 (a) Investment Purpose. The Investor is acquiring the Common Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or
exempted under the 1933 Act; provided, however, that by making the representations herein, the Investor does not agree to hold any of the Common Shares for any minimum or other specific term and reserves the right to dispose of the Common Shares at
any time in accordance with or pursuant to a registration statement or an exemption under the 1933 Act.

the Investor’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Investor set forth herein in order to determine the availability of such exemptions and the eligibility of the Investor to
acquire the Common Shares. 
  
 (d) No Governmental
Review. The Investor understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Common Shares or the fairness or suitability of the

beneficial owner of the Exchange Shares and, assuming that the Company delivered good and valid title to the Exchange Shares to the Investor free and clear of any and all voting agreements and arrangements, liens, encumbrances, claims, charges,

stockholders with respect to the execution and performance of this Agreement or the issuance of the Common Shares to the Investor. Without limiting the foregoing, (i) no issuance by the Company of securities to the Third Party Investors (the

certificates in such name and in such denominations as specified by the Investor and without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Investor by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5 will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Section 5, that the Investor shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and

Section 8, shall survive the Closing.

 14 








 agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby. 
  
 (k) Termination. In the event that the Closing shall not have occurred on or before February 16, 2004 due to the Company’s or the
Investor’s failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this
Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party; provided, however, that if this Agreement is terminated by the Company pursuant to this Section 9(k), the
Company shall remain obligated to reimburse the Investor for the expenses described in Section 4(d) above.

remedies set forth in this Agreement and all rights and remedies which have been granted at any time under any other agreement or contract and all of the rights which the Investor has under any law. Any person having any rights under any provision
of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

  
 (o) Mutual General Release. 
  
 (i) In consideration of the releases set forth in
Sections 9(o)(ii) and 9(o)(iii), and other consideration set forth herein, effective as of the Closing, the Investor, on behalf of itself and, to the extent permitted by law, its heirs, executors, administrators, devisees, trustees,
partners, directors, officers, shareholders, employees, consultants, representatives, predecessors, principals, agents, parents, associates, affiliates, subsidiaries, attorneys, accountants, successors, successors-in-interest and assignees
(collectively, the “Investor Releasing Persons”), hereby waives and releases, to the fullest extent permitted by law, but subject to Section 9(o)(iii) below, any and all claims, rights and causes of action, whether known or
unknown (collectively, the “Investor Claims”), that any of the Investor Releasing Persons had, currently has or then has against (i) the Company, (ii) any of the Company’s current or former parents, shareholders, affiliates,
subsidiaries, predecessors or assigns, or (iii) any of the Company’s or such other persons’ or entities’ current or former officers, directors, 
  

 15 








 employees, agents, principals, investors, signatories, advisors, consultants, spouses, heirs, estates,
executors, attorneys, auditors and associates and members of their immediate families (collectively, the “Company Released Persons”), including, without limitation, any Investor Claims arising out of or relating to the Securities
Purchase Agreement, Registration Rights Agreement between the Company and the Investor, dated as of October 5, 2000 (the “Registration Rights Agreement”) and the Series C Certificate of Amendment (collectively, the “Released
Documents”), other than Investor Claims arising from third party claims, actions or proceedings after the Closing. 
  
 (ii) In further consideration of the Investor entering into this Agreement, effective as of the Closing, the Company on behalf of itself
and, to the extent permitted by law, its heirs, executors, administrators, devisees, trustees, partners, directors, officers, shareholders, employees, consultants, representatives, predecessors, principals, agents, parents, associates, affiliates,
subsidiaries, attorneys, accountants, successors, successors-in-interest and assignees (collectively, the “Company Releasing Persons”), hereby waives and releases, to the fullest extent permitted by law, but subject to Section
9(o)(iii) below, any and all claims, rights and causes of action, whether known or unknown (collectively, the “Company Claims”), that any of the Company Releasing Persons had, currently has or then has against (i) the Investor,
(ii) any of the Investor’s current or former parents, shareholders, affiliates, subsidiaries, predecessors or assigns, or (iii) any of the Investor’s or such other persons’ or entities’ current or former officers, directors,
employees, agents, principals, investors, signatories, advisors, consultants, spouses, heirs, estates, executors, attorneys, auditors and associates and members of their immediate families (collectively, the “Investor Released
Persons”), including, without limitation, any Company Claims arising out of or relating to the Released Documents. 
  
 (iii) The Company and the Investor acknowledge that the releases set forth in Sections 9(o)(i), and 9(o)(ii) above do not
affect any claim which any Company Releasing Person or Investor Releasing Person may have under this Agreement or Section 5, 6 or 7 of the Registration Rights Agreement. 
  
 (p) Limitation of Beneficial Ownership. Notwithstanding anything to the contrary in this Agreement, in no event shall
the Investor have the right to convert any Series C Shares into, or exchange any Series C Shares for, shares of Common Stock to the extent that, after giving effect to such conversion or exchange the Investor (together with Investor’s
affiliates) would have beneficial ownership of in excess of 9.99% of the shares of the Common Stock outstanding immediately after giving effect to such conversion or exchange. For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the Investor and its affiliates shall include the number of shares of Common Stock issuable upon conversion or exchange of the Series C Shares with respect to which the determination of such sentence is being made, but
shall exclude the number of shares of Common Stock which would be issuable (i) upon conversion of the remaining unconverted Series C Shares beneficially owned 
  

 16 








 by Investor and its affiliates, and (ii) upon conversion or exercise of the unconverted or unexercised portion of any
other securities of the Company beneficially owned by the Investor and its affiliates subject to a limitation on conversion or exercise analogous to the limitation contained in this paragraph. Except as set forth in the preceding sentence, for
purposes of this paragraph beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this paragraph, in determining the number of outstanding shares of Common Stock,
the Investor may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by
the Company or its transfer agent setting forth the number of shares of Common Stock outstanding, including, without limitation, as disclosed in Section 3(d) of this Agreement. For purposes of compliance with this paragraph, upon the written or oral
request of the Investor, the Company shall reasonably promptly confirm orally and in writing to the Investor the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined
after giving effect to the conversion or exercise of securities of the Company, including the Series C Shares, by Investor or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.

 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.
