<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Security Valuation </B>Securities, including restricted securities, are valued according to the
following policy.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Securities are fair valued using an evaluated quote provided by an independent pricing service
approved by the Board of Trustees. Evaluated quotes provided by the pricing service may be
determined without exclusive reliance on quoted prices and may reflect appropriate factors such as
institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity,
type of issue, individual trading characteristics and other market data. Short-term obligations,
including commercial paper, having 60&nbsp;days or less to maturity are recorded at amortized cost which
approximates value. Securities with a demand feature exercisable within one to seven days are
valued at par. Debt securities are subject to interest rate and credit risks. In addition, all
debt securities involve some risk of default with respect to interest and principal payments.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Securities for which market quotations either are not readily available or are unreliable are
valued at fair value as determined in good faith by or under the supervision of the Trust&#146;s
officers following procedures approved by the Board of Trustees. Some of the factors which may be
considered in determining fair value are fundamental analytical data relating to the investment;
the nature and duration of any restrictions on transferability or disposition; trading in similar
securities by the same issuer or comparable companies; relevant political, economic or issuer
specific news; and other relevant factors under the circumstances.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Valuations change in response to many factors including the historical and prospective
earnings of the issuer, the value of the issuer&#146;s assets, general economic conditions, interest
rates, investor perceptions and market liquidity. Because of the inherent uncertainties of
valuation, the values reflected in the financial statements may materially differ from the value
received upon actual sale of those investments.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Fair Value Measurements </B>Generally Accepted Accounting Principles (GAAP)&nbsp;defines fair value as the
price that the Trust would receive to sell an investment or pay to transfer a liability in an
orderly transaction with an independent buyer in the principal market, or in the absence of a
principal market the most advantageous market for the investment or liability. GAAP establishes a
three-tier hierarchy to distinguish between (1)&nbsp;inputs that reflect the assumptions market
participants would use in pricing an asset or liability developed based on market data obtained
from sources independent of the reporting entity (observable inputs) and (2)&nbsp;inputs that reflect
the reporting entity&#146;s own assumptions about the assumptions market participants would use in
pricing an asset or liability developed based on the best information available in the
circumstances (unobservable inputs) and to establish classification of fair value measurements for
disclosure purposes. Various inputs are used in determining the value of the Trust&#146;s investments.
The inputs are summarized in the three broad levels listed below.
