consolidated financial statements and notes thereto filed herewith reflect no
other changes from the consolidated financial statements and notes thereto filed
with the Form 10-Q on May 3, 2001.

     (e) Nextel Agreement - In January 2001, Arch agreed to sell its 900 MHz SMR
(Specialized Mobile Radio) licenses to Nextel Communications, Inc. Nextel will
acquire the licenses for an aggregate purchase price of $175 million and invest
$75 million in a new equity issue, Arch Series F 12% Redeemable Cumulative
Junior Preferred Stock. In February 2001, Nextel advanced $250 million in the
form of loans to a newly created, stand-alone Arch subsidiary that holds the
spectrum licenses until the transfers are approved. The new Arch subsidiary is
not permitted to engage in any business other than ownership and maintenance
of the spectrum licenses and will not have any liability or obligation with
respect to any of the debt obligations of Arch and its subsidiaries. Upon
transfer of the spectrum licenses to Nextel, the loan obligations will be
satisfied and $75 million of the loans will be converted into Arch series F 12%
Redeemable Cumulative Junior Preferred Stock. Arch acquired the SMR licenses as
part of its acquisition of PageNet in November 2000. In purchase accounting the
licenses were recorded at their fair value of $175.0 million and are included
the purchased Federal Communications Commission licenses balance in Note (b)
above. No gains or losses resulting from changes in the carrying amounts of
assets to be disposed of have been included in Arch's statement of operations.
No amortization has been recorded on the licenses. Revenues and operating
expenses related to the SMR operation included in the statement of operations
are immaterial.

     (g) Debt Exchanged for Equity - In the first quarter of 2001, Arch issued
8,793,350 shares of Arch common stock in exchange for $26.3 million accreted
value ($26.5 million maturity value) of its senior discount notes. Arch recorded
an extraordinary gain of $15.0 million on the early extinguishment of debt as a
result of these transactions.

     (h) Derivative Instruments and Hedging Activities - In June 1998, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standards (SFAS) No. 133 "Accounting for Derivative Instruments and Hedging
Activities". SFAS No. 133 requires that every derivative instrument be recorded
in the balance sheet as either an asset or liability measured at its fair value
and that changes in the derivative's fair value be recognized in earnings. Arch
adopted this standard effective January 1, 2001. The Company has not designated
any of the outstanding derivatives as a hedge under SFAS No. 133. The initial
application of SFAS No. 133 resulted in a $6.8 million charge, which was
reported as the cumulative effect of a change in accounting principle. This
charge represents the impact of initially recording the derivatives at fair
value as of January 1, 2001. The changes in fair value of the derivative
instruments will be recognized in other expense. The Company recorded other
expense of approximately $5.9 million related to the changes in fair value of
the derivatives during the period ended March 31, 2001.

     (i) Segment Reporting - The Company has determined that it has three
reportable segments; traditional paging operations, two-way messaging operations
and international operations. Management makes operating decisions and assesses
individual performances based on the performance of these segments. The
traditional paging operations consist of the provision of paging and other
one-way wireless messaging services to Arch's U.S. customers. Two-way messaging
operations consist of the provision of two-way wireless messaging services to
Arch's U.S. customers. International operations consist of the operations of the
Company's Canadian subsidiary.


                                       7


   Each of these segments incur, and are charged, direct costs associated with
their separate operations. Common costs shared by the traditional paging and
two-way messaging operations are allocated based on the estimated utilization of
resources using various factors that attempt to mirror the true economic cost of
operating each segment.

   The Company did not begin to market and sell its two-way messaging products
on a commercial scale until August 2000. The Company's Canadian subsidiary was
acquired in November 2000 in the PageNet acquisition. Prior to 2000,
substantially all of the Company's operations were traditional paging
operations. The following tables present segment financial information related
to the Company's segments for the periods indicated (in thousands):

     (1) Adjusted earnings before interest, income taxes, depreciation and
     amortization, as determined by Arch, does not reflect interest, income
     taxes, depreciation and amortization, restructuring charges, equity in loss
     of affiliate and extraordinary items; consequently adjusted earnings before
     interest, income taxes, depreciation and amortization may not necessarily
     be comparable to similarly titled data of other wireless messaging
     companies. Earnings before interest, income taxes, depreciation and
     amortization should not be construed as an alternative to operating income
     or cash flows from operating activities as determined in accordance with
     generally accepted accounting principles or as a measure of liquidity.
     Amounts reflected as earnings before interest, income taxes, depreciation
     and amortization or adjusted earnings before interest, income taxes,
     depreciation and amortization are not necessarily available for
     discretionary use as a result of restrictions imposed by the terms of
     existing indebtedness or limitations imposed by applicable law upon the
     payment of dividends or distributions among other things.
