Attn::  Mr. Richard Sewell

        RE:  LIMITED WAIVER

             Credit Agreement, dated as of February 25, 2000 (such agreement,
             together with all amendments and restatements, the "Credit
             Agreement"), among American Cellular Corporation (successor by
             merger to ACC Acquisition Co.), as Borrower, Administrative Agent,
             CIBC World Markets Corp. and Barclays Bank PLC as Co-Documentation
             Agents, Lehman Commercial Paper Inc. and TD Securities (USA) Inc.,
             as Co-Syndication Agents, and certain Managing Agents, Co-Agents,
             and Lenders party thereto.

Ladies and Gentlemen:

         Reference is made to the Credit Agreement. Capitalized terms used in
this letter shall have the meanings ascribed to them in the Credit Agreement.

         Borrower's SEC Form 10-K with respect to its fiscal year ended December
31, 2001, contains footnotes to the financial statements describing the likely
need of Borrower in 2002 to reduce Debt of Companies over projected debt levels
in order for Borrower to comply with certain financial covenants in the Credit
Agreement and an opinion of Borrower's auditors that Borrower could violate one
of such covenants (the "DISCLOSURES"). Lenders believe that a reasonable
interpretation of the Disclosures is that Borrower may not be able to satisfy,
because of the Disclosures, Credit Agreement Sections 7.3(c), 7.3(d), 8.6,
9.3(a)(i), and 9.3(a)(ii), each of which is a condition (each, singly a
"CONDITION" and collectively, the "CONDITIONS") to each Borrowing and the
issuance of each LC.

         Credit Agreement Section 9.3(a)(ii) requires delivery to Administrative
Agent not later than 90 days after the last day of each fiscal year of Parent,
of a certificate of the independent certified public accountants who audited
such financial statements stating that "during its audit it obtained no
knowledge of any Default or Potential Default, or if it did obtain such
knowledge, the nature and period of existence thereof...." Borrower did not
deliver to Administrative Agent the certificate required by Credit Agreement
Section 9.3(a)(ii) for Parent's fiscal year ended December 31, 2001, by the date
required for delivery and such failure is a Default under Credit Agreement
Section 10.2(a) (the "CERTIFICATE DEFAULT").

         An interest payment in the amount of $10,522,826.44 was due on April
8, 2002. Borrower has informed Administrative Agent that Borrower will not pay
due to funding limitations all or any portion of such interest payment until the
Effective Date of this letter. Such failure to pay interest within three days
after the due date is a Default under Credit Agreement Section 10.1 (the
"PAYMENT DEFAULT"). The effectiveness of this Waiver is conditioned upon receipt
on the Effective Date by Administrative Agent on behalf of Lenders of payment in
full in immediately available funds of all

<PAGE>

amounts due and payable on April 8, 2002; provided, that if the effectiveness of
this letter (other than satisfaction of the condition precedent of payment of
the amounts specified in this paragraph on the Effective Date) occurs later than
9:30 a.m. (Dallas time) on the Effective Date, such payment shall be paid on the
Business Day immediately following the Effective Date.

         At the request of Borrower and subject to the terms and conditions
hereof, Required Lenders hereby waive (a) each failure to comply with the
Conditions, (b) any Default and Potential Default under Credit Agreement
Sections 10.2 and 10.14 resulting solely from Borrower's failure to satisfy each
Condition, as a condition precedent to each Borrowing and the issuance of each
LC (with respect to both (a) and (b) above, only insofar as such non-compliance
with the Conditions, and any resulting Default or Potential Default under
Sections 10.2 and 10.14, results solely from the Disclosures), (c) the
Certificate Default and (d) the Payment Default (with respect to (d) above, only
if all of the interest payment due on April 8, 2002 is paid in full on or before
the Effective Date).

         The effectiveness of this waiver shall terminate on the earlier of (i)
5:00 p.m. (Dallas time) on May 17, 2002 (the "WAIVER TERMINATION"), (ii) the
occurrence of any Default or Potential Default (other than the failures to
comply with the Conditions and Defaults and Potential Defaults specifically
waived in the preceding paragraph), and (iii) unless otherwise agreed to by
Required Lenders, if the sum of (a) the unpaid principal balance of all
Borrowings under the Revolver Facility (excluding Swing Line Borrowings), plus
(b) the unpaid principal balance of all Swing Line Borrowings, plus (c) all LC
Exposure, exceeds $95,944,580.47. On April 3, 2002, (a) the unpaid principal
balance of all Borrowings under the Revolver Facility (excluding Swing Line
Borrowings) was $69,368,580.47, (b) the unpaid principal balance of all Swing
Line Borrowings was $6,000,000.00, and (c) all LC Exposure was $76,000.00.

         All other terms and provisions of the Credit Agreement and all Loan
Documents remain effective. The parties hereto expressly acknowledge and agree
that the agreements of Required Lenders herein do not constitute a consent to
any other action or inaction by Borrower or any Guarantor, nor a waiver of any
other provision of the Credit Agreement or any other Loan Document.

         Notwithstanding any contrary provision, this letter is not effective
until the date upon which (a) Administrative Agent receives (i) counterparts of
this letter executed by Borrower, each Guarantor, and Required Lenders, (ii)
payment of all reasonable costs, fees, and expenses paid or incurred by
Administrative Agent incident to this letter, (iii) payment of all reasonable
costs, fees, and expenses of Administrative Agent's counsel, Haynes & Boone, LLP
("H&B") and Winstead Sechrest & Minick P.C. ("WSM") incurred through the date of
this letter, and (iv) all amounts described in the fourth paragraph of this
letter; (b) Administrative Agent's counsel, WSM, receives a deposit in the
amount of $200,000; and (c) WSM's advisor, Ernst & Young Corporate Finance LLC
("EYCF"), receives a deposit in the amount of $200,000. On the Business Day upon
which all of the preceding conditions precedent are satisfied (the "EFFECTIVE
DATE"), this letter shall be effective as of March 29, 2002.

         Borrower acknowledges and agrees that from and after the Effective Date
(and notwithstanding the occurrence of the Waiver Termination or other
termination of this letter):

                                       2

<PAGE>

                 (a) Borrower shall, in accordance with Credit Agreement Section
         9.4, cooperate with EYCF;

                 (b) Borrower shall, in accordance with Credit Agreement
         Sections 11.11 and 11.12, pay all reasonable fees and expenses of H&B,
         WSM, and EYCF; and

                 (c) each request for a Swing Line Borrowing shall constitute
         the representation and warranty by Borrower that each of the matters
         (except only those matters expressly waived pursuant to this letter and
         only for so long as such matters are waived pursuant to this letter) in
         Credit Agreement Sections 7.3(c) through (h) are true and correct on
         the date of request for such Swing Line Borrowing and after giving
         effect to such Swing Line Borrowing.

         As a material inducement to Administrative Agent and Lenders to execute
and deliver this letter, Borrower and each Guarantor (a) consent to the
agreements in this letter, (b) agree and acknowledge that (i) the execution,
delivery, and performance of this letter shall in no way release, diminish,
impair, reduce, or otherwise affect the respective obligations of Borrower or
Guarantors under their respective Loan Documents, which Loan Documents shall
remain in full force and effect, and all Liens, guaranties, and Rights
thereunder are hereby ratified and confirmed, and (ii) nothing in this letter is
intended as or shall be construed as a waiver of any Right of Administrative
Agent or any Lender pursuant to any Affiliate Subordination Agreement or any
other agreement purporting to subordinate any Debt, Lien, or Right of any Person
to the Obligation and the Rights of Administrative Agent and Lenders, and (c)
VOLUNTARILY AND KNOWINGLY RELEASE AND FOREVER DISCHARGE EACH LENDER AND
ADMINISTRATIVE AGENT ANT) THEIR RESPECTIVE PREDECESSORS, OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, SUCCESSORS AND ASSIGNS (EACH, A "RELEASED PARTY"), FROM ALL
POSSIBLE CLAIMS, DEMANDS, ACTIONS, CAUSES OF ACTION, DAMAGES, COSTS, EXPENSES,
AND LIABILITIES WHATSOEVER, KNOWN OR UNKNOWN, ANTICIPATED OR UNANTICIPATED,
SUSPECTED OR UNSUSPECTED, FIXED, CONTINGENT, OR CONDITIONAL, AT LAW OR IN
EQUITY, ARISING ON OR BEFORE THE DATE THIS AGREEMENT IS EXECUTED OR THE
EFFECTIVE DATE, WHICH BORROWER OR ANY GUARANTOR MAY NOW HAVE AGAINST ANY
RELEASED PARTY, IF ANY, AND IRRESPECTIVE OF WHETHER ANY SUCH CLAIMS ARISE OUT OF
CONTRACT, TORT, VIOLATION OF LAW OR REGULATIONS, OR OTHERWISE, AND ARISING FROM
ANY "OBLIGATIONS", INCLUDING, WITHOUT LIMITATION, ANY CONTRACTING FOR, CHARGING,
TAKING, RESERVING, COLLECTING OR RECEIVING INTEREST IN EXCESS OF THE HIGHEST
LAWFUL RATE APPLICABLE, THE EXERCISE OF ANY RIGHTS AND REMEDIES UNDER THE CREDIT
AGREEMENT OR OTHER LOAN DOCUMENTS, AND NEGOTIATION FOR AND EXECUTION OF THIS
LETTER.

of a counterpart of this letter in the space provided below. This letter may be
executed in any number of counterparts, all of which taken together shall
constitute one and the same instrument. In making proof hereof, it shall not be
