Dear Valued Customer:

I am pleased to tell you about an investment opportunity and, just as importantly, to request your vote. Pursuant to a Plan of Conversion and Reorganization (the “Plan”), our organization will convert from the mutual holding company to the stock form of organization. To accomplish the conversion, Delanco Bancorp, Inc., a newly formed New Jersey corporation to become the holding company for Delanco Federal Savings Bank (“Delanco Federal”), is conducting an offering of shares of its common stock. Enclosed you will find a Prospectus, a Proxy Statement and a Questions and Answers Brochure describing the conversion, the offering and the Plan.

THE PROXY VOTE:

Your vote is extremely important for us to meet our goals. Although we have received conditional regulatory approval, the Plan is also subject to approval by Delanco Federal’s eligible customers. NOT VOTING YOUR ENCLOSED PROXY CARD(S) WILL HAVE THE SAME EFFECT AS VOTING ‘‘AGAINST’’ THE PLAN. Note that you may receive more than one Proxy Card, depending on the ownership structure of your accounts at Delanco Federal. Please vote all the Proxy Cards you receive — none are duplicates! To cast your vote, please sign each Proxy Card and return the card(s) in the Proxy Reply Envelope provided. Alternatively, you may vote by telephone or the Internet by following the simple instructions on the Proxy Card. Our Board of Directors urges you to vote ‘‘FOR’’ the Plan.

Please note:

THE STOCK OFFERING:

As an eligible Delanco Federal customer, you have non-transferable rights, but no obligation, to purchase shares of common stock during our Subscription Offering before any shares are made available for sale to the general public. The common stock is being offered at $8.00 per share, and there will be no sales commission charged to purchasers during the offering.

Please read the enclosed materials carefully. If you are interested in purchasing shares of common stock, complete the enclosed Stock Order Form and return it with full payment, in the Stock Order Reply Envelope provided.

Dear Valued Customer:

I am pleased to tell you that, pursuant to a Plan of Conversion and Reorganization (the “Plan”), Delanco Federal Savings Bank (“Delanco Federal”) will convert from the mutual holding company to the stock holding company form of organization. Also pursuant to the Plan, Delanco Bancorp, Inc., a newly formed New Jersey Corporation, is conducting an initial public offering of its common stock. Upon completion of the conversion and related stock offering, Delanco Bancorp, Inc. will become the parent company for Delanco Federal.

THE PROXY VOTE:

Your vote is extremely important for us to meet our goals. Although we have received conditional regulatory approval, the Plan is also subject to approval by the Bank’s eligible customers. NOT VOTING YOUR ENCLOSED PROXY CARD(S) WILL HAVE THE SAME EFFECT AS VOTING “AGAINST” THE PLAN. Note that you may receive more than one Proxy Card, depending on the ownership structure of your accounts at Delanco Federal. Please vote all the Proxy Cards – none are duplicates. To cast your vote, please sign each Proxy Card and return the card(s) in the Proxy Reply Envelope provided. Alternatively, you may vote by telephone or the Internet by following the simple instructions on the Proxy Card. Our Board of Directors urges you to vote “FOR” the Plan.

Although you may vote on the Plan, we regret that Delanco Bancorp, Inc. is unable to offer its common stock to you because the small numbers of customers in your jurisdiction makes registration or qualification of the common stock under your state securities laws prohibitively expensive or otherwise impractical.

If you have any questions about the Plan or voting, refer to the enclosed information or call our Information Center.

Sincerely,

James E. Igo
