              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

    Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to ACS the principal amount of the Notes indicated
above. Subject to, and effective upon, the acceptance for exchange of such Notes
tendered hereby, the undersigned hereby exchanges, assigns and transfers to, or
upon the order of, ACS all right, title and interest in and to such Notes as are
being tendered hereby, including all rights to accrued and unpaid interest
thereon as of the Expiration Date. The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that said Exchange
Agent acts as the agent of ACS in connection with the Exchange Offer) to cause
the Notes to be assigned, transferred and exchanged. The undersigned represents
and warrants that it has full power and authority to tender, exchange, assign
and transfer the Notes and to acquire Exchange Notes issuable upon the exchange
of such tendered Notes, and that when the same are accepted for exchange, ACS
will acquire good and unencumbered title to the tendered Notes, free and clear
of all liens, restrictions, charges and encumbrances and not subject to any
adverse claim.

    The undersigned represents to ACS that (i) the Exchange Notes acquired
pursuant to the Exchange Offer are being obtained in the ordinary course of
business of the person receiving such Exchange Notes, whether or not such person
is the undersigned, and (ii) neither the undersigned nor any such other person
is engaged or intends to engage in, or has an arrangement or understanding with
any person to participate in, the distribution of such Exchange Notes. If the
undersigned or the person receiving the Exchange Notes covered hereby is a
broker-dealer that is receiving the Exchange Notes for its own account in
exchange for Notes that were acquired as a result of market-making activities or
other trading activities, the undersigned acknowledges that it or such other
person will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. The undersigned and any such other person
acknowledge that, if they are participating in the Exchange Offer for the
purpose of distributing the Exchange Notes, (i) they cannot rely on the position
of the staff of the Securities and Exchange Commission enunciated in EXXON
CAPITAL HOLDINGS CORPORATION (available April 13, 1989), MORGAN STANLEY & CO.,
INC. (available June 5, 1991) or similar no-action letters and, in the absence
of an exemption therefrom, must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with the resale
transaction and (ii) failure to comply with such requirements in such instance
could result in the undersigned or any such other person incurring liability
under the

                                       3

Securities Act for which such persons are not indemnified by ACS. If the
undersigned or the person receiving the Exchange Notes covered by this letter is
an affiliate (as defined under Rule 405 of the Securities Act) of ACS, the
undersigned represents to ACS that the undersigned understands and acknowledges
that such Exchange Notes may not be offered for resale, resold or otherwise
transferred by the undersigned or such other person without registration under
the Securities Act or an exemption therefrom.

    The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed by the Exchange Agent or ACS to be
necessary or desirable to complete the exchange, assignment and transfer of
tendered Notes or transfer ownership of such Notes on the account books
maintained by a book-entry transfer facility. The undersigned further agrees
that acceptance of any tendered Notes by ACS and the issuance of Exchange Notes
in exchange therefor shall constitute performance in full by ACS of its
obligations under the Registration Rights Agreement and that ACS shall have no
further obligations or liabilities thereunder for the registration of the Notes
or the Exchange Notes.

    The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offer--Conditions." The undersigned
recognizes that as a result of these conditions (which may be waived, in whole
or in part, by ACS), as more particularly set forth in the Prospectus, ACS may
not be required to exchange any of the Notes tendered hereby and, in such event,
the Notes not exchanged will be returned to the undersigned at the address shown
below the signature of the undersigned.

    All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned and every obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned. Tendered Notes may be withdrawn at any time
prior to the Expiration Date.

    Unless otherwise indicated in the box entitled "Special Registration
Instructions" or the box entitled "Special Delivery Instructions" in this Letter
of Transmittal, certificates for all Exchange Notes delivered in exchange for
tendered Notes, and any Notes delivered herewith but not exchanged, will be
registered in the name of the undersigned and shall be delivered to the
undersigned at the address shown below the signature of the undersigned. If an
Exchange Note is to be issued to a person other than the person(s) signing this
Letter of Transmittal, or if an Exchange Note is to be mailed to someone other
than the person(s) signing this Letter of Transmittal or to the person(s)
signing this Letter of Transmittal at an address different than the address
shown on this Letter of Transmittal, the appropriate boxes of this Letter of
Transmittal should be completed. If Notes are surrendered by Holder(s) that have
completed either the box entitled "Special Registration Instructions" or the box
entitled "Special Delivery Instructions" in this Letter of Transmittal,
signature(s) on this Letter of Transmittal must be guaranteed by an Eligible
Institution (defined in Instruction 2).

    Transmittal (or facsimile thereof), together with the Notes (or a
    confirmation of book-entry transfer of such Notes into the Exchange Agent's
    account at the Depository) and any other documents required by the Letter of
    Transmittal, will be deposited by the Eligible Institution with the Exchange
    Agent; and

    three New York Stock Exchange trading days after the Expiration Date.

    Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their Notes according to the guaranteed
delivery procedures set forth above. Any Holder who wishes to tender Notes
pursuant to the guaranteed delivery procedures described above must ensure that
the Exchange Agent receives the Notice of Guaranteed Delivery relating to such
Notes prior to the Expiration Date. Failure to comply with the guaranteed
delivery procedures outlined above will not, of

                                       8

itself, affect the validity or effect a revocation of any Letter of Transmittal
form properly completed and executed by a Holder who attempted to use the
guaranteed delivery procedures.

     3. PARTIAL TENDERS; WITHDRAWALS.  If less than the entire principal amount
of Notes evidenced by a submitted certificate is tendered, the tendering Holder
should fill in the principal amount tendered in the column entitled "Principal
Amount Tendered" in the box entitled "Description of Notes Tendered Hereby." A
newly issued Note for the principal amount of Notes submitted but not tendered
will be sent to such Holder as soon as practicable after the Expiration Date.
All Notes delivered to the Exchange Agent will be deemed to have been tendered
in full unless otherwise indicated.

    Notes tendered pursuant to the Exchange Offer may be withdrawn at any time
prior to the Expiration Date, after which tenders of Notes are irrevocable. To
be effective, a written, telegraphic or facsimile transmission notice of
withdrawal must be timely received by the Exchange Agent. Any such notice of
withdrawal must (i) specify the name of the person having deposited the Notes to
be withdrawn (the "Depositor"), (ii) identify the Notes to be withdrawn
(including the registration number(s) and principal amount of such Notes, or, in
the case of Notes transferred by book-entry transfer, the name and number of the
account at the Depository to be credited), (iii) be signed by the Holder in the
same manner as the original signature on this Letter of Transmittal (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Notes register the transfer
of such Notes into the name of the person withdrawing the tender and (iv)
specify the name in which any such Notes are to be registered, if different from
that of the Depositor. All questions as to the validity, form and eligibility
(including time of receipt) of such notices will be determined by ACS, whose
determination shall be final and binding on all parties. Any Notes so withdrawn
will be deemed not to have been validly tendered for purposes of the Exchange
Offer and no Exchange Notes will be issued with respect thereto unless the Notes
so withdrawn are validly retendered. Any Notes which have been tendered but
which are not accepted for exchange will be returned to the Holder thereof
without cost to such Holder as soon as practicable after withdrawal, rejection
of tender or termination of Exchange Offer.

     4. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
ENDORSEMENTS; GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is signed
by the registered Holder(s) of the Notes tendered hereby, the signature must
correspond with the name(s) as written on the face of the certificates without
alteration or enlargement or any change whatsoever. If this Letter of
Transmittal is signed by a participant in the Depository, the signature must
correspond with the name as it appears on the security position listing as the
owner of the Notes.

    If any of the Notes tendered hereby are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal.

    If a number of notes registered in different names are tendered, it will be
necessary to complete, sign and submit as many separate copies of this Letter of
Transmittal as there are different registrations of Notes.

    Signatures of this Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution unless the Notes
tendered hereby are tendered (i) by a registered Holder who has not completed
the box entitled "Special Registration Instructions" or "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution.

    If this Letter of Transmittal is signed by the registered Holder or Holders
of Notes (which term, for the purposes described herein, shall include a
participant in the Depository whose name appears on a security listing as the
owner of the Notes) listed and tendered hereby, no endorsements of the tendered
Notes or separate written instruments of transfer or exchange are required. In
any other case, the registered Holder (or acting Holder) must either properly
endorse the Notes or transmit properly completed bond powers with this Letter of
Transmittal (in either case, executed exactly as the name(s) of the registered
Holder(s) appear(s) on the Notes, and, with respect to a participant in the
Depository whose

                                       9

name appears on a security position listing as the owner of Notes, exactly as
the name of the participant appears on such security position listing), with the
signature on the Notes or bond power guaranteed by an Eligible Institution
(except where the Notes are tendered for the account of an Eligible
Institution).

    If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by ACS, proper evidence satisfactory
to ACS of their authority so to act must be submitted.

     5. SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.  Tendering Holders
should indicate, in the applicable box, the name and address (or account at the
Depository) in which the Exchange Notes or substitute Notes for principal
amounts not tendered or not accepted for exchange are to be issued (or
deposited), if different from the names and addresses or accounts of the person
signing this Letter of Transmittal. In the case of issuance in a different name,
the employer identification number or social security number of the person named
must also be indicated and the tendering Holder should complete the applicable
box.

    If no instructions are given, the Exchange Notes (and any Notes not tendered
or not accepted) will be issued in the name of and sent to the acting Holder of
the Notes or deposited at such Holder's account at the Depository.

     6. TRANSFER TAXES.  ACS shall pay all transfer taxes, if any, applicable to
the transfer and exchange of Notes to it or its order pursuant to the Exchange
Offer. If a transfer tax is imposed for any reason other than the transfer and
exchange of Notes to ACS or its order pursuant to the Exchange Offer, the amount
of any such transfer taxes (whether imposed on the registered Holder or any
other person) will be payable by the tendering Holder. If satisfactory evidence
of payment of such taxes or exception therefrom is not submitted herewith, the
amount of such transfer taxes will be collected from the tendering Holder by the
Exchange Agent.

    Except as provided in this Instruction 6, it will not be necessary for
transfer stamps to be affixed to the Notes listed in this Letter of Transmittal.

     7. WAIVER OF CONDITIONS.  ACS reserves the right, in its reasonable
judgment, to waive, in whole or in part, any of the conditions to the Exchange
Offer set forth in the Prospectus.

     8. MUTILATED, LOST, STOLEN OR DESTROYED NOTES.  Any Holder whose Notes have
been mutilated, lost, stolen or destroyed should contact the Exchange Agent at
the address indicated above for further instructions.

     9. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating to the
procedure for tendering, as well as requests for additional copies of the
Prospectus and this Letter of Transmittal, may be directed to the Exchange Agent
at the address and telephone number(s) set forth above. In addition, all
questions relating to the Exchange Offer, as well as requests for assistance or
additional copies of the Prospectus and this Letter of Transmittal, may be
directed to Alaska Communications Systems Holdings, Inc., 510 L. Street, Suite
500, Anchorage, Alaska 99501, Attention: Corporate Secretary; telephone (907)
297-3000.

    10. VALIDITY AND FORM.  All questions as to the validity, form, eligibility
(including time of receipt), acceptance of tendered Notes and withdrawal of
tendered Notes will be determined by ACS in its sole discretion, which
determination will be final and binding. ACS reserves the absolute right to
reject any and all Notes not properly tendered or any Notes ACS's acceptance of
which would, in the opinion of counsel for ACS, be unlawful. ACS also reserves
the right, in its reasonable judgment, to waive any defects, irregularities or
conditions of tender as to particular Notes. ACS's interpretation of the terms
and conditions of the Exchange Offer (including the instructions in this Letter
of Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Notes must be cured
within such time as ACS shall determine. Although ACS intends to notify Holders
of defects or

                                       10

irregularities with respect to tenders of Notes, neither ACS, the Exchange Agent
nor any other person shall incur any liability for failure to give such
notification. Tenders of Notes will not be deemed to have been made until such
defects or irregularities have been cured or waived. Any Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering Holder as soon as practicable following the Expiration
Date.

                           IMPORTANT TAX INFORMATION

    Under federal income tax law, a Holder tendering Notes is required to
provide the Exchange Agent with such Holder's correct TIN on Substitute Form W-9
above. If such Holder is an individual, the TIN is the Holder's social security
number. The Certificate of Awaiting Taxpayer Identification Number should be
completed if the tendering Holder has not been issued a TIN and has applied for
a number or intends to apply for a number in the near future. If the Exchange
Agent is not provided with the correct TIN, the Holder may be subject to a $50
penalty imposed by the IRS. In addition, payments that are made to such Holder
with respect to tendered Notes may be subject to backup withholding.

    Certain Holders (including, among others, all domestic corporations and
certain foreign individuals and foreign entities) are not subject to these
backup withholding and reporting requirements. Such a Holder who satisfies one
or more of the conditions set forth in Part 2 of the Substitute Form W-9 should
execute the certification following such Part 2. In order for a foreign Holder
to qualify as an exempt recipient, that Holder must submit to the Exchange Agent
a properly completed IRS Form W-9, signed under penalties of perjury, attesting
to that Holder's exempt status. Such forms can be obtained from the Exchange
Agent.

    If backup withholding applies, the Exchange Agent is required to withhold
31% of any amounts otherwise payable to the Holder. Backup withholding is not an
additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the IRS.

    PURPOSE OF SUBSTITUTE FORM W-9.  To prevent backup withholding on payments
that are made to a Holder with respect to Notes tendered for exchange, the
Holder is required to notify the Exchange Agent of his or her correct TIN by
completing the form herein certifying that the TIN provided on Substitute Form
W-9 is correct (or that such Holder is awaiting a TIN) and that (i) such Holder
is exempt, (ii) such Holder has not been notified by the IRS that he or she is
subject to backup withholding as a result of failure to report all interest or
dividends or (iii) the IRS has notified such Holder that he or she is no longer
subject to backup withholding.

    WHAT NUMBER TO GIVE THE EXCHANGE AGENT.  Each Holder is required to give the
Exchange Agent the social security number or employer identification number of
the record Holder(s) of the Notes. If Notes are in more than one name or are not
in the name of the actual Holder, consult the instructions on IRS Form W-9,
which may be obtained from the Exchange Agent, for additional guidance on which
number to report.

    CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER.  If the tendering
Holder has not been issued a TIN and has applied for a number or intends to
apply for a number in the near future, write "Applied For" in the space for the
TIN on Substitute Form W-9, sign and date the form and the Certificate of
Awaiting Taxpayer Identification Number and return them to the Exchange Agent.
If such certificate is completed and the Exchange Agent is not provided with the
TIN within 60 days, the Exchange Agent will withhold 31% of all payments made
thereafter until a TIN is provided to the Exchange Agent.

    IMPORTANT:  This Letter of Transmittal or a facsimile thereof (together with
Notes or confirmation of book-entry transfer and all other required documents)
or a Notice of Guaranteed Delivery must be received by the Exchange Agent on or
prior to the Expiration Date.

              PLEASE REVIEW INSTRUCTION 11 FOR ADDITIONAL DETAILS.
