| ·   | Ares can convert the preferred stock into common stock at any time at a conversion price of $9.60 per share, with conversion being calculated by taking the stated value (initially $100.00 per share) plus any amount added to stated value by way of dividends, then dividing by $9.60 to produce the number of shares of common stock issuable; |

| ·   | after the fifth anniversary of issuance, we can pay dividend in cash at our discretion; |
|--------------------|-----------------------------------------------------------------------------------------|

| ·   | upon our liquidation, prior to any holder of common stock or other junior securities, Ares shall receive in cash the greater of (i) the stated value plus any amount added by way of dividends (accelerated to include a full five years) or (ii) the amount it would receive if all shares of preferred stock were converted into common stock (calculated to include dividends accelerated to include a full five years); |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Ares can elect to treat any fundamental transaction as a liquidation event, which will entitle Ares to its liquidation preferences.  Following such election, in the event that we elect to make any payment such as a dividend or stock repurchase payment to a common shareholder, we will be required to repay Ares the full amount of the liquidation preference associated with the preferred stock.  However, if securities of another company are issued as consideration in a fundamental transaction, we have the option of requiring Ares to accept such common shares to satisfy the liquidation preference if shares are then quoted on the Nasdaq Stock Market or listed on the New York Stock Exchange.  The value of such shares is determined at 98% of the closing price on the trading day preceding the transaction and the shares are freely transferable without legal or contractual restrictions; |

| ·   | the preferred stock voting as a separate class elects (i) two directors to our board of directors for so long as Ares continues to hold preferred stock representing at least 20% of our “post-conversion equity” (outstanding common stock assuming conversions into common shares of all securities, including the preferred stock and assuming preferred stock dividends accelerated to include a full five years), (ii) one director for so long as it continues to hold at least 10% of post-conversion equity, and (iii) no directors below 10%; |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | the preferred stock voting as a separate class must approve (i) any alteration in its powers, preferences or rights, or in the certificate of designation, (ii) creation of any class of stock senior or pari passu with it, (iii) any increase in the authorized shares of preferred stock, and (iv) any dividends or distribution to common stock or any junior securities, except for pro rata dividends on common stock paid in common stock. These protective rights terminate on the first date on which there are outstanding less than 20% of the number of shares of preferred stock outstanding on the date the preferred stock was first issued; and |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | we believe that the timeframe to complete the permitting is reasonable. |
|--------------------|-------------------------------------------------------------------------|

| ·   | Landfill closure and post-closure liabilities are calculated by estimating the total obligation in current dollars.  Cost estimates equate the costs of third parties performing the work.  Any portion of the estimates which are based on activities being performed internally are increased to reflect a profit margin a third party would receive to perform the same activity.  This profit margin will be taken to income once the work is performed internally. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | The total obligation is carried at the net present value of future cash flows, which is calculated by inflating the obligation based upon the expected date of the expenditure using an inflation rate and discounting the inflated total to its present value using a discount rate.  The discount rate represents our credit-adjusted risk-free rate.  The resulting closure and post-closure obligation is recorded as an increase in this liability as airspace is consumed. |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Accretion expense is calculated based on the discount rate and is charged to cost of services and increases the related closure and post-closure obligation.  This expense will generally be less during the early portion of a landfill’s operating life and increase thereafter. |
