Private notes may be tendered in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

This will instruct you, the registered holder and/or book-entry transfer facility participant, as to the action to be taken by you relating to the exchange offer with respect to the private notes held by you for the account of the undersigned, upon and subject to the terms and conditions set forth in the prospectus and the letter of transmittal.

By acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act in connection with any resale of such exchange notes, the undersigned is not deemed to admit that it is an “underwriter” within the meaning of the Securities Act; and

● the undersigned is not acting on behalf of any person who could not truthfully make the foregoing representations.

● you, on behalf of the undersigned, agree to the terms set forth in the letter of transmittal; and

If an executed copy of this instruction letter is returned, the entire principal amount of private notes held for the undersigned’s account will be tendered unless otherwise specified above.

The undersigned hereby represents and warrants that the undersigned (1) owns the private notes tendered and is entitled to tender such notes, and (2) has full power and authority to tender, sell, exchange, assign and transfer the private notes and to acquire exchange notes issuable upon the exchange of such tendered private notes, and that, when the same are accepted for exchange, Essex will acquire good, marketable and unencumbered title to the tendered private notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim or right or restriction or proxy of any kind.
