We will distribute to each holder of our common stock who is a record holder of our common stock on the record date, which is August 4, 2010, at no charge, one transferable subscription right for each share of common stock owned.

Each basic subscription right will entitle the rights holder to purchase 0.1166 of a share of our common stock at a price of $0.08 per share, the subscription price, upon timely delivery of the required documents and payment of the subscription price. Fractional shares of our common stock will not be issued since we will round down the aggregate number of shares that the rights holder is entitled to receive to the nearest whole number.

Subject to allocation and availability as described below, each subscription right also grants the holder an over-subscription privilege to purchase additional shares of our common stock that are not purchased by other rights holders pursuant to their basic subscription rights. You are entitled to exercise your over-subscription privilege only if you exercise your basic subscription right in full.

If you elect to send in your Form of Exercise, Sale or Transfer of Subscription Rights to the Subscription Agent, Computershare Trust Company, N.A., you must also send the full purchase price for the number of additional shares that you have requested to purchase pursuant to exercise of your over-subscription privilege (in addition to the payment due for shares purchased through your basic subscription right). If an insufficient number of shares are available to fully satisfy all over-subscription privilege requests, the available shares will be distributed proportionately among rights holders who exercise their over-subscription privileges in accordance with the Prospectus. The Subscription Agent will return any excess payments by mail without interest or deduction promptly after the expiration of the subscription period.

If you wish to exercise your subscription rights, you must do so prior to 5:00 p.m., New York City time, on September 20, 2010, the expiration date for the rights offering, subject to earlier termination. After the expiration date, the subscription rights will expire automatically and will have no value.

You are not required to exercise any or all of your subscription rights. The rights are transferable and an application has been filed for the rights to be quoted on the Over-The-Counter Bulletin Board under the ticker symbol “ENSLR.OB” from August 6, 2010 until 5:00 p.m. New York City time on September 17, 2010, one business day prior to the Expiration Date. There is no guarantee that the application for quotation will be accepted.

You may sell your unexercised rights through the Subscription Agent or through a brokerage firm. If you would like to sell your rights through the Subscription Agent for no additional fee, you must deliver your executed Form of Exercise, Sale or Transfer of Subscription Rights at least four business days before the offering’s Expiration Date.
