from Fund VI on the Closing Date (as defined below), 4,130,473 shares of the
Common Stock (the "Shares") for an aggregate purchase price of $20,445,841 (the
"Purchase Price"). No further payment shall be required from the Company for the
Shares.

2. The Closing of the purchase and sale of the Shares by the Company shall take
place at the offices of Cravath, Swaine & Moore, 825 Eighth Avenue, New York,
New York 10019 at 10:00 a.m. New York City time on June 28, 2002 or such other
time and date as shall be mutually agreed to by the parties. Such time and date
are herein referred to as the "Closing Date".

3. At the Closing, Fund VI will deliver to the Company certificates evidencing
4,130,473 shares of Common Stock, and the Company will deliver to Fund VI a
certified or official bank check (or wire transfer) in an amount equal to the
Purchase Price.

4. Each of Fund VI and the Company hereby represents that (a) it has all
requisite power, authority and legal right to execute, deliver, enter into,
consummate the transactions contemplated by and perform its obligations under
this Letter Agreement; (b) its execution, delivery and performance of this
Letter Agreement has been duly authorized by all required corporate and other
actions; (c) it has duly executed and delivered this Letter Agreement, and this
Letter Agreement constitutes its legal, valid and binding obligations,
enforceable against each party in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other similar laws relating to the rights of creditors generally from time to
time in effect and to general principles of equity, including without
limitation, concepts of materiality, reasonableness, good faith and fair
dealing, regardless of whether in a proceeding in equity or at law; and (d) the
execution, delivery and performance by it of this Letter Agreement and any of
the transactions contemplated hereby do not and will not (i) violate







                                                                              12


or conflict with any provision of (A) its charter or by-laws, (B) any law, rule,

agreement, indenture or other instrument applicable to it or any of its
respective properties, or (C) any agreement or instrument to which it is a party
or by which it is bound, except in the case of subclauses (B) and (C), such
violations or conflicts which would not individually or in the aggregate have a
material adverse effect on the condition of its business.

5. Fund VI represents that it has, or as of the Closing Date will have, good and
valid title to the Shares, free and clear of all liens, charges, claims, pledges
or other encumbrances of any kind.

6. Each party's obligations hereunder are subject to the consummation of the
recapitalization of the certain shares of the Company's Series A Convertible
Preferred Stock, par value $.01 per share (the "Series A Preferred Stock") and
certain of the Warrants, each to purchase three-fifths of one share of Common
Stock pursuant to the Preferred Stock Recapitalization Agreements between each
of the holders of the Series A Preferred Stock and the Company.


7. This Letter Agreement shall be governed by the laws of the State of New York
applicable to contracts performed entirely therein. This Letter Agreement may
not be amended, modified or withdrawn without the consent of each of the parties
hereto.
