                           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 as a result of the
merger of Centennial and CCW Acquisition Corp.

                           Centennial Cellular Corp.

      Our company is one of the largest independent wireless telecommunications
service providers in the United States and Puerto Rico with approximately
426,700 subscribers as of February 28, 1999. Our domestic rural cellular
systems provide service in areas with an aggregate population of 5.8 million,
adjusted for our percentage ownership in entities serving these areas, and
these systems cover approximately 81,645 square miles. This adjusted population
is commonly referred to as net pops. Our subsidiary in Puerto Rico is a
provider of wireless, local telephone, long distance and internet
communications services in Puerto Rico. These operations use a license that
covers a population of 3.8 million net pops in Puerto Rico and the U.S. Virgin
Islands and a competitive local telephone service 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.

Our Principal Executive Offices

      The address of our principal executive offices is 1305 Campus Parkway,
Neptune, New Jersey 07753. Our telephone number is (732) 919-1000. Centennial
is the sole member of Centennial Cellular Operating and holds all of its
material assets through Centennial Cellular Operating.

Risk Factors

      You should consider all of the information in this prospectus before
tendering your outstanding notes in the exchange offer. The risks of an
investment in Centennial and Centennial Cellular Operating include our
substantial indebtedness, our history of net losses, competitive conditions and
the potential for adverse regulatory impact. See the "Risk Factors" section of
this prospectus for a discussion of these and other risks involved in an
investment in Centennial and Centennial Cellular Operating.

The Merger

      On January 7, 1999, Centennial merged with CCW acquisition Corp. As a
result of the merger, a new group of equity investors acquired a 92.9%
ownership interest in Centennial. The remaining 7.1% interest is owned by
public stockholders. We entered into several financings, including the issuance
of the old notes, in order to fund the merger. See "The Merger" for a more
complete description.

                   Summary of the Terms of the Exchange Offer

      On December 14, 1998, we completed the private offering of $370.0 million
principal amount of our 10 3/4% Senior Subordinated Notes due 2008. In
connection with that offering, we agreed, among other things, to deliver to you
this prospectus and to use our best efforts to complete the exchange offer by
July 6, 1999.

The Exchange Offer

      We are offering to exchange an equal principal amount of our 10 3/4%
Senior Subordinated Notes due 2008, which have been registered under the
Securities Act, for our outstanding 10 3/4% Senior Subordinated Notes due 2008.
In order to be exchanged, an outstanding note must be properly tendered and
accepted. You may tender outstanding notes only in integral multiples of
$1,000.

      As of this date, there is $370.0 million principal amount of notes
outstanding. The exchange offer will be completed regardless of whether all or
less than all of the outstanding notes are tendered for exchange.

Expiration Date

      The exchange offer will expire at 5:00 p.m., New York City time,      ,
1999, unless we decide to extend the expiration date.

copy of the letter of transmittal delivered with this prospectus, or a
facsimile of the letter of transmittal, and all other documents required by the
letter of transmittal, together with certificates for your outstanding notes,
to Norwest Bank Minnesota, National Association, as exchange agent for the
exchange offer. In the alternative, you can tender your old notes by book-entry
delivery following the procedures described in this prospectus in "The Exchange

Special Procedures for Beneficial Owners

     If you wish to tender outstanding notes that are registered in the name
of a broker, dealer, commercial bank, trust company or other nominee, you
should promptly instruct the registered holder to tender on your behalf. If
you wish to tender on your own behalf, you must, prior to completing the
procedures described above under the heading "Procedures for Tendering
Outstanding Notes," either register ownership of the outstanding notes in your
name or obtain a properly completed bond power from the registered holder.

Withdrawal Rights

     You may withdraw the tender of your notes at any time prior to 5:00 p.m.,
New York City time, on the expiration date.

Certain U.S. Federal Income Tax Consequences

     The exchange of new notes for outstanding notes in the exchange offer
will generally not be a taxable event for United States federal income tax
purposes.

Conditions to the Exchange Offer

     The exchange offer is not subject to any conditions other than that it
does not violate applicable law or any applicable interpretation of the SEC
staff.

Use of Proceeds

     We will not receive any proceeds from the issuance of the new notes in
the exchange offer.

                  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. If any of these statements
are untrue, you may not resell your notes unless an exemption from the
registration provisions of the Securities Act is available for the transfer or
you resell your notes in compliance with the prospectus delivery provisions of
the Securities Act.

                                       5
<PAGE>


      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 CUSIP 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. Centennial Cellular and Centennial Cellular Operating are each
liable for repayment of the 10 3/4% Senior Subordinated Notes. Centennial
Cellular is a holding company and does not conduct any direct business
operations.

Maturity

      December 15, 2008.

Interest Payment Dates

      We will pay interest on the notes on June 15 and December 15 of each
year, beginning June 15, 1999.

                                       6
<PAGE>


Ranking

      The notes are subordinated to all our senior debt, including all our debt
under our senior secured credit facility. The notes rank equally with any
senior subordinated debt, and rank senior to all our subordinated debt. Both
Centennial and Centennial Operating are holding companies. The notes are
neither guaranteed by our subsidiaries nor secured by their assets, so they
will effectively rank below all debt of our subsidiaries, including money we
owe to our suppliers. Our ability to pay interest on the notes and to redeem
the notes at maturity will depend on whether our subsidiaries can pay dividends
and make other distributions to us.

      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 our
        subsidiary in Puerto Rico, which has not initially guaranteed this
        debt.

      The notes are senior to a face amount of $180 million 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
any accrued interest to the date of repurchase. In addition, if the change of
control occurs before December 15, 2003, we may elect to redeem the notes at
100% of their principal amount, plus interest, if any, to the date of
redemption, plus a computed premium, which will not be less than 5.375%.

                                       7
<PAGE>


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 debt,

     .  pay dividends on, redeem or repurchase our capital stock,

     .  make investments,

     .  restrict dividend or other payments to us,

     .  enter into transactions with affiliates or related persons,

     .  guarantee indebtedness,

     .  sell assets,

     .  create liens,

     .  engage in a merger, sale or consolidation, and

     .  enter into new lines of business.

      These covenants are subject to important exceptions and qualifications,
which are described under the heading "Description of the New Notes--Covenants"
in this prospectus.

                    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

     representing that portion of rental expense deemed to be attributable to
     interest. The ratio of earnings to fixed charges is less than one-to-one
     for all periods presented and, therefore, earnings are inadequate to cover
     fixed charges. The amount by which earnings are less than fixed charges
     for the nine months ended February 28, 1999 and 1998 are $56,993 and
     $39,272, respectively, and for the years ended May 31, 1998, 1997, 1996,
     1995 and 1994 are $45,382, $43,189, $33,412, $47,117 and $39,885,
     respectively.

 (4) Adjusted EBITDA is defined, for any period, as earnings before income from
     our 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
     commonly used to analyze companies on the basis of operating performance,
     leverage and liquidity. While Adjusted EBITDA should not be construed as a
     substitute for operating income or a better measure of liquidity than cash
     flow from operating activities, which are determined in accordance with
     generally accepted accounting principles. It is included in this
     prospectus because management believes that it provides additional
     information with respect to the anticipated ability of Centennial to meet
     future debt service, capital expenditures and working capital
     requirements.

 (5) As of period-end.

 (6) For the periods ended January 28, 1999 and 1998 and the years ended May
     31, 1998, 1997 and 1996, the number of Net Pops is based on the 1997
     Kagan's Cellular Telephone Atlas. 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 rural service area, as derived from the 1990
     U.S. Census data.

 (7) The penetration rate equals the percentage of total population in our
     service areas who are subscribers to our cellular service as of period-
     end.

 (8) ARPU is defined as total monthly revenue per average subscriber.

 (9) 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.

(10) Churn is defined as the number of wireless subscriber cancellations per
     month as a percentage of the weighted average total wireless subscribers
     at the beginning of the period. Churn is stated as the average monthly
     churn rate for the period.

Subsequent Event

      We have entered into an agreement to acquire 100% of the ownership
interests in a partnership owning the wireless telephone system serving the
Allegen, Michigan rural service area. The Allegen market represents
approximately 100,000 net pops. Our obligation to consummate this transaction
is subject to certain closing conditions, including the relevant regulatory
approvals. We have anticipated completing this acquisition in October 1999.

                                  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.

Risks Relating to the Notes

We expect to incur losses for the foreseeable future and may not be able to
generate enough cash to repay the notes.

      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. 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 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. In addition, prevailing economic conditions and financial,
business and other factors in the markets we serve, many of which are beyond
our control, will affect our ability to pay interest on the notes and satisfy
our other debt obligations.

Payment of our debt obligations reduces the cash available to use in our
business.

      After the merger our total long term debt was significantly greater than
before the merger. Our large amount of debt could adversely affect our business
and you because we must use a substantial portion of our cash to pay our debt
obligations. As a result, we have less cash to use in other areas of our
business. In addition, our debt service obligations increase our
vulnerabilities to:


     .  adverse economic and industry conditions;

     .  interest rate increases because borrowings under our credit facility
        are at variable interest rates; and

     .  competitive pressures, as many of our competitors will be less
        leveraged than we are.

      In addition, we may incur significantly more debt. This may further
reduce the cash we have available to invest in our operations. If 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.


Because the notes rank below our senior debt and below all debt of our
subsidiaries, you may not receive full payment on your notes.

      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 credit facility and other senior indebtedness, including the
liabilities of our subsidiaries. We cannot assure you that sufficient assets
will remain to make any payments on the notes. We and our subsidiaries also may
incur additional indebtedness that ranks senior to the notes.


                                       13
<PAGE>


We may not be able to repay the notes because our subsidiaries may not be
permitted to distribute cash to us.

      If we do not receive sufficient cash flow from our subsidiaries we will
not be able to make payments on the notes. We cannot assure that our
subsidiaries will have sufficient funds to distribute to us or that state
corporate laws will allow dividends to be paid. In addition, the terms of
existing and future debt of our subsidiaries may restrict our subsidiaries from
distributing cash to us. Our credit facility limits dividends from our
subsidiaries to a specified amount so long as no event of default exists under
the credit agreement. The indenture for the notes permits our subsidiaries to
enter into agreements which restrict dividends and distributions to us and the
subsidiaries have no legal obligation to pay dividends. See "Description of the
New Notes--Covenants--Limitation on Restrictions on Subsidiary Dividends."

Because the notes are unsecured, other lenders will have prior claims to our
assets in the event we become insolvent or are liquidated.

      The notes are not secured by any of our assets, other than the funds
pledged to pay the first three interest payments. 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. Our bank lenders will have a claim on
substantially all our assets before the holders of the notes. Accordingly,
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."

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.

      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, the holders of
the notes would be prohibited from foreclosing upon or disposing of the escrow
funds without prior bankruptcy court approval. See "Description of the New
Notes--Security."

We may not be able to satisfy our obligation to repurchase the notes upon a
change of control.

      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 all 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. The term "change of control" is
defined in the section "Description of the New Notes--Certain Definitions."

We may not be able to repay the notes if we default on our debt covenants.

      We or our subsidiaries may fail to comply with restrictions contained in
our debt instruments, even if we are otherwise able to meet our debt service
obligations. In the event of a default, the holders of our debt could elect to
declare all our debt, together with accrued interest, to

                                       14
<PAGE>


be due and payable. We cannot assure you that we or our subsidiaries would be
able to make these payments. Covenants contained in the instruments governing
the notes and our credit facility include, among other things, restrictions on
our ability to:

     .borrow more funds or create liens,

     .  repay indebtedness prior to stated maturities,

     .  sell assets,

     .  make investments and capital expenditures,

     .  engage in transactions with stockholders and affiliates,

     .  engage in mergers or acquisitions, or

     .  otherwise conduct necessary corporate activities.

We may encounter difficulties obtaining future financing on favorable terms.

      We cannot assure you that we will be able to borrow sufficient funds in
the future to satisfy our debt service and working capital requirements or to
finance our acquisition strategy. Even if we were to obtain additional
financing, such financing may be on terms unfavorable to us. Centennial
Cellular Operating has pledged as security to the lenders under its credit
facility the shares of all its direct and indirect subsidiaries other than the
shares of its foreign subsidiaries. The pledge of such shares could impair our
ability to obtain future financing on favorable terms, if at all. See
"Description of Certain Indebtedness."

Our holding company may not be able to make payments on the notes if our
operating subsidiary defaults on its obligations.

      Centennial is a co-obligor of the notes. Centennial 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 payments on the notes. In addition, Centennial is not
subject to the covenants of the indenture governing the notes. Accordingly,
Centennial may take actions that reduce its creditworthiness and adversely
affect its ability to repay the notes.

      Centennial has unconditionally guaranteed all obligations of 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 not likely be able to service or repay its
indebtedness, including the notes. See "Description of Certain Indebtedness."


Your rights to be repaid would be adversely affected if a court determined that
we issued the notes for inadequate consideration or with intent to defraud our
creditors.

      Our ability to repay the notes may be adversely affected if it is
determined in a bankruptcy, insolvency or similar proceeding that:

    .  we issued the notes with intent to delay or defraud any creditor,

    .  we contemplated insolvency with a design to prefer some creditors to
       the exclusion of others, or

                                       15
<PAGE>


    .  we issued the notes for less than reasonably equivalent value and
       were insolvent at the time the notes were originally issued.

      In such event, a court could, among other things, void all or a portion
of our obligations to you. In this case, you may not be repaid in full. A court
may also subordinate our obligations to you to our other indebtedness to a
greater extent than would otherwise be the case. In this case, other creditors
would be entitled 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 your claims.

If an active trading market does not develop, you may have difficulties
reselling the notes.


      The notes are securities for which there currently is no market. If the
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. In addition, substantial
volatility in the market for non-investment grade debt, such as the notes, may
have a material adverse effect on the holders of the notes. This volatility has
increased in recent months and the liquidity of non-investment grade securities
has declined significantly.

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 outstanding notes under the Securities Act. In such event, the
notes would rank equally with the outstanding notes. 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.

Risks Relating to Our Business

We may be adversely affected by our competitors, many of whom have greater
financial resources than we do.

      Our principal business, wireless telephone service, is highly
competitive. We compete with one cellular licensee in each geographic area.
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, traditional telephone companies and resellers. The FCC requires all
cellular and personal communication system operators to provide service on a
nondiscriminatory basis to resellers. Resellers 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.


                                       16
<PAGE>


We face increased competition from entities using communications technologies
comparable to cellular service.

      Competing technologies or any new technologies may 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. New technologies that are comparable to cellular
service include:

      .personal communications services,

      .ESMR and

      .satellite-based services.

      Personal communications services refer to the series of two-way
communication licenses recently awarded by the FCC which are expected to use
digital wireless technologies. 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.

      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.

      The FCC has issued a number of licenses for satellite-based services that
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.

Competition from other wireless and traditional telephone service providers in
Puerto Rico may reduce our market share and adversely affect prices.

      The market for wireless services is highly competitive in Puerto Rico.
Competition from these of telecommunications providers may reduce our market
share and have an adverse effect on our prices and profitability. Our main
competitors for wireless services in the Puerto Rico market are Cellular
Communications of Puerto Rico, Inc. and the Puerto Rico Telephone Company. Both
competitors were earlier entrants into the Puerto Rico wireless market, have
greater resources than we do. They currently hold subscriber market shares of
approximately 47% and 40%, respectively. Cellular Communications and the Puerto
Rico Telephone Company offer cellular service based on both analog and digital
technology and offer greater cellular capability than we do to their customers
traveling outside Puerto Rico. We only offer digital service in Puerto Rico.

      The FCC has issued large capacity personal communication services
licenses for the Puerto Rico market. These systems present additional
competition to our large capacity personal communication services operations in
Puerto Rico.

      The Puerto Rico Telephone Company is also our primary competitor for
traditional telephone service. GTE has bought a majority stake in the Puerto
Rico Telephone Company and may make

                                       17
<PAGE>


changes to improve its competitive position. Any increase in our market
presence will depend upon our ability to obtain customers that are underserved
by the Puerto Rico Telephone Company or looking for an alternative.



If we are successful in making acquisitions, the acquired properties may
adversely affect our business.

      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. We intend to expand our
current business in adjacent areas through acquisition and also to acquire
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.

      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,

    .integrate acquired properties,

    .maintain effective quality controls and

    .significantly expand our internal management, technical and accounting
    systems.

      Management of those areas 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.

Rapid and significant technological changes in the telecommunications industry
may adversely affect us.

      We 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.


                                       18
<PAGE>

      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.

We may not be able to modify our business to comply with regulatory changes.



      The telecommunications industry is subject to federal and state
regulation that is continually evolving. As new telecommunications laws and
regulations are issued, we may be required to modify our business plans or
operations. There can be no assurance that we can do so in a cost effective
manner. Further, we cannot assure you that federal or state governments or the
government of the Commonwealth of Puerto Rico will not make regulations or take
other actions that might have a material adverse effect on our business. If the
FCC allocates radio spectrum for services that compete with our business
thereby introducing additional competitors, these changes could materially and
adversely affect our business prospects, operating results or our ability to
service our indebtedness, including the notes.

      The FCC and state regulatory agencies continue to issue rules
implementing the requirements of the 1996 Telecommunications Act. Such rules
address obligations, which include the obligation of incumbent telephone
companies to allow other carriers to connect to their network by reasonable
means at rates based on cost. The interpretation of these and other provisions
of the 1996 Telecommunications Act and the FCC rules implementing the
Telecommunications Act continue to be heavily debated and subject to legal
challenges. The FCC has also made legal challenges against winners of personal
communication services licenses that have failed to pay for the licenses. These
challenges do not directly affect our operations because our licenses have
already been paid for.

The loss of our licenses could adversely affect our ability to provide wireless
and wireline services.

      Cellular and personal communications services licenses are valid for 10
years from the effective date of the license. Failure to file for such renewal
or failure to meet any licensing requirements could lead to a denial of the
application and thus adversely effect our ability to continue to provide
service in that license area. Licensees may renew their licenses for additional
ten year periods by filing a renewal application with the FCC. The renewal
applications are subject to FCC review and are put out for public comment to
ensure that the licensees meet their licensing requirements and comply with
other applicable FCC mandates.

      Our wireless subsidiary in Puerto Rico is a holder of a B Block personal
communication services license. The FCC requires that our subsidiary cover at
least one-third of the population of Puerto Rico in five years and two-thirds
of the population in ten years. Failure to meet these build-out requirements
could have a material effect on our ability to continue operations.

      Local telephone companies are subject to local state and municipal
regulation. These regulations often require that carriers be authorized to
provide local service via a franchise or licensing procedure. Lambda Operations
Corp., our wholly owned telephone subsidiary, falls under such regulation.
Lambda is subject to the regulation of the Puerto Rico Telecommunications Board
and is authorized to connect customers to the local telephone network and to
provide local telephone service. The Puerto Rico Telecommunications Basis rules
require that carriers file their tariffs and

                                       19
<PAGE>


applicable rates. Such tariffs and rates are subject to review by the Puerto
Rico Telecommunications Board to ensure that those rates are cost based and
that the tariffs are in the public interest.

      Both the wireless and local telephone subsidiaries are subject to siting
and zoning regulation which could materially affect our ability to build new
sites and expand our coverage. All telecommunication providers are obligated to
contribute to the federal universal fund based upon a percentage of interstate
revenue. Universal service funds are used to provide local telephone service to
individuals or families qualifying for federal assistance or households in
areas not served by the local telephone company. Many states, including those
we operate in, are implementing local universal service programs that would
also require carriers to contribute additional funds.



Our cellular licenses may decrease in value, reducing the asset base that
supports our debt.

      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 and our ability to sell
assets to repay debt would be significantly affected.

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
telephone 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 adjusted
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. 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.

A substantial increase in fraudulent and/or unbilled use of our network would
affect our business operations.

      We incur costs associated with unauthorized use of our network. Fraud
adversely affects our business by increasing:

  .interconnection costs,

  .capacity costs,


                                       20
<PAGE>


  .administrative costs,

  .costs incurred for fraud prevention and

  .payments to other carriers for unbillable fraudulent roaming.

We cannot assure you that costs associated with unauthorized use of our
cellular network will not become substantial in the future.

Our results of operations may decline because of a market decline in roaming
rates and our strategy of aggressively pricing roaming rates.

      We earn much of our revenue from customers of other wireless
communications providers who enter our service areas and use their wireless
phones. Roaming rates per minute under reciprocal roaming arrangements have
declined over the last several years and we expect that such declines will
continue for the foreseeable future. We have also 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. Our results of operations
may decline because the decline in roaming rates may not be offset by the
decrease in roaming expenses we pay to other cellular and personal
communication services providers for roaming changes incurred by our
subscribers in other calling regions.

Our operations in Puerto Rico may be adversely affected if changes in tax
benefits available to businesses in Puerto Rico cause companies to reduce their
business activities in Puerto Rico.

      The demand for our services in Puerto Rico is significantly affected by
the level of business activity in the island providing tax incentives for U.S.
companies to operate in Puerto Rico and to reinvest the earnings from their
Puerto Rico operations in Puerto Rico. As a result of a 1996 amendment to the
Internal Revenue Code, the tax benefits available to corporations 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. Our business in
Puerto Rico may be adversely affected by such changes in the tax law.

The 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.

      The Year 2000 issue is the result of many computer programs being written
abbreviating dates by using two digits rather that four digits in the year
field. As a result, unless corrected, a computer program that has date
sensitive software may recognize a date using "00" in the year field as 1900
rather than the year 2000. This could result in system failures and errors
causing disruptions to various aspects of our business, including computer
systems, voice and data networks and building infrastructures.

      We currently believe that our worst case scenario with respect to the
Year 2000 may involve the interruption of telecommunications services and/or
interruption of customer billing. Either or both of these events could have a
material adverse effect on our financial condition, results of operations or
cash flows.

                                       21
<PAGE>


      Most of our customer-related computer systems and databases, including
our billing systems, are managed by third parties under contractual
arrangements. We have been informed by these third parties that the remediation
efforts are in various stages with final completion anticipated in September
1999.

      Our systems are interconnected with various networks and systems operated
by third parties, including traditional land-based communications networks,
long-distance networks, the networks of other wireless service providers as
well as public utilities. The operators of these networks and systems are
responsible for addressing the Year 2000 issue in their own systems. The
ability of our systems to operate, including the ability to provide wireless
service, is dependent upon these third party networks and systems being Year
2000 compliant. We have requested information from these vendors in order to
determine to what extent we may be exposed to their failure to correct their
own year 2000 problems. While many of these third parties have indicated to us
that they are or anticipate being Year 2000 compliant prior to December 31,
1999, we cannot assure you that these third parties will have taken the
necessary corrective actions prior to the year 2000.




Our management team is newly-formed and has not yet demonstrated its
effectiveness in managing Centennial.

      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 had no
prior experience managing our operations.

      The loss of any of our senior management employees could have a material
adverse effect on our company unless we can obtain a suitable replacement in a
timely manner. 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. In the event of vacancies in senior
management, the additional time and resources toward recruitment, hiring and
training to fill such positions, could result in a material adverse effect on
our business, prospects, operations or results of operations. If management
vacancies are not filled, 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.

A group of affiliated stockholders control the voting power of Centennial which
may have interests adverse to the interests of the holders of the notes.

      Welsh Carson VIII, certain of its affiliates and certain other equity
investors hold 92.9% of Centennial's outstanding shares of common stock.
Accordingly, these equity investors, 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. The equity
investors may make decisions that are adverse to your interests. 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--
Agreements between Centennial Cellular Corp. and Its Stockholders."

A portion of our operations are conducted through partnerships in which we have
a minority interest. We do not control such operations and are subject to
capital calls made by the controlling partner.

      We have a limited ability to direct the operation of any system conducted
through a partnership in which we 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 cannot assure you that we will be able to pay future 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. These partnerships accounted for none of our total revenues for the
fiscal year ended May 31, 1998.

Our operations may be adversely affected by equipment failures or by natural
disasters that disrupt our network.

      A major equipment failure or a natural disaster affecting any one of our
network control centers or certain of our wireless antenna 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.
Although we currently carry "business interruption" insurance, our insurance
policies may not entirely cover all damages we may suffer.

Possible health effects of radio frequency emission may adversely affect the
demand for cellular telephone services.

      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. There is no
assurance that government authorities would not increase regulation of cellular
telephones resulting from these concerns or that cellular telephone companies
may be liable for costs or damages associated with these concerns.

                                   THE MERGER

      On January 7, 1999, Centennial merged with CCW Acquisition Corp., a new
Delaware corporation organized by Welsh, Carson, Anderson & Stowe VIII, L.P. As
a result of the merger, a new group of equity investors acquired a 92.9%
ownership interest in Centennial. The remaining 7.1% interest is owned by
public stockholders. 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.

Merger Financing

      A total of approximately $1.87 billion was required to pay the cash
consideration to Centennial stockholders in the merger, repay our indebtedness,
pay fees and expenses related to the merger and its financing and purchase
pledged securities. The sources of funding for the merger and the related
transactions are described below.

    .  Equity Financing. Welsh, Carson, Anderson & Stowe VIII, L.P., certain
       of its affiliates, including WCAS Capital Partners III, L.P., certain
       affiliates of Blackstone Capital Partners, L.P. and certain other
       investors purchased $400 million in common shares of CCW Acquisition
       Corp. The CCW Acquisition Corp. shares were converted into Centennial
       common shares in the merger.

    .  Bank Financing. Centennial Cellular Operating and its Puerto Rico
       subsidiary borrowed approximately $936.0 million under a new $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" for a description
       of the credit facility's principal terms.

    .  High Yield Notes Financing. Centennial Cellular Operating, together
       with a co-obligor that has merged into Centennial, issued $370
       million of old notes on December 14, 1998.

    .  Subordinated Debt Financing. WCAS Capital Partners III, L.P., an
       investment partnership affiliated with Welsh Carson VIII, purchased
       unsecured subordinated notes due 2009 of Centennial and common shares
       of Centennial at an aggregate price of $180 million. See "Description
       of Certain Indebtedness" for a description of the principal terms of
       the subordinated debt.

                                USE OF PROCEEDS

      We will not receive any proceeds from the issuance of new notes in the
exchange offer. The offering of notes resulted in net proceeds to us 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:

      . fund payment of the cash consideration in the merger,

    .  repay or repurchase indebtedness of Centennial,

    .  pay the fees and expenses incurred in connection with the merger, the
       merger financings and related transactions, and

      .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:

- --------

(1) Our credit facility consists of three term loans in aggregate principal
    amount of $900.0 million and a revolving credit facility in an aggregate
    principal amount of up to $150.0 million. The borrowers under these
    facilities are Centennial Cellular Operating and, for $125.0 million of the
    term loans and up to $60.0 million of the revolving credit facility,
    Centennial de Puerto Rico. At the time of the merger, Centennial de Puerto
    Rico borrowed $36.0 million under the credit facility. Centennial, together
    with the subsidiaries of Centennial Cellular Operating, excluding initially
    Centennial de Puerto Rico and its subsidiaries, which subsidiaries have
    guaranteed the obligations of Centennial de Puerto Rico under the credit
    facility, have unconditionally guaranteed, jointly and severally, the debt
    under our credit 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

                                       27
<PAGE>

   scheduled interest payments on the notes at the stated interest rate. See
   "Description of the New Notes--Security."

(3) 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 and common shares of
    Centennial at an aggregate price of $180 million. This $180 million of
    financing has been allocated as $157.5 million debt and $22.5 million
    equity. The subordinated notes are obligations of Centennial only and,
    accordingly, pro forma financial information for Centennial Cellular
    Operating does not reflect any obligation for this debt.

(4) Includes $1,033.1 million in consideration for the Centennial common
    shares, $128.2 million in consideration for the Centennial common shares
    issued upon conversion of Centennial's preferred stock and $49.4 million
    in consideration for the settlement of outstanding options to purchase
    Centennial common shares and the settlement of restricted shares. The
    options were exercised or cancelled in exchange for a cash amount equal to
    the difference between $13.83 and the exercise price of the option
    immediately before the merger. The restricted shares were acquired in
    exchange for the cash amount of $13.83.

(5) Represents the amount required to repay our total pre-merger indebtedness
    and pay interest on our indebtedness and dividends on our then outstanding
    preferred stock. At the time of the merger, we repurchased 99.4% of our
    then outstanding 8 7/8% senior notes due 2001 and 99.8% of our then
    outstanding 10 1/8% senior notes due 2005. The amount shown includes
    accrued interest of $6.9 million and preferred dividends of $18.1 million.

(6) The amount required to pay the debt tender premiums associated with the
    debt tender offers for our notes due 2001 and 2005. The amount shown above
    includes the consent solicitation fees associated with the debt tender
    offers.

(7) Assumed for simplicity to be paid by Centennial and includes all fees and
    expenses related to the merger, the offering of old notes and related
    transactions.

                               THE EXCHANGE OFFER

Purpose of the Exchange Offer

      The holders of the notes currently are entitled to 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.

      Because the registration statement of which this prospectus forms a part
was not declared effective by the SEC by June 6, 1999, we have been paying
$2,569.00 per day in additional interest under the registration rights
agreement since such date. In addition, since the exchange offer was not
consummated by July 6, 1999, we will be paying an additional $2,569.00 per day
in additional interest under the registration rights agreement from such date
for an aggregate amount of $5,138.00 per day in additional interest. Once the
registration statement is declared effective, we will no longer be required to
pay $2,569.00 of such additional interest however, we will be required to pay
$2,569.00 of such additional interest per day until this exchange offer is
consummated.

      Upon the terms and subject to the conditions set forth in this prospectus
and in the accompanying letter of transmittal, we will accept all notes
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 old notes may be offered for resale,
resold and otherwise transferred by the holders other than any such holder that
is our "affiliate" within the meaning of the Securities Act or such holder that
is a broker-dealer, 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 could not rely on the position of the staff of the SEC in Exxon Capital
Holdings Corporation or similar interpretive letters and could not resell your
notes unless an exemption from the registration provisions of the Securities
Act is available for the transfer or you resell your notes in compliance with
the registration and prospectus delivery requirements of the Securities Act.

      Each broker-dealer that is issued new notes in the exchange offer for its
own account which were acquired by the broker-dealer as a result of market-
making activities 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 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

                                       29
<PAGE>

"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. See "Plan of Distribution."

      Except as described above, this prospectus may not be used for an offer
to resell, resale or other transfer of new notes.

      The exchange offer is not being made to, nor will we accept tenders for
exchange from, holders of old notes in any jurisdiction in which the exchange
offer or the acceptance of it would not be in compliance with the securities or
blue sky laws of such jurisdiction.

Terms of the Exchange Offer

      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 registered holders of old notes as
of the date of this prospectus.

      We will 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 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.

      Except as noted below, in the event the exchange offer is consummated, we
will not be required to register the old notes that are not tendered. In that
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--Risks Relating to the Notes."
Pursuant to the registration rights agreement, we are required to file a shelf
registration statement with the SEC if a holder of notes is not allowed to
participate in this exchange offer by law.

Expiration Date; Extensions

      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 make a public announcement of such
extension, 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.



Procedures for Tendering

      Unless the tender is being made in book-entry form, to tender in the
exchange offer, a holder must complete, sign and date the letter of
transmittal, or a facsimile of it,

     .  have the signatures guaranteed if required by the letter of
        transmittal and

                                       30
<PAGE>


     .  mail or otherwise deliver the letter of transmittal or the
        facsimile, the old notes and any other required documents, to the
        exchange agent prior to 5:00 p.m., New York City time, on the
        expiration date.

      Any financial institution that is a participant in DTC's system may make
book-entry delivery of the old notes by causing DTC to transfer the old notes
into the exchange agent's account. In connection with the delivery of old notes
through book-entry transfer into the exchange agent's account at DTC, the
letter of transmittal (or facsimile), with any required signature guarantees
and any other required documents or an agent's message (as described below),
must be transmitted to and received or confirmed by the exchange agent at its
addresses set forth under the caption "Exchange Agent," below, prior to 5:00
p.m., New York City time, on the expiration date. Delivery of documents to DTC
in accordance with its procedures does not constitute delivery to the exchange
agent.

      To effectively tender notes through DTC, the financial institution that
is a participant in DTC will electronically transmit its acceptance through the
Automatic Tender Offer Program. DTC will then edit and verify the acceptance
and send an agent's message to the exchange agent for its acceptance. The term
"agent's message" means a message transmitted by DTC, received by the exchange
agent and forming part of the book-entry confirmation, which states that DTC
has received an express acknowledgment from a participant in DTC that is
tendering old notes that are the subject of such book-entry confirmation; that
the participant has received and agrees to be bound by the terms of the
applicable letter of transmittal; and that we may enforce such agreement
against that participant. The exchange agent will make a request to establish
an account for the notes of DTC for the purposes of the exchange offer promptly
after the date of this prospectus.

      The method of delivery of old notes and the letter of transmittal and all
other required documents to the exchange agent is at the election and risk of
the holders. Instead of delivery by mail, we recommend that holders use an
overnight or hand delivery service. In all cases, holders should allow
sufficient time to assure delivery to the exchange agent before the expiration
date. No letter of transmittal of old notes should be sent to us. Holders may
request their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the tenders for such holders.

      Any beneficial owner whose old notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder to tender on behalf of the beneficial owner. If the
beneficial owner wishes to tender on that owner's own behalf, the owner must,
prior to completing and executing the letter of transmittal and delivery of
such owner's old notes, either make appropriate arrangements to register
ownership of the old notes in the owner's name or obtain a properly completed
bond power from the registered holder. The transfer of registered ownership may
take considerable time.

      Signature on a letter of transmittal or a notice of withdrawal, must be
guaranteed, unless the old notes tendered pursuant thereto are tendered:

     .  by a registered holder who has not completed the box entitled
        "Special Issuance Instructions" or "Special Delivery Instructions"
        on the letter of transmittal, or

     .  for the account of an eligible institution (as described below).

                                       31
<PAGE>


      In the event that signatures on a letter of transmittal or a notice of
withdrawal, are required to be guaranteed, such guarantee must be by an
eligible institution.

      An "eligible institution" is a member firm of a registered notional
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an eligible guarantor institution within the meaning of the
Exchange Act, which is a member of the Securities Transfer Agents Medallion
Program or the Stock Exchange Medallion Signature Program.

      If the letter of transmittal is signed by a person other than the
registered holder of any old notes, the old notes must be endorsed by the
registered holder or accompanied by a properly completed bond power signed by
the registered holder.

      If the letter of transmittal or bond powers are signed or endorsed by
trustees, executors, administrators, guardians, attorney-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by us, submit
evidence satisfactory to us of their authority to act in that capacity with the
letter of transmittal.

Guaranteed Delivery Procedures

      If you desire to accept the exchange offer, and

     .  certificates for the old notes are not immediately available,

     .  time will not permit a letter of transmittal or notes to reach the
        exchange agent before the expiration date, or

     .  the procedure for book-entry transfer cannot be completed on a
        timely basis,

a tender may be effected if the exchange agent has received at its addresses
set forth under the caption "Exchange Agent" below prior to 5:00 p.m., New York
City time, on the expiration date from an eligible institution a properly
completed and duly executed notice of guaranteed delivery, substantially in the
form provided by us, setting forth:

     .  the name and address of the registered holder,

     .  the certificate numbers of the old notes,

     .  the principal amount of such notes to be tendered,

     .  stating that the tender is being made thereby and

     .  guaranteeing that within five New York Stock Exchange trading days
        after the expiration date, the old notes, in proper form for
        transfer, or a confirmation of book-entry transfer of such notes
        into the exchange agent's account at DTC, will be delivered by such
        eligible institution together with a properly completed and duly
        executed letter of transmittal, and any other required documents,
        or, if applicable, an agent's message in lieu of the letter of
        transmittal.

  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

                                       32
<PAGE>


of transmittal and any other required documents or, if applicable, an agent's
message in lieu of the letter of transmittal, we may, at our option, reject the
tender.

Acceptance of Old Notes for Exchange

      The tender by a holder of old notes will constitute an agreement between
us and the holder in accordance with the terms and subject to the conditions
set forth in this prospectus and in the letter of transmittal.

      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 defect or irregularity in the tender of
any notes. In addition, we reserve the right to waive any of the conditions of
the exchange offer in our reasonable discretion.

      Our interpretation of the terms and conditions of the exchange offer
(including the instructions in the letter of transmittal) will be final and
binding, on all parties. Unless waived, any defects or irregularities in
connection with tenders of old notes must be cured within a time period we will
determine. Although we intend to request the exchange agent to notify holders
of defects or irregularities relating to tenders of old notes, neither we, the
exchange agent nor any other person will have any duty or incur any liability
for failure to give such notification. Tenders of old notes will not be
considered to have been made until such defects or irregularities have been
cured or waived. Any old notes received by the exchange agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned by the exchange agent to the tendering
holders, unless otherwise provided in the letter of transmittal, as soon as
practicable following the expiration date.

      By tendering, you will represent to us that, among other things,

     .  the new notes acquired pursuant to the exchange offer are being
        obtained in the ordinary course of your business,

     .  you have no arrangement with any person to participate in the
        distribution of such new notes,

     .  you are not an "affiliate," as defined under the Securities Act, of
        us, and

     .  if you are a broker or a dealer, as defined in the Exchange Act,
        that you acquired the old notes for your own account as a result of
        market-making activities or other trading activities and that you
        will comply with the registration and prospectus delivery
        requirements of the Securities Act.





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 under
the caption "Exchange Agent" below prior to 5:00 p.m., New York City time, on
the expiration date. Any such notice of withdrawal must:

     .  specify the name of the person having deposited the notes to be
        withdrawn,

     .  identify the notes to be withdrawn (including the certificate number
        or numbers and principal amount of such notes) or, in the case of
        old notes transferred by book-entry transfer, the name and number of
        the account at DTC to be credited,

                                       33
<PAGE>


     .  be signed by the person having deposited the notes to be withdrawn
        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 person
        having made the original tender and withdrawing the tender, and

     .  specify the name in which any such notes are to be registered, if
        different from that of the person having deposited the notes to be
        withdrawn.

      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 old notes you
withdraw 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 old notes so withdrawn are validly retendered. Any old notes that
have been tendered but that are not accepted for exchange will be returned to
you 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.

Conditions

      The exchange offer is not subject to any conditions other than that the
exchange offer does not violate applicable law or any applicable interpretation
of the staff of the SEC.

Accounting Treatment

      The new notes will be recorded at the same carrying value as the old
notes as reflected in our accounting records on the date of the exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes
upon the completion of the exchange offer. Any expenses of the exchange offer
that we paid will be capitalized and amortized over the term of the new notes.

(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) For the purposes of determining the ratio of earnings to fixed charges,
    earnings are defined as earnings before income taxes, minority interest and
    extraordinary items, plus fixed charges. Fixed charges include interest
    expense on all indebtedness, amortization of deferred debt issuance costs
    and one-third of rental expense on operating leases representing that
    portion of rental expense deemed to be attributable to interest. The ratio
    of earnings to fixed charges is less than one-to-one for all periods
    presented and, therefore, earnings are inadequate to cover fixed charges.
    The amount by which earnings are less than fixed charges for the nine
    months ended February 28, 1999 and 1998 are $56,993 and $39,272,
    respectively, and for the years ended May 31, 1998, 1997, 1996, 1995 and
    1994 are $45,382, $43,189, $33,412, $47,117 and $39,885, respectively.

(4) Adjusted 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 commonly used
    to analyze companies on the basis of operating performance, leverage and
    liquidity. While Adjusted EBITDA should not be construed as a substitute
    for operating income or a better measure of liquidity than cash flow from
    operating activities, which are determined in accordance with generally
    accepted accounting principles. It is included in this prospectus because
    management believes that it provides additional information with respect to
    the anticipated ability of Centennial to meet future debt service, capital
    expenditures and working capital requirements.

(5) As of period-end.

(6) For the periods ended January 28, 1999 and 1998 and the years ended May 31,
    1997 and 1996, the number of Net Pops is based on the 1997 Kagan's Cellular
    Telephone Atlas. 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.

(7) The penetration rate equals the percentage of total population in our
    service areas who are subscribers to our cellular service as of period-end.

(8) ARPU is defined as total monthly revenue per average subscriber.

(9) 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.

(10) Churn is defined as the number of wireless subscriber cancellations per
     month as a percentage of the weighted average total wireless subscribers
     at the beginning of the period. Churn is stated as the average monthly
     churn rate for the period.

Subsequent Event

      We have entered into an agreement to acquire 100% of the ownership
interests in a partnership owning the wireless telephone system serving the
Allegen, Michigan rual service area. The Allegen market represents
approximately 100,000 net pops. Our obligation to consummate this transaction
is subject to certain closing conditions, including the relevant regulatory
approvals. We have anticipated completing this acquisition in October 1999.

                     CENTENNIAL CELLULAR OPERATING CO. LLC

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

      We created the following pro forma consolidated financial statements by
making adjustments to our 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

      .financings related to the merger and

    .  the debt tender offers and the repayment or conversion of our other
       existing indebtedness.

      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 on 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 our 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.

      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)

      We created the following pro forma financial data by making adjustments
to our historical financial statements for the periods noted. The merger has
been accounted for as a recapitalization. Accordingly, the historical basis of
our 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 Welsh Carson 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:

                           Centennial Cellular Corp.

      Our company is one of the largest independent wireless communications
providers in the United States and Puerto Rico. Our service areas have a total
population of approximately 10.8 million, adjusted for our percentage ownership
in entities serving these areas. This adjusted population is commonly referred
to as net pops. We had 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,
provides wireless and traditional telephone services over a common
communications network in Puerto Rico. Its licensed service areas cover 3.8
million net pops in Puerto Rico and the U.S. Virgin Islands. In addition, we
own minority shares, representing approximately 1.2 million net pops, in 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. Adjusted 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. Net loss for the year ended May 31, 1998 was $31.9 million.

      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 since January
7, 1999complements the existing management team. Rudy J. Graf, currently
President and Chief Executive Officer of Centennial de Puerto Rico, who was the
Chief Operating Officer of Centennial since 1991, manages the day-to-day
operations of Centennial de Puerto Rico, our subsidiary inPuerto Rico.

Rural Cellular Systems

      Our domestic consolidated systems are among the leading independent
providers of rural non-wireline cellular telecommunications services. We
attempt to acquire cellular systems next to our existing markets. 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:

     .  Potential Penetration Growth. We believe these areas are in the
        early stages of their growth cycles and offer significant
        opportunities for increases in penetration of the market for users
        and potential users of cellular services and in cellular usage by
        subscribers;

     .  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. The population density of these regions suggests that
        the construction of a personal communications services network may
        not be economically attractive to competitors at present.

     .  Above-Average Revenue per Subscriber. Our domestic markets are
        strategically located between larger metropolitan areas and tend to
        exhibit long commute times and well-traveled roadways. Customers of
        other wireless communications providers who enter our service areas
        and use their wireless phones have the potential to generate high
        levels of cellular revenues. That use outside the subscriber's local
        area is commonly referred to as roaming.

      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,
Adjusted 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. Adjusted 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. Net loss for the year ended May 31, 1998 was $1.2
million. 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 our subsidiary in
Puerto Rico, provides a broad range of wireless and traditional telephone
services in the Commonwealth of Puerto Rico, an area covering approximately
3.8 million net pops. Centennial de Puerto Rico owns its own communications
network, making it a so-called "facilities-based" provider of communications
services. It is

    .   the only provider of personal communications services in the Puerto
        Rico market,

    .   a provider of wireless telephone services to both business and
        residential customers, and

    .   a provider of local and long distance telephone services and data
        services through its subsidiary, Lambda Operations, Inc., 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.

      Our subsidiary in Puerto Rico offers communications services using a
shared switch and its sophisticated fiber optic network, which contains over
314 miles of fiber laid 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 wireless antenna sites and
digital technology to transmit its calls.

     .  Wireless Services. Our subsidiary in Puerto Rico offers both
        personal communications services and wireless local telephone
        service to its customers.

     .  Personal Communications Services. Personal communication services
        refer to the series of two-way communication licenses recently
        awarded by the FCC which are expected to use digital wireless
        technologies. Our personal communications services business

        over our fiber optic network. We believe that our targeted 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 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 provided
        approximately 56.9 million minutes of use to its customers in
        February 1999, an increase of 155% over the minutes of use provided
        in May 1998.

      Since operations commenced in December 1996, our subsidiary in Puerto
Rico has achieved significant growth in subscribers, revenue and Adjusted
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. Adjusted EBITDA for the fiscal year ended May 31,
1998 was $12.5 million, compared to an Adjusted EBITDA deficit of $(8.4)
million for the prior period. Net loss for the year ended May 31, 1998 was

When CCW Acquisition Corp. was merged with our company on January 7, 1999, we
succeeded to all of the rights and obligations of CCW Acquisition Corp. under
the securities purchase agreement.

      Stockholders's Agreements. On January 7, 1999 each of the stockholders of
CCW Acquisition Corp. who purchased shares under the securities purchase
agreement and CCW Acquisition Corp. entered into a stockholders agreement. The
stockholders agreement became our obligation when we merged with CCW
Acquisition Corp. on January 7, 1999. The original stockholders agreement was
superceded by a first amended and restated stockholders agreement on January
20, 1999 in connection with the transfer by WCA Management Corporation of its
equity interest in our company to another investment fund.

      Under the amended and restated stockholders agreement, our principal
stockholders have agreed to establish and maintain for our company a board of
directors consisting of nine members. Our directors are elected as described
below.

    .  So long as the Welsh Carson investors own 25% of the Class A common
       shares purchased by them on January 7, 1999, they can elect three
       directors. Currently Thomas E. McInerney, Anthony J. de Nicola and
       Rudolph E. Rupert serve as the Welsh, Carson investors' board
       representatives. The chairman of our board of directors, who is
       currently Thomas E. McInerney, is selected by the Welsh Carson
       investors.

    .  So long as The Blackstone Group investors own 25% of the Class A
       common shares purchased by them on January 7, 1999, they can elect
       two directors. Currently Mark T. Gallogly and Lawrence H. Guffey
       serve as The Blackstone Group investors' board representatives.

    .  Our Chief Executive Officer (Centennial), who is currently Michael J.
       Small, serves on our board of directors.

    .  Our Chief Executive Officer (Centennial de Puerto Rico), who is
       currently Rudy Graf, serves on our board of directors.


                                       59
<PAGE>

    .  The remaining two directors are elected by all of our stockholders,
       including our principal stockholders. These outside directors must be
       qualified as outside directors under NASDAQ rules and cannot be
       members of our management or affiliated with any of our stockholders
       who are party to the amended and restated stockholders agreement.

      The amended and restated stockholders agreement calls for the creation of
the following board committees:

    .  A compensation committee consisting of three directors. Two of the
       committee members are selected by the Welsh Carson investors and one
       is selected by The Blackstone Group investors.

    .  An audit committee consisting of three directors. One audit committee
       member is selected by the Welsh Carson investors, one is selected by
       The Blackstone Group investors and one is required to be an outside
       director.

The amended and restated stockholders agreement requires that each other
committee of our board of directors consist of at least two members, one of
whom is selected by the Welsh Carson investors and one of whom is selected by
The Blackstone Group investors.

      The amended and restated stockholders agreement places restrictions on
the ability of Messrs. Small, Chehayl and Owen to transfer shares of Class A
common stock owned in their names or on their behalf without the consent of the
Welsh Carson investors. Exceptions have been made for transfers in registered
public offerings or to their spouses or children or to family trusts. In
addition, the amended and restated stockholders agreement allows the Welsh
Carson investors to repurchase at fair market value any shares owned by any of
these management investors at the time of the termination of their employment
with our company.

      The amended and restated stockholders agreement grants The Blackstone
Group investors, Messrs. Small, Chehayl and Owen, Signal/Centennial Partners,
L.L.C. and Guayacan Private Equity Fund, L.P. the right to participate in any
sale of Class A common shares by any of the Welsh Carson investors. These co-
sale provisions do not apply to transfers by Welsh Carson investors to
affiliates, transfers by any of the Welsh Carson investors that are limited
partnerships to their limited partners and transfers by Welsh Carson investors
that are individuals to their spouses or children or to family trusts.

      The amended and restated stockholders agreement grants the Welsh Carson
investors the right to require

    .  The Blackstone Group investors,

    .  Messrs. Small, Chehayl and Owen, and

    .  Signal/Centennial Partners, L.L.C. and Guayacan Private Equity Fund,
       L.P.

to sell their shares of Class A common stock to a third party who offers to buy
at least 80% of the capital stock of the company. The sale of the company must
be for cash or marketable securities and must require that we pay the fees and
expenses of the selling stockholders. This right will terminate if and when The
Blackstone Group investors own more shares of Class A common stock than the
Welsh Carson investors.

                                       60

      We have granted preemptive rights to purchase shares of our common stock
in proportion to the ownership of the stockholder in the situations described
below to

    .  the Welsh Carson investors,

    .  The Blackstone Group investors,

    .  Messrs. Small, Chehayl and Owen, and

    .  Signal/Centennial Partners, L.L.C. and Guayacan Private Equity Fund,
       L.P.

These preemptive rights apply to any sale by us of common shares or securities
convertible into or exchangeable for common shares such as convertible debt,
options or warrants. Issuances of employee stock options and registered public
offerings are excluded from the preemptive rights provisions of the amended and
restated stockholders agreement.

      The amended and restated stockholders agreement grants to the Welsh
Carson investors a right of first offer that applies to sales of Class A common
shares by The Blackstone Group investors. In other words, if any of The
Blackstone Group investors wishes to sell it shares, it must first allow the
Welsh Carson investors to make an offer to purchase the shares. If an offer is
made by any of the Welsh Carson investors, The Blackstone Group investors
cannot sell the shares to a third party on material terms which are the same
as, or more favorable, in the aggregate, to, the terms offered by the Welsh,
Carson investors for the shares. This right of first offer does not apply to
sales by The Blackstone Group investors to their affiliates, sales pursuant to
registered public offerings or sales in compliance with the Securities Act or
distributions by any of The Blackstone Group investors which are limited
partnerships to their limited partners.

      Our company has agreed not to take any of the following actions without

Former Indebtedness of Certain Executive Officers

      During fiscal 1998, Thomas R. Cogar, Senior Vice President of Engineering
of Centennial received a relocation loan from Centennial of approximately
$65,000 and John H. Casey, Senior Vice President--Administration of Centennial
received a relocation and temporary housing loan of approximately $200,000. The
loans bore interest at the rate of 5.0 % annually and have been repaid in full.

Arrangements with Former Controlling Stockholder

      At the time of the merger, Century Communications Corp., the controlling
stockholder of Centennial before the merger, entered into a non-compete
agreement with Centennial, in which Century agreed that, until January 7, 2002,
it will not engage in, or acquire a controlling interest in, any business that
competes with any of Centennial's current operations in Puerto Rico. This
agreement does not extend to the activities of Century's existing joint venture
in Puerto Rico, Century-ML.

      Century owned a controlling interest in Centennial prior to the merger.
Before the merger Centennial and Century 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 this 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 these costs were paid in full during the current fiscal year. In fiscal
1996, Centennial and Century also maintained combined group health, life and
casualty coverage. Under the merger agreement, Centennial has covenanted to
maintain employee benefits and incentive compensation that are no less
favorable than its existing arrangements at least until January 2002.

      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.

                                       64
<PAGE>

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 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.

The Merger and Subordinate Note Financing

      Welsh, Carson, Anderson & Stowe VIII, L.P. and its affiliates and The
Blackstone Group controlled CCW Acquisition Corp. prior to the merger. Messrs.
McInerney, de Nicola and Rupert, who are members of the general partner of
Welsh, Carson, Anderson & Stowe VIII, L.P., may be deemed to have controlled
CCW Acquisition Corp. prior to the merger. Messrs. Gallogly and Guffey, who are
affiliated with The Blackstone Group, may be deemed to have controlled CCW
Acquisition Corp. prior to the merger. For a description of the merger see "The
Merger."

      In addition, WCAS Capital Partners III, L.P., an investment partnership
affiliated with Welsh, Carson, Anderson & Stowe VIII, L.P. bought subordinated
notes of Centennial for $180 million at the time of the merger. Messrs.
McInerney, de Nicola and Rupert, who are members of the general partner of WCAS
Capital Partners III, L.P., may be deemed to control WCAS Capital Partners III,
L.P. See "The Merger."

    .a revolving credit facility in an aggregate principal amount of up to
          $150.0 million.


      The borrowers under these facilities are

    .Centennial Cellular Operating and

    .for $125.0 million of the term loans and up to $60.0 million of the
          revolving credit facility, Centennial de Puerto Rico, our
          subsidiary in Puerto Rico.

      On January 7, 1999, our subsidiary in Puerto Rico borrowed $36.0 million
under the credit facility.

      Use of Credit Facility Proceeds. The proceeds of our credit facility were
used, together with other proceeds of the financings related to the merger, 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 subject to the
conditions in the credit facility 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 revolving credit loans are available in a
principal amount not to exceed $65 million on a revolving basis until 30 days
prior to the maturity of the revolving credit loans. 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 is available for swing
loans.

      Maturity of Loans. The revolving credit commitments will be reduced
quarterly beginning on February 28, 2002 in amounts to amortize the commitments
until the revolving credit facility matures on January 7, 2008. The term loans
consist of four tranches and amortize over eight years for tranche A term
loans, eight years for tranche A term loans to our subsidiary in Puerto Rico
eight and one-half years for tranche B term loans and nine years for tranche C
term loans.

      Prepayments. Borrowings and commitments under our credit facility are
subject to mandatory prepayment and reduction in an amount equal to

    .  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,

    .  75% of excess cash flow, reduced to 50% with respect to any fiscal
       year if the ratio of total debt to operating cash flow is less than
       6.0:1.0,

    .  100% of the net proceeds of the issuance or incurrence of debt or of
       any sale and lease-back, and

    .  50% of the net proceeds of any issuance of equity securities.
       Voluntary prepayment of the loans will be permitted in whole or in
       part with prior notice.

      The revolving credit loans and the tranche A and tranche A loans to our
subsidiary in Puerto Rico 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

    .  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,

    .  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

    .  thereafter, without premium or penalty, other than funding losses,
       subject to limitations as to minimum amounts.

      Interest Rates. Borrowings under our credit facility bear interest at a
rate per annum of, at the borrowers' option, either

      (a) the higher of (1) the announced prime rate of NationsBank, and (2)
the federal funds rate, plus 0.50%, plus an amount for

    .  the tranche A loans, tranche A loans to our subsidiary in Puerto Rico
       and the revolving credit loans that is 2.00%

    .  the tranche B loans that is 2.50%, and

    .  the tranche C loans that is 2.75% or

                                       67
<PAGE>


      (b) a LIBOR rate plus an amount for

    .  the tranche A loans, tranche A loans to our subsidiary in Puerto Rico
       and the revolving credit loans that is 3.00%,

    .  the tranche B loans that is 3.50%, and

      .the tranche C loans that is 3.75%.

      Based upon Centennial Cellular Operating's leverage ratio after the
delivery of certain financial statements after July 7, 1999, the additional
amount for tranche A loans, tranche A loans to our subsidiary in Puerto Rico
and revolving credit loans may be reduced by up to 1.250% for our loans. The
default rate under our credit facility is 2.00% above the otherwise applicable
rate.

      Fees and Expenses. Our credit facility requires the borrower to pay

    .   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

    .  an annual administrative agent's fee of $150,000 on January 7 of each
       year beginning on January 7, 2000. 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 our credit facility.

      Security. The obligations of Centennial Cellular Operating under our
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 our 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 that 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.

      Representations and Warranties. Our credit facility contains
representations and warranties customarily found in loan agreements for similar
financings.

                                       68
<PAGE>

      Affirmative Covenants.  Our 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. Our 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

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. Our 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,

                                       69
<PAGE>

     .  the failure to or admission in writing of an inability to pay debts
        when such debts become due,

     .  certain events of bankruptcy,

     .  certain judgments or decrees involving more than $10.0 million,

     .  certain ERISA events,

     .  a change of control,

     .  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 financing of the merger, 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 in the original principal amount of $180 million, as well
as 1,626,504 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--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.


                                       70
<PAGE>


      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 new notes like the old notes will be, issued under the indenture
dated December 14, 1998 among Centennial Cellular Operating Co. LLC, as
Centennial Cellular Operating, Centennial Cellular Corp., as a co-obligor, and
Norwest Bank Minnesota, National Association, as trustee, paying agent and
registrar.

      The new notes are the same as the old notes except that the new notes:

     .  will have a new CUSIP number,

     .  will not bear legends restricting their transfer, and

     .  will not contain certain terms providing for an increase in the
        interest rate under the circumstances described in the registration
        rights agreement.

      The following description is a summary of the material provisions of the
indenture. It does not restate that agreement in its entirety. We urge you to
read the indenture because it, and not this description, define your rights as
holders of these notes.

      In this description of notes, the term "Centennial Cellular Operating"
refers to Centennial Cellular Operating Co. LLC and does not include its
subsidiaries and the term "Centennial" refers to Centennial Cellular Corp. and
does not include its subsidiaries. We also use other terms in this section that
are defined under "--Certain Definitions" beginning on page 105.

General Terms of the Notes

      The new notes:

     .  will be our senior subordinated obligations,

     .  will be limited to $370 million aggregate principal amount,

     .  will mature on December 15, 2008, and

     .  will bear interest at the rate 10 3/4% per annum.

      Interest will be paid semi-annually on June 15 and December 15 of each
year, beginning on December 15, 1999 to the holder at the close of business on
the preceding December 1.

      Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

Methods of Receiving Payments on the Notes

      If a holder has given wire transfer instructions to us, we will make all
principal, premium and interest payments on the holder's notes in accordance
with those instructions. All other payments on the notes will be made at our
office or agency within the City and State of New York unless we elect to make
interest payments by check mailed to the holders at their address in the
register of holders.

                                       72
<PAGE>

Ranking

     The payment of the principal of any premium and interest on, the new
notes will be subordinated to the prior payment in full of all of our Senior
Indebtedness. The new notes will be senior subordinated indebtedness of
Centennial Cellular Operating ranking at the same level with all other senior
subordinated indebtedness of Centennial Cellular Operating and senior to all
Subordinated Indebtedness of Centennial Cellular Operating.

     The holders of Senior Indebtedness will be entitled to receive payment in
full of all amounts due in respect of Senior Indebtedness before the holders
of new notes will be entitled to receive any payment with respect to the new
notes in the event of any distribution to our creditors in any bankruptcy,
insolvency or liquidation proceeding with respect to Centennial Cellular
Operating. Holders of new notes may still receive payments made from the trust
described under the caption "--Legal Defeasance and Covenant Defeasance" even
in the event of bankruptcy, insolvency or liquidation.

     Upon any bankruptcy, insolvency or liquidation proceeding, any payment or
distribution of Centennial Cellular Operating's assets of any kind will be
paid by Centennial Cellular Operating or by any receiver, trustee or other
person making such payment or distribution, or by the holders of the new notes
or by the trustee if received by them, directly to the holders of Senior
Indebtedness or their representative or representatives for the payment of the
Senior Indebtedness until all the Senior Indebtedness has been paid in full in
cash.

     Centennial Cellular Operating also may not make any payment in respect of
the new notes if:

     . a payment default on Designated Senior Indebtedness occurs and is
       continuing; or

     . the trustee receives a notice from the agent bank under the credit
       facility or the holders or the representative of any Designated
       Senior Indebtedness indicating that a default has occurred that
       permits the holders of that Indebtedness to accelerate its maturity.

     Payments on the new notes may and will be resumed:

     . in the case of a payment default, upon the date on which such default
       is cured or waived; and

     . in case of a nonpayment default, the earlier of

          (1) the date on which such nonpayment default is cured or waived,

          (2) 179 days after the date on which the applicable notice is
            received, or

          (3) the date on which the trustee receives written notice from the
            agent bank or the representative for such Designated Senior
            Indebtedness, as the case may be, rescinding the applicable
            notice, unless the maturity of any Designated Senior Indebtedness
            has been accelerated.

     No new notice may be delivered as described above unless and until 186
days have elapsed since the effectiveness of the immediately prior notice.

                                      73
<PAGE>


      No event of default that existed or was continuing on the date of
delivery of any such notice to the trustee will be the basis for a subsequent
notice unless such default has been cured or waived for a period of not less
than 90 days.

      As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of Centennial Cellular
Operating, holders of the new notes may recover less than creditors of
Centennial Cellular Operating who are holders of Senior Indebtedness. See "Risk
Factors--Risks Relating to the Notes." Centennial Cellular Operating and its
Restricted Subsidiaries will be subject to financial tests limiting the amount
of additional Indebtedness, including Senior Indebtedness, that Centennial
Cellular Operating and its Restricted Subsidiaries can incur. See "--
Covenants--Limitation on Incurrence of Additional Indebtedness."


Optional Redemption

      General. After December 15, 2003, we may redeem all or a part of the new
notes, upon not less than 30 nor more than 60 days' notice, at the redemption
prices, expressed as percentages of principal amount, set forth below plus any
accrued and unpaid interest, to the applicable redemption date, if redeemed
during the twelve-month period beginning on December 15 of the years indicated
below:

<TABLE>
<CAPTION>
          Year                                        Percentage
          ----                                        ----------
         <S>                                          <C>
         2003........................................  105.375%
         2004........................................  103.583%
         2005........................................  101.792%
</TABLE>

After December 15, 2005, we may redeem all or part of the new notes at 100% of
their principal amount plus any accrued and unpaid interest.

      Upon Equity Offerings. At any time before December 15, 2001, we may on
one or more occasions redeem up to 35% of the aggregate principal amount of new
notes issued under the indenture at a redemption price of 110.750% of the
principal amount of those notes, plus any accrued and unpaid interest to the
redemption date, with the net cash proceeds of one or more Public Equity
Offerings or Strategic Equity Offerings; provided that:

     .  at least 65% of the aggregate principal amount of new notes remains
        outstanding immediately after the occurrence of such redemption,

     .  any redemption because of a Strategic Equity Offering is not in
        connection with or after a Change of Control,

     .  any proceeds received must be contributed to issuer prior to such
        redemption, and

     .  the redemption must occur within 60 days of the date of the closing
        of such Equity Offering.

      Except under the preceding paragraphs, the new notes will not be
redeemable at our option before December 15, 2003.

                                       74
<PAGE>

      Upon a Change of Control. At any time before December 15, 2001, we may
redeem all or part of the new notes upon a Change of Control. Such redemption
must be made within 60 days after a Change of Control at the redemption price
of:

     .  100% of the principal amount, plus

     .  any accrued and unpaid interest to the redemption date, plus

     .  any Applicable Premium.

      Despite the above, the redemption price will not be less than 105.375% of
the principal amount of new notes plus any accrued and unpaid interest to the
redemption date.

      Selection and Notice. If less than all of the new notes are to be
redeemed at any time, the trustee will select the new notes for redemption as
follows:

     .  if the new notes are listed, in compliance with the requirements of
        the principal national securities exchange on which the new notes
        are listed; or

     .  if the new notes are not so listed, on a pro rata basis, by lot or
        by such method as the trustee deems fair and appropriate.

      Despite the above, any redemption relating to a Public Equity Offering or
a Strategic Equity Offering will be on a pro rata basis, or as near as possible
to a pro rata basis.

      No new notes of $1,000 or less shall be redeemed in part. Notices of
redemption will be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each holder of new notes to be redeemed at
its registered address. Notices of redemption may not be conditional.

      If any new note is to be redeemed in part only, the notice of redemption
that relates to that new note shall state the portion of the principal amount
of that note to be redeemed. A new note in principal amount equal to the
unredeemed portion of the original note will be issued in the name of the
holder of the note when the original note is cancelled. Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on new notes or portions of them
called for redemption.

Repurchase at the Option of Holders

      Change of Control. If a Change of Control occurs, each holder of new
notes will have the right to require us to repurchase all or any part, in parts
of $1,000 or an integral multiples of $1,000, of that holder's new notes
pursuant to the Change of Control Offer. In the Change of Control Offer, we
will offer a purchase price in cash equal to 101% of the aggregate principal
amount of new notes repurchased plus any accrued and unpaid interest on the new
notes to the date of purchase. Within 30 days following any Change of Control,
we will mail a notice to each holder describing the transaction or transactions
that constitute the Change of Control and offering to repurchase new notes
within 45 days after the Change of Control, under the procedures required by
the indenture and described in the notice. We will comply with the requirements
of the Exchange Act and any other securities laws and regulations to the extent
such laws and regulations apply to the repurchase of the new notes as a result
of a Change of Control.

                                       75
<PAGE>


      On the date of payment for the redemption describe above, we will, to the
extent allowed by law:

     .  accept for payment all new notes or portions of new notes properly
        tendered pursuant to the Change of Control Offer,

     .  deposit with Norwest Bank Minnesota, National Association, as paying
        agent, an amount equal to the purchase price for all new notes or
        portions of new notes so tendered, and

     .  deliver or cause to be delivered to the trustee the new notes so
        accepted together with an officers' certificate stating the
        aggregate principal amount of new notes or portions of new notes
        being purchased by us.

      Norwest Bank Minnesota, National Association, will promptly mail to each
holder of new notes so tendered the purchase price for new notes tendered, and
will promptly authenticate and mail, or cause to be transferred by book entry,
to each holder a new note equal in principal amount to any unpurchased portion
of new notes surrendered; provided that each new note will be in a principal
amount of $1,000 or an integral multiple thereof.

      Before complying with any of the provisions of this "--Repurchase at the
Option of Holders--Change of Control" covenant, we will either repay all
outstanding Senior Indebtedness or obtain any requisite consents under all
agreements governing outstanding Senior Indebtedness to permit the repurchase
of notes required by this covenant. We will publicly announce the results of
the Change of Control Offer on or as soon as practicable after it is completed.

      The provisions described above that require us to make a Change of
Control Offer following a Change of Control will be applicable regardless of
whether or not any other provisions of the indenture are applicable. Except as
described above with respect to a Change of Control, the indenture does not
contain provisions that permit the holders of the new notes to require that we
repurchase or redeem the new notes in the event of a takeover, recapitalization
or similar transaction.

      Our outstanding Senior Indebtedness currently prohibits us from
purchasing any new notes, and also provides that certain change of control
events with respect to us would constitute a default under the agreements
governing the Senior Indebtedness. Any future credit agreements or other
agreements relating to Senior Indebtedness to which we become a party may
contain similar restrictions and provisions. In the event a Change of Control
when we are prohibited from purchasing new notes, we could seek the consent of
its senior lenders to the purchase of new notes or could attempt to refinance
the borrowings that contain such prohibition. If we do not obtain such consent
or repay such borrowings, we will remain prohibited from purchasing new notes.
In such case, our failure to purchase tendered new notes would be an Event of
Default under the indenture which would, in turn, be a default under our Senior
Indebtedness. In those circumstances, the subordination provisions in the
indenture would likely restrict payments to the holders of new notes.

      The definition of Change of Control includes a phrase relating to the
sale, lease, transfer, conveyance or other disposition of "all or substantially
all" of our assets and our Subsidiaries taken as a whole. Although there is a
limited body of case law interpreting the phrase "substantially all," there is
no precise established definition of the phrase under applicable law.
Accordingly, the ability of a holder of new notes to require us to repurchase
new notes as a result of a sale, lease, transfer, conveyance or other

Sinking Fund

      The new notes will not have the benefit of a sinking fund.

Security

      When the merger was completed, the trustee purchased for the benefit of
the holders of the notes the Pledged Securities in an amount sufficient to
provide for payment of the first three scheduled interest payments due on the
notes. This amount does not include any additional interest that we are
required to pay because the registration statement of which this exchange
offer is a part failed to be declared effective on a timely basis.

      We used about $60 million to purchase Pledged Securities at the time of
the merger. The Pledged Securities are Government Securities maturing on
different dates corresponding to the dates that we have to make the first
three interest payments. The first interest payment of approximately $19
million was made on June 15 out of the Pledged Securities. The next two
interest payments will be funded from the Pledged Securities unless we give
the trustee other funds to make those two interest payments. In that case, the
trustee would be allowed to release the funds in the collateral account that
would have been used to make any of those payments to us.

      Interest earned on the Pledged Securities will be held in a cash
collateral account by the trustee. After we have made the first three interest
payments or, if an internationally recognized independent accounting firm or
investment banking firm determines that the amount of funds in the account
exceed the amount necessary to make the first three interest payments, any
excess in the collateral account will be returned to us.

      The new notes will be secured by a first priority security interest in
the Pledged Securities and the cash collateral account. We may replace the
Government Securities originally pledged as collateral with Marketable U.S.
Securities, if they have a value at least equal to 125.0% of the amount of
unpaid first three interest payments.

      After we have made the next two interest payments any remaining Pledged
Securities will be returned to us. After that time, the new notes will no
longer be secured.

Covenants

      In the indenture, we agreed to some restrictions that limit our and our
Restricted Subsidiaries' ability to:

    .  incur additional debt,

    .  pay dividends, acquire shares of our Capital Stock or that of our
       Restricted Subsidiaries, redeem our Indebtedness or that of our
       Restricted Subsidiaries that is subordinate to the notes or make
       Investments,

    .  restrict our Subsidiaries' abilities to pay dividends to us or other
       Restricted Subsidiaries,

    .  enter into transactions with Affiliates or Related Persons,

    .  issue Guarantees,

    .  sell assets or Capital Stock of Subsidiaries,

    .  create liens,

                                      77
<PAGE>

    .  engage in a merger, sale or consolidation,

    .  enter into new lines of business, and

    .   designate Subsidiaries as Unrestricted Subsidiaries.

      Limitation on Incurrence of Additional Indebtedness. Centennial Cellular
Operating will not, and will not permit any of its Restricted Subsidiaries to
Incur 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 will be deemed to be an Incurrence of Indebtedness.

      Despite the above, Centennial Cellular Operating and any Guarantor may
Incur Indebtedness, including Acquired Indebtedness, and any Restricted
Subsidiary may Incur Acquired Indebtedness if the Centennial Cellular
Operating'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 after December 31, 2000.

      The above will not prohibit the Incurrence of the following:

     (1) Indebtedness of Centennial Cellular Operating, any Guarantor or our
         subsidiary in Puerto Rico under the credit facility not exceeding
         $1.05 billion, reduced by permanent reductions in commitments in
         satisfaction of the Net Cash Proceeds application requirement set
         forth in "--Limitation on Asset Sales and Sales of Subsidiary
         Stock," provided, that the amount of Indebtedness of Centennial de
         Puerto Rico under this clause (1) does not exceed 25% of the amount
         which may be borrowed under this clause (1),

     (2) Indebtedness of Centennial Cellular Operating (a) pursuant to the
         old notes or new notes or (b) existing on December 15, 1998, other

     (3) Indebtedness between Centennial Cellular Operating and any
         Restricted Subsidiary of Centennial Cellular Operating or between
         Restricted Subsidiaries of Centennial Cellular Operating, provided
         that, in the case of Indebtedness of Centennial Cellular Operating,
         such obligations are unsecured and subordinated in all respects to
         the holders' rights under the new notes; provided, further, that
         with respect to any Indebtedness in excess of $250,000, any such
         Indebtedness is made pursuant to an intercompany note in the form
         attached to the indenture; provided, further, that

          .  any disposition, pledge or transfer of any such Indebtedness to a
             Person, other than a disposition, pledge or transfer to
             Centennial Cellular Operating or a Restricted Subsidiary, will be
             deemed to be an Incurrence of such Indebtedness not permitted by
             this clause (3), and

          .  any transaction pursuant to which any Restricted Subsidiary,
             which has Indebtedness owing to Centennial Cellular Operating or
             any other Restricted Subsidiary, ceases to be a Restricted
             Subsidiary will be deemed to be the Incurrence of Indebtedness by
             such Restricted Subsidiary that is not permitted by this clause
             (3),

                                       78

          .  $25 million and

          .  5% of Centennial Cellular Operating's Total Assets; provided that
             in the case of Purchase Money Indebtedness, such Indebtedness
             will not be more than 100% of the cost determined in accordance
             with GAAP to Centennial Cellular Operating or such Restricted
             Subsidiary of the property purchased or leased with the proceeds,

     (5) Indebtedness of Centennial Cellular Operating or any Restricted
         Subsidiary from agreements providing for

          .  indemnification,

          .  adjustment of purchase price, or

          .  similar obligations, or

          .  from related guarantees

       each Incurred in connection with the disposition of any business,
       assets or Restricted Subsidiary of Centennial Cellular Operating to
       the extent they to not result in the obligation to repay borrowed
       money by any person,

     (6) any guarantee by any Restricted Subsidiary of the credit facility
         or any other Indebtedness made in accordance with the provisions of
         "--Limitation on Issuances of Guarantees,"

     (7) Indebtedness incurred by Centennial Cellular Operating or any of
         its Restricted Subsidiaries in connection with the acquisition of a
         new Restricted Subsidiary, the majority of whose revenues for the
         most recent twelve months for which audited or unaudited financial
         statements are available are from a Related Business, or of
         property, businesses or assets which, or Capital Stock of a Person
         all or substantially all of whose assets, are of a type generally
         used in a Related Business; provided, that the principal amount or
         accreted value, as applicable, of such Indebtedness, together with
         any other outstanding Indebtedness incurred under this clause (7),
         does not exceed $40 million in the aggregate at any one time
         outstanding; and provided, further, that the principal amount of
         Indebtedness that may be incurred under this clause (7) and clause
         (11) by any individual Restricted Subsidiary that is not a
         Guarantor will not exceed $25 million in the aggregate,

         ordinary course of business and consistent with industry practices;
         provided that upon the drawing of such letters of credit or the
         incurrence of such Indebtedness, such obligations are reimbursed
         within 30 days following such drawing or incurrence,

     (9) Interest Rate Protection Obligations relating to

          .  Indebtedness of Centennial Cellular Operating or any Restricted
             Subsidiary, which Indebtedness is otherwise permitted to be
             incurred under this covenant, or

          .  Indebtedness for which a lender has provided a commitment in an
             amount reasonably anticipated to be incurred by Centennial

             after such Interest Rate Protection Obligations have been
             incurred; provided, however, that the notional principal

                                       79
<PAGE>

             amount of such Interest Rate Protection Obligations does not

pursuant to clause (b) of the first paragraph of this covenant, (4), (5), (10),

     (5) any agreement, other than those referred to in clause (4), of a

         contained in the security agreements and the credit facility in
         effect on January 7, 1999,

     (7) the indenture and the old notes or new notes,

         course of business to the extent such encumbrance or restriction
         relates to the property underlying the Purchase Money Indebtedness,

     (9) Indebtedness of Restricted Subsidiaries otherwise permitted to be
         incurred under the covenants "--Limitation on Incurrence of
         Additional Indebtedness" and "--Limitation on Liens," which
         encumbrances or restrictions in the aggregate with all such
         previous encumbrances or restrictions do not restrict greater than
         10% of Centennial Cellular Operating's Annual Operating Cash Flow
         on the date of incurrence of the Indebtedness,

    (10) restrictions on cash or other deposits or net worth imposed by

         extent such encumbrance and restriction relates to the activities
         and assets of such joint venture or similar entity and provided
         that the Annual Operating Cash Flow determined as of the date of
         execution of any such joint venture or similar agreement in all
         such joint ventures or similar entities which are subject to such
         encumbrances or restrictions do not exceed 10% of Centennial
         Cellular Operating's Annual Operating Cash Flow on the date of
         execution of such joint venture or similar agreement, or

    (12) customary provisions restricting subletting or assignment of any
         lease entered into the ordinary course of business.

      Limitation on Transactions with Related Persons. Centennial Cellular
Operating will not, and will not permit any of its Restricted Subsidiaries to
engage in an 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 Centennial Cellular Operating or the relevant
    Restricted Subsidiary than those that would have been obtained in a
    comparable transaction by Centennial Cellular Operating or such
    Restricted Subsidiary with an unrelated person and Centennial Cellular
    Operating delivers an officer's certificate to the trustee certifying
    that such Affiliate Transaction complies with this clause (a) and

          (b) with respect to any Affiliate Transaction or series of related
    Affiliate Transactions involving aggregate consideration in excess of
    $10.0 million, Centennial Cellular Operating delivers to the trustee a
    resolution adopted by the majority of the Disinterested Directors
    approving such Affiliate Transaction and set forth in an officer's
    certificate certifying that such Affiliate Transaction complies with
    clause (a) above.

            .  $1 million, or

            .  financing,

            .  underwriting,

            .  placement services, or

               Board of Directors of Centennial Cellular Operating in good
               faith,

     (6) transactions with respect to which Centennial Cellular Operating or
         any of its Restricted Subsidiaries, as the case may be, delivers to
         the trustee a letter from an investment banking firm of national
         standing stating that such transaction is fair to Centennial
         Cellular Operating or such Restricted Subsidiary from a financial
         point of view,

     (7) payments or loans to employees or consultants which are approved by
         a majority of the Board of Directors of Centennial Cellular
         Operating in good faith,

     (8) any agreement as in effect on December 15, 1998, so long as any
         amendment to those agreements is not disadvantageous to the holders
         of the notes in any material respect, or any transaction
         contemplated by any of those agreements,

                                       88
<PAGE>


     (9) the existence of, or the performance by Centennial Cellular
         Operating or any of its Restricted Subsidiaries of its obligations
         under the terms of, the Recapitalization Documents, including any
         registration rights agreement or purchase agreement related
         thereto, to which it is a party on December 15, 1998 and any
         similar agreements which it may enter into after December 15, 1998;
         provided, however, that the existence of, or the performance by
         Centennial Cellular Operating 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
         December 15, 1998 will only be permitted by this clause,

    (10) to the extent that the terms of any amendment or new agreement are
         not otherwise disadvantageous to the holders of the new notes in
         any material respect,

    (11) the payment of all fees, expenses, bonuses and awards related to
         the Recapitalization including fees to Welsh Carson and Blackstone,

         Cellular Operating and any other Person with which Centennial
         Cellular Operating is required or permitted to file a consolidated
         tax return or with which Centennial Cellular Operating is or could
         be part of a consolidated group for tax purposes, which payments
         are not in excess of the tax liabilities attributable solely to
         Centennial Cellular Operating and its Restricted Subsidiaries as a
         consolidated group.

      Limitation on Issuances of Guarantees. (a) Centennial Cellular Operating
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 Centennial Cellular Operating or any
Restricted Subsidiary, other than under the credit facility, unless such
Restricted Subsidiary simultaneously executes and delivers a supplemental
indenture to the indenture and becomes a Guarantor except that

    (A) such guarantee need not be secured unless required under "--
        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 will be senior to such
        Restricted Subsidiary's Guarantee of the notes to the same extent as
        such Senior Indebtedness is senior to the new notes, and

    (C) if such Indebtedness is by its terms expressly subordinated to the
        new notes, any such assumption, guarantee or other liability of such
        Restricted Subsidiary with respect to such Indebtedness will 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) Despite the above, any Guarantee by a Restricted Subsidiary of the
new notes will provide by its terms that it and all Liens securing the same
will be automatically and unconditionally released and discharged upon

    (1) any sale, exchange or transfer, to any person not an Affiliate of
        Centennial Cellular Operating, of all of Centennial Cellular
        Operating'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

                                       89
<PAGE>


       from any guarantees, by it or other Indebtedness of Centennial
       Cellular Operating or any Restricted Subsidiaries, or

    (2) the release by the holders of the Indebtedness of Centennial
        Cellular Operating 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 Centennial Cellular Operating 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. Centennial
Cellular Operating will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale, unless

    (1) 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 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 Centennial Cellular Operating and its Restricted Subsidiaries
        will not be required to receive any cash in connection with the
        transfer or contribution of assets to a joint venture, 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
        December 15, 1998 and permitted to have been Incurred under the
        covenant "--Limitation on Incurrence of Additional Indebtedness",
        including that in the case of a revolver or similar arrangement,
        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, and

    (2) the board of directors of Centennial Cellular Operating determines
        in good faith that Centennial Cellular Operating or such Restricted
        Subsidiary, as applicable, would receive fair market value in
        consideration of such Asset Sale.

      Despite the above:

    (1) Centennial Cellular Operating and its Restricted Subsidiaries may,
        in the ordinary course of business dispose of assets acquired and
        held for resale in the ordinary course of business,


                                      90
<PAGE>


    (2) Centennial Cellular Operating and its Restricted Subsidiaries may
        dispose of assets under and in accordance with the "--Limitation on
        Mergers, Sales or Consolidations" covenant,

    (3) Centennial Cellular Operating and its Restricted Subsidiaries may
        dispose of damaged, worn out or other obsolete property in the
        ordinary course of business so long as it is no longer necessary for
        the proper conduct of the business of Centennial Cellular Operating
        or such Restricted Subsidiary, as applicable,

    (4) Centennial Cellular Operating and its Restricted Subsidiaries may
        dispose of assets to Centennial Cellular Operating or any of its
        Restricted Subsidiaries in accordance with the terms of the
        indenture, and

    (5) Centennial Cellular Operating and its Restricted Subsidiaries may,
        in the ordinary course of business 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 Centennial
        Cellular Operating on December 14, 1998 or a Related Business;
        provided that such Person will initially be designated a Restricted
        Subsidiary if such Person becomes a Subsidiary of Centennial
        Cellular Operating 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

     .  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
        Centennial Cellular Operating or such Restricted Subsidiary of the
        proposed transaction,

     .  a majority of the Disinterested Directors of the board of
        directors of Centennial Cellular Operating approve a resolution of
        the board of directors that such exchange is fair to Centennial
        Cellular Operating or such Restricted Subsidiary, as the case may
        be,

     .  any cash or Cash Equivalents received pursuant to any such
        exchange will be applied in the manner applicable to Net Cash
        Proceeds from an Asset Sale as set forth under "--Repurchase at
        the Option of Holders--Asset Sales."

     .  any Capital Stock of a Person received in an Asset Sale pursuant
        to this clause (5) will be owned directly by Centennial Cellular
        Operating or a Restricted Subsidiary and, when combined with the
        Capital Stock of such Person already owned by Centennial Cellular
        Operating and its Restricted Subsidiaries, will 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.

      Within one year after the receipt of any Net Cash Proceeds from an Asset
Sale, we or any Restricted Subsidiary may apply such Net Cash Proceeds, at its
option:

     .  to repay or repurchase our or any Restricted Subsidiary's Senior
        Indebtedness; or

     .  to acquire assets of a Related Business, or the Capital Stock of a
        Person, all or substantially all of whose assets and property are
        used in a Related Business.

                                       91
<PAGE>


      Any Net Cash Proceeds from Asset Sales that are not applied or invested
as provided in the preceding paragraph will constitute "Excess Proceeds".
Within one year after an Asset Sale when the aggregate amount of Excess
Proceeds exceeds $15 million, we will be required to make an Asset Offer Sale.
The offer price in any Asset Sale Offer will be equal to 100% of principal
amount plus any accrued and unpaid interest to the date of purchase, and will
be payable in cash. If the aggregate principal amount of new notes tendered
into such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee
will select the new notes to be purchased on a pro rata basis.

      Limitation on Liens. Centennial Cellular Operating 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 to any such Lien by any Restricted Subsidiary upon any
property or assets of Centennial Cellular Operating or any Restricted
Subsidiary, or any income or profits of Centennial Cellular Operating or any
Restricted Subsidiary, unless the new notes are directly secured equally and
ratably with or, in the case of Subordinated Indebtedness, prior or senior to
the new notes, with the same relative priority as the new notes will 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 liability 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 of any such Indebtedness described in clause (A), so
        long as the aggregate principal amount of Indebtedness represented
        by such Indebtedness, or, if such Indebtedness provides for an
        amount less than the principal amount of such Indebtedness to be due
        and payable upon a declaration of acceleration of the maturity of
        such Indebtedness, the original issue price of such Indebtedness
        plus any accreted value attributable of such Indebtedness 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 Centennial Cellular Operating 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 Centennial Cellular Operating or its
        Restricted Subsidiaries.

      Despite the above, any Lien securing the new notes granted under this
covenant will 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

                                       92

      In the event that Centennial merges or consolidates with or into
Centennial Cellular Operating, the provisions of the first paragraph of this
Section are also required to be satisfied.

      Upon any transaction in accordance with the above, the successor
corporation formed by such consolidation or into which Centennial Cellular
Operating or Centennial, as the case may be, is merged or to which such
transfer is made, will succeed to, and be substituted for, and may exercise
every right and power of, Centennial Cellular Operating or Centennial, as the
case may be, under the indenture with the same effect as if the successor
entity had been named in the indenture as Centennial Cellular Operating or
Centennial, as the case may be, and Centennial Cellular Operating 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 will as of the last balance sheet available,
revenues, or Annual Operating Cash Flow of Centennial Cellular Operating or
Centennial, as the case may be, as of the last twelve month period for which
financial statements are available, will be released from the obligations under
the new notes and the indenture.

      Limitation on Lines of Business. Neither Centennial Cellular Operating
nor any of its Restricted Subsidiaries will directly or indirectly engage in
any line or lines of business activity other than a Related Business.

      Limitation on Senior Subordinated Indebtedness. We will not, and will not
permit or cause any Guarantor to, incur any Indebtedness that is subordinate in
right of payment to any of our Indebtedness or such Guarantor, as the case may
be, unless such Indebtedness is also equal in right of payment with the new
notes or the Guarantee of such Guarantor or subordinated in right of payment to
the new 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. All of our subsidiaries are
currently Restricted Subsidiaries. Centennial Cellular Operating may make
designate a Subsidiary as an Unrestricted Subsidiary only if:

    (a) no Default shall have occurred and be continuing at the time of or
        after giving effect to such designation,

    (b) Centennial Cellular Operating would be permitted to make an
        Investment at the time of Designation, assuming the effectiveness of
        such designation, under "--Limitation on Restricted Payments" above
        the greater of the net book value or fair market value of our
        interest in that Subsidiary,

    (c) such Unrestricted Subsidiary does not own any Capital Stock in any
        Restricted Subsidiary of Centennial Cellular Operating which is not
        simultaneously being designated an Unrestricted Subsidiary,

    (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 new notes, and

    (e) such Unrestricted Subsidiary is not a party to any agreement,
        contract, arrangement or understanding at such time with Centennial
        Cellular Operating or any Restricted Subsidiary unless the terms of
        any such

      .  agreement,

                                       96
<PAGE>


      .  contract,

      .  arrangement, or

      .  understanding

are no less favorable to Centennial Cellular Operating or such Restricted
Subsidiary than those that might be obtained at the time from persons who are
not Affiliates of Centennial Cellular Operating or, in the event such condition
is not satisfied, the value of such agreement, contract, arrangement or
understanding to such Unrestricted Subsidiary will be considered a Restricted
Payment.

      In the event of any such designation, Centennial Cellular Operating will
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.

      Centennial Cellular Operating will not and will 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 will 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 above, the designation of a Subsidiary of Centennial
Cellular Operating as an Unrestricted Subsidiary will be deemed to be the
designation of all of the Subsidiaries of such Subsidiary as Unrestricted
Subsidiaries.

      Centennial Cellular Operating may make a revoke of the designation of any
Subsidiary as an Unrestricted Subsidiary if:

    (a) no Default will 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 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, Centennial Cellular
        Operating could incur $1.00 of additional Indebtedness, other than
        Permitted Indebtedness, under 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 Centennial Cellular Operating delivered to the trustee

Operating is subject to the reporting requirement of the Exchange Act, so long
as any new notes are outstanding, Centennial Cellular Operating will, to the

     .  if filing such documents by Centennial Cellular Operating 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 Centennial Cellular Operating's cost.

      So long as any of the new notes remain outstanding, Centennial Cellular
Operating will make new notes available to any prospective purchaser of new
notes or beneficial owner of notes in connection with any sale of the
information required by the Securities Act, until such time as Centennial
Cellular Operating 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 of the new notes have disposed of such new notes
pursuant to an effective registration statement under the Securities Act.
Centennial Cellular Operating will be deemed to have satisfied the requirements
set forth above if

     .  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,

     .  Centennial Cellular Operating is not required to file such reports

our subordinated debt in a manner adverse to the holders of new notes.

                                       98

      Additional Covenants. The indenture also contains covenants with respect

     .  payment of principal, premium and interest,

     .  maintenance of an office or agency in The City of New York,

     .  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 us to pay any installment of interest on the notes
        when it becomes due and payable and the continuance of such failure
        for 30 days,

    (2) the failure by us to pay all or any part of the principal, or any
        premium on the notes when it becomes due and payable at

      .  maturity,

      .  redemption,

      .  by acceleration or

      .  otherwise, including, without limitation, payment of the Change of
         Control Purchase Price or the Asset Sale Offer Price,

    (3) the failure by us to observe or perform any other covenant or
        agreement contained in the notes or the indenture and, subject to
        certain exceptions, the continuance of such failure for a period of
        30 days after written notice is given to Centennial Cellular
        Operating by the trustee or to Centennial Cellular Operating and the
        trustee by the holders of at least 25% in aggregate principal amount
        of the notes outstanding,

    (4) certain events of bankruptcy, insolvency, or liquidation affecting
        us or any of our Significant Restricted Subsidiaries,


    (5) any Guarantee of a Significant Restricted Subsidiary will for any
        reason cease to be in full force and effect and enforceable in
        accordance with its terms or Centennial will for any reason cease to
        be, or will for any reason be asserted in writing not to be, a
        co-obligor pursuant to the notes,

    (6) one or more defaults in any Indebtedness for money borrowed by us or
        any of our Restricted Subsidiaries, or the payment of which is
        guaranteed by us or any of our Restricted Subsidiaries or which
        default

      .  results from the failure to pay Indebtedness at its final maturity
         date or

      .  results in the acceleration of such Indebtedness before its
         express maturity

                                       99
<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

    (7) final unsatisfied judgments, orders or decrees in excess of
        $20,000,000, exclusive of any portion of any such payment covered by
        insurance, at any one time against us or any of our 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 clause (4) above relating to us or any Significant
Restricted Subsidiary, then in every such case, unless the principal of all of
the notes has 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 Centennial Cellular Operating, and to the
trustee if given by holders, 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 applicable, determined as
set forth below, including in each case accrued interest on the notes 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 clause (4) with respect to us or any
Significant Restricted Subsidiary, any such acceleration will not be effective
until the earlier to occur of

     .  five business days following delivery of a written notice of such
        acceleration of the notes to the agent under the credit facility and

     .  the acceleration of any Indebtedness under the credit facility. If
        an Event of Default specified in clause (4) above relating to us or
        any Restricted Subsidiary occurs, all principal and accrued interest
        on the notes 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 any premium 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.

                                      100
<PAGE>


      No holder of any of the new notes has any right to institute any
proceedings with respect to the indenture or any remedy under the indenture,
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

     .  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 new note for the enforcement of the payment of the principal of, any
premium or interest on such note on or after the respective due dates expressed
in such note.

      We must notify the trustee within five business days after any Default.
We must 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 us or any Guarantor 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

      Centennial Cellular Operating may, at its option and at any time, elect
to have completely defease the new notes. Such complete defeasance means that
we, any such Guarantor and any other obligor under the indenture will be deemed
to have paid and discharged the entire indebtedness represented, and the
indenture will cease to be of further effect as to all outstanding notes,
except as to

    (1) rights of Holders to receive payments on such notes when such
        payments are due from the trust funds,

    (2) our 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 Centennial Cellular Operating's obligations in connection with
        the indenture, and

    (4) the legal defeasance provisions of the indenture.

      In addition, Centennial Cellular Operating may, at its option and at any
time, elect to defease a covenant under the indenture and after that defeasance
any omission to comply with such obligations will not constitute a Default or
Event of Default with respect to the notes. In the event a covenant is
defeased, certain events will no longer constitute an Event of Default with
respect to the new notes.

                                      101
<PAGE>


      In order to exercise a defeasance,

    (1) Centennial Cellular Operating 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, any premium and interest on such notes on the
        stated date for payment or on any redemption date on such notes, and
        the holders of notes must have a valid, perfected, exclusive
        security interest in such trust,

    (2) in the case of a complete, Centennial Cellular Operating will have
        delivered to the trustee an opinion of counsel in the United States
        reasonably acceptable to the trustee confirming that the holders of
        new notes will not recognize any gain or loss for Federal income tax
        purposes from the defeasance and will still be subject to the same
        amount of Federal income tax as if the defeasance had not occurred,

No Personal Liability of Partners, Stockholders, Officers, Directors

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 to the extent
permitted by law.

Concerning the Trustee

      The indenture contains certain limitations on the rights of the trustee,
should it become a creditor of Centennial or Centennial Cellular Operating, 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. 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 and will be
deposited with, or on behalf of, the DTC, 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
your interest in old notes is represented by the initial global note and you
fail to tender in the exchange offer, we may issue and deliver to you a
separate certificate representing your 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. Centennial Cellular Operating 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 Centennial Cellular Operating that: 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 the Exchange Act. DTC was created to hold
securities for its participants and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entry
changes in accounts of its participants, 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,

                                      126
<PAGE>


dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

      Under procedures established by DTC,

          (1) 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

          (2) 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 new 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 by the global note, 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. 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 of the global
notes. Neither Centennial Cellular Operating, 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.

      Centennial Cellular Operating expects that DTC or its nominee, upon
receipt of any payment of principal premium 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. Centennial Cellular
Operating 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 Centennial
Cellular Operating 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
Centennial

                                      127
<PAGE>

Cellular Operating 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 Centennial Cellular Operating 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. See "--Certificated
Notes."

      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 Centennial Cellular Operating, 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.

      Certificated Notes. An entire global note may be exchanged for definitive
notes in registered, certificated form without interest coupons if:

    (1) DTC (x) notifies the company that it is unwilling or unable to
        continue as depositary for the global notes and Centennial Cellular
        Operating then fails to appoint a successor depositary within 90
        days or (y), has ceased to be a clearing agency registered under the
        Exchange Act,

    (2) Centennial Cellular Operating, at its option, notifies the trustee
        in writing that it elects to cause the issuance of certificated
        notes, or

    (3) there will have occurred and be continuing a Default or an Event of
        Default with respect to notes. In any such case, Centennial Cellular
        Operating will notify the trustee in writing that, upon surrender by
        the direct and indirect participants of their interest in such
        global note, certificated notes will be issued to each person that
        such direct and indirect participants and the DTC identify as being
        the beneficial owner of the related notes.

      Beneficial interests in global notes held by any direct or indirect
participant may be exchanged for certificated notes upon request to DTC, by a
direct participant, for itself or on behalf of an indirect participant, to the
trustee in accordance with customary DTC procedures. Certificated notes
delivered in exchange for any beneficial interest in any global note will be
registered in the names, and issued in any approved denominations, requested by
DTC on behalf of such direct or indirect participant, in accordance with DTC's
customary procedures.

                   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 of this
prospectus. 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 your 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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

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

                                      II-1
<PAGE>

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).

Item 22. Undertakings

      (a) The undersigned registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being
    made, a post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
      Securities Act;

        (ii) To reflect in the prospectus any facts or events arising
      after the effective date of the registration statement (or the most
      recent post-effective amendment thereof) which, individually or in
      the aggregate, represent a fundamental change in the information set
      forth in the registration statement;

        (iii) To include any material information with respect to the plan
      of distribution not previously disclosed in the registration
      statement or any material change in such information in the
      registration statement;

      (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be
    a new registration statement relating to the securities offered therein,
    and the offering of such securities at the time shall be deemed to be
    initial bona fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

      (b) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

      (c) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.



      (d) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first

                                      II-4
<PAGE>

class mail or other equally prompt means. This includes information contained
in documents filed subsequent to the effective date of the registration
statement through the date of responding to the request.

      (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                      II-5

  The undersigned acknowledges receipt of the Prospectus dated    , 1999 (the
"Prospectus"), of Centennial Cellular Corp., a Delaware corporation
("Centennial"), and Centennial Cellular Operating Co. LLC, a Delaware limited
liability company (together with Centennial, the "Issuers"), and this Letter
of Transmittal (the "Letter of Transmittal"), which together with the
Prospectus constitutes the Issuers' offer (the "Exchange Offer") to exchange
$1,000 principal amount of their 10 3/4% Senior Subordinated Notes due 2008,
Series B (the "New Notes"), for each $1,000 principal amount of their
outstanding 10 3/4% Senior Subordinated Notes due 2008, Series A (the "Old
Notes"). Recipients of the Prospectus should read the requirements described
in such Prospectus with respect to eligibility to participate in the Exchange
Offer. Capitalized terms used but not defined herein have the meaning given to
them in the Prospectus.

  The undersigned hereby tenders the Old Notes described under "Description of
Old Notes" below pursuant to the terms and conditions described in the
Prospectus and this Letter of Transmittal. The undersigned is the registered
owner of all the Old Notes.

  This Letter of Transmittal is to be used by a holder of Old Notes (i) if
certificates representing Old Notes are to be forwarded herewith, (ii) if
delivery of Old Notes is to be made by book-entry transfer to the Exchange
Agent's account at The Depository Trust Company ("DTC"), pursuant to the
procedures set forth in the section of the Prospectus entitled "The Exchange
Offer," and an Agent's Message (as defined herein) is not delivered or (iii)
if a tender is made pursuant to the guaranteed delivery procedures in the
section of the Prospectus entitled "The Exchange Offer."

  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact such registered holder of Old Notes promptly and
instruct such registered holder of Old Notes to tender on behalf of the
beneficial owner. If such beneficial owner wishes to tender on its own behalf,
such beneficial owner must, prior to completing and executing this Letter of
Transmittal and delivering its Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or
obtain a properly completed bond power from the registered holder of Old
Notes. The transfer of record ownership may take considerable time.

  In order to properly complete this Letter of Transmittal, a holder of Old
Notes must (i) complete the box entitled "Description of Old Notes," (ii) if
appropriate, check and complete the boxes relating to book-entry transfer,
guaranteed delivery, Special Issuance Instructions and Special Delivery
Instructions, (iii) sign the Letter of Transmittal by completing the box
entitled "Sign Here" and (iv) complete the Substitute Form W-9. Each holder of
Old Notes should carefully read the detailed instructions below prior to
completing the Letter of Transmittal.

  Holders of Old Notes who desire to tender their Old Notes for exchange and
(i) whose Old Notes are not immediately available or (ii) who cannot deliver
their Old Notes, this Letter of Transmittal and all other documents required
hereby to the Exchange Agent on or prior to the Expiration Date, must tender
the Old Notes pursuant to the guaranteed delivery procedures set forth in the
section of the Prospectus entitled "The Exchange Offer." See Instruction 2.

  Holders of Old Notes who wish to tender their Old Notes for exchange must
complete columns (1) through (3) in the box below entitled "Description of Old
Notes," complete the boxes entitled and sign the box below entitled "Sign
Here." If only those columns are completed, such holder of Old Notes will have
tendered for exchange all Old Notes listed in column (3) below. If the holder
of Old Notes wishes to tender for exchange less than all of such Old Notes,
column (4) must be completed in full. In such case, such holder of Old Notes
should refer to Instruction 5.

Ladies and Gentlemen:

  By executing this Letter of Transmittal and subject to and effective upon
acceptance for exchange of the Old Notes tendered for exchange herewith, the
undersigned will have irrevocably sold, assigned, transferred and exchanged,
to the Issuers, all right, title and interest in, to and under all of the Old
Notes tendered for exchange hereby, and hereby will have appointed the
Exchange Agent as the true and lawful agent and attorney-in-fact (with full
knowledge that the Exchange Agent also acts as agent of the Issuers) of such
holder of Old Notes with respect to such Old Notes, with full power of
substitution to (i) deliver certificates representing such Old Notes, or
transfer ownership of such Old Notes on the account books maintained by DTC
(together, in any such case, with all accompanying evidences of transfer and
authenticity), to the Issuers, (ii) present and deliver such Old Notes for
transfer on the books of the Issuers and (iii) receive all benefits and
otherwise exercise all rights and incidents of beneficial ownership with
respect to such Old Notes, in accordance with the terms of the Exchange Offer.
The power of attorney granted in this paragraph shall be deemed to be
irrevocable and complete with an interest.

  The undersigned hereby represents and warrants that (i) the undersigned is
the owner; (ii) the undersigned has full power and authority to tender,
exchange, assign and transfer the Old Notes and (iii) that when such Old Notes
are accepted for exchange by the Issuers, the Issuers will acquire good and
marketable title thereto, free and clear of all liens, restrictions, charges

Notes acquired by such person and cannot rely on the position of the staff of
the Commission set forth in certain no-action letters, and (iv) neither the
undersigned nor any beneficial owner is an "affiliate," as defined under Rule
405 under the Securities Act, of the Issuers. If the undersigned is a broker-

the requirements of the Securities Act in connection with any resale of such
New Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the

accepted for exchange, and to have exchanged, validly tendered Old Notes, if,
as and when the Issuers give oral or written notice thereof to the Exchange
Agent. Tenders of Old Notes for exchange may be withdrawn at any time prior to
5:00 p.m., New York City time, on the Expiration Date. See "The Exchange

Expiration Date.

  The undersigned acknowledges that the Issuers' acceptance of Old Notes

in the section of the Prospectus entitled "The Exchange Offer" and in the
instructions hereto will constitute a binding agreement among the undersigned
and the Issuers upon the terms and subject to the conditions of the Exchange
Offer.

"Special Delivery Instructions" to transfer any Old Notes from the name of the
holder thereof if the Issuers do not accept for exchange any of the Old Notes
so tendered for exchange or if such transfer would not be in compliance with
any transfer restrictions applicable to such Old Notes.

to be conferred shall survive the death, incapacity, or dissolution of the
undersigned, and any obligation of the undersigned hereunder shall be binding

THE HOLDER. EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED
MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. INSTEAD
OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND
DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NEITHER THIS LETTER OF TRANSMITTAL NOR ANY OLD NOTES SHOULD BE SENT TO THE
ISSUERS. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH
HOLDERS.

  No alternative, conditional or contingent tenders will be accepted. All
tendering holders of Old Notes, by execution of this Letter of Transmittal (or
facsimile hereof, if applicable), waive any right to receive notice of the
acceptance of their Old Notes for exchange.

  3. Inadequate Space. If the space provided in the box entitled "Description
of Old Notes" above is inadequate, the certificate numbers and principal
amounts of the Old Notes being tendered should be listed on a separate signed
schedule affixed hereto.

  4. Withdrawals. A tender of Old Notes may be withdrawn at any time prior to
5:00 p.m., New York City time, on the Expiration Date by written notice of
withdrawal to the Exchange Agent at the address set forth on the cover of this
Letter of Transmittal via telegram, telex, facsimile transmission or letter.
To be effective, a notice of withdrawal of Old Notes must (i) specify the name
of the person who tendered the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number
or numbers and aggregate principal amount of such Old Notes) or, in the case
of Old Notes transferred by book-entry transfers, the name and number of the
account at DTC to be credited, (iii) be signed by the holder of Old Notes in
the same manner as the original signature on the Letter of Transmittal by
which such Old Notes were tendered (including any required signature
guarantees) and (iv) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. All questions as to the
validity, form and eligibility (including time of receipt) of such notices
will be determined by the Issuers, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will thereafter be deemed
not validly tendered for purposes of the Exchange Offer and no New Notes will
be issued with respect thereto unless the Old Notes so withdrawn are validly
retendered. Properly withdrawn Old Notes may be retendered by following one of
the procedures described in the section of the Prospectus entitled "The
Exchange Offer -- Procedures for Tendering" at any time prior to 5:00 p.m.,
New York City time, on the Expiration Date.

  5. Partial Tenders. Tenders of Old Notes will be accepted only in integral
multiples of $1,000 principal amount. If a tender for exchange is to be made
with respect to less than the entire principal amount of an Old Notes, fill in
the principal amount of Old Notes which are tendered for exchange in column
(4) of the box entitled "Description of Old Notes," as more fully described in
the footnotes thereto. In case of a partial tender for exchange, a new
certificate, in fully registered form, for the remainder of the principal
amount of the Old Notes, will be sent to the holders of Old Notes unless
otherwise indicated in the appropriate box on this Letter of Transmittal as
promptly as practicable after the expiration or termination of the Exchange
Offer.

  6. Signatures on this Letter of Transmittal, Assignment and Endorsements.

Transmittal must correspond with the name(s) as written on the face of the Old
Notes without alteration, enlargement or any change whatsoever.

listed and transmitted hereby, no endorsements of Old Notes or bond powers are

Notes. Signatures on such Old Notes or bond powers must be guaranteed by an
Eligible Institution (unless signed by an Eligible Institution).

  7. Transfer Taxes. Except as set forth in this Instruction 7, the Issuers
will pay all transfer taxes, if any, applicable to the exchange of Old Notes
pursuant to the Exchange Offer. If, however, a transfer tax is imposed for any
reason other than the exchange of the Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemptions
therefrom is not submitted with this Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.

  8. Special Issuance and Delivery Instructions. If the New Notes are to be
issued, or if any Old Notes not tendered for exchange are to be issued or sent
to someone other than the holder of Old Notes or to an address other than that

completed. Holders of Old Notes tendering Old Notes by book-entry transfer may
request that Old Notes not accepted be credited to such account maintained at

  9. Irregularities. All questions as to the validity, form, eligibility
(including time of receipt), compliance with conditions, acceptance and
withdrawal of tendered Old Notes will be determined by the Issuers in its sole
discretion, which determination will be final and binding. The Issuers reserve
the absolute right to reject any and all Old Notes not properly tendered or
any Old Notes the Issuers' acceptance of which would, in the opinion of
counsel for the Issuers, be unlawful. The Issuers also reserve the right to
waive any defects or irregularities as to particular Old Notes. The Issuers'
interpretation of the terms and conditions of the Exchange Offer (including
the instructions in the Letter of Transmittal) will be final and binding on
all parties. Unless waived, any defects or irregularities in connection with
tenders of Old Notes must be cured within such time as the Issuers shall
determine. Although the Issuers intend to notify holders of defects or
irregularities with respect to tenders of Old Notes, neither the Issuers, the
Exchange Agent nor any other person shall incur any liability for failure to
give such notification. Tenders of Old Notes will not be deemed to have been
made until such defects or irregularities have been cured or waived. Any Old
Notes received by the Exchange Agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering holders, unless otherwise
provided in this Letter of Transmittal, as soon as practicable following the
Expiration Date.

  10. Waiver of Conditions. The Issuers reserve the right to waive, amend or
modify certain of the specified conditions as described under "The Exchange
Offer -- Conditions" in the Prospectus in the case of any Old Notes tendered
in the Issuers' reasonable discretion (except as otherwise provided in the

                           IMPORTANT TAX INFORMATION

  Under current federal income tax law, a holder of Old Notes whose tendered
Old Notes are accepted for exchange may be subject to backup withholding
unless the holder provides the Issuers (as payor), through the Exchange Agent,
with either (i) such holder's correct taxpayer identification number ("TIN")
on Substitute Form W-9 attached hereto, certifying that the TIN provided on
Substitute Form W-9 is correct (or that such holder of Old Notes is awaiting a
TIN) and that (A) the holder of Old Notes has not been notified by the
Internal Revenue Service that he or she is subject to backup withholding as a
result of a failure to report all interest or dividends or (B) the Internal
Revenue Service has notified the holder of Old Notes that he or she is no
longer subject to backup withholding; or (ii) an adequate basis for exemption
from backup withholding. If such holder of Old Notes is an individual, the TIN
is such holder's social security number. If the Exchange Agent is not provided
with the correct taxpayer identification number, the holder of Old Notes may
be subject to certain penalties imposed by the Internal Revenue Service.

  Certain holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt holders of Old Notes should indicate their
exempt status on Substitute Form W-9. A foreign individual may qualify as an
exempt recipient by submitting to the Exchange Agent a properly completed
Internal Revenue Service Form W-8 (which the Exchange Agent will provide upon
request) signed under penalty of perjury, attesting to the holder's exempt
status. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 (the "Guidelines") for additional
instructions.

  If backup withholding applies, the Issuers are required to withhold 31% of
any payment made to the holder of Old Notes or other payee. Backup withholding
is not an additional federal income tax. Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.

  The holder of Old Notes is required to give the Exchange Agent the TIN
(e.g., social security number or employer identification number) of the record
owner of the Old Notes. If the Old Notes are held in more than one name or are
not held in the name of the actual owner, consult the enclosed Guidelines for
additional guidance regarding which number to report.

          WHEREAS, in connection therewith, on January 7, 1999 the Company and
each of the Stockholders other than the Guayacan Purchasers executed and
delivered a Stockholders Agreement (the "Original Stockholders Agreement")
setting forth certain arrangements among themselves with respect to the
governance of the Company and the other matters set forth therein;

          WHEREAS, upon the merger of CCW with and into the Company on January
7, 1999, the Company succeeded to all the rights and obligations of CCW under
the Purchase Agreement and the Original Stockholders Agreement; and

          WHEREAS, the Company and the Stockholders desire to amend and restate
such Original Stockholders Agreement in its entirety, as more particularly set
forth herein;

          NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties hereto hereby agree as
follows:

          SECTION 1.  Voting Agreement.
                      ----------------
<PAGE>

          (a)    From and after the Closing Date (as defined in the Purchase
Agreement), at each annual or special stockholders meeting called for the
election of directors, and whenever the stockholders of the Company act by
written consent with respect to the election of directors, each Stockholder
agrees to vote or otherwise give such Stockholder's consent in respect of all
shares of capital stock of the Company (whether now or hereafter acquired) owned
by such Stockholder, and take all other appropriate action, and the Company
shall take all necessary and desirable actions within its control, in order to
cause:

          (i)    the authorized number of directors on the Board of Directors of
     the Company (the "Board") to be established at nine;

          (ii)   the election to the Board of:

                 a)  three directors designated by the holders of a majority of
          the Common Stock then held by all WCAS Purchasers (the "WCAS
          Designees") so long as the WCAS Purchasers own (in the aggregate) not
          less than 25% of the shares of Common Stock owned by them on the date
          hereof, which directors will initially be Thomas E. McInerney, Anthony
          J. de Nicola and Rudolph E. Rupert;

                 b)  two directors designated by the holders of a majority of
          the Common Stock then held by all Blackstone Purchasers (the
          "Blackstone Designees") so long as the Blackstone Purchasers own (in
          the aggregate) not less than 25% of the shares of Common Stock owned
          by them on the date hereof, which directors will initially be Mark T.
          Gallogly and Lawrence H. Guffey; and

                 c)  the Chief Executive Officer and the Chief Operation Officer
          of the Company (initially Michael J. Small and Rudy J. Graf,
          respectively);

     all of which persons shall hold office, subject to their earlier removal in
     accordance with clause (iii) below, the By-laws of the Company and
     applicable corporate law, until their respective successors shall have been
     elected and shall have qualified;

          (iii)  the removal from the Board (with or without cause) of any
     director elected in accordance with subpart a) or b) of clause (ii) above
     upon the written request of the Stockholders that designated such director;

          (iv)   upon any vacancy in the Board as a result of any individual
     designated as provided in clause (ii) above ceasing to be a member of the
     Board, whether by resignation or otherwise, the election to the Board as
     promptly as possible of an individual designated by the Stockholders that
     designated such individual (or, in the case of a director specified in
     subpart c) of clause (ii) above, an individual meeting such
     qualifications); and


                                       2
<PAGE>

          (v)    their respective designees to the Board of Directors of the
     Company to elect Thomas E. McInerney (or such other person as may be
     designated by the WCAS Purchasers) as Chairman of the Board of Directors.

          (b)    The two directors not designated pursuant to clause (ii) of
paragraph (a) above shall be directors (the "Outside Directors") that shall be
elected by the stockholders of the Company. In any such election, the
Stockholders shall vote their shares only for persons that (x) are not employees
or officers of (i) the Company or any of its subsidiaries or (ii) the
Stockholders or their respective stockholders, members or partners and (y)
otherwise qualify as "independent directors" under the rules applicable to
Nasdaq National Market companies as in effect on the date hereof and satisfy any
other requirements under applicable law or the rules of any exchange or
quotation system on which the Common Stock is then listed or traded.

          (c)    Each Stockholder agrees to use its best efforts to cause its
designees to the Board to vote or otherwise give such Director's consent to the
creation and maintenance of:

          (i)    a Compensation Committee of the Board consisting of three
     directors, two of whom shall be WCAS Designees, if any then exist, and the
     third of whom shall be a Blackstone Designee, if any then exist, which
     Compensation Committee shall approve all grants of stock options to
     employees of the Company, all increases in compensation of officers of the
     Company, all annual bonuses granted to officers of the Company and all
     other employee benefits (including, without limitation, vacation policy,
     benefit plans, company automobiles and insurance) granted to officers of
     the Company, and shall have such other duties and responsibilities as the
     Board of Directors may from time to time determine;

          (ii)   an Audit Committee of the Board of Directors, consisting of
     three directors, one of whom shall be a WCAS Designee, if any then exist,
     one of whom shall be a Blackstone Designee, if any then exist, and one of
     whom shall be an Outside Director, which Audit Committee shall review and
     approve the financial statements of the Company as audited by the Company's
     independent certified public accountants, and shall have such other duties
     and responsibilities as the Board of Directors may from time to time
     determine; and

          (iii)  such other committees as the Board shall from time to time deem
     appropriate, consisting of at least two directors, at least one of whom
     shall be a WCAS Designee, if any then exist, and at least one of whom shall
     be a Blackstone Designee, if any then exist, which committees shall have
     such duties and responsibilities as the Board may from time to time
     determine.

          To the extent there are no WCAS Designees or Blackstone Designees, the
     committee seats allocated to them above shall be filled as the Board shall
     determine.

                                       3
<PAGE>

          (d)    No Stockholder shall grant any proxy or enter into or agree to
be bound by any voting trust with respect to Common Stock held by it, nor shall
any Stockholder enter into any stockholder agreement or arrangement of any kind
with respect to Common Stock held by it, which conflicts or is inconsistent in
any manner with the provisions of this Agreement.

          SECTION 2.  Restrictions on Transfers by Management Purchasers.  In
                      --------------------------------------------------
addition to the other restrictions set forth herein, each Management Purchaser
hereby agrees that such Management Purchaser shall not sell or in any other way,
directly or indirectly, transfer, assign, distribute or otherwise dispose of any
shares of capital stock (whether now owned or hereafter acquired) then held by
such Management Purchaser except:

          (i)    any transfer made with the prior written consent of the holders
     of a majority in interest of the shares of Common Stock then held by the
     WCAS Purchasers;

          (ii)   any transfer by such Management Purchaser to the spouse or
     lineal descendants of such Management Purchaser, including without
     limitation any transfer by bequest or devise, or to a trust or trusts for
     the benefit of such Management Purchaser or any of the foregoing;

          (iii)  any transfer of shares of capital stock that are the subject of
     an effective registration statement under the Securities Act of 1933, as
     amended (the "Securities Act"); or

          (iv)   any transfer of shares of capital stock pursuant to Section 3
or 4 hereof;

provided, in the case of a transfer pursuant to clause (i) or (ii) above, that
- --------
any such transferee that is not already a party to this Agreement shall agree in
writing to be bound by, and to comply with, all provisions of this Agreement as
though such transferee were a Management Purchaser.

          SECTION 3.  Tag-Along Rights.
                      ----------------

          (a)    Subject to the provisions of paragraph (d) below, if a WCAS
Purchaser or group of WCAS Purchasers (for purposes of this Section 3, a
"Selling Stockholder") wishes to directly or indirectly sell, transfer or
otherwise dispose of all or any portion of the Common Stock held by him, her or
it at any time, then such Selling Stockholder shall promptly deliver a notice
(an "Offering Notice") to the Company in writing of the proposed transfer,
specifying the number of such shares of Common Stock to be transferred by such
Selling Stockholder (such specified shares, the "Offered Shares"), the name of
the proposed purchaser or purchasers, the proposed purchase price per share, the
proposed date of transfer, the payment terms and all other material terms and
conditions thereof.  In the event that the terms and/or conditions set forth in
the Offering Notice are thereafter amended in any respect, the Selling
Stockholder shall also give written notice (an "Amended Notice") of the amended
terms and conditions of the proposed transaction to the Company.  Upon its
receipt of any Offering Notice or Amended Notice, the


                                       4
<PAGE>

Company shall promptly, but in all events within three (3) business days of its
receipt thereof, forward copies thereof to each of the Blackstone Purchasers,
Signal Purchasers, Management Purchasers and Guayacan Purchasers (collectively,
the "Other Stockholders"). The Selling Stockholder shall provide such additional
information with respect to the proposed transfer as may be reasonably requested
by the Company or the Other Stockholders.

          (b)    Each Other Stockholder shall have the right and option,
exercisable upon written notice to the Company and the Selling Stockholder
within 15 days after receipt by such Other Stockholder of the Offering Notice,
or, if later, within 7 days after receipt by such Other Stockholder of the most
recent Amended Notice, to participate in the proposed transfer of shares by the
Selling Stockholder to the proposed purchaser on the same terms and conditions
as the Selling Stockholder (such participation right being hereinafter referred
to as a "tag-along" right); provided that no Other Stockholder shall be required
                            --------
to make any representations or warranties or covenants, or bear any liability,
with respect to any other Stockholder or with respect to the Company or the
Company's business other than such Other Stockholder's pro rata share (based on
the number of shares of Common Stock to be transferred) of any indemnity
obligations for representations and warranties regarding the Company or its
business.  Each Other Stockholder may participate in such transfer with respect
to all or any part of that number of shares of Common Stock which is equal to
the product obtained by multiplying (i) the number of Offered Shares by (ii) a
fraction, the numerator of which is the number of shares of Common Stock at the
time owned by such Other Stockholder and the denominator of which is the
aggregate number of shares of Common Stock then owned by the Stockholders.  Any
Other Stockholders that have not notified the Selling Stockholder and the
Company of their intent to exercise their tag-along rights within 7 days after
receipt of an Amended Notice shall be deemed to have elected not to exercise
such rights with respect to the transaction contemplated by such Amended Notice
(regardless of their election pursuant to the Offering Notice or any prior
Amended Notice relating to such transaction), but only if such Amended Notice
sets forth the provisions of this sentence.

          (c)    Any Other Stockholder participating in the proposed disposition
shall deliver to the Company, as agent for such Other Stockholder, for transfer
to the proposed acquiror one or more certificates, properly endorsed for
transfer and with all stock transfer taxes paid and stamps affixed, which
represent the number of shares of Common Stock that such Other Stockholder
elects to dispose of pursuant to paragraph (b) above. The consummation of such
proposed disposition shall be subject to the sole discretion of the Selling
Stockholder, who shall have no liability or obligation whatsoever to any Other
Stockholder participating therein other than to obtain for such Other
Stockholder the same terms and conditions as those set forth in the Offering
Notice (or most recent Amended Notice, as the case may be). Upon the
consummation of any such sale, the Company (i) shall transfer to the acquiror a
stock certificate or certificates representing the number of shares of Common
Stock to be disposed of by any Other Stockholders and (ii) shall promptly
thereafter remit to each Other Stockholder (i) that portion of the proceeds of
the disposition to which such Other Stockholder is entitled by reason of such
participation and (ii) a stock certificate representing any balance of shares of
Common Stock that were not so

                                       5
<PAGE>

disposed of (or all shares of Common Stock, in the event the proposed
disposition is not consummated).

          (d) Anything to the contrary herein notwithstanding, the provisions of
this Section 3 shall not apply to (i) any transfer by a WCAS Purchaser to any
other WCAS Purchasers or affiliates thereof, (ii) any distribution or transfer
by any WCAS Purchaser that is a limited partnership to its limited partners or
(iii) in the case of a WCAS Purchaser who is an individual, transfer by such
WCAS Purchaser to the spouse or lineal descendants of such WCAS Purchaser,
including, without limitation, transfer by bequest or devise, or to a trust or
trusts for the benefit of such WCAS Purchaser or any of the foregoing; provided
that in the case of a transfer pursuant to clause (i) or (iii) above, such
transferee agrees in writing to be bound by this Agreement as though such
transferee were a WCAS Purchaser.

          (e) Each WCAS Purchaser, severally and not jointly, represents and
warrants to the Signal Purchasers and the Guayacan Purchasers that as of the
date hereof there is no contract, commitment or understanding between such
person and any Blackstone Purchaser with respect to "tag-along" or similar
rights relating to shares of capital stock of the Company, other than this
Agreement.  Each Blackstone Purchaser, severally and not jointly, represents and
warrants to the Signal Purchasers and the Guayacan Purchasers that as of the
date hereof there is no contract, commitment or understanding between such
person and any WCAS Purchaser with respect to "tag-along" or similar rights
relating to shares of capital stock of the Company, other than this Agreement.

          (f) Each Other Purchaser hereby waives its rights under this Section 3
with respect to the transfer on the date hereof of an aggregate 170,556 shares
of Common Stock from WCA Management Corporation to the Guayacan Purchasers.

          SECTION 4.  Drag-Along Rights.  In the event that any of the WCAS
                      -----------------
Purchasers or the Company receives a bona fide offer from a third party not
affiliated with any WCAS Purchaser to purchase at least 80% of the outstanding
shares of capital stock of the Company and a majority in interest of the WCAS
Purchasers desires to accept such offer, and so long as the WCAS Purchasers
collectively own a greater number of outstanding shares of Common Stock than the
Blackstone Purchasers, such WCAS Purchasers shall have the right to require all
(but not less than all) of the Stockholders to sell all (or such lesser
percentage as may be necessary to achieve recapitalization accounting treatment,
but in no event less than 80%) of the shares of capital stock (together with any
options or warrants to acquire capital stock) then held by them (including all
or the same percent of all shares, options and warrants held by such WCAS
Purchasers) on the following terms:

          (i) such sale shall only be a sale for cash or marketable securities
     and all expenses of the transaction, including, without limitation, legal,
     accounting and investment banking fees and expenses, shall be borne by the
     Company (for purposes of this paragraph, "marketable securities" shall mean
     securities which are debt or equity securities that are actively traded on
     a national securities exchange located in the United States or on Nasdaq


                                       6
<PAGE>

     that are part of an issue with a public capitalization in excess of $100
     million and that may be freely traded without limitation as to volume on
     such exchange or Nasdaq immediately following receipt thereof or at any
     time thereafter by each Stockholder);

          (ii)  the proceeds from such sale (and, in the case of a sale of less
     than all of the outstanding shares of Common Stock of the Company, the
     number of shares to be sold by each Stockholder) shall be allocated among
     the Stockholders on a pro rata basis, based on the number of shares of
                           --- ----
     Common Stock (treating all "in the money" options and warrants as the
     number of shares of Common Stock issuable upon the exercise thereof, less
     such number of shares of Common Stock the aggregate fair market value of
     which (based on the value attributed in such sale) would be required to pay
     the aggregate exercise price therefor, and treating any shares of
     convertible preferred stock or debt of the Company on an "as-converted"
     basis) then held by each Stockholder;

          (iii) not less than 20 days prior to the closing date of such sale,
     such WCAS Purchasers shall notify each of the other Stockholders in writing
     of such sale, the terms thereof and the closing date thereof, and shall
     provide additional written notification promptly upon any amendment or
     modification to any thereof, all of which terms shall apply equally to all
     Stockholders except that no Other Stockholder shall be required to make any
     representations, warranties or covenants, or bear any liability, with
     respect to the Company or the Company's business or with respect to any
     other Stockholder;

          (iv)  at the closing of such sale, each of the Stockholders shall
     deliver certificates evidencing the Common Stock, options and warrants then
     held by it and to be sold in such sale, duly endorsed for transfer or
     accompanied by stock powers executed in blank, against payment of the
     purchase price therefor by wire transfer to the account or accounts
     specified by such Stockholder; and

          (v)   the Other Stockholders shall not be obligated to participate in
     such sale if all of the WCAS Purchasers shall not have concurrently sold
     all or the same percentage of their shares of Common Stock, options and/or
     warrants to be sold by them in connection with such sale.

          SECTION 5.  Preemptive Rights.
                      -----------------

          (a)   The Company hereby grants to each Stockholder the right to
purchase such Stockholder's Proportionate Percentage (as hereinafter defined) of
any future Eligible Offering (as hereinafter defined). For the purposes of this
Section 5, the following terms shall have the meanings set forth below:

          "Proportionate Percentage" means, with respect to any Stockholder as
           ------------------------
     of any date, the result (expressed as a percentage) obtained by dividing
     (i) the number of shares of


                                       7
<PAGE>

     Common Stock owned by such Stockholder as of such date by (ii) the total
     number of shares of Common Stock outstanding as of such date.

          "Eligible Offering" means an offer by the Company to sell to any
           -----------------
     person or persons (including any of the Stockholders) for cash, cash
     equivalents or indebtedness any equity securities of the Company, or any
     security convertible into or exchangeable for, or carrying rights or
     options to purchase, equity securities of the Company, other than an
     offering by the Company:

               (i)   of shares of Common Stock or options to purchase shares of
          Common Stock in connection with or pursuant to any stock option or
          stock purchase plan approved by the Board of Directors of the Company
          to full-time employees, officers, directors, consultants and/or
          advisors to the Company or its subsidiaries;

               (ii)  in a public offering (a "Public Offering") registered under
          the Securities Act.

          (b)  The Company shall, before issuing any securities pursuant to an
Eligible Offering, give written notice thereof to each Stockholder.  Such notice
shall specify the security or securities the Company proposes to issue, the
proposed date of issuance, the consideration that the Company intends to receive
therefor and all other material terms and conditions of such proposed issuance.
For a period of 15 days following the date of such notice, each Stockholder
shall be entitled, by written notice to the Company, to elect to purchase all or
any part of such Stockholder's Proportionate Percentage of the securities being
sold in the Eligible Offering; provided, however, that if two or more securities
                               --------  -------
shall be proposed to be sold as a "unit" in an Eligible Offering, any such
election must relate to such unit of securities.  To the extent that elections
pursuant to this Section 5(b) shall not be made with respect to any securities
included in an Eligible Offering within such 15-day period, then the Company may
issue such securities, but only for consideration not less than, and otherwise
on no less favorable terms to the Company than, those set forth in the Company's
notice and only within 60 days after the end of such 15-day period.  In the
event that any such offer is accepted by a Stockholder or Stockholders, the
Company shall sell to such Stockholder or Stockholders, and such Stockholder or
Stockholders shall purchase from the Company, for the consideration and on the
terms set forth in the notice as aforesaid, the securities that such Stockholder
or Stockholders shall have elected to purchase.

          SECTION  6.  Right of First Offer.
                       --------------------

          (a)  If any Blackstone Purchaser (for purposes of this Section 6, a
"Seller") desires to sell, exchange or in any other manner dispose of (other
than in a manner permitted by Section 6(d) hereof) any shares of capital stock
of the Company held by it, then such Seller shall give to the Company a written
notice (a "Notice of Desire to Sell") which shall set forth in reasonable detail
the class and number of shares of capital stock which it desires to sell


                                       8
<PAGE>

and may, if the Seller so chooses to specify, set forth any other terms and
conditions of the desired disposition. The Company shall deliver such Notice of
Desire to Sell to each of the WCAS Purchasers promptly upon receipt thereof. A
Seller may deliver a Notice of Desire to Sell whether or not such Seller has
received an offer from a third party to purchase such shares of capital stock.

          (b)  The WCAS Purchasers shall have the right, exercisable upon
written notice to the Seller within 15 days after receipt of any Notice of
Desire to Sell (the "Offer Notice"), to offer to purchase any or all shares of
capital stock proposed to be sold by the Seller at a purchase price equal to the
proposed purchase price specified in the Notice of Desire to Sell if so
specified, or as proposed in the Offer Notice if not specified in the Notice of
Desire to Sell, and otherwise on the terms and conditions specified in the
Notice of Desire to Sell to the extent so specified and any additional terms and
conditions proposed in the Offer Notice (collectively, including with respect to
purchase price, the "Offer Terms"). Each Offer Notice shall state the number of
shares to be purchased by the WCAS Purchasers delivering such Offer Notice (the
"Purchasing Stockholders") and that the Purchasing Stockholders will purchase
such shares within 45 days thereafter (or such longer period as is necessary to
obtain any necessary consents or approvals or to otherwise comply with
applicable law). In the event that more than one WCAS Purchaser exercises its
right to offer to purchase pursuant to this paragraph (b), the allocation among
such WCAS Purchasers of any shares actually sold pursuant to this paragraph (b)
shall be as agreed by such WCAS Purchasers.

          (c)  If the WCAS Purchasers deliver, within the period specified in
paragraph (b) above, an Offer Notice with respect to capital stock that is the
subject of the Notice of Desire to Sell, the Seller shall be entitled to sell
such capital stock to such Purchasing Stockholders, on the Offer Terms within
the 45-day period specified in paragraph (b) above (or such longer period as is
necessary to obtain any necessary consents or approvals or to otherwise comply
with applicable law).  Following the period specified in paragraph (b) above,
the Seller may (subject to any other applicable restrictions hereunder) transfer
such capital stock to any third party; provided that, if an Offer Notice with
                                       --------
respect to all of such shares of capital stock was delivered within the 15 day
period specified in paragraph (b) above, the Seller may not sell such shares to
such third party on material terms which are the same as or more favorable, in
the aggregate, to such third party than the material terms set forth in the
Offer Terms.  Any such sale with respect to which definitive documentation is
not entered into within 60 days after the expiration of the period specified in
paragraph (b) above, or which is not consummated within 60 days of the execution
of such definitive documentation (or such longer period as is necessary to
obtain any necessary consents or approvals or to otherwise comply with
applicable law) shall again be subject to the requirements of this Section 6.

          (d)  Anything herein to the contrary notwithstanding, and subject to
any other applicable restrictions hereunder, no right of first offer hereunder
shall apply with respect to (i) a transfer by a Blackstone Purchaser to an
affiliate of such Blackstone Purchaser; provided, however, that any such
                                        --------  -------
transferee that is not already a party to this Agreement shall agree in


                                       9
<PAGE>

writing to be bound by, and to comply with, all provisions of this Agreement as
though such transferee were a Blackstone Purchaser, (ii) any distribution or
transfer by a Blackstone Purchaser that is a limited partnership to its limited
partners, (iii) any transfer by a Blackstone Purchaser to the public pursuant to
an offering registered under the Securities Act or sold in compliance with Rule
144 under the Securities Act and (iv) any transfer by a Blackstone Purchaser
pursuant to Section 3 or Section 4.

          SECTION 7.  Restrictions.
                      ------------

          (a)  While this Agreement is in effect, in addition to any other vote
of stockholders that may be required by law or by the Certificate of
Incorporation of the Company, the Company shall not, without the consent of (i)
the holders of a majority of the Common Stock then held by all the WCAS
Purchasers and (ii) the holders of a majority of the Common Stock then held by
all the Blackstone Purchasers:

          (i)  amend, alter or repeal its Certificate of Incorporation or its
     By-laws in any manner that adversely affects the respective rights,
     preferences or voting power of the Common Stock, or the rights of the
     Stockholders hereunder, it being understood that, in the event of any such

          SECTION 8.  Right and Option to Repurchase Shares of Common Stock From
                      ----------------------------------------------------------
Management Purchasers Upon Termination of Employment.
- ----------------------------------------------------

          (a)    In the event that any Management Purchaser ceases to be
employed by the Company or Centennial or any subsidiary thereof on a full-time
basis for any reason (including, without limitation, as a result of his death,
disability, incapacity, retirement, resignation or dismissal with or without
"cause" (as defined below)), the WCAS Purchasers shall have the right and
option, but not the obligation, to purchase from such Management Purchaser (or
in the case


                                      11
<PAGE>

of his death, his legal representative), in such proportions as the WCAS
Purchasers shall agree, any or all of the shares of Common Stock purchased by
such Management Purchaser pursuant to the Purchase Agreement (the "Repurchase
Shares"). In the event that the WCAS Purchasers exercise such right and option,
the WCAS Purchasers shall pay to such Management Purchaser as the purchase price
for such Repurchase Shares (the "Purchase Price"), an amount per share equal to
the fair market value thereof as of the date such Management Purchaser ceased to
be so employed by the Company or Centennial or any subsidiary thereof, such fair
market value to be determined in good faith by the Board on a basis consistent
with the manner of determining the fair market value of the Common Stock for
purposes of offering of the Company's Common Stock to equity investors (the
"Fair Market Value").

          (b) The WCAS Purchasers may exercise the right and option described in
Section 8(a) above by giving such Management Purchaser (or in the case of his
death, his legal representative) a written notice of election to purchase at any
time within 60 days after the date such employment ceases, which notice of
election shall specify the number of shares to be purchased by each electing
WCAS Purchaser and the Purchase Price for such shares.  The closing for the
purchase by the WCAS Purchasers of Repurchase Shares pursuant to Section 8(a)
will take place at the offices of Welsh, Carson, Anderson & Stowe on the date
specified in the written notice of election with respect to such shares, which
date shall be a business day not later than 60 days (or such longer period as is
necessary to obtain any necessary consents or approvals or to otherwise comply
with applicable law) after the date such notice is given.  At such closing, the
Management Purchaser (or in the case of his death, his legal representative)
will deliver such shares, duly endorsed for transfer, against payment in cash of
the Purchase Price thereof.

          (c) In the event that the WCAS Purchasers choose not to exercise their
rights and options under Section 8(a) hereof within the 60 day period referred
to in Section 8(b), the Company shall have the right and option, but not the
obligation, to purchase from the Management Purchaser whose employment was
terminated (or in the case of his death, his legal representative) any or all of
the Repurchase Shares.  In the event that the Company exercises such right and
option, the purchase price for such shares shall be the Purchase Price
determined in accordance with Section 8(a).

          (d) The Company may exercise the right and option described in Section
8(c) above by giving such Management Purchaser (or in the case of his death, his
legal representative) a written notice of election to purchase at any time
within 30 days after the expiration of the 60 day period referred to in Section
8(b) above, which notice of election shall specify the number of Repurchase
Shares to be purchased and the Purchase Price for such shares.  The closing for
the purchase by the Company of Repurchase Shares pursuant to Section 8(c) will
take place at the offices of the Company on the date specified in the written
notice of election with respect to such shares, which date shall be a business
day not later than 60 days (or such longer period as is necessary to obtain any
necessary consents or approvals or to otherwise comply with applicable law)
after the date such notice is given.  At such closing, the Management Purchaser
(or in the


                                      12
<PAGE>

case of his death, his legal representative) will deliver such shares, duly
endorsed for transfer, against payment in cash of the Purchase Price thereof.

          SECTION 9.  Financial and Other Information.  For so long as any
                      -------------------------------
Stockholder holds at least 25% of the Common Stock held by it as of the date
hereof, the Company shall furnish to such Stockholder:

     end of such fiscal year and the related consolidated statements of

     financial position of the Company and its subsidiaries for the quarter then

     Company, such balance sheet to be as of the end of such quarter and such
     statements of operations, changes in stockholders' equity and changes in
     financial position to be for such quarter and for the period from the
     beginning of the fiscal year to the end of such quarter, in each case
     subject to normal year-end adjustments;

          (iii) within 30 days after the end of each month in each fiscal year,
     a consolidated balance sheet of the Company and its subsidiaries and the
     related consolidated statement of operations for the month then ended,
     unaudited but certified by the principal financial officer of the Company,
     such balance sheet to be as of the end of such month and such statement of
     operations to be for such month and for the period from the beginning of
     the fiscal year to the end of such month, in each case subject to normal
     year-end adjustments;

          (iv)  promptly upon filing, copies of all registration statements,
     prospectuses, periodic reports and other documents filed by the Company
     with the SEC; and

          (v)   promptly, from time to time, such other information regarding
     the operations, business, affairs and financial condition of the Company or
     any subsidiary as such Stockholder may reasonably request, subject to such
     confidentiality agreements as the Company may reasonably request.

                       ----------------------------
representing shares of Common Stock owned by any Stockholder shall conspicuously
bear the following legend until such time as the shares represented thereby are
no longer subject to the provisions hereof:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
          TERMS AND CONDITIONS OF THE FIRST AMENDED AND RESTATED STOCKHOLDERS
          AGREEMENT, DATED AS OF JANUARY 20, 1999, AMONG THE COMPANY AND THE
          OTHER PARTIES THERETO.  COPIES MAY BE OBTAINED AT NO COST BY WRITTEN
          REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
          COMPANY."

          The Company covenants that it shall keep a copy of this Agreement on
file at the address listed in Section 19 for the purpose of furnishing copies to
the holders of record of shares of Common Stock.

          SECTION 11.  Duration of Agreement.  (a) This Agreement (other than
                       ---------------------
the provisions of Sections 1, 10, 11(b) and 15 through 25) shall terminate upon
the earlier to occur of (i) the tenth anniversary of the date hereof or (ii) the
consummation of (x) a Public Offering by the Company of Common Stock having an
aggregate offering price to the public of not less than $50,000,000, and (y) the
sale, transfer or other disposition (including a distribution by a limited
partnership to its partners) by either the WCAS Purchasers or the Blackstone
Purchasers to persons or entities not required to become parties hereto of at
least 50% of the shares of Common Stock held by the WCAS Purchasers or the
Blackstone Purchasers, as the case may be, on the date hereof.

          (b) The provisions of Sections 1, 10, 11(b) and 15 through 25 shall
terminate upon the earlier to occur of (i) the tenth anniversary of the date
hereof or (ii) the consummation of (x) a Public Offering by the Company of
Common Stock having an aggregate offering price to the public of not less than
$50,000,000, and (y) the sale, transfer or other disposition (including a
distribution by a limited partnership to its partners) by both of the WCAS
Purchasers and the Blackstone Purchasers to persons or entities not required to
become parties hereto of at least 50% of the shares of Common Stock held by the
WCAS Purchasers or the Blackstone Purchasers, respectively, on the date hereof.

          SECTION 12.  Advisory and Monitoring Fee.  On each anniversary of the

(i) $450,000, plus reasonable expenses, to WCA Management Corporation, or

majority of the Common Stock held by the Blackstone Purchasers, for so long as
the Blackstone Purchasers hold at least 25% of the shares of Common Stock held
by the Blackstone Purchasers on the date hereof. To the extent that payment of
such monitoring fees is prohibited by any provision of any credit agreement or
other debt instrument, the Company shall use commercially reasonable efforts to
cause the lender or holder of such debt instrument to waive any such
prohibition. If, despite such efforts, such lender or holder is unwilling to
permit the Company to pay such monitoring fee, then any amounts not so paid
shall accrue and shall bear interest at the rate of 13% per annum until paid,
and the Company shall promptly pay such sums when no such prohibitions exist.

          SECTION 13.  Representations and Warranties by the Stockholders.  Each
                       --------------------------------------------------
Stockholder, severally and not jointly, represents and warrants to the Company

indenture, agreement or other instrument.

          (b)  This Agreement has been duly executed and delivered by such
Stockholder, and when executed by the other parties hereto will constitute the
legal, valid and binding obligation of such Stockholder, enforceable in
accordance with its terms.

          (c)  The shares of Common Stock listed opposite the name of such
Stockholder on Schedule I, Schedule II, Schedule III, Schedule IV or Schedule V

not be increased thereby.  Except as expressly permitted hereby, each party=s
rights and obligations under this Agreement shall not be subject to assignment
or delegation by any party hereto, and any attempted assignment or delegation in
violation hereof shall be null and void ab initio.

among the Company and such parties.  Upon the merger of CCW with and into
Centennial Cellular Corp. (the "Company") on January 7, 1999, the Company
succeeded to all the rights and obligations of CCW under the Original

Purchasers, the Blackstone Purchasers, the Signal Purchasers and the Management
Purchasers, the "Purchasers") an aggregate 170,556 shares of Common Stock and in
connection therewith is assigning to the Guayacan Purchasers certain rights

the holder thereof shall give written notice to the Company of its intention to
effect such transfer.  Each such notice shall describe the manner of the
proposed transfer and, if reasonably requested by the Company, shall be
accompanied by an opinion of counsel reasonably satisfactory to the Company to
the effect that the proposed transfer of the Restricted Stock may be effected
without registration under the Securities Act, whereupon the holder of such
Restricted Stock shall be entitled to transfer such Restricted Stock in
accordance with the terms of its notice; provided, however, that no such opinion
                                         --------  -------
or other documentation shall be required if such notice shall cover a pro rata
distribution (without payment of additional consideration) by any Purchaser that
is a partnership or limited liability company to its partners or members, as the
case may be.  Each certificate for Restricted Stock transferred as above
provided shall bear the legend set forth in Section 2, unless (i) such transfer
is in accordance with the provisions of Rule 144 (or any other rule permitting
public sale without registration under the Securities Act or is pursuant to an
effective registration under the Securities Act) or (ii) the

                                       2
<PAGE>

opinion of counsel referred to above is to the further effect that (or, if no
opinion is required, the Company determines that) the transferee and any
subsequent transferee (other than an affiliate of the Company) would be entitled
to transfer such securities in a public sale without registration under the
Securities Act.

          The foregoing restrictions on transferability of Restricted Stock
shall terminate as to any particular shares of Restricted Stock when such shares
shall have been effectively registered under the Securities Act and sold or
otherwise disposed of in accordance with the intended method of disposition by
the seller or sellers thereof set forth in the registration statement concerning
such shares.  Whenever a holder of Restricted Stock is able to demonstrate to
the Company (and its counsel) that the provisions of Rule 144(k) of the
Securities Act are available to such holder without limitation, such holder of
Restricted Stock shall be entitled to receive from the Company, without expense,
a new certificate not bearing the restrictive legend set forth in Section 2.

          4.  Required Registration.
              ---------------------

          (a) At any time after January 7, 2002, the holders of a majority of
     the outstanding Restricted Stock then held by the WCAS Purchasers or the
     Blackstone Purchasers may request the Company to register under the
     Securities Act all or any portion of the Restricted Stock held by such
     requesting holder or holders for sale in the manner specified in such
     notice; provided, however, that neither the WCAS Purchasers nor the
             --------  -------
     Blackstone Purchasers may request registration pursuant to this Section 4
     more than once every six months.

          (b) Promptly following receipt of any notice under this Section 4, the
     Company shall immediately notify any holders of Restricted Stock from whom
     notice has not been received and shall use its best efforts to register as
     soon as possible under the Securities Act, for public sale in accordance
     with the method of disposition specified in such notice from the original
     requesting holders, the number of shares of Restricted Stock specified in
     such notice (and in any notices received from other holders of Restricted
     Stock within 20 days after their receipt of such notice from the Company);
     provided, however, that if the proposed method of disposition specified by
     --------  -------
     the original requesting holders shall be an underwritten public offering,
     the number of shares of Restricted Stock to be included in such an offering
     may be reduced (pro rata among the requesting holders of Restricted Stock
                     --- ----
     based on the number of shares of Restricted Stock so requested to be
     registered) if and to the extent that the managing underwriter shall be of
     the opinion that such inclusion would adversely affect the marketing of the
     Restricted Stock to be sold.  In the event that the proposed method of
     disposition specified by the original requesting holders shall be an
     underwritten public offering, the original requesting holders may choose
     the managing underwriter (which shall be a nationally recognized investment
     banking firm), subject to the consent of the Company (which shall not be
     unreasonably withheld).  Notwithstanding anything to the contrary contained
     herein, the obligation of

                                       3
<PAGE>

     the Company under this Section 4 shall be deemed satisfied only when a
     registration statement covering all shares of Restricted Stock specified in
     notices received as aforesaid (subject to any cutbacks as contemplated
     hereinabove), for sale in accordance with the method of disposition
     specified by the requesting holder, shall have become effective and, if
     such method of disposition is a firm commitment underwritten public
     offering, all such shares shall have been sold pursuant thereto.

          (c) The Company shall be entitled to include in any registration
     statement referred to in this Section 4, for sale in accordance with the
     method of disposition specified by the requesting holders, shares of Common
     Stock to be sold by the Company for its own account, except as and to the
     extent that, in the opinion of the managing underwriter (if such method of
     disposition shall be an underwritten public offering), such inclusion would
     adversely affect the marketing of the Restricted Stock to be sold (and in
     such event, such shares to be sold by the Company for its own account shall
     be reduced or eliminated before any reduction in the number of shares to be
     sold by requesting holders pursuant to Section 4(b)).  Except as provided
     in this paragraph (c), the Company will not effect any other registration
     of its Common Stock, whether for its own account or that of other holders,
     from the date of receipt of a notice from requesting holders pursuant to
     this Section 4 until the completion of the period of distribution of the
     registration contemplated thereby.

          5.  Incidental Registration.  If the Company at any time (other than
              -----------------------
pursuant to Section 4 hereof) proposes to register any of its Common Stock under
the Securities Act for sale to the public, whether for its own account or for
the account of other securityholders or both (except with respect to
registration statements on Form S-4 or S-8 or another form not available for
registering the Restricted Stock for sale to the public), it will give written
notice at such time to all holders of outstanding Restricted Stock of its
intention to do so.  Upon the written request of any such holder, given within
20 days after receipt of any such notice by the Company, to register any of its
Restricted Stock (which request shall state the intended method of disposition
thereof), the Company will use its best efforts to cause the Restricted Stock,
as to which registration shall have been so requested, to be included in the
securities to be covered by the registration statement proposed to be filed by
the Company, all to the extent requisite to permit the sale or other disposition
by the holder (in accordance with its written request) of such Restricted Stock
so registered; provided that nothing herein shall prevent the Company from
               --------
abandoning or delaying such registration at any time.  In the event that any
registration pursuant to this Section 5 shall be, in whole or in part, an
underwritten public offering of Common Stock, any request by a holder pursuant
to this Section 5 to register Restricted Stock shall specify that either (i)
such Restricted Stock is to be included in the underwriting on the same terms
and conditions as the shares of Common Stock otherwise being sold through
underwriters under such registration or (ii) such Restricted Stock is to be sold
in the open market without any underwriting, on terms and conditions comparable
to those normally applicable to offerings of common stock in reasonably similar
circumstances.  The number of shares of Restricted Stock to be included in such
an underwriting may be reduced (pro rata among the holders of Restricted
                                --- ----

                                       4
<PAGE>

Stock requesting registration pursuant to this Section 5 based upon the number
of shares of Restricted Stock so requested to be registered) if and to the
extent that the managing underwriter shall be of the opinion that such inclusion
would adversely affect the marketing of the securities to be sold by the Company
therein; provided, however, that such number of shares of Restricted Stock shall
         --------  -------
not be reduced if any shares are to be included in such underwriting for the
account of any person other than the Company and the holders of Restricted
Stock.

          Notwithstanding anything to the contrary contained in Section 4 or 5
hereof, in the event that there is a firm commitment underwritten public
offering of securities of the Company pursuant to a registration covering
Restricted Stock and a holder of Restricted Stock does not elect to sell his
Restricted Stock to the underwriters of the Company's securities in connection
with such offering, such holder shall, to the extent required by such
underwriters with respect to all holders of Restricted Stock, refrain from
selling such Restricted Stock so registered pursuant to this Section 5 during
the period of distribution of the Company's securities by such underwriters and
the period in which the underwriting syndicate participates in the after market;
provided, however, that such holder shall, in any event, be entitled to sell its
- --------  -------
Restricted Stock commencing on the 120th day after the effective date of such
registration statement.

          6.  Registration Procedures and Expenses.  If and whenever the Company
              ------------------------------------
is required by the provisions of Section 4 or 5 hereof to use its best efforts
to effect the registration of any of the Restricted Stock under the Securities
Act, the Company will, as expeditiously as possible:

          (a) prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon) and file with the Commission a
     registration statement (which, in the case of an underwritten public
     offering pursuant to Section 4 hereof, shall be on Form S-1, S-3 or another
     form of general applicability satisfactory to the managing underwriter
     selected as therein provided) with respect to such securities and use its
     best efforts to cause such registration statement to become and remain
     effective for the period of the distribution contemplated thereby
     (determined as hereinafter provided);

          (b) prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon)  and file with the Commission
     such amendments and supplements to such registration statement and the
     prospectus used in connection therewith and any documents incorporated by
     reference therein and file such other documents as may be necessary to keep
     such registration statement effective for the period specified in paragraph
     (a) above and to comply with the provisions of the Securities Act with
     respect to the disposition of all Restricted Stock covered by such
     registration statement in accordance with the sellers' intended method of
     disposition set forth in such registration statement for such period;

          (c) furnish to each seller and to each underwriter such number of
     copies of the registration statement and the prospectus included therein
     (including each preliminary

                                       5
<PAGE>

     prospectus), and all amendments, supplements, and exhibits thereto, and
     such other documents as such persons may reasonably request in order to
     facilitate the public sale or other disposition of the Restricted Stock
     covered by such registration statement (and the Company hereby consents to
     the use of any such prospectus, together with such supplements and
     amendments, by the sellers and underwriters, if any, in connection with the
     offer and sale covered thereby);

          (d) use its best efforts to register or qualify the Restricted Stock
     covered by such registration statement under the securities or blue sky
     laws of such jurisdictions as the sellers of Restricted Stock or, in the
     case of an underwritten public offering, the managing underwriter, shall
     reasonably request (provided that the Company will not be required to (i)
     qualify generally to do business in any jurisdiction where it would not
     otherwise be required to qualify but for this paragraph (d), (ii) subject
     itself to taxation in any such jurisdiction or (iii) consent to general
     service of process in any jurisdiction);

          (e) immediately notify each seller under such registration statement
     and each underwriter, (i) when such registration statement or any post-
     effective amendment or supplement thereto becomes effective; (ii) of the
     issuance by the SEC or any state securities authority of any stop order,
     injunction or other order or requirement suspending the effectiveness of
     such registration statement (and the Company shall use best efforts to
     prevent the initiation of proceedings for, prevent the entry of and/or
     remove such order or requirement); or (iii) of the happening of any event
     as a result of which such registration statement, as then in effect, the
     prospectus contained therein or any document incorporated by reference
     therein includes an untrue statement of a material fact or omits to state
     any material fact required to be stated therein or necessary to make the
     statements therein not misleading in the light of the circumstances then
     existing;

          (f) use its best efforts to furnish, at the request of any seller, on
     the date that Restricted Stock is delivered to the underwriters for sale
     pursuant to such registration, if such securities are being sold through
     underwriters, or on the date that the registration statement becomes
     effective, if such securities are not being sold through underwriters:  (i)
     an opinion dated such date of counsel representing the Company for the
     purposes of such registration, addressed to the underwriters, if any, and
     to such seller, stating that such registration statement has become
     effective under the Securities Act and that (A) to the best knowledge of
     such counsel, no stop order suspending the effectiveness thereof has been
     issued and no proceedings for that purpose have been instituted or are
     pending or contemplated under the Securities Act, (B) the registration
     statement, the related prospectus, and each amendment or supplement
     thereof, comply as to form in all material respects with the requirements
     of the Securities Act and the applicable rules and regulations of the
     Commission thereunder (except that such counsel need express no opinion as
     to financial statements, the notes thereto, and the financial schedules and
     other financial and statistical data contained therein) and (C) to such
     other effects as may reasonably be requested by counsel for the
     underwriters or by such seller or its counsel,

                                       6
<PAGE>

     and (ii) a letter dated such date from the independent public accountants
     retained by the Company, addressed to the underwriters, if any, and to such
     sellers stating that they are independent public accountants within the
     meaning of the Securities Act and that, in the opinion of such accountants,
     the financial statements of the Company included in the registration
     statement or the prospectus, or any amendment or supplement thereof, comply
     as to form in all material respects with the applicable accounting
     requirements of the Securities Act, and such letter shall additionally
     cover such other financial matters (including information as to the period
     ending no more than five business days prior to the date of such letter)
     with respect to the registration in respect of which such letter is being
     given as such underwriters or sellers may reasonably request;

          (g) take such actions as may be necessary or appropriate to obtain a
     CUSIP number (if none exists) for the Common Stock, and make all filings
     and secure all approvals required pursuant to the regulations of the
     National Association of Securities Dealers, Inc. in connection with such
     registration;

          (h) take such actions as may be necessary or appropriate to cause the
     Restricted Stock so to be registered to be listed on the principal
     securities exchange (or on the NASDAQ National Market System, as the case
     may be) on which the Company's Common Stock is then traded (or, in the case
     of an initial public offering, on such national securities exchange (or on
     the NASDAQ National Market System) as the Company shall elect);

          (i)  use its best efforts to comply with all applicable rules and
     regulations of the SEC, and make available to any holder of Restricted
     Stock, as soon as reasonably practicable (but not more than 15 months)
     after the effective date of the registration statement, an earnings
     statement which shall satisfy the provisions of Section 11(a) of the
     Securities Act and the rules and regulations promulgated thereunder; and

          (j) make available for inspection by each seller, any underwriter
     participating in any distribution pursuant to such registration statement,
     and any attorney, accountant or other agent retained by such seller or
     underwriter, all financial and other records, pertinent corporate documents
     and properties of the Company, and cause the Company's officers, directors
     and employees to supply all information reasonably requested by any such
     seller, underwriter, attorney, accountant or agent in connection with such
     registration statement and permit such seller, attorney, accountant or
     agent to participate in the preparation of such registration statement.

For purposes of paragraphs (a) and (b) above and of Section 4(c) hereof, the
period of distribution of Restricted Stock in a firm commitment underwritten
public offering shall be deemed to extend until each underwriter has completed
the distribution of all securities purchased by it, and the period of
distribution of Restricted Stock in any other registration shall be deemed

                                       7
<PAGE>

to extend until the earlier of the sale of all Restricted Stock covered thereby
or six months after the effective date thereof.

          In connection with each registration hereunder, the selling holders of
Restricted Stock will furnish to the Company in writing such information with
respect to themselves and the proposed distribution by them as shall be
reasonably necessary in order to assure compliance with federal and applicable
state securities laws.

          In connection with each registration pursuant to Sections 4 and 5
hereof covering an underwritten public offering, the Company agrees to enter
into a written agreement with the managing underwriter selected in the manner
herein provided in such form and containing such provisions as are customary in
the securities business for such an arrangement between major underwriters and
companies of the Company's size and investment stature; provided, however, that
                                                        --------  -------
such agreement shall not contain any such provision applicable to the Company
which is inconsistent with the provisions hereof and provided, further, however,
                                                     --------  -------  -------
that the time and place of the closing under said agreement shall be as mutually
agreed upon among the Company,  such managing underwriter and the selling
holders of Restricted Stock.

          7.  Expenses.  All expenses incurred by the Company in complying with
              --------
Sections 4 and 5 hereof, including, without limitation, all registration,
listing and filing fees, printing expenses, fees and disbursements of counsel
and independent public accountants for the Company (including with respect to
any special audit or Acold comfort@ letters), fees of the National Association
of Securities Dealers, Inc., transfer taxes and fees of transfer agents and
registrars, as well as fees and expenses of counsel for the sellers of
Restricted Stock, but excluding any Selling Expenses, are herein called
"Registration Expenses."  All underwriting discounts and selling commissions
applicable to the sale of Restricted Stock are herein called "Selling Expenses."

          The Company will pay all Registration Expenses in connection with each
registration statement filed pursuant to Section 4 or 5 hereof.  All Selling
Expenses in connection with any registration statement filed pursuant to Section
4 or 5 hereof shall be borne by the participating sellers in proportion to the
number of shares sold by each, or by such persons other than the Company (except
to the extent the Company shall be a seller) as they may agree.

          8.  Indemnification.  In the event of a registration of any of the
              ---------------
Restricted Stock under the Securities Act pursuant to Section 4 or 5 hereof, the
Company will indemnify and hold harmless, to the fullest extent permitted by
law, each seller of such Restricted Stock thereunder, each underwriter of
Restricted Stock thereunder, each of their respective affiliates, each of their
and their affiliates' respective directors, officers, fiduciaries, agents,
employees, stockholders, general and limited partners and members, and each
other person, if any, who controls such seller or underwriter within the meaning
of the Securities Act, against any losses, claims, damages or liabilities, joint
or several, actions or proceedings (whether commenced or threatened) in respect
thereof (all of the foregoing, collectively, "Claims") and expenses (including

                                       8
<PAGE>

fees and expenses of counsel, and amounts paid in any settlement effected with
the Company's consent, which consent shall not be unreasonably withheld or
delayed) to which such indemnified party may become subject under the Securities
Act or otherwise, insofar as such Claims or expenses arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such Restricted Stock was
registered under the Securities Act pursuant to Section 4 or 5, any preliminary
prospectus, summary or final prospectus contained therein, or any amendment or
supplement of any thereof, or any documents incorporated by reference therein,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such indemnified
party for any legal or other expenses incurred by them in connection with
investigating or defending any such Claim; provided, however, that the Company
                                           --------  -------
will not be liable to any such indemnified party if and to the extent that any
such Claim or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission so made in conformity
with information pertaining to such indemnified party furnished by such
indemnified party in writing specifically for use in such registration statement
or prospectus.

          In the event of a registration of any of the Restricted Stock under
the Securities Act pursuant to Section 4 or 5 hereof, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless, to the fullest extent permitted by law, the Company and each person,
if any, who controls the Company within the meaning of the Securities Act, each
officer of the Company who signs the registration statement, each director of
the Company, each underwriter and each person who controls any underwriter
within the meaning of the Securities Act, each other stockholder selling
Restricted Stock under such registration statement and each affiliate, officer,
director, fiduciary, agent, employee, stockholder, general or limited partner or
member of such selling stockholder against all Claims and expenses (including
fees and expenses of counsel, and amounts paid in any settlement effected with
the Company's consent, which consent shall not be unreasonably withheld or
delayed) to which the Company or such officer or director or underwriter or
controlling person may become subject under the Securities Act or otherwise,
insofar as such Claims or expenses arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the
registration statement under which such Restricted Stock was registered under
the Securities Act pursuant to Section 4 or 5, any preliminary prospectus,
summary or final prospectus contained therein, or any amendment or supplement of
any thereof, or any documents incorporated by reference therein, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and will reimburse the Company and each such indemnified party
for any legal or other expenses incurred by them in connection with
investigating or defending any such Claim; provided, however, that such seller
                                           --------  -------
will be liable hereunder to any such indemnified party if and only to the extent
that any such Claim or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with information pertaining to such seller, as
such, furnished in writing to the Company by such indemnified party specifically
for use in such registration statement or prospectus; provided,
                                                      --------

                                       9
<PAGE>

further, however, that the liability of each seller hereunder shall be limited
- -------  -------
to the proceeds (net of underwriting discounts and commissions) received by such
seller from the sale of Restricted Stock covered by such registration statement.

          Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party under this Section 8 except to the extent such
indemnifying party is materially prejudiced thereby, and in any event will not
relieve such indemnifying party from any liability which it may have to any
indemnified party other than under this Section 8.  In case any such action
shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 8 for any
legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation and of
liaison with counsel so selected; provided, however, that, if the defendants in
                                  --------  -------
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
reasonable defenses available to it which are different from or additional to
those available to the indemnifying party, or if the interests of the
indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, or if the indemnifying party shall not diligently continue
such defense in good faith, the indemnified party shall have the right to select
a separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.

          Notwithstanding the foregoing, any indemnified party shall have the
right to retain its own counsel in any such action, but except as set forth
above the fees and disbursements of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party shall have failed to retain
counsel for the indemnified person as aforesaid or (ii) the indemnifying party
and such indemnified party shall have mutually agreed to the retention of such
counsel.  It is understood that the indemnifying party shall not, in connection
with any action or related actions in the same jurisdiction, be liable for the
fees and disbursements of more than one firm (together with local counsel) to
act as counsel for the indemnified party.  The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment.  No indemnifying party
shall, without the written consent of the indemnified party (which shall not be
unreasonably withheld or delayed), effect the settlement or compromise of, or
consent to the entry of any

                                       10
<PAGE>

judgment with respect to, any pending or threatened action in respect of which
indemnification may be sought hereunder (whether or not the indemnified party is
an actual or potential party to such action) unless such settlement, compromise
or judgment (i) includes an unconditional release of such indemnified party from
all liability arising out of such action and (ii) does not include a statement
as to or an admission of fault, culpability or a failure to act by or on behalf
of such indemnified party.

          If for any reason the indemnification provided for in the first two
paragraphs of this Section 8 is unavailable or insufficient to hold harmless an
indemnified party under such paragraphs in respect of any Claims or expenses in
respect thereof referred to therein, then each indemnifying party shall in lieu
of indemnifying such indemnified party contribute to the amount paid or payable
by such indemnified party as a result of such Claims or expenses in such
proportion as appropriate to reflect the relative fault of the Company, on the
one hand, and the underwriters and the sellers of such Restricted Stock, on the
other, in connection with the statements or omissions which resulted in such
Claims or expenses as well as any other relevant equitable considerations,
including the failure to give any notice under the third paragraph of this
Section 8.  The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by the indemnifying party, on the one hand, or
the indemnified party, on the other, and to the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The Company and each of you agree that it would not be
just and equitable if contributions pursuant to this paragraph were determined
by pro rata allocation (even if all of the sellers of such Restricted Stock were
   --- ----
treated as one entity for such purpose) or by any other method of allocation
which did not take account of the equitable considerations referred to above in
this paragraph.  The amount paid or payable by an indemnified party as a result
of the Claims and expenses in respect thereof, referred to above in this
paragraph, shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim.  Notwithstanding the provisions of this paragraph, no
seller of such Restricted Stock or related indemnified party shall be required
to contribute any amount in excess of the amount of proceeds (net of
underwriting discounts and commissions) received by such seller from the sale of
Restricted Stock covered by such registration statement.  No person guilty of
fraudulent misrepresentations (within the meaning of Section 11(f) of the
Securities Act), shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation.

          The indemnification of underwriters provided for in this Section 8
shall be on such other terms and conditions as are at the time customary and
reasonably required by such underwriters.  In that event the indemnification of
the sellers of Restricted Stock in such underwriting shall at the sellers'
request be modified to conform to such terms and conditions.

          The indemnification and contribution agreements contained herein shall
be in addition to any other rights to indemnification and contribution which any
indemnified party may have pursuant to law or contract or otherwise, shall
remain operative and in full force and effect

                                       11
<PAGE>

regardless of any investigation made or omitted by or on behalf of any
indemnified party and shall survive the transfer of Restricted Stock by any such
party.

          9.   Changes in Common Stock.  If, and as often as, there are any
               -----------------------
changes in the Common Stock by way of stock split, stock dividend, combination
or reclassification, or through merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof, as may be required, so that the rights and privileges
granted hereby shall continue with respect to the Common Stock as so changed.

          10.  Representations and Warranties of the Company.  The Company
               ---------------------------------------------
represents and warrants to you as follows:

          (a)  The execution, delivery and performance of this Agreement by the
     Company have been duly authorized by all requisite corporate action and
     will not violate any provision of law, any order of any court or other
     agency of government, the Certificate of Incorporation or By-laws of the
     Company, or any provision of any indenture, agreement or other instrument
     to which it or any of its properties or assets is bound, or conflict with,
     result in a breach of or constitute (with due notice or lapse of time or
     both) a default under any such indenture, agreement or other instrument, or
     result in the creation or imposition of any lien, charge or encumbrance of
     any nature whatsoever upon any of the properties or assets of the Company.

          (b)  This Agreement has been duly executed and delivered by the
     Company and constitutes the legal, valid and binding obligation of the
     Company, enforceable in accordance with its terms, subject to
     considerations of public policy in the case of the indemnification
     provisions hereof.

          (c)  The Company hereby incorporates by reference and makes the
     representations and warranties set forth in the Purchase Agreement, to the
     extent applicable to this Agreement or the transactions contemplated
     hereby, as of the date hereof.

          11.  Rule 144 Reporting.  The Company agrees with you as follows:
               ------------------

          (a)  The Company shall make and keep public information available, as
     those terms are understood and defined in Rule 144 under the Securities
     Act, at all times as it is able to do so.

          (b)  The Company shall file with the Commission in a timely manner all
     reports and other documents as the Commission may prescribe under Section
     13(a) or 15(d) of the Exchange Act at any time that the Company is subject
     to such reporting requirements of the Exchange Act.

                                       12
<PAGE>

          (c)  The Company shall furnish to any holder of Restricted Stock
     forthwith upon request (i) a written statement by the Company as to its
     compliance with the reporting requirements of Rule 144, and of the
     Securities Act and the Exchange Act, (ii) a copy of the most recent annual
     or quarterly report of the Company, and (iii) such other reports and
     documents so filed as a holder may reasonably request to avail itself of
     any rule or regulation of the Commission allowing a holder of Restricted
     Stock to sell any such securities without registration.

          12.  Miscellaneous.
               -------------

          (a)  All covenants and agreements contained in this Agreement by or on
     behalf of any of the parties hereto shall bind and inure to the benefit of
     the respective successors and permitted assigns of the parties hereto
     whether so expressed or not.  Without limiting the generality of the
     foregoing, any holder of Restricted Stock may assign its rights hereunder
     with respect to any of its Restricted Stock to any transferee of such
     Restricted Stock, provided that such transferee agrees in writing to become
                       --------
     a party hereto and to be bound as a holder of Restricted Stock hereby, and
     provided further that any WCAS Purchaser or Blackstone Purchaser shall
     --------
     specify in such assignment whether it is assigning rights under Section 4
     hereof (in which case such transferee shall become entitled to the rights
     and subject to the obligations hereunder as fully to the same extent as,
     and shall deemed to be, a WCAS Purchaser or Blackstone Purchaser, as the
     case may be, hereunder) and, if assigning such rights, shall be entitled in
     such assignment to limit the ability of such transferee to further transfer
     such rights (and such status as a WCAS Purchaser or Blackstone Purchaser,
     as the case may be) to additional transferees.

          (b)  All notices, requests, consents and other communications
     hereunder shall be in writing and shall be delivered personally, sent by
     nationally recognized overnight courier services, transmitted by confirmed
     telecopy or mailed by first class registered mail, postage prepaid,
     addressed as follows:

          if to the Company, to it at:

          if to any Purchaser, to it at its address set forth on Schedule I,
     Schedule II, Schedule III, Schedule IV or Schedule V hereto, as the case
     may be;

          if to any subsequent holder of Restricted Stock, to it at such address
     as may have been furnished to the Company in writing by such holder;

     or, in any case, at such other address or addresses as shall have been
     furnished in writing to the Company (in the case of a holder of Restricted
     Stock) or to the holders of Restricted Stock (in the case of the Company).

          (c)  This Agreement shall be governed by and construed in accordance
     with the laws of the State of Delaware.

          (d)  This Agreement constitutes the entire agreement of the parties
     with respect to the subject matter hereof (without limiting the foregoing,
     the Original Registration Rights Agreement is hereby superseded in its
     entirety) and may not be modified or amended except in writing signed by,
     and the Company will not grant any registration rights to any other person
     without the consent of, the holders of a majority in interest of the
     Restricted Stock held by each of (i) the WCAS Purchasers, (ii) the
     Blackstone Purchaser and (iii) if adversely affected thereby, the other
     holders of Restricted Stock.  Any waiver of any provision of this Agreement
     must be in a writing signed by the party against whom enforcement of such
     waiver is sought.

          (e)  This Agreement may be executed in two or more counterparts, each
     of which shall be deemed an original, but all of which together shall
     constitute one and the same instrument.

          (f)  Headings and section reference numbers in this Agreement are for
     reference purposes only and shall not in any way affect the meaning or
     interpretation of this Agreement.

          (g)  In the event that any one or more of the provisions set forth
     herein shall, for any reason, be held to be invalid, illegal or
     unenforceable in any respect, such invalidity, illegality or
     unenforceability shall not affect any other provision of this Agreement.

          (h)  Except as specifically set forth in Section 8 hereof, this
     Agreement is not intended to confer any rights or remedies upon any person
     other than the parties hereto.

          (i)   Each party hereto agrees that a remedy at law for any breach or
     threatened breach by such party of this Agreement would be inadequate and
     therefore agrees that any

                                       14
<PAGE>

     other party hereto shall be entitled to specific performance of this
     Agreement in addition to any other available rights and remedies in case of
     any such breach or threatened breach.
