEC has issued a stop order
suspending the effectiveness of a Registration Statement, an event occurs that makes the financial
statements included in a Registration Statement ineligible for inclusion therein or a Registration
Statement or related prospectus or any document incorporated or deemed to be incorporated therein
by reference contains 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, in light of the
circumstances, not misleading (a “SUSPENSION EVENT”). In the event that the Issuer shall determine
to so suspend the effectiveness of a Registration Statement and offers and sales of the Registrable
Securities covered thereby, the Issuer shall, in addition to performing those acts required to be
performed under the Securities Act and/or the Exchange Act or deemed advisable by the Issuer,
deliver to each Holder written notice thereof, signed by the Chief Financial Officer or Chief
Executive Officer of the Issuer. Upon receipt of such notice, the Holders shall discontinue
disposition of the Registrable Securities covered by a Registration Statement and prospectus until
such Holders (x) are advised in writing by the Issuer that the use of a Registration Statement and
prospectus (and offers and sales thereunder) may be resumed, (y) have received copies of a
supplemental or amended prospectus, if applicable, and (z) have received copies of any additional
or supplemental filings which are incorporated or deemed to be incorporated by reference into such
prospectus. The Issuer will exercise commercially reasonable efforts to ensure that the use of a
Registration Statement and prospectus may be resumed as quickly as practicable, provided, however,
that in the event of a Suspension Event, the Issuer’s obligation under Section 6.2 to maintain the
effectiveness of a Registration Statement until the expiration of the Effectiveness Period shall be
extended on a day-for-day basis equal to the amount of time that such Registration Statement shall
have been suspended.

(b) The Issuer’s right to suspend the effectiveness of a Registration Statement and the offers
and sales of the Registrable Securities covered thereby, as described above, shall be for a period
of time (the “SUSPENSION PERIOD”) beginning on the date of the occurrence of the Suspension Event
and expiring on the earlier to occur of (i) the date on which the Suspension Event ceases, or (ii)
thirty (30) days after the occurrence of the Suspension Event; provided, however, that in the event
the Suspension Event relates to a previously undisclosed proposed or pending material business
transaction, the disclosure of which the Issuer determines in good faith would be reasonably likely
to impede the Issuer’s ability to consummate such transaction, the Issuer may extend the Suspension
Period from 30 days to 45 days; provided, however, that any Suspension Periods shall not, in the
aggregate, exceed 60 days in any 12 month period. Notwithstanding the provisions of Section 6.2(c)
and except with respect to an extension of a Suspension Period contemplated in the following
sentence, the Issuer shall not be obligated to pay liquidated damages for the first thirty (30)
days of any such Suspension Period in which the effectiveness of a Registration Statement has been
suspended in accordance with this Section 6.5. In addition, notwithstanding the foregoing, a
Suspension Period may be extended beyond the periods contemplated by this Section 6.5(b) if the
Suspension Event is a Suspension Event described in clause (iii) of Section 6.5(a) (subject to the
Issuer’s obligation to pay liquidated damages with respect to such extension pursuant to Section
6.2(c)).

ARTICLE 7

INDEMNIFICATION

7.1 INDEMNIFICATION RELATING TO REGISTRATION RIGHTS. (a) Subject to Section 7.3, with respect to
any registration, effected or to be effected pursuant to Article 6 of this Agreement, the Issuer
shall indemnify each Holder of Registrable Securities whose securities are included in a
Registration Statement, each of such Holder’s directors and officers, each underwriter (as defined
in the Securities Act) of the securities sold by such Holder (if any), and each Person who controls
(within the meaning of the Securities Act) any such Holder or underwriter (a “CONTROLLING PERSON”)
from and against all losses, damages, liabilities, claims, charges, actions, proceedings, demands,
judgments, settlement costs and expenses (including, without limitation, reasonable attorneys’ fees
and expenses) or deficiencies (collectively, “LOSSES”) of any such Holder or any such underwriter
or Controlling Person if any of the foregoing arise out of:

(i) any untrue statement (or alleged untrue statement) of a material fact contained in any
prospectus or supplement or amendment thereto (including any related registration statement)
incident to any such registration; or

(ii) any omission (or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statement therein, in the light of the circumstances under which
it was made, not misleading,

in each case, relating to any action or inaction required of the Issuer in connection with any such
registration, and will reimburse as incurred each such Person entitled to indemnity under this
Section 7.1 for all legal and other expenses reasonably incurred in connection with investigating
or defending any such Losses; provided, however, that, the foregoing indemnity and reimbursement
obligation shall not be applicable to the extent (and solely to the extent) that any such matter
arises out of or is based on (A) any untrue statement (or alleged untrue statement) or omission (or
alleged omission) made in reliance upon and in conformity with written information furnished to the
Issuer by or on behalf of such Holder or by or on behalf of such an underwriter specifically for
use in such prospectus or supplement or amendment thereto, or (B) the failure of the Holder to
comply with its obligations to discontinue disposition of Registrable Securities during the
suspension of a Registration Statement as set forth in Section 6.5(a) after due notice thereof by
the Issuer.

(b) Subject to Section 7.3, with respect to any registration, qualification or compliance
effected or to be effected pursuant to this Agreement, each Holder of Registrable Securities whose
securities are included in a Registration Statement, shall, severally and not jointly, indemnify
the Issuer or any Controlling Person, and the directors and officers of the Issuer or any
Controlling Person, from and against all Losses of the Issuer if any of the foregoing arise out of:

(i) any untrue statement (or alleged untrue statement) of a material fact contained in any
prospectus or supplement or amendment thereto (including any related Registration Statement,
notification or the like) incident to any such registration, qualification or compliance; or

(ii) any omission (or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statement therein, in the light of the circumstances under which
it was made, not misleading; or

in each case, relating to any action or inaction required of such Holder in connection with any
such registration, qualification or compliance, and will reimburse the Issuer for all legal and
other expenses reasonably incurred in connection with investigating or defending any such Losses;
provided, however, that, the foregoing indemnity and reimbursement obligation shall only be
applicable to the extent (and solely to the extent) that any such matter arises out of or is based
on any untrue statement (or alleged untrue statement) or omission (or alleged omission) made in
reliance upon and in conformity with written information furnished to the Issuer by or on behalf of
the Holder specifically for use in such prospectus, offering circular or other document; provided,
however, that, the obligation of the Holder hereunder shall be limited to an amount equal to the
net proceeds to the Holder of Registrable Securities sold as contemplated hereunder.

7.2 INDEMNIFICATION WITH RESPECT TO STOCKHOLDER SUIT. Subject to Section 7.3, the Issuer
shall indemnify each Investor and each Controlling Person of such Investor from and against all
Losses of any such Investor or Controlling Person if any of the foregoing arise solely as a result
of the issuance by the Issuer of the Securities pursuant to this Agreement, and will reimburse the
Issuer for all legal and other expenses reasonably incurred in connection with investigating or
defending any such Losses; provided, however, that the foregoing indemnity shall not apply to
Losses arising out of or relating to (i) a violation by an Investor of applicable securities laws,
(ii) a breach by an Investor of its representations and warranties contained in this Agreement or
(iii) sales, pledges, margin sales and similar transactions by such Investor to or with any other
stockholders of the Issuer.

7.3 INDEMNIFICATION PROCEDURES. Each Person entitled to indemnification under this Section (an
“INDEMNIFIED PARTY”) shall give notice as promptly as reasonably practicable to each party required
to provide indemnification under this Section (an “Indemnifying Party”) of any action commenced
against or by it in respect of which indemnity may be sought hereunder, but failure to so notify an
Indemnifying Party shall not relieve such Indemnifying Party from any liability that it may have
otherwise than on account of this indemnity agreement so long as such failure shall not have
materially prejudiced the position of the Indemnifying Party. Upon such notification, the
Indemnifying Party shall assume the defense of such action if it is a claim brought by a third
party, if and after such assumption the Indemnified Party shall not be entitled to reimbursement of
any expenses incurred by it in connection with such action except as described below. In any such
action, any Indemnified Party shall have the right to retain its own counsel, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnifying Party and the Indemnified Party shall have mutually agreed to the contrary or (ii) the
named parties in any such action (including any impleaded parties) include both the Indemnifying
Party and the Indemnified Party and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing or conflicting interests between them. The
Indemnifying Party shall not be liable for any settlement of any proceeding effected without its
written consent (which shall not be unreasonably withheld or delayed by such Indemnifying Party),
but if settled with such consent or if there be final judgment for the plaintiff, the Indemnifying
Party shall indemnify the Indemnified Party from and against any loss, damage or liability by
reason of such settlement or judgment.

9.11 HEADINGS. The headings contained in this Agreement are for convenience of reference only and

concerning the interpretations, enforcement and defense of the transactions contemplated by this

directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state
and federal courts sitting in the City of New York. Each party hereto hereby irrevocably submits
to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, New
York for the adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein (including with respect to the enforcement of

enforce any provisions of this Agreement or the Warrants, then the prevailing party in such action
or proceeding shall be reimbursed by the other party for its attorneys fees and other costs and
expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

9.13 SEVERABILITY. The parties stipulate that the terms and provisions of this Agreement are fair
and reasonable as of the date of this Agreement. However, any provision of this Agreement shall be
determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder
of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force
and effect and shall in no way be affected, impaired or invalidated. If, moreover, any of those
provisions shall for any reason be determined by a court of competent jurisdiction to be
unenforceable because excessively broad or vague as to duration, activity or subject, it shall be
construed by limiting, reducing or defining it, so as to be enforceable.

EXHIBIT C

Explanation of “BENEFICIAL OWNERSHIP”

Securities that are subject to a power to vote or dispose are deemed beneficially owned by the
person who holds such power, directly or indirectly. This means that the same securities may be
deemed beneficially owned by more than one person, if such power is shared. In addition, the
beneficial ownership rules provide that shares which may be acquired upon exercise of an option or
warrant, or which may be acquired upon the termination of a trust, discretionary account or similar
arrangement, which can be effected within a period of 60 days from the date of determination, are
deemed to be “beneficially” owned. Furthermore, shares that are subject to rights or powers even
though such rights or powers to acquire are not exercisable within the 60-day period may also be
deemed to be beneficially owned if the rights or powers were acquired “with the purpose or effect
of changing or influencing the control of the Issuer or in connection with or as a participant in
any transaction having such purpose or effect.”

In determining whether securities are “beneficially owned,” benefits which are substantially
equivalent to those of ownership by virtue of any contract, understanding, relationship, agreement
or other arrangement should cause the securities to be listed as “beneficially owned.”

Thus, for example, securities held for a person’s benefit in the name of others or in the name
of any estate or trust in which such person may be interested should also be listed. Securities
held by a person’s spouse, children or other members of such person’s family who are such person’s
dependents or who live in such person’s household should be listed as “beneficially owned” unless
such person does not enjoy benefits equivalent to those of ownership with respect to such
securities.

If a person has a proprietary or beneficial interest in a controlled corporation, partnership,
personal holding company, trust or estate which owns of record or beneficially any securities, such
person should state the amount of such securities owned by such controlled corporation,
partnership, personal holding company, trust or estate in lieu of allocating such person’s
proprietary interest, and by note or otherwise, please indicate that. In any case, the name of the
controlled corporation, partnership, personal holding company, or estate must be stated.

In all cases the nature of the beneficial ownership should be stated.
