EXHIBIT A

Form of Company Counsel Opinion

Based on the foregoing, and subject to the assumptions and qualifications set forth below, we are of the opinion that:

1. The Company is a corporation incorporated, validly existing and in good standing under the laws of New York, and has the requisite corporate power and authority to conduct its business, and to own, lease and operate its properties, as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2002.

2. The Company has the requisite corporate power and authority to execute, deliver and perform its obligations under the Exchange and Termination Agreement (the “ Exchange Agreement ”), including issuance of the Common Shares, in accordance with the terms of the Exchange Agreement. The execution and delivery of the Exchange Agreement by the Company, the performance of the obligations of the Company thereunder and the consummation by it of the transactions contemplated therein have been duly authorized by the Company’s Board of Directors and no further consent or authorization of the Company, its Board of Directors or its stockholders is required therefor. The Exchange Agreement has been duly executed and delivered by the Company and constitutes the valid and binding agreement of the Company, enforceable against the Company in accordance with its terms.

3. The issuance of the Common Shares has been duly authorized, and when issued in accordance with the terms of the Exchange Agreement, the Common Shares will be validly issued, fully paid and non-assessable and free of all taxes, liens, charges and preemptive rights with respect to the issue thereof.

4. As of the date hereof, the authorized common stock of the Company consists of 200,000,000 shares of Common Stock, par value $0.01 per share. None of such Common Stock or such Preferred Stock is subject to preemptive rights or other rights of the shareholders of the Company pursuant to the Certificate of Incorporation or the By-laws or under the New York Business Corporation Law. Except for the Series C Preferred Stock, to our knowledge, there are no securities or instruments containing anti-dilution or similar provisions that will be triggered by the issuance of the Common Shares in accordance with the terms of the Exchange Agreement.

5. Subject to the accuracy as to factual matters of the Investor’s representations in Section 2 of the Exchange Agreement, the Common Shares may be issued to you pursuant to the Exchange Agreement without registration under the 1933 Act or the securities laws of any state, and you will be able to utilize or tack the holding period applicable to the Series C Preferred Stock for purposes of Rule 144 under the 1933 Act in connection with sales of the Common Shares.

6. No authorization, approval, consent, filing or other order of any Federal or state governmental body, regulatory agency, self-regulatory organization or stock exchange or market, or any court, or, to our knowledge, any third party, is required to be obtained by the Company to

19

enter into and perform its obligations under the Exchange Agreement or for the issuance and sale of the Common Shares.

7. To our knowledge and other than that which has been publicly disclosed by the Company, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board or body or any governmental agency or self-regulatory organization pending or threatened against the Company or any of the properties of the Company which is reasonably be expected to have a material adverse effect on the business, properties, assets, operations, results of operations, financial condition or prospects of the Company taken as a whole or on the transactions contemplated by the Exchange Agreement.

8. The execution, delivery and performance by the Company of the Exchange Agreement, the consummation by the Company of the transactions contemplated thereby, and the compliance by the Company with the terms thereof, does not (a) violate, conflict with or constitute a default (or an event which, with the giving of notice or lapse of time or both, constitutes or would constitute a default) under (i) the Certificate of Incorporation or the By-laws, or (ii) any agreement, note, lease, mortgage, deed or other instrument to which the Company is a party or by which the Company is bound and which the Company has filed as an exhibit to its reports filed with the Securities Exchange Commission under the Securities Exchange Act of 1934, as amended (the “ 1934 Act ”) or which, to our knowledge, the Company otherwise is required or will be required to file as an exhibit to its reports under the 1934 Act; or (b) result in any violation of any statute, law, rule or regulation known to us to be applicable to the Company or, to the best of our knowledge, any order, writ, injunction or decree.

9. To our knowledge, the Company is not an “investment company” or any entity controlled by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended.

(A) The Company fails to deliver to an Investor Conversion Shares within 10 days of the Conversion Date on which such Investor satisfied the requirements for conversion of Preferred C Shares, which the Company legally may issue to such Investor; and

(B) The Company redeems or repurchasers any Common Stock or other equity security junior to the Preferred C Shares in contravention of the rights of the Preferred C Shares.

(v) Each Investor hereby agrees that it shall not sell or transfer or permit the transfer of any of its Preferred C Shares to any transferee unless such transferee agrees in writing for the benefit of the Company, which writing is delivered to the Company at the time of such transfer to be bound by the agreements and obligations under this Agreement, including this restriction on the transfer of the Preferred C Shares. Nothing in this Section 2(c)(iv), however, prevents the conversion of the Preferred C Shares by an Investor and the sale or transfer of the shares of Common Stock received by such Investor upon such conversion.

(vi) Each Investor acknowledges and agrees that the certificate for Preferred C Shares shall include a legend reflecting the restriction on transfer provided in Section 2(iv).

(vii) Each of the Investors hereby agrees that no adjustment to the terms, including the Conversion Price or Conversion Rate, as set forth in the Certificate of Amendment to the Company’s Certificate of Incorporation governing the Series C Preferred Stock, is required as a result of an exchange of Preferred C Shares by HFTP with the Company for shares of Common Stock prior to or concurrently with the Investors’ purchase of Preferred C Shares from HFTP.

Each Investor’s proportionate share shall be a fraction, the numerator of which is the amount of Series C Preferred Shares purchased by an Investor from HFTP and the denominator of which is the total amount of Series C Preferred Shares purchased from HFTP by all Investors. The foregoing sales limitation shall not apply to sales effected as per Common Stock prices greater than sixty cents ($.60). The Company may waive the foregoing sales limitation as to all, but not less than all Investors.

(l) Conversion Price . The Company acknowledges and agrees that pursuant to the Certificate of Amendment governing the Series C Preferred Stock, the sale of the shares of Common Stock under this Agreement will cause an adjustment to the Conversion Price of the Preferred C Shares to the sales price for such Purchased Shares to the extent such sales price is less than the applicable Conversion Price immediately prior to the sale of the Purchased Shares.

(m) Holding Period of Preferred C Shares . The Company also acknowledges and agrees that HFTP purchased the Preferred C Shares directly from the Company on October 10, 2000 and has held the Preferred C Shares continuously since such date. The Company further acknowledges and agrees that HFTP has represented to it as of the date hereof that it is not an affiliate of the Company. In addition, the Company has delivered to the Investors, as of the date hereof, the opinion of Anslow & Jaclin, LLP, Freehold, New Jersey to the effect that HFTP is not an affiliate of the Company and the Investors are entitled to tack the holding period of HFTP of the Preferred C Shares sold by HFTP to the Investors to the Investors own holding period for those shares for purposes of the holding period requirements of Rule 144(d) under the 1933 Act. The Company agrees not to take any position contrary to such representation and opinion with respect to the Investors’ holding of the Preferred C Shares.

(n) Conversion Limitations of Series C Preferred Stock . The Company acknowledges that the provisions of the Series C Documents and the Certificate of Amendment of the Certificate of Incorporation setting forth the terms of the Series C Preferred Stock that impose limitations on the amount of Preferred C Shares that may be converted into Common Stock at any time by a holder of Preferred C Shares only apply to each holder, of record or beneficially, of Preferred C Shares and its affiliates, and such a holder is not required to aggregate its ownership of Company securities with the ownership of Company securities by any other holder of Preferred C Shares (not an affiliate of it or acting in concert with it) for purposes of the limitations on conversion of Preferred C Shares into Common Stock by a holder thereof set forth in the Certificate of Amendment; and the Company agrees that it shall not take a position contrary to such application of those conversion limitations. Thus, based on the representations of the Investors in Section 3(h) of this Agreement, none of the Investors would have to aggregate its ownership of Company securities with ownership of such securities of HFTP for purposes of calculating a conversion limitation governing the Preferred C Shares.

(o) The Company acknowledges its obligation in accordance with the Series C Documents to issue shares of its Common Stock upon the conversion of Preferred C Shares by the Investors. As of the transfer of the Preferred C Shares by HFTP to the Investors, there were no defaults in the obligations of a holder of Preferred C Shares which are assumed by the Investors, the rights of the Investors to the rights and obligations of the Preferred C Shares in accordance with the Series C Documents is not impaired in any way, and the Company does not have any defenses to its obligations under the Series C Documents against those rights and obligations of the Investors.
