On September 28, 2011, Towerstream Corporation (the “Company”) filed a supplement to the Company’s prospectus contained in the Registration Statement filed on Form S-3 dated June 13, 2007 (the “Prospectus”).  The prospectus supplement was filed to update the table under the section entitled “Selling Stockholders” of the Prospectus.

This update was required because certain warrants to purchase common stock were sold by certain third parties to other third parties or there was a change in custodian in which certain warrants were held.

The Company had no involvement in these transactions and there was no increase in the number or terms of warrants outstanding.
