                      WHERE YOU CAN FIND MORE INFORMATION
 
      We have filed with the SEC a Registration Statement on Form S-4 under the
Securities Act concerning the new notes being offered. The SEC's rules and
regulations allow us to omit from this prospectus some of the information
contained in the registration statement. For further information concerning
Centennial Cellular Corp. and the notes being offered, we refer you to the
registration statement and the documents filed as exhibits to the registration
statement.
 
      Centennial Cellular Corp. also files annual, quarterly and special
reports, proxy and information statements and other information with the SEC.
You may read and copy any document we file with the Commission, including the
Registration Statement, at the SEC's public reference room at Judiciary Plaza,
450 Fifth Street, N.W., Washington, D.C. 20549, and at the SEC's web site
(http://www.sec.gov). You may also request copies of such documents, upon
payment of a duplicating fee, by writing to the SEC at 450 Fifth Street, N.W.,
Washington, D.C. 20549. Centennial's common stock is listed on the Nasdaq
National Market. You may read reports and other information filed by Centennial
with the Nasdaq National Market at the offices of the National Association of
Securities Dealers, Inc., 1735 K Street, N.W., Washington, D.C. 20006.
 
      Centennial Cellular Operating Co. LLC is a wholly-owned subsidiary of
Centennial. Because of this relationship and because the new notes are co-
issued by Centennial and Centennial Cellular Operating, we expect to receive
advice from the SEC's staff that Centennial Cellular Operating will not have to
comply as a separate registrant with the periodic reporting and other
informational requirements of the Securities Exchange Act of 1934.
 
      This prospectus incorporates important business and financial information
about Centennial and Centennial Cellular Operating that is not included in, or
delivered with, the prospectus. This information

                           FORWARD-LOOKING STATEMENTS
 
      This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties and assumptions about us, including, among other things:
 
   .  Our high degree of leverage and the requirement for significant and
      sustained growth in our cash flow to meet our debt service
      requirements,
 
   .  That we are a holding company and the notes are structurally
      subordinated to all indebtedness of our subsidiaries, including
      guarantees by our subsidiaries of all indebtedness under our $1.05
 
                                       3
<PAGE>
 
      billion credit facility (approximately $936 million of which was drawn
      at closing of the merger and a portion of which was borrowed directly
      by our Puerto Rico subsidiary),
 
   .  Our history of net losses and the expectation of future losses,
 
   .  That the telecommunications industry is highly competitive,
 
   .  That new technologies or new business opportunities will require
      additional investments in network capacity or additional capital
      spending,
 
   .  That the success of any acquisitions will depend on our ability to
      integrate acquired businesses,
 
   .  That the telecommunications industry is subject to rapid and
      significant changes in technology,
 
   .  That there is potential for adverse regulatory change and the need for
      regulatory approvals in the operation of our business and renewal of
      our cellular licenses,
 
   .  Fluctuations in market value of our licenses,
 
   .  Risks associated with the regional economic conditions in the areas we
      operate our business,
 
   .  Operating costs due to fraud,
 
   .  That a decline in roaming rates may materially adversely affect us,
 
   .  That a dispute regarding reverse billing may materially adversely
      affect us,
 
   .  That the indenture governing the notes will require us to offer to
      purchase all of the notes issued and outstanding upon any change of
      control and that the credit facility contains similar provisions,
      which purchases, in each case, we may not have sufficient funds to
      consummate,
 
   .  That the indenture and the credit facility impose significant
      operating and financial restrictions on Centennial Cellular Operating,
 
   .  That Centennial Cellular Operating has pledged the capital stock of
      all its direct and indirect subsidiaries to the lenders under the
      credit facility and that all of the assets of such subsidiaries are
      pledged to such lenders,
 
   .  That Centennial has unconditionally guaranteed the obligations of the
      borrowers under the credit facility,
 
   .  That Centennial, as co-obligor, has no assets other than the stock of
      Centennial Cellular Operating and Centennial is not subject to the
      covenants contained in the indenture governing the notes,
 
   .  That the right of the trustee under the indenture and a pledge and
      escrow agreement to obtain payment on the notes upon the occurrence of
      an event of default may be significantly impaired by applicable
      bankruptcy law,
 
   .  The lack of certainty with respect to how a court might decide a suit
      by an unpaid creditor on the basis of fraudulent conveyance,
 
                                       4
<PAGE>
 
   .  The potential effect of Year 2000 computer issues,
 
   .  Risks associated with new management and any future changes in
      management,
 
   .  That certain equity investors control Centennial and its subsidiaries
      and have the power to elect directors and take other corporate
      actions,
 
   .  That we have limited ability to direct the operations of the systems
      in which we hold minority cellular investment interests as a limited
      partner and that our interests in such systems may be diluted if we do
      not meet a capital call,
 
   .  The potential effect of equipment failure or natural disaster on our
      business,
 
   .  Concerns about radio frequency emissions from cellular handsets, and
 
   .  The absence of a public market for the new notes.
 
      We are not obligated to update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise. In light of
these risks, uncertainties and assumptions, the forward-looking events
discussed in this prospectus might not occur.
 
                                 CERTAIN TERMS
 
      Interests in cellular markets that are licensed by the Federal
Communications Commission are commonly measured on the basis of the population
of the market served, with each person in the market area referred to as a
"Pop." The number of Pops or Net Pops owned is not necessarily indicative of
the number of subscribers or potential subscribers. As used in this prospectus,
unless otherwise indicated, the term "Pops" means the estimate of the 1996
population of a metropolitan statistical area or rural service area, as derived
from the 1997 Paul Kagan Associates population estimates. The term "Net Pops"
means the estimated population with respect to a given service area multiplied
by the percentage interest that a company owns in the entity licensed in such
service area. Metropolitan statistical areas and rural service areas are also
referred to as "markets." The term "wireline" license refers to the license for
any market initially awarded to a company or group that was affiliated with a
local landline telephone carrier in the market. The term "non-wireline" license
refers to the license for any market that was initially awarded to a company,
individual or group not affiliated with any landline carrier.

                           SUMMARY OF THE PROSPECTUS
 
      The following summary contains a general discussion of our businesses,
the offering and summary financial information. We encourage you to read this
entire prospectus for a more complete understanding of Centennial, Centennial
Cellular Operating and the exchange offer. Centennial Cellular Operating became
a wholly-owned subsidiary of Centennial on January 7, 1999. In this prospectus,
we refer to the business operations of our domestic rural cellular systems as
"Centennial Rural Cellular." Likewise, "Centennial de Puerto Rico" refers to
our Puerto Rico business operations. See "Certain Terms" for definitions of
industry terms used and "Selected Financial and Operating Information" for
operating and financial definitions. Investors should carefully consider the
information set forth under the heading "Risk Factors." In addition, certain
statements include forward-looking statements which involve risks and
uncertainties. See "Forward-Looking Statements."
 
                           Centennial Cellular Corp.
 
      Our company is one of the largest independent wireless telecommunications
service providers in the United States and Puerto Rico with approximately 10.8
million Net Pops and 426,700 subscribers as of February 28, 1999. Centennial
Rural Cellular serves 5.8 million Net Pops and its service area covers
approximately 81,645 square miles. Our subsidiary, Centennial de Puerto Rico,
is a fully integrated provider of communications services in Puerto Rico. These
operations utilize a personal communications services license that covers 3.8
million Pops in Puerto Rico and the U.S. Virgin Islands and a competitive local
exchange carrier license to operate in Puerto Rico. In addition, we own
minority shares, representing approximately 1.2 million Net Pops, in certain
other cellular operations controlled and managed by other cellular operators.
 
      The table below shows certain data for each of our two principal business
segments.

                   Summary of Ability to Resell the New Notes
 
      We believe that the new notes issued in the exchange offer may be offered
for resale, resold or otherwise transferred by you without compliance with the
registration and prospectus delivery provisions of the Securities Act, but only
if:
 
     .  you acquire the new notes in the ordinary course of business,
 
     .  you are not participating, do not intend to participate and have no
        arrangement or understanding with any person to participate in a
        distribution of the new notes, and
 
     .  you are not an affiliate of ours, as the term affiliate is defined
        in Rule 405 under the Securities Act and which may include our
        executive officers and directors, another person having control over
        our operations or management or an entity we control.
 
      By executing and delivering the letter of transmittal, you will represent
to us that the above statements by you are true.
 
      Each broker-dealer that is issued new notes in the exchange offer for its
own account in exchange for outstanding notes which were acquired by the
broker-dealer as a result of market-making or other trading activities, must
acknowledge that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of the new notes. A broker-dealer
may use this prospectus, as it may be amended or supplemented from time to
time, for an offer to resell, resale or similar transfer of the new notes
issued to it in the exchange offer.
 
                      Summary Description of the New Notes
 
Notes Offered
 
      We are offering $370.0 million aggregate principal amount of 10 3/4%
Senior Subordinated Notes due 2008. The form and terms of the new notes will be
the same as the form and terms of the outstanding notes except that:
 
     .  the new notes will bear a different CUSP number from the outstanding
        notes,
 
     .  the new notes will have been registered under the Securities Act
        and, therefore, will not bear legends restricting their transfer,
        and
 
     .  you will not be entitled to any exchange or registration rights with
        respect to the new notes.
 
      The new notes will evidence the same debt as the outstanding notes, will
be entitled to the benefits of the indenture governing the outstanding notes
and will be treated under the indenture as a single class with the outstanding
notes.
 
Issuers
 
      Centennial Cellular and its wholly owned subsidiary, Centennial Cellular
Operating.
 
Maturity
 
      December 15, 2008.
 
                                       9

Interest Payment Dates
 
     We will pay interest on the notes on June 15 and December 15 of each year,
beginning June 15, 1999.
 
Ranking
 
     The notes are subordinated to all our senior debt, including all our debt
under a credit facility with Merrill Lynch Capital Corporation, Nations Bank
N.A., The Chase Manhattan Bank, The Bank of Nova Scotia, Morgan Stanley Senior
Funding, Inc. and other financial institutions party to the credit facility.
The notes rank equally with any senior subordinated debt, and rank senior to
all our subordinated debt. The notes effectively rank junior to all liabilities
of the subsidiaries of Centennial Cellular Operating including debt under the
credit facility.
 
     On February 28, 1999, the notes:
 
     . were subordinated to $933.9 million of senior debt under the credit
       facility, and
 
     . were effectively ranked junior to the guarantees of $933.9 million of
       this debt by the subsidiaries of Centennial Cellular Operating, other
       than a portion of such debt that was borrowed directly by Centennial
       de Puerto Rico, which has not initially guaranteed this debt.
 
     The notes were senior to $180 million (face amount) of subordinated notes
issued to WCAS Capital Partners III, L.P. The only debt of Centennial (without
its subsidiaries) as of February 28, 1999 were these subordinated notes,
Centennial's guarantee under the credit facility and the notes for which the
exchange offer is being made.
 
Security
 
     At the time the outstanding notes were issued, we used a portion of the
proceeds to purchase a portfolio of government securities in an amount
sufficient to pay the first three interest payments on the notes. We pledged
this portfolio of securities for your benefit and the benefit of other holders
of the notes. The notes are otherwise unsecured. You should also read the
section captioned "Description of the New Notes" under the heading "Security."
 
Optional Redemption
 
     We may redeem any of the notes on or after December 15, 2003 at the
redemption prices set forth in the "Description of the New Notes" section under
the heading "Optional Redemption."
 
     Prior to December 15, 2001, we may redeem up to 35% of the aggregate
principal amount of the then outstanding notes with the net proceeds of one or
more public equity offerings or strategic equity offerings at 110.75% of their
principal amount, plus accrued interest.
 
Change of Control
 
     If we experience specific kinds of changes in control, we must offer to
repurchase any then-outstanding notes at 101% of their principal amount, plus
accrued interest, if any, to the date of repurchase.

Covenants
 
      The indenture governing the notes contains covenants that, among other
things, limit our ability and the ability of our restricted subsidiaries to:
 
     .  incur additional indebtedness,
 
     .  pay dividends on, redeem or repurchase our capital stock,
 
     .  make investments,
 
     .  restrict dividend or other payments to us,
 
     .  engage in transactions with related persons,
 
     .  guarantee indebtedness,
 
     .  sell assets,
 
     .  create certain liens,
 
     .  consolidate, merge or transfer all or substantially all of our
        assets and the assets of our subsidiaries on a consolidated basis,
        and
 
     .  enter new lines of business.
 
      These covenants are subject to important exceptions and qualifications,
which are described under the heading "Description of the New Notes--Certain
Covenants" in this Prospectus.
 
                                   The Merger
 
      Merger Agreement. On January 7, 1999, Centennial merged with CCW
Acquisition Corp., a new Delaware corporation organized by Welsh, Carson,
Anderson & Stowe VIII, L.P., pursuant to a merger agreement dated as of July 2,
1998. At the effective time of the merger, by virtue of the merger,
 
     .  each outstanding share of Class A Common Stock of Centennial was
        converted into the right to receive, pursuant to each holder's
        election and subject to proration, either (a) one common share of
        the surviving corporation or (b) $41.50 in cash;
 
     .  each outstanding share of Class B Common Stock of Centennial was
        converted into the right to receive $41.50 in cash; and
 
     .  all shares of Convertible Preferred Stock and Second Series
        Convertible Preferred Stock of Centennial were converted into the
        right to receive an amount of cash as if such shares had been
        converted in common shares of Centennial.
 
      The surviving corporation in the merger continues to operate under the
name "Centennial Cellular Corp." The merger was accounted for as a
recapitalization in which the historical basis of our company's assets and
liabilities was not affected and no new goodwill related to the merger was
created.

Sources and Uses of Funds
 
      The equity investors in CCW Acquisition Corp. financed the merger of CCW
Acquisition Corp. into Centennial from a variety of sources, including a credit
facility, an offering of subordinated notes, equity contributions and the
outstanding notes for which we are making an exchange offer. The funds were
used to pay cash merger consideration to stockholders of Centennial, to
refinance its existing debt and to pay the fees and expenses of the merger and
related transactions. For a more complete description of the sources and uses
of funds in connection with the merger, you should read the section captioned
"The Merger" under the heading "Financing of the Merger" as well as the section

                    Summary Historical Financial Information
 
      The following table sets forth summary historical consolidated financial
information for Centennial as of February 28, 1999 and 1998 and for the nine
months ended February 28, 1999 and 1998. Such data were derived from our
unaudited condensed consolidated financial statements and notes, but, in the
opinion of our management, include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the financial
position and results of operations for such periods. Operating results for the
nine months ended February 28, 1999 and 1998 do not necessarily show what the
results for a full year may be. The table also sets forth summary historical
consolidated financial information for Centennial for the five years ended May
31, 1998. Such data were derived from our audited consolidated financial
statements and notes. Since the information in this table is only a summary,

    recapitalization costs, extraordinary loss on early extinguishment of debt
    and gain on sale of assets. EBITDA is presented because it is a widely
    accepted financial indicator of a company's ability to service and/or incur
    indebtedness. EBITDA should not be considered an alternative to net income
    as a measure of our operating results or to cash flow as a measure of
    liquidity. In addition, although the EBITDA measure of performance is not
    recognized under generally accepted accounting principles, it is widely
    used by various companies as a general measure of a company's performance
    because it assists in comparing performance on a relatively consistent
    basis across companies without regard to depreciation and amortization,
    which can vary significantly depending on accounting methods (particularly
    where acquisitions are involved) or non-operating factors such as
    historical cost bases. Because EBITDA is not calculated identically by all
    companies, the presentation herein may not be strictly comparable to other
    similarly titled measures of other companies.

                                  RISK FACTORS
 
      You should carefully consider the following factors and other information
in this prospectus before deciding to exchange outstanding notes for new notes.
Any of the following risks could have a material adverse impact on our
business, financial condition or results of operations or on the value of the
notes.
 
Significant Indebtedness--Our debt service consumes a substantial portion of
the cash we generate and reduces the cash available to invest in our
operations.
 
      We have a significant amount of indebtedness after the merger. Our large
amount of debt could significantly affect our business and you because, among
other things, it:
 
     .  limits our ability to obtain additional financing for future
        acquisitions (if any), working capital, capital expenditures or
        other purposes;
 
     .  limits our ability to use operating cash flow in other areas of our
        business because we must dedicate a substantial portion of these
        funds to make principal payments and fund debt service;
 
     .  increases our vulnerability to adverse economic and industry
        conditions;
 
     .  increases our vulnerability to interest rate increases because
        borrowings under our credit facility are at variable interest rates;
        and
 
     .  increases our vulnerability to competitive pressures, as many of our
        competitors will be less leveraged than we are.
 
      As of February 28, 1999:
 
     .  We had outstanding total long-term indebtedness of approximately
        $1.46 billion, and
 
     .  Centennial (without its subsidiaries) had $180 million (face amount)
        of long-term indebtedness (other than its guarantee under the credit
        facility and its co-obligation under the outstanding notes).
 
      Following the financings related to the merger, our total long-term
indebtedness was substantially greater than our long-term indebtedness before
the merger. In addition, the indenture governing the outstanding notes and our
other debt instruments allows us to incur additional indebtedness, including
secured indebtedness. As of February 28, 1999 Centennial Cellular Operating had
an aggregate of $116.1 million available for borrowing under the credit
facility.
 
Ability to Service Debt--In order to service our debt, we require a significant
amount of cash. However, our ability to generate cash depends on many factors
that are beyond our control.
 
      Prevailing economic conditions and financial, business and other factors,
many of which are beyond our control, will affect our ability to pay interest
on the notes and satisfy our other debt obligations. Upon the issuance of the
notes, our consolidated interest expense has increased compared to prior years.
We currently believe that our cash flow, together with available borrowings
under the credit facility, will permit us to pay our operating expenses and
service our debts for the foreseeable future. Our belief is based on
significant assumptions, including, among other things, that we will succeed in
implementing our business strategy and that there will be no material adverse
developments in our business, liquidity or capital requirements. If, in the
future, we cannot generate sufficient cash from operations to make scheduled
payments on the notes or to meet our other obligations, we will need to
refinance, obtain additional financing or sell assets. We cannot assure you
that our business will generate cash flow, or that we will be able to obtain
funding sufficient to satisfy our debt service requirements. On a pro forma
basis, earnings were insufficient to cover fixed charges for Centennial and
 
                                       17
<PAGE>
 
Centennial Cellular Operating by $161.8 million and $138.9 million for the year
ended May 31, 1998, and by $64.7 million and $48.2 million for the nine months
ended February 28, 1999.
 
Restrictions Imposed on Us by Our Debt Instruments--Our existing debt
instruments contain restrictions and limitations which could significantly
affect our ability to operate our business and repay the notes.
 
      We and our subsidiaries are subject to significant operating and
financial restrictions contained in the instruments governing the notes and our
credit facility. Such restrictions affect, and in many respects significantly
limit or prohibit, among other things, our ability to:
 
     .  borrow more funds,
     .  pay dividends,
 
     .  repay indebtedness prior to stated maturities,
 
     .  sell assets,
     .  make investments,
 
     .  engage in transactions with stockholders and affiliates,
 
     .  create liens, or
 
     .  engage in mergers or acquisitions.
 
      In addition, the credit facility requires us to maintain certain
financial ratios. These restrictions could also limit our ability to obtain
financing in the future, make needed capital expenditures, withstand a future
downturn in our business or the economy in general or in our specific areas of
coverage, or otherwise conduct necessary corporate activities. If we or our
subsidiaries fail to comply with these restrictions, we may be in default under
the terms of such indebtedness, even if we are otherwise able to meet our debt
service obligations. In the event of a default, the holders of such
indebtedness could elect to declare all such indebtedness, together with
accrued interest, to be due and payable and a significant portion of our other
indebtedness (including the notes) and that of our subsidiaries may become
immediately due and payable. We cannot assure you that we or our subsidiaries
would be able to make such payments or borrow sufficient funds from alternative
sources to make any such payment. Even if we were to obtain additional
financing, such financing may be on terms unfavorable to us.
 
Subordination of the Notes--Because the notes rank below our senior debt and
below all debt of our subsidiaries, you may not receive full payment on your
notes.
 
      The notes are subordinated to all our senior indebtedness. In addition,
the notes effectively rank junior to all liabilities of our subsidiaries. As of
February 28, 1999 Centennial Cellular Operating had outstanding $933.9 million
of senior indebtedness and $370 million of senior subordinated indebtedness. As
of February 28, 1999,
 
     .  Centennial Cellular Corp. (without its subsidiaries) had no
        indebtedness outstanding other than $180 million (face amount) of
        subordinated notes issued to WCAS Capital Partners III, L.P., and
        its guarantee of $933.9 million of Centennial Cellular Operating's
        indebtedness under the Credit Facility and its co-obligation on the
        notes and
 
     .  our subsidiaries had no indebtedness outstanding other than their
        guarantees of $933.9 million of funded indebtedness under the Credit
        Facility (a portion of which was borrowed directly by Centennial de
        Puerto Rico, which indebtedness is effectively senior to the notes).
 
                                       18
<PAGE>
 
We also may incur additional senior indebtedness and our subsidiaries may incur
additional indebtedness consistent with the terms of our debt agreements. For
example, upon consummation of the offering of the notes and our use of the net
proceeds received from that offering, as of February 28, 1999, we had $116.1
million available under our credit facility which, if borrowed, would be senior
indebtedness and would be guaranteed by our subsidiaries other than Centennial
de Puerto Rico and its subsidiaries. In the event of our bankruptcy,
liquidation or dissolution, our assets would be available to pay obligations on
the notes only after all payments had been made on our senior indebtedness. We
cannot assure you that sufficient assets will remain to make any payments on
the notes. In addition, certain events of default under our senior indebtedness
would prohibit us from making any payments on the notes. The term "senior
indebtedness" is defined in the "Description of the New Notes--Subordination"
section of this prospectus.
 
Restrictions on Subsidiary Dividends--Because our subsidiaries may not be
permitted to pay dividends to us, we may not be able to repay the notes.
 
      Our company depends on the cash flow from our subsidiaries to meet our
obligations, including all payments on the notes. Accordingly, our ability to
make payments to holders of the notes depends on the receipt of sufficient
funds from our subsidiaries. Because of the terms of existing and future
indebtedness of our subsidiaries, including the credit facility, which is
initially secured by the assets of our domestic subsidiaries, we may be
restricted in receiving funds from our subsidiaries. The indenture for the
notes permits our subsidiaries to enter into agreements which restrict
dividends and distributions to us. See "Description of the New Notes--Certain
Covenants--Limitation on Restrictions on Subsidiary Dividends."
 
Lack of Security--Because the notes are unsecured, other lenders will have
prior claims to our assets in the event we became insolvent or are liquidated.
 
      In addition to being subordinate to all of our senior indebtedness, the
notes are not secured by any of our assets, other than the funds pledged to pay
the first three interest payments. Our obligations under our credit facility
are secured by substantially all of our assets, including assets held by our
subsidiaries. Under the indenture for the notes, we and our subsidiaries are
permitted to incur additional secured indebtedness. If we became insolvent or
are liquidated, or if payment under our credit facility is accelerated, the
lenders under our credit facility would be entitled to exercise the remedies
available to a secured lender under applicable law. Therefore, our bank lenders
will have a claim on such assets before the holders of the notes. Because the
notes are unsecured, there may be no assets remaining for the holders of notes
or any assets may be insufficient to pay off the notes. See "Description of
Certain Indebtedness."
 
Net Losses--We have a history of net losses which we expect to continue through
the foreseeable future.
 
      Since our formation, we have concentrated on the acquisition, exchange,
construction, initial operation and development of cellular telephone systems
in our domestic markets and the provision of facilities-based integrated
communications in Puerto Rico. Our business operations have incurred net losses
for each of the past five fiscal years and, after giving pro forma effect to
the offering of the outstanding notes and borrowings under the credit facility,
Centennial Cellular Operating would have incurred a net loss of $120.5 million
for the fiscal year ended May 31, 1998. We expect to report net losses for the
foreseeable future due to increased interest payments and non-cash charges such
as depreciation and amortization. We cannot assure you that in future periods
our operations will generate sufficient earnings to pay our obligations,
including the notes.
 
Competition in Rural Cellular Markets--Because the wireless telephone service
industry is highly competitive, we may be adversely affected by competitors
with superior financial resources and/or technology.
 
      Our principal business, wireless telephone service, is highly
competitive. Competition for wireless telephone service in each of our markets
is based primarily on the quality of service, price, system coverage,
 
                                       19
<PAGE>
 
enhancements offered, capacity and customer service. We compete with one
cellular licensee in each geographic area and most of these competitors are
larger, have greater financial resources than we do and may be less leveraged
than we are. We also face competition from paging companies, landline telephone
companies and resellers. The FCC requires cellular and personal communication
services licensees to offer service to resellers on a nondiscriminatory basis.
A reseller buys blocks of telephone numbers from cellular and personal
communication services providers, usually at a discounted rate, and resells the
service to the public for a profit. Many telecommunications companies resell
wireless telephone service as a complement to other services, such as long
distance or local telephone services.
 
      As a result of recent regulatory and legislative initiatives, we also
face increased competition from entities using or proposing to use other
comparable communications technologies. The FCC currently is licensing
commercial personal communication services. The FCC identified two categories
of personal communication services: broadband and narrowband. Personal
communication services is not a specific technology, but a variety of potential
technologies that could compete with cellular telephone systems. For example,
the broadband personal communication services systems licensed to operate in
the 2 GHz band may provide wireless two-way telecommunications services for
voice, data, graphic and other transmissions. Equipment used for broadband
personal communication services includes small, lightweight and wireless
telephone handsets, computers that can communicate over the airwaves wherever
they are located, and portable facsimile machines and other graphic devices.
Many personal communication services systems have commenced operations in the
last few years. When a personal communication services system employs microcell
technology, as is common, it uses a network of small, low-powered transceivers
placed throughout a neighborhood, business complex, community or metropolitan
area to provide customers with mobile and portable voice and data
communications. Many personal communication services licensees who will compete
with us have access to substantial capital resources. In addition, many of
these companies, or their affiliates, already operate large cellular telephone
systems and thus bring significant wireless experience to this new marketplace.
To date, we have experienced little impact from personal communication services
competition in our domestic markets. However, there can be no assurance of the
long-term effect these new personal communication services licensees may have
on us.
 
      ESMR is a two-way wireless communications service that incorporates
characteristics of cellular technology, including many low-power transmitters
and connection with the landline telephone network. ESMR service may compete
with cellular service by providing digital communication technology, lower
rates, enhanced privacy and additional features such as electronic mail and
built-in paging. Nextel Communications, Inc. is the primary provider of such
services today.
 
      We may also face competition from satellite-based services. The FCC has
issued a number of licenses to provide such services which would enable
subscribers to access mobile communications systems throughout the world.
Additional proposals for the provision of satellite services remain pending
with the FCC and foreign regulatory bodies must approve certain aspects of some
satellite systems. Although we may experience increased competition from such
services in the future, such systems have not affected our operations to date.
 
      The FCC has made available other frequency bands that may be used for the
provision of cellular-like services. The general wireless communications
service and the wireless communications service are two such services that are
in their infancy. Although the FCC has proposed technical rules for wireless
communications service that will make commercial mobile services like cellular
and personal communication services infeasible, there can be no assurance that
the FCC will not adopt more flexible wireless communications service technical
rules that will enable wireless communications service licensees to provide
service comparable to cellular and personal communication services.
 
      We are unable to predict whether such competing technologies or any new
technologies will be successful and, if successful, whether any will provide
significant competition for us. We cannot assure you that one or more of the
technologies that we currently use in our business will not become inferior or
obsolete at some time in the future.

Competition in Puerto Rico Market--We may be adversely affected by competition
from other wireless and wireline telephone service providers in Puerto Rico.
 
Competition from Cellular Systems
 
      The market for wireless services is highly competitive in Puerto Rico.
Our two main competitors for wireless services in the Puerto Rico market are
Cellular Communications of Puerto Rico, Inc., a publicly traded U.S. company
which has agreed to be acquired by SBC Communications, Inc., a U.S.
telecommunications company, and Telephonos de Mexico, S.A., a Mexican
telecommunications company, and the Puerto Rico Telephone Company, of which a
majority is owned by GTE Corporation, a U.S. telecommunications company, and a
minority is owned by the Commonwealth of Puerto Rico. The parties' public
statements indicate that they expect the transaction to close during the first
quarter of 1999. In July 1998, GTE agreed to merge with Bell Atlantic
Corporation. Both CoreComm and the Puerto Rico Telephone Company were earlier
entrants into the Puerto Rico wireless market, have greater resources than we
do and currently hold subscriber market shares of approximately 47% and 40%,
respectively. CoreComm and the Puerto Rico Telephone Company offer both analog
and digital cellular service to their subscribers and offer more capability of
cellular service than us to their customers traveling outside Puerto Rico. We
currently offer customers in Puerto Rico the capability of cellular service in
the U.S. pursuant to an agreement with Sprint.
 
Competition From Other Broadband Personal Communication Services Systems
 
      The FCC has issued a 30 MHz broadband personal communication services
license for the Puerto Rico-U.S. Virgin Islands metropolitan trading area to
TeleCorp. The FCC has also issued four broadband personal communication
services licenses for the San Juan, Puerto Rico basic trading area, the
Mayaguez-Aguadilla-Ponce, Puerto Rico basic trading area and the U.S. Virgin
Islands basic trading area to other entities, including a 10 MHz license to the
Puerto Rico Telephone Company. If these licenses become operational, these
broadband personal communication services systems will present additional
competition to our personal communication services operations in Puerto Rico.
We believe that TeleCorp, which is in the process of constructing its personal
communication services system as part of a franchise relationship with AT&T
Wireless Services, will likely begin service within the next twelve months.
 
      New personal communication services competitors will face a number of
significant hurdles in building out their systems in Puerto Rico, including the
development of a network connecting its cell sites. A competitor may:
 
     .  use the Puerto Rico Telephone Company's network,
 
     .  construct its own network,
 
     .  use our fiber optic network, or
 
     .  choose a combination of these methods. We believe that few
        competitors will choose to build their own networks because of the
        significant cost and time constraints, nor will they choose to
        contract with the Puerto Rico Telephone Company's because of its
        poor reliability and the long wait times required for these new
        services to be added. Thus, we believe that some of our competitors
        in Puerto Rico may seek to contract with us for these services.
 
Competition From Resellers
 
      The FCC requires all cellular and personal communication system operators
to provide service on a nondiscriminatory basis to resellers, who provide
service to customers but do not hold an FCC license or own facilities to
provide such services. Instead, a reseller buys blocks of cellular telephone
numbers from a licensed carrier, usually at a discounted rate, and resells
service to the public. Thus, a reseller may be both a customer of a cellular or
personal communications services provider and also a competitor. Ameritel,
acting as a reseller,
 
                                       21
<PAGE>
 
is currently offering cellular services at Radio Shack stores throughout Puerto
Rico. We do not know of any other significant cellular resellers currently
operating in competition with our personal communication services system.
 
Wireline Competition
 
      Our primary competitor for wireline service is the incumbent provider,
the Puerto Rico Telephone Company, which has considerably greater resources
than we do. GTE has bought a majority stake in the Puerto Rico Telephone
Company and controls the Puerto Rico Telephone Company's board of directors.
GTE also has significantly greater resources than we do and may make changes to
improve service which in turn may strengthen the Puerto Rico Telephone
Company's competitive position. The growth of our market presence will depend
upon our ability to obtain customers that are underserved by the PRTC (or its
successor) or looking for an alternative. Because of our ability to provide
more timely installation and service to date, we have primarily attracted
customers on the basis of quality and service rather than price. KMS, a U.S.
corporation based in New Jersey, has announced plans to set up a fiber optic
network in Puerto Rico to offer internet access and data transmission, although
it has not yet commenced construction.
 
Risks Associated With Acquisitions--Our strategy to expand our business through
acquisitions may fail due to a number of risks involved in implementing this
strategy.
 
      Since August 1988, we have acquired 29 cellular systems in the United
States that we own and manage. We intend to expand our current clusters through
the acquisition of properties and target for purchase other small to mid-sized
metropolitan service areas and strategic rural service areas that we believe
are undervalued or underdeveloped or that possess traits that indicate high
potential cellular use and superior financial performance. There can be no
assurance, however, that we will seek to acquire or be successful in acquiring
any of these systems. Increased competition for acquisition candidates could
result in fewer acquisition opportunities for us and higher acquisition prices.
The magnitude, timing and nature of future acquisitions will depend upon
various factors, including the availability of suitable acquisition candidates,
competition with other telecommunications companies for suitable acquisitions,
the negotiation of acceptable terms, our financial capabilities, the
availability of skilled employees to manage the acquired companies and general
economic and business conditions.
 
      We face risks that the systems we own and those we acquire in the future
will not perform as expected and that such systems will not generate the
returns necessary to repay the indebtedness incurred to acquire, or fund the
capital expenditures needed to develop, the systems. In addition, expansion of
our operations may place a significant strain on our management, financial and
other resources. Our ability to manage future growth will depend upon our
ability to monitor operations, control costs, maintain effective quality
controls and significantly expand our internal management, technical and
accounting systems, all of which will result in higher operating expenses. A
failure to expand these areas or to implement and improve our systems,
procedures and controls in an efficient manner and at a pace consistent with
the growth of our business could have a material adverse effect on our
business, prospects, operating results and ability to service our indebtedness,
including the notes.
 
      In addition, we will incur considerable expenses to integrate systems we
acquire with existing operations before we earn any anticipated revenue from
these new systems, which may cause our operating results to fluctuate
substantially. We will, among other things, have to integrate switching,
transmission, technical, sales, marketing, billing, accounting, quality
control, management, personnel, payroll, regulatory compliance and other
systems and operating hardware and software, some of which may be incompatible
with our existing systems. In addition, telecommunications providers generally
experience higher customer and employee turnover rates during and after an
acquisition. We cannot assure you that we will be able to successfully
integrate the systems we own or may acquire or any other businesses we may
acquire or that any acquired business will not experience high employee or
customer turnover rates after an acquisition.
 
                                       22
<PAGE>
 
      We may fail or be unable to discover certain liabilities, including
liabilities arising from non-compliance with certain federal, state or local
environmental laws by prior owners, when we perform due diligence
investigations on each company or business we seek to acquire. We may be
responsible for these liabilities as a successor owner. We generally seek to
minimize our exposure to such liabilities by obtaining indemnification from
each seller of the acquired companies and, in some cases, by deferring payment
of a portion of the purchase price to support these indemnification
obligations. However, we cannot assure you that we could enforce or collect
such indemnifications, even if obtainable, or that the indemnifications would
be sufficient in amount, scope or duration to fully offset the possible
liabilities arising from the acquisitions.
 
      We expect to finance acquisitions with cash on hand, through issuances of
debt or equity securities and through borrowings under credit arrangements,
including pursuant to the credit facility. We cannot assure you that we will be
able to obtain additional financing in order to finance our acquisition
strategy. The ability to obtain debt or equity financing is subject to market
conditions and our current debt instruments limit our ability to incur
additional indebtedness.
 
Rapid Technological Changes--Rapid and significant technological changes in the
telecommunications industry may adversely affect us.
 
      Telecommunications providers face rapid and significant changes in
technology. New technologies may be protected by patents or other intellectual
property laws and therefore may not be available. In particular, the wireless
telecommunications industry is experiencing significant technological change,
including:
 
     .  the increasing pace of digital upgrades in existing analog wireless
        systems,
 
     .  evolving industry standards,
 
     .  the allocation of new radio frequency spectrum in which to license
        and operate wireless services,
 
     .  ongoing improvements in the capacity and quality of digital
        technology,
 
     .  shorter development cycles for new products and enhancements, and
 
     .  changes in end-user requirements and preferences.
 
      Like others in the industry, we are uncertain about the extent of
customer demand as well as the extent to which airtime and monthly access rates
may continue to decline. We cannot predict the effect of technological changes
on our business, and it is possible that technological developments will have a
material adverse effect on us.
 
Extensive Regulation of our Industry--Extensive governmental regulation of the
telecommunications industry requires us to obtain regulatory approvals and
creates the possibility for adverse regulatory change.
 
Wireless
 
      The FCC regulates the licensing, construction, operation, acquisition and
sale of commercial wireless communications systems, as well as the number of
wireless licensees permitted in each market. Certain aspects of cellular
operations may also be subject to public utility regulation in the state in
which the service is provided. Changes in the regulation of commercial wireless
services (such as cellular, personal communication services, or paging),
wireless carriers, the licensing of additional connecting carriers in our
service areas, the deregulation of interconnection arrangements or the loss of
any license or licensed area previously awarded to us could have a material
adverse effect on our operations. See "Business--Regulation."
 
      The FCC continues to license additional spectrum for wireless
communications. In addition, all cellular and personal communication services
licenses in the United States are subject to renewal upon the
 
                                       23
<PAGE>
 
expiration of their initial ten-year term. Our company's initial cellular
licenses have expired and will continue to expire in the near future. To date,
however, we have successfully renewed each of our cellular licenses. We will
continue to apply for renewal of our licenses in a timely fashion. Although we
cannot assure you that these licenses will be renewed, we believe that each
license will be renewed based upon FCC rules establishing a presumption in
favor of licensees that have complied with their regulatory obligations during
the prior license term. Any failure to renew our licenses would have a material
adverse effect on our business, financial condition and results of operations.
 
      We must obtain a number of other approvals, licenses and permits in the
operation of our business, including determinations of no hazard to navigation
from the Federal Aviation Administration in connection with the construction of
cellular and personal communication services towers. Additionally, the wireless
communications industry is subject to certain state and local government
regulation. Operating costs are also affected by other governmental actions
that are beyond our control. We cannot assure you that the various federal,
state and local agencies responsible for granting licenses, approvals and
permits will do so or that, once granted, will not revoke or fail to renew
them. The absence of such licenses, approvals and permits would adversely
affect our existing operations and could delay commencement of or prohibit
business operations that we propose.
 
      In addition, the Communications Act of 1934, as amended, generally
prohibits foreign persons or entities from controlling FCC licenses or holding
interests of more than 25% in an FCC licensee. An FCC licensee may, however,
request that the FCC allow a foreign entity to hold more than a 25% interest.
These restrictions could adversely affect our ability to attract additional
equity financing.
 
      The wireless communications industry is subject to continually evolving
regulation. As new regulations are made, we may be required to modify our
business plans or operations in order to comply with any new regulations. There
can be no assurance that we can do so in a cost-effective manner, if at all.
 
      In Puerto Rico, we are also subject to regulation by the Puerto Rico
Planning Board, the Administration of Regulation and Permits and the Puerto
Rico Telecommunications Regulatory Board. The powers of these authorities
include a number of matters, such as cost-based rate-making that could have a
material adverse effect on our business, financial condition and results of
operations.
 
Wireline
 
      Lambda CLEC, our wholly-owned subsidiary, is subject to the Puerto Rico
Telecommunications Act of 1996, which grants jurisdiction over
telecommunications services and providers to the Puerto Rico Telecommunications
Regulatory Board and purports to open the Puerto Rico telecommunications market
to competition.
 
      In addition, Lambda CLEC is subject to the Communications Act. Pursuant
to the Communications Act, the FCC requires all telecommunications carriers,
including Lambda CLEC, to contribute to the federal universal service fund. The
Communications Act also requires state public utilities commissions and/or the
FCC to implement policies that mandate reciprocal compensation between local
exchange carriers. On August 1, 1996, the FCC adopted rules implementing these
policies, but various aspects of the order have been overturned by a federal
court and the decision remains subject to further judicial review.
 
General
 
      From time to time, federal, state or commonwealth legislators propose
legislation that potentially could materially affect us either beneficially or
adversely. We cannot assure you that federal, state or commonwealth governments
will not enact legislation or that the FCC, state or commonwealth regulatory
authorities will not promulgate regulation or take other actions that might
have a material adverse affect on our business. If the
 
                                       24
<PAGE>
 
FCC allocates radio spectrum for services that compete with our business, these
changes could materially and adversely affect our business, prospects,
operating results or ability to service our indebtedness, including the notes.
 
Fluctuations in Market Value of Our Licenses--The value of our cellular
licenses may decrease due to market conditions and the success of our business.
 
      A substantial portion of our assets consists of our interests in cellular
licenses held by subsidiaries. While there currently exists a market for the
purchase and sale of cellular licenses, including those in our markets, that
market may not exist in the future or the values of our licenses in that market
may fall. The future value of our interests in our cellular licenses will
depend significantly upon the success of our business. The transfer of
interests in such licenses is subject to prior FCC approval, which may have the
effect of reducing the value of the license. As a consequence, if the market
value of our cellular licenses decreases significantly, we may realize a
material loss upon the sale of any of our licenses.
 
Importance of Certain Markets--Our business will be hurt if business and
economic conditions generally worsen in our principal markets.
 
      Our success depends upon various factors related to business and economic
conditions and consumer spending in the regions where our principal operations
are located. If existing economic conditions were to deteriorate in any of our
regions, the market for cellular services to business and consumer subscribers
may grow more slowly or may decline, thereby materially and adversely affecting
our business and results of operations. The fact that we have clustered our
operations geographically may increase this risk.
 
Risks Associated with Conditions in Puerto Rico--Business and economic factors,
severe weather and political conditions in Puerto Rico may significantly affect
our operations in Puerto Rico and hurt our overall performance.
 
      Our business in Puerto Rico is dependent on the business and economic
conditions and consumer spending generally in Puerto Rico. If existing economic
conditions in Puerto Rico were to deteriorate, the market for wireless or
wireline services in Puerto Rico may grow more slowly or decline. This would
have an adverse impact on our business in Puerto Rico and, because our Puerto
Rico operations currently generate approximately 30% of our company's EBITDA,
on our financial condition and results of operations generally.
 
      In particular, our business in Puerto Rico may be materially adversely
affected by events such as hurricanes, labor strikes and the like which affect
Puerto Rico generally. Puerto Rico was hit by Hurricane Georges in September
1998. The island suffered significant damage as a result of the storm. Less
than 10% of our personal communication services towers and microwave
transmitters were damaged during the hurricane, which interrupted service to
approximately 25% of our customers in Puerto Rico. After consideration of
expected insurance recoveries, we believe it will not incur significant losses
as a result of the effects of the damage caused by Hurricane Georges. During
the nine months ended February 28, 1999, we recorded approximately $1.7 million
of insurance recoveries related to subscriber refunds within revenue. Other
hurricanes or adverse weather conditions that may hit the island from time to
time may have a material adverse effect on our business in Puerto Rico.
 
      Any change in Puerto Rico's political status with the U.S., or the
ongoing debate on such status, could also affect the economy of Puerto Rico.
The ultimate effect of possible changes in Puerto Rico's governmental and
political status is uncertain and, accordingly, we cannot assure you that such
changes will not materially adversely affect our business and results of
operations.
 
 
                                       25
<PAGE>
 
Operating Costs Due to Fraud--A substantial increase in fraudulent and/or
unbilled use of our network or costs incurred to prevent such use would affect
our business operations.
 
      Like most companies in the cellular industry, we incur costs associated
with unauthorized use of our network. Fraud increases interconnection costs,
capacity costs, administrative costs, costs incurred for fraud prevention and
payments to other carriers for unbillable fraudulent roaming. We currently
employ anti-fraud measures in our rural cellular clusters and intend to
continue to develop and invest in measures to prevent cellular fraud. Even so,
we cannot assure you that we will not incur substantial costs due to fraud. In
addition, while we have not experienced significant costs in the past due to
our anti-fraud measures and the costs associated with unauthorized use of our
cellular network, we cannot assure you that these costs will not become
substantial in the future.
 
      We have not yet experienced any fraud problems in connection with our
wireless service in Puerto Rico because of its use of CDMA technology. We
cannot assure you, however, that a fraud problem will not develop or that we
will not incur substantial costs due to fraud in the future.
 
Risk Related to Strategy to Reduce Roaming Rates--Because we both receive
revenue when cellular and personal communications services customers roam in
our service area and remit payment to other wireless service providers when our
customers roam outside our service area, a general decline in roaming rates and
our strategy of aggressively pricing roaming rates may lead to lower roaming
revenues that are not fully offset by lower payments to other providers, and
thus a decrease in results of operations.
 
      We earn much of our revenue from customers of other cellular providers
who are roaming in our markets. Roaming rates per minute pursuant to reciprocal
roaming arrangements have declined over the last several years and we expect
that such declines will continue for the foreseeable future. We have
implemented a strategy of aggressively pricing roaming rates to encourage other
cellular and personal communications services providers to include portions of
our service areas within their home calling regions and to discourage wireless
providers from expanding their footprints into our service areas. While we
benefit from lower roaming rates when we remit to other cellular providers
roaming charges incurred by our subscribers in other cellular providers'
calling regions, we receive less revenue per minute of use from customers
roaming in our markets. We cannot assure you that the decline in roaming rates
will be offset by the benefits of increased roaming minutes of use by other
cellular and personal communication services providers or that such decline
will not materially adversely affect our results of operations.
 
Possible Inability to Purchase Notes upon a Change of Control--We may not be
able to fulfill our obligations under our credit facility or the notes
following a change of control.
 
      Upon certain change of control events, each holder of notes may require
us to repurchase all or a portion of its notes at a purchase price equal to
101% of the principal amount thereof, plus accrued interest. Our ability to
repurchase the notes upon a change of control event will be limited by the
terms of our debt agreements. Upon a change of control event, we may be
required immediately to repay the outstanding principal, any accrued interest
on and any other amounts owed by us under our credit facility or the
subordinated notes financing provided by WCAS Capital Partners III, L.P. There
can be no assurance that we would be able to repay amounts outstanding under
our credit facility or obtain necessary consents under such facility to
repurchase these notes. Any requirement to offer to purchase any outstanding
notes may result in us having to refinance our outstanding indebtedness, which
we may not be able to do. In addition, even if we were able to refinance such
indebtedness, such financing may be on terms unfavorable to us. The term
"change of control" is defined in the section "Description of the New Notes--
Certain Definitions."
 
 
                                       26
<PAGE>
 
Pledge of Stock by Centennial Cellular Operating--Because we have pledged the
capital stock of many of our subsidiaries to the lenders under the credit
facility, we may encounter difficulties obtaining future financing on favorable
terms.
 
      Centennial Cellular Operating has pledged as security the shares of all
its direct and indirect subsidiaries (other than foreign subsidiaries) to the
lenders under its credit facility. The pledge of such shares could impair our
ability to obtain future financing on favorable terms, if at all. Further, in
the event Centennial Cellular Operating were to default on its obligations
under the credit facility and the lenders were to foreclose upon such pledged
capital stock, Centennial Cellular Operating, as the holding company for such
subsidiary, would likely be unable to service or repay its indebtedness,
including the notes. See "Description of Certain Indebtedness."
 
Risks Related to Co-Obligor; Guarantee by Centennial Under Credit Facility--
Centennial is not restricted by the indenture governing the outstanding notes;
in addition, we conduct our operations through a holding company structure,
which leaves the parent entity unlikely to be able to service its debt
obligations if our subsidiary defaults on its obligations.
 
      Centennial, which is a co-obligor of the notes, has no assets other than
the stock of Centennial Cellular Operating. Therefore, Centennial would be
unlikely to be able to make payments on the notes if Centennial Cellular
Operating fails to make such payments. In addition, Centennial is not be
subject to the covenants of the indenture governing the notes.
 
      Centennial has unconditionally guaranteed all obligations of its
subsidiary, Centennial Cellular Operating, which is the borrower under the
credit facility. In the event that Centennial Cellular Operating were to
default on its obligations under the credit facility and the lenders were to
seek to enforce such guarantee, Centennial would likely be unable to service or
repay its indebtedness, including the notes. See "Description of Certain
Indebtedness."
 
Changes in Tax Law--Our operations in Puerto Rico, which depends in part on
business customers using our networks, may be adversely affected if changes in
tax incentives and tax benefits available to businesses in Puerto Rico cause
companies to reduce their business activities in Puerto Rico.
 
      Section 936 of the Internal Revenue Code of 1986 was amended in 1996.
This section had historically provided tax incentives for U.S. companies to
operate in Puerto Rico and to reinvest the earnings from their Puerto Rico
operations in Puerto Rico. One result of this tax preference was to encourage
the development of business and manufacturing operations in Puerto Rico and to
make available to certain Puerto Rico businesses financing at rates below those
generally offered by commercial banks. As a result of the 1996 amendment to
Section 936, such favorable financing rates are no longer available.
 
      The tax benefits available to corporations, such as pharmaceutical
companies, doing business in Puerto Rico phase out in annual increments through
2005. Consequently, such corporations may reduce or close their Puerto Rico
operations and may reduce their re-investments in Puerto Rico. The changes may
also reduce the incentives for new investments in Puerto Rico. We do not yet
know the full extent to which our business in Puerto Rico will be affected by
such changes in the tax law. However, if the change diminishes the overall
level of business activity in Puerto Rico, it could cause our business
customers and other cellular subscribers roaming within our coverage area to
reduce their use of telecommunications. A significant reduction in such use
would have a material adverse effect on our business and results of operations.
 
                                       27
<PAGE>
 
Bankruptcy Risks Related to Escrow and Pledge Account--If we entered
bankruptcy, you would not be able to foreclose on the escrow funds securing the
interest payments without approval from a bankruptcy court.
 
      If we or any of our subsidiaries commence a bankruptcy or reorganization
case, or one is commenced against us, the bankruptcy law may prevent the
trustee under the indenture governing the notes from foreclosing on and selling
the escrow funds if an event of default on the notes occurs. Under applicable
bankruptcy law, secured creditors such as the holders of the notes are
prohibited from foreclosing upon or disposing of a debtor's property without
prior bankruptcy court approval. See "Description of the New Notes--Security."
 
Fraudulent Conveyance--A court may conclude that we issued the outstanding
notes for inadequate consideration and at a time when we were insolvent or that
we issued the notes with intent to defraud our creditors.
 
      We believe that we incurred the indebtedness represented by the notes for
proper purposes and in good faith. Based on current asset valuations and other
financial information, we also believe that we were solvent after issuing the
notes, consummating the merger and completing the other financings required for
the merger. We expect that we will have sufficient capital to carry on our
business and to pay our debts as they mature. See "--Significant Indebtedness
and Interest Payment Obligations." Notwithstanding this belief, however, if an
unpaid creditor or a representative of a creditor (such as a trustee in
bankruptcy or a debtor-in-possession) were to sue us in an appropriate court,
the court might find that, when we issued the notes,
 
    (1) we incurred the indebtedness with intent to hinder, delay or defraud
        any present or future creditor or we contemplated insolvency with a
        design to prefer one or more creditors to the exclusion in whole or
        in part of others; or
 
    (2) we incurred the indebtedness for less than reasonably equivalent
        value and, at the time, we
 
     .  were insolvent,
 
     .  were rendered insolvent by reason of such incurrence,
 
     .  were engaged in a business or transaction for which our remaining
        assets constituted unreasonably small capital,
 
     .  intended to incur, or believed that we would incur, debts beyond
        our ability to pay such debts as they matured or
 
     .  were a defendant in an action for money damages or had a judgment
        for money damages docketed against us (in either case, if after
        final judgment, the judgment remained unsatisfied).
 
      In such event, the court could, among other things, (x) void all or a
portion of our obligations to you, the effect of which would be that you may
not be repaid in full and/or (y) subordinate our obligations to you to our
other existing and future indebtedness to a greater extent than would otherwise
be the case, the effect of which would entitle other creditors to be paid in
full before any payment could be made on the notes. We cannot assure you that,
after providing for all prior claims, there would be sufficient assets to
satisfy the claims of holders of the notes.
 
      Courts applying the laws of different jurisdictions will use different
standards to determine whether we are insolvent for purposes of the foregoing.
Generally, however, a company would be considered insolvent if the sum of the
company's debts is greater than all of the company's property at a fair
valuation, or if the present fair saleable value of the company's assets is
less than the amount that will be required to pay its probable liability on its
existing debts as they become absolute and mature. We cannot predict what
standards a court would apply to determine whether we were solvent at the
relevant time.

Potential Failure of Computer Systems to Recognize Year 2000--The potential
failure of our computer systems and those of third parties with whom we deal to
recognize the year 2000 could significantly disrupt our operations, causing a
decline in cash flow and revenue and other difficulties.
 
      During fiscal 1998, we began a review of our computer systems and related
software to identify systems and software that might malfunction due to a
misidentification of the Year 2000. Most of our customer-related computer
systems and databases, including our billing systems, are managed by third
parties under contractual arrangements. We have requested those third parties
to advise us as to whether they anticipate difficulties in addressing Year 2000
problems and, if so, the nature of such difficulties. Our management has not
finally determined the cost associated with its Year 2000 readiness efforts and
the related potential impact on our results of operations. Amounts expended to
date have not been material. We cannot assure you that the systems of other
companies on which we rely, including third party billers, will be converted in
time or that any such failure to convert by another company will not have a
material adverse effect on our business, financial condition or results of
operations.
 
Risks Associated With Certain Changes in Senior Management--We have new senior
managers who have not operated our company in the past and other key
individuals may not stay with us when their contracts expire.
 
      Michael J. Small, who is the President and Chief Executive Officer of
Centennial, became the Chief Executive Officer of Centennial upon the
consummation of the merger with CCW Acquisition Corp. Mr. Small has 17 years of
experience in the telecommunications industry but had no experience managing
our operations. We have employment contracts with seventeen members of senior
management, including Mr. Small, whose contract expires on September 30, 2002;
Rudy J. Graf, who is the President and Chief Executive Officer of Centennial de
Puerto Rico and Peter Chehayl, who became Senior Vice President and Chief
Financial Officer following the Merger. To the extent that these key
individuals do not remain with Centennial at the end of their respective
employment terms, such change in management could have a material adverse
effect on our company unless we can obtain a suitable replacement in a timely
manner. Our management will also be required to devote additional time and
resources toward recruitment, hiring and training to fill such positions,
which, if substantial, could result in a material adverse effect on our
business, prospects, operations or results of operations. If the senior
management team is not put into place, or if our executive officers do not
achieve their management objectives in a timely manner, our business,
prospects, operating results and ability to service our indebtedness, including
the notes, may be materially adversely affected.
 
Control by the Equity Investors--A group of affiliated stockholders controls
the voting power of Centennial.
 
      Following the Merger, 92.9% of Centennial's outstanding shares of common
stock are held by Welsh Carson VIII, certain of its affiliates and certain
other equity investors. Accordingly, these equity investors will, directly or
indirectly, control our company and have the power to elect all of our
directors, appoint new management and approve or reject any action requiring
the approval of stockholders, including adopting amendments to our charter and
approving mergers and sales of all or substantially all of our assets. In
addition, the existence of a controlling stockholder may have the effect of
making it difficult for a third party to acquire, or of discouraging a third
party from seeking to acquire, a majority of the outstanding Centennial common
stock. See "Principal Stockholders" and "Certain Relationships and Related
Transactions--Equity Investor Agreements."

Investment Interests; Capital Calls--If we do not continue to fund certain
investment partnerships in which we hold interests, our ownership in these
partnerships may be diluted.
 
      We have a limited ability to direct the operation of any system in which
we now or in the future hold a minority investment as a limited partner. In
addition, these investment partnerships are entitled to make certain demands
for capital contributions, including to complete acquisitions by the limited
partnerships. If we do not meet such a capital call, our ownership interest in
such system may be diluted. Capital calls with respect to such investment
interests for the fiscal years ended May 31, 1998, 1997 and 1996 were
approximately $0.8 million, $2.9 million and $1.5 million, respectively. We
have, to date, paid all capital calls that we have received. Although we
anticipate that such capital calls will decrease over time, we cannot assure
you that such capital calls will, in fact, decrease. We cannot assure you that
we will be able to pay such capital calls when due. In addition, under the
indenture relating to the notes, Centennial Cellular Operating will be
permitted to dividend to Centennial all cash received from Centennial Cellular
Operating's non-subsidiary investment interests.
 
Equipment Failure; Natural Disaster
 
      A major equipment failure or a natural disaster affecting any one of our
central switching offices or certain of our cell sites or microwave links could
have a material adverse effect on our business, prospects, operating results or
ability to service our indebtedness, including the notes. In particular, our
business in Puerto Rico may be materially adversely affected by events such as
hurricanes, labor strikes and the like which affect Puerto Rico generally.
Puerto Rico was hit by Hurricane Georges in September 1998 and the island
suffered significant damage as a result of the storm. After giving effect to
insurance proceeds that we expect to receive, there will be no material adverse
impact on our operating results. Other hurricanes or adverse weather conditions
that may hit the island from time to time may have a material adverse effect on
our business in Puerto Rico. Although we currently carry "business
interruption" insurance, our insurance policies may not entirely cover all
damages we may suffer.
 
Radio Frequency Emission Concerns
 
      Media reports have suggested that certain radio frequency emissions from
portable cellular telephones may be linked to cancer and interfere with heart
pacemakers and other medical devices. Concerns over radio frequency emissions
and interference may have the effect of discouraging the use of cellular
telephones, which could have an adverse effect upon our business. During the
past two years, the FCC has updated its guidelines and methods for evaluating
the environmental effects of radio frequency emissions. The updated guidelines
generally are more stringent than the previous rules, based on recommendations
of federal health and safety agencies, including the Environmental Protection
Agency and the Food and Drug Administration. However, we do not believe these
guidelines will have a material impact on our operations. Among the guidelines
are limits for specific absorption rate for evaluation of certain hand-held
devices such as cellular telephones, as well as guidelines for the evaluation
of cellular transmitting facilities. We believe that the cellular telephones
currently marketed and generally used, as well as our transmission facilities,
comply with the new standards. Moreover, the FCC preempted state and local
government regulation of cellular and other personal wireless services
facilities based on radio frequency environmental effects to the extent that
such facilities comply with the FCC's rules concerning such radio frequency
emissions. Potential interference to medical devices involves primarily digital
transmissions rather than analog. Industry, government and medical experts have
been conducting tests and developing methods for reducing or eliminating such
interference.

Absence of Public Market for the New Notes--If an active trading market does
not develop, you may have difficulties reselling the notes.
 
      The notes are being offered to the holders of the outstanding notes. The
outstanding notes were sold to the initial purchasers on December 14, 1998 and
then resold to "qualified institutional buyers" (as defined in Rule 144A under
the Securities Act) and pursuant to offers and sales outside the United States
within the meaning of Regulation S under the Securities Act and are eligible
for trading in the Private Offerings, Resale and Trading through Automated
Linkages (PORTAL) market. The new notes are securities for which there
currently is no market. If the new notes are traded, they may trade at a
discount from their face value, depending upon prevailing interest rates, the
market for similar securities and other factors. We do not intend to apply for
listing of the notes on any securities exchange or the Nasdaq National Market.
Accordingly, we cannot assure you that a liquid trading market for the notes
will develop.
 
      Historically, there has been substantial volatility in the market for
non-investment grade debt, such as the notes, due to market disruptions. This
volatility has increased in recent months and the liquidity of non-investment
grade securities has declined significantly. We cannot assure you that the
market, if any, for the notes will not be subject to similar disruptions. Any
such disruptions may have a material adverse effect on the holders of the
notes.
 
Consequences of the Exchange Offer to Non-Tendering Holders of the Outstanding
Notes--If you do not exchange your notes for new notes, your outstanding notes
may trade at discount because you may not be able to transfer such notes.
 
      In the event the exchange offer is consummated, we will not be required
to register the old notes under the Securities Act. In such event, the notes
would rank pari passu with the outstanding notes, and the holders of
outstanding notes seeking liquidity in their investment would have to rely on
exemptions from registration requirements under the securities laws, including
the Securities Act. A reduction of the aggregate principal amount of the
currently outstanding notes as a result of the consummation of the exchange
offer may have an adverse effect on the ability of holders of the outstanding
notes to transfer such notes.

                                   THE MERGER
 
      The following is a summary of the structure of the merger that was
consummated on January 7, 1999. This summary does not purport to be complete
and is qualified in its entirety by reference to the merger agreement, a copy
of which has been filed with the SEC.
 
Structure of the Merger
 
      Pursuant to the merger agreement and subject to the terms and conditions
set forth in the merger agreement, CCW Acquisition Corp. merged with and into
Centennial and Centennial was the surviving corporation in the merger. At the
effective time of the merger, by virtue of the merger,
 
     .  each issued and outstanding share of Class A Common Stock, par value
        $.01 per share, of Centennial was converted into the right to
        receive, subject to proration so that the total number of common
        shares of the surviving corporation received by the holders of
        Centennial common shares immediately before the merger was equal to
        7.1% of the common shares of the surviving corporation outstanding
        immediately after the effective time of the merger, either (a) one
        common share of the surviving corporation or (b) $41.50 in cash;
 
     .  all outstanding shares of Class B Common Stock, par value $.01 per
        share, were converted into the right to receive; $41.50 in cash; and
 
     .  all outstanding shares of Convertible Preferred Stock and Second
        Series Convertible Preferred Stock of Centennial were converted into
        the right to receive $41.50 in cash as if such shares had been
        converted into shares of Centennial.
 
      The surviving corporation in the merger continues to operate under the
name "Centennial Cellular Corp."
 
Financing of the Merger
 
      A total of approximately $1.87 billion was required to pay the cash
consideration to Centennial stockholders in the merger, repay our indebtedness
(including the purchase of tendered notes in debt tender offers), pay the
related fees and expenses and purchase pledged securities. See "Summary--The
Merger--Sources and Uses of Funds." The sources of funding for the merger and
the related transactions were the credit facility, the financing from WCAS
Capital Partners III, L.P., the common equity contribution and the offering of
the old notes (collectively, the "Merger Financing").
 
      In connection with the merger, Centennial Cellular Operating and its
Puerto Rico subsidiary borrowed approximately $936.0 million under the $1,050
million credit facility. A group of lenders provided Centennial Cellular
Operating with the credit facility, consisting of an $900 million term loan
facility and a $150 million revolving credit facility. See "Description of
Certain Indebtedness."
 
      WCAS Capital Partners III, L.P., an investment partnership affiliated
with Welsh Carson VIII, purchased, at the time of the consummation of the
merger, unsecured subordinated notes due 2009 of Centennial and common shares
of Centennial at an aggregate price of $180 million. In addition, the other
equity investors made a common equity contribution of $400 million to purchase
common shares at the time of the consummation of the merger. In total, the
equity investors owned 9,638,554 common shares immediately following the
consummation of the Merger (prior to giving effect to a three-for-one stock
split effected on January 8, 1999).

Debt Tender Offers and Solicitations
 
      In connection with the merger, Centennial consummated debt tender offers
to acquire approximately 99% of its outstanding notes due 2001 and 2005 and to
eliminate the interest expense associated with the old notes. Pursuant to
consent solicitations which were made in order to enhance our operating and
financial flexibility of, Centennial entered into supplemental indentures,
approved by the required number of holders of the tendered notes, to eliminate
most of the restrictive covenants contained in the indentures governing the
tendered notes and to amend certain other provisions contained in such
indentures. As of the expiration date of the debt tender offers, valid
irrevocable tenders and consents had been received from 99.4% of holders of
notes due 2001 and 99.8% of holders of the notes due 2005. From time to time in
the future, we may seek to acquire any notes due 2001 and 2005 that remain
outstanding following the consummation the debt tender offers, through open
market purchases, privately negotiated transactions, tender offers, exchange
offers or otherwise, upon such terms and at such prices as it may determine,
which may be more or less than the price to be paid in the related debt tender
offer and could be for cash or other consideration. In addition, we may elect
to redeem or defease any notes due 2001 or 2005 that remain outstanding in
accordance with the terms of the applicable note indenture.
 
                                       33
<PAGE>
 
                                USE OF PROCEEDS
 
      We will not receive any proceeds from the issuance of new notes pursuant
to the exchange offer. The offering of notes resulted in net proceeds to us, as
the successor to Centennial Finance Corp., and Centennial Cellular Operating of
approximately $357.1 million (after payment of underwriting discounts and other
issuance costs totaling approximately $12.9 million). The net proceeds from the
offering, the mezzanine financing and the common equity contribution, together
with borrowings under the credit facility, were used to (i) fund payment of the
cash consideration in the merger, (ii) repay or repurchase certain indebtedness
of Centennial (including the purchase of notes tendered in the debt tender
offers), (iii) pay the fees and expenses incurred in connection with the
merger, the Merger Financings and the other transactions contemplated by the
merger agreement, and (iv) purchase the pledged securities.
 
      The following table sets forth the sources and uses of funds in
connection with the financing of the merger as of the merger's consummation on
January 7, 1999:

    amount of $900 million and a revolving credit facility in an aggregate
    principal amount of up to $150 million. The borrowers under these
    facilities are Centennial Cellular Operating and, for a portion thereof,
    Centennial de Puerto Rico. Centennial, together with the direct and
    indirect subsidiaries of Centennial Cellular Operating (excluding initially
    Centennial de Puerto Rico and its subsidiaries, which subsidiaries have

    facility), have unconditionally guaranteed, jointly and severally, the
    obligations of the borrowers under such facilities. See "Description of
    Certain Indebtedness."
 
(2) Upon consummation of the merger, approximately $57.5 million of the
    proceeds from the old notes was deposited with the trustee to purchase
    pledged securities to pay the first three scheduled interest payments on
    the notes at the stated interest rate. See "Description of the New Notes--
    Security."

                               THE EXCHANGE OFFER
 
Terms of the Exchange Offer
 
      The holders of the notes currently are entitled to certain registration
rights under a registration rights agreement. Pursuant to the registration
rights agreement, we became obligated to file with the SEC a registration
statement covering the offer by us to the holders of the notes to exchange all
of the notes for the new notes. This exchange offer, if consummated, will
satisfy our obligations under the registration rights agreement.
 
      Upon the terms and subject to the conditions set forth in this prospectus
and in the accompanying letter of transmittal, we will accept all properly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the
expiration date. We will issue $1,000 principal amount of new notes in exchange
for each $1,000 principal amount of outstanding notes accepted in the exchange
offer. Holders may tender some or all of their notes pursuant to the exchange
offer.
 
      Based on an interpretation by the staff of the SEC set forth in no-action
letters issued to third parties, we believe that the new notes issued pursuant
to the exchange offer in exchange for notes may be offered for resale, resold
and otherwise transferred by the holders thereof (other than any such holder
that is our "affiliate" within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such new notes are acquired in
the ordinary course of such holders' business, and such holders have no
arrangement with any person to participate in the distribution of such new
notes. See Morgan Stanley & Co., Inc., SEC No-Action Letter (available June 5,
1991), Exxon Capital Holdings Corporation, SEC No-Action Letter (available May
13, 1988), and Shearman & Sterling, SEC No-Action Letter (available July 2,
1993).
 
      If you were to be participating in the exchange offer for the purposes of
distributing securities in a manner not permitted by the SEC's interpretation,
you (i) could not rely on the position of the staff of the SEC enunciated in
Exxon Capital Holdings Corporation or similar interpretive letters and (ii)
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction.
 
      Each broker-dealer that receives new notes for its own account pursuant
to the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new notes. The letter of transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This prospectus, as it may be amended or supplemented from time
to time, may be used by a broker-dealer in connection with resales of new notes
received in exchange for notes where such notes were acquired by such broker-
dealer as a result of market-making activities or other trading activities. See
"Plan of Distribution."
 
      As of the date of this prospectus, there was $370,000,000 aggregate
principal amount of the notes outstanding. This prospectus, together with the
letter of transmittal, is being sent to all such registered holders as of the
date of this prospectus.
 
      We shall be deemed to have accepted validly tendered notes when, as and
if we have given written notice of acceptance to the exchange agent. The
Exchange Agent will act as agent for the tendering holders of notes for the
purposes of receiving the new notes from us and delivering new notes to the
tendering holders.
 
      If any tendered notes are not accepted for exchange because of an invalid
tender, certificates for any such unaccepted notes will be returned, without
expense, to the tendering holder thereof as promptly as practicable after the
expiration date.
 
 
                                       36
<PAGE>
 
      If notes are not tendered, they will remain outstanding and will continue
to accrue interest from their date of issue, December 14, 1998, at a rate of 10
3/4% per annum.
 
      In the event the exchange offer is consummated, we will not be required
to register the notes that are not tendered. In such event, holders of notes
seeking liquidity in their investment would have to rely on exemptions to
registration requirements under the securities laws, including the Securities
Act. See "Risk Factors--Consequences of the Exchange Offer to Non-Tendering
Holders of the notes."
 
      The term "expiration date" means the expiration date set forth on the
cover page of this prospectus, unless we, in our discretion, extend the
exchange offer, in which case the term "expiration date" means the latest date
to which the exchange offer is extended.
 
      In order to extend the expiration date, we will notify the exchange agent
of any extension by written notice and will mail to the record holders of notes
an announcement thereof, each prior to 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date. Such
announcement may state that we are extending the exchange offer for a specified
period of time.
 
      In addition, we will issue notice of each such extension by press release
or other public announcement as contemplated by the provisions of Rule 14e-1
promulgated under the exchange act.
 
Interest on the New Notes
 
      The notes will bear interest from December 14, 1998, payable semiannually
on June 15 and December 15 of each year, commencing June 15, 1999, at a rate of
10 3/4% per annum.
 
Procedures for Tendering
 
      The tender to us of notes by you pursuant to one of the procedures set
forth below will constitute an agreement between you and us in accordance with
the terms and subject to the conditions set forth in this prospectus and in the
letter of transmittal.
 
      You may tender your notes by
 
     .  properly completing and signing the letter of transmittal or a
        facsimile of the letter of transmittal (all references in this
        prospectus to the letter of transmittal will be deemed to include a
        facsimile) and delivering the letter of transmittal, together with
        the certificate or certificates representing the notes being
        tendered and any required signature guarantees, to the exchange
        agent at its address set forth on the back cover of this prospectus
        on or prior to the expiration date (or complying with the procedure
        for book-entry transfer described below), or
 
     .  complying with the guaranteed delivery procedures described below.
 
      If your tendered notes are registered in the name of the signer of the
letter of transmittal and the notes to be issued in exchange for your notes are
to be issued (and any untendered notes are to be reissued) in the name of the
registered holder (which term, for the purposes described in this prospectus,
shall include any participant in The Depository Trust Company (also referred to
as a book-entry transfer facility) whose name appears on a security listing as
the owner of notes), the signature of such signer need not be guaranteed. In
any other case, your tendered notes must be endorsed or accompanied by written
instruments of transfer in form satisfactory to us and duly executed by the
registered holder, and the signature on the endorsement or instrument of
transfer must be guaranteed by a commercial bank or trust company located or
having an office or correspondent in the United States, or by a member firm of
a national securities exchange or of the National Association of Securities
Dealers, Inc., which firm must also be a member of or participant in the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Program or the Stock
 
                                       37
<PAGE>
 
Exchanges Medallion Program (any of these banks, trust company or member firms
are referred to as an "eligible institution"). If the notes and/or notes not
exchanged are to be delivered to an address other than that of the registered
holder appearing on the note register for the notes, the signature in the
letter of transmittal must be guaranteed by an eligible institution.
 
      The method of delivery of notes and all other documents is at your
election and risk. If you send your certificates, letters of transmittal and
related documents by mail, it is recommended that you use registered mail,
return receipt requested, and the mailing be made sufficiently far in advance
of the expiration date to permit delivery to the exchange agent on or before
the expiration date.
 
      The exchange agent will make a request promptly after the date of this
prospectus to establish accounts with respect to the notes at the book-entry
transfer facility for the purpose of aiding the exchange offer, and subject to
the establishment of these accounts, any financial institution, that is a
participant in the book-entry transfer facility's system may make book-entry
delivery of notes by causing such book-entry transfer facility to transfer
notes into the exchange agent's account with respect to the notes in accordance
with the book-entry transfer facility's procedures for such transfer. Although
delivery of notes may be effected through book-entry transfer into the exchange
agent's accounts at the book-entry transfer facility, an appropriate letter of
transmittal with any required signature guarantee and all other required
documents must in each case be transmitted to and received or confirmed by the
exchange agent at its address set forth on the back cover page of this
prospectus on or prior to the expiration date, or, if the guaranteed delivery
procedures described below are complied with, within the time period provided
under such procedures.
 
      If you desire to accept the exchange offer, and

a letter, telegram or facsimile transmission from an eligible institution
setting forth your name and address, the names in which the notes are

tendered, and stating that the tender is being made thereby and guaranteeing
that within five New York Stock Exchange trading days after the date of
execution of such letter, telegram or facsimile transmission by the eligible
institution, the notes, in proper form for transfer (or a confirmation of book-
entry transfer of such notes into the Exchange Agent's account at the book-
entry transfer facility), will be delivered by such eligible institution
together with a properly completed and duly executed letter of transmittal (and
any other required documents). Unless notes being tendered by the above-
described method are deposited with the exchange agent within the time period
set forth above (accompanied or preceded by a properly completed letter of
transmittal and any other required documents), we may, at our option, reject
the tender. Copies of a notice of guaranteed delivery which may be used by
eligible institutions for the purposes described in this paragraph are

        notice of guaranteed delivery or letter, telegram or facsimile
        transmission to similar effect (as provided above) from an eligible
        institution is received by the exchange agent. Issuances of new
        notes in exchange for notes tendered pursuant to a notice of
        guaranteed delivery or letter, telegram or facsimile transmission to
        similar effect (as provided above) by an eligible institution will
        be made only against deposit of the Letter of Transmittal (and any
        other required documents) and the tendered notes.

      All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of notes will be determined
by us, which determination will be final and binding. We reserve the absolute
right to reject any or all tenders not in proper form or the acceptance for
exchange of which may, in the opinion of our counsel, be unlawful. We also
reserve the absolute right to waive any of the conditions of the exchange offer
or any defect or irregularity in the tender of any notes. None of us, the
exchange agent or any other person will be under any duty to give notification
of any defects or irregularities in tenders or incur any liability for failure
to give such notification.
 
      By tendering, you will represent to us that, among other things, (i) the
notes acquired pursuant to the exchange offer are being obtained in the
ordinary course of your business, (ii) you have no arrangement with any person
to participate in the distribution of such new notes, (iii) you are not an
"affiliate," as defined under Rule 405 of the Securities Act, of us, and (iv)
if you are a broker or a dealer (as defined in the Exchange Act), that you
acquired the notes for your own account as a result of market-making activities
on other trading activities and that you have not entered into any arrangement
or understanding with us or any of our "affiliates" to distribute the new notes
received in the exchange offer.
 
Withdrawal of Tenders
 
      Except as otherwise provided herein, tenders of notes may be withdrawn at
any time prior to 5:00 p.m., New York City time, on the expiration date.
 
      To withdraw a tender of notes in the exchange offer, a written
transmission notice of withdrawal via telegram, telex, facsimile transmission
or letter must be received by the exchange agent at its address set forth
herein prior to 5:00 p.m., New York City time, on the expiration date. 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 certificate number or numbers and principal amount of
such notes), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such notes were
tendered (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 depositor 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 withdrawal
notices will be determined by us, which determination shall be final and
binding on all parties. Any notes you withdrew will be deemed not to have been
validly tendered for purposes of the exchange offer, and no new notes will be
issued to you with respect thereto unless the notes so withdrawn are validly
retendered. Any notes that have been tendered but that are not accepted for
exchange will be returned to them as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. Properly withdrawn
notes may be retendered by following one of the procedures described above
under "Procedures for Tendering" at any time prior to the expiration date.

(1) Represents our proportionate share of profits and losses based on our
    interest in earnings of limited partnerships controlled and managed by
    other cellular operators which we account for on the equity method.
(2) Represents the percentage share of earnings of our consolidated
    subsidiaries that is allocable to unaffiliated holders of minority
    interests.
(3) EBITDA is defined, for any period, as earnings before income from minority
    cellular investment interests that are controlled and managed by third
    parties, allocations to minority interests in consolidated subsidiaries,
    interest expense, interest income, income taxes, depreciation and
    amortization, recapitalization costs, extraordinary loss on early
    extinguishment of debt and gain on sale of assets. EBITDA is presented
    because it is a widely accepted financial indicator of a company's ability
    to service and/or incur indebtedness. EBITDA should not be considered an
    alternative to net income as a measure of our operating results or to cash
    flow as a measure of liquidity. In addition, although the EBITDA measure of
    performance is not recognized under generally accepted accounting
    principles, it is widely used by
 
                                       43
<PAGE>
 
   various companies as a general measure of a company's performance because it
   assists in comparing performance on a relatively consistent basis across
   companies without regard to depreciation and amortization, which can vary
   significantly depending on accounting methods (particularly where
   acquisitions are involved) or non-operating factors such as historical cost
   bases. Because EBITDA is not calculated identically by all companies, the
   presentation herein may not be strictly comparable to other similarly titled
   measures of other companies.
 
(4) As of period-end.
 
(5) For the years ended May 31, 1995 and May 31, 1994, the number of Net Pops
    is based on 1990 population figures of a metropolitan service area or a
    rural service area, as derived from the 1990 U.S. Census data.
 
(6) The penetration rate equals the percentage of total population in our
    service areas who are subscribers to our cellular service as of period-end.
 
(7) ARPU is defined as total monthly revenue per average subscriber.
 
(8) For the year ended as of the date shown. Determined for each period as
    total marketing cost plus cost of equipment sales (net of associated
    revenue), divided by the total subscriber activations during the fiscal
    year.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
      The following pro forma consolidated financial statements have been
derived by the application of pro forma adjustments to Centennial's historical
consolidated financial statements incorporated by reference into this
prospectus. The unaudited pro forma statements of operations and other
unaudited pro forma supplemental financial information gives effect to (i) the
Merger Financings and (ii) the debt tender offers and the repayment or
conversion of other existing indebtedness of Centennial. The pro forma
statements of operations information for the fiscal year ended May 31, 1998 and
the nine months ended February 28, 1999 have been prepared as if such
transactions had occurred at June 1, 1997. The adjustments are described in the
accompanying notes. You should not consider the pro forma consolidated
financial statements to be indicative of actual results that would have been
achieved had the merger and related transactions been consummated on the date
or for the periods indicated and do not purport to indicate results of
operations as of any future date or for any future period. You should read the
pro forma consolidated financial statements with Centennial's historical
financial statements and the notes to the historical financial statements
incorporated by reference in this prospectus.
 
      A pro forma balance sheet as of February 28, 1999 is not presented
because the merger occurred on January 7, 1999. Accordingly, the February 28,
1999 historical consolidated balance sheets include the events described above.
 
      The pro forma adjustments were applied to the respective historical
consolidated financial statements to reflect and account for the merger as a
recapitalization. Accordingly, the historical basis of the Centennial's assets
and liabilities have not been affected by the transaction.

                  NOTES TO PRO FORMA STATEMENTS OF OPERATIONS
                            (Dollars in thousands)
 
     The pro forma financial data have been derived by the application of pro
forma adjustments to Centennial's historical financial statements for the
periods noted. The merger has been accounted for as a recapitalization.
Accordingly, the historical basis of Centennial's assets and liabilities have
not been affected by the transaction. The pro forma financial data assume that
there were no dissenting stockholders to the merger.
 
     (a) The pro forma statement of operations of Centennial Cellular
Operating includes all of the same adjustments made for Centennial noted below
except interest expense related to the subordinated notes described in the
table under note (e).
 
     (b) To eliminate interest income on overnight deposits.
 
     (c) Represents estimated monitoring fee to be paid to affiliates of Welsh
Carson VIII and Blackstone.
 
     (d) The pro forma statements of operations for the year ended May 31,
1998 do not include any adjustments for one-time non-recurring expenses
incurred at the closing of the recapitalization by Centennial and Centennial
Cellular Operating. Such amounts are recorded in the Statement of Operations
for the nine months ended February 28, 1999 and are deducted as an adjustment
in determining pro forma loss for the period.
 
     (e) The pro forma adjustments to interest expense reflect the following:

      (h) EBITDA is defined, for any period, as earnings before income from
minority cellular investment interests that are controlled by third parties,
allocations to minority interests in consolidated subsidiaries, interest
expense, interest income, income taxes, depreciation and amortization,
recapitalization costs, extraordinary loss on early extinguishment of debt and
gain on sale of assets. EBITDA is presented because it is a widely accepted
financial indicator of a company's ability to service and/or incur
indebtedness. EBITDA should not be considered an alternative to net income as a
measure of Centennial's operating results or to cash flow as a measure of
liquidity. In addition, although the EBITDA measure of performance is not
recognized under generally accepted accounting principles, it is widely used by
various companies as a general measure of a company's performance because it
assists in comparing performance on a relatively consistent basis across
companies without regard to depreciation and amortization, which can vary
significantly depending on accounting methods (particularly where acquisitions
are involved) or non-operating factors such as historical
 
                                       49

cost bases. Because EBITDA is not calculated identically by all companies, the
presentation herein may not be strictly comparable to other similarly titled
measures of other companies.
 
      Pro forma EBITDA is calculated as follows:

                           Centennial Cellular Corp.
 
      Our company is one of the largest independent wireless telecommunications
service providers in the United States and Puerto Rico with approximately 10.8
million Net Pops and 426,700 subscribers as of February 28, 1999. Centennial
Rural Cellular serves 5.8 million Net Pops and its service area covers
approximately 81,645 square miles. Our subsidiary, Centennial de Puerto Rico,
is a fully integrated provider of communications services in Puerto Rico. These
operations utilize a personal communications services license that covers 3.8
million Pops in Puerto Rico and the U.S. Virgin Islands and a competitive local
exchange carrier license to operate in Puerto Rico. In addition, we own
minority shares, representing approximately 1.2 million Net Pops, in certain
other cellular operations controlled and managed by other cellular operators
(referred to as "minority cellular investment interests").
 
      The table below shows certain data for each of our two principal business
segments.

</TABLE>
 
      For the year ended May 31, 1998, our company earned revenue of $237.5
million, representing a compound annual growth rate of 45% over the previous
two fiscal years. EBITDA for the year ended May 31, 1998 was $99.2 million,
representing a compound annual growth rate of 44% over the previous two fiscal
years.
 
      The success of our company's operating and financial performance has been
driven by the quality and experience of its management and employees. We expect
to continue to benefit from the experienced members of operating management who
are expected to remain at Centennial Rural Cellular following the merger. This
management team built us through internal growth and acquisitions from
approximately 1.7 million Net Pops in 1988 to approximately 10.8 million Net
Pops (including those in Puerto Rico and minority cellular investment
interests) as of February 28, 1999. The addition of Michael Small, formerly the
Chief Financial Officer of 360(degrees) Communications Company (now a
subsidiary of ALLTEL Corporation), as our Chief Executive Officer following the
merger complements the existing management team. Rudy J. Graf, who has been the
Chief Operating Officer of Centennial since 1991, will continue to manage our
day-to-day operations.
 
Rural Cellular Systems
 
      Our domestic consolidated systems are among the leading independent
providers of rural non-wireline cellular telecommunications services. We
believe our rural and small-city cellular systems provide strong growth
opportunities due to lower penetration rates and higher subscriber growth
rates. We focus on underdeveloped rural and small-city cellular areas that have
a significant number of potential customers for wireless communications because
we believe these areas offer:
 
                                       51
<PAGE>
 
     .  Potential Penetration Growth. We believe these areas are in the
        early stages of their growth cycles and offer significant
        opportunities for increases in penetration and cellular usage;
 
     .  Insulation from Potential Competition. These regions are currently
        subject to less competition from other wireless providers (such as
        personal communications services) as compared to larger metropolitan
        service areas, and the population density of these regions suggests
        that the build-out of a personal communications services network may
        not be economically attractive to competitors at present; and
 
     .  Above-Average Revenue per Subscriber. Our domestic markets, which
        are strategically located between larger metropolitan areas, tend to
        exhibit long commute times and well-traveled roadways that have the
        potential to generate high levels of cellular minutes of use and
        roaming revenues.
 
      Our domestic cellular interests consist primarily of three operating
clusters:
 
     .  Michiana Cluster contains approximately 3.4 million Net Pops in
        Michigan, Ohio and Indiana, covering portions of three major
        interstate highways that connect Chicago, Detroit and Indianapolis.
 
     .  East Texas/Louisiana Cluster contains approximately 2.1 million Net
        Pops, covering portions of interstate highway I-10, as well as
        sections of Texas, Louisiana and Mississippi adjacent to Houston,
        New Orleans, Shreveport and Baton Rouge.
 
     .  Southwestern Cluster contains approximately 296,000 Net Pops,
        covering the Yuma, Arizona and El Centro, California markets and is
        bordered by Los Angeles to the northwest, San Diego to the west,
        Phoenix to the east and Mexicali, Mexico to the south.
 
      Our domestic operations have achieved significant increases in revenue,
EBITDA and number of subscribers since 1988. For the year ended May 31, 1998,
our domestic operations earned revenue of $182.9 million, representing a
compound annual growth rate of 28% over the previous two fiscal years. EBITDA
from domestic operations for the year ended May 31, 1998 was $86.7 million,
representing a compound annual growth rate of 34% over the previous two fiscal
years. As of May 31, 1998, our domestic operations had approximately 252,700
subscribers, representing a compound annual growth rate of 37% over the number
of subscribers in the previous two fiscal years.
 
Puerto Rico Systems
 
      Our Puerto Rico business, which is conducted through Centennial de Puerto
Rico, is a facilities-based independent cellular provider of a broad range of
wireless and wireline services in the Commonwealth of Puerto Rico (an area
covering approximately 3.8 million Pops). It is (i) the only provider of
personal communications services in the Puerto Rico market, (ii) a provider of
facilities-based wireless local loop services to both business and residential
customers, and (iii) a provider of local, long distance and enhanced data
services through its subsidiary, Lambda CLEC, which competes with the incumbent
Puerto Rico Telephone Company. We believe that Puerto Rico represents an
attractive market for communications services due to unmet demand for wireless
and local phone service, high population density in the island's metropolitan
areas, a growing economy and a stable business environment.
 
      Centennial de Puerto Rico offers wireless and wireline services using a
shared Lucent Technologies 5 ESS switch and its sophisticated fiber optic
network, which contains over 314 route miles of fiber throughout the island of
Puerto Rico. The digital personal communications services network allows for
coverage in most areas of Puerto Rico using its established base of 120 cell
sites and CDMA technology to transmit its calls.
 
     .  Wireless Services. Centennial de Puerto Rico offers both personal
        communications services and wireless local loop service to its
        customers. Our personal communications services business
 
                                       52
<PAGE>
 
        currently covers approximately 85% of the total Pops on the island
        of Puerto Rico and targets high volume users. We began offering
        personal communication services, in December 1996 and as of February
        28, 1999 had approximately 99,600 subscribers, an increase of 83%
        over our approximately 54,500 subscribers at February 28, 1998. Our
        total average revenue per personal communications services customer
        was approximately $89 during the nine months ended February 28,
        1999, compared to approximately $46 for the average U.S. wireless
        customer for the nine months ended September 30, 1998, according to
        data from the CTIA. Centennial de Puerto Rico began offering
        wireless local loop service to business and residential customers in
        August 1997. Our total average revenue per wireless local loop
        customer was $94 during the nine months ended February 28, 1999.

     .  Wireline Services. Lambda CLEC provides local, long distance and
        enhanced data services (including internet-related services) to
        business and government customers over our high bandwidth, fiber
        optic network. We believe that our targeted competitive local
        exchange carrier customers have sophisticated communications service
        requirements, including the need for a reliable network providing
        data access and private line services and high quality customer
        service. Lambda CLEC has grown rapidly since its inception in
        September 1997, primarily due to its ability to offer a broad range
        of products as well as responsive and reliable service in an
        underserved market. Lambda CLEC provided approximately 56.9 million
        MOUs to its customers in February 1999, an increase of 90% over the
        minutes of use provided in May 1998.
 
      Since operations commenced in December 1996, Centennial de Puerto Rico
has achieved significant growth in subscribers, revenue and EBITDA, which we
attribute to our premium service capabilities, experienced local management
team and limited competition in the region. Revenue for the fiscal year ended
May 31, 1998 was $54.6 million, compared to $5.9 million for the year ended
May 31, 1997. EBITDA for the fiscal year ended May 31, 1998 was $12.5 million,
compared to an EBITDA deficit of $(8.4) million for the prior period. Revenue
for the nine months ended February 28, 1999 was $87.6 million. EBITDA for the
nine months ended February 28, 1999 was $38.8 million or $51.8 million on an
annualized basis.

will automatically renew for subsequent one-year terms unless either party
gives notice of non-renewal at least 90 days prior to the expiration of the
renewal term. If Centennial terminates Mr. Small's employment for other than
"cause" (as defined in the employment agreement), or if Mr. Small terminates
his employment with Centennial for "Good Reason" (as defined in the employment
agreement), he is entitled to continue to receive his base salary and any bonus
payable with respect to the one-year period following such termination, as well
as certain other benefits. Mr. Small also received incentive stock options and
non-qualified stock options to purchase an aggregate 135,000 Centennial common
shares (prior to adjustment to account for a three-for-one stock split),
vesting over four years beginning with the fiscal year ended May 31, 1999 if
Centennial attains certain EBITDA targets; if such targets are not met, the
stock options will vest over four years commencing with the seventh anniversary
of the consummation of the merger. These stock options are subject to
accelerated vesting if Mr. Small's employment is terminated other than for
cause or for Good Reason following a change of control of Centennial. During
the employment term and for a period of one year following the termination of
his employment (except termination by Mr. Small for Good Reason), Mr. Small is
subject to certain non-competition and non-solicitation provisions.
 
      After the merger, Rudy J. Graf has been employed by Centennial de Puerto

Centennial terminates Mr. Graf's employment for other than "cause" (as defined
in the employment agreement), he is entitled to receive his base salary for the
remainder of the employment term, any bonus payable for the 1999 fiscal year
and certain other payments. At the effective time of the merger, Mr. Graf
received 17,242 Centennial common shares (prior to adjustment to account for a
three-for-one stock split) subject to the terms of a restricted stock purchase
agreement. Mr. Graf also received incentive stock options and non-qualified
stock options to purchase an aggregate 130,000 Centennial common shares (prior
to adjustment to account for a three-for-one stock split), vesting over four
years beginning with the fiscal year ended May 31, 1999 if Centennial attains
certain EBITDA targets; if such targets are not met, the stock options will
vest over four years commencing with the seventh anniversary of the
consummation of the merger. During the employment term and for a period of two
years following the termination of his employment, Mr. Graf is subject to
certain non-competition and non-solicitation provisions.
 
      After the merger, Peter Chehayl has been employed by Centennial as its
Senior Vice President and Chief Financial Officer. Mr. Chehayl's base salary
will be $165,000 per annum, plus an annual bonus of up to $90,000. He is also

<PAGE>
 
      Centennial. During the fiscal year ended May 31, 1998, each director who
was not also an employee of Centennial received quarterly retainers of $3,000
plus a uniform fee of $750 for each Board and committee meeting attended. In
addition, options for 1,000 shares of Centennial common shares were
automatically granted under the 1993 Non-Employee/Officer Directors' Stock
Option Plan to each person who was a non-employee/officer director on the date
of each annual meeting of shareholders of Centennial. During such period,
directors who were also employees of Centennial received no remuneration for
attendance at Board and committee meetings.
 
      After the merger, each director who is not also an employee of
Centennial will receive compensation in accordance with the Welsh Carson
VIII's and Blackstone's customary practices. Centennial expects that such
compensation will be consistent with compensation paid to directors in
comparable public companies.

                             PRINCIPAL STOCKHOLDERS
 
      After the merger and related transactions, all of the issued and
outstanding capital stock of Centennial Cellular Operating is owned by
Centennial. The table below contains information regarding the beneficial
ownership of Centennial's common shares immediately following the consummation
of the merger and related transactions by (i) each stockholder who owns
beneficially five percent or more of Centennial's common shares, (ii) each
director of the Centennial, (iii) each executive officer and (iv) all directors
and officers as a group.
 
      The number of shares beneficially owned by each stockholder, director or
officer is determined according to the rules of the SEC, and the information is
not necessarily indicative of beneficial ownership for any other purpose. Under
such rules, beneficial ownership includes any shares as to which the individual
or entity has sole or shared voting power or investment power. As a
consequence, several persons may be deemed to be the "beneficial owners" of the
same shares. Unless otherwise noted in the footnotes to this table, each of the
stockholders named in this table has sole voting and investment power with
respect to the Centennial common shares shown as beneficially owned. The
percentage ownership of each stockholder is calculated based on 31,125,579
common shares outstanding (after giving effect to a three-for-one stock split
effected on January 8, 1999).

      In connection with their initial investment in CCW Acquisition Corp. and
the common equity contribution and simultaneously with the consummation of the
merger, the equity investors and CCW Acquisition Corp. entered into a
securities purchase agreement, a registration rights agreement and a
stockholders agreement.
 
      Pursuant to the securities purchase agreement, the equity investors
purchased an aggregate of 9,638,554 shares of common stock of CCW Acquisition
Corp. at the time of the merger. The securities purchase agreement contains
customary conditions, representations and warranties, and will terminate upon
the termination of the merger agreement.
 
      At the same time, the equity investors and Centennial entered into a
stockholders' agreement pursuant to which they agreed to establish a board of
directors of Centennial consisting of nine members. Welsh Carson and certain of
its affiliates will designate three of such directors, who initially are Thomas
E. McInerney, Anthony J. de Nicola and Rudolph E. Rupert, so long as Welsh
Carson and those affiliates own in the aggregate at least 25% of the shares of
Centennial owned by them as of the date of the merger. Blackstone and its
affiliates will designate two directors, who initially are Mark T. Gallogly and
Lawrence H. Guffey, so long as Blackstone and those affiliates own in the
aggregate at least 25% of the shares of the surviving corporation owned by them
as of the date of the merger. The Chief Executive Officer and the Chief
Operating Officer of Centennial, who initially are Michael J. Small and Rudy
Graf, respectively, will also be directors. The remaining two directors will be
outside directors nominated by the board of directors and elected by
stockholders of Centennial, including the equity investors. Pursuant to the
stockholders' agreement, the equity investors (other than Welsh Carson and its
affiliates) also have "tag-along" rights to participate in certain proposed
dispositions of the Centennial's shares by the Welsh Carson and its affiliates.
In addition, in the event that Welsh Carson and its affiliates or Centennial
receives a third party offer to purchase at least 80% of the outstanding
capital stock of Centennial, a majority of Welsh Carson and its affiliates may
require the other equity investors to accept such offer and to sell their
shares of Centennial to the third party. Centennial has also granted the equity
investors pre-emptive rights with respect to participating, on a pro rata basis
according to their stock ownership, in certain eligible offerings (excluding
registered public offerings of Centennial common shares and offerings of
Centennial common shares or options to purchase Centennial common shares in
connection with certain stock option plans or stock purchase plans). While the
stockholders' agreement is in effect, Centennial may not amend, alter or repeal
its organizational documents without obtaining the consent of a majority in
interest of Welsh Carson and its affiliates and Blackstone and its affiliates,
as well as a majority of the other equity investors adversely affected by such
amendment or alteration. Further, the stockholders' agreement contains certain
restrictions on transactions with related persons. Upon the consummation of the
merger and related transactions, an affiliate of each of Welsh Carson and
Blackstone received a deal consummation fee of $10.6 million and $3.4 million,
respectively. An equity investor unaffiliated with Blackstone and Welsh Carson
and its affiliates received a fee of $4.0 million upon the consummation of the
merger. During the term of the stockholders' agreement, an affiliate of each of
Welsh Carson and Blackstone will receive an annual monitoring fee of $450,000
and $300,000, respectively.
 
      Pursuant to the registration rights agreement entered into among
Centennial and the equity investors, the Welsh Carson and its affiliates and
Blackstone and its affiliates have certain rights to require Centennial to
register their shares of Centennial under the Securities Act and to include,
upon request, their shares in any registration of shares effected by
Centennial.
 
Former Indebtedness of Certain Executive Officers
 
      During fiscal 1998, Thomas R. Cogar, Vice President of Engineering of
Centennial received a relocation loan from Centennial of approximately $65,000
and John H. Casey, Vice President--Administration
 
                                       61
<PAGE>
 
of Centennial received a relocation and temporary house loan of approximately
$200,000. There are no amounts outstanding under these loans.
 
Arrangements with Former Controlling Stockholder
 
      Pursuant to the stockholder's agreement, on the effective date of the
merger, Century executed and delivered a non-compete agreement with Centennial,
in which Century agreed that, for a period of three years from the effective
date of the merger, it will not engage in, or acquire a controlling interest
in, any business that competes with any of the businesses of Centennial's
current operations in Puerto Rico; provided, however, that such non-compete
shall not extend to or restrict in any manner the activities of Century's
existing joint venture in Puerto Rico, Century-ML.
 
      Centennial and Century, which owned a controlling interest in Centennial
prior to the merger, previously maintained combined workers compensation and
general insurance policies. The premiums were allocated between Centennial and
Century based upon the actual cost of each respective company's coverage.
Centennial believes that the amounts payable by Centennial under such
arrangement were more favorable than the premiums Centennial would have paid if
it had obtained coverage under a separate policy. Centennial's cost of such
insurance was approximately $0.6 million, $0.7 million and $1.7 million for the
fiscal years ended May 31, 1998, 1997 and 1996, respectively, all of which was
paid in full during the current fiscal year. In fiscal 1996, Centennial and
Century also maintained combined group health, life and casualty coverage.
Pursuant to the merger agreement, Centennial has covenanted to maintain for a
period of at least two years employee benefits and incentive compensation that
are no less favorable to its employees.
 
      Centennial and Century entered into a services agreement, effective
August 30, 1996, pursuant to which Century, through its personnel, provides
design, construction, management, operational, technical and maintenance for
the wireless telephone, paging and related systems owned and operated by
Centennial. Such services also include providing all the services necessary for
the monitoring, to the extent possible, of the activities of the partnerships
in which Centennial has minority equity interests, in such manner as to protect
the interests of Centennial. Such services have historically been provided to
Centennial by Century. As consideration for the services rendered under the
services agreement, Centennial paid Century the annual sum of $1.0 million and
reimbursed Century for all costs incurred by Century or its affiliates
(excluding Centennial and its subsidiaries) that were directly attributable to
the design, construction, management, operation and maintenance of the wireless
telephone, paging and related systems of Centennial or to the performance by
Century of its other duties under the services agreement. For the years ended
May 31, 1998 and 1997, Centennial recorded expenses of $1.0 million and $0.8
million, respectively, under the services agreement. At May 31, 1998 and 1997,
$0.3 million and $0.8 million, respectively, of such amounts were recorded
within Payable to Affiliate on Centennial's consolidated balance sheet. As of
the effective time of the merger, Century and Centennial terminated the
services agreement.
 
      Centennial leases space for the mobile telephone switching office serving
the southwestern cluster and space on an antenna tower in the southwestern
cluster from Century for an aggregate current annual rent of approximately
$1,000 pursuant to an oral month-to-month lease agreement. Further, Centennial
leases certain warehouse space in Puerto Rico to Century-ML for a current
annual rent of approximately $23,000 pursuant to a written lease agreement.
Centennial leases and shares capacity on the fiber optic cable television
facility and network of Century-ML fiber network for the purposes of operating
as a competitive access provider. Centennial shares the cost of construction,
operation and maintenance of the Century-ML fiber network on a pro rata basis
based on the percentage of the number of fibers of the network used by or
reserved for Centennial.
 
      During fiscal 1997, Centennial recorded a deferred asset and related
payable to an affiliate in its consolidated balance sheet in the amount of $6.0
million to reflect certain costs incurred by Centennial to secure the use of
the fiber optic network as required by the facilities agreement. This amount,
which was paid
 
                                       62
<PAGE>
 
by Centennial during fiscal 1998, represents Centennial's share of the costs of
constructing Century-ML's fiber optic network.
 
      Leavy Rosensweig & Hyman, of which David Z. Rosensweig, a director and
Secretary of Centennial prior to the merger, is a member, provides legal
services to Centennial.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
The Credit Facility
 
      In connection with the Merger, Centennial and some of its subsidiaries
entered into the credit facility with Merrill Lynch Capital Corporation,
NationsBank, N.A., The Chase Manhattan Bank, The Bank of Nova Scotia and Morgan
Stanley Senior Funding, Inc. (collectively with Merrill Lynch Capital,
NationsBank, Chase and Scotia, the "Agents") and certain other financial
institutions (collectively, with the Agents, the "Lenders"), pursuant to which
the Lenders provided credit facilities to certain of Centennial's subsidiaries.
The following is a summary of the proposed terms and conditions of each credit
facility.
 
      The Borrowers. The borrowers under the credit facility are Centennial
Cellular Operating, a wholly owned direct subsidiary of Centennial, and
Centennial de Puerto Rico, a wholly owned direct subsidiary of Centennial
Cellular Operating.
 
      The Facility. The credit facility provides for a senior secured revolving
credit facility, which provides revolving loans in an aggregate principal
amount of up to the Lenders' revolving credit commitment, which will initially
be $150 million (of which a sublimit thereof will be available to be borrowed
by Centennial de Puerto Rico), and senior secured term loan facilities in four
tranches, which provide term loans in an aggregate principal amount of up to
$900 million (of which one tranche thereof is available to be drawn by
Centennial de Puerto Rico).
 
      Use of Credit Facility Proceeds. The proceeds of the credit facility were
used, together with other proceeds of the Merger Financings, to fund payment of
cash consideration in the merger, repay Centennial's indebtedness (including
the purchase of the tendered notes in the debt tender offers), pay the related
fees and expenses and purchase the pledged securities. In addition, the
revolving credit facility is available after the closing of the revolving
credit facility subject to the conditions set forth in the credit facility
documentation to finance future working capital needs, capital expenditures,
permitted acquisitions, and for general corporate purposes.
 
      Under certain circumstances, the credit facility may be increased by up
to $150 million in aggregate principal amount, upon terms and conditions no
more onerous than those contained in the credit facility.
 
      Availability of Loans. The term loans were available on the date of
closing of the merger. The revolving credit loans were available on the date of
closing of the merger in a principal amount not to exceed $65 million and
thereafter on a revolving basis until 30 days prior to the maturity thereof. Up
to $25 million of the revolving credit facility is available for the issuance
of letters of credit and up to $30 million of the Revolving Credit Facility
will be available for swing loans.
 
      Maturity of Loans. The revolving credit commitments will be reduced
quarterly beginning in the fourth year after the closing of the credit facility
and the revolving credit facility will mature eight years after the closing of
the credit facility. The term loans will consist of four tranches and will
amortize over eight years for tranche A term loans, eight years for tranche A-
PR term loans, eight and one-half years for tranche B term loans and nine years
for tranche C term loans.
 
      Prepayments. Borrowings and commitments under the credit facility are
subject to mandatory prepayment and reduction in an amount equal to (a) 100% of
the net proceeds of asset dispositions (including insurance proceeds resulting
from casualty to assets), subject to the borrower's ability to reinvest such
proceeds under certain circumstances, (b) 75% of excess cash flow (reduced to
50% with respect to any fiscal year if the Total Leverage Ratio (defined as the
ratio of total debt to operating cash flow) is less than 6.0:1.0), (c) 100% of
the net proceeds of the issuance or incurrence of debt or of any sale and
lease-back, and (d) 50% of the net proceeds of any issuance of equity
securities. Voluntary prepayment of the loans will be permitted in whole or
 
                                       64
<PAGE>
 
in part with prior notice. The revolving credit loans and the tranche A and
tranche A-PR loans are subject to prepayment without premium or penalty (other
than funding losses), subject to limitations as to minimum amounts. The tranche
B and tranche C loans are subject to prepayment (x) on or prior to the first
anniversary of the closing of the credit facility, with a premium of 2% of the
aggregate principal amount of loans prepaid, (y) after the first anniversary of
the closing of the credit facility and on or prior to the second anniversary of
the closing of the credit facility, with a premium of 1% of the aggregate
principal amount of loans prepaid and (z) thereafter, without premium or
penalty (other than funding losses), subject to limitations as to minimum
amounts.
 
      Interest Rates. Borrowings under the credit facility bear interest at a
rate per annum of, at the borrowers' option, either (a) a base rate (defined as
the higher of (i) the announced prime rate of NationsBank, and (ii) the federal
funds rate, plus 0.50%) plus the Applicable Margin (as defined) or (b) a LIBOR
rate plus the Applicable Margin. The maximum Applicable Margin for the tranche
A loans, tranche A-PR loans and the revolving credit loans is 2.00% for base
rate loans and 3.00% for LIBOR loans, for the tranche B loans will be 2.50% for
base rate loans and 3.50% for LIBOR loans, and for the tranche C loans will be
2.75% for base rate loans and 3.75% for LIBOR loans. Based upon Centennial
Cellular Operating's leverage ratio after the delivery of certain financial
statements after the closing of the credit facility, the Applicable Margin for
tranche A loans, tranche A-PR loans and revolving credit loans may be reduced
by up to 1.250% for base rate loans and LIBOR loans. The default rate under the
credit facility is 2.00% above the otherwise applicable rate.
 
      Fees and Expenses. The credit facility requires the borrower to pay (a)
commitment fees to the Lenders in an amount equal to 0.50% or 0.375% per annum
on the unused commitment under the revolving credit facility, depending on
Centennial Cellular Operating's leverage ratio, and (b) an annual
administrative agent's fee. Additionally, the borrowers paid various fees and
costs in connection with the credit facility, including commitment fees and
underwriting fees to Merrill Lynch Capital, NationsBank, Chase, Nova Scotia,
and Morgan Stanley.
 
      Guarantees. Centennial and each of Centennial Cellular Operating's direct
and indirect existing and future subsidiaries (other than foreign subsidiaries)
will be required to guarantee Centennial Cellular Operating's obligations under
the credit facility, and Centennial Cellular Operating and Centennial de Puerto
Rico's direct and indirect existing and future subsidiaries were required to
guarantee Centennial de Puerto Rico's obligations under the credit facility.
 
      Security. The obligations of Centennial Cellular Operating under the
credit facility are secured by substantially all of the assets of Centennial
and each of its direct and indirect existing and future subsidiaries (other
than foreign subsidiaries), including the capital stock of such subsidiaries,
and the obligations of Centennial de Puerto Rico under the credit facility are
secured by substantially all of the assets of Centennial de Puerto Rico and
each of its direct and indirect existing and future subsidiaries, including the
capital stock of such subsidiaries.
 
      In addition, Centennial guaranteed the credit facility and pledged as
security for Centennial Cellular Operating's obligations the capital stock of
Centennial Cellular Operating to the Lenders under the credit facility. The
pledge of such capital stock of Centennial Cellular Operating could impair
Centennial Cellular Operating's ability to obtain future financing on favorable
terms, if at all. Further, in the event Centennial Cellular Operating were to
default on its obligations under the credit facility and the Lenders were to
foreclose upon such pledged capital stock of Centennial Cellular Operating,
Centennial, as the holding company of Centennial Cellular Operating, would
likely be unable to service or repay its indebtedness, including the notes.
 
      Conditions. Various conditions precedent to borrowings under the credit
facility on the date of closing of the merger were satisfied.
 
                                       65

      Representations and Warranties. The credit facility contains
representations and warranties customarily found in loan agreements for similar
financings.
 
      Affirmative Covenants.  The credit facility contains affirmative
covenants customarily found in loan agreements for similar financings.
Centennial Cellular Operating is required to enter into interest rate hedging
agreements with respect to 50% of the indebtedness under the credit facility
for a period of time satisfactory to the Lenders.
 
      Negative Covenants.  The credit facility contains customary restrictive
covenants, including covenants that limit (subject to certain exceptions) the
ability of the Centennial Cellular Operating and its subsidiaries to:
 
     .  incur indebtedness or contingent obligations, issue guarantees or
        enter into operating leases,
 
     .  grant liens or negative pledges,
 
     .  make investments or enter into joint ventures,
 
     .  make certain restricted payments,
 
     .  make fundamental changes in their business, corporate structure or
        capital structure,
 
     .  sell assets or receivables,
 
     .  make capital expenditures,
 
     .  enter into transactions with affiliates,
 
     .  amend documents relating to other existing indebtedness and other
        material documents, or
 
     .  prepay other indebtedness.
 
      Financial Covenants. The credit facility contains financial covenants
relating to:
 
     .  minimum interest coverage ratio,
 
     .  minimum fixed charge coverage ratio,
 
     .  maximum ratio of total debt to operating cash flow,
 
     .  maximum ratio of senior debt to operating cash flow,
 
     .  minimum pro forma debt service coverage ratio, and
 
     .  limitation on capital expenditures.
 
      Events of Default. The credit facility includes standard events of
default, including, subject to certain exceptions, those related to:
 
     .  default in the payment of principal and interest,
 
     .  cross-default in payment of other indebtedness of more than $10.0
        million,
 
     .  materially incorrect representations and warranties,
 
     .  default in the observance or performance of any of the affirmative
        or negative covenants included in the credit facility documentation
        or in the related security and pledge documents,
 
     .  the failure to or admission in writing of an inability to pay debts
        when such debts become due,
 
     .  certain events of bankruptcy,
 
                                       66
<PAGE>
 
     .  certain judgments or decrees involving more than $10.0 million,
 
     .  certain ERISA events,
 
     .  a Change of Control (as defined in the credit facility),
 
     .  the failure of the applicable credit facility documents or any
        material provision thereof, the guarantees, security documents or
        any related documents to be in full force and effect,
 
     .  certain non-monetary judgments or decrees which might have a
        material effect,
 
     .  the termination, revocation or nonrenewal of one or more cellular
        licenses if such termination, revocation or nonrenewal will have a
        material effect, and
 
     .  the failure of the merger to be consummated substantially concurrent
        with the extension of credit under the credit facilities.
 
Subordinated Debt
 
      As part of the mezzanine financing, WCAS Capital Partners III, L.P., an
investment partnership affiliated with Welsh Carson VII, purchased at the time
of the consummation of the merger, a Senior Subordinated Note of Centennial due
2009 (the "Senior Subordinated Note") in the original principal amount of $180
million, as well as an agreed upon number of Centennial common shares, for an
aggregate cash purchase price of $180 million. The Senior Subordinated Note
bears cash interest at a rate of 10% or pay-in-kind interest at a rate of 13%
per annum. Centennial Cellular Operating is restricted from making cash
payments to Centennial to service the debt under certain circumstances under
the notes and the credit facility. See "Description of the New Notes--Certain
Covenants--Limitation on Restricted Payments."
 
      The Senior Subordinated Note is prepayable at Centennial's option and
must (subject to the terms of the indenture for the notes and the credit
facility) be prepaid in the event of a "Change in Control," defined as:
 
     .  the acquisition by a person or group acting together (other than the
        equity investors and their affiliates) of either at least 50% of the
        voting stock of Centennial or sufficient voting power to elect a
        majority of the Board of Directors,
 
     .  a merger or consolidation of Centennial as a result of which the
        stockholders of Centennial do not continue to hold a majority of the
        voting capital stock of the resulting entity, or
 
     .  the sale by Centennial of substantially all of its assets.
 
      The Senior Subordinated Note contains certain affirmative and negative
covenants typically found in subordinated notes. The Senior Subordinated Note
may not be transferred without the consent of the Lenders under the credit
facility or, during the period ending 180 days after the closing of the
offering of the notes, without the consent of Merrill Lynch on behalf of the
initial purchasers of the notes.
 
      The Senior Subordinated Note is subordinate in right of payment to the
notes to the extent set forth in the Senior Subordinated Note. Under the Senior
Subordinated Note, Centennial may not make any payments thereon if there is a
default under any "Senior Indebtedness" which is defined to include the notes.
If an "Event of Default" occurs under the Senior Subordinated Note (except in
connection with certain bankruptcy events), the holder of the Senior
Subordinated Note may not accelerate such debt unless the indebtedness under
the notes and the credit facility have been accelerated for at least 90 days.
The Senior Subordinated Note is also subordinate to the credit facility to the
same extent.

                          DESCRIPTION OF THE NEW NOTES
 
Introduction to the Indenture
 
      The outstanding notes were, and the new notes will be, issued under an
Indenture dated as of December 14, 1998 among Centennial Cellular Operating Co.
LLC, as the Issuer, Centennial Cellular Corp., as successor to Centennial
Finance Corp., as a co-obligor, and Norwest Bank Minnesota, N.A., as trustee, a
copy of which is available from Centennial. Upon the effectiveness of the
registration statement, of which this prospectus is a part, the indenture will
be subject to and governed by the Trust Indenture Act of 1939, as this Act may
have been amended. The summary of the material provisions of the indenture in
this "Description of the New Notes" section includes all material information
with regard to those provisions. For definitions of certain capitalized terms
used in this "Description of the New Notes" section, see the discussion under
the "Certain Definitions" heading below. For purposes of this section, the term
"Issuer" means Centennial Cellular Operating Co. LLC without its subsidiaries
and the term "Centennial" means Centennial Cellular Corp. without its
subsidiaries. For purposes of this section, the term "Co-Obligors" means the
Issuer and Centennial, in each case without their respective subsidiaries.
 
General Terms of the Notes
 
      The new notes:
 
     .  will be senior subordinated obligations of the Co-Obligors limited
        to $370 million aggregate principal amount,
 
     .  will be issued at par,
 
     .  will mature on December 15, 2008,
 
     .  will bear interest at the rate per annum stated on the cover page
        hereof from December 14, 1998 or from the most recent Interest
        Payment Date to which interest has been paid or provided for,
        payable semi-annually in arrears on June 15 and December 15 of each
        year (each, an "Interest Payment Date"), commencing June 15, 1999 to
        the Persons in whose names such new notes are registered at the
        close of business on June 1 or December 1 preceding such Interest
        Payment Date,
 
     .  will accrue interest from the most recent Interest Payment Date to
        which interest has been paid or duly provided for on the old note
        surrendered in exchange for such new note, or, if no interest has
        been paid or duly provided for on such old note, from December 14,
        1998, and
 
     .  will be issued only in fully registered form, without coupons, in
        denominations of $1,000 and integral multiples thereof.
 
      Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months.
 
      The Indenture does not contain provisions which would afford holders of
the new notes protection in the event of a decline in the Co-Obligors' credit
quality resulting from highly leveraged or other similar transactions involving
the Co-Obligors.
 
      Principal of, premium, if any, and interest on the new notes will be
payable, and, subject to the following provisions, the new notes may be
presented for registration of transfer or exchange, at the office or agency of
the Co-Obligors maintained for such purpose, which office or agency shall be
maintained in the Borough of Manhattan of The City of New York. At the option
of the Co-Obligors, payment of interest may be made by check mailed to the
holders of the new notes at the addresses set forth upon the registry books of
the Co-Obligors. No service charge will be made for any registration of
transfer or exchange of new notes, but the Co-Obligors may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
 
                                       68
<PAGE>
 
connection therewith. Until otherwise designated by the Co-Obligors, the Co-
Obligors' office or agency will be the corporate trust office of the Trustee
presently located in New York, New York.
 
      Settlement for the new notes will be made in same day funds. All payments
of principal and interest will be made by the Co-Obligors in same day funds.
The new notes will trade in the Same-Day Funds Settlement System of The
Depository Trust Company (the "Depositary" or "DTC") until maturity, and
secondary market trading activity for the new notes will therefore settle in
same day funds.
 
      When issued, the new notes will be a new issue of securities with no
established trading market. We cannot assure you that there will be a liquid
trading market for the notes. See "Risk Factors--Absence of Public Trading
Market for the New Notes."
 
Ranking
 
      The payment of the principal of, premium, if any, and interest on, the
new notes will be subordinated, as set forth in the indenture, in right of
payment, to the prior payment in full of all Senior Indebtedness. The new notes
will be senior subordinated indebtedness of the Issuer ranking pari passu with
all other existing and future senior subordinated indebtedness of the Issuer
and senior to all existing and future Subordinated Indebtedness of the Issuer.
 
      In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding
in connection therewith, relating to the Issuer or to its assets, or any
liquidation, dissolution or other winding-up of the Issuer, whether voluntary
or involuntary and whether or not involving insolvency or bankruptcy, or any
assignment for the benefit of creditors or their marshalling of assets or
liabilities of the Issuer (except in connection with the consolidation or
merger of the Issuer or its liquidation or dissolution following the
conveyance, transfer or lease of its properties and assets substantially as an
entirety upon the terms and conditions described under "Certain Covenants--
Limitation on Merger, Sale or Consolidation" below), the holders of Senior
Indebtedness will be entitled to receive payment in full in cash or cash
equivalents of all Senior Indebtedness, or provision will be made for such
payment in full, before the holders of new notes will be entitled to receive
any payment or distribution of any kind or character (other than any payment or
distribution in the form of equity securities or subordinated securities of the
Issuer or any successor obligor that, in the case of any such subordinated
securities, are subordinated in right of payment to all Senior Indebtedness
that may at the time be outstanding to at least the same extent as the new
notes are so subordinated (such equity securities or subordinated securities
hereinafter being "Permitted Junior Securities") and any payment made pursuant
to the provisions described under "--Legal Defeasance and Covenant Defeasance"
from monies or U.S. Government Obligations (as defined in the Indenture)
previously deposited with the Trustee on account of principal of, or premium,
if any, or interest on the new notes); and any payment or distribution of
assets of the Issuer of any kind or character, whether in cash, property or
securities (other than a payment or distribution in the form of Permitted
Junior Securities and payments made pursuant to the provision described under
"--Legal Defeasance and Covenant Defeasance" from monies or U.S. Government
Obligations previously deposited with the Trustee), by set-off or otherwise, to
which the holders of the new notes or the Trustee would be entitled but for the
provisions of the Indenture shall be paid by the liquidating trustee or agent
or other person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Senior Indebtedness or their representative or representatives
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness to the extent necessary to make payment in full of all
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution to the holders of such Senior Indebtedness.
 
      No payment or distribution of any assets of the Issuer of any kind or
character, whether in cash, property or securities (other than Permitted Junior
Securities and payments made pursuant to the provisions described under "--
Legal Defeasance and Covenant Defeasance" from monies or U.S. Government
Obligations previously deposited with the Trustee), may be made by or on behalf
of the Issuer on account of
 
                                       69

principal of, premium, if any, or interest on the new notes or on account of
the purchase, redemption or other acquisition of new notes:
 
     .  upon the occurrence of any default in payment (whether at stated
        maturity, upon scheduled installment, by acceleration or otherwise)
        of principal of, premium, if any, or interest on Designated Senior
        Indebtedness (as defined below) (a "Payment Default") until such
        Payment Default shall have been cured or waived in writing or shall
        have ceased to exist or such Designated Senior Indebtedness shall
        have been discharged or paid in full in cash or cash equivalents,
 
     .  for the period specified below (a "Payment Blockage Period") upon
        the occurrence of any default or event of default with respect to
        any Designated Senior Indebtedness other than any Payment Default
        pursuant to which the maturity thereof may be accelerated (a "Non-
        Payment Default") and receipt by the Trustee of written notice
        thereof from the agent bank under the Credit Facility (the "Agent
        Bank") or other representative of holders of Designated Senior
        Indebtedness.
 
      The Payment Blockage Period will commence upon the date of receipt by the
Trustee of written notice from the Agent Bank or such other representative of
the holders of the Designated Senior Indebtedness in respect of which the Non-
Payment Default exists and shall end on the earliest of:
 
     (1) 179 days thereafter (provided that any Designated Senior
         Indebtedness as to which notice was given shall not theretofore
         have been accelerated),
 
     (2) the date on which such Non-Payment Default is cured, waived or
         ceases to exist or such Designated Senior Indebtedness is
         discharged or paid in full in cash or cash equivalents, or
 
     (3) the date on which such Payment Blockage Period shall have been
         terminated by written notice to the Trustee or the Issuer from the
         Agent Bank or such other representative initiating such Payment
         Blockage Period, after which the Issuer will resume making any and
         all required payments in respect of the notes, including any missed
         payments.
 
In any event, not more than one Payment Blockage Period may be commenced during
any period of 365 consecutive days, and there must be at least 186 consecutive
days in every 365 day period during which there is no Payment Blockage Period.
No event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period will be, or can be made, the basis
for the commencement of a subsequent Payment Blockage Period, unless such
default has been cured or waived for a period of not less than 90 consecutive
days subsequent to the commencement of such initial Payment Blockage Period.
 
      In the event that, notwithstanding the provisions of the preceding four
paragraphs, any payment shall be made to the Trustee which is prohibited by
such provisions, then and in such event such payment shall be paid over and
delivered by such Trustee to the Agent Bank and any other representative of
holders of Designated Senior Indebtedness, as their interests may appear, for
application to Designated Senior Indebtedness. After all Senior Indebtedness is
paid in full and until the new notes are paid in full, holders of the new notes
shall be subrogated (equally and ratably with all other Indebtedness pari passu
with the new notes, including the old notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the new notes
have been applied to the payment of Senior Indebtedness.
 
      Failure by the Issuer to make any required payment in respect of the new
notes when due and within any applicable grace period, whether or not occurring
during a Payment Blockage Period, will result in an Event of Default under the
Indenture and, therefore, holders of the new notes will have the right to
accelerate the maturity thereof. See "--Events of Default."

<PAGE>
 
      By reason of such subordination, in the event of liquidation,
receivership, reorganization or insolvency of the Issuer, creditors of the
Issuer who are holders of Senior Indebtedness may recover more, ratably, than
the holders of the new notes, and assets which would otherwise be available to
pay obligations in respect of the new notes will be available only after all
Senior Indebtedness has been paid in full in cash or cash equivalents, and
there may not be sufficient assets remaining to pay amounts due on any or all
of the new notes.
 
      "Senior Indebtedness" means the principal of, premium, if any, and
interest (including interest, to the extent allowable, accruing after the
filing of a petition initiating any proceeding under any state, federal or
foreign bankruptcy law) on any Indebtedness of the Issuer (other than as
otherwise provided in this definition), whether outstanding on the date of the
Indenture or thereafter created, incurred or assumed, and whether at any time
owing, actually or contingent, unless, in the case of any particular
Indebtedness, the instrument creating or evidencing the same or pursuant to
which the same is outstanding expressly provides that such Indebtedness shall
not be senior in right of payment to the new notes. Notwithstanding the
foregoing, "Senior Indebtedness" shall not include:
 
    (1) Indebtedness evidenced by the new notes,
 
    (2) Indebtedness that is subordinate or junior in right of payment to
        any Indebtedness of the Issuer,
 
    (3) Indebtedness which when incurred and without respect to any election
        under Section 1111(b) of Title 11 United States Code, is without
        recourse to the Issuer,
 
    (4) Indebtedness which is represented by Disqualified Capital Stock,
 
    (5) any liability for foreign, federal, state, local or other taxes owed
        or owing by the Issuer to the extent such liability constitutes
        Indebtedness,
 
    (6) Indebtedness of the Issuer to a Subsidiary or any other Affiliate of
        the Issuer or any of such Affiliate's Subsidiaries,
 
    (7) to the extent it might constitute Indebtedness, amounts owing for
        goods, materials or services purchased in the ordinary course of
        business or consisting of trade accounts payable owed or owing by
        the Issuer, and amounts owed by the Issuer for compensation to
        employees or services rendered to the Issuer,
 
    (8) that portion of any Indebtedness which at the time of issuance is
        issued in violation of the Indenture, and
 
    (9) Indebtedness evidenced by any guarantee of any Subordinated
        Indebtedness or Pari Passu Indebtedness.
 
      "Designated Senior Indebtedness" means:
 
    (1) all Senior Indebtedness under the Credit Facility, and
 
    (2) any other Senior Indebtedness which at the time of determination has
        an aggregate principal amount outstanding of at least $25 million
        and which is specifically designated in the instrument evidencing
        such Senior Indebtedness or the agreement under which such Senior
        Indebtedness arises as "Designated Senior Indebtedness" by the
        Issuer.
 
      The indenture will limit, but not prohibit, the incurrence by the Issuer
and its Subsidiaries of additional Indebtedness, and the indenture will
prohibit the incurrence by the Issuer of Indebtedness that is subordinated in
right of payment to any Senior Indebtedness of the Issuer and senior in right
of payment to the new notes.
 
      The new notes will rank junior to all Senior Indebtedness of the Issuer,
equal in right of payment to all future senior subordinated indebtedness of the
Issuer and senior to all Subordinated Indebtedness of the Issuer. As of
February 28, 1999, the Issuer had:
 
 
                                       71
<PAGE>
 
     .  $933.9 million in aggregate principal amount of Senior Indebtedness
        outstanding, and
 
     .  $370 million in aggregate principal amount of senior Subordinated
        Indebtedness representing the notes. See "Unaudited Pro Forma
        Financial Information."
 
      The Issuer conducts its operations through its Subsidiaries. Accordingly,
the Issuer's ability to meet its cash obligations is dependent upon the ability
of its Subsidiaries to make cash distributions to the Issuer. Dividends from
the Issuer's Subsidiaries are expected to be the only source for payment of
interest on the new notes after the first three interest payments (which will
be satisfied from the Pledged Securities). Furthermore, any right of the Issuer
to receive the assets of any of its Subsidiaries upon any such Subsidiary's
liquidation (and the consequent right of the Holders of the new notes to
participate in the distribution of the proceeds of those assets) effectively
will be subordinated by operation of law to the claims of such Subsidiary's
creditors (including trade creditors) and holders of its preferred stock, if
any, except to the extent that the Issuer is itself recognized as a creditor or
preferred stockholder of such Subsidiary, in which case the claims of the
Issuer would still be subordinate to any Indebtedness or preferred stock of
such Subsidiary senior in right of payment to that held by the Issuer. In the
event of the liquidation, bankruptcy, reorganization, insolvency, receivership
or similar proceeding or any assignment for the benefit of the creditors of the
Issuer or a marshaling of assets or liabilities of the Issuer, holders of the
new notes may receive ratably less than other such creditors or interest
holders. As of February 28, 1999, the Issuer's Subsidiaries would have had no
long-term Indebtedness outstanding other than their guarantees of the
Indebtedness of the Issuer under the Credit Facility (which was not initially
guaranteed by Centennial de Puerto Rico and its subsidiaries) and the portion
of the Indebtedness borrowed by Centennial de Puerto Rico under the Credit
Facility (which was guaranteed by Centennial Cellular Operating and Centennial
de Puerto Rico's subsidiaries), all of which effectively would have ranked
senior to the new notes.
 
      Upon consummation of the Merger, Centennial Finance Corp., which was
initially an obligor on the old notes, merged with and into Centennial and
Centennial became a joint and several obligor on the notes under the Indenture
pursuant to an Assumption Agreement and Supplemental Indenture to the
Indenture. The Indenture provides that the new notes are senior subordinated
obligations of any co-obligor to the same extent as the obligations are senior
subordinated obligations of the Issuer. As of February 28, 1999, Centennial
(without its subsidiaries) had $933.9 million in aggregate principal amount of
Senior Indebtedness outstanding (representing its guarantee under the Credit
Facility).
 
Optional Redemption by the Co-Obligors
 
      General. The new notes will be subject to redemption at any time on or
after December 15, 2003, at the option of the Co-Obligors, in whole or in part,
on not less than 30 nor more than 60 days' prior notice in amounts of $1,000 or
an integral multiple thereof at the following redemption prices (expressed as
percentages of the principal amount), if redeemed during the 12-month period
beginning December 15 of the years indicated below:

</TABLE>
 
and thereafter at 100% of the principal amount, in each case, together with
accrued and unpaid interest, if any, to the redemption date (subject to the
rights of holders of record on relevant record dates to receive interest due on
an interest payment date).
 
                                       72
<PAGE>
 
      Upon Certain Equity Offerings. In addition, at any time after
consummation of the merger and prior to December 15, 2001, the Co-Obligors, at
their option, may use the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings in a single transaction or a series of
related transactions to redeem up to an aggregate of 35% of the aggregate
principal amount of notes originally issued under the Indenture at a redemption
price equal to 110.750% of the aggregate principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the redemption date (subject to the
rights of holders of record on relevant record dates to receive interest due on
an interest payment date); provided that:
 
     .  at least 65% of the initial aggregate principal amount of Notes
        remains outstanding immediately after the occurrence of such
        redemption,
 
     .  any such redemption with respect to a Strategic Equity Offering may
        not occur in connection with or after the occurrence of a Change of
        Control, and
 
     .  any such net proceeds received by Centennial or any other direct or
        indirect parent of the Issuer are first contributed to the Issuer as
        a capital contribution prior to any such redemption.
 
      In order to effect the foregoing redemption, the Co-Obligors must mail a
notice of redemption no later than 30 days after the closing of the related
Public Equity Offering or Strategic Equity Offering and must consummate such
redemption within 60 days of the closing of the Public Equity Offering or
Strategic Equity Offering.
 
      Upon a Change of Control. In addition, the new notes may be redeemed upon
a Change of Control at any time prior to December 15, 2003, at the option of
the Co-Obligors, in whole and not in part, within 60 days of such Change of
Control at a redemption price equal to:
 
    (1) 100% of the principal amount of the notes, plus
 
    (2) accrued interest to the redemption date (subject to the rights of
        holders of record on relevant record dates to receive interest due
        on an interest payment date), plus
 
    (3) the Applicable Premium, if any.
 
In no event will the redemption price of the new notes be less than 105.375%
(the redemption price for the new notes on December 15, 2003) of the principal
amount of the new notes, plus accrued interest to the applicable redemption
date.
 
      Procedures. Subject to the following, notice of any redemption will be
sent, by first-class mail, at least 30 days and not more than 60 days prior to
the date fixed for redemption to the new holder of each note to be redeemed to
such holder's last address as then shown upon the books of the Registrar. Any
notice which relates to a note to be redeemed in part only must state the
portion of the principal amount to be redeemed and must state that on and after
the date fixed for redemption, upon surrender of such note, a new note or notes
in a principal amount equal to the unredeemed portion thereof will be issued.
On and after the date fixed for redemption, interest will cease to accrue on
the portions of the notes called for redemption.
 
      In the case of a partial redemption, the Trustee shall select the Notes
or portions thereof for redemption as follows:
 
     .  in compliance with the requirements of the principal national
        securities exchange, if any, on which the notes are listed, or
 
     .  if the notes are not so listed, on a pro rata basis, by lot or by
        any other manner as it deems appropriate and fair;
 
provided, that any such redemption pursuant to the provisions relating to a
Public Equity Offering or a Strategic Equity Offering shall be made on a pro
rata basis or on as nearly a pro rata basis as practicable
 
                                       73
<PAGE>
 
(subject to the procedures of DTC or any other depositary). The new notes may
be redeemed in part in multiples of $1,000 only.
 
Sinking Fund
 
      The new notes will not have the benefit of a sinking fund.
 
Security
 
      Pursuant to the Pledge and Escrow Agreement, upon the closing of the
Merger, the Trustee purchased and holds in pledge for the benefit of the
holders of the notes the Pledged Securities in such amount and with such
maturity as will be sufficient upon receipt of scheduled interest and principal
payments of such securities, based on the report of an internationally
recognized firm of independent public accountants or a nationally recognized
investment banking firm, in either case selected by the Co-Obligors, to provide
for payment in full of the first three scheduled interest payments (excluding
Additional Interest) due on the notes (unless already paid). The Pledged
Securities will consist of three groups of Government Securities, one for each
of the first three scheduled interest payments. Each such group will consist of
Government Securities maturing on, or as nearly as possible prior to, the date
of the corresponding scheduled interest payment in an aggregate amount
sufficient upon receipt of scheduled interest and principal payments of such
securities (determined as described in the preceding sentence) to provide for
payment in full of such scheduled interest payment. The Co-Obligors used
approximately $60 million of the net proceeds of the Offering retained in the
Initial Escrow and Pledge Account to acquire the Pledged Securities at the time
of the closing of the Merger. The Pledged Securities were pledged by the Co-
Obligors to the Trustee for the benefit of the holders of notes pursuant to the
Pledge and Escrow Agreement and are held by the Trustee in the Subsequent
Collateral Investments Account (or other accounts). Pursuant to the Pledge and
Escrow Agreement, immediately prior to an Interest Payment Date on the Notes,
the Co-Obligors may either deposit with the Trustee, from funds otherwise
available to the Co-Obligors, cash sufficient to pay the interest scheduled to
be paid on such date, or the Co-Obligors may direct the Trustee to release from
the Subsequent Collateral Investments Account (or other accounts) proceeds
sufficient to pay interest then due. In the event that the Co-Obligors exercise
the former option, the Co-Obligors may thereafter direct the Trustee to release
to the Co-Obligors proceeds or Pledged Securities from the Subsequent
Collateral Investments Account (or other accounts) in like amount. A failure by
the Co-Obligors to pay interest on the notes in a timely manner on or prior to
the first three scheduled interest payments will constitute an immediate Event
of Default under the Indenture, with no grace or cure period.
 
      Interest earned on the Pledged Securities will be held in a cash
collateral account by the Trustee. In the event that collectively the funds
held in the cash collateral account and the Pledged Securities held in the
Subsequent Collateral Investments Account exceed the amount sufficient, based
on the report of an internationally recognized firm of independent public
accountants or a nationally recognized investment banking firm, in either case
selected by the Co-Obligors, to provide for payment in full of the first three
scheduled interest payments (excluding Additional Interest unless then due and
payable) due on the notes (or, in the event an interest payment or payments
have been made, an amount sufficient to provide for payment in full or any
interest payments remaining, up to and including the third scheduled interest
payment) the Trustee will be permitted to release to the Co-Obligors at the Co-
Obligors' request any such excess amount. The notes will be secured by a first
priority security interest in the Pledged Securities in the Subsequent
Collateral Investments Account and the cash collateral account and,
accordingly, the Pledged Securities in the Subsequent Collateral Investments
Account and the cash collateral account will also secure repayment of the
principal amount of the notes to the extent of such security. The Pledge and
Escrow Agreement allows the Co-Obligors to substitute Marketable U.S.
Securities for the Government Securities originally pledged as collateral;
provided, however, that the Marketable U.S. Securities so substituted must have
a value (measured at the date of substitution), in the opinion of a nationally
recognized firm of independent public accountants selected by the Co-Obligors,
at least equal to 125.0% of the amount of all of the first three scheduled
interest payments on the notes that are unpaid (or the pro rata portion of such
interest payments equal to the percentage of such
 
                                       74
<PAGE>
 
interest payments to be secured by such Marketable U.S. Securities) as of the
date such Marketable U.S. Securities are proposed to be substituted as security
for the Co-Obligors's obligations under the Pledge and Escrow Agreement.
 
      Under the Pledge and Escrow Agreement, assuming that the Co-Obligors make
the first three scheduled interest payments on the notes in a timely manner,
all of the Pledged Securities will have been released from the Subsequent
Collateral Investments Account and thereafter the notes will be unsecured.
 
Certain Covenants
 
      Repurchase of Notes at the Option of the Holder Upon a Change of
Control. The Indenture provides that, in the event that a Change of Control has
occurred, each holder will have the right, at such holder's option, pursuant to
an irrevocable and unconditional offer by the Co-Obligors (the "Change of
Control Offer"), to require the Co-Obligors to repurchase all or any part
(equal to $1,000 principal amount or an integral multiple thereof) of such
holder's notes, on a date (the "Change of Control Purchase Date") that is no
later than 45 Business Days after the occurrence of such Change of Control at a
cash price (the "Change of Control Purchase Price") equal to 101% of the
aggregate principal amount thereof, together with any accrued and unpaid
interest to the Change of Control Purchase Date. The Change of Control Offer
shall be made within 30 Business Days following a Change of Control and shall
remain open for 20 Business Days following its commencement (the "Change of
Control Offer Period"). Upon expiration of the Change of Control Offer Period,
the Co-Obligors shall purchase all notes properly tendered in response to the
Change of Control Offer.
 
      On or before the Change of Control Purchase Date, the Co-Obligors will
 
    (1) accept for payment notes or portions thereof properly tendered
        pursuant to the Change of Control Offer,
 
    (2) deposit with the Paying Agent cash sufficient to pay the Change of
        Control Purchase Price (together with accrued and unpaid interest)
        of all notes so tendered, and
 
    (3) deliver to the Trustee notes so accepted together with an Officers'
        Certificate listing the notes or portions thereof being purchased by
        the Co-Obligors.
 
The Paying Agent promptly will deliver to the holders of notes so accepted
payment in an amount equal to the Change of Control Purchase Price (together
with any accrued and unpaid interest), and the Trustee will promptly
authenticate and mail or deliver to such holders a new note equal in principal
amount to any unpurchased portion of the note surrendered. Any notes not so
accepted will be promptly mailed or delivered by the Co-Obligors to the Holder
thereof. The Co-Obligors will announce publicly the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Purchase
Date.
 
      The Change of Control purchase feature of the notes may make more
difficult or discourage a takeover of the Co-Obligors, and, thus, the removal
of incumbent management. The Change of Control purchase feature resulted from
negotiations between the Co-Obligors and the Initial Purchasers and is not the
result of any intention on the part of the Co-Obligors or their management to
discourage the acquisition of the Co-Obligors.
 
      The Credit Facility provides that certain change of control events with
respect to the Co-Obligors would constitute a default thereunder. Any future
credit agreements or other agreements to which any of the Co-Obligors or any of
their Subsidiaries becomes a party may contain similar restrictions and
provisions. In the event a Change of Control were to occur at a time when the
Co-Obligors are prohibited from purchasing Notes, the Co-Obligors could seek
the consent of their lenders to such purchase of notes, or any of such
companies could attempt to refinance the borrowings that contain such
prohibition. If the Co-Obligors did not obtain such consents or repay such
borrowings, the Co-Obligors would not be able to purchase the notes under a
Change of Control Offer. In such case, the Co-Obligors' failure to purchase
tendered notes would constitute an Event of Default under the Indenture.
 
                                       75
<PAGE>
 
      If a Change of Control Offer is made, there can be no assurance that the
Co-Obligors will have available funds sufficient to pay the Change of Control
Purchase Price for all of the notes that might be delivered by holders of the
notes seeking to accept the Change of Control Offer. See "--Ranking."
Centennial is a holding company with no material assets other than the stock of
the Issuer. The failure of the Co-Obligors to make or consummate the Change of
Control Offer or pay the Change of Control Purchase Price when due will give
the Trustee and the holders of the notes the rights described under "Events of
Default."
 
      The term "all or substantially all" as used in the definition of "Change
of Control" has not been interpreted under New York law (which is the governing
law of the Indenture) to represent a specific quantitative test. As a
consequence, in the event the holders of the notes elected to exercise their
rights under the Indenture and the Co-Obligors elected to contest such
election, there could be no assurance as to how a court interpreting New York
law would interpret the phrase.
 
      The provisions of the Indenture do not afford holders of the notes the
right to require the Co-Obligors to repurchase the notes in the event of a
highly leveraged transaction or certain transactions with the Co-Obligors'
management or Affiliates, including a reorganization, restructuring, merger or
similar transaction (including, in certain circumstances, an acquisition of the
Co-Obligors by management or its affiliates) involving the Co-Obligors that may
adversely affect holders of the notes, if such transaction is not a transaction
defined as a Change of Control. A transaction involving the Co-Obligors'
management or Affiliates, or a transaction involving a recapitalization of the
Co-Obligors, will result in a Change of Control if it is the type of
transaction specified by such definition.
 
      Any Change of Control Offer will be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation
14E under the Exchange Act and the rules thereunder and all other applicable
Federal and state securities laws and the Co-Obligors may modify a Change of
Control Offer to the extent necessary to effect such compliance.
 
      Limitation on Incurrence of Additional Indebtedness. The Issuer will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, issue, create, incur, assume, guarantee or otherwise directly or
indirectly become liable for, or otherwise become responsible for, contingently
or otherwise (individually or collectively, to "Incur" or, as appropriate, an
"Incurrence"), any Indebtedness (including any Acquired Indebtedness). Neither
the accrual of interest (including the issuance of "pay in kind" securities or
similar instruments in respect of such accrued interest) pursuant to the terms
of Indebtedness Incurred in compliance with this covenant, nor the accretion of
original issue discount, nor the mere extension of the maturity of any
Indebtedness shall be deemed to be an Incurrence of Indebtedness.
 
      Notwithstanding the foregoing, the Issuer and any Guarantor may Incur
Indebtedness (including Acquired Indebtedness) and any Restricted Subsidiary
may Incur Acquired Indebtedness if the Issuer's Annual Operating Cash Flow
Ratio, after giving effect to the Incurrence of such Indebtedness and the
application of the proceeds therefrom, would have been less than 8.25 to 1.0 at
any time prior to December 31, 2000 and 7.5 to 1.0 thereafter.
 
      In addition, the foregoing limitations will not apply to the Incurrence
of the following:
 
     (1) Indebtedness of the Issuer, any Guarantor or Centennial de Puerto

"Affiliate Transaction") involving in one or a series of related transactions
an aggregate consideration in excess of $5.0 million, unless (a) such Affiliate
Transaction is on terms that are not materially less favorable to the Issuer or

         the holders of the notes in any material respect) or any
         transaction contemplated thereby,
 
     (9) the existence of, or the performance by the Issuer or any of its
         Restricted Subsidiaries of its obligations under the terms of, the
         Recapitalizatioers agreement (including any registration rights
         agreement or purchase agreement related thereto) to which it is a
         party on the Issue Date and any similar agreements which it may
         enter into thereafter; provided, however, that the existence of, or
         the performance by the Issuer or any of its Restricted Subsidiaries
         of obligations under any future amendment to any such existing
         agreement or under any similar agreement entered into after the

         purposes, which payments are not in excess of the tax liabilities
         attributable solely to the Issuer and its Restricted Subsidiaries
         (as a consolidated, combined or unitary group).
 
      Limitation on Issuances of Guarantees. (a) The Issuer will not cause or
permit any Restricted Subsidiary (which is not a Guarantor), directly or
indirectly, to guarantee, assume or in any other manner become liable with
respect to any Indebtedness of the Issuer or any Restricted Subsidiary (other
than under the Credit Facility, except for any Indebtedness under the Credit
Facility constituting Pari Passu Indebtedness or Subordinated Indebtedness)
unless such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a Guarantee of the notes
on the same terms as the guarantee of such Indebtedness except that
 
    (A) such guarantee need not be secured unless required pursuant to "--
        Limitation on Liens,"
 
    (B) if such Indebtedness is by its terms Senior Indebtedness, any such
        assumption, guarantee or other liability of such Restricted
        Subsidiary with respect to such Indebtedness shall be senior to such
        Restricted Subsidiary's Guarantee of the notes to the same extent as
        such Senior Indebtedness is senior to the notes, and
 
                                      83
<PAGE>
 
    (C) if such Indebtedness is by its terms expressly subordinated to the
        notes, any such assumption, guarantee or other liability of such
        Restricted Subsidiary with respect to such Indebtedness shall be
        subordinated to such Restricted Subsidiary's Guarantee of the notes
        at least to the same extent as such Indebtedness is subordinated to
        the notes.
 
      (b) Notwithstanding the foregoing, any Guarantee by a Restricted
Subsidiary of the notes will provide by its terms that it (and all Liens
securing the same) shall be automatically and unconditionally released and
discharged upon
 
    (1) any sale, exchange or transfer, to any Person not an Affiliate of
        the Issuer, of all of the Issuer's Capital Stock in, or all or
        substantially all the assets of, such Restricted Subsidiary, which
        transaction is in compliance with the terms of the Indenture and
        such Restricted Subsidiary is released from all guarantees, if any,
        by it or other Indebtedness of the Issuer or any Restricted
        Subsidiaries, or
 
    (2) the release by the holders of the Indebtedness of the Issuer
        described in clause (a) above or their guarantee by such Restricted
        Subsidiary (including any deemed release upon payment in full of all
        obligations under such Indebtedness), which resulted in the notes
        being guaranteed by such Restricted Subsidiary, at such time as
 
     .  no other Indebtedness of the Issuer has been guaranteed by such
        Restricted Subsidiary or
 
     .  the holders of all such other Indebtedness which is guaranteed by
        such Restricted Subsidiary also release their guarantee by such
        Restricted Subsidiary (including any deemed release upon payment
        in full of all obligations under such Indebtedness).
 
      Limitation on Asset Sales and Sales of Subsidiary Stock. The Indenture
provides that the Issuer will not, and will not permit any of its Restricted
Subsidiaries to, in one or a series of related transactions, convey, sell,
transfer, assign or otherwise dispose of, directly or indirectly, any of its
property, businesses or assets, including by merger or consolidation or sale
and leaseback transaction, and including any sale or other transfer or issuance
of any Capital Stock of any Restricted Subsidiary of the Issuer, whether by the
Issuer or a Restricted Subsidiary (an "Asset Sale"), unless
 
    (1)
 
     .  within one year after the date of such Asset Sale, an amount equal
        to the Net Cash Proceeds therefrom (the "Asset Sale Offer Amount")
        are applied to the optional redemption of the notes in accordance
        with the terms of the Indenture and other Indebtedness of the
        Issuer ranking on a parity with the notes from time to time
        outstanding with similar provisions requiring the Issuer to make
        an offer to purchase or to redeem such Indebtedness with the
        proceeds from asset sales, pro rata in proportion to the
        respective principal amounts (or accreted values in the case of
        Indebtedness issued with an original issue discount) of the notes
        and such other Indebtedness then outstanding or to the repurchase
        of the notes and such other Indebtedness pursuant to an
        irrevocable, unconditional offer (the "Asset Sale Offer") to
        repurchase such Indebtedness at a purchase price (the "Asset Sale
        Offer Price") of 100% of the principal amount thereof in the case
        of the notes or 100% of the principal amount (or accreted value in
        the case of Indebtedness issued with an original issue discount)
        of such Indebtedness, plus, in each case, accrued interest to the
        date of payment, made within one year of such Asset Sale, or
 
     .  within one year of such Asset Sale, the Asset Sale Offer Amount is
        (i) invested (or committed, pursuant to a binding commitment
        subject only to reasonable, customary closing conditions, to be
        invested, and in fact is so invested, within an additional 90
        days) in tangible assets and property (other than notes,
        obligations or securities), which in the good faith reasonable
        judgment of the Issuer are of a type used in a Related Business,
        or Capital Stock
 
                                       84
<PAGE>
 
        of a Person (which, if such Person becomes a Subsidiary of the
        Issuer by virtue of such Asset Sale, shall initially be designated
        a Restricted Subsidiary) all or substantially all of whose assets
        and property (in the good faith reasonable judgment of the Issuer)
        are of a type used in a Related Business (provided that, with
        respect to such Capital Stock, all of the requirements of the last
        proviso of clause (5) of the following paragraph shall have been
        satisfied) or (ii) used to permanently retire Senior Indebtedness
        of the Issuer or any Guarantor or Indebtedness of any Restricted
        Subsidiary (which is not a Guarantor),
 
    (2) with respect to any transaction or related series of transactions of
        securities, property or assets with an aggregate fair market value
        in excess of $2,500,000, at least 75% of the value of consideration
        for the assets disposed of in such Asset Sale, excluding
 
     .  Senior Indebtedness under a bank credit facility (and any
        Refinancing Indebtedness issued to refinance any such
        Indebtedness) or any Indebtedness of a Restricted Subsidiary in
        each case that is assumed by a transferee which assumption
        permanently reduces the amount of Indebtedness outstanding on the
        Issue Date and permitted to have been Incurred pursuant to the
        covenant "--Limitation on Incurrence of Additional Indebtedness"
        (including that in the case of a revolver or similar arrangement
        that makes credit available, such commitment is permanently
        reduced by such amount),
 
     .  Purchase Money Indebtedness secured exclusively by the assets
        subject to such Asset Sale which is assumed by a transferee, and
 
     .  marketable securities that are promptly converted into cash or
        Cash Equivalents) consists of cash or Cash Equivalents, provided
        that any cash or Cash Equivalents received within 12 months
        following any such Asset Sale upon conversion of any property or
        assets (other than in the form of cash or Cash Equivalents)
        received in consideration of such Asset Sale shall be applied
        promptly in the manner required of Net Cash Proceeds of any such
        Asset Sale as set forth above (provided further that the Issuer
        and its Restricted Subsidiaries shall not be required to receive
        any cash in connection with the transfer or contribution of assets
        to a joint venture), and
 
    (3) the Board of Directors of the Issuer determines in good faith that
        the Issuer or such Restricted Subsidiary, as applicable, would
        receive fair market value in consideration of such Asset Sale. The
        Indenture provides that an Asset Sale Offer may be deferred until
        the accumulated Net Cash Proceeds from Asset Sales not applied to
        the uses set forth in
 
     .  above exceeds $15,000,000 and that each Asset Sale Offer shall
        remain open for 20 Business Days following its commencement and no
        longer, except as otherwise required by applicable law (the "Asset
        Sale Offer Period"). Upon expiration of the Asset Sale Offer
        Period, the Issuer shall apply the Asset Sale Offer Amount, plus
        an amount equal to accrued interest to the purchase of all
        Indebtedness properly tendered (on a pro rata basis as described
        above if the Asset Sale Offer Amount is insufficient to purchase
        all Indebtedness so tendered) at the Asset Sale Offer Price
        (together with accrued interest).
 
      Notwithstanding the foregoing provisions of the prior paragraph:
 
    (1) the Issuer and its Restricted Subsidiaries may, in the ordinary
        course of business, convey, sell, lease, transfer, assign or
        otherwise dispose of assets acquired and held for resale in the
        ordinary course of business,
 
    (2) the Issuer and its Restricted Subsidiaries may convey, sell, lease,
        transfer, assign or otherwise dispose of assets pursuant to and in
        accordance with the "--Limitation on Mergers, Sales or
        Consolidations" covenant,
 
                                      85
<PAGE>
 
    (3) the Issuer and its Restricted Subsidiaries may sell or dispose of
        damaged, worn out or other obsolete property in the ordinary course
        of business so long as such property is no longer necessary for the
        proper conduct of the business of the Issuer or such Restricted
        Subsidiary, as applicable,
 
    (4) the Issuer and its Restricted Subsidiaries may convey, sell, lease,
        transfer, assign or otherwise dispose of assets to the Issuer or any
        of its Restricted Subsidiaries in accordance with the terms of the
        Indenture, and
 
    (5) the Issuer and its Restricted Subsidiaries may, in the ordinary
        course of business (or, if otherwise than in the ordinary course of
        business, in the case of exchanges in excess of $15 million upon
        receipt of a favorable written opinion by an independent financial
        advisor of national reputation as to the fairness from a financial
        point of view to the Issuer or such Restricted Subsidiary of the
        proposed transaction), exchange all or a portion of its property,
        businesses or assets for property, businesses or assets which, or
        Capital Stock of a Person all or substantially all of whose assets,
        are of a type used in the business of the Issuer on the date of the
        Indenture or a Related Business (provided that such Person shall
        initially be designated a Restricted Subsidiary if such Person
        becomes a Subsidiary of the Issuer by virtue of such Asset Sale), or
        a combination of any such property, businesses or assets, or Capital
        Stock of such a Person and cash or Cash Equivalents, provided that
 
     .  a majority of the Disinterested Directors of the Board of
        Directors of the Issuer shall have approved a resolution of the
        Board of Directors that such exchange is fair to the Issuer or
        such Restricted Subsidiary, as the case may be,
 
     .  any cash or Cash Equivalents received pursuant to any such
        exchange shall be applied in the manner applicable to Net Cash
        Proceeds from an Asset Sale as set forth pursuant to the
        provisions of the immediately preceding paragraph of this
        covenant, and
 
     .  any Capital Stock of a Person received in an Asset Sale pursuant
        to this clause (5) shall be owned directly by the Issuer or a
        Restricted Subsidiary and, when combined with the Capital Stock of
        such Person already owned by the Issuer and its Restricted
        Subsidiaries, shall constitute a majority of the voting power and
        Capital Stock of such Person.
 
      Restricted Payments that are made in compliance with "--Limitation on
Restricted Payments" shall not be deemed to be Asset Sales.
 
      Any Asset Sale Offer shall be made in compliance with all applicable
laws, rules, and regulations, including, if applicable, Regulation 14E of the
Exchange Act and the rules and regulations thereunder and all other applicable
Federal and state securities laws.
 
      Limitation on Liens. The Issuer will not, and will not cause or permit
any Restricted Subsidiary to, directly or indirectly, create, incur or affirm
any Lien of any kind securing any Pari Passu Indebtedness or Subordinated
Indebtedness (including any assumption, guarantee or other liability with
respect thereto by any Restricted Subsidiary) upon any property or assets
(including any intercompany notes) of the Issuer or any Restricted Subsidiary
owned on the date of the Indenture or acquired after the date of the Indenture,
or any income or profits therefrom, unless the Notes are directly secured
equally and ratably with (or, in the case of Subordinated Indebtedness, prior
or senior thereto, with the same relative priority as the Notes shall have with
respect to such Subordinated Indebtedness) the obligation or liability secured
by such Lien except for Liens
 
    (A) securing any Indebtedness which became Indebtedness pursuant to a
        transaction permitted under "--Limitation on Merger, Sale or
        Consolidation" or securing Acquired Indebtedness which was created
        prior to (and not created in connection with, or in contemplation
        of) the incurrence of such Pari Passu Indebtedness or Subordinated
        Indebtedness (including any assumption, guarantee
 
                                       86
<PAGE>
 
       or other liability with respect thereto by any Restricted Subsidiary)
       and which Indebtedness is permitted under the provisions of "--
       Limitation on Incurrence of Additional Indebtedness," or
 
    (B) securing any Indebtedness incurred in connection with any
        refinancing, renewal, substitutions or replacements of any such
        Indebtedness described in clause (A), so long as the aggregate
        principal amount of Indebtedness represented thereby (or if such
        Indebtedness provides for an amount less than the principal amount
        thereof to be due and payable upon a declaration of acceleration of
        the maturity thereof, the original issue price of such Indebtedness
        plus any accreted value attributable thereto since the original
        issuance of such Indebtedness) is not increased by such refinancing
        by an amount greater than the lesser of
 
     .  the stated amount of any premium or other payment required to be
        paid in connection with such a refinancing pursuant to the terms
        of the Indebtedness being refinanced, or
 
     .  the amount of premium or other payment actually paid at such time
        to refinance the Indebtedness, plus, in either case, the amount of
        expenses of the Issuer incurred in connection with such
        refinancing; provided, however, that in the case of clauses (A)
        and (B), any such Lien only extends to the assets that were
        subject to such Lien securing such Indebtedness prior to the
        related acquisition by the Issuer or its Restricted Subsidiaries.
 
      Notwithstanding the foregoing, any Lien securing the notes granted
pursuant to this covenant shall be automatically and unconditionally released
and discharged upon the release by the holders of the Pari Passu Indebtedness
or Subordinated Indebtedness described above of their Lien on the property or
assets of the Issuer or any Restricted Subsidiary (including any deemed
release upon payment in full of all obligations under such Indebtedness), at
such time as the holders of all such Pari Passu Indebtedness or Subordinated
Indebtedness also release their Lien on the property or assets of the Issuer
or such Restricted Subsidiary, or upon any sale, exchange or transfer to any
Person not an Affiliate of the Issuer of the property or assets secured by
such Lien, or of all of the Capital Stock held by the Issuer or any Restricted
Subsidiary in, or all or substantially all the assets of, any Restricted
Subsidiary creating such Lien.
 
      Limitation on Merger, Sale or Consolidation. The Issuer will not
consolidate with or merge with or into another Person, or sell, lease, convey,
transfer or otherwise dispose of all or substantially all of its properties
and assets (computed on a consolidated basis), whether in a single transaction
or a series of related transactions, to another Person or group of affiliated
Persons, and the Issuer will not permit any Restricted Subsidiary to enter
into any such transaction or series of transactions which would result in a
sale, lease, conveyance, transfer or other disposition of all or substantially
all of the properties and assets of the Issuer on a consolidated basis, unless
 
    (1) either (a) the Issuer is the continuing entity or (b) the resulting,
        surviving or transferee entity is an entity organized under the laws
        of the United States, any state thereof or the District of Columbia
        and expressly assumes by supplemental indenture all of the
        obligations of the Issuer in connection with the Notes, the
        Indenture and the Registration Rights Agreement, as the case may be,
        and the Notes, the Indenture and the Registration Rights Agreement
        will remain in full force and effect as so supplemented (and any
        Guarantee shall be confirmed as applied to the surviving entity's
        obligations),
 
    (2) no Default or Event of Default shall exist or shall occur
        immediately after giving effect on a pro forma basis (and treating
        any Indebtedness not previously an obligation of the Issuer or any
        of its Restricted Subsidiaries which becomes the obligation of the
        Issuer or any of its Restricted Subsidiaries as a result of such
        transaction as having been incurred at the time of such transaction)
        to such transaction,
 
    (3) immediately before and immediately after giving effect to such
        transaction on a pro forma basis (on the assumption that the
        transaction occurred on the first day of the four-quarter period for
        which financial statements are available ending immediately prior to
        the consummation of such
 
                                      87
<PAGE>
 
       transaction with the appropriate adjustments with respect to the
       transaction being included in such pro forma calculation), either the
       Issuer or resulting surviving or transferee entity would immediately
       thereafter be permitted to incur at least $1.00 of additional
       Indebtedness pursuant to the Annual Operating Cash Flow Ratio
       provision set forth in the second paragraph of the "--Limitation on
       Incurrence of Additional Indebtedness" covenant or such Annual
       Operating Cash Flow Ratio would be lower than such ratio immediately
       prior to such transaction,
 
    (4) at the time of the transaction any co-obligor, unless it is the
        other party to the transaction described above, will have by
        supplemental indenture confirmed that it remains a co-obligor under
        the Indenture and the Notes,
 
    (5) at the time of the transaction each Guarantor, if any, unless it is
        the other party to the transaction described above, will have by
        supplemental indenture confirmed that its Guarantee shall apply to
        such Person's obligations under the Indenture and the Notes, and
 
    (6) at the time of the transaction the Issuer or the resulting surviving
        or transferee entity will have delivered, or caused to be delivered,
        to the Trustee, in form and substance reasonably satisfactory to the
        Trustee, an officers' certificate and an opinion of counsel, each to
        the effect that such consolidation, merger, transfer, sale,
        assignment, conveyance, transfer, lease or other transaction and the
        supplemental indenture in respect thereof comply with the Indenture
        and that all conditions precedent therein provided for relating to
        such transaction have been complied with.
 
      Notwithstanding the foregoing, any Restricted Subsidiary may merge with
and into any other Restricted Subsidiary or the Issuer.

      Centennial will not, in a single transaction or through a series of
related transactions, consolidate with or merge with or into any other Person
(other than (i) the Issuer or any Guarantor, (ii) CCW Acquisition Corp. in
connection with the Merger or (iii) Finance Corp. upon consummation of the
Merger) or sell, assign, convey, transfer, lease or otherwise dispose of all
or substantially all of its properties and assets to any Person or group of

    (1) either (a) Centennial will be the continuing corporation or (b) the
        Person (if other than Centennial) formed by such consolidation or
        into which Centennial is merged or the Person which acquires by

        substantially all of the properties and assets of Centennial on a
        Consolidated basis will be a corporation duly organized and validly
        existing under the laws of the United States of America, any state

        and such Note, Indenture and Registration Rights Agreement will
        remain in full force and effect,
 
    (2) immediately before and immediately after giving effect to such
        transaction on a pro forma basis, no Default or Event of Default
        will have occurred and be continuing, and
 
    (3) at the time of the transaction Centennial or the surviving entity
        will have delivered, or caused to be delivered, to the Trustee, in
        form and substance reasonably satisfactory to the Trustee, an
        officers' certificate and an opinion of counsel, each to the effect

        conveyance, lease or other transaction and the supplemental
        indenture in respect thereof comply with the Indenture and that all
        conditions precedent therein provided for relating to such

      In the event that Centennial shall merge or consolidate with or into the
Issuer, the provisions of the first paragraph of this Section are also required
to be satisfied.
 
      Upon any consolidation or merger or any transfer (other than a lease) of
all or substantially all of the assets of the Issuer or Centennial, as the case
may be in accordance with the foregoing, the successor corporation formed by
such consolidation or into which the Issuer or Centennial, as the case may be,
is merged or to which such transfer is made, shall succeed to, and be
substituted for, and may exercise every right and power of, the Issuer or
Centennial, as the case may be, under the Indenture with the same effect as if
such successor entity had been named therein as the Issuer or Centennial, as
the case may be, and the Issuer or Centennial, as the case may be (except in
connection with a transfer that results in the transfer of assets constituting
or accounting for less than 95% of the consolidated assets (as of the last
balance sheet available), revenues, or Annual Operating Cash Flow of the Issuer
or Centennial, as the case may be (as of the last twelve month period for which
financial statements are available), shall be released from the obligations
under the notes and the Indenture.
 
      Limitation on Lines of Business. Neither the Issuer nor any of its
Restricted Subsidiaries shall directly or indirectly engage in any line or
lines of business activity other than that which, in the reasonable, good faith
judgment of the Board of Directors of the Issuer, is a Related Business.
 
      Limitation on Activities Prior to the Merger. Prior to consummation of
the Merger, the Co-Obligors may not, and must cause their Subsidiaries not to,
incur any Indebtedness or engage in any activities other than in connection
with the Merger and the Credit Facility.
 
      Transfer of Stock to the Issuer. Immediately following consummation of
the Merger, Centennial shall cause the Capital Stock of all of its existing
Subsidiaries and Minority Cellular Investment Interests to be contributed to
the Issuer and Centennial shall immediately thereafter have no material assets
other than its Investment in the Capital Stock of the Issuer.
 
      Limitation on Senior Subordinated Indebtedness. Each Issuer will not, and
will not permit or cause any Guarantor to, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise in any manner become directly or
indirectly liable for or with respect to or otherwise permit to exist any
Indebtedness that is subordinate in right of payment to any Indebtedness of
such Co-Obligors or such Guarantor, as the case may be, unless such
Indebtedness is also pari passu with the Notes or the Guarantee of such
Guarantor or subordinated in right of payment to the notes or such Guarantee at
least to the same extent as the notes or such Guarantee are subordinated in
right of payment to Senior Indebtedness or Senior Indebtedness of such
Guarantor, as the case may be, as set forth in the Indenture.
 
      Limitation on Unrestricted Subsidiaries. The Indenture provides that the
Issuer may designate any Subsidiary (other than a Guarantor) as an
"Unrestricted Subsidiary" under the Indenture (a "Designation") only if:
 
    (a) no Default shall have occurred and be continuing at the time of or
        after giving effect to such Designation,
 
    (b) the Issuer would be permitted to make an Investment at the time of
        Designation (assuming the effectiveness of such Designation)
        pursuant to "--Limitation on Restricted Payments" above in an amount
        (the "Designation Amount") equal to the greater of (1) the net book
        value of the Issuer's interest in such Subsidiary calculated in
        accordance with GAAP or (2) the fair market value of the Issuer's
        interest in such Subsidiary as determined in good faith by the
        Issuer's board of directors,
 
    (c) such Unrestricted Subsidiary does not own any Capital Stock in any
        Restricted Subsidiary of the Issuer which is not simultaneously
        being designated an Unrestricted Subsidiary,
 
 
                                       89
<PAGE>
 
    (d) such Unrestricted Subsidiary is not liable, directly or indirectly,
        with respect to any Indebtedness other than Unrestricted Subsidiary
        Indebtedness, provided that an Unrestricted Subsidiary may provide a
        Guarantee for the notes, and
 
    (e) such Unrestricted Subsidiary is not a party to any agreement,
        contract, arrangement or understanding at such time with the Issuer
        or any Restricted Subsidiary unless the terms of any such agreement,
        contract, arrangement or understanding are no less favorable to the
        Issuer or such Restricted Subsidiary than those that might be
        obtained at the time from Persons who are not Affiliates of the
        Issuer or, in the event such condition is not satisfied, the value
        of such agreement, contract, arrangement or understanding to such
        Unrestricted Subsidiary shall be deemed a Restricted Payment.
 
      In the event of any such Designation, the Issuer shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
"--Limitation on Restricted Payments" for all purposes of the Indenture in the
Designation Amount.
 
      The Indenture will also provide that the Issuer shall not and shall not
cause or permit any Restricted Subsidiary to at any time
 
     .  provide credit support for (provided that operational contracts in
        the ordinary course of business shall not be deemed credit support),
        or subject any of its property or assets (other than the Capital
        Stock of any Unrestricted Subsidiary) to the satisfaction of, any
        Indebtedness of any Unrestricted Subsidiary (including any
        undertaking, agreement or instrument constituting such Indebtedness)
        (other than Permitted Investments in Unrestricted Subsidiaries), or
 
     .  be directly or indirectly liable for any Indebtedness of any
        Unrestricted Subsidiary.
 
      For purposes of the foregoing, the Designation of a Subsidiary of the
Issuer as an Unrestricted Subsidiary shall be deemed to be the Designation of
all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries.
 
      The Issuer may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:
 
    (a) no Default shall have occurred and be continuing at the time of and
        after giving effect to such Revocation,
 
    (b) all Liens and Indebtedness of such Unrestricted Subsidiary
        outstanding immediately following such Revocation would, if incurred
        at such time, have been permitted to be incurred for all purposes of
        the Indenture, and
 
    (c) unless such redesignated Subsidiary shall not have any Indebtedness
        outstanding (other than Indebtedness that would be Permitted
        Indebtedness), immediately after giving effect to such proposed
        Revocation, and after giving pro forma effect to the incurrence of
        any such Indebtedness of such redesignated Subsidiary as if such
        Indebtedness was incurred on the date of the Revocation, the Issuer
        could incur $1.00 of additional Indebtedness (other than Permitted
        Indebtedness) pursuant to the covenant described under "--Limitation
        on Incurrence of Additional Indebtedness."
 
      All Designations and Revocations must be evidenced by a resolution of the
board of directors of the Issuer delivered to the Trustee certifying compliance
with the foregoing provisions.
 
      Provision of Financial Statements. Whether or not the Issuer is subject
to Section 13(a) or 15(d) of the Exchange Act, so long as any notes are
outstanding, the Issuer will, to the extent permitted under the Exchange Act,
file with the Commission the annual reports, quarterly reports and other
documents which the
 
                                       90
<PAGE>
 
Issuer would have been required to file with the SEC pursuant to Section 13(a)
or 15(d) if it were so subject, such documents to be filed with the SEC on or
prior to the date (the "Required Filing Date") by which the Issuer would have
been required so to file such documents if it were so subject. The Issuer will
also in any event
 
     . within 15 days of each Required Filing Date (whether or not prior to
       the 120th calendar day following the Merger Date) (i) transmit by
       mail to all holders, as their names and addresses appear in the
       security register, without cost to such holders and (ii) file with
       the Trustee copies of the annual reports, quarterly reports and other
       documents which the Issuer would have been required to file with the
       SEC pursuant to Section 13(a) or 15(d) of the Exchange Act if the
       Issuer were subject to either of such Sections, and
 
     . if filing such documents by the Issuer with the SEC is not permitted
       under the Exchange Act, promptly upon written request and payment of
       the reasonable cost of duplication and delivery, supply copies of
       such documents to any prospective purchaser of notes at the Issuer's
       cost.
 
     The Indenture also provides that, so long as any of the notes remain
outstanding, the Issuer will make available to any prospective purchaser of
notes or beneficial owner of notes in connection with any sale thereof the
information required by Rule 144A(d)(4) under the Securities Act, until such
time as the Issuer has either exchanged the notes for securities identical in
all material respects which have been registered under the Securities Act or
until such time as the holders thereof have disposed of such notes pursuant to
an effective registration statement under the Securities Act. The Issuer will
be deemed to have satisfied the requirements set forth above if (a) Centennial
prepares, files, mails and supplies reports and other documents prepared on a
consolidated basis of the types required above, in each case within the
applicable time periods, (b) the Issuer is not required to file such reports
and other documents separately under the applicable rules and regulations of
the SEC (after giving effect to any exemptive relief) because of the filings
made by Centennial, (c) Centennial does not own assets in excess of $10 million
other than the Capital Stock of the Issuer, and (d) Centennial does not have
outstanding Indebtedness in excess of $10 million (other than indebtedness
under the Mezzanine Financing and Indebtedness as to which the Issuer is also
liable).
 
     Amendments to Mezzanine Financing. The Indenture provides that the
Mezzanine Financing shall be in substantially the form attached to the
Indenture and Centennial shall not amend the terms of the Mezzanine Financing
in a manner adverse to the Holders.
 
     Additional Covenants. The Indenture also contains covenants with respect
to the following matters:
 
     . payment of principal, premium and interest,
 
     . maintenance of an office or agency in The City of New York,
 
     . arrangements regarding the handling of money held in trust,
 
     . maintenance of corporate existence,
 
     . payment of taxes and other claims,
 
     . maintenance of properties, and
 
     . maintenance of insurance.
 
Events of Default and Remedies
 
     The Indenture defines an Event of Default as
 
    (1) the failure by Finance Corp. or the Issuer to pay any installment of
        interest on the notes as and when the same becomes due and payable
        and, with respect to any installment of interest after the
 
                                       91

        otherwise, including, without limitation, payment of the Change of
        Control Purchase Price or the Asset Sale Offer Price (whether or not
        prohibited by the subordination provisions of the Indenture),
 
    (3) the failure by Finance Corp. or the Issuer to observe or perform any

        Subsidiary under any applicable federal or state law, or appointing
        a custodian, receiver, liquidator, assignee, trustee, sequestrator
        (or other similar official) of Centennial, the Issuer or any
        Significant Restricted Subsidiary or of any substantial part of
        their respective properties, or ordering the winding up or
        liquidation of their affairs, and any such decree or order for
        relief shall continue to be in effect, or any such other decree or
        order shall be unstayed and in effect, for a period of 60
        consecutive days,
 
    (5) (a) Centennial, the Issuer, or any Significant Restricted Subsidiary

        Restricted Subsidiary or of any substantial part of their respective
        properties, (II) makes an assignment for the benefit of creditors or

        contemplated by the Indenture and any such Guarantee, or Finance
        Corp. shall for any reason cease to be, or shall for any reason be

    (7) one or more defaults in any Indebtedness for money borrowed by
        Finance Corp., the Issuer or any of their Restricted Subsidiaries
        (or the payment of which is guaranteed by Finance Corp., the Issuer
        or any of their Restricted Subsidiaries), whether such Indebtedness
        or guarantee now exists or is created after the Issue Date, which
        default results from the failure to pay Indebtedness at its final
        maturity date or results in the acceleration of such Indebtedness
        prior to its express maturity
 
                                      92
<PAGE>
 
       and, in each case, the principal amount of any such Indebtedness,
       together with the principal amount of any other such Indebtedness
       which was not paid at its final maturity date or the maturity of
       which has been so accelerated, aggregates $20,000,000 or more, and
 
    (8) final unsatisfied judgments, orders or decrees (not subject to
        appeal) of any court or regulatory or administrative agency
        aggregating in excess of $20,000,000 (exclusive of any portion of
        any such payment covered by insurance, if and to the extent the
        insurer has acknowledged in writing its liability therefor), at any
        one time rendered against Finance Corp., the Issuer or any of its
        Restricted Subsidiaries and not stayed, bonded or discharged within
        60 days. The Indenture provides that, if a Default occurs and is
        continuing, the Trustee must, within 90 days after the occurrence of
        such Default, give to the Holders notice of such Default.
 
      If an Event of Default occurs and is continuing (other than an Event of
Default specified in clauses (iv) and (v) above relating to Centennial, the
Issuer or any Significant Restricted Subsidiary), then in every such case,
unless the principal of all of the Notes shall have already become due and
payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, by notice in writing to the
Issuer (and to the Trustee if given by Holders) (an "Acceleration Notice"), may
declare all principal of the Notes (or the Change in Control Purchase Price if
the Event of Default includes failure to pay the Change in Control Purchase
Price) (or the Special Redemption Price in connection with any Special
Mandatory Redemption if the Event of Default relates to failure to make payment
in connection with the Special Mandatory Redemption), determined as set forth
below, including in each case accrued interest thereon to be due and payable
immediately; provided that so long as the Credit Facility shall be in full
force and effect, if an Event of Default shall have occurred and be continuing
(other than as specified in clauses (4) or (5) with respect to Centennial, the
Issuer or any Significant Restricted Subsidiary), any such acceleration shall
not be effective until the earlier to occur of (x) five business days following
delivery of a written notice of such acceleration of the Notes to the agent
under the Credit Facility and (y) the acceleration of any Indebtedness under
the Credit Facility. If an Event of Default specified in clauses (4) and (5)
above relating to Centennial, the Issuer or any Restricted Subsidiary occurs,
all principal and accrued interest thereon will be immediately due and payable
on all outstanding Notes without any declaration or other act on the part of
Trustee or the Holders. The Holders of a majority in aggregate principal amount
of notes generally are authorized to rescind such acceleration if all existing
Events of Default, other than the non-payment of the principal of, premium, if
any, and interest on the Notes which have become due solely by such
acceleration, have been cured or waived.
 
      The Holders of a majority in aggregate principal amount of the notes at
the time outstanding may waive on behalf of all the Holders any Default, except
a Default in the payment of principal of or interest on any note not yet cured,
or a Default with respect to any covenant or provision which cannot be modified
or amended without the consent of the Holder of each outstanding note affected.
Subject to the provisions of the Indenture relating to the duties of the
Trustee, the Trustee will be under no obligation to exercise any of its rights
or powers under the Indenture at the request, order or direction of any of the
Holders, unless such Holders have offered to the Trustee reasonable security or
indemnity. Subject to all provisions of the Indenture and applicable law, the
Holders of a majority in aggregate principal amount of the Notes at the time
outstanding will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee.
 
      No holder of any of the notes has any right to institute any proceedings
with respect to the Indenture or any remedy thereunder, unless
 
     .  the holders of at least 25% in aggregate principal amount of the
        outstanding Notes have made written request, and offered reasonable
        indemnity, to the Trustee to institute such proceeding as Trustee
        under the notes and the Indenture, and
 
 
                                       93
<PAGE>
 
     .  the Trustee has failed to institute such proceeding within 15 days
        after receipt of such notice and the Trustee, within such 15-day
        period, has not received directions inconsistent with such written
        request by holders of a majority in aggregate principal amount of
        the outstanding notes.
 
      Such limitations do not, however, apply to a suit instituted by a holder
of a Note for the enforcement of the payment of the principal of, premium, if
any, or interest on such note on or after the respective due dates expressed in
such note.
 
      The Co-Obligors are required to notify the Trustee within five business
days of the occurrence of any Default. The Co-Obligors are required to deliver
to the Trustee, not more than 120 days after the end of each fiscal year, a
written statement as to compliance with the Indenture, including whether or not
any Default has occurred.
 
      The Trust Indenture Act contains limitations on the rights of the
Trustee, should it become a creditor of Centennial, the Issuer or any
Guarantor, if any, to obtain payment of claims in certain cases or to realize
on certain property received by it in respect of any such claims, as security
or otherwise. The Trustee is permitted to engage in other transactions,
provided that if it acquires any conflicting interest it must eliminate such
conflict upon the occurrence of an Event of Default or else resign.
 
Legal Defeasance and Covenant Defeasance
 
      The Indenture provides that the Issuer may, at its option and at any
time, elect to have the obligations of Centennial, the Issuer, any Guarantor
and any other obligor upon the Notes discharged with respect to the outstanding
notes ("Legal Defeasance"). Such Legal Defeasance means that Centennial, the
Issuer, any such Guarantor and any other obligor under the Indenture shall be
deemed to have paid and discharged the entire indebtedness represented, and the
Indenture shall cease to be of further effect as to all outstanding notes,
except as to
 
    (1) rights of Holders to receive payments in respect of the principal
        of, premium, if any, and interest on such notes when such payments
        are due from the trust funds,
 
    (2) the Co-Obligors' obligations with respect to such notes concerning
        issuing temporary notes, registration of notes, mutilated,
        destroyed, lost or stolen notes, and the maintenance of an office or
        agency for payment and money for security payments held in trust,
 
    (3) the rights, powers, trust, duties, and immunities of the Trustee,
        and the Issuer's obligations in connection therewith, and
 
    (4) the Legal Defeasance provisions of the Indenture.
 
      In addition, the Issuer may, at its option and at any time, elect to have
the obligations of Centennial, the Issuer and any Guarantor released with
respect to certain covenants that are described in the Indenture ("Covenant
Defeasance") and thereafter any omission to comply with such obligations shall
not constitute a Default or Event of Default with respect to the notes. In the
event Covenant Defeasance occurs, certain events (not including events
described in clauses (1), (2), (4) (with respect to the Co-Obligors) and (5)
(with respect to the Co-Obligors) described under "--Events of Default") will
no longer constitute an Event of Default with respect to the notes.
 
      In order to exercise either Legal Defeasance or Covenant Defeasance,
 
    (1) the Issuer must irrevocably deposit with the Trustee, in trust, for
        the benefit of the Holders, U.S. Legal Tender, non-callable
        government securities or a combination thereof, in such amounts as
        will be sufficient, in the opinion of a nationally recognized firm
        of independent public accountants, to pay the principal of, premium,
        if any, and interest on such notes on the stated date
 
                                       94
<PAGE>
 
       for payment thereof or on any redemption date of such principal or
       installment of principal of, premium, if any, or interest on such
       notes, and the holders of notes must have a valid, perfected,
       exclusive security interest in such trust,
 
    (2) in the case of Legal Defeasance, the Issuer shall have delivered to
        the Trustee an opinion of counsel in the United States reasonably
        acceptable to the Trustee confirming that
 
     .  the Issuer has received from, or there has been published by the
        Internal Revenue Service, a ruling, or
 
     .  since the date of the Indenture, there has been a change in the
        applicable Federal income tax law, in each case to the effect
        that, and based thereon such opinion of counsel shall confirm
        that, the holders of such notes will not recognize income, gain or
        loss for Federal income tax purposes as a result of such Legal
        Defeasance, and will be subject to Federal income tax in the same
        amount, in the same manner and at the same times as would have
        been the case if such Legal Defeasance had not occurred,
 
    (3) in the case of Covenant Defeasance, the Issuer shall have delivered
        to the Trustee an opinion of counsel in the United States reasonably
        acceptable to such Trustee confirming that the holders of such notes
        will not recognize income, gain or loss for Federal income tax
        purposes as a result of such Covenant Defeasance and will be subject

        on the date of such deposit or insofar as Events of Default from
        bankruptcy or insolvency events are concerned, at any time in the
        period ending on the 91 date of deposit (other than a Default which
        results from the borrowing of amounts to finance the defeasance and
        which borrowing does not result in a breach or violation of, or
        constitute a default under, any other material agreement or
        instrument to which Centennial, the Issuer or any Restricted
        Subsidiary is a party or to which it is bound) (it being understood
        that such condition will not be satisfied until the expiration of
        such 91-day period),

        in the United States reasonably acceptable to the Trustee to the
        effect that (assuming that no holder of any notes would be
        considered an insider of the Issuer under any applicable bankruptcy
        or insolvency law) after the 91st day following the deposit, the
        trust funds will not be subject to the effect of any applicable
        bankruptcy, insolvency, reorganization or similar laws affecting
        creditors rights generally,
 
    (6) such defeasance or covenant defeasance shall not cause the Trustee
        for the notes to have a conflicting interest for purposes of the
        Trust Indenture Act with respect to any securities of the Issuer or
        any Guarantor,
 
    (7) such Legal Defeasance or Covenant Defeasance shall not result in a
        breach or violation of, or constitute a default under the Indenture
        or any other material agreement or instrument to which Centennial,
        the Issuer or any of their Subsidiaries is a party or by which
        Centennial, the Issuer or any of their Subsidiaries is bound,
 
    (8) the Issuer shall have delivered to the Trustee an officers'
        certificate stating that the deposit was not made by the Issuer with
        the intent of preferring the Holders of such notes over any other
        creditors of the Issuer or with the intent of defeating, hindering,
        delaying or defrauding any other creditors of the Issuer or others,
        and
 
    (9) the Issuer shall have delivered to the Trustee an officers'
        certificate and opinion of counsel each stating that all conditions
        precedent provided for or relating to the Legal Defeasance or the
        Covenant Defeasance have been complied with. References in this
        section to "Centennial" refer to Finance Corp. before the Merger and

        the entire indebtedness on the Notes not theretofore delivered to
        the Trustee for cancellation, including principal of, premium, if

        certificate and an opinion of independent counsel each stating that
        (i) all conditions precedent under the Indenture relating to the
        satisfaction and discharge of such Indenture have been complied with
        and (ii) such satisfaction and discharge will not result in a breach
        or violation of, or constitute a default under, the Indenture or any
        other material agreement or instrument to which Centennial, the
        Issuer, any Guarantor or any Subsidiary is a party or by which
        Centennial, the Issuer, any Guarantor or any Subsidiary is bound.

No Personal Liability of Partners, Stockholders, Officers, Directors
 
      The Indenture provides that no direct or indirect stockholder (or
partner, limited liability company member or employee of a stockholder),
employee, officer or director, as such, past, present or future of the Co-
Obligors or any successor entity or any Affiliate thereof shall have any
personal liability in respect of the obligations of the Co-Obligors under the
Indenture or the notes by reason of his or its status as such stockholder,

Governing Law
 
      The Indenture, the notes and any Guarantee will be governed by, and
construed in accordance with, the laws of the State of New York, without giving
effect to the conflicts of law principles thereof.
 
Concerning the Trustee
 
      The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of Centennial or the Issuer, to obtain payment of
claims in certain cases, or to realize on certain property received in respect
of any such claim as security or otherwise. The Trustee will be permitted to
engage in other transactions; however, if it acquires any conflicting interest
it must eliminate such conflict within 90 days, apply to the SEC for permission
to continue as Trustee with such conflict or resign as Trustee.
 
      The holders of a majority in principal amount of the then outstanding
Notes will have the right to direct the time, method and place of conducting
any proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
occurs (which has not been cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any holder of notes unless such holder shall have offered to
the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

Book-Entry Delivery And Form
 
      The Global Note. The certificates representing the old notes were issued,
and the certificates representing the new notes will be issued, in fully
registered form, without coupons. The Old Notes are represented by one or more
permanent global certificates in definitive, fully registered form without
interest coupons in an aggregate amount of $370 million (the "Initial Global
Note"). Except as described in the next paragraph, the new notes initially will
be represented by one or more permanent global certificates in definitive,
fully registered form (the "Global Notes") and will be deposited with, or on
behalf of, the DTC (the
 
                                      111
<PAGE>
 
"Depositary"), and registered in the name of Cede & Co., as the DTC's nominee
or will remain in the custody of the Trustee pursuant to a FAST Balance
Certificate Agreement between the DTC and the Trustee. If any holder of old
notes whose interest in such old notes is represented by the Initial Global
Note fails to tender in the exchange offer, we may issue and deliver to such
holder a separate certificate representing such holder's old notes in
registered form without interest coupons.
 
      Certain Book-Entry Procedures for Global Notes. The descriptions of the
operations and procedures of DTC that follow are provided solely as a matter of
convenience. These operations and procedures are solely within the control of
the respective settlement systems and are subject to change by them from time
to time. The Issuer takes no responsibility for these operations and procedures
and urges investors to contact DTC or its participants directly to discuss
these matters.
 
      DTC has advised the Issuer as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its participants ("participants") and facilitate the clearance
and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical transfer and delivery of certificates.
Participants include securities brokers and dealers, banks, trust companies and
clearing corporations and may include certain other organizations. Indirect
access to the DTC system is available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly ("indirect
participants").
 
      Pursuant to procedures established by DTC, (i) upon the issuance of the
Initial Global Certificate, DTC credited, on its internal system, the
respective principal amount of the individual beneficial interests represented
by such Global Notes to the accounts with DTC of the participants through which
such interests are held and (ii) ownership of beneficial interest in the Global
Notes are shown on, and the transfer of that ownership is effected only
through, records maintained by DTC or its nominees (with respect to interest of
participants) and the records of participants and indirect participants (with
respect to interests of persons other than participants).
 
      As long as DTC, or its nominee, is the registered Holder of a Global
Note, DTC or such nominee, as the case may be, will be considered the sole
owner and Holder of the Notes represented by such Global Note for all purposes
under the Indenture and the notes. Except in the limited circumstances
described below, owners of beneficial interests in a Global Note will not be
entitled to have any portions of such Global Note registered in their names,
and will not receive or be entitled to receive physical delivery of Notes in
definitive form and will not be considered the owners or Holders of the Global
Note (or any Notes represented thereby) under the Indenture or the notes.
 
      The laws of some states require that certain persons take physical
delivery in definitive form of securities that they own. Consequently, the
ability to transfer beneficial interests in a Global Note to such persons may
be limited to that extent. Because DTC can act only on behalf of its
participants, which in turn act on behalf of indirect participants and certain
banks, the ability of a person having beneficial interests in a Global Note to
pledge such interest to persons or entities that do not participate in the DTC
system, or otherwise take actions in respect of such interests, may be affected
by the lack of a physical certificate evidencing such interests.
 
      Payments of the principal of, premium, if any, and interest on Global
Notes will be made to DTC or its nominee as the registered owner thereof.
Neither the Issuer, the Trustee nor any of their respective agents will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interest in the Global Notes
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
 
                                      112
<PAGE>
 
      The Issuer expects that DTC or its nominee, upon receipt of any payment
of principal of, premium, if any, or interest in respect of a Global Note
representing any notes held by it or its nominee, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note for such notes as shown
on the records of DTC or its nominee. The Issuer also expects that payments by
participants to owners of beneficial interests in such Global Note held through
such participants will be governed by standing instructions and customary
practices, as is now the case with securities held for the accounts of
customers registered in "street name." Such payments will be the responsibility
of such participants. None of the Issuer or the Trustee will be liable for any
delay by DTC or any of its participants in identifying the beneficial owners of
the notes, and the Issuer and the Trustee may conclusively rely on and will be
protected in relying on instructions from DTC or its nominee as the registered
owner of the notes for all purposes.
 
      Interests in the Global Notes will trade in DTC's Same-Day Funds
Settlement System and secondary market trading activity in such interests will
therefore settle in immediately available funds, subject in all cases to the
rules and procedures of DTC and its participants. Transfers between
participants in DTC will be effected in accordance with DTC's procedures, and
will be settled in same-day funds.
 
      DTC has advised the Issuer that it will take any action permitted to be
taken by a holder of notes only at the direction of one or more participants to
whose accounts with DTC interests in the Global Notes are credited and only in
respect of such portion of the aggregate principal amount of the notes as to
which such participant or participants has or have given such direction.
However, if there is an Event of Default under the notes, DTC reserves the
right to exchange the Global Notes for Notes in certificated form, and to
distribute such Notes to its participants.
 
      Although DTC has agreed to the foregoing procedures in order to
facilitate transfer of beneficial ownership interests in the Global Notes among
participants of DTC, it is under no obligation to perform or continue to
perform such procedures, and such procedures may be discontinued at any time.
None of the Issuer, the Trustee nor any of their respective agents will have
any responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing its operations, including maintaining, supervising or reviewing the
records relating to or payments made on account of, beneficial ownership
interests in Global Notes.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
      The summary below describes the material United States federal income tax
consequences of the exchange of old notes for new notes as of the date hereof.
The discussion below is based upon the provisions of the Internal Revenue Code
of 1986, as amended, and regulations, rulings and judicial decisions thereunder
as of the date hereof, and such authorities may be repealed, revoked or
modified so as to result in federal income tax consequences different from
those discussed below. You should consult their own tax advisors concerning the
federal income tax consequences in light of their particular situations as well
as any consequences arising under the laws of any other taxing jurisdiction.
 
Exchange of Notes
 
      The exchange of old notes for new notes pursuant to the exchange offer
should not be treated as an "exchange" for federal income tax purposes, because
the new notes should not be considered to differ materially in kind or extent
from the old notes. Rather, the new notes received by you should be treated as
a continuation of your old notes. As a result, there should be no federal
income tax consequences to you if you exchange notes for new notes pursuant to
the exchange offer.
 
                              PLAN OF DISTRIBUTION
 
      Each broker-dealer that receives new notes for its own account pursuant
to the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new notes received in exchange for old notes where
such old notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. We have agreed that, for a period of 90
days after the expiration date of the exchange offer, we will make this
prospectus available to any broker-dealer for use in connection with any such
resale. In addition, for a period of 90 days after the expiration date, all
dealers effecting transactions in the new notes may be required to deliver a
prospectus.
 
      We will not receive any proceeds from any sale of new notes by broker-
dealers. New notes received by broker-dealers for their own account pursuant to
the exchange offer may be sold from time to time in one or more transactions in
the over-the-counter market, in negotiated transactions, through the writing of
options on the new notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or at negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such new notes. Any broker-dealer that resells new notes that
were received by it for its own account pursuant to the exchange offer and any
broker or dealer that participates in a distribution of new notes may be deemed
to be an "underwriter" within the meaning of the Securities Act, and any profit
on any such resale of new notes and any commissions or concessions received by
any such person may be deemed to be underwriting compensation under the
Securities Act. The letter of transmittal states that a broker-dealer will not
be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act by acknowledging that it will deliver and by delivering a
prospectus. We have no arrangement or understanding with any broker or dealer
to distribute the New Notes received in the exchange offer.
 
      For a period of 90 days after the expiration date we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests such documents in the letter of
transmittal.

      The validity of the New Notes will be passed upon for us by Reboul,
MacMurray, Hewitt, Maynard & Kristol, New York, New York.

            UNCERTAINTIES ASSOCIATED WITH FORWARD-LOOKING STATEMENTS
 
      This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties and assumptions about us, including, among other things:
 
     .  Our high degree of leverage and the requirement for significant and
        sustained growth in our cash flow to meet our debt service
        requirements,
 
     .  That we are a holding company and the notes are structurally
        subordinated to all indebtedness of our subsidiaries, including
        guarantees by our subsidiaries of all indebtedness under our $1.05
        billion credit facility (approximately $930 million of which was
        drawn at closing of the merger and a portion of which was borrowed
        directly by our Puerto Rico subsidiary),
 
     .  Our history of net losses and the expectation of future losses,
 
     .  That the telecommunications industry is highly competitive,
 
     .  That new technologies or new business opportunities will require
        additional investments in network capacity or additional capital
        spending,
 
     .  That the success of any acquisitions will depend on our ability to
        integrate acquired businesses,
 
     .  That the telecommunications industry is subject to rapid and
        significant changes in technology,
 
     .  That there is potential for adverse regulatory change and the need
        for regulatory approvals in the operation of our business and
        renewal of our cellular licenses,
 
     .  Fluctuations in market value of our licenses,
 
     .  Risks associated with the regional economic conditions in the areas
        we operate our business,
 
     .  Operating costs due to fraud,
 
     .  That a decline in roaming rates may materially adversely affect us,
 
     .  That a dispute regarding reverse billing may materially adversely
        affect us,
 
     .  That the indenture governing the notes will require us to offer to
        purchase all of the notes issued and outstanding upon any change of
        control and that the credit facility contains similar provisions,
        which purchases, in each case, we may not have sufficient funds to
        consummate,
 
     .  That the indenture and the credit facility impose significant
        operating and financial restrictions on Centennial Cellular
        Operating,
 
 
                                      115
<PAGE>
 
     .  That Centennial Cellular Operating has pledged the capital stock of
        all its direct and indirect subsidiaries to the lenders under the
        credit facility and that all of the assets of such subsidiaries are
        pledged to such lenders,
 
     .  That Centennial has unconditionally guaranteed the obligations of
        the borrowers under the credit facility,
 
     .  That Centennial, as co-obligor, has no assets other than the stock
        of Centennial Cellular Operating and Centennial is not subject to
        the covenants contained in the indenture governing the notes,
 
     .  That the right of the trustee under the indenture and a pledge and
        escrow agreement to obtain payment on the notes upon the occurrence
        of an event of default may be significantly impaired by applicable
        bankruptcy law,
 
     .  The lack of certainty with respect to how a court might decide a
        suit by an unpaid creditor on the basis of fraudulent conveyance,
 
     .  The potential effect of Year 2000 computer issues,
 
     .  Risks associated with new management and any future changes in
        management,
 
     .  That certain equity investors control Centennial and its
        subsidiaries and have the power to elect directors and take other
        corporate actions,
 
     .  That we have limited ability to direct the operations of the systems
        in which we hold minority cellular investment interests as a limited
        partner and that our interests in such systems may be diluted if we
        do not meet a capital call,
 
     .  The potential effect of equipment failure or natural disaster on our
        business,
 
     .  Concerns about radio frequency emissions from cellular handsets, and
 
     .  The absence of a public market for the new notes.
 
      We are not obligated to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.
In light of these risks, uncertainties and assumptions, the forward-looking
events discussed in this prospectus might not occur.

Item 20. Indemnification of Directors and Officers
 
      Section 145 of the General Corporation Law of the State of Delaware
("DGCL") empowers a Delaware corporation to indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of such corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of such corporation, or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation or
enterprise. A corporation may indemnify such person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. A Delaware corporation may indemnify officers
and directors in an action by or in the right of the corporation to procure a
judgment in its favor under the same conditions, except that no indemnification
is permitted without judicial approval if the officer or director is adjudged
to be liable to the corporation. Where an officer or director is successful on
the merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses (including attorneys' fees)
which he actually and reasonably incurred in connection therewith. The
indemnification provided is not deemed to be exclusive of any other rights to
which an officer or director may be entitled under any corporation's by-law,
agreement, vote or otherwise.
 
      In accordance with Section 145 of the DGCL, Centennial Cellular Corp.
("Centennial") has adopted a by-law that provides that, to the fullest extent
permitted by DGCL, Centennial shall indemnify any person serving as a director
or officer of Centennial and every such director or officer serving at the
request of Centennial as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise for expenses
incurred in the defense of, or in connection with, any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative. Under Section 145 of the DGCL and Centennial's by-laws, such
indemnification shall not be deemed exclusive of any other rights to which
those seeking indemnification may be entitled under any by-law, agreement, vote
of stockholders or disinterested directors or otherwise, both as to action in
his official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.
 
      Section 18-108 of the Delaware Limited Liability Company Act (the "LLC
Act") empowers a Delaware limited liability company to indemnify and hold
harmless any member or manager or other person from and against any and all
claims and demands whatsoever. In accordance with such section, the limited
liability company agreement of Centennial Cellular Operating Co. LLC
("Centennial Cellular Operating") provides that, to the fullest extent
permitted by the LLC Act, Centennial Cellular Operating shall indemnify a
member, any affiliate of a member, any officers, directors, shareholders,
partners, employees, representatives or agents of a member, or their respective
affiliates, or any employee or agent of Centennial Cellular Operating or its
affiliates (each, a "Covered Person") for any loss, damage or claim incurred by
such Covered Person by reason of any act or omission performed or omitted by
such Covered Person in good faith on behalf of Centennial Cellular Operating
and in a manner reasonably believed to be within such Covered Person's scope of
authority.
 
      Each of Centennial and Centennial Cellular Operating has purchased and
maintains insurance to protect persons entitled to indemnification pursuant to
its by-laws or limited liability company agreement (as the case may be), the
DGCL or the LLC Act against expenses, judgments, fines and amounts paid in
settlement, to the fullest extent permitted by the DGCL or the LLC Act (as the
case may be).
