                                EXPLANATORY NOTE


      Alaska Communications Systems Group Inc. (the "Registrant") filed a
Registration Statement on Form S-8 (Registration No. 333-92091) (the
"Registration Statement"), which originally registered 6,021,489 shares of
common stock, par value $.01 per share of the Registrant (the "Common Stock"),
reserved for issuance pursuant to four plans: (1) ALEC Holdings, Inc. 1999
Stock Incentive Plan (the "ALEC Plan"); (2) Alaska Communications Systems
Group, Inc. 1999 Stock Incentive Plan (the "Alaska Plan"); (3) Alaska
Communications Systems Group, Inc. 1999 Employee Stock Purchase Plan (the
"ESPP") ; and (4) Alaska Communications Systems Group, Inc. 1999 Non-employee
Director Stock Compensation Plan (the "Director Plan"), and collectively, the
"Plans".  In addition, pursuant to Rule 416 under the Securities Act of 1933,
the Registration Statement also covered an indeterminate number of additional
shares of the Common Stock issuable pursuant to the exercise of options and/or
awards granted or to be granted under the Plans to prevent dilution that may
result from any future stock splits, stock dividends or similar transactions
affecting the Common Stock.

      The Registrant amended the Alaska Plan to merge it with the ALEC Plan and
include all of the securities issued and issuable under the ALEC Plan in the
Alaska Plan. The merger preserved the original terms of any and all options
previously granted under the ALEC Plan and the original terms of any and all
options previously granted under the Alaska Plan. As of March 26, 2002, all
available shares allocated to the Alaska Plan will be issued pursuant to options
granted under the amended Alaska Plan.

      This Post-Effective Amendment No. 1 to the Registration Statement is filed
to allocate the 421,578 shares issued and outstanding under the ALEC Plan to the
Alaska Plan, the 2,448,449 shares reserved for options granted under the ALEC
Plan to the Alaska Plan, and the 540,459 shares available under the ALEC Plan to
the Alaska Plan. As of March 26, 2002, the number of shares issued and
outstanding under the Alaska Plan is 15,260, the number of shares reserved for
options granted under the Alaska Plan is 1,180,118, and the number of shares
available under the Alaska Plan is 304,622. As of March 26, 2002, the number of
shares issued and outstanding under the ESPP is 217,569, and the number of
shares available under the ESPP is 782,431. As of March 26, 2002, the number of
shares issued and outstanding under the Director Plan is 51,542, and the number
of shares available under the Director Plan is 98,458.
