ITEM 5.     INTEREST IN SECURITIES OF THE ISSUER.
            ------------------------------------

Item 5 of the Schedule 13D is hereby amended and supplemented by adding the
following:

(a)  The Reporting Persons beneficially own Common Shares of the Company by
     virtue of their ownership of an aggregate of 1,116,977 Common Shares, of
     an aggregate of 10,780,038 Preference Shares, which are convertible into
     Common Shares as described under Item 4, and of options to purchase an
     aggregate of 2,100 Common Shares, which options were issued to John L.
     Bunce, Jr. and David Tunnell, each of whom is an affiliate of the

     Reporting Persons, in consideration of their service as directors of
     the issuer, and which options are held for the benefit of the Reporting
     Persons. As of September 20, 2002, the Investors collectively beneficially
     owned an aggregate of 11,899,115 Common Shares, assuming the full
     conversion of the Preference Shares into Common Shares and the full
     exercise of the options to purchase Common Shares. By reason of its
     relationship with the Investors, under Rule 13d-3 under the Exchange Act,
     HFCI IV Bermuda may be deemed to own beneficially all of the Common Shares
     that are beneficially owned by the Investors.

     Assuming the full conversion of the Preference Shares into Common Shares,
     as of September 19, 2002, the 11,899,115 Common Shares collectively
     beneficially owned by the Reporting Persons would represent approximately
     33.3% of the outstanding Common Shares, after giving effect to the new
     issuance of Common Shares upon the full conversion of the Preference Shares
     into Common Shares, the full exercise of all options to purchase Common
     Shares and upon the exercise of the Warrants described herein and based on
     the 23,795,740 Common Shares outstanding as of June 30, 2002 as set forth
     in the Company's Form 10-Q for the quarter then ended.

(b)  The Investors collectively have beneficial ownership of 11,899,115 Common
     Shares, assuming the full conversion of the Preference Shares into Common
     Shares. Of these Common Shares, 10,780,038 Common Shares are represented by
     10,780,038 Preference Shares, which even if not converted into Common
     Shares would in the aggregate be entitled to the voting power equivalent to
     10,780,038 Common Shares. Each Investor exercises voting power and
     dispositive power over its holdings of such shares through its respective
     general partner, which, in turn, acts through its respective general
     partner.

(c)  On September 19, 2002, the Investors exercised Warrants to purchase an
     aggregate of 1,113,289 Common Shares, at a per share price of $20.00 or
     $22,265,780 in the aggregate. On September 1, 2002, Messrs. Bunce and
     Tunnell were issued an aggregate of 2,148 Common Shares in consideration of
     their services as directors of the issuer. Messrs. Bunce and Tunnell hold
     these Common Shares for the benefit of the Investors. Except as otherwise
     described herein, during the last sixty days there were no transactions
     effected by the Reporting Persons or by any of the persons set forth on
     Schedule I hereto.

(d)  Except as set forth in this Item 5, no person other than each respective
     record owner referred to herein of the Common Shares and the Preference
     Shares is known to have the right to receive or the power to direct the
     receipt of dividends from, or the proceeds from the sale of, such Common
     Shares or Preference Shares.

(e)   Not applicable.
