The registration of the Shares is being effected on a Form S-8 Registration Statement under the Securities Act of 1933, as amended (the "Securities Act").

Based on the foregoing and limited in all respects to Maryland law, it is our opinion that the Shares reserved under the Incentive Plan have been duly authorized and, upon payment for or issuance of the Shares pursuant to and in the manner described in the Incentive Plan, the Shares will be legally issued, fully paid and nonassessable. This opinion is rendered to you solely for your benefit in connection with the issuance of the additional Shares as described above. This opinion may not be relied upon by any other person or for any other purpose, and it should not be quoted, in whole or in part, or otherwise be referred to or be furnished to, any governmental agency (other than the Securities and Exchange Commission in connection with the aforementioned Registration Statement on Form S-8 in which this opinion is contained), or any other person or entity, without the prior written consent of this firm. 3 We note that, although certain portions of the Registration Statement on Form S-8 (the financial statements and schedules) have been included therein (through incorporation by reference) on the authority of "experts" within the meaning of the Securities Act, we are not experts with respect to any portion of the Registration Statement, including, without limitation, the financial statements or schedules or the other financial information or data included therein.
