Dear Valued Customer:

By now you’ve probably heard that, pending regulatory approval, Abington Savings Bank will become part of CompassBank on or about April 29, 2004.* We want to assure you that this is a positive move for everyone involved. That’s why we’re writing to you today — to tell you what’s happening and when, and any effect it may have on you.

The main difference you’ll notice will be that starting May 1, 2004, you will have access to more than

50 CompassBank ATMs throughout Southeastern Massachusetts, Cape Cod and Martha’s Vineyard.

There will be no change to your accounts and your Abington branch will maintain the same hours with the same courteous professionals to serve you.

For more than 145 years, CompassBank has been a solid, respected member of New England’s banking community. Just as important, its commitment to personal service is just as strong as Abington’s. Which is why Seacoast Financial, CompassBank’s parent company, has announced an agreement to merge with Sovereign Bank, the third largest bank in the region, with an outstanding CRA rating and a total commitment to its communities. We’re just awaiting regulatory and shareholder approval, which is expected in the coming months. You will hear directly from Sovereign about any impact the Sovereign merger may have on your accounts.

Your deposits will continue to be insured up to $100,000 per depositor by the FDIC. Additionally, you will continue to have excess deposit insurance coverage through the Depositors Insurance Fund (DIF) until the expected close of the Seacoast Financial Corporation acquisition by Sovereign Bancorp this summer. Customers who have deposit accounts at both Abington Savings Bank and CompassBank as of the Compass/Abington merger date will continue to have those deposits insured separately by the FDIC for six months from the date of the merger, which is currently expected to occur on April 29, 2004.

Certificates of deposit (CDs) will continue to have separate FDIC insurance until the first maturity date after that six-month period. If you have a CD that matures between the legal merger date of April 29, 2004, and October 29, 2004, and you renew it for the same term and amount, including accrued interest, this account will be insured separately from your other accounts until the new maturity date.

Should you have any questions about the combination with CompassBank or the upcoming merger of CompassBank with Sovereign Bank, please feel free to call us at 1-800-649-6663. You’re very important to us, and we want you to feel comfortable with what’s happening with your financial partner.

Sincerely,
