The Investor acknowledges, represents and warrants to, and agrees with, the
Company and the Placement Agents that:

4.1 The Investor (a) is knowledgeable, sophisticated and experienced in making,
and is qualified to make decisions with respect to, investments in securities
presenting an investment decision like that involved in the purchase of the
Securities, including investments in securities issued by the Company and

 

6

--------------------------------------------------------------------------------

investments in comparable companies, (b) has answered all questions on the
Signature Page and the Investor Questionnaire and the answers thereto are true
and correct as of the date hereof and will be true and correct as of the Closing
Date and (c) in connection with its decision to purchase the Shares and the

the Disclosure Package and the documents incorporated by reference therein and
the Offering Information.

4.2 (a) No action has been or will be taken in any jurisdiction outside the
United States by the Company or the Placement Agents that would permit an
offering of the Securities, or possession or distribution of offering materials
in connection with the issue of the Securities in any jurisdiction outside the
United States where action for that purpose is required, (b) if the Investor is
outside the United States, it will comply with all applicable laws and
regulations in each foreign jurisdiction in which it purchases, offers, sells or
delivers Securities or has in its possession or distributes any offering
material, in all cases at its own expense and (c) neither of the Placement
Agents is authorized to make and has not made any representation, disclosure or
use of any information in connection with the issue, placement, purchase and
sale of the Securities, except as set forth or incorporated by reference in the
Base Prospectus, the Prospectus Supplement or any free writing prospectus.

4.3 (a) The Investor has full right, power, authority and capacity to enter into
this Agreement and to consummate the transactions contemplated hereby and has
taken all necessary action to authorize the execution, delivery and performance
of this Agreement, and (b) this Agreement constitutes a valid and binding
obligation of the Investor enforceable against the Investor in accordance with
its terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors’ and
contracting parties’ rights generally and except as enforceability may be
subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law) and except as
to the enforceability of any rights to indemnification or contribution that may
be violative of the public policy underlying any law, rule or regulation
(including any federal or state securities law, rule or regulation).

4.4 The Investor understands that nothing in this Agreement, the Prospectus, the
Disclosure Package, the Offering Information or any other materials presented to
the Investor in connection with the purchase and sale of the Units constitutes
legal, tax or investment advice. The Investor has consulted such legal, tax and
investment advisors and made such investigation as it, in its sole discretion,
has deemed necessary or appropriate in connection with its purchase of Units.
The Investor also understands that there is no established public trading market
for the Warrants being offered in the Offering, and that the Company does not
expect such a market to develop. In addition, the Company does not intend to
apply for listing of the Warrants on any securities exchange or other trading
market. The Investor understands that without an active market, the liquidity of
the Warrants will be limited.

as a result of the transactions contemplated hereby prior to the public
disclosure of that information by the Company in accordance with Section 13 of
this Annex.

Investor about the Offering, the Investor has not disclosed any information
regarding the Offering to any third parties (other than its legal, accounting
and other advisors) and has not engaged in any purchases or sales of the
securities of the Company (including, without limitation, any Short Sales (as
defined herein) involving the Company’s securities). The Investor covenants that
it will not engage in any purchases or sales of the securities of the Company
(including Short Sales) prior to the time that the transactions contemplated by
this Agreement are publicly disclosed. The Investor agrees that it will not use
any of the Securities acquired pursuant to this Agreement to cover any short
position in the Common Stock if doing so would be in violation of applicable
securities laws. For purposes hereof, “Short Sales” include, without limitation,
all “short sales” as defined in Rule 200 promulgated under Regulation SHO under
the Exchange Act, whether or not against the box, and all types of direct and
indirect stock pledges, forward sales contracts, options, puts, calls, short
sales, swaps, “put equivalent positions” (as defined in Rule 16a-1(h) under the
Exchange Act) and similar arrangements (including on a total return basis), and
sales and other transactions through non-U.S. broker dealers or foreign
regulated brokers.

5. Survival of Representations, Warranties and Agreements; Third Party
Beneficiary. Notwithstanding any investigation made by any party to this
Agreement or by either of the Placement Agents, all covenants, agreements,
representations and warranties made by the Company and the Investor herein will
survive the execution of this Agreement, the delivery to the Investor of the
Shares and Warrants comprising the Units being purchased and the payment
therefor. The Placement Agents shall be third party beneficiaries with respect
to the representations, warranties and agreements of the Investor in Section 4
hereof.
