Arlington Tankers Adopts Shareholder Rights Plan

HAMILTON, Bermuda, June 26 - Arlington Tankers Ltd. (NYSE: ATB) announced today that its Board of Directors has adopted a Shareholder Rights Plan.

In connection with the adoption of the Rights Plan, the Company's Board of Directors has designated a new series of Series A Junior Participating Preference Shares, and declared a dividend of one right to buy one one-thousandth of a Series A Junior Participating Preference Share for each outstanding Common Share of the Company to shareholders of record as of the close of business on July 7, 2008. Initially, these rights will not be exercisable and will trade with the Company's Common Shares.

Under the Rights Plan, the rights initially will become exercisable if a person becomes an "acquiring person" by acquiring 20% or more of the Company's common shares or commences a tender or exchange offer that could result in such person owning 20% or more of the Company's common shares. If a person becomes an acquiring person, each holder of a right (other than the acquiring person) would be entitled to purchase such number of common shares which are equivalent to the exercise price of the right divided by one-half of the current market price of a common share. If the Company is acquired in a merger or other business combination transaction after any such event, each holder of a right would then be entitled to purchase such number of common shares of the acquiring company's common shares which are equivalent to the exercise price of the right divided by one-half of the current market price of such common share.

Prior to any acquisition by a person of beneficial ownership of 20% or more of the Company's common shares, the Rights are redeemable for $0.00001 per Right at the option of the Company's Board.

"We recently announced that Arlington is engaged in a process to review and evaluate strategic alternatives to enhance shareholder value," said Edward Terino, Chief Executive Officer, President and Chief Financial Officer of Arlington. "We believe that the adoption of the Shareholder Rights Plan will allow us to proceed with this process in an orderly manner."

Further details about the Rights Plan will be contained in a Form 8-K to be filed with the Securities and Exchange Commission by the Company. 2
