(b) Since December 31, 2002, (i) the business of the Company has been conducted in the ordinary course and (ii) there has been no material adverse change in the assets, properties, liabilities, business, affairs, results of operations, condition (financial or otherwise) or prospects of the Company on a consolidated basis. As of the Closing Date and as of the date hereof, there are no material liabilities of the Company which would be required to be provided for in a consolidated balance sheet of the Company as of any such date prepared in accordance with generally accepted accounting principles consistently applied, other than liabilities provided for in the financial statements referred to in Section 4.6(a).

4.17. No Burdensome Agreements.

To the best of the knowledge and belief of the Company, the Company is not a party to any contract or agreement with any Affiliate of the Company, the terms of which are less favorable to the Company than those which might have been obtained, at the time such contract or agreement was entered into, from a person who was not such an Affiliate.

4.18. Offering of Shares.

Except as set forth on Schedule 4.18, none of the Company, any agent or any other person acting on its behalf, directly or indirectly, (i) offered any of the Shares or any similar security of the Company (A) by any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) or (B) for sale to or solicited offers to buy any thereof from, or otherwise approached or negotiated with respect thereto with, any person other than (x) the Purchasers and (y) other investors, each of which the Company reasonably believed at the time of such sale, solicitation, approach or negotiation was an "accredited investor" within the meaning of Regulation D under the Securities Act or (ii) has done or caused to be done (or has omitted to do or to cause to be done) any act which act (or which omission) would result in bringing the issuance or sale of the Shares within the provisions of Section 5 of the Securities Act or the filing, notification or reporting provisions of any state securities laws.

The Company will use the net proceeds realized from the sale of the Shares to fund future development opportunities, for working capital purposes and for such other purposes as necessary or advisable in the sole judgment of the Company's Board of Directors.

from time to time, any "margin stock" as defined in said Regulation U, or any "margin stock" as defined in Regulation G of the Board of Governors of the Federal Reserve System, as amended from time to time, or for the purpose of purchasing, carrying or trading in securities within the meaning of Regulation T of the Board of Governors of the Federal Reserve System, as amended from time to time, or for the purpose of reducing or retiring any indebtedness which both (i) was originally incurred to purchase any such margin stock or other securities and (ii) was directly or indirectly secured by such margin stock or other securities.

4.23. Insurance.

(a) Schedule 4.23(a) contains a list and description of all insurance policies maintained by or on behalf of the Company on its assets, operations, properties and personnel. Such insurance is of the kind, covering such risks and in such amounts and with such deductibles and exclusions, as are consistent with those maintained by businesses similarly situated to the Company and are, in the opinion of the Company, reasonable for the business, assets and properties of the Company. All such policies are in full force and effect.

(b) The Company has not received any notice of cancellation or termination with respect to any material insurance policy thereof and there are no pending disputes or controversies between the Company, on the one hand, and the carrier of any such insurance policy, on the other.
