The SEC 3 Documents contain an audited consolidated balance sheet of the Company as of the end of the last completed fiscal year (the "Balance Sheet") and the related audited consolidated statements of income and cash flow for the year then ended (collectively, the "Financials"). The Financials have been prepared in accordance with GAAP applied on a basis consistent through the periods indicated and consistent with each other.

There is no fact which the Company has not disclosed to the Investors, orally or in writing, and of which any of the Company's directors or officers are aware, which could reasonably be anticipated to have a material adverse effect, upon the financial condition, operating results or assets, of the Company. Notwithstanding the foregoing, certain information provided by the Company to the Investors contained statements that are forward-looking, which are covered by the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995.

Other than the compliance with the first right to participate held by certain existing shareholder referred to in the Term Sheet, the execution, delivery and performance by the Company of this Agreement and the offer, issuance and sale of the Shares require no consent of, action by or in respect of, or filing with, any individual or entity, governmental body, agency, or official other than filings that have been made pursuant to applicable state securities laws and post-sale filings pursuant to applicable state and federal securities laws which the Company undertakes to file within the applicable time periods. 3.10 REGULATORY COMPLIANCE. The Company is not in violation of any applicable law, regulation, judgment, order or consent decree (of any governmental or non-governmental regulatory or self-regulatory agency or any organized exchange, including without limitation, the SEC, any state or local securities or insurance regulatory body, or the Internal Revenue Service), which violation is likely to have a material adverse effect on the Company's business, financial condition, or this transaction. 4 3.11 REGULATORY PROCEEDINGS, INVESTIGATIONS AND INQUIRIES. The Company has not been the subject of any material regulatory proceeding, examination, investigation or inquiry (known to the Company), including any pending or threatened regulatory proceeding, investigation or inquiry (known to the Company) (including without limitation any by governmental or non-governmental regulatory or self-regulatory agency or any organized exchange) relating to the Company. 3.12 REGISTRATION STATEMENT. The Company's Registration Statement on Form S-3 (the "Registration Statement") was declared effective by the SEC on March 31, 2003. The Registration Statement is effective on the date hereof and the Company has not received notice that the SEC has issued or intends to issue a stop order with respect to such Registration Statement or that the SEC otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened in writing to do so. The Registration Statement (including the information or documents incorporated by reference therein), as of the time it was declared effective, and any amendments or supplements thereto, each as of the time of filing, did not contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.
