Up to                    Shares of Common Stock of

First Mariner Bancorp

Issuable Upon the Exercise of Subscription Rights at $           per Share

, 2010

To Our Clients:

We are sending this letter to you because we hold shares of common stock of First Mariner Bancorp for you.  First Mariner has commenced an offering of shares of common stock pursuant to the exercise of subscription rights distributed, at no charge, to all holders of record of shares of First Mariner common stock, par value $0.05 per share, at 5:00 p.m., Eastern Standard Time, on                     , 2009.  The subscription rights are described in the enclosed prospectus and evidenced by a rights certificate registered in your name or in the name of your nominee.

Summary Of The Terms Of The Rights Offering

·                  You will receive one subscription right for each share of First Mariner common stock you owned as of record at the close of business on                     , 2009.  Each subscription right entitles you to a basic subscription privilege and an over-subscription privilege.

·                  The basic subscription privilege of each subscription right gives you the opportunity to purchase            shares of First Mariner common stock at a subscription price of $           per share.  Fractional shares of First Mariner common stock resulting from the exercise of the basic subscription privilege will be eliminated by rounding down to the nearest whole share.  For example, if you owned 100 shares of First Mariner common stock as of 5:00 p.m., Eastern Standard Time, on the record date, you would have received 100 subscription rights and would have the right to purchase              shares of First Mariner common stock for $           per share.

·                  In the event that you purchase all of the shares of First Mariner common stock available to you pursuant to your basic subscription privilege, you may also choose to exercise an over-subscription privilege, subject to certain limitations and subject to allotment, to purchase a portion of any shares of First Mariner common stock that are not purchased by other shareholders of First Mariner through the exercise of their basic subscription privileges.

·                  The rights offering expires at 5:00 p.m., Eastern Standard Time, on                     , 2010.  First Mariner may extend the rights offering without notice to you until                     , 2010.  If you do not exercise your subscription rights before that time, they will expire and will not be exercisable for shares of First Mariner common stock.

·                  Once you elect to exercise your subscription rights, you cannot change your mind and revoke your election.
