by the Investors and the fulfillment of those undertakings of the Investors
to be fulfilled prior to the Closing.

         4. Representations, Warranties and Covenants of the Company. The
Company hereby represents and warrants to, and covenants with, each of the
Investors, severally and not jointly, as follows:

         4.1 Organization and Standing. The Company has been duly
incorporated and is validly existing as a corporation in good standing
under the laws of the jurisdiction of its incorporation, has full corporate
power and authority to own or lease its properties and conduct its business
presently conducted, and is duly qualified as a foreign corporation and in
good standing in all jurisdictions in which the character of the property
owned or leased or the nature of the business transacted by it makes
qualification necessary (except where the failure to be so qualified would
not have a material adverse effect on the business, properties, financial
condition or results or operations of the Company).

         4.2 Corporate Power; Authorization. The Company has all requisite
corporate power to, and has taken all requisite corporate action to,
execute and deliver the Agreement, to sell and issue the Shares and to
carry out and perform all of its obligations under the Agreement. The
Agreement constitutes the legal, valid and binding obligation of the
Company, enforceable in accordance with its terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar
laws relating to or affecting the enforcement of creditors' rights
generally and (b) as limited by equitable principles generally. The
execution and delivery of the Agreement does not, and the performance of
the Agreement and the compliance with the provisions hereof and the
issuance, sale and delivery of the Shares by the Company will not
materially conflict with, or result in a material breach or violation of
the terms, conditions or provisions of, or constitute a material default
under, or result in the creation or imposition of any material lien
pursuant to the terms of: (i) the Articles of Incorporation or Bylaws of
the Company, each as in effect as of the date hereof; (ii) any statute, law
or rule applicable to the Company or regulation or any state or federal
order, judgment or decree applicable to the Company; (iii) or any
indenture, mortgage, material lease or other material agreement or
instrument to which the Company or any of its properties is subject.

         4.3 Issuance and Delivery of the Shares. The Shares, when issued
and paid for in compliance with the provisions of the Agreement, will be
validly issued, fully paid and nonassessable. The issuance and delivery of
the Shares is not subject to preemptive, co-sale, right of first refusal or
any other similar rights of the shareholders of the Company or any liens or
encumbrances.

         4.4 SEC Documents; Financial Statement. The Company has filed in a
timely manner all documents that the Company has been required to file with
the Securities and Exchange Commission (the "SEC") under Sections 13, 14(a)
and 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), during the twelve (12) months preceding the date of the Agreement.
As of their respective filing dates, all documents filed by the Company
with the SEC (the "SEC Documents") complied in all material respects with
the requirements of the Exchange Act. The SEC Documents as of their
respective dates did not contain any untrue statement of material fact or
omitted to state a material fact required to be stated therein or necessary
to make the statements made therein, in light of the circumstances under
which they were made, not misleading. As of their respective dates, the
financial statements of the Company included in the SEC Documents complied
as to form in all material respects with applicable accounting requirements
and the published rules and regulations of the SEC. Such financial
statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods
involved (except (i) as may be otherwise indicated in such financial
statement or the notes thereto or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be
condensed or summary statements), and fairly present in all material
respects the financial position of the Company and its subsidiaries as of
the dates thereof and the results of operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments).

         5. Representations, Warranties and Covenants of the Investors. The
Investors hereby make the following representations, warranties and
covenants, severally and not jointly:

         5.1 Prospectus. Each Investor has received the Prospectus.

         5.2 Foreign Laws. Each Investor, if outside the United States,
will comply with all applicable laws and regulations in each foreign
jurisdiction in which it purchases, offers, sells or delivers Shares or has
in its possession or distributes any offering material, in all cases at its
own expense.

         5.3 Authority; Validity. (a) Each Investor has full right, power,
authority and capacity to enter into the Agreement and to consummate the
transactions contemplated hereby and has taken all necessary action to
authorize the execution, delivery and performance of the Agreement; and (b)
such Agreement constitutes a valid and binding obligation of each 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).

         5.4 Investment Intent. Each Investor is purchasing Shares only for
its own account as principal, for investment purposes only, and not with a
view to, or for, resale, distribution or fractionalization thereof, in
whole or in part, within the meaning of the Securities Act.

         5.5 No Legal, Tax or Investment Advice. Each Investor understands
that nothing in the Agreement or any other materials presented to such
Investor in connection with the purchase and sale of the Shares 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 the Shares.

         6. Survival of Representations, Warranties and Agreements.
Notwithstanding any investigation made by any party to the Agreement, all
covenants, agreements, representations and warranties made by the Company
and each Investor herein shall survive the execution of the Agreement, the
delivery to each Investor of the Shares being purchased and the payment
therefor.

         7. Notices. All notices and other communications required or
permitted under the Agreement shall be effective upon receipt and shall be
in writing and may be delivered in person, by telecopy, overnight delivery

Investor shall have furnished to the other parties in writing. All notices
and other communications shall be effective upon the earlier of actual
receipt thereof by the person to whom notice is directed or (a) in the case

         8. Changes. The Agreement may not be modified or amended except
pursuant to an instrument in writing signed by the Company and the Investor
to which such change applies.

         9. Headings. The headings of the various sections of the Agreement

in any way be affected or impaired thereby.
