In our capacity as special Maryland counsel, we have reviewed the following: (a) The Charter of the Company, as amended to date, certified by an officer of the Company (the "Charter"); (b) A copy of the By-laws of the Company as in effect on the date hereof (the "By-laws"); (c) The Registration Statement; (d) The Option Plan; 2 (e) A specimen certificate evidencing the Shares; (f) Certified resolutions of the Board of Directors of the Company relating to the filing of the Registration Statement and the Option Plan; (g) A good standing certificate for the Company, of recent date, issued by the Maryland State Department of Assessments and Taxation; (h) An Officer's Certificate of the Company dated as of the date hereof as to certain factual matters (the "Officer's Certificate"); and (i) Such other documents as we have considered necessary to the rendering of the opinions expressed below. In such examination, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the aforesaid documents, the authenticity of all documents submitted to us as originals, the conformity with originals of all documents submitted to us as copies and that all public records reviewed are accurate and complete. As to any facts material to this opinion which we did not independently establish or verify, we have relied solely upon the Officer's Certificate and have not independently verified the matters stated therein. We assume also that the issuance, sale and number of Shares to be offered from time to time will be authorized and determined by proper action of the Board of Directors of the Company in accordance with the parameters described in the Registration Statement (each, a "Board Action") and in accordance with the Charter, By-Laws and applicable Maryland law. We further assume that prior to the issuance of any Shares there will exist under the Charter the requisite number of authorized but unissued shares of Common Stock. Based upon the foregoing and having regard for such legal considerations as we deem relevant, we are of the opinion and so advise you that the issuance of the Shares has been duly authorized, and, when issued, delivered and paid for in accordance with the terms and conditions of the Option Plan, such Shares will be validly issued, fully paid and non-assessable. The opinions expressed above are limited to the laws of Maryland, exclusive of the securities or "blue sky" laws of the State of Maryland.
