Re:		Update on Chesapeake Utilities Corporation and Florida Public Utilities (FPU) Merger

We would like to take this opportunity to update you on our progress on several fronts. We continue to target the fourth quarter as the expected closing of the merger. Before the deal is completed, though, there are a number of steps and requirements along the way. We have highlighted some of the progress made to date and will do our best to keep you informed, as much as we can, given the nature of the transaction. First, the Joint Proxy — the document that we will send to all Chesapeake and FPU shareholders seeking their approval — is currently being drafted. Once the document is ready for filing and other required associated activities have been completed, we will file the document with the Securities Exchange Commission (SEC). We expect to engage in an interactive review process with the SEC. Once finalized, the document would be mailed to Chesapeake’s and FPU’s shareholders.

In terms of regulatory approvals, no additional filings or actions are required at this time with the Florida Public Service Commission and the Federal Energy Regulatory Commission in regards to approval of the transaction or securities to be issued by Chesapeake in conjunction with the merger. We have submitted the necessary regulatory filings with the Delaware and Maryland Public Service Commissions. We also filed notification of the proposed merger with the Federal Trade Commission (FTC) pursuant to Hart-Scott Rodino filings on May 4^th. To date, we have received no further communications from the FTC on this filing. Finally, as we move closer to the target closing date, we will also be filing with the New York Stock Exchange to list the Chesapeake shares that will be exchanged for the outstanding FPU shares.

As we move forward, we are turning our focus to the evolution of our two companies and will announce the members of the transition teams in the next few weeks. In advance of these teams forming and beginning down the path of integration, we would like to thank you in advance for your support. Your assistance and willingness to provide any information that is requested or needed, no matter what part or role you play, goes a long way and will help to ensure a smooth transition for everyone.

This is an exciting time for all of us. We expect that the shared future of Chesapeake and FPU will result in a new company of which we can all be proud. We appreciate your continued support and enthusiasm.
