Shares as follows:

                                         Number of                      % of

         MMRCH                           1,536,005                      9.7%

         The aggregate number of Shares beneficially owned by MMRCH to which
this Schedule 13D/A relates is 1,536,005, representing in the aggregate 9.7% of
the 15,765,332 Shares outstanding and 3.0% of the Shares outstanding assuming
conversion of the 35,687,735 shares of Series A Convertible Preferred Stock of
Arch ("Series A Preferred"), in each case as reported in Arch's Form 10-K filed
on March 18, 2002. MMRCH has the sole power to vote and the sole power to

         As disclosed in Arch's Form 8-K filed on November 9, 2001, pursuant to
a Letter Agreement dated November 8, 2001, Arch issued 1,636,729 shares of

Trident Partnership, L.P. ("Trident I"), Trident I received 391,761 Shares on
April 9, 2002, as a result of a cashless exercise of its 1,386,079 Class A
Warrants. The Warrants had an exercise price of $20.00 per share, and the
cashless exercise was based on the closing price of $27.88 for the Shares on
April 8, 2002, the day prior to the date on which notice Trident I provided its
notice of exercise. Trident I also reported that it sold 640,700 Shares in
market transactions on April 9, 2002, at an average net per Share price of
$27.05 (or approximately $17.3 million in the aggregate). Following these
transactions, Trident I reported that it continued to own 1,061 Shares. MMRCH is
a limited partner in Trident I and a minority shareholder in the general partner
of Trident I. MMC Capital also serves as an investment advisor to Trident I. MMC
and MMRCH disclaim that they beneficially own any Shares beneficially owned by
Trident I.

         To the knowledge of MMC and MMRCH, none of their respective officers
and directors beneficially own any Shares.
