Value: Value is a measure of a stock's current worth.  MIR has a
current Value of $59.24 per share. Therefore, it is undervalued
compared to its Price of $43.12 per share.  Value is computed from
forecasted earnings per share, forecasted earnings growth,
profitability, interest, and inflation rates. Value increases when
earnings, earnings growth rate and profitability increase, and when
interest and inflation rates decrease. VectorVest advocates the
purchase of undervalued stocks. At some point in time, a stock's Price
and Value always will converge.

RV (Relative Value): RV is an indicator of long-term price
appreciation potential. MIR has an RV of 1.25, which is very good on a
scale of 0.00 to 2.00. This indicator is far superior to a simple
comparison of Price and Value because it is computed from an analysis
of projected price appreciation three years out, AAA Corporate Bond
Rates, and risk. RV solves the riddle of whether it is preferable to
buy High growth, High P/E stocks, or Low growth, Low P/E stocks.
VectorVest favors the purchase of stocks with RV ratings above 1.00.

RS (Relative Safety): RS is an indicator of risk. MIR has an RS rating
of 0.98, which is fair on a scale of 0.00 to 2.00. RS is computed from
an analysis of the consistency and predictability of a company's
financial performance, debt to equity ratio, sales volume, business
longevity, price volatility and other factors. A stock with an RS
rating greater than 1.00 is safer and more predictable than the
average stock in the VectorVest database. VectorVest favors the
purchase of stocks of companies with consistent, predictable financial
performance.

RT (Relative Timing): RT is a fast, smart, accurate indicator of a
stock's price trend. MIR has a Relative Timing rating of 0.94, which
is fair on a scale of 0.00 to 2.00.  RT is computed from an analysis
of the direction, magnitude, and dynamics of a stock's price movements
over one day, one week, one quarter and one year time periods. Once a
stock's price has established a strong trend, it is expected to
continue in that trend for the short-term. If a trend dissipates, RT
will gravitate toward 1.00. RT will explode from bottoms, dive from
tops, and reflect changes in price momentum. VectorVest favors the
purchase of stocks with RT ratings above 1.00.

VST (VST-Vector):  VST is the master indicator for ranking every stock
in the VectorVest database. MIR has a VST rating of 1.05, which is
fair on a scale of 0.00 to 2.00. VST is computed from the square root
of a weighted sum of the squares of RV, RS, and RT. Stocks with the
highest VST ratings have the best combinations of Value, Safety and
Timing. These are the stocks to own for above average, long-term
capital appreciation. VectorVest advocates the purchase of safe,
undervalued stocks rising in price.

Recommendation (REC): VectorVest gives a Buy, Sell, Hold
recommendation on every stock, every day. MIR has a Hold
recommendation. REC reflects the cumulative effect of all the
VectorVest parameters working together. These parameters are designed
to help investors buy safe, undervalued stocks rising in price. They
also help investors avoid or sell risky, overvalued stocks falling in
price. VectorVest recommends that investors buy high VST-Vector, Buy-
rated stocks in rising markets.

Stop (Stop-Price): Stop is an indicator of when to sell a long
position or cover a short position.  MIR has a Stop of $42.12 per
share. This is $1 below MIR's current closing Price. A stock's Stop is
computed from a 13 week moving average of its closing prices, and is
fine-tuned according to the stock's fundamentals. High RV, high RS
stocks have lower Stops, and low RV, low RS stocks have higher Stops.
In the VectorVest system, a stock gets a 'B' or 'H' recommendation if
its Price is above its Stop and an 'S' recommendation if its Price is
below its Stop.

GRT (Earnings Growth Rate): GRT reflects a company's one to three year
forecasted earnings growth rate in percent per year. MIR has a
forecasted Earnings Growth Rate of 13.00%, which VectorVest considers
to be good. GRT is computed from historical, current and forecasted
earnings data. It is updated each week for every stock in the
VectorVest database. GRT often foretells a stock's future price trend.
If a stock's GRT trend is upward, the stock's price will likely rise.
If GRT is trending downward, the stock's Price will probably fall.
VectorVest favors the purchase of stocks whose GRT is rising and is
greater than the sum of current inflation and interest rates, (8.74%).

EPS (Earnings per Share):  EPS stands for leading 12 months Earnings
Per Share.  MIR has a forecasted EPS of $3.05 per share. VectorVest
determines this forecast from a combination of recent earnings
performance and traditional fiscal and/or calendar year earnings
forecasts.

P/E (Price to Earnings Ratio): P/E is a popular measure of stock
valuation which shows the dollars required to buy one dollar of
earnings.  MIR has a P/E of 14.14. This ratio may be deemed to be high
or low depending upon your frame of reference. The average P/E of all
the stocks in the VectorVest database is 32.41. P/E is computed daily
using the formula: P/E = Price/EPS.

EY (Earnings Yield): EY reflects earnings per share as a percent of
Price. EY is related to P/E via the formula, EY = 100 / (P/E), and may
be used in place of P/E as a measure of valuation. EY has the
advantages that it is always determinate and can reflect negative
earnings. MIR has an EY of 7.07 percent. This is above the current
average of 3.07% for all the stocks in the VectorVest database. EY
equals 100 x (EPS/Price).

GPE (Growth to P/E Ratio): GPE is another popular measure of stock
valuation. It compares earnings growth rate to P/E ratio. MIR has a
GPE rating of 0.92.  High growth stocks are believed to be able to
justify high P/E ratios. A stock is commonly considered to be
undervalued when GPE is greater than 1.00 and overvalued when GPE is
below 1.00. Unfortunately, this rule of thumb does not take into
account the effect of interest rates on P/E ratios. The operative GPE
ratio of 1.00 is valid when and only when interest rates equal 10%.
With long-term interest rates currently at 6.04%, the operative GPE
ratio is 0.36. Therefore, MIR may be considered to be undervalued.

100.  MIR had a %Vol of 90.97% on 7/13/2007

CI (Comfort Index): CI is an indicator which reflects a stock's
ability to resist severe and/or lengthy price declines. MIR has a CI
rating of 1.64, which is excellent on a scale of 0.00 to 2.00. CI is
quite different from RS in that it is based solely upon a stock's long-
term price history. VectorVest advocates the purchase of high CI
stocks.
