indenture, agreement or other instrument, or result in the creation or
imposition of any lien, charge, restriction, claim or encumbrance of any nature

delivered by the Company and constitutes the legal, valid and binding obligation
of the Company, enforceable against the Company in accordance with its terms,
except as may be limited by bankruptcy, insolvency, fraudulent transfer or other

matter), regardless of whether enforceability is considered in a proceeding in
equity or at law.

Noteholders the Company's Annual Report on Form 10-K for the fiscal year ended

Commission (or if amended or superseded by a filing prior to the date of this
Agreement, on the date of such filing), did not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. Since June 30, 2000,
there has been no material adverse change in the business, financial condition
or results of operations of the Company and its subsidiaries, taken as a whole.
