          (e) During the last five years, none of the Reporting Persons or, to
the best of their  knowledge,  any of their  directors or executive  officers,
have been a party to a civil proceeding of a judicial or  administrative  body
of competent jurisdiction and as a result of such proceeding was or is subject
to a  judgment,  decree or final  order  enjoining  future  violations  of, or
prohibiting  or mandating  activities  subject to federal or state  securities
laws or finding any violation with respect to such laws except as noted below:

          On November 3, 2004, a jury in Houston,  Texas convicted four former
Merrill Lynch  employees of criminal  misconduct in connection with a Nigerian
barge  transaction  that the government  alleged helped Enron Corp.  ("Enron")
inflate  its 1999  earnings  by $12  million.  The jury  also  found  that the
transaction  led to investor losses of $13.7 million.  In 2003,  Merrill Lynch
agreed to pay $80 million to settle Securities and Exchange Commission ("SEC")
charges  that it aided and abetted  Enron's  fraud by engaging in two improper
year-end  transactions in 1999, including the Nigerian barge transaction.  The
$80 million paid in connection  with the settlement  with the SEC will be made
available to settle  investor  claims.  In September  2003,  the United States
Department  of Justice  (the  "Justice  Department")  agreed not to  prosecute
Merrill Lynch for crimes that may have been committed by its former  employees
related to certain transactions with Enron, subject to certain understandings,
including  Merrill Lynch's  continued  cooperation  with the  Department,  its
acceptance  of  responsibility  for conduct of its former  employees,  and its
agreement to adopt and  implement new policies and  procedures  related to the
integrity of client and counter-party financial statements, complex structured
finance transactions and year-end transactions.

          In March 2005,  Merrill Lynch reached  agreements  with the State of
New Jersey and the New York Stock  Exchange  ("NYSE") and reached an agreement
in principal  with the State of  Connecticut  pursuant to which Merrill Lynch,
without  admitting or denying the allegations,  consented to a settlement that
included  findings that it failed to maintain certain books and records and to
reasonably   supervise  a  team  of  former  financial  analysts  ("FAs")  who
facilitated  improper  market  timing by a hedge fund  client.  Merrill  Lynch
terminated  the FAs in October  2003,  brought the matter to the  attention of
regulators, and cooperated fully in the regulators review. The settlement will
result in aggregate payments of $13.5 million.

          In March 2005,  Merrill Lynch reached an agreement in principal with
the NYSE pursuant to which  Merrill  Lynch,  without  admitting or denying the
allegations,  will consent to a settlement that includes  findings with regard
to certain matters relating to the failure to deliver prospectuses for certain
auction  rate  preferred  shares and  open-end  mutual  funds;  the failure to
deliver product descriptions with




                                                            Page 7 of 12 Pages

regard   to   certain  exchange-traded  funds;  the  failure  to  ensure  that
proper registration qualifications were obtained for certain personnel; issues
with regard to the retention, retrieval and review of e-mails; isolated lapses
in branch  office  supervision;  late  reporting  of  certain  events  such as
customer complaints and arbitrations; the failure to report certain complaints
in  quarterly  reports  to  the  NYSE  due  to a  system  error;  and  partial
non-compliance  with Continuing  Education  requirements.  The settlement will
result in a payment of $10 million to the NYSE.

          On April 28, 2003, the SEC, NYSE, National Association of Securities
Dealers,   Inc.   ("NASD"),   and   state   regulators   announced   that  the
settlements-in-principle  that the  regulators  had  disclosed on December 20,
2002 had been  reduced  to final  settlements  with  regard to ten  securities
firms,  including  Merrill  Lynch.  On October  31,  2003,  the United  States
District  Court for the  Southern  District  of New York  entered  into  final
judgments in connection  with the April 28, 2003,  research  settlements.  The
final  settlements  pertaining to Merrill Lynch,  which involved both monetary
and non-monetary relief set forth in the regulators' announcements, brought to
a conclusion the regulatory  actions  against Merrill Lynch related to alleged
conflicts of interest affecting research analysts.  Merrill Lynch entered into
these settlements without admitting or denying the allegations and findings by
the regulators,  and the settlements did not establish wrongdoing or liability
for purposes of any other proceedings.

Item 4.   Purpose of Transaction

          Item 4 is hereby amended to add the following at the end thereof:

          On August 2, 2005,  the Issuer entered into an Agreement and Plan of
Merger (the "Merger  Agreement")  with First  Reserve Fund X, L.P., a Delaware
limited  partnership  ("First  Reserve"),  CI  Acquisition,  Inc.,  a Delaware
corporation  and  wholly-owned   subsidiary  of  First  Reserve  (the  "Merger
Subsidiary"),  MLC, MLPFS,  OCM Principal  Opportunities  Fund II, L.P., Audax
Chart LLC,  Carl  Marks  Strategic  Investments,  L.P.,  Carl Marks  Strategic
Investments  III,  L.P.,  Van Kampen Senior Loan Fund,  GE Capital CFE,  Inc.,
Arthur S. Holmes Trust U/A 03/04/03 and Christine H. Holmes Trust U/A 03/04/03
(collectively, the "Principal Stockholders").

          Subject  to the terms and  conditions  of the Merger Agreement,  the
Merger  Subsidiary  has agreed to acquire  all the  outstanding  shares of the
Issuer  for a cash  purchase  price of $65.74  per  share,  less the  Issuer's
transaction  expenses.  In addition,  the holders of the Issuer's  outstanding
warrants and options will receive the same per share cash purchase  price less
the exercise  price of the warrants and options.  The Merger  Subsidiary  will
first purchase the shares owned by the Principal  Stockholders.  Following the
purchase of the Principal  Stockholders' shares and the purchase of additional
shares, if any,




                                                            Page 8 of 12 Pages

required   for   the   Merger   Subsidiary   to  own  at   least   90%  of the
Issuer,  the Merger  Subsidiary will be merged with and into the Issuer,  with
the Issuer continuing as the surviving  corporation.  The same per share price
paid to the  Principal  Stockholders  will be paid to the  Issuer's  remaining
stockholders. The transaction is subject to the receipt of necessary approvals
under applicable  antitrust and competition  laws and other customary  closing
conditions.

          The  summary of the  Merger  Agreement  contained  in this Item 4 is
qualified in its entirety by reference to the Merger Agreement.  A copy of the
Merger  Agreement is filed  as Exhibit 2.1 to  the  Issuer's Current Report on
Form 8-K  filed  with the SEC on August 8, 2005 and is incorporated  herein by
reference.

Item 5.   Interest in Securities of the Issuer.

          According  to  information  provided  by the  Issuer  in the  Merger
Agreement, the number of Shares outstanding was 5,360,409 as of July 18, 2005.

          (a) (i) By virtue of being a party to the Investor Rights  Agreement
(the "Investor  Rights  Agreement")  (a copy of which was previously  filed as
Exhibit 4 to  the  Initial  Statement),  the Reporting Persons, to the best of
their knowledge, may be deemed to be the beneficial owner of 4,537,122 Shares,
collectively held by the Stockholder Parties.  This amount represents 84.6% of
the total number of Shares outstanding.

          (ii) The  Reporting  Persons  are the  direct  beneficial  owners of
225,588 Shares. Their ability to vote or dispose of these shares is controlled
by the terms of the Investor Rights  Agreement (for a description of the terms
of the Investor Rights Agreement see Exhibit 4 of the Initial Statement). This
amount   represents   approximately   4.2%  of  the  total  number  of  Shares
outstanding.

          (b) The Reporting Persons have the sole power to vote and dispose of
225,588 Shares,  subject to the terms of the Investor Rights  Agreement (for a
description of the terms of the Investor Rights Agreement see Exhibit 4 of the
Initial Statement).

          (c) Except for the  transactions  described in Item 4 herein,  there
have been no  transactions  effected  with respect to the Shares since June 9,
2005 (60 days prior to the date hereof) by any of the Reporting Persons.

          (d) Not applicable.
