SECTION 4 REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS ------------------------------------------------ Each Purchaser hereby severally represents and warrants to the Company with respect to the purchase of Series A Shares by such Purchaser and with respect only to such Purchaser, as follows: 4.1 EXPERIENCE; SPECULATIVE NATURE OF INVESTMENT. The Purchaser (or its -------------------------------------------- principals or advisors) has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests.

The Purchaser is acquiring the Securities and the ---------- underlying Conversion Stock for investment for its own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof. The Purchaser understands that the Securities to be purchased hereby and the underlying Conversion Stock have not been, and will not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser's representations as expressed herein. The Purchaser is an "accredited investor" within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission. 4.3 RESTRICTED SECURITIES.

The Purchaser has had an opportunity to discuss the -------------- Company's business, management and financial affairs with the Company's management.

The Purchaser understands that such discussions, as well as any other written -11- <PAGE> information issued by the Company, were intended to describe certain aspects of the Company's business and prospects but were not an exhaustive description. The foregoing, however, shall not limit or modify the representations and warranties of the Company in Section 3 of this Agreement or the right of the Purchaser to rely thereon. 4.6 AUTHORIZATION. This Agreement and the Stockholders Agreement, when ------------- executed and delivered by the Purchaser, will constitute valid and legally binding obligations of the Purchaser enforceable in accordance with their terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies, and except as the indemnification provisions of Section 5.7 of the Stockholders Agreement may be limited by principles of public policy. 4.7 BROKERS OR FINDERS. The Purchaser has not engaged any broker, finder ------------------ or agent, and the Company has not, and will not, incur, directly or indirectly, as a result of any action taken by the Purchaser, any liability for brokerage or finders' fees or agents' commissions or any similar charges in connection with the Transaction Documents. In the event that the preceding sentence is in any way inaccurate, such Purchaser agrees to indemnify and hold harmless the Company and each other Purchaser from any liability for any commission or compensation in the nature of a finder's fee (and the costs and expenses of defending against such liability) for which the Company, any other Purchaser, or any of their officers, directors, employees or representatives, is responsible. 4.8 TAX LIABILITY.

The Purchaser understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions contemplated by the Transaction Documents.

Miscellaneous. ------------- (a) The terms of this Warrant shall be binding upon and shall inure to the benefit of any successors or assigns of the Company and of the holder or holders hereof and of the Common Stock issued or issuable upon the exercise hereof. (b) No Warrantholder, as such, shall be entitled to vote or receive dividends or be deemed to be a stockholder of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the holder of this Warrant, as such, any rights of a stockholder of the Company, or any right to vote, give or withhold consent to any corporate action, receive notice of meetings, receive dividends or subscription rights, or otherwise. (c) Receipt of this Warrant by the holder hereof shall constitute acceptance of and agreement to the foregoing terms and conditions.

The undersigned is purchasing these Securities for his, her or its own account for investment purposes only and not with a view to, or for the resale in connection with, any "distribution" thereof for purposes of the Securities Act of 1933, as amended (the "Securities Act"). -------------- (b) The undersigned understands that the Securities have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the investment intent of the undersigned as expressed herein. In this connection, the undersigned understands that, in the view of the Securities and Exchange Commission (the "SEC"), the statutory basis for such exemption may be --- unavailable if the undersigned's representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future.

This opinion is -------- rendered to you pursuant to Section 5.3 of the Purchase Agreement, and all terms used herein have the meanings defined for them in the Purchase Agreement unless otherwise defined herein. We have acted as counsel for the Company in connection with the negotiation of the Purchase Agreement and the Stockholders Agreement dated as of February 19, 1999 (the "Stockholders Agreement") (collectively the "Agreements") and the ---------------------- ---------- issuance of the Shares and the Warrants. As such counsel, we have made such legal and factual examinations and inquiries as we have deemed advisable or necessary for the purpose of rendering this opinion. In addition, we have examined, among other things, originals or copies of such corporate records of the Company, certificates of public officials and such other documents and questions of law that we consider necessary or advisable for the purpose of rendering this opinion, including without limitation the Transaction Certificate attached hereto (the "Transaction Certificate"). In such examination we have ----------------------- assumed the genuineness of all signatures on original documents, the authenticity of all documents submitted to us as originals, the conformity to original documents of all copies submitted to us as copies thereof, the legal capacity of natural persons and the due execution and delivery of all documents (except as to due execution and delivery by the Company) where due execution and delivery are a prerequisite to the effectiveness thereof. As used in this opinion, the expression "to our knowledge" with reference to matters of fact means that, after an examination of documents made available to us by the Company, and after inquiries of officers of the Company, but without any further independent factual investigation, we find no reason to believe that the opinions expressed herein are factually incorrect. Further, the expression "to our knowledge" with reference to matters of fact refers to the current actual knowledge of the attorneys of this firm who have worked on matters for the. H-1 <PAGE> Company solely in connection with the Agreements and the transactions contemplated thereby. Except to the extent expressly set forth herein or as we otherwise believe to be necessary to our opinion, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of the opinions set forth below. For purposes of this opinion, we are assuming that you have all requisite power and authority, and have taken any and all necessary corporate or partnership action, to execute and deliver the Agreements and we are assuming that the representations and warranties made by you in the Purchase Agreement and pursuant thereto are true and correct. We are also assuming that the Investors have purchased the Shares for value, in good faith and without notice of any adverse claims within the meaning of the District of Columbia Uniform Commercial Code. Based upon and subject to the foregoing, and except as set forth in the Purchase Agreement and the exhibits thereto, we are of the opinion that: 1. The Company is a corporation duly organized and (based solely on the attached Certificate of Good Standing issued by the Secretary of State of the State of Delaware) validly existing under, and by virtue of, the laws of the State of Delaware and is in good standing under such laws. The Subsidiary is a corporation duly formed and (based solely on the attached letter of confirmation from CT Corporation System) validly existing and in good standing under, and by virtue of the laws of the Commonwealth of Virginia, and is in good standing under such laws. Each of the Company and the Subsidiary has requisite corporate power to own and operate its properties and assets, and to carry on its business as presently conducted. 2. The Company has all requisite legal and corporate power to execute and deliver the Agreements, to sell and issue the Shares and the Warrants under the Purchase Agreement, to issue the Conversion Stock and to carry out and perform its obligations under the terms of the Agreements. 3. The authorized capital stock of the Company consists of 100,000,000 shares of Common Stock, of which 9,966,074 shares are issued and outstanding, and 25,000,000 shares of Preferred Stock, of which 2,827,168 shares are designated as Series A Shares, none of which are issued and outstanding prior to the Initial Closing, and 1,119,679 Series B Shares, all of which are issued and outstanding. All such issued and outstanding Series B Shares and shares of Common Stock have been duly authorized and validly issued and are fully paid and nonassessable and free of any preemptive or similar rights contained in the Restated Certificate or By-Laws of the Company.
