In September, 2006, the FASB issued Statement of Financial Accounting Standards
No. 157, "Fair Valuation Measurements" ("FAS 157"). This standard clarifies the
definition of fair value for financial reporting, establishes a framework for
measuring fair value and requires additional disclosures about the use of fair
value measurements. FAS 157 establishes three different categories for
valuations. Level 1 valuations are those based upon quoted prices in active
markets. Level 2 valuations are those based upon quoted prices in inactive
markets or based upon significant observable inputs (i.e. yield curves;
benchmark interest rates; indices). Level 3 valuations are those based upon
unobservable inputs (i.e. discounted cash flow analysis; non-market based
methods used to determine fair valuation).

         Exchange Commission's rules and forms.

     (b) There was no change in the registrant's internal control over financial
         reporting (as defined in Rule 30a-3(d) under the Investment Company Act
         of 1940, as amended) that occurred during the registrant's last fiscal
         quarter that has materially affected or is reasonably likely to
         materially affect the registrant's internal control over financial
         reporting.

ITEM 3.  EXHIBITS.

     A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2(a) under the
