THE TOTEM AVAILABLE DAILY WITHDRAWAL QUANTITY RULES AND FORMULA

%TMAC = Current Inventory/TMAC

------------------------------------------

If the %TMAC is > or = to 25.60%

then set the %TMDWQ = to 100%

------------------------------------------

If the %TMAC is < 25.60% and > to 0%

then

%TMDWQ = (19.9640) + (%TMAC * 2.1833) +

(%TMAC^2 * 0.0444)

------------------------------------

If the %TMAC is < or = to 0%

then set the %TMDWQ = to 0%

------------------------------------

TADWQ Calculation

TADWQ = (%TMDWQ/100) * TMDWQ

Rounded to the nearest whole Dekatherm (an integer)

-----------------------

Notes: (1) In the context of this formula, the %TMAC and %TMDWQ values are

taken as whole numbers, and not as decimal only numbers (i.e., use

40.0 not 0.40 or use 36.1234 not 0.361234).

(2) The coefficients are entered with four decimal places, and the

table is calculated with four decimal places, and then rounded for

display purposes.

(3) All calculations are initially performed utilizing four decimal

places. The final TADWQ, however, is rounded to the nearest whole

number.
