The Weighted Average Price of the Company’s common stock will be calculated pursuant to the procedure set forth in the Offer to Exchange. The terms and conditions of the Exchange Offer are set forth in the Offer to Exchange and the accompanying Letter of Transmittal, which is attached as exhibit (a)(1) hereto.

This Schedule TO is filed in satisfaction of the reporting requirements of Rule 13e-4 under the Securities Exchange Act of 1934, as amended. The exchange offer is being made by the Company pursuant to an exemption from registration under Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”).

As of May 2, 2006, there were 842,673 shares of 5.00% Cumulative Convertible Preferred Stock outstanding.

The information set forth in the Offer to Exchange, including the accompanying Letter of Transmittal attached as Annex A thereto, is incorporated in this Amendment No. 1 to the Schedule TO by reference to all of the applicable items in the Schedule TO, except that such information is hereby amended and supplemented to the extent specifically provided herein.

The fifth sentence under “Questions and Answers About the Exchange Offer - Under what circumstances can the exchange offer be extended, amended or terminated” on page 4 of the Offer to Exchange, is hereby amended and restated to read as follows:

“We reserve the right, in our sole and absolute discretion, to terminate the exchange offer, at any time prior to the expiration date of the exchange offer if any condition to the exchange offer is not met.”

The second paragraph under “The Exchange Offer - Extension, Delay in Acceptance, Amendment or Termination” on pages 28 and 29 is hereby amended and restated to read as follows:

“We also expressly reserve the right, at any time or from time to time, subject to and in accordance with applicable law, to:

•

delay the acceptance for exchange of shares of Preferred Stock; or

•

waive any condition or otherwise amend the terms of the exchange offer in any respect prior to the expiration of the exchange offer, by giving oral, confirmed in writing, or written notice of such waiver or amendment to the exchange agent.”

“We expressly reserve the right, in our sole discretion, to terminate the exchange offer if any of the conditions set forth above in the first paragraph under “--Conditions to the Exchange Offer” shall have occurred.”

The Exchange Offer-United Kingdom Legal Matters

The section entitled “United Kingdom Legal Matters” on page 32 of the Offer to Purchase is hereby amended and restated to read as follows:

“United Kingdom Legal Matters

We are not aware of any holders of Preferred Stock that are subject to the laws of the United Kingdom. Under the laws and regulation of the United Kingdom, this offer to exchange and all other documentation relating to the exchange offer may only be distributed to persons in the United Kingdom who (i) have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act (2000) (Financial Promotion) Order 2005 or (ii) are persons to whom an invitation or inducement to engage in investment activity (within the remaining of section 21 of the Financial Services and Markets Act 2000 (as amended)) in connection with the exchange offer may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as “relevant persons”). Under the laws and regulations of the United Kingdom, this offer to exchange and all other documentation relating to the exchange offer may be directed only at relevant persons in the United Kingdom and must not be acted on or relied on by persons in the United Kingdom who are not relevant persons. The exchange offer is available in the United Kingdom only to relevant persons and will be engaged in only with relevant persons.

Since we are aware of no holders of Preferred Stock located in the United Kingdom, we have not authorized any offer to the public in the United Kingdom within the meaning of section 102B of the Financial Services and Markets Act 2000 (as amended) except to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities or otherwise in circumstances which do not require the publication by the company of a prospectus pursuant to the Prospectus Rules of the Financial Services Authority.”

The Exchange Offer-Accounting Treatment

The section entitled “Accounting Treatment” on page 34 of the Offer to Purchase is hereby amended and restated to read as follows:

“Accounting Treatment

As consideration for the exchange of the shares of Preferred Stock, we will issue shares of our common stock. We will record as a decrease to stockholders’ equity the fair value of the fees and expenses incurred by Chesapeake in connection with the exchange offer, which we estimate will be $350,000. The excess of the fair value of our common shares exchanged over the fair value of common shares issuable pursuant to the original conversion terms, which we estimate to be approximately $2.2 million, will be subtracted from net earnings to arrive at net earnings available to common shareholders in the calculation of earnings per share.”

Where You Can Find More Information

The first four paragraphs of “Where You Can Find More Information” on page 55 are hereby amended and restated to read as follows:

“We file annual, quarterly and special reports, proxy statements and other information with the SEC.
